"Where?"

The Sword of God was held in his hand, and Zhang Yang looked around. This metal palace is actually quite large, with more than 1,000 square meters, or a 20-story pattern, countless dark passages, and at least more than 300 houses. There is also what does this danger level 30 mean.

"It's 1,000 meters away from the main hall...... You are 1,300 meters away from the commander......" said here. Kolo said again: "It's turning, going down, the speed is 8 meters per second......" After a while, Kolo said: "It's far away from the main hall, the speed is 8 meters per second......"

"Are you gone?" Zhang Yang asked.

"Yes, Commander, you're safe for now, but I suggest you get out of here." Kolo explained: "The lifeforms with a danger of 30 are generally group lifeforms, they generally do not act alone, if there is action, it must be collective action, the lifeform should have been summoned by their leader to go back just now, otherwise he will not let go of the ...... here"

"Why?" Zhang Yang asked.

"With the speed at which it was facing the main hall just now, it was slow first and then fast, and the starting speed was 5 meters per second, which was an ordinary speed, but when it was close to the main hall 1000 meters, the speed became 8 meters per second, which belongs to the acceleration speed, which means that he has discovered the main hall, or rather, he has discovered you in the main hall, so if I am not mistaken, when it comes again, it will lead many similar ......" Kolo analyzed: "Their vital signs should be able to perceive the microwave energy emitted from human beings...... Sensing distance is 1000 m to 2000 m ......"

"Then we ......" Zhang Yang didn't know what to do.

"Commander, our first task is to return to the surface, but the ground is 2,000 kilometers away from here, and it is still full of rocks and mud, so it is impossible in a short time, so we should find the companions you are talking about, that is, the remnants of humanity." Kolo said: "With your understanding of 8,000 years of human civilization, you should be able to lead them out of the ground and welcome the sun......"

"Okay!" Zhang Yang felt that he had no choice.

With Koloe's guidance, Zhang Yang was not afraid of the force that affected the direction instrument, that is, the magnetic field. The magnetic field is extremely unstable underground, or rather moves. Chloe explained that the Earth's magnetic field is affected by millions of planets in the universe, and as long as any two planets or stars are in the same straight line as the Earth, the Earth's magnetic field will increase or weaken, so the Earth's magnetic field is unstable, as if it will move.

But Chloe has awakened, and as long as it wasn't for the influence of a binary-star magnetic field, he would point him in the right direction.

The so-called binary star magnetic field is when two stars are in a straight line with the earth, causing the earth's magnetic field to increase dramatically, and all means of communication will fail.

"This one has no energy, can it move?" Zhang Yang pointed to a car that looked like a broken one.

Kolo said: "It should be able to move, this car also belonged to the tunnel car of the advanced magnetic vehicle series 8,000 years ago, and it can rely on the earth's magnetic energy to move forever." Although the power unit and energy device are broken now, it should move, you try to press the red button......"

Zhang Yang pressed the red button, and in a moment, the magnetic tunnel car made a sound, "Commander, my ability device and energy device have been destroyed, if you want to move, you must find two composite tracks, and a magnetic energy collector, these things should have a lot of ...... in the main hall."

Zhang Yang looked puzzled, and Kolo said: "Find the magnetic energy collector first, he should be somewhere in these 300 houses." ”

The metal hall is 80 meters high, has 20 floors, and has more than 300 rooms.

In order to survive, Zhang Yang also worked hard, turning over in every room. According to Koloe, energy harvesters are everywhere, such as on light bulb circuits, but there is not a single energy harvester in 300 rooms, as if a large hall is being visited by thieves.

"Nope!" Zhang Yang complained that it took three hours to find a magnetic energy collector.

Kolo didn't speak, but after a moment, he said: "At a distance of 1,500 meters from the main hall, there is an energy absorption device, which should be a magnetic energy harvester." ”

"Really!" Zhang Yang was a little excited.

"Yes, but there's a dangerous 30 lifeform in that place, and it hasn't spotted you yet, and if you get close, it will find you." Chloe reminded.

Zhang Yang hesitated for a moment and said, "Are you sure it's one?" At this moment, Zhang Yang had his own idea, that is, to solve the lifeform with a danger of 30 by himself. According to Koloe's explanation, a life form with a danger of 30 is about the same as the combat power of a dog in ancient civilization, and he should be able to deal with it.

