The Book of Maiden Contract

When Lin Luo and the Dark King teamed up to attack the Evil King, Sky City also entered a state of emergency preparations, and the twelve floating cities distributed around the main city sounded violent alarms...the alarms were set by Chao Lingyin himself.

The method of collecting information is the screen, and the captured people and objects are simulated and converted into combat power values ​​through specific data. According to the level of combat power, the alert level is temporarily divided into seven levels. Level 4 and below are all within the range they can solve. Level 5 is about to fall into a rather hard fight. Level 6 is a desperate situation. As for level 7... that is already an invincible level.

At this moment, all the sirens in Sky City have reached level five at least!

"Damn it, how did this happen!" When the siren sounded, the first thing that came to mind was the super ring tone. Before, she had just finished the experiment for three consecutive days and three nights, and she was planning to take a good rest. She was awakened without even closing her eyes. When she saw the screen and combat power value fed back from the siren, she couldn't believe it.

Since the birth of these sirens, it's not that she hasn't heard of level 5 alarms, even level 7 alarms, but the so-called level 7 alarms were not triggered by others, but by Ewen Jielin, but now... those countless people rushing from all directions like ants colonies are the real enemies!

The main hall on the seventh floor of the Sky City has become her main activity place after being transformed by Chaolingyin, and it is here for both experiments and rest. This may be unbearable to others, but as a "scientist who sold his soul to science", Chaolingyin is not only not bored, but very excited. Apart from the necessary communication with other people, he spends almost 20 hours a day here, and sometimes even stays for several days in a row, enjoying it.

Now, Chao Lingyin was sitting in front of the main console, typing on the keyboard with a hand speed that was almost twice as fast as a normal person, with a serious expression on his face. In the row next to her, Chachawan and several robots made by Chaolingyin were also doing the same job.

Their main task is to completely analyze the enemy's data, including weaknesses and specialties, and then feed these data back to the fighters outside, so that they can make targeted attacks and defenses.

"Attention, there are about 1,000 enemy troops in front of us. They are undead. It is preliminarily estimated that their strength is above the spiritual level. Among them, 30% have reached the middle level of the spirit level, and very few individuals have reached the high level of the spirit level...the danger level is five!" Data analysis is what Chao Lingyin is best at. In less than a moment, she got some specific information about the enemy, and then passed all the information to the outside receiver through the communicator.

"The number of enemies directly behind is the same as above. They are of the Warcraft system, and all of them are flying monsters. The defense strength is quite abnormal. The strength level is above the spiritual level, and some individuals have reached the high level of the spiritual level... the danger level is five!"

"There are about 2,000 enemies at four o'clock on the right. They are the ghost army. They are immune to all physical attacks. Their strength is extremely terrifying. There are multiple high-level spiritual ranks...Damn it, why are there so many? The danger level is six!"

"The number of enemies at ten o'clock on the left is more than 3,000, all of them are orc legions, and their strength ratings... Uh! Ling... the peak of the spiritual rank! The peak of the spiritual rank with more than two digits! No, we will all be wiped out!" When seeing the data displayed in front of him, Chao Lingyin was shocked, with an unconcealable fear on his face. There are so many peak spiritual ranks, they can't stop them no matter what.

"Don't worry, someone from the orc army has already resisted us, it's the Dragon Clan!" At this moment, a girl's voice came from the communicator in Chao Lingyin's hands, and said very calmly.

Hearing this sentence, Chao Lingyin quickly pressed on the keyboard. Sure enough, because he focused on the enemy's data analysis just now, he didn't find it. At this moment, thousands of dragons have already killed those orc legions, blocking the opponent's offensive. The two sides are in a stalemate.

"Damn, why are there so many enemies all at once? We don't even have time to fully prepare, and Teacher Lin Luo is not here..." Although the most dangerous enemy has been blocked by their strongest defenders, Chao Lingyin still couldn't feel relieved and couldn't help but say.

In fact, when the siren sounded, the nuclear bomb she made had already been launched. With the terrifying lethality of the nuclear bomb, most of the enemies could be wiped out in an instant, but... the nuclear bomb needs a certain amount of time to activate, and this time is enough for those high-level enemies to "destroy" the nuclear bomb. After all, although most of the invaders are not human, they are not without brains.

Therefore, none of the nuclear bombs she dropped exploded.

"Calm down, super ring tone." The girl's voice came again from the communicator, "We live here. No matter how many enemies come, we must protect this world. This is inevitable since we participated in the battle of gods. It's just that the expected situation is a little earlier. Also... You haven't slept for several days after doing research. I feel that your spirit is in a state of extreme tension. I suggest you take a break."

