"Going back now?" Shanmiya Ha Ren was puzzled, "Doesn't Wei San only have 15 days of vacation?"

After all the back and forth, there was not enough time.

"I will find another excuse to ask the teacher for leave." Wei San said.

"There will be more star storms in the second half of the year." Ying Xingjue looked up at Wei San, "It is predicted that there will be several star storms near the 3212 star this month."

As everyone knows, once a star storm occurs, the port starship will be stationary.

Even the excuse was thought of, Shanmiya Ha Ren had no choice but to agree to leave.

The four returned empty-handed, not only did they not cause any damage to the star beast, but they also damaged Wei San's mecha and weapons.

When they returned to the exit of the stadium, Ying Xingjue notified the people outside to close the exit shield so that they could come out. Instead of taking a break, they headed straight to the laboratory on the planet Sita, hoping to have researchers check the slime of the star beast. However, after they arrived, they found that there was no equipment.

"Our laboratory here is only responsible for studying the bones of star beasts, and there is no such professional equipment." The researcher explained, "If you want to check the inside of the star beast, it is best to go to the planet Imperial City, where the equipment is the most complete, or go to the nearest planet Nanpaxi."

Both Nanpaxi and the planet Imperial City are too far away. It would take them several days to get there from here, not to mention waiting for the experimental results.

After leaving the laboratory, Wei San looked at Yamamiya Ha Ren and asked, "Since the black factory is your gathering place, are there any researchers in the black factory of Xita Star who can do this test experiment?"

As soon as she asked, Yamamiya Ha Ren and Yamamiya Yongnan looked at Ying Xingjue at the same time. Although Gao Tangyin guessed that they were the independent army, he never told anyone else.

"No need to look." Wei San raised his hand and waved in front of the two of them, "He knows."

Yamamiya siblings: "..."

Yamamiya Ha Ren tried to play dumb: "Know what?"

"Know that you are the independent army, and know that the black factory is the gathering place of the independent army." Wei San said directly.

"..."

"Does the Xita black factory have such a laboratory?" Wei San continued to ask.

Yamamiya Ha Ren took a deep breath and tried to calm down: "Yes."

The black factory is the base of the independent army. Because of the existence of infected people, each black factory has set up a laboratory and observation room, but only a few people know about this. And the Yamamiya brothers and sisters, as super 3s-level individual soldiers, are one of the few.

The group turned around and prepared to go to the Xita black factory. Wei San walked beside Ying Xingjue: "Are you feeling better?"

Although Ying Xingjue has been making arrangements in an orderly manner since he left the arena, his face was pale. If he didn't say it, Wei San would not fail to ask.

"It's just that my perception is too exhausted." Ying Xingjue whispered, "Just take a break for a while."

Wei San nodded. Messages kept coming to her laptop, all from Jin Ke and others. When asked what was going on, she could only say in the group that she was fine, but Jin Ke didn't believe it.

Jin's family made a fortune: [Turn on a video.]

Wei San: "..."

Finally, she made a video call, and the other party picked up the call. The four of them stood in front of the camera and looked at Wei San.

"I said it's okay, I'm out of the arena now." Wei San closed the privacy screen and let them look at the surrounding environment. He raised his hand and moved towards Ying Xingjue, "Look, my cousin is fine too."

Ying Chenghe was inexplicably jealous, pushed Jin Ke away, and added a qualifier for Wei San: "It's my cousin."

Wei San: "...Okay."

Ying Xingjue, who was listening to them, suddenly raised his lips and chuckled.

Ying Chenghe in front of the camera was confused by his cousin's laughter. He stood there for a while without saying a word, and was pushed away by Liao Runing: "Wei San, do you need help? I have already thought of an excuse to ask for leave."

Wei San shook his head: "Not for the time being, that star beast is a bit strange, contact you when you need it."

"The shoelaces are loose." Huo Xuanshan said to Liao Runing, standing in front of the camera without leaving a trace and asked, "Do you have enough materials for the Impermanence mecha? I have already sent two sets of 3S-level mecha shell materials, you can use them as spares."

Before Wei San could say anything, Liao Runing, who was leaning over, suddenly stood up: "When did you send it? Why didn't you tell me? Can't you send it together?"

Huo Xuanshan: "I contacted the Imperial Capital Star, and I'm not in the same place as you."

Seeing them crowding in front of the camera and talking nonstop, Wei San smiled, then signaled them to pause: "Mecha materials are needed, and the purple liquid mushrooms can no longer be used. It's too wasteful to deal with this star beast. Let's go to the Xita Black Factory Laboratory to test the mucus and see what's in it, and then think about how to deal with the star beast."

"I've heard about the star beast. You may not succeed once or twice." Jin Ke said seriously, "Contact us if you need anything."

"Got it." Wei San looked at Ying Xingjue on the side, "I'll hang up first."

"Okay."

Before the video was hung up, Ying Chenghe's voice to stop him was faintly heard, but unfortunately, as soon as the signal was cut off, the screen went black.

"You two have a good relationship." Shan Gong Yong Nan in front turned around and said.

Wei San lowered his hands and nodded as a matter of course.

