Then, Li Shimin laughed and said, "Haha, is the Eighth Prince really smart or fake? Can you think of this kind of attention when setting fire to the mountain? If the fire could burn the entire mountain, I would have done it long ago, would it be his turn?"

"Yes, the emperor, so the old minister doesn't know what the eighth prince wants. The old minister just did it according to the eighth prince's instructions! After all, the approval document for digging the Grand Canal is now in his hands, and he is the main person in charge!" Hou Junji said.

"Um!"

"What the hell is he doing?"

Li Shimin frowned and thought.

Even children know that the flames can only burn down trees on the uphill, but not the entire hillside!

Therefore, the strategy of setting fire to the mountain is simply not feasible.

However, Li Shimin felt that he could not look at Li Chengfeng from an ordinary perspective, so he was willing to wait and see what Li Chengfeng was playing.

...

To Li Shimin's left, there is a river full of water.

The river water is turbid and turns yellow.

Li Shimin vaguely remembered that he was here before, but was hit by the huge rocks rolling down from the mountain.

If Li Chengfeng hadn't performed a craniotomy on himself, he would have died long ago.

Although the condition has improved now, whenever Li Shimin is overworked, he will feel a vague pain in his mind.

It is probably the sequelae left at that time, and it is more cost-effective than death!

"Your Majesty, do you want the old minister to stop the Eighth Prince?"

Hou Junji asked.

Li Shimin shook his head and said, "No need, let him go! We can no longer dig the Grand Canal at the end of June, so it's better to let the Eighth Prince give it a try!"

"Well... the old minister is going to work hard first, and there are still a few cars of firewood that have not been finished!"

"Okay, go and do your business, I'll come here to watch!"

Li Shimin waved his hand and signaled Hou Junji to retreat first.

On the shore on the left, there was a group of people who came to see Li Chengfeng dig the mountain.

Most of these people are rich children from Chang'an City and some literati and strategists.

They heard that the Eighth Prince was going to dig a mountain?

How is this possible? How can it be dug up Tianyue Mountain with manpower?

Isn’t this the act of Yugong moving mountains?

I have to say that Li Chengfeng is really noisy!

A few days ago, the Dragon King sacrificial ceremony had just been destroyed, and now another plan to set fire to the mountain was come up with a group of people to watch.

Li Shimin wanted to see what other tricks he could do?

What if Li Chengfeng could really get rid of this mountain?

I, Li Shimin, picked up these stones and ate them, dipped in sauce, and it was crispy.

People on the side were also talking.

"Starting the mountain? Is this working? The mountain is made of soil and rocks. Burning the mountain can only burn trees. How can it burn the soil?"

"Yes, so we're all confused, what the Eighth Prince is doing?"

"He is known as the strongest genius prodigy in the history of the Tang Dynasty. He is one of the best in terms of wisdom and force! So I think the Eighth Prince must have his own way!"

"Hmph, don't think too much! It's just raining, and the soil on the mountains is wet, and there is rain on the trees, so it can't be burned at all, so this method is simply not feasible!"

"Yes, why can't the Eighth Prince even think of this truth? It's really strange!"

...

In the face of other people's criticism, Li Shimin also heard it.

The mountain is so wet, even if it gets dry firewood, it is useless. Whether the fire can be burned is another matter.

But in fact, Li Chengfeng had long thought of this little difficulty.

Li Chengfeng spent 30,000 naughty points from the system and purchased more than 1,000 barrels of diesel in batches, all of which were placed on the top of the mountain.

Then, Li Chengfeng distributed the diesel to the soldiers and asked the soldiers to fall down along the trees in the gully.

The soldiers followed the instructions one by one.

Everyone was also curious about where Li Chengfeng got so much diesel from.

Li Chengfeng was too lazy to explain, just said that he was transformed by himself. Do you believe it or not?

As a result, the soldiers really believed that Li Chengfeng must be the reincarnation of a god. They were even more loyal to Li Chengfeng!

The ancients were so easy to cheat.

I said that I had a system, but no one believed it, but I believed it all!

Don’t forget that the system is something that is even more awesome than a god!

After getting the firewood and diesel ready, Li Chengfeng began to instruct people to light the fire.

After the fire was burned, Li Chengfeng ordered the Xuanjia Army to watch the flames burn, and then ran down the mountain to sleep.

Because the Xuanjia Army was used to living in the mountains, they took turns to watch the flames.

Soon, a bonfire, like a long red dragon, slowly emerged from the Tianyue Mountains.

Above the mountains, blue smoke rose and flames were beating.

Li Chengfeng instructed that the mountain would be burned for three days and three nights, and the flames could not stop.

As a scientific research genius in the 21st century, Li Chengfeng has also been very knowledgeable about geology.

He observed that the Tianyue Mountains were hard soil and were mixed with many rocks. This method was easier to use thermal expansion and contraction. The mountain expanded, then shrunk, and finally cracked.

If it is soft soil, this method may not be effective!

...

Walking down the mountain range, Li Chengfeng looked back and then walked forward yawning.

He worked hard all night last night and didn't sleep all night. Now he feels sleepy.

Along the way, Li Chengfeng met Li Shimin, and Li Shimin reached out and stopped Li Chengfeng.

Li Shimin said: "Feng'er, aren't you here to dig the Tianyue Mountains? How to burn it with fire? Does it work?"

Li Shimin asked with his own question.

Not only Li Shimin's question, but the ministers and the people on the side were all confused.

Because Li Chengfeng burned the mountain, only burned one gap, not the entire mountain range? No one knows why Li Chengfeng did this!

Li Chengfeng said: "Yes, an interesting physical phenomenon called thermal expansion and contraction. Do you understand father?"

"Heat expansion and contraction? This... haha, I don't understand!" Li Shimin smiled and shook his head.

Li Chengfeng said: "It means that when an object is heated, its volume will expand, and after cooling, its volume will shrink! Then the atomic structure will change, which is probably like this! Well, I'm going back to sleep, ha..."

Li Chengfeng yawned.

But Li Shimin was confused.

Because Li Shimin couldn't understand Li Chengfeng's professional terms at all.

In order not to appear low in IQ, Li Shimin could only nod and praise Li Chengfeng for your awesomeness and know a lot!

"But Feng'er, does your method really work?"

"I don't know, whether it works or not, it will be clear in three days! If it rains and put out the fire, it's hard to say!"

"Goodbye, my father, I'm sleepy, I'll go back to bed first!"

"Okay, then you can have a good rest!"