"Are you kidding? How can I rest at a time like this? Don't worry about me. I have a way to adjust myself." Almost without thinking, Chao Lingyin retorted loudly. Although she knew that the other party was doing it for her own good, and she also knew that her current mental state was not suitable for this kind of work, but... How could she ignore the current besieged situation.

If I go to rest now, I am afraid that there will be no time to rest in the future.

The girl on the opposite side seemed to know that Chao Lingyin would not go to rest, and did not object. The calm voice not only encouraged Chao Lingyin, but also encouraged herself, "Okay, then let's do our guard work well... This is our war, we can win or lose."

"Well, but don't be too brave. The enemy this time is really terrifying. If you really can't beat it, use the teleporter I made to return to Sky City. At least there are no earth-level strongmen. Sky City's defense is still absolute." Chao Lingyin nodded, and then both parties exited the communication mode.

"Chachawan, you take over the enemy's data analysis." After finishing the call, Chao Lingyin stood up and said to the girl next to him as he walked towards the exit of the control room.

Chachawan immediately sat on Chao Lingyin's seat, but couldn't help asking: "Chao, how about you?"

Chao Lingyin turned around and smiled, "I'm going to prepare a secret weapon."

...In the atrium of Sky Castle, at this moment, all the girls except Misaka Mikoto's are gathered together. Rin Tohsaka put down the communicator, looked at the people around him, his face was extremely heavy, "Everyone heard clearly, this time the enemy's coming is beyond imagination, but there is only one thing we can do...to meet the enemy!"

Everyone nodded in unison. Although some girls with weak surnames had faint fear in their eyes, none of them flinched. As Tohsaka Rin said before, this is their world and must be protected!

Among these girls, Tohsaka Rin is not the strongest, nor the smartest, but she is the first to follow Lin Luo, and also the one who has experienced the most in the battle of gods. Although usually everyone will not live under this arrogant modern mechanical idiot who can't even "flexibly" use a mobile phone, but at this critical moment of life and death, she still has a certain right to speak.

A war cannot be fought without a leader. At this moment, Lin Luo and Ewen Jielin are not here, so this burden can only fall on her. Although Nero was the king of Rome during her lifetime, her character was not suitable for leadership, and she did not deliberately fight for this position.

In a large-scale war, Tohsaka Rin may not be able to do it, but in a battle with a few or even a dozen people, her opinions can still convince everyone. As for the bad habit of making mistakes at critical moments, others will naturally correct it... That is cc.

So, with Tohsaka Rin as the commander-in-chief and cc as the military adviser, the two are in charge of the local battle command, while Chao Lingyin sits in the city of the sky and defends from the overall perspective... The girls' first world defense battle begins!

This is the first time, and it may be the last time!

Under the command of Tohsaka Rin, everyone's division of labor is very clear. First of all, Black Rock Shooter and Black Saber formed a team, and at the same time, Yan Ye led a hundred mechanical maids equipped with special Gundams, including her, to resist the undead enemies head-on. Although it is said to be undead, it is actually just some skeleton soldiers. Once broken, it is impossible to resurrect, so even technology weapons can have an effect, and Black Rock's fire attack and black saber's light attack can cause huge damage to undead.

Secondly, a team consisting of Mugino Shirley and Shokuhou Misaki, together with a hundred maids equipped with Gundams also led by Jiu Yuan, resisted the army of monsters from the rear. For biological enemies, the abilities of the two of them are quite suitable. Not to mention Mugino Shitoshi's atomic collapse and the power of fallen angels, the mind control of Shokuhou Chichi alone can achieve the effect of instigating rebellion, but the enemies of the advanced spiritual rank may be difficult to deal with.

In the end, Isayama Koizumi and Tumiya Kagura form a team to resist the ghost army attacking from the right. Both of them are experts in removing spirits. Naturally, they are the best at dealing with this type of enemy. Wei Kinoka and Sakura Saki Setsuna are a team of healers and guards, just in case.

Tohsaka Rin needs to observe the whole venue in order to make timely investigations, and cannot attack directly, so he stays in the atrium temporarily. Of course, the same is true for CC as a military adviser, and it is impossible for Ravelly to fight head-on. The commander-in-chief's flag cannot fall, and as guards, fifty mechanical maids equipped with Gundams are left in the atrium for protection.

The only remaining little Saber and Wei led the remaining 50 mechanical maids to the left to support the Dragon Clan. Although the Dragon Clan has a large number of people, the number of enemies is even greater. It is almost impossible to stop the dozen or so spiritual peak powerhouses.

