"But first to improve the strength of the Iron Bull, do you go outside to pick up the fragments of the battleship, or go to rob those mutant tribes?" Yang Bo looked at the Iron Bull again, the strength of the Iron Bull is now good B-level, but it is nothing in the entire underground world, and there are many mutants.

Just like today's guy who restrains the Iron Bull, other people's mecha doesn't have metal at all, and the Iron Bull's metal passivation ability doesn't have much effect.

"It's also very dangerous on the ground, and now the alliance fighters on the ground mainly seem to be saving people, not destroying mutants, otherwise they wouldn't turn a blind eye to a large number of mutant fighters." Yang Bo thought that there was no so-called safe area on the ground now, and the outposts of the alliance did not know whether they were evacuated or destroyed, and the facilities in space were also damaged, and it was estimated that they would not be repaired for a while.

"Let's go, Iron Bull, let's go down to the mutant tribe first?" Yang Bo is ready to go to the underground world to train his abilities.

Tie Niu looked at Yang Bo suspiciously, Yang Bo waved his hand at him, it was also a little suspicious, and it didn't understand.

"The egg hurts!" Yang Bo also felt pain when he looked at Tie Niu like this, animals are animals, and he couldn't understand his thoughts at all.

Yang Bo simply let Tie Niu stay here, and then hid out of Tie Niu's cave by himself, and found that there was an unmanned fighter hovering outside.

What Yang Bo didn't know was that the female chief sent a fighter plane to see the mecha here, but unfortunately when the fighter arrived, Yang Bo had already controlled the mecha and hid in the cave.

Later, Yang Bo came out of stealth again, and was not discovered by the fighter, thinking that he was chased to the underground world by this mutant.

There are a lot of small animals on the first floor of the underground world, Yang Bo can know where there are small animals around him with a snap of his fingers, and a half-meter-long lizard in the distance is hiding in a stone crevice.

Yang Bo snapped his fingers again, and the lizard suddenly felt a pain in his brain, and jumped out at once.

Yang Bo was a little embarrassed here, he made a mistake the first time, and then snapped his fingers again, and this time the lizard fell straight to the ground.

"Destroying the central nervous system is faster than destroying the brain." Yang Bo summed it up, the first thing that was destroyed just now was the lizard's brain, but it was not killed all at once, and then the second time it was destroyed, the lizard's central nervous system.

Soon, Yang Bo locked on for a second breath, snapped his fingers again, and this time, the lizard's eyes popped out at once.

"Too much energy." Yang Bo was a little embarrassed again.

Camouflage +1!

"This lizard is still camouflaged, the camouflage is already a great grandmaster, what else is behind?" Yang Bo shook his head, not caring about the information that appeared, maybe this was useless information.

Behind the third lizard, the fourth lizard, from 50 meters to 100 meters, and then again to 150 meters.

At first, the training was all lizards in the open, then lizards hiding in crevices in rocks, and finally lizards hiding behind rocks.

The snapping of fingers in the cave gives people a strange feeling, and the accompanying snapping fingers are dead lizards, lizards are basically the most in this underground world except for mice, lizards also eat mice, and of course rats eat lizards.

Soon Yang Bo found a different lizard, this lizard with a little bit of energy fluctuations, this may be the mutant lizard Yang Bo was more interested, and reached out and snapped his fingers.

This snap finger uses 10 times the energy of the previous snap.

This lizard was nearly two meters long, looking like a crocodile, Yang Bo snapped his fingers, and the eyes on this guy's brain exploded at once.

Camouflage +2!

"E-class mutant beast, is it such rubbish?" Yang Bo came to the lizard and looked at the lizard's miserable appearance.

"It's not a matter to train sonic waves, but to train them to control electrical energy?" Yang Bo felt that he had almost trained the ability of sound waves, and he had not trained much in power control.

As soon as his heart moved, a white lightning bolt appeared in Yang Bo's hand, and this white lightning swam in the palm of his hand, and soon the white lightning became bigger and bigger in his hand, and the color became darker and darker.

Yang Bo looked at the stone a hundred meters away, and then with a wave of his hand, he threw the lightning in his hand over.

In a flash of lightning, lightning fell on the stone.

Boom!

With a bang, the stone was directly blasted into a crack.

Yang Bo's mouth opened wide, he didn't expect that he would have such a strong attack power under his electric control.

So in the next second, Yang Bo spread his hand again, and another lightning appeared in it, this time it was relatively small, and it was thrown out again, at this time Yang Bo thought about this lightning with his mind, but he didn't expect that this lightning really turned towards the place Yang Bo thought of, and landed on a stone next to him.

This time it was much quieter, and it broke a piece on top of the stone.

"It's just a bit of a hassle to store energy?" After the initial test, Yang Bo had a rough idea.

In the next second, Yang Bo stretched out his hand and used his mind to control the lightning in his palm, this time the lightning was gradually deformed under the control of Yang Bo's mind, but Yang Bo felt that it was too difficult to control the appearance of the lightning with his mind, and Yang Bo was originally going to control it into a sword or something else.

After controlling it for a while, the lightning was not very controlled, and finally had to give up and throw the lightning out at once.

Yang Bo found that the distance that lightning thoughts can control can be about a thousand meters, but the farther away it is, the more difficult it is to control, and the amount of thoughts consumed in a thousand meters is 20 times that of 100 meters.

However, the storage of electric energy is a little slow, which is a short board, and it seems that you have to work hard to train for fast energy storage.

Moreover, lightning attacks are easy to be detected by others, and are far less hidden than sound attacks.

The farther the sonic attack goes, the greater the cost, and the energy consumption of a lizard of the same level is about 20 times that of 100 meters at a distance of 100 meters.

After a whole day of training, Yang Bo felt a little tired, so he returned to the Iron Bull Cave and found that the Iron Bull was licking a stone, and this stone had something shiny on it.

Tie Niu saw Yang Bo coming, shook his head and shook it, it was regarded as a greeting, Yang Bo looked carefully at the things that Tie Niu licked, this seems to be a power stone?

So slowly approaching, Tie Niu saw that Yang Bo was interested in this stone, looked at Yang Bo with small eyes, and then pushed the stone with his head.

The stone rolled to Yang Bo's side, and Yang Bo took a closer look, and there were indeed pieces of energy stones on it, with different sizes mixed with the black stones.

Yang Bo touched it with his hand and found that it was really a power stone, and then returned this stone to Tie Niu, and began to ponder in his heart.
