That cold drying equipment is still floating on the Atlantic Ocean...

Three or four months.

King Zheng Long is afraid he won’t be able to wait for that time.

Su Xuezhi was silent for a moment, thanked her, slowly put down the phone, hung up, and then fell into deep thought.

If you can’t count on professional cold drying equipment, you can also use local methods to reliably reliably.

Su Xuezhi was thinking quickly.

Freeze-drying is nothing more than two methods: chemical and physical. On the premise that the faster the time is, the better, the chemical drying method is obviously more feasible.

Desiccant is not a problem, calcium sulfate can be used.

However, calcium sulfate alone is not enough, and there is also a supporting drying equipment.

Is it possible to let professionals cooperate and make a simple and practical small drying equipment as soon as possible?

Su Xuezhi felt that it was not impossible.

The only question is, for a moment, where can professionals who are proficient in power machinery go?

At this time, the phone that had just been put down suddenly rang.

She felt that it must have been called back by Fu Mingcheng, so she picked it up.

Her premonition was indeed correct, it was indeed Fu Mingcheng who called back.

He asked her what was wrong.

His tone sounded hesitant.

"To be honest, I was surprised when I received your call just now. Actually, there is a saying that I wanted to tell you a long time ago, but I was afraid of disturbing you..."

On the phone, he paused for a moment, and finally seemed to have made up his mind and spoke again.

"Xuezhi, you rejected me last time. I told you that if you want, I will be very willing to continue to be your friend. It's true. I feel like something happened to you. I'm sorry, I really can't get it to Hong Kong early for the equipment you need, but if you have difficulties, you can tell me and see if I can do my best. This is my truth."

His tone was very sincere.

Su Xue thought for sure.

The Fu family's commercial status and influence in the north are beyond doubt. After Fu Mingcheng took over the Fu family, the industry began to expand into textile and other manufacturing industries.

In other words, Fu's deals with various downstream suppliers and personnel from different industries.

Who is more suitable to find such a professional person?

Su Xuezhi no longer hesitated and asked: "Do you know the practitioners of electric machinery? You are right. I really have some trouble. The laboratory urgently needs cold drying equipment."

She described her thoughts to him.

Fu Mingcheng thought for a while and said, "There is no big problem. I have acquired a power plant and there should be an engineer in this field. I will contact you as soon as possible."

Su Xuezhi thanked him.

"A small matter. Wait for my news and I will be able to reply to you tomorrow."

After Su Xuezhi called out, she breathed a little relieved and came out. She was sleepy and wanted to see the growth of the latest batch of molds, so she walked towards the laboratory.

It was almost eleven o'clock in the evening, and the school was dark and silent.

Su Xuezhi entered the experimental building and turned on the corridor lights. Suddenly, he heard a slight clicking sound from the front, with a little strange noise.

In order to save electricity, the electric lights installed in the corridor are very low in wattage and emit very dark light, which is only enough for lighting.

She stopped and looked forward. There was nothing unusual. The silence in her ears returned to silence. She thought she had heard it wrong, so she continued to walk along the familiar corridor, in the shadowy incandescent lights, towards her laboratory. When she arrived at the door, she took out the key and was about to open the door, she felt a gust of night wind pouring in.

Her hands stopped, turned her head, and looked at the window across the corridor.

It has been raining frequently at night recently. In order to prevent water from pouring back, the windows in the corridor also need to be closed.

Su Xuezhi was impressed that when she and Dr. Yu left tonight, she confirmed that the window was closed, and the pins used to fix the windows on the inside were also locked.

But at this moment, a window was opened, and the night wind blew in from the open window.

You won't be able to open the pin.

And at night, no one else would come to the laboratory here except her and Dr. Yu.

Did Dr. Yu come here again in the evening and open the window?

Su Xuezhi remembered the slight strange sound he heard when he came in just now.

She walked to the window and looked out.

Opposite the window is the school’s library. At this time, it is naturally dark and there is no one to see.

She closed the window and reinserted the latch.

The next morning, Dr. Yu came to the laboratory and Su Xuezhi asked him if he had been back last night.

Dr. Yu said no.

Su Xuezhi walked out, opened the window himself, stared at the windowsill, and when he was in a daze, a classmate came and called out, saying that Fu Mingcheng was here and was waiting for her outside.

Su Xue came back to her senses and hurried out. Sure enough, she saw Fu Mingcheng standing outside the ship king memorial room next to the hall of the experimental building and walked over quickly.

Fu Mingcheng also came up to meet him.

I haven't seen him for half a year. It should be because of the operation that caused him to be seriously injured. Although his body is gradually recovering, he still loses a lot of weight. However, his eyes are still so bright and his face is also a familiar smile, which looks similar to what Su Xuezhi thinks of him.

Su Xuezhi spoke and asked him how he was doing now. Fu Mingcheng smiled and said, "The principal just had a latest physical examination on me last week, and there was no problem."

Fu Mingcheng made Su Xuezhi feel very relaxed, and there was no embarrassment of meeting she had originally worried about.

She asked him to come in and sit.

Fu Mingcheng said: "No need. You're in a hurry, so I'll tell you that I found someone. I was a mechanical engineer in the power plant after studying in engineering in my early years. I'm very experienced. I told him about your ideas. He should be competent, but he needs to design drawings first. You can discuss your ideas with him. If you are convenient, I can take you to see him now."

Su Xuezhi immediately went to meet the engineer named Yang and explained his idea. The engineer improved it. A few days later, the drawings came out. Then, the workers worked day and night, and in just one week, they made a simple vacuum dryer.

Su Xuezhi got the dryer and took the last step.

After the test proved feasible, she and Dr. Yu filled all the remaining extract into several ampoules. After freezing, the ampoule was connected to the dryer, keeping the temperature of the ampoule at minus 21℃ and pumping. After twenty-four hours of continuous work, the finished product finally came out and a dry drug that could be stored at room temperature was obtained.

Time is no longer waiting for anyone.

Su Xuezhi collected this precious medicine and went to the principal to ask for leave, saying that he wanted to go back to his hometown to visit a seriously ill relative. The principal allowed the leave.

Ding Chunshan was also extremely efficient in his work. At this time, he came over and informed Su Xuezhi that there was already a place that met her requirements, located in the western suburbs of the capital.

It was originally the arsenal of the Qing Dynasty. It was located in the mountains and was secretly located. It is now abandoned, but the site is all intact and can be renovated according to her requirements.
