The virus demon passed through the passage quickly under the leadership of the captain, and they didn't notice that there were two people hiding on the top of the passage.

The virus demon's perception ability has become much stronger after the second mutation, if it were a normal situation, they would definitely be able to sense Mo Fei and Tony who were close at hand, but this time they couldn't sense it at all.

Mo Fei secretly gave Tony a thumbs up, Tony's technology is getting more and more powerful, after Barry and Pete's report, Mo Fei and Tony have small devices on their bodies to shield perception, such instruments make them impossible for virus demons to sense them, so they can't be found.

After the team of virus demons had passed, Murphy and Tony came down from the top and observed the entrance again.

"I'll take a look first and see if there's a loophole to get in." Tony said to Murphy.

These virus demons have been instructed by the upper echelons, because they are all virus demons with no IQ, they are acting like zombies, tireless but very strict in accordance with the requirements of patrolling.

Mo Fei looked at the patrol team of these virus demons and nodded, letting Tony monitor it, and he also directly observed the situation inside in a straight line through the release of his divine sense.

Half an hour later, Tony shook his head at Mo Fei and said, "There are so many patrols here, we can't get in there." ”

"Where's digging a secret passage?" Murphy asked Tony.

"It's not an ordinary difficulty, it is estimated that the secret passage has been dug up before it has been dug out." Tony shook his head again.

Obviously, these mutant virus demons have grown up with some extremely high IQs. Otherwise, there would be no way to distribute these low-level mutant virus demons, and these low-level mutant virus demons are still very mission-executing. Just like a robot, it will perform the task seriously without half a minute of delay and negligence.

"Then let's go up and dig straight down from above." Murphy said to Tony.

It is not necessary to enter this underground space, though. But as in other places, it is estimated that the underground space in other places is heavily guarded, so it is all the same.

Judging from the previous situation when Sword Venom and Reverse Lightning escaped, they entered the underground space nearby, which is probably this position.

"Okay, then let's go up and dig a path and come in." Tony nodded in agreement, he also wanted to find out how these mutant virus demons survived.

After the two cautiously returned to the surface, Murphy and Tony estimated the direction and location they had just taken, and then chose an unnoticed location and began to drill.

Under Mo Fei's sword qi drilling. Soon a small entrance was drilled that could only be passed through by one person, and after Murphy and Tony entered the entrance, they appeared directly in the southeast corner of the underground space.

This location was specially chosen by Mo Fei, and he had previously scanned it through the straight line of his divine sense, and if he entered here, he would not have to worry about being discovered by the mutated virus demon.

"Caves have been dug out here? It seems that even if they become humanoids, there is no way for them to become humans. Tony said, looking at the scene.

"They were originally cultivated by animals." Mo Fei shook his head and said.

Under the influence of viruses and nuclear radiation, they all become more like beasts, and the same also makes them much stronger, almost much stronger than humans.

"Is there anything else we need to see down here?" Tony said after looking at it for a moment.

"Let's go down the next level." Mo Fei said after finding the entrance.

The lower layer is more heavily guarded. Almost all of them are already guarded by medium mutant demons, and if they want to enter, they will probably have to use the previous method.

Choosing an unnoticed location in the corner, Murphy and Tony directly killed the mutant virus demon sleeping deep in it, and then occupied his lair.

"Commencement." Tony glanced at the lair for a few moments before gesturing to Murphy.

Mo Fei nodded. Pointing to the ground, countless sword qi suddenly strangled the soil directly on the ground, directly digging out a passage.

The consolidation of the mutant virus demon in the underground space is also very careful. At the very least, they strengthened the structure of the underground space layer by layer, so that it would not collapse because the structure of the underground space was not strong.

Under Mo Fei's sword qi excavation. Soon the entrance to the passage appeared, and the entrance to such a passage was also very narrow. Only one person can pass through, and because of the narrow entrance of the passage, it is also not easy to be discovered by demons.

"Mo Fei, your ability is too strong, even if you don't become a superhero in the future, being a driller is already very powerful." Tony said with a thumbs up to Mo Fei.

"Your skin is itchy, isn't it?" Mo Fei glared at Tony and said.

Entering the passage, Mo Fei was the first to conduct a divine sense probe from the exit, and soon discovered the gap between the second layer and the first layer, the second layer is full of high-level mutant virus demons, they have formed a complete social system, and there is no sand at all.

"There's another layer down there." Mo Fei saw the entrance to the third layer, which was actually covered with countless high-level mutant virus demons, which made Mo Fei realize that it must not be easy to do so.

"Then let's find a place to dig it down, but I guess the following may be related to the foundation of these mutant virus demons." Tony said, looking at the situation.

There are a lot of demons, which is a bit strange for Tony, can it be said that these demons can still reproduce after being infected and mutated by viruses and nuclear radiation? If that's the case, then their race is just too strong.

"There's no need to explore, there's nothing to explore, I think Sword Venom and Reverse Lightning will probably not climb down even if they get here." Mo Fei shook his head and said.

The purpose of their coming here is to find Sword Venom and Reverse Lightning, if the mutant virus demon does not provoke them, then Mo Fei and Tony do not want to provoke them, of course, the premise is to find a way to open the nuclear radiation energy layer first.

"Where the hell did those two guys go? It stands to reason that there should be nowhere to hide on the island nation, how far can they run? If there was no nuclear radiation energy layer, they would probably run out of the island country, but with that energy layer, they couldn't run out if they wanted to. Tony said, touching his chin.
