The roar of the underground came again, but it was different from the previous loud noise, this time the sound was like the wailing of an old cow when it was dying, weak and painful, accompanied by a hissing sound, Mark didn't know about the underground operation, but he could guess that it was the sound of three drill bits hitting the rock formation, and they had reached the bottom......

However, the power of the splicing drill bit is impossible to break through the walls of the tunnel, and in order for the magma to leak into the mysterious cavity of the thirteenth tunnel, it is necessary to break through the rock wall below and connect the two tunnels.

However, the speed of the drill bit trapped in the magma has been hindered, the power has been greatly reduced, and the high temperature has caused the drill bit material to begin to dissolve......

If the platform is not lowered before the drill bit is completely melted, the whole plan will fail, not only Mark will die here, but the entire equipment will also be destroyed, the world's high-profile future project will be burned, the super drilling will be destroyed in the re-eruption of the volcano, and the progress of human exploration of the center of the earth will return to the original point.

"Damn...... Is that all there is to it......" Mark clenched his fists, his nails digging deep into his palms, he had already come this far, and now let him give up, no matter what, he was not reconciled.

Mark's thoughts exploded in his mind, and at the moment he couldn't tell if it was inspiration or the hallucinations brought on by the heat, but he stepped on the precarious platform frame, and ran on the violently vibrating metal support, which was severely deformed, and was only supported by a row of frames on the side, which was nailed deep into the rock formation, and was torn out more than half of it after the impact, and part of the nail was completely exposed to the air, only the end part was connected to the wall.

It seems that all it takes is one last bit of thrust to push the entire platform.

"Then I'll push it...... Mark rushed to the side of the platform without hesitation, I don't know if it was an illusion, he felt that the ground under his feet was sinking with every step he ran.

He didn't know where he got the strength, he had obviously collapsed when he just climbed up, the high temperature caused a variety of enzymes in the human body to be inactivated, it was difficult for his body to recover, and there was not much energy left in the protective suit...... Mark felt like his skin was being burned, but so what......

I've arrived, I've come here I've gotten here, the last switch...... I'm at my fingertips......

Mark lowered his body and ran forward, his steps began to stagger, but each step was steady, he leaned down and pulled out a piece of metal that was horizontal on the platform, it was originally part of the support, it was two meters long, it should have been destroyed in the explosion, the metal felt hot, maybe because of the pain, Mark felt a twitch in his palm, as if he was slightly electrocuted...... He gathered the last of his strength in that hand and held the iron rod tightly.

"Khooth!" Mark hit the bracket with a heavy blow, and the rock wall that was already overwhelmed shook for a moment, and then a piece of sand and gravel was sprinkled on Mark's face, which was the sand brought out by the fixed nail when it came out of the rock wall, and the rock wall in front of him shattered, as if there was an earth dragon churning and jumping in it, and the nails connected to the rock wall fell off quickly one after another, which may be the most peculiar dominoes in the world.

Mark's final blow became the last straw that crushed the camel, the thrust he brought was quickly amplified, and the chain reaction caused destroyed the final balance of the platform, Mark himself didn't know how he did it, in fact, he made a ghost knock this time to destroy the balance point of the platform, if he deviated a few meters from the side, even if the strength hit several times, he couldn't splash any water, maybe it was luck, maybe it was inspiration, or maybe it was the arrangement in the dark, Mark was right this time.

Only a long, piercing metal whistling sound was heard, and the connection between the platform and the rock wall was completely broken, and the platform was falling rapidly, towards the churning magma sea.

…… ……

The thunderous roar from the depths of the earth turned into a dull crash, and then the roar of a giant stopped, and a whirlpool appeared on the surface of the surging magma, a crack that the collapsed platform pressed against the drill bit, through which a large amount of magma poured into Drill Tunnel 13.

At first, it was just a very small fissure, but the impact of the magma penetration made the fissure expand rapidly, and finally changed from a fissure to a fissure, the fissure continued to expand, and the rock wall blocked between the two craters was quickly broken, accumulating to the limit, and the volcanic magma that was about to reach the eruption threshold found a vent, and the rushing liquid rock continued to rush towards the mysterious cavity, and soon, the influx of magma had already exceeded the volume of the cavity, but it was still not overflowing, and it seemed to be really a bottomless hole......

When pouring into the lava successfully the cavity is ten times the size of the cavity...... Dozens of times, even a hundred times, it still did not change, but the volcano began to subside, the fissure that was unintentionally drilled by humans began to cool, the magma accumulated in it flowed away, and the remaining small part condensed into folded rock, and the rock that had not yet cooled emitted a dark red light, as if the earth was exposed to the flesh and blood in the air.

The volcanic ash blown out by the scorching strong wind rained down on the ground like droplets, the restless sparks in the air were extinguished one after another, and the ordinary people outside the facility did not know what was happening, but just hugged each other to celebrate the escape...... They immediately opened the door of the blocked facility and organized a search and rescue team to quickly search for the people trapped in it and salvage the equipment that could still be used.

If not trapped at the most dangerous bottom, who would have come up with something like Mark's?

In short, this is a bold challenge to humanity for the future...... It was humanity that narrowly prevailed, no one thought that this crisis had brought them a precious opportunity, if it weren't for Mark and Nina's insistence, maybe this opportunity would have been silently destroyed in the magma along with the facility.
