Doomsday: My Zombies Can Be Synthesized

Further down, the underground passage is slowly narrowing, but it is still more than 20 meters wide, and the density of zombies in the passage is still very high.

Ye Chen joined forces all the way.

This time, it took two days for Ye Chen to synthesize a second-level king-level female zombie, and then another two days for Ye Chen to synthesize a second-level king-level female zombie again.

That is, in four days, Ye Chen merged with a female zombie of the third rank of king rank.

Ye Chen synthesized, all the way down.

Four days later, Ye Chen synthesized a king-level female zombie again.

When the two are combined, Ye Chen has a new king-level 4th-level female zombie.

"The zombies are becoming rarer."

Ye Chen discovered this.

"Should I upgrade Ke'er first, or save it for Zixuan?"

Ye Chen thought.

His original plan for "107" was to advance to Zixuan first, and Ye Chen was not sure about the situation below the passage, but based on the calculation of the zombies that Ye Chen has taken down now, there are more than 10 million at least, close to 20 million. .

What a huge number of zombies!

Ye Chen has been cooperating here for more than a month!

There are so many zombies, but there is not a king-level zombie among them, Ye Chen can't believe it!

Not only the king level, maybe there will be big guys above the middle king, so Ye Chen needs high-end combat power!

"Keep it first! If there are no big guys in the underground, then level up on average. If there are big guys, keep Zixuan!"

Ye Chen made a decision.

Thinking of this, Ye Chen touched Ke'er's head.

In the underground environment, Tongtong and Zixuan's abilities do have some advantages.

"Ker, I will open it for you at one o'clock."

Ke'er shook her head slightly, with the corners of her mouth slightly raised, as if saying that it was okay.

With the current slope, Ye Chen is probably two hundred kilometers away from the surface.

After composing another section, Ye Chen found that the zombies became more and more sparse.

A day later, he found the reason for this sparseness.

There is a big steep slope.

On the steep slope, the zombies were rushing up crazily, but due to the slope, the zombies couldn't rush up densely, and each zombie was at least one meter away from the next zombie.

Ye Chen went all the way down from this steep slope.

The length of this steep slope exceeded his expectations. Ye Chen calculated the distance while synthesizing. After a day and a night, he finally descended to the bottom of the slope.

This day and night, Ye Chen walked down another 100 kilometers at least.

In other words, he is now located three hundred kilometers underground.

At the bottom of the slope, there were still densely packed underground zombies. These zombies were rushing up crazily, but when they saw Ye Chen, they rushed even faster.

"There are more mutant zombies."

Ye Chen obviously felt different.

After half a day, Ye Chen had a new king-level 3rd-level underground female zombie.

The passage is finally over.

A huge underground world appeared in Ye Chen's field of vision. This world was larger and wider than the underground palace, and the end could not be seen with the naked eye.

"My current location should be between 300 and 400 kilometers underground. This place still belongs to the mantle layer and is far from the center of the earth. That is to say, these underground beings live in this space?"

Ye Chen thought.

Although this space is located more than 300 kilometers underground, even an ordinary person can see it clearly.

Because in this world, magma is everywhere.

The magma flowed across, illuminating the whole world brightly.

"So, this world is about to be destroyed by magma, so these underground zombies ran to the ground?"

Ye Chen guessed.

Ye Chen sent No. 2 and an egret.

They go in two directions respectively.

Soon, Ye Chen saw more situations.

There are still many underground zombies, and they are gathering from various places to this passage owned by Ye Chen.

The magma seems to flow everywhere, but there are actually many ways to go.

While synthesizing the zombies, Ye Chen let No. 2 fly towards the direction the zombies came from.

Egrets are hovering in the air.

Ye Chen observed the situation in this space.

"There are some traces of life!"

In the place where the space was not destroyed by magma, Ye Chen saw a large number of low stone houses, and a large number of caves dug down...

The terrain of this space is not flat, there are also many small hills, and almost every hill has densely packed caves.

"It appears that this is indeed where subterranean life lives."

Ye Chen thought.

This space is extraordinarily large, No. 2 has been flying for half a day, but it has not yet reached the end.

Of course, its speed is not fast, because Ye Chen needs it to provide vision, so as to observe this space.

Ye Chen even found a big river in space.

underground river.

This river is at least 100 meters wide, and the water looks very clear. I don't know if there are any living things in it.

While Ye Chen was observing, he continued to synthesize. The underground zombies came continuously, decreasing at a speed visible to the naked eye.

But the quality of zombies is also constantly improving.

Through the vision of the egret, Ye Chen estimated the number of underground zombies that still exist in this space.

There are at most a few million more.

In other words, Ye Chen's benefits are coming to an end.

But the zombies at the back are of really high quality!

Not to mention the mutated zombies, among the zombies below the first level, there are very few low-level ones, and most of them are zombies above the third level.

In less than a day, Ye Chen synthesized a new king-level fourth-level zombie, and when the two combined, Ye Chen obtained a king-level fifth-level zombie.

"Zixuan can be promoted to the sixth rank of king rank."

Ye Chen dragged the king-level 50.5 zombie into Zixuan's grid.

Zixuan has successfully promoted to the sixth rank of King Rank!

Only one step away, you can become the upper king!

But there were not many zombies left in front of Ye Chen.

Although the quality of the zombies is high, there are still no king-level zombies, which makes Ye Chen very puzzled!

"It's strange, these zombies are not human beings, high-level zombies are much faster, why don't they go first?"

"The king-level zombies haven't shown up yet, which is also weird! Could it be that there are so many underground zombies, only the king in the underground king city?"

Ye Chen wondered.
