The sky was bright, and bursts of laughter resounded through the Xiaoli River, where the people who went to work in Kunnan passed by the hospital dock by boat.

After more than half a year of continuous struggle, the people of Kunshan not only did not show fatigue, but their morale became higher and higher.

Thanks to their energetic efforts, the nationwide anti-epidemic campaign in Kunnan has come to an end in October. A large number of people have transferred to the preparatory work of the third phase of the water conservancy project, and the winter battle in Kunshan County has quietly begun......

The news of the governor's serious injury was tightly sealed, and the common people naturally had no way of knowing. They only knew that yesterday Jiangnan Hospital suddenly closed for a day, which disappointed many patients who had registered.

The people speculated a lot about this, and they didn't know what was going on, so that the proud Jiangnan Hospital had to close down.

It wasn't until they saw the official ships on the wharf with various flags such as the governor's yamen, the prefect's yamen, and Shanghai County that they finally came to the conclusion that they thought they were reliable—it turned out that the officials had come to see a doctor collectively.

"Phew, these dog officials, they know how to harass us Kunshan!" The people indignantly pointed at those official ships, unhappy that they used their privileges to occupy Jiangnan Hospital.

But when they saw the beautiful Science that couldn't take their eyes off it, and it was also parked on the dock, that the scolding stopped abruptly.

So early, Ya Nei Bacheng is still sleeping on the boat, but it can't affect his body......

~~

Science.

Qiaoqiao quietly pushed open the master bedroom hatch.

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

The waste paper ball is all over the ground, telling the hard work of the two last night.

Qiaoqiao looked distressed and a little regretful, who let himself stay up all night and fell asleep in the first half of the night.

Otherwise, you can be like Sister Ma, who slept with her son in the name of righteousness.

Hey, the faces are all together!

Qiaoqiao stretched out her hand, trying to push the heads of the two people away.

saw Ma Xianglan stretch and sit up straight.

"Ah, why did you fall asleep?"

Then under Qiaoqiao's suspicious gaze, she straightened out her slightly scattered cloud temples, naturally got up, gently rubbed Zhao Hao's shoulders and said:

"Childe, go to bed."

Seeing her calm appearance, Qiaoqiao couldn't help but secretly blame herself, how could I think of Sister Ma as a fox, it's really undeserved.

Be introspective.

~~

It's a pity that Zhao Gongzi didn't get to bed in the end.

Qiaoqiao had just waited for him to wash his face, and was coaxing him to have breakfast, when Zhao Shizhen and Zhang Jian came.

"Master, what's going on?" The two received a notice from Xiwa last night, saying that Zhao Hao had something urgent and asked them to come back quickly.

The two of them left Xishan Island in the fourth watch, and finally arrived here in a hurry.

As soon as he saw the two of them, Zhao Hao was not sleepy, and asked Qiaoqiao to serve food to the two disciples. Chatting while eating:

Lin Zhongcheng suffered a fire and is still unconscious. We should do something for him. ”

"But Master, we won't heal." Zhang Jian took a sip of delicious shrimp porridge and whispered.

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

"What's the matter?" The two disciples' eyes lit up.

"Make oxygen." Zhao Hao said in a deep voice: "At present, what threatens Lin Zhongcheng's life is the poison of tobacco into the brain, how can this disease be scientifically said?" ”

"Carbon monoxide poisoning." This is the knowledge point in "Little Knowledge of Nature", and the two big touch disciples naturally come when they open their mouths.

"After carbon monoxide combines with hemoglobin, hemoglobin loses its oxygen delivery function, causing hypoxia in the body, which can damage human brain tissue."

"That's why it's time for oxygen therapy." Just listen to what Mr. Zhao said.

"Oxygen?" Zhang Jian was puzzled and asked, "Isn't there oxygen everywhere in the air?" ”

They have done a test to determine the composition of air in the Beijing Science Exhibition Hall, and they know that air is composed of a variety of gases, and even know that oxygen accounts for about one-fifth of the total amount of air.

"The oxygen content in the air is still too low for treating patients." I heard Mr. Zhao brazenly declare: "So we want to extract pure oxygen!" ”

"Where?" The two disciples asked in unison.

"Here." Zhao Hao said, picked up the crystal cup on the table, and poured out some water.

"Water molecules are made up of two hydrogen atoms and one oxygen atom, and oxygen and hydrogen can be obtained by electrolysis!" Mr. Zhao unraveled the mystery.

"Electrolysis?" The two disciples asked again, "Is it decomposition with electricity?" ”

In "A Little Knowledge of Nature", of course, the most basic knowledge of electricity has also been introduced.

Things like lightning, static electricity, and the relationship between electricity and magnetism are all involved.

"Not bad." Zhao Gongzi nodded.

"Is it a metal coil that rotates in a magnetic field to generate electricity?" Zhao Shizhen then asked.

"Uh, yes......" The corners of Zhao Gongzi's mouth twitched, leaking a few drops of milk.

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

"Oxygen is precipitated from the positive electrode, and hydrogen is precipitated from the negative electrode." Zhao Gongzi replied.

"Then it's easy." Zhang Jian and Zhao Shizhen looked at each other and smiled, and the latter said: "Insert two bamboo pipes into the water, one buckle on the positive electrode and one buckle 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 as oxygen atoms, the fastest way to collect gas is hydrogen, and the slower is oxygen." The former asked with a serious face, "Right, Master?" ”

"So to speak...... "Zhao Gongzi smacked his lips, taking in the distress of a group of genius disciples, who understands when he says it?

A little bit is thorough, as soon as you say it, and you can also rush to answer and draw inferences, so that the teacher always feels that his intelligence is being ruthlessly crushed.

Hey, that's so helpless......

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

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

"Stop, stop." Teacher Zhao was dumbfounded and said, "Where did you learn this?" ”

"Didn't the teacher give us the textbook of "Elementary Chemistry"?"

"Yes, the teacher will definitely not waste time explaining such a simple thing, so we will study on our own." The two inventors replied.

"I've done several experiments......

"I'm mad for you! I'm mad for you! "Zhao Gongzi can be regarded as having seized the opportunity to vent his anger...... Oh no, it's a lesson for the ignorant disciples.

"As a teacher, let you see if it's okay, let you do experiments?" As if beating a drum, he hit the heads of the two with chopsticks and scolded: "Do you know, how dangerous chemistry is?" Do you know that if you don't get it right, you will lose your life! ”

"We were wrong, Master......" The two disciples hurriedly admitted their mistakes.

Zhao Gongzi put down his chopsticks at this time.

He meowed, and he was comfortable.
