A few feets underneath the soil, David couldn't see a thing as it was completely dark with no lights coming through but he wasn't hoping for that anyways.
Even the illumination coming from his holographic image was of little to no help at all.
Oscillating every part of his muscles except those at his feet, the surrounding soil disintegrated into dust.
David had only 8 seconds left before his stamina drains.
Stomping his foot against the ground, his figure was like a phantom as he dash through the ground like a fish swimming in the river.
There was little resistance on his way and as soon as the rocks came into contact with his skin, they disintegrate to dust, the resistance they provided was just a little bit greater than the air resistance.
Which meant his speed underneath the ground was only a bit slower than on land.
Using this opportunity, David dashed through the ground like a soil.
In the large hall, David had previously noticed that a few mountain rock were different from the others in the surrounding area.
Which made David suspect that the rocks and sand in that position had disintegrated countless number of times and then had reformed back to their original structure.
Using his motion technique, David was like a spectra as he rushed through the ground like a phantom.
The ground continued to release muffled booms as David tried to search the entire area under the large building.
Just a few seconds after, as sudden sound startled him.
Dong!
It seems his leg had hit something metallic.
'Found it!' David's eyes lit up in glee.
Dispersing the undulations emanating from his body, David bent his body down.
Turning on the emergency lights, he knelt down and used his hands to sweep off the remaining sand covering the metallic surface he saw.
Sweat mixed with sand and dust dripped down his forehead onto the silver metallic surface that had been illuminated from the lights coming from the chip imbedded in his wrist.
(If you remember, a micro chip had been inserted to ecey students of the institute during the implantation process which is also where the AI had been installed with.)
Using his fingers, he flicked at the metal, trying to figure the thickness and the hardness of the metal.
Soon, his head furrowed into a frown. It was going to be very difficult to get through the steel wall.
His head was also getting a bit lighter since the oxygen in the atmosphere was extremely thin.
As a Spryher, he needed more oxygen than an average human. Unless he learnt a technique to store and hold in more oxygen into his body, it was practically impossible to hold his breath more than an average human being.
After a while, his eyes hardened and determination shone in them.
The muscles in his right hand suddenly expanded and the veins on his hands throbbed madly.
His hands currently, doesn't look one bit human. It was as if he had a monster in his body which it's hands had been revealed.
Clenching his fist, a crackle exploded in between his hands.
And without any formalities, he punched down at the metallic surface in a lightning quick manner.
Boom!
With a ear-splitting explosion, David's body trembled and he was softly pushed backwards by the rebounding force.
David's face suddenly darkened. The metallic surface only showed a small depression on its surface.
Despite activating Three-Fold strength shortly, he could onlyake a small depression on the metal surface.
This made him very depressed. There was another way to enter the hidden cave or room.
That was to search the hole the Land Shark used in passing through to the other side but that would require him to activate Earth Swim for an extended period of time.
And it would also require time which he really doesn't have right now. He was about to suffocate to death.
He head was really getting lighter, he was feeling dizzy and his eyes were starting to sting.
He was in a desperate situation right now and there was only two options left for him to do.
He either have to go back up to get more oxygen or continue to pound through the metallic surface until it gave out.
Either way, he had to make a decision very soon as he had only a few seconds left.
Gritting his teeth, his eyes bloodshot, he flexed his muscles tightly and his hands which was previously three times its previous size compressed like a deflated balloon.
Suddenly, his muscles compressed tightly and the contours of his body was on full display. Not a single bone could be seen.
Only strongly tempered muscles could be seen and his skin shine a bronze color as though they were made of metals themselves.
As soon as his two hands hardened into a bronze color, he suddenly started pummelling the metal surface like it had killed his wife or something.
Boom! Boom! Boom!
The soil around his body has solidified since his body has stopped undulating the unique frequency.
There was no way the booming sounds could escape to except his ears but David wasn't in the right state of mind to sarvor them.
The power around his fist suddenly turned berserk and the temperature in the tiny cave he had made instantly increased in temperature.
Formless Heat!
And as if that wasn't enough,
Scorching Fury!
Heat blasted through his face, drying up the sweat in the area. The heat was Formless but powerful.
Invisible but yet consistent.
Bang! Bang! Bang!
Just like a small cannon, his fist rampage through the steel wall like a mad ape.
The wall continued to cave in but didn't give in. But as soon as he punched with his Formless heat, the walls caved in massively, turning red but still didn't give in.
It even showed signs of recovering to its previous size.
It seems like the metal used to guard the room or cave has an elastic property.
But David was far too gone, he was already unconscious but it was like he had another consciousness in his body as his fists continued punching through the walls.
In a blink of an eye, the metal wall gave a crack and his right hand suddenly came out from the other side of the wall.
