I have to say that a person's mind always changes slowly over time. At first, he just wanted to cook some rice and then cook the rice. But when he opened the refrigerator and saw the ingredients piled up inside, Bai Xiao thought, would he really have to wait for Lin Shan to come back before he was busy cooking?

Is it too ungrateful to be a rice worm that is "just open to the mouth" like this? His lively conscience felt strongly condemned. Thinking of Lin Shan's daily efforts, Bai Xiao suddenly felt that he seemed to be doing something, at least to make himself feel a little more at ease.

So, when Lin Shan came back, Bai Xiao was busy preparing two side dishes.

Smelling the fragrance of the dishes from the kitchen, Lin Shan was surprised, and a smile appeared on her face, raised her eyebrows, and she jokingly said with a three-point sound: "Oh, the Bai family still has an unmarried daughter, she is pretty and versatile, and she is cooking and tender, and I don't know who is looking for good news."

Bai Xiao saw Lin Shan making jokes as soon as she came back. She raised her eyebrows and was about to refute her a few words when a chuckled suddenly flashed across her face, shook her head, and her eyes fell on Lin Shan's hand.

"What's this?"

"The roast duck at the south gate..."

Lin Shan held the paper bag in her hand and said with a smile: "I thought I would have to cook when I came back, so I bought a roast duck. Who knew that the cook at home had already cooked the food almost. When I thought about this, I felt emotion and relief."

"I'm so please, I'll leave the rest to you." Bai Xiao laughed and cursed, and as he said, the figure flashed, walked out of the kitchen directly, wrapped his hands, took off his apron, and put it on Lin Shan's body.

Lin Shan was stunned for a moment, then her face changed, and she looked at Bai Xiao helplessly: "You are really so lazy. You have to start and end things well, and the dishes are only half done. How can you put a load on it? A dish that needs to be completed by one person is perfect, otherwise you will lose your true nature."

Bai Xiao would not listen to her fooling around. Seeing this, she did not hesitate at all. She put her hands directly on Lin Shan's shoulder and turned her around, then pushed her into the kitchen.

Lin Shan's mouth twitched slightly, and her voice sank, "Xiaoxiao, it's wrong for you to give up halfway."

However, Bai Xiao was very casual. She clapped her hands and walked towards the living room, making up her mind not to interfere in the kitchen anymore. Lin Shan shook her head when she saw this, feeling that Bai Xiao had not learned her cooking skills yet, and she began to swell. She could not devote herself to the training of cooking skills meticulously, and she would probably be a half-baked cook in the future.

It was a pity that she sighed, but then she thought of Bai Xiao's identity and felt that it was boring to be entangled in trivial matters.

Bai Xiaoxiao, that's the existence of "to inherit billions of property". Being a cook, she is wronged. People are so different. The lives of rich people are often so simple and unpretentious... no, it's enviable.

Not long after time passed, Lin Shan cooked the remaining dishes and brought them out and called Bai Xiao to come over for dinner.

Bai Xiaoshi walked over, and a greedy female ghost followed behind her. After sitting down, she showed her eyes and picked up the chopsticks and started eating in small mouthfuls.

After the meal, she cleaned the dishes and finished her daily body cleaning as usual. It was getting late. Bai Xiao said good night to Lin Shan, then went back to her room, sat on the bed and started practicing with her eyes closed. Lin Shan was already tired for a day. She was about to watch a wave of online dramas without any movement, and she was also preparing to take a break today.

The staff is complete, and it is time to go to work.

"Zoom Up Platform" laboratory.

Bai Xiao put on his experimental clothes and followed Zhao Tingran to the ultra-clean workbench in the clean room.

What they are now going to do is the "gene conversion" of microorganisms. The so-called transformation means transferring external genes into the body of microorganisms and integrating them into a complete engineering cell.

"The transformation of microorganisms requires the use of plasmids with the ‘destiny gene’ constructed in a single chamber, and also needs to be host cells of the recipient. This type of host cell, we call it 'competent cells'."

While explaining to Bai Xiao what "competent cells" are, Zhao Tingran took out two keys from different places and then took Bai Xiao to a large ultra-low temperature refrigerator.

"This is a -80c refrigerator, where pre-prepared competent cells are frozen."

Zhao Tingran smiled at Bai Xiao, and opened the thick door lock of the refrigerator with the key. Then, with a burst of white smoke falling down like a waterfall, a stream of air conditioning came towards her. She put on insulation gloves and quickly took out a small tube about the size of a little finger from a small groove.

Quickly put the "tube" into the crushed ice that Bai Xiao had prepared in advance, then closed the refrigerator, and the two returned to the ultra-clean workbench again.

"Then you will do it. Use a pipette to absorb about ten microliters of the 'target gene' and inject it directly into the competent cells. Then put it on ice and let it sit for 30 minutes, wait for the gene to adsorption, and then heat strike in a 42c environment, and then you can introduce the gene into the cells."

The work flow is actually not complicated. Zhao Tingran briefly explained it, and then explained the principle of why each step was operated like this. Although these processes have been learned in school, after Zhao Tingran said this, Bai Xiao suddenly realized that the blurred parts of the past were clear.

He followed Zhao Tingran's instructions at once. Bai Xiao's operation method was obvious, after professional training, which made Zhao Xinran nod frequently after watching it, and then she showed a faint smile.

In fact, Bai Xiao realized afterwards that he felt that he was always shallow when he was studying. The method he handed in school was indeed a standard method, but it seemed a bit deliberate and artificial in actual operation.

Real old fry, or veteran drivers, are often "based on routines and beyond routines". Only after doing more experiments will you know that the precautions mentioned in textbooks are mostly nonsense, and are highlighted in order to develop good working habits of the experimenters. In real experimental operations, the techniques are actually quite casual and do not need to be so rigid.

Of course, problems with the experiment are mostly caused by these "scheming".

The morning time passed quickly, and after lunch break, Bai Xiao got up and read quietly.

In the following days, Bai Xiao participated in the experiment step by step, with the joy of success of the experiment and the frustration of the cells being contaminated and abandoned. At the same time, her experimental record book and the practice record sheet issued by the school were gradually enriched.
