Days passed.

The decree abolishing the crown prince of Li Chengqian was issued.

During the whole process, Li Chengqian did not show his face at all and did not resist at all.

It's just that on the day the holy decree was issued, he moved out of the East Palace and made an appearance in a palace in Chang'an City.

Then, a piece of news came back, causing people to reduce their discussion of Li Chengqian.

That is, the Lingnan rebellion has been successfully quelled, and the army has returned.

It was a few days later.

The army has finally returned.

Fang Yuan and the others gathered at the gate of the city to welcome the return of Xue Bowu and the others.

Under the watchful eye of the public, Hou Junji, the secretary of the military department, rode a war horse and walked in the front.

Behind him were some generals, and then Li Danqiu's sisters and brothers, Qin Huaiyu and others.

Among them, there is Xue Bowu.

When Xue Bowu followed, he was an ordinary young general, not even a young general.

"Brother, it's brother!"

"Fang Yuan, my brother has a future!"

Xue Jiaoyan is the happiest.

Although she doesn't understand war, she understands that she must have contributed a lot to being able to be in such a front team after returning triumphantly.

"Congratulations."

Fang Yuan smiled knowingly.

He really didn't misunderstand Xue Bowu.

This person is a natural general, and as long as he goes to the battlefield, he will definitely shine.

Compared to a few months, Xue Bowu looked much darker and more mature.

"Welcome heroes!"

"Welcome heroes!"

"Welcome heroes!"

The greeters began to cheer.

Wave after wave of voices can be heard throughout Chang'an City.

Not all of the great armies entered the city, but only those of the leadership level entered the city.

Except for Hou Junji and a few generals who needed to go to the military headquarters to report on their work, the others could go home when they arrived at a pick-up point.

"Brother!"

Xue Bowu just stopped.

Xue Jiaoyan rushed towards him.

I thought that the two siblings would have a warm hug.

But no one thought that when Xue Jiaoyan ran in front of Xue Bowu, she jumped up and knocked on Xue Bowu's head.

"Sister, it hurts."

Xue Bowu immediately covered his head with both hands, and tears flowed from the corners of his eyes.

"It's good to be back!"

Xue Jiaoyan's eyes became rosy.

Standing aside, he looked at Xue Bowu with a sigh.

"Fighting, welcome back."

Fang Yuan and the others also came over to welcome Xue Bowu's return.

Among so many people, Fang Yuan wanted to welcome a lot of people, but except for the Li family's sisters and brothers, everyone else was welcome.

However, the Li family sisters and brothers are still registering any information, and all the houses have not yet gone to the two of them.

"Hee-hee, thank you."

Xue Bowu said a little shyly.

"Fang Yuan, have you been promoted?"

Suddenly, a surprised voice rang out.

Xun Sheng looked over, it was Qin Huaiyu and Cheng Chumo.

But it wasn't just the two of them who walked towards Fang Yuan, but also their families.

"You're going to be promoted, aren't you?"

Fang Yuan smiled slightly.

There was a heavy hug between the two of them.

"You're rising so fast, we're both going to be jealous of you."

Qin Huaiyu's tone was a little sour.

When I first met Fang Yuan, Fang Yuan was just a small place.

Then he was promoted to the county magistrate of Chang'an County, and now he is already the head of the household department of the fourth product.

One step further, it's almost a very human minister!

With such a rapid promotion speed, it's really hard not to be jealous.

"It's just luck."

"It's not like you're really swordsmanship."

Fang Yuan said modestly.

"Luck is also a form of strength."

"Let's go home first, and then get together when we have time."

Qin Huaiyu said solemnly.

After saying goodbye to Cheng Chumo, Fang Yuan and Du Miaoyan, he left.

"That Qin Huaiyu shined in this battle of Lingnan and killed more people than me."

Xue Bowu said suddenly.

Looking at Qin Huaiyu's back, he rarely showed a serious look.

"Normal."

Fang Yuan was a little surprised.

But I don't think it's unacceptable.

It is rumored that Qin Qiong is the current number one fierce general.

But because his relationship with Li Shimin is not very good, and he has a lot of injuries on his body, he rarely shows up.

His son Qin Huaiyu obtained his true inheritance, so it would not be difficult to kill the enemy on the battlefield.

The battlefield does not rely on brute force, but also on stratagem.

Subsequently, Fang Yuan noticed that Li Danqiu's sister and brother walked out of the registration side.

"Let's go, let's go meet Li Danqiu's sister and brother."

Fang Yuan chuckled.

"Okay."

Du Miaoyan shook his head.

and Fang Yuan walked side by side towards Li Danqiu's sister and brother.

"Let's go, let's go too."

Hongxu Qingyao echoed.

