When Li Chengfeng, Li Shimin and others arrived at the foot of Tianyue Mountain in Changfeng Village, it was already noon.

After they had lunch at the Cuixian Building in Changfeng Village, they rested for a while before planning to set off for the Grand Canal at the foot of Tianyue Mountain.

Li Shimin vaguely remembered the time when he was recuperating in Cuixianlou.

At that time, I happened to be hit by a big rock and injured my head, and was rescued by Li Chengfeng with a craniotomy.

So whenever he thinks of Cuixian Tower, Li Shimin has a general feeling in his heart.

Li Shimin thought to himself, after he abdicates, he must live in Cuixianlou for a while!

There are beautiful mountains and clear waters, singing birds and fragrant flowers. It is indeed a place suitable for seclusion!

…

Soon, Li Shimin, Li Chengfeng and Wei Zheng came to the Grand Canal ditch at the foot of Tianyue Mountain.

This Grand Canal is two meters deep and more than ten meters wide.

The narrow place is about seven or eight meters, but the wide place is twenty meters wide.

Because people determine the width of the Grand Canal based on geographical location.

And because it is the Grand Canal for transporting water, Li Shimin wanted to dig it deeper so that all the water from the south could be transported to the north.

In addition, behind Tianyue Mountain, there is also a Hangzheng Reservoir.

That reservoir was also dug by Li Shimin relying on the terrain.

Where there are mountains on all sides, a large groove in the middle can be used as a reservoir, and then connect the Tianyue Grand Canal and the Beijing-Hangzhou Grand Canal.

The two Grand Canals are connected.

Usually, if it is a normal season, then both Grand Canals can be opened normally.

Or directly close the Tianyue Grand Canal and transport all the water to the Beijing-Hangzhou Grand Canal.

If it coincides with the rainy season and there are floods, the two Grand Canals can be opened at the same time to share the passage of the flood.

If it coincides with the dry season, then the Beijing-Hangzhou Grand Canal can be closed, and then only the Tianyue Grand Canal can be opened to transport water.

In this way, wouldn't it be the best of both worlds?

This method was actually what Wei Zheng asked Li Chengfeng to think about.

Every time Wei Zheng, Du Ruhui, and Fang Xuanling encountered difficulties in developing the Tianyue Grand Canal.

Wei Zheng would have the cheek to come to Li Chengfeng for advice, and ask Li Chengfeng what they should do next.

And Li Chengfeng answered fluently, and within three seconds, he solved the intractable problems of developing the Tianyue Grand Canal.

Wei Zheng always felt that the eighth prince, Li Chengfeng, was the reincarnation of a **** in the sky, sent by the Jade Emperor to the Tang Dynasty to save the people of the Tang Dynasty from suffering.

So Wei Zheng has always cared about Li Chengfeng's life safety, and never dared to argue with Li Chengfeng again.

From the last time when Li Chengfeng was besieged by Tubo's 100,000 troops in the northern city of Suzhou, it was obvious how much Wei Zheng cared about Li Chengfeng.

…

Get out of the carriage and go straight all the way.

Everyone came all the way to the foot of Tianyue Mountain.

The Grand Canal just happened to be dug here, so it couldn't be dug through.

Because there is a mountain ahead, if you want to dig through it, you have to break through the mountain!

Fortunately, the mountain has not yet been broken, and a huge stone rolled down from the mountain and fell into the Grand Canal.

As a result, workers were unable to start work.

At this moment, there are dozens of farmers in the dry and hard riverbed of the Grand Canal, digging the Grand Canal.

And on the left side of the Grand Canal, there is a super huge stone.

This stone stands like a hill in the Grand Canal.

More than a dozen ministers were discussing how to move this stone up from the Grand Canal.

Some people say that they should be broken open with brute force, and then removed piece by piece.

Others said that human power was used to pull this huge stone away.

But these two methods are obviously not feasible.

First, because the rock is so hard that people can't break it.

Second, this big rock weighs more than 100,000 catties. It is not an object that can be moved by human power at all.

And at this moment, Li Chengfeng also frowned slightly when he saw the boulder.

He lowered his head and looked at the fraudulent ammunition in the sack in his hand.

Suddenly, I felt that these fraudulent bombs might not be enough.

"Good guy, such a big stone?"

When Li Chengfeng came to the edge of the riverbed, several ministers saw Li Chengfeng and Li Shimin coming, and quickly bowed respectfully, saying: "Hello, Your Majesty, and Hello, Eighth Prince!"

After a few greetings, Li Shimin also waved his hand slightly, and said: "My dear friends, I have specially invited my eighth prince, who is now the world's number one child prodigy, to break this unsightly stone! Son, are you sure?"

"I'm sure, of course I'm sure!"

The corners of Li Chengfeng's mouth curled up slightly, and he smiled inwardly: "I don't believe it, ten bogus bombs can't blow you up, can't a hundred booby bombs blow you up? Anyway, I, Li Chengfeng, have a lot of bogus bombs!"

When Li Chengfeng said that he had a way to get rid of this big rock.

All the ministers present looked at Li Chengfeng in surprise.

Cheng Yaojin's eyes widened, and said: "Eighth Prince, you, are you sure you can get rid of this stone? Eighth Prince, don't joke with the old minister! Although I don't study much, don't lie to me!"

"What did I lie to you for?" Li Chengfeng looked at Cheng Yaojin because he didn't know.

Just listen to Cheng Yaojin, and said: "Eighth Prince, to tell you the truth, the weight of this boulder is at least over 100,000 jins, it is not an object that can be moved by one person at all! If you don't believe me, just ask Chen Guogong, UU Read the book www.uukanshu.com We, a group of veterans, have been pondering here for a long time, but we have not been able to move this huge stone by half!"

After finishing speaking, Cheng Yaojin looked at Hou Junji.

Hou Junji nodded, and said, "Yes, Eighth Prince, don't be brave, this is really not a rock that can be moved by human power!"

At this moment, Hou Junji is already tanned by the sun.

Looks like he just got back from digging coal in Africa!

Wasn't it because Li Shimin was seriously ill last time, when Li Chengfeng went to court, Hou Junji and three ministers actually went out to play?

When Li Chengfeng got angry, he punished Hou Junji and the three ministers by digging the Grand Canal for a month.

Seeing Hou Junji's behavior now, it can be seen that he has indeed worked harder to dig the Grand Canal this month.

Otherwise, the skin would not be so tanned.

…

Faced with everyone's questions, Li Chengfeng smiled and said, "Hey, if you can't move it, it doesn't mean that I, Li Chengfeng, can't do it!"

After finishing speaking, Li Chengfeng jumped into the Grand Canal which was more than two meters deep.

On the edge of the river bed, there is a wooden plank for people to walk down, but Li Chengfeng refuses to go, just wants to jump off.

This almost scared Li Shimin again.

If Li Chengfeng accidentally fell and injured himself, he would be responsible.

Fortunately, after Li Chengfeng landed, he got up, clapped his little hands, and jumped up vigorously, Li Shimin was relieved deeply.

"Haha, Your Majesty, look at the Eighth Prince, he really has light skills!"

Wei Zheng said something aside.
