Mark had forgotten how he had done this series of work, he only remembered that he was in pain all over, his mind was swollen, he stood up with his will alone, his mind constantly replaying what Nina had taught him, and his body walked to the front of the console very mechanically, and completed the operation process clumsily but correctly.

The hexagonal bezel on the visor flickered, and it was clear that closing the door had no effect on the temperature, only reducing the risk of an explosion. After opening the thirteenth pit, Mark didn't dare to rest for a moment, and quickly moved to the next work platform with his puppet-like body, he didn't have a communication device in his hand, he couldn't determine what was happening below Nina, and he couldn't get in touch with Nina if he encountered any problems.

So all his operations had to be successful at the first time, and Mark kept replaying the process of Nina telling him in his head, again and again...... When his hand touched the lever, Mark even felt like a veteran who had already controlled the machine countless times.

It was this strong will that drove him to completely switch the drill bits in half the time planned, and now all three nanomaterial bits are aimed at the drill well where the lava seeps out.

Through the red-hot drilling on the work platform, Mark saw directly the lava surging below, which had overflowed the ruptured drill tunnel, and the high-pressure gas gushing out of the ground kept pushing them high, and from here, he could see patches of churning fire, and the lava surging as it propelled and rolled out layers of folds, solidifying into brown semi-solid at the very edge, like a burning wave on the sea, slapping towards the shore in waves.

The waves are erosive, and the coasts and reefs have been eroded by the waves for thousands of years and have been constantly retreating to land, but what about the fire waves in front of you? Mark saw that in an instant, the large machinery placed below was swallowed up by the gushing lava, which was a transportation device made of high-strength steel up to fifty meters high, and it quickly began to deform under the high temperature, and began to melt rapidly from below, and the flowing magma formed folds under the resistance of the steel, and soon swallowed all the large machinery below.

Mark swallowed, the world around him was still distorted in the heat, but his vision was much clearer, and his mind was clearer than ever, he counted three times in his mind, and then pulled down the lever and controlled the three nanomaterial drill bits to rush down.

The black and silver nanomaterial drill bits were spinning rapidly, Mark dissolved the automatic operating system, and used manual control to make their rotation speed reach the limit, the whirling drill bit made a buzzing roar in the scorching air flow, as if it was competing with the loud noise coming from the fault below, and soon the drill bits reached the limit speed, and the boom supporting them and the working platform above were vibrating, and Mark could feel the earth-shattering roar of the turning machine through the ground under his feet.

"Start!" Mark gritted his teeth and shouted in his heart, adjusting the angle to the best position, and pushing the lever in his hand to the bottom.

The three drill bits quickly rushed downward, and the farther they went, the more viscous the hot wind became, and the sparks scattered in the air hit the rapidly rotating drill bits, and then were tossed high along the rotating drill teeth, and the sparks became denser and denser, and before they even touched the lava, the drill bits were already splashing everywhere, as if they were drilling through an invisible steel wall.

But even if there are real steel walls! Mark has to break through it!

No wall in the world can be more frightening and terrifying than the endless wall of darkness. Compared to the fear of being closed by the dark curtain, and the helplessness of waiting for the dusk to fall, these difficulties in front of him seem to be worth mentioning, Mark does not feel pain and fear at this time, all his attention hits the screen in front of him, the drill has been lowered to a position of nearly 100 meters below, and he can no longer see it with the naked eye, he can only adjust the position of the drill bit through the data transmitted from the screen.

Originally, the drill arm was equipped with a camera, but at such temperatures, the camera was no longer usable, and the picture on the monitoring screen was blurry. But even if there was only rough data, it still didn't affect Mark's judgment of where it was, and he was engrossed in staring at the numbers on the screen, two hundred meters...... 300 meters...... Rumble!

With a jolt, the drill bits began to slow down, and the speed was greatly hindered, and it was clear that they had been plunged into the magma, and it was a matter of success or failure! Mark moved a chair behind him, adjusted the angle, and slammed it onto the countertop, just enough to jam the lever.

The drill bit below pierced into the hot red lava, splashing out fiery red waves, the drill bit that was originally roaring and charging like a beast out of the cage is now unable to move an inch, and the dense and viscous magma is like countless hands, holding the drill bit from all sides, although the drill bit keeps breaking free, but those "hands" will soon adhere to it again. Three flowers exploded on the surface of the lava sea, and the drill bit kept stirring the liquid surface, although it was difficult, but it stabbed steadily into the bottom layer of the lava.

"Boom! Bang! "There was another series of explosions, compared to the huge vibration from the ground, it was like a light raindrop, but the destructive power of this sound was extraordinary, the entire working platform at the top began to tilt, located on the side of the platform, the bracket connected to the mountain wall was scorched black, and a large fire was still emitting, apparently there had just exploded.

The explosion lasted for several minutes, until all the water vapor accumulated in the fire system leaked out and exploded, and then the firecracker-like sound gradually stopped, compared to the volcano below, maybe it was a firecracker, but for Mark it was not like this, after the detonation he had nowhere to hide, so he had to hide in the gap in the rock wall, which should be left by volcanic activity, to be honest, it was very dangerous here, once the geological movement changed again, this crack could close at any time and squeeze him into a pulp.

But without Mark, there is nowhere else to hide, and he is more worried about Nina than himself, the cable car has been used by himself, how will she escape? When she left, Nina told him that she had a solution, but she didn't say what it was......

The platform slowly sank like a shipwreck that hit a rock, the huge structure really fell apart, the main support began to deform and twist in the face of the huge pressure, Mark had already done all his work, now just waiting for it to crash down, and drive the drill into the ground to break the fault! What Mark didn't expect, however, was ...... The platform was structurally stronger than he had expected, and without a row of brackets to support it, it had withstood a series of explosive impacts, but it was still hanging there, and it had not fallen as they had expected.
