Chapter 207: The test begins

It's okay to marry three beautiful women as wives at once, but the identities of these three women are more noble than the other.

The saint daughter of the Yin-Yang family, the helmsman of the future Yin-Yang family, the daughter of the prime minister and the favorite daughter of the First Emperor.

However, everyone will only envy, not jealousy.

Because they felt that it was the third daughter who matched Qin An, not Qin An, who matched the third daughter.

They think that with Qin An's ability, any kind of woman can be found.

Qin An ran to the third girl, took the third girl's hand, and said, "It's okay for you guys to be fine, have you got a pox?" If not, I'll let Lao Xia help you get pox."

When the three daughters of Yingyin heard Qin An's concern, their hearts warmed.

"Xianggong, it has already been planted, and now the whole country is getting pox, and no one in the world will be afraid of smallpox in the future." Ying Yin Yan said.

Qin An nodded and said, "Then let's go." You've come just in time, I'm doing experiments right now, and if it works, we'll be able to make tractors to plow the land."

"Great. Then the people of the world will no longer need to plough their oxen." Ying Yin Yan said.

Zou Feng asked, "Xianggong, are you sure?"

Qin An smiled bitterly, "Not at all. The equipment here is too backward, everything is manually tested, and there is no accurate test data, so I don't know if this engine is qualified.

And I'm looking for alternatives to some of these materials, so I don't know if I can do it."

"Don't worry, my father is already helping you find what you need." Ying Yin Yan said.

She is telling Qin An that it doesn't matter if she fails, she is already busy looking for materials.

Qin An nodded and said, "Well, let's not worry about these for now, let's do experiments now, it's normal to fail, I never thought I would succeed once."

The third girl nodded.

At this time, Qin An's three disciples, Meng Yi, and Zhang Han also arrived, and they were only a few minutes away from the third girl.

"Sir." The five of them spoke in unison.

Qin An nodded at them and said, "It's good that you're back, Zhao Yun, you take Mondstadt and Li Xiao to gather the students and continue the class.

Students have been missing classes for so many days and should make up for it.

Lao Zhang and Meng Li stayed to see my new invention."

"The engine is finished?" Zhang Han asked excitedly.

He looked excited, and people who didn't know thought that this engine was not invented by Qin An, but by Zhang Han.

Qin An nodded and said, "That's right, it's done, but whether it can be used or not, I still don't have any confidence so far."

"What if you fail, Mr. often says, scientific research failures are the most common to see, where success comes without failure, and what failure is success for her mother." Zhang Han comforted.

Qin An rolled his eyes angrily and said, "What failure is success for her mother, obviously failure is the mother of success, okay."

Don't misinterpret the words of the great man, or you'll be laughed at."

"Not yet." Zhang Han said.

Meng Yi said: "A good sentence is the mother of success, there is no success without failure, because of failure and fear not to try, then he is destined to fail.

If he continues to challenge and summarize the reasons for his failure, then he will definitely succeed."

Qin An bowed his head and said, "Meng Li, that's good, it's summed up so quickly.

This sentence can be applied to any industry, especially in the industry of scientific invention, even if inventing something can be successful at one time, it does not mean that it is the most perfect.

Science can continue to improve, for example, the plough, the straight plough was used in the past, and now the curved plough is used, and there will be a tractor ploughing in the future, and there will be a cultivator all-in-one machine, and the speed will be faster.

On the land in the village, it only takes two days to harvest all the grain with the harvester outside.

Then, in two more days, with the all-in-one cultivator, you can plough the land and plant it at the same time."

"Sir, what you said is too much for me to believe." Meng Yi said, "But I still believe in Mr.'s words, and I even believe that it won't be long before Mr. can achieve this one by one."

"Thank you for your trust." Qin An smiled, "Okay, let's just watch here, don't get too close." Any experiment is dangerous."

"Xianggong, you have to be careful." Ying Yin Yan said with concern.

The other two daughters also showed concern.

Qin An smiled and said, "Don't worry, I made the thing, and I will control it."

Afterwards, Qin An asked everyone to wait twenty meters away, and he ran to the engine and said to the children of the Mo family and the children of the public loser who had been waiting for a long time, "Fill with diesel." ap.

"No." The disciple of the Mo family with the diesel fuel immediately responded.

He then walked up to the engine with diesel and poured it into the engine until the engine's tank was almost full.

"Sir has already filled 90% of the diesel." The Mo family disciple who was filled with diesel fuel spoke.

Qin An nodded, then asked everyone to step back ten meters, walked to the tractor by himself, used an iron rod, reached into the switch port of the engine, and then began to rotate hard.

"Flutter, flutter......"

The sound of the engine began with a slow turn, and soon became a rapid turn.

With the rapid rotation of the engine, Qin An immediately threw away the iron rod in his hand and quickly retreated ten meters, coming to the middle of the Mo family disciples and the male loser disciples.

"Sir." Everyone shouted at the same time, as if asking what was going on.

Qin An said, "Now that the engine has started, now you can make a record, from the sound, speed, and time.

I want to know if the sound of the engine has changed halfway through, and how long a tank of oil can start.

The most important thing is whether there will be abnormal noise in the middle of the engine, if there is abnormal noise, then there may be danger.

That's when we need to do an inspection.

If there is no abnormal noise, then the engine is okay. You can proceed to the second step of the test and turn off the flame halfway.

Then turn it on, turn it off, turn it on, turn it on, and repeat it again and again, thousands of times, if it can still be used, it means that the engine is qualified."

The disciples of the Mo family and the Gong Loser family all listened attentively to Qin An's explanation.

The three daughters of Yingyin Yan and Meng Yi, who were twenty meters away, were all excited, because the engine was moving, although they were twenty meters away, they could still hear the sound of the engine running.

"Great." Li Yanran said, "Xianggong's invention has succeeded."

Ying Yin Yan nodded excitedly and said, "Mmmmmm...... Xiang Gong's invention is successful, that is, Xiang Gong has completed his father's task."