So Xue Jiaoyan's sister and brother stopped talking about the old and walked towards Li Danqiu's sister and brother.

"Li Danqiu, Li Siwen, welcome back."

Fang Yuan said with a smile.

"Fang Yuan!"

"Are you coming to pick us up?"

Li Danqiu originally seemed to be a little lost.

But after seeing Fang Yuan, his expression suddenly became a lot more exciting.

Their sister and brother had no relatives in Chang'an City, and no one came to pick them up.

I didn't think there was anything, but I saw that everyone else had someone to pick up, but my sister and brother didn't, so I was a little disappointed.

"Or else?"

"Let's go, follow me back to the house, I've prepared a reception banquet for you."

Fang Yuan smiled enthusiastically.

"You have righteousness."

Li Danqiu smiled even more happily.

Li Siwen also smiled happily.

Immediately, several people chatted while walking, and mentioned Xue Bowu.

"Fang Yuan, let me tell you, you, the bodyguard, are not human at all on the battlefield."

"When he kills people, it's like cutting vegetables and melons, except for Qin Huaiyu, he kills the most people."

"You don't know, he has a nickname on the enemy's side, called the Vegetable Butcher!"

Li Danqiu pointed to Xue Bowu on the side and said.

The eyes were still shocked, full of shock.

Li Siwen also nodded meaningfully, admiring Xue Bowu very much.

"Vegetable melon butcher?!"

Fang Yuan and the others were a little surprised.

Xue Jiaoyan laughed even more, feeling ridiculous at this title.

Xue Bowu didn't speak, just scratched his head and smiled awkwardly and politely.

"Yes, they all made the other party scared."

"If General Hou hadn't persuaded those who weren't real enemies, he might have been happier to kill."

Li Danqiu nodded thoughtfully.

At the beginning, the Tang army fought bravely to kill the enemy.

The victory rate on the battlefield was very large, and the Tang army was a little tolerant.

In Hou Junji's words, the people on the Lingnan side are their own people, so they don't need to be too crazy to kill people.

So the war slowed down a little, and finally Lingnan surrendered, put down the chaos, and then came back.

"You two are pretty good too."

Xue Bowu finally spoke.

But he's not good at words, so that's all he needs.

In fact, Li Danqiu's sister and brother also performed very well on the battlefield.

In addition to not being as prominent as Qin Huaiyu and Xue Bowu, they are also the two more powerful among the young people.

After all, his father is Li Tao, and he has been on the battlefield again, and there is no difficulty at all in fighting a decisive battle with the Lingnan rebel army.

It didn't take long for everyone to return to Fangfu.

The Fang Mansion had already prepared a banquet to welcome the return of Xue Bowu and Li Danqiu's siblings.

This night, Li Danqiu's sister and brother stayed in Fangfu.

The three of them mentioned a lot of the situation in Lingnan.

said that it was barren, there were many mountains and forests, and the education was also very poor, and so on.

This night, everyone ate late before closing the stage.

"Husband, how do you think you're interested in Lingnan?"

Du Miaoyan snuggled into Fang Yuan's arms and asked softly.

Tonight, it was mainly Fang Yuan who asked about the situation in Lingnan.

Religion, culture, education, and so on.

"Over there by the sea."

"If you want to develop sailing, the location over there is very good."

Fang Yuan thought for a while and said.

In fact, Fang Yuan before crossing was a Lingnan person.

So I have a soft spot for Lingnan and even want to go back and see it.

But now Lingnan seems to be quite wild, and I am afraid that it is difficult to guarantee safety when I go back.

"Husband wants to develop sailing?"

Du Miaoyan was a little surprised.

Fang Yuan has a lot of industries in his hands.

Every industry is actually developing right now.

There are not many people who pay attention, after all, Fang Yuan is now a household servant, and the light is too much.

But if you take a closer look, you will find that every industry under Fountain is developing rapidly, and new products will be launched every time.

"It's just for later."

Fang Yuan shook his head and said.

In the future, we will promote the product to the world.

But that's later, and I don't know when it will be in the future.

The husband and wife spoke softly and talked for a long time before falling asleep.

Next.

Sun Simiao wanted to go to the Mojia Research Institute to have a look.

So Fang Yuan deliberately asked for leave and took Sun Simiao to the Mojia Research Institute.

Li Danqiu didn't know how to know, and he was noisy and wanted to follow.

So the three of them set off and hurried to the Mojia Research Institute.

With Fang Yuan personally leading, access is not a problem.

"Let's go up to the ninth floor first."

Fang Yuan said bluntly.

Take the two of them up on the manual elevator.

"What's it called?"

"It's so easy to go up?"

Sun Simiao took the manual elevator for the first time and was immediately shocked.

