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

After having lunch at the Cuixian Building in Changfeng Village, they rested for a while before setting off for the Grand Canal Ditch at the foot of Tianyue Mountain.

Li Shimin vaguely remembers the time when he was recuperating from his injuries in Cuixian Building.

At that time, he happened to be hit by a big stone and injured his head, and was saved by Li Chengfeng using craniotomy.

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

Li Shimin thought to himself, after he abdicated, he must come to Cuixian Tower to live for a while!

The mountains and rivers here are beautiful, the birds are singing and the flowers are fragrant, and it is indeed a suitable place for seclusion!

……

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

The 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.

This is because the width of the Grand Canal is determined by its geographical location.

And because it is a water canal, Li Shimin wants to dig it a little deeper, so that all the water from the south can 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 surrounded by mountains, 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 together.

Two Grand Canals are connected.

In normal times, both Grand Canals can be opened normally if it is a normal season.

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 is flooding, then both Grand Canals can be opened at the same time to share the flow of floods.

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 carry water.

Wouldn't that be the best of both worlds?

This method was actually thought of by Wei Zheng to Li Chengfeng.

Every time Wei Zheng, Du Ruhui and Fang Xuanling encountered a difficult moment in the development of the Tianyue Grand Canal.

Wei Zheng would be cheeky to come to Li Chengfeng for advice and ask Li Chengfeng what they should do next.

Li Chengfeng answered the question like a stream, and within three seconds, he solved the difficult problem of developing the Tianyue Grand Canal.

Wei Zheng has always felt that Li Chengfeng, the eighth prince, is the reincarnation of the heavenly immortals, and was sent to the Tang Dynasty by the Jade Emperor to save the people of the Tang Dynasty from the dire situation.

Therefore, Wei Zheng has always been very concerned about Li Chengfeng's life safety, and he no longer dares to raise a bar with Li Chengfeng.

From the last time Li Chengfeng was besieged by the 100,000 troops of Tubo in the northern city of Suzhou, it can be seen how much Wei Zheng cares about Li Chengfeng.

……

Get out of the carriage and go straight.

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

The Grand Canal just happened to be dug here, and it couldn't be dug up.

Because there is a mountain in front of you, if you want to dig through it, you have to break it!

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

As a result, the workers were unable to start work.

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

On the left side of the Grand Canal, there is a huge stone.

The stone stands like a hill within the Grand Canal.

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

Some people say that it is broken by brute force, and then the pieces are removed piece by piece.

Others said that it was necessary to use human power to pull the huge stone away.

But these two methods are obviously not feasible.

First, because the stone is so hard that people can't smash it open.

Second, this big stone weighs more than 100,000 catties, which is not an object that can be moved by human beings at all.

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

He looked down at the bullet in the sack in his hand.

I suddenly felt that these scams might be a bit insufficient.

"Good fellow, such a big rock?"

Li Chengfeng came to the edge of the riverbed, and several ministers saw the arrival of Li Chengfeng and Li Shimin, and hurriedly bowed respectfully, saying: "The emperor is good, the eighth prince is good!" ”

After a few greetings, Li Shimin also waved his hand slightly, and said: "Ladies and gentlemen, I specially invited my eighth prince, who is now the world's first prodigy, to break through this eye-catching stone!" Feng'er, are you sure? ”

"Sure, sure!"

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

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

All the ministers present looked at Li Chengfeng in surprise.

Cheng Yanjin's eyes widened and said, "Eighth Prince, you, are you sure to get this stone?" Eighth Prince, don't joke with the ministers! Although I don't read much, don't lie to me! ”

"What am I lying to you for?" Li Chengfeng looked at Cheng Yanjin inexplicably.

I only heard Cheng bite the gold and said: "Eighth Prince, I won't tell you anything, the weight of this boulder is at least more than 100,000 catties, this is not an object that one person can move at all!" If you don't believe it, ask Chen Guogong, a group of veterans, how long have we been pondering here, but we haven't been able to move this huge stone by half a minute! ”

After speaking, Cheng Yanjin looked at Hou Junji.

Hou Junji nodded and said, "Yes, Eighth Prince, don't be reckless, this is really not a stone that can be moved by manpower!" ”

At this moment, Hou Junji has been tanned by the sun.

It looks like you've just come back from digging coal in Africa!

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

Li Chengfeng was angry at that time, so he punished Hou Junji and the three ministers and went to dig the Grand Canal for a month.

Now seeing Hou Junji's appearance, it can be seen that he has indeed worked hard to dig the Grand Canal this month.

Otherwise, it is impossible for the skin to be so tanned.

……

Facing everyone's questions, Li Chengfeng smiled and said, "Hehe, you can't move, it doesn't mean that I, Li Chengfeng, have no choice!" ”

With that, Li Chengfeng jumped into the Grand Canal more than two meters deep.

On the edge of this riverbed, there is a wooden board for people to walk down, but Li Chengfeng just didn't go, just to jump down.

This almost scared Li Shimin again.

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

Fortunately, after Li Chengfeng landed, he got up and patted his little hands, and jumped up again, and Li Shimin's heart breathed a heavy sigh of relief.

"Haha, Your Majesty, look at the Eighth Prince, it's really a light effort!"

Wei Zheng said on the side.
