Thinking of Tang Yan's engagement ceremony that Tang Wanjun said, although Zhou Zheng planned to go there, he just wanted to study the piece of jade and solve his doubts, and there was no turmoil in his heart.

He has seen too many beauties, whether intentionally or not, and has saved a lot, but he will not be easily tempted. Not to mention a person who already has a marriage contract with someone else.

It's just that Tang Yan's attitude towards himself on the train made Zhou Zheng feel a little favorable, so he said those words to Tang Wanjun. They decide their own affairs, and Zhou Zheng can't say anything.

Even if it is not a mutual relationship, even if it is not an agreement recognized by law, it is inappropriate for outsiders to interfere at will.

For example, if Zhou Zheng knew that someone was pursuing Liang Yulan, he would definitely feel unhappy, and even have the heart to find that person to beat him up. This is the instinct of male animals.

Even though he and Liang Yulan have already said that they are willing to start getting along with friends from a normal and suitable starting point, they have not explicitly said that the marriage contract will be annulled.

Walking on the boulevard of Haicheng Academy, Zhou Zheng continued to quietly absorb the aura of the surrounding heaven and earth, strengthening his own transformation realm that was not yet completely stable.

Unconsciously walked to the same tung tree that he had hugged Wu Chuge for the first time, Zhou Zheng stopped and began to sit on the grass, entering a state of false sleep, and meditating on cultivation.

"Little evil god, don't you want to show up soon?"

While practicing, I suddenly heard a familiar lively girl's voice.

Zhou Zheng opened his eyes, and through the scattered sunlight spilling down the leaves, he saw a girl wearing a waist-tied white shirt and blue slim-fitting jeans.

The girl was holding her mobile phone and took a picture of Zhou Zheng, "Click!"

As the phone slowly moved down, Zhou Zheng saw Liang Yulan's bright and moving face, as if he was a little thinner than the last time they met, and happened to look at himself with a smile.

"Little evil god ......" Zhou Zheng was in a bit of a trance at this moment.

Although he knew that Liang Yulan was just a title for unintentional jokes, to him, this nickname was really used on the Tianxuan Continent.

In the hundred years before meeting Meng Li, when he was under the name of the first master, many people called him so.

Zhou Zheng stood up and came to Liang Yulan's side. "When did you come to Haicheng? and don't give me a call. ”

Liang Yulan pouted at Zhou Zheng's pocket and didn't explain.

Zhou Zheng took out his mobile phone and saw that there were three missed calls from Liang Yulan. I didn't expect it to be my own problem, so I turned it to mute in order to meditate and cultivate.

"Have you eaten it? Zhou Zheng said.

Liang Yulan is more than 1.7 meters tall, almost the same as herself, Zhou Zheng has seen a lot of female classmates and Wu Chuge around her, and now she is at eye level with Liang Yulan, and she is not used to it at all.

Liang Yulan took out her mobile phone and looked at the time. "Wait a minute! I came to Haicheng College, in addition to wanting to meet you, I also want to find an old professor from the School of Chemical Engineering by the way. ”

Zhou Zheng smiled, "It should have come to visit the old professor and met me on the way, right?"

"Whatever I say, whatever you think. Liang Yulan smiled and shook her head slightly, "Come with me!"

The two walked towards the chemical light industry laboratory building of Haicheng University. Liang Yulan is familiar with the road and is obviously a frequent visitor here.

It is not difficult for Zhou Zheng to understand this, her mother Ye Haiyun is also a big man in the light chemical industry, and she is one of the well-known alumni of Haicheng College, graduated from the School of Chemical Engineering. A large portrait is printed on an alumni billboard on campus.

Coming to the laboratory building, Zhou Zheng, under the leadership of Liang Yulan, entered the largest laboratory on the third floor.

At this time, there were seven students in white lab coats in the laboratory, and there were also some colorful unknown reagents reacting in various instruments on the table, a faint roar in the oven, and the air was filled with the fragrance of cosmetics.

