Tower Defense Game: My Kingdom of Eternal Life

It's actually a rare set part.

Cheng Shen became interested.

Being able to explode one of them means that the Library Book Demon can also explode other parts of the Abyss Surge.

The probability is low though.

But after the place is completely opened, according to the missionary's information, you will have the authority to open the dungeon at any time. By then, even if you can't get it out once or twice, you can always collect the remaining parts over time.

"You put it on first."

Cheng Shen gave the robe to the rat mage.

Once covered with a gray robe, its figure was immediately hidden, giving it a sense of mystery, except that its two skinny legs would be exposed from time to time when walking.

Cheng Shen then checked around to make sure there were no books that could be read. At the same time, he also discovered that there was no other exit in the huge library. The only way forward was the underground entrance that was opened.

The cave is cold and cold, and the passage slopes downward, allowing five people to walk side by side at the same time. The floor is paved with gray stone bricks, and the walls on both sides are inlaid with pieces of crystal-like material, emitting a faint blue light.

"Go down and have a look."

Cheng Shen said to Da Meng.

"Yes, sir!"

Da Meng jumped down without any hesitation, and advanced for more than ten meters under Cheng Shen's gaze. He did not encounter any trap, and the others followed suit.

Ta, tap,...

The footsteps of the team echoed in the deep passage, reaching far away. No one spoke, and it was so quiet that one could hear the heartbeat.

Cheng Shen took a moment to look at the task list.

in.

The first mission of destroying all alienated objects has been completed.

It probably means that all the monsters the Book Demon has encountered before, including the puppets in the first level, have signs of being affected by magic energy. After destroying them, you will have completed the regular dungeon challenge and can receive rewards.

The 100% dungeon reward is a rare treasure chest, which can unlock one of the rare items produced in the dungeon.

Plus experience points,

and some gold coins.

Cheng Shen calculated that he would be able to reach level 17 after leaving.

The experience gained by upgrading survivors and recruited units increases gradually. Unlike defense towers, the experience points required at each stage are fixed.

He now needs more than 20,000 experience points per level.

And it's getting slower and slower.

Tick...

There was a faint sound of dripping water ahead.

Gradually it becomes clear.

The passage soon came to an end.

This is a man-made cave. It is very wide and is as big as two or three football fields combined. Above the cave, there are densely-formed stalactite pillars hanging down like a stone forest.

Magical energy so rich that it is visible to the naked eye covers these stone pillars, and drops of crystal blue liquid drip from the tips of the pillars.

During the dripping process, most of the liquid will evaporate, and only a small amount will fall to the ground, accumulating into blue puddles as big as a palm.

The crystal light at the bottom of the pit flashed.

After Cheng Shen saw clearly what was inside, his breathing became rapid.

Those are actually energy crystals!

"This place...is indeed an energy crystallization vein!"

He was shocked to the bottom of his heart.

Outside, the only way for survivors to obtain primary energy crystals is through the resource packs rewarded by defense. After five waves, some can be found in the grocery store built, but the number is extremely limited.

But at this moment, when he looked at it, he could see at least hundreds of energy crystals!

Such abundant resources made him jealous!

"The missionary said that if you clear the dungeon, you can gain ownership of a resource point. Could it be that the resource point that pollutes the library is this energy crystal vein?! This is a huge profit..."

Cheng Shen quickly calmed down.

This place doesn't belong to me yet, and there are still two main tasks that have not been completed.

One of them also needs to kill the evil mage, the final boss of the dungeon.

It is not time to take things lightly.

He looked up and saw that in his field of vision, the cave was completely filled with dark blue energy, and there were almost no traces of the existence of other elements, but this made him no longer have to worry about elemental chaos.

Pure magic makes this area extremely stable.

"Magic energy should also belong to the category of energy. I wonder if I can control magic energy to perform magic..."

Cheng Shen suddenly had an idea.

He immediately dispersed a burst of mental power and touched the magic energy in the air. As soon as he made contact, a strange and stagnant feeling appeared in his mind.

The mental power slowly moved a ray of magic energy.

But his mana was consumed at nearly five times the usual speed.

Cheng Shen immediately stopped trying.

"It can be sensed, but it is difficult to control. It is far from as easy as controlling ordinary elements... Is it because the level of energy control is not enough?"

Cheng Shen glanced at the skill bar.

He has been using energy control almost every moment since he learned it, but his proficiency has progressed very slowly. It is a talent and cannot be improved with skill points, so he can only rely on himself to slowly use it and practice it.

"Being able to control it means that the effect of the talent is being exerted, so there is a high probability that the talent level is not enough."

Cheng Shen couldn't help but be curious.

"Is there still levels of energy?"

In his understanding, the intensity of energy is a matter of the amount of energy gathered.

Now it seems that this idea of ​​his is about to be completely overturned.

"It's really no good if you haven't experienced systematic learning. It's a pity that Lawrence is also a dabbler...sigh."

Cheng Shen stopped for a moment, then switched to the bright red form and walked forward.

Since elemental energy cannot be sensed in the air, his magical abilities will be greatly weakened. At this time, the bright red form will come in handy.

As soon as he switched forms, his blood volume immediately soared to 12,000 points, which was even higher than Da Meng's tankiness. Naturally, there was no need to continue hiding behind.

Walking to the center of the cave, Cheng Shen saw a bottomless pit with a diameter of one meter. Condensed magic energy continued to erupt from the pit, and pieces of energy crystals were formed around the edges. Cheng Shen's eyes glowed when he saw it.

.

"This is the source of the leakage of magic energy."

He judged it at a glance.

It is precisely because of the constant spewing of magic energy from this deep pit that the magic energy here will always exist. As long as we find a way to plug this big pit, the impact of the leakage will gradually diminish until it returns to normal.

"Is it blocked..."

Cheng Shen's thoughts were spinning.

In fact, monsters born from the alienation of magic energy are also one of the resources produced in this copy.

Not to mention the materials.

The experience alone is a considerable benefit.

If this hole is blocked and there is no magic influence, will other monsters still spawn?

Cheng Shen felt that the strict logic of the system would definitely prevent it from being used.

and.

The crystal output in the cave also relies on this mysterious entrance.

"It can't be blocked, so the purpose of solving the root cause may be to let yourself use this place..."

Cheng Shen continued to walk forward.

Inside the cave, there was an uneven cave passage. After walking about a hundred meters, a huge space appeared in front of Cheng Shen. A shocking scene suddenly hit his field of vision. There was a dragon entrenched in the space!

A lifelike blue dragon with a body length of hundreds of meters and dense steel scales all over its body!

The giant dragon's eyes were open, revealing a pair of clear yellow eyes, its huge mouth was slightly open, and its teeth were intertwined like sharp knives. It breathed out a cold breath, freezing the ground in front of it into frost.