"Yes, within 5,000 meters, there's only one lifeform." Collow Road.

"That's good!" Zhang Yang walked 500 meters ahead. He was only 1,500 meters away from the lifeform, and the lifeform had the ability to perceive human microwave energy within a range of 1,000 meters, so as long as it was 1,000 meters away, the lifeform would rush towards him. Sure enough, the creature was moving, and it was moving at a speed of 8 meters per second.

"Commander, the lifeform approaches the main hall in 60 seconds, and then attacks you in 10 seconds." Collow Road.

"I see." Zhang Yang was a little nervous. This is his first time fighting, and he doesn't know what his opponent is like yet.

After 30 seconds, ripples appeared on the surface of the water, and then 2 seconds later, earthworms that were 3 meters long pounced on Zhang Yang. It was indeed an earthworm, but it was really large, with a body as thick as a kettle, and a mouth full of fangs, which was round in shape, and it was estimated that there were 50 of them. Zhang Yang was frightened by the first one.

Bang!

He barely managed to block the giant earthworm's fangs with his sword, and was hit by the giant earthworm's tail. The strength of that tail was very strong, and it was pumped on Zhang Yang's body, directly pumping Zhang Yang away, and falling heavily to the ground, and at the same time, there was a sound of bones 'creaking' on his body.

"Is this the danger level of 30, the combat power of only one dog?" Zhang Yang asked. Although there are very few underground civilized dogs, there are still them, Zhang Yang remembers that when he went to the empire, a dog was easily kicked away, and his combat effectiveness could not be compared with ordinary people at all. But he is already a strengthened person, one person can at least defeat ten ordinary people in the empire, but how can he not be worth a dog, is there any difference between the dog 8,000 years ago and the dog now.

"Yes......" Colo said, "8,000 years ago dogs were all modified, with good attack and defense genes, and at the same time, their IQ has also been greatly improved, and they can make different judgments according to different situations." The giant earthworm in front of you now should also be an experimental earthworm 8,000 years ago, and its IQ cannot be compared with that of ordinary earthworms. Now I've calculated that the probability that you can defeat it is 50%, and the probability of escaping is 20% dead...... The probability of being killed is 80%......"

"Then I'm going to die." Zhang Yang directly defined himself.

"No, you still have a 50% chance of knocking it off, a 20% chance of killing it, and a 20% chance of escaping. But now we urgently need magnetic energy collectors...... You notice that the wounds on its body are not ...... It's healing...... The sword you just used left a scar on the side of his mouth, and according to the vitality of its cells, it would take at least 2 days to heal, but now it heals in less than 10 seconds, so it can only mean that there is a magnetic energy collector in its body...... This is what we have to do, so you have to kill it......"

"Can I do it?" Zhang Yang asked, the probability of being killed is 80%.

"Yes......" Colo said, "I just found out that the combination lock that the former Eighth Commander gave me was unlocked. There are a total of 8 combination locks in this one, and each one requires certain conditions to unlock. One of the first combination locks requires you to encounter an invincible situation......"

"So what should I do now...... Zhang Yang asked.

"Now you close your eyes...... "Kolo said in a mysterious tone, "The contents of the first combination lock are the essence of human civilization 8,000 years ago, and it is a set of body magnetic field control methods, an ability that only a few people can cultivate. If you learn it, you can control the magnetic field in your body, convert the oxygen you inhale into oxygen ions, and then work in your body, do all kinds of acceleration and subtraction, or heat and freeze, and then release it from the pores of your body to attack the enemy. ”

"Is that okay?" Zhang Yang was a little skeptical. But suddenly I felt that my brain received a stream of data, and that data merged with my brain, and then I had an instinctive thought, first of all, I took a casual breath, and that breath accelerated in my body in a strange way.

As the gas moved faster and faster, he instinctively threw a punch at the earthworm. An ordinary punch, before it landed on the earthworm, actually emitted a white light, and then the white fist landed on the giant earthworm, and the earthworm was like made of tofu, and it became two.

"It's dead." Zhang Yang looked at his fist incredulously, feeling like a dream.
