I'm invincible since the end of the world

Looking at the small fortress below, Lin Xinghai asked the fat man on the side: "These should be the teams guarding the abyss passage! Do you know how many troops there are inside?"

He was really curious about this, because if he knew the number of garrison troops, he could actually roughly deduce how dangerous the abyss passage was.

"Uh... they are just the troops stationed in the outer passage. They can only be regarded as reserve troops. Their strength is about 10,000, and the number of mechas among them is about 5,000." The little fat man recalled what his father had said before. replied.

Lin Xinghai couldn't help but inhale slightly. A team of 10,000 people, half of which were mechas, turned out to be just a reserve force.

"Then the real guard troops are underground?" Lin Xinghai guessed.

"Well, I don't know the specific troop deployment," the little fat man replied.

Lin Xinghai fell silent immediately. The danger of this abyss passage was much more terrifying than he initially expected!

At this time, a military transport plane flew over the outer passage. Looking at the dark bottomless pit, everyone on the transport plane felt an indescribable feeling of depression.

Suddenly, a series of roars of artillery fire came from below the passage, and from their angle, they could even see the faint light of fire coming from the dark bottom, but it disappeared in an instant.

"What happened?" Lin Xinghai became slightly nervous.

"There should be another mutated zombie coming out from behind the abyss passage, but the sound of gunfire stopped so quickly. It should be just a small-scale attack that has been resolved." The little fat man guessed.

Although he knew a lot of information, he only heard it from his father. He had never been to the abyss passage in person, so he could only guess about many things.

At this moment, Lin Xinghai seemed to notice something. He looked at the edge of the left passage and his pupils shrank slightly.

There were three "predators" there, climbing up quickly and arriving on the ground in a blink of an eye. After carefully observing their surroundings, they quickly fled.

And these 3 "Predators" are not all, behind them came up again, 3 "Giant Arms", 2 "Spitters" and 1 "Death Claw".

These mutated zombies are very sensitive to danger, so after reaching the ground and sensing the crisis, they almost started running away without hesitation.

Lin Xinghai glanced at the three patrolling groups, but was shocked to find that they seemed to be turning a blind eye to everything in front of them.

Logically speaking, the military must have deployed surveillance equipment nearby, and it is impossible that these mutated zombies would not have been discovered.

Although these patrolling mechas are not in the direction in which the mutant zombies are escaping, if they start to pursue immediately, the three hunters may not be able to catch up, but catching up with the rest of the mutant zombies should not be a big problem.

"What's going on? Why are they watching those mutated zombies escape?" Lin Xinghai asked in a low voice, with some irrepressible anger in his tone.

"Because these are first-level mutated zombies, if the patrol team is nearby, they will definitely kill them easily."

"But if the distance is too far, they will not leave their posts because of a few first-order mutant zombies. For them, what they really have to defend are the second-order and even third-order mutated zombies."

The little fat man explained, seeing that Lin Xinghai's eyes seemed a little blank, and he also knew these situations, which ordinary people did not know, so he continued: "Actually, mutant zombies also have levels."

"The first-level mutant zombies are the mutant zombies we usually encounter. Their strength corresponds to our strong ones in the blood realm."

"On top of this, there are second-level mutated zombies. Their strength corresponds to those of the strong ones in the body shaping realm."

"There are even third-level mutated zombies whose strength corresponds to that of a powerful person in the realm of gods and demons."

"Whether it is the Zhenyuan Guards or these reserve teams, their main job is to prevent those second-level or even third-level mutated zombies from escaping, because as long as one of those emerges, it is likely to cause big trouble."

"As for these first-level mutated zombies, just run away and it won't affect the overall situation."

At this point, the little fat man paused and lowered his voice: "My father said that this should be to increase the sense of urgency in other shelters and to increase their experience in dealing with mutated zombies."

"If one day, a certain abyss passage is lost, the guard team of those shelters will not be confused when they see the mutated zombies."

Lin Xinghai couldn't help but nodded after hearing this. He had to admit that the little fat man's father was right. If you have never fought against mutated zombies, it is difficult to understand how terrifying they are.

"So how strong are the second-level and third-level mutant zombies? Can you tell me in detail?" Lin Xinghai said after a moment of silence.

"Uh... I don't know that either!" The little fat man scratched his head, "I only know their corresponding levels."

"By the way, I also know that mutant zombies of the same level will be much stronger than strong men of the same level."

"For example, warriors in the blood realm cannot defeat first-level mutated zombies. They need to drive mechas."

"As for the strong ones in the Body Shaping Realm and the God and Demon Realm, they can't defeat the mutated zombies of the same level. It is precisely because of this that the 'Rare Mecha' and the 'Legendary Mecha' were born."

"Only by relying on the cooperation of mechas and strong men can we win."

"Is he so powerful?" Lin Xinghai murmured in a low voice. At the same time, he was even more eager for the legendary mecha.

"Don't forget what you promised me. Once you get the spot as a special student, you will build a legendary mecha for me." Lin Xinghai reminded me.

"Yeah!" The little fat man nodded, but after a slight hesitation he added: "But I can't give it to you right away for the legendary mecha. It may take a few months."

"Huh?" Lin Xinghai looked at him, waiting for the other party's explanation.

"The biological alloy used to make the legendary mecha is actually made from the corpses of third-level mutated zombies."

"So we have to wait for the military to kill the third-level mutated zombies, and then my father's company can bid for the purchase and get one for you." The little fat man explained.

Faced with this kind of objectivity problem, Lin Xinghai had no choice. If he didn't have the materials, no matter how hard he pushed the little fat man, he couldn't do it.

However, he also heard another message from the other party's words, "So third-level mutant zombies actually rarely appear, otherwise I wouldn't have to wait a few months."

"That's for sure!" The little fat man nodded, "This is equivalent to the existence of a powerful person in the realm of gods and demons. If it appeared often, we would probably be finished long ago."

"But my dad seemed to have mentioned before that compared to previous years, the frequency of third-level zombies seems to be getting higher and higher. However, here in the East China Sea Base, people are promoted to become powerful gods and demons almost every year. Can handle it.”

After hearing this, Lin Xinghai recalled what Mr. Wei had told him about the secrets of the abyss passage, and an uneasy thought emerged in his mind.

"Little fat man, do you think there will be fourth-level mutant zombies?"