After the battle team was configured, before they set off, Rin Tohsaka pointed out solemnly that if they were unable to resist, they would retreat to Sky City, which was their last line of defense. Although Sky City can defend against any attack below the ground level, in theory, as long as they hide in Sky City, nothing will happen, but!

After all, the theory is just a theory. After the test by Chao Lingyin, the defense of the Sky City against the peak of the spiritual rank is not absolute. Maybe one or two can't break through the Sky City, but if there are more than one, it will be dangerous, and...God knows whether there will be other enemies in the future besides the ones in front of them.

In fact, they were lucky this time, because the enemy appeared far away, and the timely alarm gave them such a little time to prepare. Otherwise, if the enemy directly parachuted into the sky city, facing such a large number, they would have no other way to deal with it except to hide in the main hall.

Of course, in fact, this is not luck, but the home field advantage of the king of the world. In order to avoid such things as sudden attacks, it is impossible for invaders who travel to this world to directly reach the center of the world, but at least a hundred miles away. This is also a kind of balance in the battle of gods.

Watching the girls leave one by one, Tohsaka Rin didn't show any excitement, but frowned.

"Don't be too nervous, this configuration is the most correct so far, you've done a good job." Seeing her expression, cc couldn't help saying, with admiration in his tone. To be honest, she was really a little surprised. When she decided to let Tohsaka Rin be the commander-in-chief of this battle, she herself did not expect that this usually arrogant girl would show such a strong and decisive side. Although there are some deficiencies in some places, her excellent commanding ability is fully displayed, and she is calm and able to analyze details, which is quite rare at such an age.

"But the difference is too much." Tohsaka Rin shook his head and smiled wryly. Although all the available combat power has been used, the overall strength and personal combat power are too different from the enemy, and there is almost no possibility of victory. It is more like death than resistance. If it weren't for the space jumping device with super bell sound, she would not dare to send so many companions to such a dangerous battlefield.

In fact, Tohsaka Rin didn't know that most of the invaders this time were blocked from the world by the troops sent by the Dark King, and the two armies were in a state of fierce confrontation, otherwise what they would have to face would not be these spirit-level enemies, but the irresistible earth-level powerhouses!

At that time, even if they hid in the city of the sky, it was useless, there was only one dead end.

Of course, even now, it is still a near-death situation for them!

"I hope the super ring tone can surprise us." Tohsaka Rin frowned and said in a deep voice. She knows that Chaolingyin has a secret weapon, but it is very troublesome to activate it in a short period of time. If they can sustain the activation time, and then use Chaolingyin's secret weapon as the final trump card, it is not impossible to win.

"To defeat the past self, the result of actions will only take a few minutes... I'm still a little uneasy." CC said calmly. Unlike others, as a person who sees through life and death, she will not panic because of the crisis in front of her, although her heart may not really be able to calm down.

Tohsaka Rin smiled bitterly. She knew that the people around her had the temperament of philosophers from the previous relationship, and often said some incomprehensible words. For example, this time, she might still ponder the meaning of the other party's words before, but now... She is not in that mood.

Behind the two of them, Lei Fuli was silent, and she didn't say a word from the beginning to the end, but looking at the enemy who was getting closer and closer in the distance, an inexplicable brilliance flashed in her eyes.

Surrounding them, fifty mechanical maids each sat in a Gundam more than ten meters high, surrounding the three of them, with their huge muzzles facing all around, motionless as if they were still. Although they don't have to directly participate in the battle, their tasks are no easier than others, which puts them under a lot of pressure. Fortunately, they are all robots, and they will not be unable to concentrate.

At this moment, except for the orc troops who had already fought with the dragons, the other invaders were several miles away, but the girls were already ready. In addition to the head-on attack of the black group rushing over at full speed, the super power group and the lily group were standing on the edge of the sky city, and then... "to the bridge of the starry sky!"

Following the girls' shouts, a huge curtain of light stretched out from the edge of the sky city in an instant.

Sky City is floating in the air. Except for the undead army attacking from the front, the Warcraft Legion and Ghost Legion are all air combat units, but not everyone here can fly, and some people are not good at air combat. For this reason, there must be a platform suitable for combat. Chao Lingyin had noticed this a long time ago, so she created a prop that could allow girls to fight in the air not long ago, that is... the bridge of starry sky!

It was a light curtain extending from the city in the sky. As long as they brought corresponding props, when they stepped onto this light curtain, it was no different from stepping on the ground. In this way, even enemies in the air could be dealt with.

The bridge of the starry sky was erected, and the light curtain directly extended nearly 10,000 meters, and the girls rushed towards the enemy in a mighty manner.
