Feeling the danger coming from the underground, Ye Feng's face became more and more difficult to look at.

Obviously, everything is fine now, it is just a appearance, the real crisis has not been resolved, and if the crisis is not resolved, even if they can gain the upper hand now and suppress the tide of corpses, it will be useless.

"What the hell is going on? The danger comes from the underground, but now the zombie rats under the ground have been completely suppressed, why do I still feel dangerous. Ye Feng's brows furrowed into a Sichuan character.

Suddenly, a flash of inspiration flashed in Ye Feng's mind, he seemed to think of something, and couldn't help but pat his head, "Why didn't I think of this." ”

Ye Feng said, and immediately released his spiritual power again, and explored underground.

Soon, the scene of the zombie rat digging the tunnel came to Ye Feng's mind, but Ye Feng's spiritual power at this time did not pause, and continued to explore the past below.

That's right, this is what Ye Feng guessed, these zombie rats generally only move about ten meters underground, and will not continue to go down, which will make people have a misunderstanding, thinking that these zombie rats will only move in this area.

And Ye Feng also fell into this misunderstanding, but now that the seismograph has greatly curbed these zombie rats, but there is still a sense of danger, Ye Feng can only infer that the real layout of these zombie rats is further underground.

The spiritual power continued to probe downward, and soon exceeded 10 meters, 20 meters, and 30 meters...... 50 meters, and when he reached 50 meters, he felt strained.

It's much harder to probe what's underground, and it's at least ten times more difficult.

Therefore, Ye Feng's spiritual power could have explored a place 500 meters away, but underground, it was a bit difficult to explore only about 50 meters.

However, of course, Ye Feng would not give up just yet, but immediately manipulated his spiritual power to condense into a bundle and continued to probe downward in a single direction.

60 meters, 70 meters...... 100 meters, in the blink of an eye, Ye Feng's spiritual power probed to a depth of hundreds of meters, but at such a depth, he still couldn't detect anything, except for dirt and rocks.

But Ye Feng's spiritual power was close to the limit again, which couldn't help but make him frown.

You know, it's 100 meters deep underground, which is already quite terrifying, and it is difficult for ordinary drilling rigs to reach this depth, and there are basically not many microorganisms.

Even Ye Feng began to wonder if his guess was correct.

However, recalling the feeling of the spiritual power, he finally gritted his teeth and urged the spiritual power to run at high speed with all his strength, and he instantly entered an ethereal state.

The ethereal state is a special ability that naturally arises after Ye Feng's spiritual power reaches the limit of the human body, this ability Ye Feng rarely uses it, but it does not mean that it is not strong, on the contrary, this kind of ability produced by the human body after reaching the limit is powerful and terrifying.

And this ability also has the ability to grow, and can grow with its own growth.

At this time, after Ye Feng entered the ethereal state, it seemed that the whole world had slowed down, and his facial features were extremely sharp, and his mental power in his mind was extremely active.

At this moment, Ye Feng had an illusion, as if he was the god of this world at this time, and he could see everything in a single thought.

Of course, Ye Feng also knew that this was just his illusion, so he quickly calmed down, and then urged the surging spiritual power to continue to probe downward.

Perhaps because of the ethereal state, in this special state, Ye Feng's sense of danger became more and more keen, not only being able to determine that the danger was coming from underground, but even the general direction.

Ye Feng immediately did not hesitate, his spiritual power probed in the direction he felt, and soon went deep into the ground hundreds of meters, and then continued to explore, 110 meters, 130 meters, 150 meters, 180 meters, and in the blink of an eye, Ye Feng's spiritual power probed to a depth of nearly 200 meters.

At this point, his spiritual power was close to the limit again, but in Ye Feng's perception, he was already very close to the danger.

"Fight!" Ye Feng gritted his teeth fiercely, urging his spiritual power to the limit, and there was a sudden feeling of pain in his mind.

Under such pain, Ye Feng's spiritual power continued to extend downward, 201 meters, 203 meters, and 205 meters. In the end, when Ye Feng's spiritual power probed to a depth of 210 meters, he suddenly felt that the resistance in front of him disappeared in an instant.

And his spiritual power entered an open place.

At first glance, it looks like a huge cave, at least twenty or thirty football fields in size, and about 50 meters high.

Of course, if that's all there is, that's fine, but the problem is that in this huge cavern underground, there are dense zombie rats still digging this cave, and the number is at least more than 100 million.

After discovering this scene, Ye Feng's face changed completely, he finally knew what the other party wanted to do, if he hadn't discovered it in advance, I am afraid that after the other party's plan succeeded, let alone the Yunqing City base, even the entire Human Rejuvenation Alliance, would not be able to escape the fate of being destroyed.

Just as Ye Feng wanted to thoroughly explore this cave and learn more about it, he felt a wave of dizziness in his mind, and he instantly withdrew from the ethereal state, and even the spiritual power released was uncontrollably withdrawn from his mind.

Ye Feng knew that this was caused by the excessive consumption of spiritual power, although the time he spent exploring was less than 20 seconds, the huge spiritual power in his mind was almost exhausted.

When his spiritual power returned, Ye Feng's eyes were dark, and he almost fainted directly, but the reason in his mind told him that he must not faint at this time.

Forcibly biting the tip of his tongue, under the stimulation of pain, Ye Fengqiang cheered up, took out a bottle of blue liquid from the evolution box, pulled out the cap and drank it directly.

As this blue liquid entered the throat, a cool feeling poured into my mind, and a lot of dizziness was immediately relieved.

This immediate effect made Ye Feng secretly sigh, this kind of spiritual power restoration medicine researched by the Chinese Academy of Sciences is really powerful.

After breathing a sigh of relief, Ye Feng didn't care about continuing to recover, but stood up with his body strong, directly opened the curtain of the tent and walked out.

At this time, the bird zombies outside had dispersed, and the speed of the zombie attack outside the city wall had slowed down, coupled with the solution to the problem of zombie rat attacks, all the soldiers had smiles on their faces.

These people gathered in twos and threes to talk, and from time to time there was a hearty laugh.

Xu Youcai and several other high-level executives also gathered together to talk, watching the situation at the base instantly improve, they also had smiles on their faces.

However, during their conversation, they would glance at this place from time to time, wondering why Ye Feng hadn't come out now.

Finally, Ye Feng's door curtain was lifted and he walked out of it, but when everyone saw Ye Feng's pale face, their faces couldn't help but change.
