Shen Yao had Sheng Tang as a miraculous helper in repairing things. She took pictures of Shengtang's dance steps when she was in the southern district of Devil City. She analyzed the movements in the past two days and she really found someone who could do it. The movements and postures match those on the mural.

After the repair plan came out, they held meetings for three consecutive days. The plan was successfully passed. Shen Yao was as happy as if she had won the first prize. She told Sheng Tang, I must treat you to a big meal. Tell me, what do you want most? What to eat?

Sheng Tang is not a foodie, and of course she is not obsessed with eating. She joked, "Why don't you find me a little fresh meat to make me happy."

Shen Yao looked at her in surprise and said, at your age, it is popular to look for uncles, but you are not looking for youth in fresh meat.

Looking for uncle...

Sheng Tang raised an eyebrow: Uncle, are you too bored? The little wolfdog is so fun, lively and cute, he can play with me.

When they said this, they were both in the grotto. Qi Yu was focused on repairing his panoramic painting and didn't bother him. Luo Zhan never participated in such topics and was sullenly adjusting the lighting equipment. Jiang Zhi just came from outside. I came in and listened to the whole story.

He didn't say anything, he just glanced at Sheng Tang.

Xiao was not in the cave, but he called Jiang Zhi, so Jiang Zhi did not comment on Sheng Tang's remarks. The main reason was Xiao Ye's phone call. The cave was absolutely quiet, so Xiao Ye's voice is also quite clear.

"I did a disease bonding experiment on mural modules and found that there is a problem with the glue we are currently using."

It was a matter of work. Jiang Zhi put his cell phone on speakerphone, walked to the area where the gluing was first done, and said, "There is indeed a problem. After the glue was dried before, there was no difference at all."

"Are the tiny cracks reappearing?"

"right."

After hearing this, Sheng Tang hurriedly approached Jiang Zhi and carefully looked at the small area after repair. It was not a big area, just a tiger. The color now looked much more saturated, but the tiger did have cracks on its body. , so small that if you weren’t very close, you wouldn’t be able to see it at all.

Jiang Zhi raised his head and called Qi Yu.

Qi Yu also heard what Xiao Ye said, and was checking the previously treated area. He was surprised, "Some of the nail patches that were attached before have been displaced! How is this possible?"

When restorationists are faced with the task of restoring murals, in addition to the kind of damage that breaks the muscles and bones, such as the destruction of the mountain, or the missing ground, or the statue in Cave No. 0 is missing arms and legs, generally when talking about mural problems, they refer to Problems with the paint layer.

Diseases of murals often occur on the paint layer.

Such as alkali, herpes, chalking and nail polishing, plus hollowing of the ground layer, etc. These problems are often related to the glue added in the paint. The glue in the paint layer is related to the core of the ground layer. Some cohesive materials, such as clay, age, denature and fail under the action of natural salt and water, which in turn leads to the above problems.

During the later restoration, the restorer must choose appropriate glue according to the situation of the mural to deal with these problems, and penetrate the dilute solution or emulsion of the repair material into the paint layer and ground layer of the mural. As the solvent evaporates, the material gradually solidifies. , through electrostatic interaction and partial chemical strength, it interacts with the polar small molecule structure in the pigment layer and ground layer to achieve adhesion and reinforcement.

Qi Yu's repair skills are quite experienced, and he has extensive experience following Professor Hu all the way. Logically speaking, there will be no problems in choosing the type and amount of glue, and what can be guaranteed is that the use of glue can guarantee the longevity, like It has never happened before that something went wrong right after gluing.

That's why he was surprised and said it was impossible!

But the impossible still happened.

Sheng Tang thought of the statue he was responsible for and hurried forward to check it. However, he remembered that the statue had not yet reached the gelatinization step, so he turned back to Jiang Zhi. Jiang Zhi held a lighting tool and carefully looked at the area completed by Qi Yu, with a calm expression.

Sheng Tang didn't dare to show off her anger, and she would follow Jiang Zhi wherever he went.

Shen Yao has been doing research on Xiangxuan Dance from the beginning to now, and the bonding step has not been involved yet, so there are no problems in the area she is responsible for.

Xiao was also stunned on the other end of the phone, "Cracks and displacement at the same time?"

Jiang Zhi had almost finished his observation here. He turned off the light in his hand and said to Xiao Ye, "Yes, the crack is due to the strong adhesiveness of the glue, which leads to differences in mechanical properties between the repair area and the surrounding area; Qi Yu's side failed to achieve the purpose of bonding because the adhesiveness was too weak."