Seeing Zhou Zheng and Liang Yulan walk in, a handsome boy with a height of about 1.8 meters and deep double eyelids put down the work in his hand and took off his mask.

With a light in his eyes, he glanced at Liang Yulan without a trace, revealing a bright smile.

"Hello, who are you looking for?"

When the other students who were doing experiments heard this, they couldn't help but stop what they were doing and looked at Liang Yulan a few more times, their eyes full of envy.

"Don't you plan to eat?" said the tall boy dissatisfiedly, and the men quickly looked away.

Hearing that this person just said hello, not you, Zhou Zheng didn't plan to step forward.

Besides, he didn't understand these things, so he moved a chair and sat by the door.

"I made an appointment with Professor Shen and waited for him in this laboratory. Liang Yulan said with a light smile.

"Oh, please take a seat. Drink water? I'll pour you a glass. ”

With that, the boy went to the water dispenser and connected the water with a disposable paper cup. And really only took one cup and sent it to Liang Yulan.

Zhou Zheng didn't care about this, but he didn't expect that he and Liang Yulan would walk together, but they would become air.

Liang Yulan looked at Zhou Zheng, who was sitting calmly in the chair, and did not drink water, but walked towards the instruments that were reacting.

"My name is Zhang Chuanshi, I am a student of Professor Shen, and I was just recruited by the professor this year from the main campus of Handong University, a master's student, mainly in the direction of light industry cosmetics. Do you know what to do?"

"A little bit of it. ”

Liang Yulan paced slowly among the various instruments and reagents, observing the operating data of certain instruments from time to time, or gently fanning the air a few times with her hand to smell the smell.

Zhang Chuanshi followed Liang Yulan's side very gentlemanly, and explained the relevant professional knowledge to Liang Yulan.

"This part is the raw material phase A, the main components are deionized water and carbo, trace amounts of polyacrylate ......"

"It's 100 percent octadec alcohol, stay away from it, don't splash it on your body. There are also phase cyclic methyl silicone oil and diisopropyl adipic acid, which are essential ingredients in the preparation of anti-moisture smoothing creams. Your skin is so good, what kind of cosmetics do you usually use?"

Liang Yulan didn't answer, but pointed to the milky white liquid that was being stirred in a large container.

"The vortex is a bit small and the agitation is not sufficient. The motor frequency can be increased appropriately. Otherwise, it will affect the lubricity of the final product. ”

"The reaction temperature here is 73.5°C, which is a bit too conservative. Since it's an experiment, you should let it go, and don't dare to try it because you're afraid of failure. ”

Liang Yulan said, directly raising the temperature to 76.5 °C.

This move shocked Zhang Chuanshi, and he quickly reached out to call back. "Beauty, this thing can't be moved casually! This is a fine chemical, even a temperature difference of 0.5 will greatly change the nature. How dare you turn it up to 3°C directly!"

Zhang Chuanshi said with palpitations.

They have been doing this experiment for two days, and they can get the results today, of course, they don't dare to let Liang Yulan debug it casually.

"The reaction temperature of the aqueous phase A component, the internationally recognized maximum temperature cannot exceed 75 °C, which is basic common sense. Don't you even read papers?"

Liang Yulan smiled, "But as far as I know, MIT just released a paper last month that confirmed that exceeding this temperature can have a better reaction effect." It is just that 2% aminomethyl propanol and acetyl lanolin need to be added. ”

Listening to what Liang Yulan said, Zhang Chuanshi's face was also full of shock. Even the students who were doing the experiments looked at her in disbelief.

Zhang Chuanshi's face was a little unnatural, and he seemed to be unwilling to lose face in front of such a beautiful woman, "I have been paying close attention to foreign related paper websites, and I have never seen the paper you said, why is this?"

"That's because you don't have enough access to your account. ”

At this moment, an old man with gray hair but strong spirits and black-rimmed glasses walked in with a smile.