"It's a manual elevator."

"Combined with the Mo family's mechanism technique."

"I'm working on a new technology, and I don't even have to move my hands when I succeed."

Fang Yuan explained.

"Awesome, awesome!"

"I didn't expect it to be like this."

Sun Simiao sighed.

The ten-story stargazing tower had already made him sigh how could the floor be built so high.

Now that there is this kind of manual elevator, Sun Simiao once again feels that the Mojia Research Institute is extraordinary.

It didn't take long for Fang Yuan and the three of them to stay on the ninth floor.

The ninth floor is the most mysterious place of the Mojia Research Institute.

When the elevator stops, you need another key to get in and out.

The elevator doors opened, and there were two more security guards guarding the door.

"This layer is the secret of the Mojia Research Institute."

"The most secret things at the moment are studied here first."

Fang Yuan explained.

Drafts of various principles and so on are mainly stored here.

There are also some initial prototypes of the technology that started to take the first step here.

"Fang Yuan, why are you here?"

The giant received the report and walked over.

"Bring Dr. Sun over to have a look."

Fang Yuan explained to the giant.

The giant has been at the Mojia Research Institute these days and has not returned home.

So he hadn't seen Sun Simiao yet, he just knew that there was this guest in the Fang Mansion.

"You are the medicine king Sun Simiao?"

The giant's eyes widened suddenly.

Their generation has all heard of Sun Simiao, the king of medicine.

"It's me."

Sun Simiao smiled.

He was used to being amazed.

So I didn't care much about the surprise of the giant.

"It's hard to imagine that I met a real person."

The giant said excitedly.

"There will be a chance to meet each other in the future."

"Giant, lead the way to introduce our technology to Dr. Sun."

"Whether I can leave Dr. Sun in our Mojia Research Institute will depend on this time."

Fang Yuan said solemnly.

That being said, Fang Yuan had a lot of confidence in the Mojia Research Institute.

There are a lot of things here, they are epoch-making ideas, and many of them were put forward by Fang Yuan.

Some of them already have models, and some are still being studied, but the vitality of the Mohist Research Institute is unique in the world.

"Okay, okay, please come with me!"

The giant was stunned for a moment, and then said excitedly.

He walked in front and briefly introduced to Sun Simiao the ten-story structure of the Mojia Research Institute.

It didn't take long for the giant to lead everyone to a huge machine, the size of several people.

In front of the machine, there were a few people in white coats, who were studying with banknotes, and they just nodded when they saw Fang Yuan and a few people coming.

"It's all iron?"

"Why is it so smooth and shiny?"

Sun Simiao was shocked again when he saw the machine.

The material looks very similar to his "scalpels".

But he remembered that his batch of "scalpels" were all made of special meteorites, which were rare in the outside world.

Now not only rare, but also a huge block in front of their eyes.

"It's called a steam engine, and we're made of steel."

"Steel is actually a type of pig iron, but we purified the carbon in it."

"I don't really understand what carbon is now, the principle is what Fang Yuan said."

Juzi explained.

As he spoke, he patted the steam engine vigorously.

It just sounded, and the sound was crisp and good.

"Steel."

"What's the use of this thing?"

Sun Simiao muttered.

He was shocked, his hands trembling slightly as he stroked the steam engine.

In terms of material, this feeling is very similar to my own "scalpel".

I didn't expect that I thought that the little things in the world could be made by myself here at the Mojia Research Institute.

"According to Fang Yuan's meaning, if it succeeds, it can work instead of people."

The giant's expression became solemn.

He commanded several people present to make a fire and pour water.

As the water boiled, the machine in the middle was pushed slowly, and two pieces of steel were moving back and forth at the other end of the neat end.

The giant dismantled the steel plate on one side of the steam engine, revealing the tight instruments inside.

"If we burn a fire and add water, the water vapor will push the machines inside."

"When the machine moves, the force eventually acts on these two steels, which can be used to propel objects."

"But now I don't know which link has not been done well, our strength is very small, it cannot be regarded as a success, and we need to continue to study."

"If it succeeds, we can replace these two pieces of steel, replace them with something else, put two wheels, maybe it can replace the carriage and so on."

The giant seems to exude a scientific spirit.

When he mentions the steam engine, his eyes are glowing.

For research, Juzi is a natural liking and is willing to contribute his life to scientific research.

"How can you do this?!"

Sun Simiao couldn't believe it.

But he believed in Fang Yuan, and he could see that this thing called the steam engine really had that function.

So what the giant said should be true, there will really be such a magical thing.

"This is a half-layer product, but it has poured the efforts of everyone in our Mojia Research Institute."

"I'll take you to see the firebolt, and it can be said to be a success."

The giant walked to the side.
