As the sky brightened, bursts of laughter echoed across the Xiaoshan River. They were the laborers going to work in Kunnan, passing by the hospital pier by boat.

After more than half a year of continuous fighting, the people of Kunshan have not shown any signs of fatigue. Instead, their morale has become increasingly high. They sing all the way to work and are happy from the bottom of their hearts.

Thanks to their energetic efforts, the nationwide epidemic prevention campaign in Kunnan came to an end just after October. A large number of civilians turned to the preparations for 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 strictly blocked, so the common people naturally had no way of knowing. They only knew that Jiangnan Hospital suddenly stopped operating for a day yesterday, leaving many patients who had registered disappointed.

The people were speculating about this, wondering what had happened that forced the proud Jiangnan Hospital to close down.

It was not until they saw the official ships at the dock with various flags of the Governor's Office, the Prefectural Government, Shanghai County, etc., that they finally came to what they thought was a reliable conclusion - it turned out that the officials had come to see a doctor collectively.

"Bah, these damn officials only know how to harass us in Kunshan!" The people pointed at the official ships angrily, unhappy that they were using their privileges to occupy the Jiangnan Hospital.

But when they saw the beautiful and eye-catching Science also parked at the dock, their cursing stopped abruptly.

It’s so early, Yanei is probably still sleeping on the boat, we can’t let it affect his growth…

On board Science.

Qiaoqiao quietly pushed open the door of the master bedroom.

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

The ground was littered with waste paper, telling of the two people's hard work last night.

Qiaoqiao felt both distressed and regretful when she saw this. It was her own fault that she couldn't stay up late and fell asleep in the first half of the night.

Otherwise, you can also sleep with the young master like Sister Ma did.

Hey, their faces are stuck together!

Qiaoqiao stretched out her hand and tried to push the two men's heads away.

But Ma Xianglan stretched and sat up straight.

"Ah, why did you fall asleep?"

Then, under Qiaoqiao's suspicious gaze, she straightened her slightly messy hair, stood up naturally, gently rubbed Zhao Hao's shoulders and said:

"Sir, go to bed."

Seeing her calm look, Qiaoqiao couldn't help but blame herself secretly. How could I have thought of Sister Ma as a vixen? It was really wrong.

You should reflect on this carefully.

Unfortunately, Mr. Zhao never got to sleep with her.

Qiaoqiao had just helped him wash his face and was coaxing him to eat breakfast when Zhao Shizhen and Zhang Jian arrived.

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

They left Xishan Island at four o'clock in the morning, and finally arrived at this moment after hurriedly rushing.

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

"Lin Zhongcheng was caught in a fire and has been in a coma ever since. We in the science department should do something for him."

"But Master, we don't know how to cure diseases." Zhang Jian took a sip of the delicious shrimp porridge and said in a low voice.

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

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

"Produce oxygen." Zhao Hao said in a deep voice: "The current threat to Lin Zhongcheng's life is the entry of tobacco poison into his brain. How does this disease explain it scientifically?"

"Carbon monoxide poisoning." This is a point of knowledge in "A Brief Knowledge of Nature", so the two great disciples could easily answer it.

"When carbon monoxide combines with hemoglobin, it causes hemoglobin to lose its oxygen transport function, causing the body to be hypoxic and damaging human brain tissue."

"So oxygen therapy should be given at this time." Teacher Zhao said.

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

They conducted experiments to measure air composition in the Beijing Science and Technology Exhibition Hall and learned that air is composed of many gases, and even that oxygen accounts for about one-fifth of the total air volume.

"The oxygen content in the air is still too low for treating patients." Then Teacher Zhao declared: "So we have to extract pure oxygen!"

"Where can we extract it from?" the two disciples asked in unison.

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

"The water molecule is 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 decomposition using electricity?"

Of course, the most basic electrical knowledge has also been introduced in "A Brief Introduction to Nature".

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

"That's right." Master Zhao nodded.

"Is it using metal coils rotating in a magnetic field to generate electricity?" Zhao Shizhen asked immediately.

"Uh, yes..." Mr. Zhao twitched the corner of his mouth and a few drops of milk leaked out.

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

"Oxygen is released at the positive electrode, and hydrogen is released at the negative electrode." Mr. Zhao replied.

"Then it's easy." Zhang Jian and Zhao Shizhen smiled at each other, and the latter said, "Insert two bamboo tubes into the water, one on the positive pole and the other on the negative pole, and then connect the pig bladder to the other end of the bamboo tube."

"Since there are twice as many hydrogen atoms as oxygen atoms in water, the gas that collects faster is hydrogen, and the gas that collects slower is oxygen." The former asked seriously, "Right, Master?"

"You could say that..." Master Zhao smacked his lips. Who would understand the troubles of accepting a group of talented disciples?

He understands things quickly, knows how to speak as soon as he is told, is also good at answering questions quickly and drawing inferences from what he has learned. The teacher always feels that his or her intelligence is being ruthlessly crushed.

Oh, so helpless...

Master Zhao had to do his best to maintain his dignity as a teacher and said, "The volume of hydrogen produced by electrolysis is twice that of oxygen."

"Then can we make hydrogen balloons?" The two disciples were completely excited: "We can also synthesize ammonia and prepare hydrochloric acid!"

"Stop, stop, stop." Teacher Zhao was stunned and asked, "Where did you learn this from?"

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

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

"I have done several experiments..."

"I told you to be crazy! I told you to be crazy!" Master Zhao finally got the chance to vent his anger... Oh no, it was to teach his ignorant disciples a lesson.

"Did your teacher tell you to just watch and do the experiment?" He hit the two men's heads hard with chopsticks like beating a drum, and scolded, "Do you know how dangerous chemistry is? Do you know that if you don't do it well, you will lose your life!"

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

Only then did Master Zhao put down his chopsticks.

Damn, it feels so good.
