At the entrance of this steel essence mine, an access control has been set up, and Yu Tian is the director of the East College of Tianjiao Academy, so he naturally has the permission to enter. Pen "Fun" Pavilion www.biquge.info

Entering the Iron Essence Mine, it is pitch black all around, but the sound of running water can be heard, indicating that there is an underground river below.

"Suck it, I'll give you the wind, if the rest of the academy knows, I'll be a sinner for the ages." Yu Tian took out a strong flashlight, shone it around, and said a little nervously.

With the strong light of the flashlight, Wu Mo also saw the pattern in the mine clearly, there was a long tunnel in front, and the sound of flowing water came from the front, and vaguely, Wu Mo saw an iron gate at the end of the tunnel.

"Elder Yu, let's go a little further inside, the more you go inside, the purer the steel essence will definitely be." Wu Mo said with some curiosity.

"The steel essence here is enough for you to suck, there is the lower part of Death Valley, there is a strange energy fluctuation, it will be dangerous to enter, you better not fight the idea of the things in there." Yu Tian said seriously.

Wu Mo took a deep look at the end of the tunnel again, found Yu Tian and took a flashlight, and began to absorb the essence of steel near the entrance of the cave.

The number of steel essences on both sides of this tunnel is not very large, the more steel essence will be there when you go inside, although Yu Tian guessed that Wu Mo's speed of absorbing steel essence will be much faster than ordinary people, but now he saw it with his own eyes, he was almost so surprised that his jaw fell to the ground, Wu Mo's speed of absorbing steel essence was not much faster than ordinary people, but much faster, many, so much that Yu Tian's mouth couldn't close.

This steel essence mine of Tianjiao Academy has existed for more than two hundred years, and for those Tianjiao Academy students who have steel genes and perform well, Tianjiao Academy will allow them to come in and absorb the steel essence here for a few hours.

Yu Tian originally thought that the steel essence near the entrance of this cave would be enough for Wu Mo to absorb, but looking at the current situation, the steel essence in this entire steel essence mine didn't know if it was enough for Wu Mo to absorb.

Yu Tian's heart was a little weak, if this steel essence was absorbed a little, no one should notice it, but if it was absorbed too much, or even all of it, what could it do? I can't explain it to the academy myself.

"Wu Mo, it's almost." Yu Tian said.

"It's rare to come once, you just let me have a good time." Wu Mo smiled, and had no intention of giving up absorption.

Yu Tian was helpless, thinking in his heart, let Wu Mo absorb it for a while, wait a while, Wu Mo still doesn't stop, even if he ties up Wu Mo, he will take him away.

Yu Tian was thinking in his heart, and suddenly there was a sound of "click" breaking in the cave, and before Yu Tian could react, he heard a "boom", and the mountain rock collapsed, directly blocking the entire tunnel, these are ordinary stones, Wu Mo can't absorb them.

Yu Tian looked at the boulder blocked between him and Wu Mo, it was tight, and he could vaguely hear the sound of collapse inside, and his heart was very anxious.

"The power of an elephant." Yu Tian let out a low roar, and a momentum suddenly surged around, and where the momentum passed, the boulder shattered and dust flew.

Although the power of the brute elephant is only an animal gene, once the strength reaches the level of a general, it can turn the invisible power into a tangible force and form a shock wave.

When the dust settled, a passage of more than ten meters appeared at the collapse, but Wu Mo was still not seen.

Yu Tian once again used the power of the brute elephant, this time he could only open up a passage of about five meters, when Yu Tian used the power of the brute elephant for the third time, he could only barely open up a three-meter aisle, the more he went inside, the boulder was mixed with the steel essence, the hardness of the steel essence was too strong, and even the power of Yu Tian's brute elephant was difficult to shake and shatter.

At this time, as the tunnel collapsed, Wu Mo could only retreat deeper.

When he retreated roughly half the distance to the tunnel, the collapse stopped, and Wu Mo's heart was slightly lowered, just looking at the messy boulders in front of him blocking the exit, Wu Mo was a little heartbroken, he wouldn't be so unlucky, if he died here, it would be too embarrassing.

But now this is also a bit beneficial, that is, the steel essence in this Wu Mo can be absorbed casually, Yu Tian can't manage it if he wants to, and this time the movement is so big, Tianjiao Academy will definitely find out, since it will definitely be discovered, then simply absorb it, but the steel essence on both sides of this tunnel, Wu Mo doesn't dare to absorb it anymore, Wu Mo still expects to turn around and go out from here.

Yu Tian said that the end of the tunnel is under the valley of death, and there are dangerous energy fluctuations, Wu Mo took the flashlight and shone towards the end of the tunnel, his curiosity was aroused, Death Valley has always been rumored to be so mysterious, what is the secret?

Although he was a little apprehensive in his heart, in the end, his curiosity outweighed his uneasiness, and Wu Mo decided to go to the end of the tunnel to have a look.

"It's just going to take a look, it shouldn't be dangerous, right?" Wu Mo comforted himself as he walked.

"Don't worry, there are indeed special energy fluctuations in front, but this kind of energy fluctuations will definitely not do any harm to you, your physique is not the physique of ordinary earthlings now." Seeing Wu Mo walking slowly, Oplai couldn't help but say.

Although Oplai has no form now, his perception of the outside world is quite keen, the further he goes, the more Oplai feels a powerful energy, this energy, makes Oplai a little excited, if Wu Mo can get this powerful energy, then Wu Mo's strength will undergo a qualitative change.
