Twilight had come, but when Gu Li knocked on the door of the neighbor's house, Wu Bai did not show any doubts.

He said, "Miss Gu is here." ”

As if I had expected her to come.

Gu Li smiled and said; "Brother Wu just sent the dishes, and I like them very much, so I want to meet the cook, I don't know if it's okay."

She knew that she was bored, just as boring as the hen that had laid the eggs after eating them. But she couldn't let it go, she couldn't wait to know, who was the person who made these dishes?

If the taste similarity of a dish is a coincidence, then the taste of each dish is similar, which is not explained by coincidence.

"Naturally, it's okay, Miss Gu, please come in." Wu Bai turned sideways, let go of the door, and invited her in.

Gu Li followed behind him, bypassed the bamboo bushes at the door, and walked into the courtyard.

The courtyard was quiet, and there was no light in the main room, but in the room next to the plane tree, there was a hazy light shining through the green screen window.

Gu Li still remembered this room, she fell asleep here that day, and it was in this room that she woke up the next morning.

Could it be that there is someone living in this room? Who lives there?

Before Gu Li could come up with a reason, Wu Bai said to her, "Miss Gu, it's here." ”

Gu Li came back to her senses and happened to see a person walking out of the kitchen, a young man.

"This is Miss Gu, she is very satisfied with the dishes you made today, so she wants to meet you." Wu Bai said to this man.

Instead, he introduced Gu Li again: "Miss Gu, this is the new cook, Song Heng." ”

Gu Li smiled at him and greeted him politely: "Hello." ”

Song Heng seemed to be busy, with a white apron tied around his waist, and he also smiled at Gu Li and said hello.

"Did you really make those dishes?" Gu Li asked.

Song Heng is not good-looking, with a little honest look on his face, Gu Li really can't imagine that such a wonderful delicacy is actually from his hands.

"Yes", Song Heng replied, "How does Miss Gu feel?" If you have any comments, please let me know. ”

His words were modest and confident, which made Gu Li laugh and replied: "I've done a good job, I really can't think of anything bad." ”

In fact, the purpose of her coming here was not to talk about the dishes, but mainly to take a look, was the new chef the person she thought he was?

Now I've seen it, and I know it, no.

In this way, Gu Li put her mind at ease, said a few more greetings, and left.

Just as she was about to walk out of the small courtyard, she suddenly looked up and saw a figure holding a scroll on the green screen.

Gu Li was puzzled, could it be Fang Gongzi?

But looking at the silhouette, she didn't feel like it.

Gu Li didn't think too much, if that person wasn't Fang Gongzi, maybe he was a guest at home, she had heard that guest playing the piano a few days ago.

Gu Li walked out of the door, the silhouette on the green screen window moved, and the scroll in his hand was put down.

Gone? Yan Qing's eyes were soft, and his lips smiled lightly.

He had expected that she would be able to taste him, and he would definitely come to see what was going on.

She has been getting along with Mei Zhiyan day and night recently, and she has the intention of agreeing to marry Mei Zhiyan. This is a complete forgetting of him.

In that case, he reminded her.

Gu Li didn't know that Yan Qing actually brushed a sense of existence in her heart in this way.

When she returned home, Jin Zhi had finished eating.

"Sister, why did you run out without eating? I'll keep it for you, hurry up and eat it. The golden branch said to her.

Gu Li agreed, sat back at the table, and continued to eat.

Now that she knows that these dishes are not made by Yan Qing, but by the hand of the cook named Song Heng, she feels much more down-to-earth when she eats them at this time.

After eating, Gu Li washed the empty plate and planned to return it tomorrow.

The next day, Gu Li planned to carry out the next experiment, so she went to the Spring Return Hall early.

When she arrived, Mei Zhiyan had already arrived, and had waited for her for a long time.

"It's almost time to cultivate, let's go in and have a look." While saying this, Gu Li took Mei Zhiyan, changed into an isolation gown in the compartment outside the laboratory, and walked in.

Lifting the lid of the petri dish, Gu Li couldn't help but laugh.

What she saw was exactly what she had imagined, a thick layer of penicillium growing on the medium.

"Not bad." Gu Li said.

She opened another petri dish and saw that the staphylococci had been cultured as well.

"Now, we can move on to the next step." Gu Li said as she took out bottles, funnels, cotton, and other things.

"Come and help me," she said to May, "put this cotton in the funnel, and then put the funnel in the bottle." Be careful to wear gloves and do not let your skin touch the experimental equipment during the whole process. ”

"Okay", Mei Zhiyan agreed, and did as she asked.

Gu Li picked up the petri dish of Penicillium and poured all the Penicillium and culture medium into the funnel.

The funnel contains the filter foam, which only allows the liquid to pass through, and the impurities are left on the filter.

Mei Zhiyan was on the side, carefully observing and taking notes.

"Do you want all this green mold?" He asked, confused.

He also thought that it was these Penicillium that he wanted to leave behind, but he didn't expect the truth to be diametrically opposed.

"No," Gu Li replied, "Penicillium has been integrated into the culture medium, and these filtered out are actually impurities." ”

"Alright, bring me the vegetable oil."

Gu Li took the vegetable oil from Mei Zhiyan's hand, poured it into the solution that had just been filtered, and stirred.

After stirring, she poured the aqueous solution into a special bucket. There is a small opening under the barrel, and the small mouth is plugged with a wooden stopper.

"What's next?" Mei Zhiyan drew all these experimental devices on paper, and added words on the side to make it easier to understand.

"Purify," Gu Li replied, "You'll be able to see later, this aqueous solution will be layered." ”

As she said this, she glanced at the notebook in Mei Zhiyan's hand.

He remembered it very carefully, and if she was in her previous life, she was definitely an out-and-out scholar.

After a few moments, the aqueous solution in the bucket was divided into three layers.

"Come and see." Gu Li shouted to Mei Zhiyan.

Mei Zhiyan leaned over and listened to her say: "The top layer is a fat-soluble substance, that is, it can be dissolved in oil. The middle layer is an insoluble substance, which is insoluble in grease and water, so it is suspended in the middle. ”
