Abyss invasion? As a demon cultivator, I laughed.

This thought made Chu Xiu frown slightly.

This is not a good sign.

Chu Xiu did not believe in coincidences. He had a vague premonition that when the last day came, some unexpected changes might happen.

"Forget it, no matter what happens at that time, I only need to do one thing, that is, to do my best to improve my strength."

Without thinking any more, Chu Xiu slid down all the way and came to the room he had prepared before.

Just like yesterday, he went out carefully, hunted a black-haired corpse ghost, and immediately returned after causing enough noise, relying on favorable terrain to fight.

However, perhaps because he killed a large number of corpse ghosts yesterday, the number of corpse ghosts attracted this time was much less.

After the battle, only eleven black-haired corpse ghosts were killed, and 134 experience and 25 causal points were gained, which was only half of yesterday.

"After all, it is the real world, there is no monster cave with infinite monsters, and these corpse ghosts are also one less each time they are killed." Chu Xiu sighed.

Fortunately, the materials needed to upgrade the bone spear are much smaller than those for the bone armor. These eleven black-haired corpse ghosts have successfully piled it up to +6 reinforcement, making it even sharper.

Moreover, the progress of the practice of the Thirsty Blood Refining Heart Technique has finally slowly climbed to nearly one-third.

However, the speed of practice is getting slower and slower, which is obviously due to the lack of life essence. If you want to make a breakthrough, you may have to kill high-level corpse ghosts or awakeners.

"So, what should we do next?" Chu Xiu fell into thinking.

If we move forward to the lower floors of the apartment building, there must be a large number of corpse ghosts. Apart from anything else, just looking out the window, there are 20 to 30 corpse ghosts visible to the naked eye near the apartment building.

But the problem is that the life-saving device he made with the climbing rope is only long enough to extend to the twenty-first floor.

Going down further, there is no insurance.

"If we encounter an elite like last time, it will be troublesome."

Although Chu Xiu currently has these two Yin ghosts to protect him and +7 energy-absorbing heavy armor, there are still countless variables when facing elite monsters.

"The most important thing is that there is a high probability that there is more than one elite."

Yesterday, he attracted an elite on the twenty-first floor. Excluding the possibility that he has a particularly bad character, the more reasonable explanation is that the density of elite monsters at night is not small!

"Let's be more cautious."

Chu Xiu did not go downstairs in person, but remotely commanded the ghosts to hunt the lone corpse ghosts.

As a development-type [MAX]-level profession, he did not need to be so aggressive.

Finally, after killing five corpse ghosts, two of the ghosts were injured to varying degrees and their status declined. Chu Xiu stopped hunting and returned upstairs, took out several large pieces of wild boar meat to eat, and began to rest and recover his strength.

The next day, he continued hunting as usual.

The harvest was not much, and nine ordinary corpse ghosts were killed in the morning.

It can only be said that the judgment of the people in the base was not groundless. Without Yunlu, it was difficult for him to accurately locate the location of the corpse ghosts. As the density of the surrounding corpse ghosts continued to decrease, his hunting efficiency would also be greatly reduced.

Chu Xiu, who realized this, decided to expand the scope of exploration.

Now, except for the parking lot, the three communities near the apartment building have almost been brushed by him, so he can only continue to explore outside.

He didn't find too many corpse ghosts, but he found traces of two other awakened people.

The awakened people's teleportation is generally gathered in the form of teleportation points. For example, the awakened people within a radius of one mile nearby are basically teleported to the apartment.

This means that there are two teleportation points not too far away from them.

The good news is that they may be used when they continue to explore in the future, and the bad news is that those conspicuous and easy-to-obtain experience treasures have naturally been taken by others.

This made Chu Xiu a little irritated.

"Is it time to start the adventure?" He thought silently.

It's the fifth day since I came to the abyss, and the easy-to-obtain experience has almost been brushed.

Chu Xiu has two choices for a wave of fat. One is to go down to the lower floors at night, or even leave the apartment building directly to join the wild hunt at night. The second is to enter the underground parking lot during the day and raid the nest where the corpse ghosts hide and rest.

Both were extremely risky. After thinking carefully, he still shook his head with a smile.

He lowered his body and quickly moved through the residential buildings, treating the boring and repetitive search work as a kind of training.

To hone his mentality and combat skills.

And perhaps it was a reward from God. When the sun was about to set, he finally found a small group of zombies hunting together and killed a total of 17 ordinary zombies at once!

Counting these, he killed a total of 32 zombies today, which brought him 195 professional experience points and 89 causal points.

With so many zombies, he finally succeeded in strengthening the bone spear to +7!

[Exquisite Bone Spear +7]

[Strengthening Progress: 0/10]

[Level: Ordinary]

[Quality: Excellent]

[Attributes: Solid (2.8), Sharp (3.4), Bleeding (1.9), Weight 3.5kg]

[Now you can choose the second level of restrictions to be engraved. 】

[Armor-piercing: A special spiritual structure that can make the tip of the spear form a high-speed vibrating film, greatly improving the armor-piercing ability (sharpness +1.8)]

[Explosion: Explosion restriction, which can make every attack of yours come with an additional explosion damage (power: 2.0)]

[Bloodsucking: Now when your bone spear pierces the enemy, it can continuously extract the opponent's vitality to heal its own injuries and increase its strength and vitality to a certain extent (absorption: 1.4)]

It was another familiar choice of three.

However, this time Chu Xiu did not hesitate at all and chose [Armor Piercing].

The reason is also very simple. This is the enhancement of basic attributes. The higher his physique, the better the effect, and the more suitable it is for future battles.

The other two can only play a role of icing on the cake.

"Of course, if you want to maximize the effect, you still have to wait until you reach level 6 and then refine the Thirsty Blood Refining Heart Technique."

"By then, you will have the confidence to take slightly more radical actions."

"You have to keep working hard!"

Back at the base, Shen Zhuo and others were still as usual and had come back to rest early.

They were also very happy today, gathered in the room and laughed, and obviously gained a lot. When Shen Zhuo came to Chu Xiu to upgrade his equipment later, he knew that they had killed nearly fifty corpse ghosts today, a little more than him.

It seems that everything is moving in a good direction.

Chu Xiu received 98 karma points and helped them strengthen again.

Everyone was very satisfied, but Chu Xiu noticed that after receiving the enhanced equipment, Li Shan and Wang Long looked at him with more greed.

Chu Xiu knew what was going on. After everyone left, he ate a few pieces of meat to restore his strength, and then continued to level up without stopping.

He killed thirteen black-haired corpse ghosts in one night, and a total of twenty-two in the next day.

Hunting efficiency continued to decline.

Fortunately, Chu Xiu's hard work paid off.

These corpses allowed Chu Xiu's white bone ghost banner to reach +6, further expanding its capacity and refining a third ghost.

Although it was only level 7 of the ordinary rank, it undoubtedly further improved Chu Xiu's strength.

At the same time, it also brought him 59 karma points and a [ordinary] quality weapon that he could not use.

And most importantly, after so many days of precipitation, his level finally increased again!

[Level Up! ]

[Current Level: Level 6 of the Ordinary Rank]

[A new inheritance has been unlocked. 】