Sheng Tang didn't understand, "But wasn't the ratio already consistent at that time? Especially at Qi Yu's side, if the adhesiveness is too weak, it can be detected on the spot when injecting the glue. If the adhesiveness is not strong, it must be done in the salt." It will lose its viscosity under the continuous action of water and moisture migration, which is at least a long process."

The problem lies here.

Xiao was silent for a while and said, "It seems that I have to re-evaluate the adhesion of the material."

This is an urgent matter. There are two extreme situations now, which shows that the situation in Cave No. 0 is very complicated and rare. In ordinary grottoes, the glue type and dosage ratio can basically be fixed after the adhesion assessment is completed. Already.

But Cave No. 0 is different. On the one hand, the viscosity is too strong, and on the other hand, the cohesiveness is too weak. This shows that in the same cave, under the same external conditions such as temperature and moisture, each The use of glue in murals in one place is also very different.

This makes their job more difficult.

"You can take the test block again."

After hanging up the phone, Qi Yu's spirit collapsed. He squatted there and wailed, "Resetting is too terrible."

Jiang Zhi downplayed it, "You have to do it even if it costs you your life."

Sheng Tang found that Jiang Zhi was really stable, especially when it came to work. Logically speaking, both Xiao Ye and Qi Yu were brought up by Professor Hu. They had never experienced any difficulties and were well-informed, but they still didn't do anything. When it comes to Jiang Zhi's state, his composure remains unchanged despite the collapse of Mount Tai.

Not only does his complexion not change?

Even his eyesight never wavered, it was as normal as facing the question of what to eat tonight.

Seeing this, Shengtang sighed in her heart, he is indeed her most admired fan.

A complete spiritual leader.

**

Cheng Qin actually mailed the human-shaped pillow to Sheng Tang.

air transport.

There is also a sentence attached to the express box: Keep your eyes open and please be kind to those who are destined to you.

The words were left incomprehensible. They were not some slogans put up on a whim by the courier company. They were handwritten by Cheng Qin in a handwriting that Shengtang recognized.

But no matter what, her fantasies finally arrived, and from now on, she could hold him in her arms and fall asleep every night. Not to mention how excited she was when drawing the tape, Sheng Tang's fingers were trembling, the box was opened, and the human-shaped pillow was installed. After entering the compression bag, Cheng Qin pumped out the air completely, and it was still folded in half, flat... fuck it!

How dare you treat her fan like this.

Sheng Tang quickly opened the compression bag, and after letting in the air, the human-shaped pillow expanded rapidly, and she cut the bag directly. When she took the human-shaped pillow out of the bag completely, she was dumbfounded!

this……

I stared at the human-shaped pillow for a long time.

Until I heard someone at the door teasingly say, "Tangtang, I didn't expect you to miss me, senior brother, so much?"

Sheng Tang was agitated and turned to look outside the door.

Xiao Ye came back from the experimental room, followed by Jiang Zhi. He saw that she was holding a human-shaped pillow in her hand. They were both standing at her door, with no one leaving. Sheng Tang looked at Xiao Ye and turned back.

Looking at the pillow in his hand.

It's really one to one, both in height and appearance.

But it wasn't Jiang Zhi, it was Xiao Ye.

I wailed in my heart: Cheng Qin, you are sick, what I want is Fan God! F God!

Then I thought about it, was it mailed by mistake?

Huh? If the mail was wrong, it means that Cheng Qin already has Xiao Ye's pillow. The question is, how could she collect Xiao Ye's human pillow for no reason? Could it be...

Her eyes lit up and she turned to look at Xiao Ye. Just when she was about to tell him that you might be thinking about me, Tie Ci, she accidentally met Jiang Zhi's eyes. Somehow, the words got stuck in her mouth and she couldn't shake them out. She felt

For a moment, Jiang Zhi's eyes were so dark that it made her heart feel tense.

But Jiang Zhi's eyes suddenly changed again.

Calmly and calmly, he then met Sheng Tang's gaze and walked in. He walked forward, took out the human-shaped pillow from her arms, looked at it up and down, half-smiled but said, "It looks very similar."

Sheng Tang didn't dare to answer.

She didn't know why she didn't dare. She vaguely felt as if she had made some mistake. He seemed to be laughing, but it was more like he was angry. She actually wanted to explain that it was Cheng Qin who sent the wrong mail, and what I want is yours.

Pillow...

Xiao Ye leaned against the door, twitching his head and saying with a smile, "Let me see."
Chapter completed!
