Du He and Dong Haofan alternated with Professor Lan Zhu, and each took this opportunity to learn the real swordsmanship, so the cooperation was much more harmonious at this time, and there would be no more situations that almost hurt each other.

But their cooperation was too smooth, Lan Zhu's side couldn't bear it, he couldn't understand how two ordinary human teenagers could become so powerful in a short period of time?! When he focused on defense and kept retreating, he reversely recalled the critical point of the opponent's change from weak to strong, what was the reason why they suddenly turned from a layman to a peerless master?

He suddenly remembered a detail just now, that is, they had fought with him alternately, and used the free time to touch those columns, what did this action represent? Are these columns giving them some hints?

Before fighting Du He and Dong Haofan, Lan Zhu didn't know what the area he was hiding was for, he only knew that this area was completely isolated from the rest of the building, and it was not monitored by the central console. Because he was so focused on hiding, he didn't pay close attention to the pillars beside him.

At this moment, he gave up blindly fighting Dong Haofan and Du He in front of him, but flew towards the far end, and took the opportunity to look at a pillar next to him.

Sure enough, let him find out. The thin seal carved on that pillar was nothing else, but a copy of the various data in the MM system that he had painstakingly stolen. It's no wonder that the two teenagers became so powerful just by touching the pillar, it turned out that they had learned the swordsmanship recorded in the pillar.

He didn't know how many sets of swordsmanship the two of them had learned, but their level at the moment was already quite difficult to deal with, and if they were given another chance to learn, he would probably really die here. It may not be accurate to say that he is dead, because he has already died, but in order to be able to complete the great cause with his mother, even if he survives, he must survive, even if it is only in this virtual world forever.

The only way to stop these two human teenagers from becoming stronger and hungry is to destroy all the pillars. But it was now difficult for him to even temporarily dodge their onslaught, let alone destroy hundreds of columns.

In desperation, he had no choice but to give up the precious information he had already obtained. Although it was a pity that he had infiltrated the MM system several times, and the information obtained after a long period of hiding and investigation had been abandoned like this, he had to abandon it in order to continue to exist.

He took out a long and thin metal cylinder from his arms, shook it in front of Dong Haofan and Du He's eyes, and said, "This is all the information I have obtained, they are all in it, and now I will hand it over to you!" Then! ”

With that, he threw the metal canister out.

Dong Haofan and Du He were anxious to see whether the so-called metal copper containing the information was real or fake, and ignored the blue bamboo opposite for a while.

A wicked smile appeared at the corner of Lan Zhu's mouth, and he quickly took out another oval object from his arms, and while throwing the object to the ground, he rushed to the entrance of the stairs leading to the outside.

"Bang!"

With a loud bang, the entire mezzanine shook for a few seconds, and in the thick smoke, the destroyed columns collapsed one after another, and the figures of Du He and Dong Haofan disappeared.

In the blink of an eye, Du He and Dong Haofan had left the central control room for a while. Liu Lingmei also went from fidgeting to completely unable to hold back her emotions, because what was happening in the mezzanine was something that she and Min Entong couldn't grasp at all, so she couldn't stop thinking about whether Du He and Dong Haofan were in danger.

"No, I have to find out!" As she spoke, she was about to rush out of the central control room.

"Wait a minute!" As soon as Min Entong raised his hand, he used the program similar to 3D animation software to copy two laser swords, and then handed one to Liu Lingmei and said, "Just in case!" ”

"Hmm!" Liu Lingmei nodded, took the laser sword, and pinned it to her waist.

The two took the elevator to the 73rd floor, and after successfully finding the entrance to the staircase leading to the mezzanine, Min Euntong quickly analyzed that the password through the small door was in Japanese, "I'm back!" ”

As soon as the door opened, a strong smell of nitroglycerin came out, followed by smoke that made them both unable to open their eyes.

"Not good!" Min Eun-tong shouted and stumbled up the stairs that had been badly damaged.

Liu Lingmei followed him, crying as she ran, she had a strong sense of foreboding, this feeling made her tremble all around, as if there was a cold air pouring into her whole body from the top of her head, making her fight uncontrollably.

The mezzanine was in shambles, and the columns were so badly damaged that the ceiling collapsed in large chunks.

Min Entong kept crawling over the obstacles on the ground and shouted loudly: "Du He, Dong Haofan!" Hear me? When you hear it, give it a hint! ”

After waiting for a while, a faint cry for help finally came from not far away.

"Eun Tong! Lingmei! We're here! ”

It was Du He's voice, and Liu Lingmei, who was already crying into tears, stopped her tears in an instant. She hurriedly followed Du He's voice with Min Entong, which came from the wreckage of a pile of pillars stacked together, and they should be right underneath.

"Are you hurt?"