No one in the main team knew that the Shan Gong brothers and sisters came here. Even Yu Pu Xin simply thought that they were just going home to train. But even if they knew, they would only be scolded by Gao Tang Yin. The last time they returned to school, they made a scene. Thinking

of this, Shan Gong Yong Nan couldn't help but sigh in his heart. Anyone who knew that they had been kept in the dark for so long would probably be unhappy.

The four did not stay on the first floor of the West Tower Black Factory, and went directly to the fifth floor.

"I remember that you also have level privileges in the Black Factory." Yamamiya Ha Ren asked Wei San after he finished brushing in the elevator.

"You can only go to the fourth floor underground." Wei San said, "What is there on the fifth floor underground?"

"There is only one arena on the fifth floor underground, and the rest... you will know after you see it."

When the elevator came, the four walked out. This place is completely different from the first floor above, with all white passages and one laboratory after another.

"There are not many people here. Only high-tech researchers can stay here. They usually don't take the initiative to go out. Only when the black factories communicate with each other will they be open to enter and exit." Yamamiya Ha Ren explained along the way, and soon someone came to find them and asked them to show their identities.

After showing their authority, the Yamamiya siblings asked where the laboratory for studying star beasts was

. "Turn left and it's the sixth room." The person in charge of the fifth underground floor said that these two people had extremely high authority and as the person in charge, they needed to tell them everything they knew.

The Yamiya siblings led the two to turn left. Ying Xingjue scanned the surrounding laboratories and asked, "Is this a laboratory for studying infected people?"

The Yamiya siblings paused in unison, and then Yamiya Ha Ren said, "Partially, some infected people who are found will be locked up here for research. A lot of information about the infected people in our independent army comes from the laboratory on the fifth floor underground of the black factory."

Walking to the sixth laboratory, Yamiya Ha Ren found a researcher to explain his purpose.

"There is also this kind of mucus?" The researcher said as soon as he heard it, "It doesn't make sense. Can I take a look first?"

Wei San took out the box containing the mucus. As expected, the inside was corroded again.

"Even the collection box can be corroded?" The researcher was immediately interested.

Wei San explained the properties of the mucus in detail and asked, "How long will it take to get the results?"

"If we test it according to your guess, we will get the results tomorrow afternoon." The research institute found various anti-corrosion materials, and all of them showed corrosion.

"Is there a resting place on the fifth floor?" Wei San turned his head and asked Shan Gong Bo Ren.

"Yes."

"In that case, let's stay here and wait."

After discussion, all four of them stayed on the fifth floor underground of the West Tower Black Factory.

...

The resting room was not luxurious, but it had everything it should have. After Wei San washed up, he lay on the bed for a long time without falling asleep. Finally, he turned over and went to find Ying Xingjue to see how he was doing.

After Wei San knocked on the door, he looked at his slightly red lips and suddenly didn't know what to ask.

"Come in." Ying Xingjue opened the door and took a step back.

Wei San walked in and turned to look at him: "Can you hold on to controlling that star beast again?"

Jin Ke said that they might need to contact the star beast several times, she didn't care, as long as the materials were enough, but at the same time, Ying Xingjue would need to control the star beast several times, which might exhaust his perception.

Ying Xingjue looked up at Wei San: "Although the mental power of super 3s star beasts is strong, it is not insurmountable."

It was indeed tricky for him to contact a star beast that could resist his perception for the first time, but he could do better next time.

Wei San stood opposite Ying Xingjue and said after a long time: "Don't force it."

The two stood in the room. Obviously, the place was not small, but for some reason they felt that the space inside was a bit cramped.

"I'll go back first, good night." Wei San said hello and left in a hurry. Ying

Xingjue didn't even have time to say good night in return.

He stood there for a long while, and finally turned around to close the door, leaned against it, and whispered, "Good night."

...

At noon, the researchers got the test results and excitedly called them over.

"You guessed it right, this slime is artificially synthesized." The researcher's tone was full of surprise, "I don't know how it was done, anyway, this synthetic slime can corrode most of the anti-corrosion materials on the market."

Wei San didn't want to hear this, she asked: "Is there any way to prevent this slime from corroding the mecha?"

"You asked the right person!" The researcher said excitedly, "Since you said it yesterday, I have been thinking, if this slime is really as you said, what method should be used to solve it."

"So is there a solution?" Yamamiya Ha Ren asked.

The researcher nodded: "Yes, since it is artificially synthesized, it is full of familiar corrosive slime, so it is not difficult to solve. I can also synthesize a coating material to prevent corrosion against this slime."

"How long will it take?" Wei San asked.

"This..." The researcher calculated, "Although this artificial slime is powerful, the separated components inside have materials that can solve it. It just takes some time to synthesize the coating material. I have to find a suitable adhesive. Probably... two days, it can be done in two days."

Two days...

Wei San thought for a while and said: "Okay, please make a coating to prevent artificial slime corrosion in two days."

"Leave it to me." The researcher said excitedly.

...

Several people don't know much about this kind of professional matter, so they can only wait here. During this time, Wei San took Ying Xingjue to the upper floors for a walk.

Two days later, the researcher called them over with dark circles under his eyes, saying that he had found a suitable adhesive, and as long as it was mixed into various anti-corrosion materials, a suitable coating for the mecha could be made.

Wei San took over the work behind the scenes, borrowed the fifth-floor laboratory, added coatings to their mechas, and repaired the impermanence at the same time.

One day later, the four entered the West Tower Arena again to look for the star beast.
