in the garden.

Bai Feng looked at Cao Jie's still beautiful face and couldn't help holding her in his arms.

"Marrying a wife like this, what can a husband ask for! I'm so happy!"

When Cao Jie heard this, his ears couldn't help but turn red.

"Being able to marry your husband, Ji'er is also very happy!"

Then Cao Jie said in Bai Feng's arms.

From Daqin to the present, Cao Jie believes that he is the happiest woman in the world.

Bai Feng not only loves and respects himself, but also allows himself to participate in all aspects of his career.

Today, Cao Jie can be said to be an indispensable help for Bai Feng.

And all of this is not because Cao Jie is Cao Cao's daughter, the princess of Great Wei.

Just because Bai Feng loved her, trusted her, and gave full play to her abilities.

No matter it is a noblewoman in Hanzhong, a noblewoman in Yizhou, or even a noblewoman in Yecheng, they all take being Cao Jie as an example.

A woman can hold up half the sky, which is the best interpretation of Cao Jie.

After spending a moment in the garden, the two returned to their room to rest...

The next day, the R&D center.

The craftsmen of the steam engine production line are now gathering in the open space outside the R&D center.

In the open space, Geng Zhuzi and Li Tiedan, Wang Gang, Xu Dali and other craftsmen were debugging the steam train.

Today is the second test run of the steam train.

Bai Feng also just arrived at the R&D center, and they just haven't finished debugging.

Another half an hour passed.

During this period, the craftsmen of the steam engine production line were constantly discussing the second test run of the steam train.

"Hey, Lao Zhu, you said that if this steam train is used to pull people, how much can it pull?"

"I think at least 20 or 30 people can be pulled, after all, such a big iron guy!"

"Twenty or thirty people? I can't see more than that! It should be able to pull fifty or sixty people!"

"I really want a steam train!"

The craftsmen chatted, and the topics began to become varied.

Geng Zhuzi and others finally completed the final debugging before the test drive.

"Hanzhong Hou, you can already."

Then Geng Zhuzi said to Bai Feng.

"Okay, let's get started!"

Bai Feng didn't get on the train this time. The control and testing of the steam train were all done by Geng Zhuzi, Li Tiedan, Wang Gang, and Xu Dali.

After the whistle sounded, the steam train began to move.

The other craftsmen who were talking about it, like Bai Feng, focused their attention on the steam train in motion.

In Bai Feng's eyes, the start-up time of the steam train was obviously much faster than the first test run.

This shows that the improved steam engine newly installed by Geng Zhuzi and others for the steam train has a very obvious effect of power improvement.

Then I saw the steam train speeding up continuously on the rails.

Because the rails used for the test run are circular, we can see that the entire steam train is going around in circles faster and faster.

The tiller in the cab felt that one side of the steam train was slightly off the track, and this stopped the continued acceleration.

Bai Feng felt that the speed of the steam train was about 40 kilometers.

Well, it's faster than riding an electric bike, but a lot worse than a motorcycle.

But this speed is much faster than that of a horse-drawn carriage.

After all, if the carriage is too fast, the people in the carriage will first be unbearable because of the bumps.

At a speed of forty kilometers, Bai Feng was already quite satisfied.

Just because the distance of the rails used for the test run here is too short, it is not possible to hang the carriages for the steam train.

If you want to test how much weight the steam train can carry at most, you have to go to the mine to test it.

The tiller in the cab was satisfied with the current state of the steam train.

Compared with the first test run, this time the improved steam train not only has more power, but also uses less coal.

The coal originally prepared could make the steam train run for an hour, but now it has run for a quarter of an hour, but the consumption of coal is only two-thirds of the previous amount.

Next, Gengzhu began to test the braking performance of the steam train.

After pulling down the brake lever, the screeching sound of the entire steam train rubbing against the rails reached Bai Feng and the surrounding craftsmen.

So everyone covered their ears.

After a while, the steam train came to a complete stop.

Only then did everyone put down their hands covering their ears.

"This time I ran much faster than the last time!"

"Hmm, at least twice as fast!"

"The carriage is no longer as fast as the steam train!"

"I really want a steam train!"

The craftsmen on the sidelines were amazed at the speed of the steam train that was improved again.

Then, Geng Zhuzi started the steam train again, and began to test the operation of each control lever on the steam train one by one to see if immediate feedback could be obtained.

It was not until all the coal that was going to be used for the test run was used up that the test run came to an end.

The unfinished artisans returned to the steam engine production line again to start work.

After Geng Zhuzi got down from the cab of the steam train, he began to report the results of this test to Bai Feng.

"...In general, the power has been greatly improved compared to before, and the increase has been about doubled. Also, the consumption of coal is less, about one-third less... ."

"And the feedback results of each lever have become more sensitive..."

After reporting the results of this test drive to Bai Feng, the smile on Geng Zhuzi's face was very obvious.

He was very satisfied with the improved performance of the steam train.

Although there is still a lot of room for improvement in the current steam train, every time the performance is improved, Gengzhuzi has a feeling that his own children continue to grow.

After listening to Geng Zhuzi's report~lightnovelpub.net~, Bai Feng was also very satisfied with Geng Zhuzi, as well as Li Tiedan and Wang Gangneng, the craftsmen who participated in the manufacture and improvement of steam trains said:

"The test results this time were much better than I expected."

"The mine is now using nitro/glycerin explosives for mining, and the rails are halfway laid."

"The real place to test the performance of steam trains is in the mines."

"I believe that your efforts can make the steam train shine in the mine!"

Geng Zhuzi, Li Tiedan, Wang Gang, Xu Dali and other craftsmen heard the words, and their eyes were filled with excitement.

The steam train is finally no longer just in front of everyone during the test run, it is finally about to give full play to the value it was made!

"Send the steam train to the mine tomorrow. Let's take a look at the load capacity of the steam train."

Bai Feng explained to Geng Zhuzi.