Min Entong carefully checked which column wreckage was superimposed, and tried to turn on the laser sword to carefully cut some of the large pieces of wreckage on it into small pieces, this process proceeded extremely slowly, because the slightest deviation could hurt Du He and Dong Haofan underneath.

"I'm okay, I'm afraid Du He has broken a few ribs, and now it's a little difficult to speak." Du He replied, his voice sounding quite powerful.

"Woooooooooo......oo Scared the hell out of me! Liu Lingmei couldn't help crying when she heard his answer.

"Who is crying like calling the police?" Du He teased Liu Lingmei in this way to ease her emotions.

"It's all this time, and you still have the heart to joke?! People are worried about it! Liu Lingmei pretended to be angry and said.

"Okay, okay, I'll wait for me to go out and let you deal with it later!" Du He comforted her flatteringly.

"That's what you said, see how I clean you up!" Liu Lingmei burst into tears and laughed.

"Don't just talk about love, come and help!" Min Entong said directly without mercy.

"Oooh!"

Liu Lingmei wiped the tears from her face and began to help Min Entong move the remains of the column cut into small pieces to the side. Slowly, from the gaps in the remaining wreckage, Du He and Dong Haofan could already be seen.

"Almost, I can't use the laser sword anymore now, because it's likely to hurt you and Dong Haofan by mistake! Liu Lingmei and I are moving outside, and you push hard inside to see if you can get this piece of wreckage open. If it doesn't work, I'll call someone again! Min Entong said to Du He, who was looking at him and Liu Lingmei through the cracks.

"Good!" Du He replied crisply.

"You give orders!" Min Entong said to Du He.

"Hmmm! Come on!" Du He took a deep breath and shouted, "Begin!" ”

So the three of them worked together to move the wreckage with all their might. Just as everyone's strength was about to be exhausted, the wreckage finally made a "click" sound, and then was pushed aside.

Du He, who was sitting on the ground, smiled and beckoned to Min Entong and Liu Lingmei, and handed the metal cylinder in the other hand to the two of them, and said, "I read it, it is indeed the information of the MM system." It looked a bit embarrassing, but we were able to complete the mission! ”

"Dong Haofan, are you okay?" Liu Lingmei leaned over and patted Dong Haofan's face, who was half-squinting.

"Oh, you can do it lightly, okay?! I wasn't stoned to death, but you shot me to death! Dong Haofan grinned and said, although his voice was a little weak, but since he had the strength to joke, it meant that there was no danger to his life.

"Okay, you've really done a great job this time!" Du He said very sincerely, with a hint in his eyes, "At the last moment, his reaction turned out to be to protect me, or he wouldn't be injured, I'm convinced!" I'll thank you again when I go back! ”

"Ahem, good friend of good base, what is there to thank you for!" Dong Haofan insisted on squeezing out a smile.

"Find a way to get him out first!" Min Entong thought for a while and said to Liu Lingmei, "You go outside and call a few people, the technicians here should also have mastered the medical treatment in the MM system, and it is likely to develop to another realm and level." ”

"Good!" After Liu Lingmei finished speaking, she turned around and left.

Soon, several people carried two stretchers in, and they and their professional and skillful movements moved Dong Haofan and Du He to the stretcher, and then carried them in front to lead the way.

Min Euntong and Liu Lingmei followed the men to the elevator to the 99th floor. This level is dedicated to medical care, and there are many new and unusual instruments that they have never seen or heard of.

Dong Haofan and Du He were each placed in two instruments similar to oxygen chambers, which first scanned their whole bodies, and the results of the scans were varied, including various indicators of the body, the length of the injury, and the level of fatigue...... And so on.

Du He suffered minor injuries, so the device only treated him with a few simple steps, and he was fully recovered.

Dong Haofan's injuries are more serious, but it is not difficult to overcome this miraculous instrument, which also has the function of surgery, repairing his damaged bones, muscles and even skin tissue without any pain. When he came out of the machine, he was completely new.

After moving his arms and legs a few times, he couldn't help but exclaim, "Hey, I feel like I'm healthier than before!" ”

"It's almost time for us to go back! It is estimated that Teacher Dong Muya must be in a hurry! Liu Lingmei checked Du He and Dong Haofan back and forth, and said after making sure that they had recovered.

"yes!" Min Euntong also felt that it was time to go back.

"But how are we going back?" Dong Haofan couldn't think of a way to go back for a while.

"It's not easy! Go to the central control room! Min Entong was confident, he knew that this place existed in the MM system after all, so there must be a way to get in touch with Dong Muya.

Together, they returned to the central control room and entered a series of passwords in the main console, actually trying to get in touch with Dong Muya.

Before they could figure out what was going on, they had already returned to the underground database, and the four of them sat up from the bathtub filled with hot water back and forth, looking at everything around them in a daze, and for a while they were still a little unsure whether they had really returned to the real world.
