The sky was bright and bursts of laughter resounded throughout the Xiaoze River. The villagers who went to Kunnan to work by boat passed the hospital dock.

After more than half a year of continuous struggle, the people of Kunshan not only did not show any fatigue, but their morale became increasingly high. They sang all the way while working, and were filled with joy from the bottom of their hearts.

With their vigorous efforts, just in October, Kunnan's national epidemic prevention campaign came to an end. A large number of civilians moved into the preparations for the third phase of the water conservancy project, and the Kunshan County winter battle has quietly begun...

The news of the serious injury of the governor was strictly blocked, so the people naturally had no way to know. They only knew that Jiangnan Hospital suddenly stopped treating for one day yesterday, which disappointed many patients who had signed up.

The people were speculating about this, and they didn't know what happened, which forced the proud Jiangnan Hospital to close down.

Until they saw the officials ships with various banners such as the governor's yamen, the governor's yamen, and Shanghai County on the dock, they finally came to the conclusion that the officials came to see a group of doctors.

"Bah, these dog officials know how to harass us Kunshan!" The people pointed at the official boats angrily, and were unhappy that they used their privileges to occupy Jiangnan Hospital.

But when they saw the beautiful Science Number that was too eye-opening to move, they stopped on the dock, the scolding came to an abrupt end.

At such an early age, 80% of the yamen are still sleeping on the boat, which can't affect his health...

On Science Number.

Qiaoqiao quietly pushed open the master bedroom door.

Then I saw Zhao Hao and Ma Xianglan leaning against their heads, sleeping soundly on the table.

The ground was covered with waste paper, telling the hard work of the two last night.

Qiaoqiao felt distressed and a little regretful when she saw it. Who made me unable to stay up to the night and fell asleep in the first half of the night?

Otherwise, I could sleep with the young master like Sister Ma.

Hello, my faces are all sticking together!

Qiaoqiao stretched out her hand and wanted to push the two of them away.

But Ma Xianglan stretched and sat straight.

"Ah, why are you asleep?"

Then, under Qiaoqiao's suspicious gaze, she sorted out her slightly scattered clouds, naturally stood up, gently rubbed Zhao Hao's shoulder and said:

"Young Master, go to bed."

Seeing her calm look, Qiaoqiao couldn't help but blame herself secretly. How could I think of Sister Ma at the fox Meizi? It's really inappropriate.

We need to reflect carefully.

Unfortunately, Mr. Zhao didn't even get into bed.

Qiaoqiao just served him to wash his face and was coaxing him to have breakfast, but Zhao Shizhen and Zhang Jian came.

"Master, what happened?" The two of them received a notice from Xiwa last night, saying that Zhao Hao had something urgent to ask them to come back quickly.

They left Xishan Island at the fourth update and arrived at this moment.

As soon as he saw them, Zhao Hao was no longer sleepy and asked Qiaoqiao to serve the two disciples. He chatted while eating:

"Lin Zhongcheng was in a fire and has been unconscious yet. What should our science school do for him."

"But Master, we won't cure diseases." Zhang Jian whispered with a delicious sip of shrimp porridge.

"The development of medicine has reached a bottleneck. If you want to make a breakthrough, you have to rely on the development of science." Zhao Hao shook his head flatly and said, "Today we are going to try to do something epoch-making."

"What's the matter?" The two disciples' eyes immediately shone.

"Make oxygen." Zhao Hao said in a deep voice: "The current threat to Lin Zhongcheng's life is the toxicity that penetrates the brain. How do you talk about this disease in science?"

"Carbon monoxide poisoning." This is the knowledge point in "Natural Knowledge", and the two disciples of the big touch naturally opened their mouths.

"After carbon monoxide binds to hemoglobin, hemoglobin loses its oxygen delivery function, causing hypoxia in the body and damages the human brain tissue."

"So at this time, oxygen delivery should be treated." Teacher Zhao said.

"Oxygen delivery?" Zhang Jian asked in confusion: "Isn't there oxygen everywhere in the air?"

They conducted air composition tests in the Beijing Science Exhibition Hall, knowing that air is composed of a variety of gases, and even knowing that oxygen accounts for about one-fifth of the total air volume.

"For patients who treat their health, the oxygen content in the air is still too low." Then Teacher Zhao blatantly declared: "So we need to extract pure oxygen!"

"Where do you extract it?" the two disciples asked in unison.

"Here." Zhao Hao said, picking up the crystal cup on the table and pouring out some clean water.

"Water molecules are composed of two hydrogen atoms and one oxygen atom. Oxygen and hydrogen can be obtained through electrolysis!" Teacher Zhao revealed the answer.

"Electrolysis?" the two disciples asked again: "Is it using electrolysis?"

Of course, the most basic electrical knowledge has been introduced in "Natural Knowledge".

Such as lightning, static electricity, and the relationship between electricity and magnetism are involved.

"Not bad." Mr. Zhao nodded.

"Did you use metal coils to rotate in a magnetic field to generate electricity?" Zhao Shizhen asked immediately.

"Uh, yes..." Mr. Zhao's mouth twitched, and a few drops of milk leaked out.

"Then Master, how do you distinguish between hydrogen and oxygen?" Zhang Jian asked.

"Oxygen precipitates from the positive electrode, and hydrogen gas precipitates from the negative electrode." Mr. Zhao replied.

"That's simple." Zhang Jian and Zhao Shizhen looked at each other and smiled, the latter said: "Insert two bamboo tubes into the water, one on the positive electrode, and the other on the negative electrode, and then connect the pig urine bubble to the other end of the bamboo tube."

"Since there are twice as many hydrogen atoms in water than oxygen atoms, the faster the one collects gas is hydrogen, and the slower the one is oxygen." The former asked again with a serious look: "Right, Master?"

"It can be said that..." Mr. Zhao smacked his lips and took the troubles of a bunch of genius disciples. Who can understand what he said?

You can understand it at a glance, and you can also answer it quickly and learn from it. This makes the teacher always feel that his intelligence is being ruthlessly crushed.

Alas, I'm so helpless...

Mr. Zhao had to try his best to maintain the dignity of his master and said: "The hydrogen produced by electrolysis is twice the volume of oxygen."

"Then can't we make hydrogen balloons?" The two disciples were completely excited: "You can also synthesize ammonia and prepare hydrochloric acid!"

"Stop, stop, stop, stop, stop, stop," Teacher Zhao said in a daze: "Where did you learn this?"

"Didn't the teacher send us the textbooks for "Elementary Chemistry"?"

"Yes, the teacher will definitely not waste time explaining such a simple thing, so we taught ourselves." The two inventors replied.

"I've done several experiments..."

"I call you crazy! I call you crazy!" Mr. Zhao was considered to have taken the opportunity to vent his anger... Oh no, it's just teaching the ignorant disciple a lesson.

"You are asking you to see if you're fine. Have you asked you to do the experiment?" He pounded the drum, and knocked the two of them hard on the head with chopsticks, cursing: "Do you know, how dangerous is chemistry? Do you know if you can't do it well and you'll lose your life!"

"We are wrong, Master..." The two disciples quickly admitted their mistakes.

Mr. Zhao then put down his chopsticks.

He was so comfortable.
