Leader Tongtian put down the mobile phone in his hand.

A smile emerged from the corner of his mouth.

"This Xu Ji... I would say he is brave... but he tells me everything..."

"I would say he is timid..."

"All the people can do such a thing as He Bo!"

"Interesting! Interesting!" the saint commented.

It's really interesting, isn't it?

But the leader of Tongtian doesn’t want to interfere!

Everything is Xu Ji's free will.

Let nature take its course, and nature will take its course.

Doing it forcefully is not beautiful!

On this issue, Master Tongtian and Taishang have the same view.

For mortals, excessive interference is harmful to them.

Mortals have their own free will and can make choices.

It doesn't matter if I'm wrong.

The mistakes of this generation will become lessons for the next generation.

From this, it is endless and endless.

Although it is said that Xu Ji is in the lower realm with the saint body and magic power of the Tongtian leader.

But doesn’t Heavenly Dao have any objections?

Then he walked to the bed, picked up the "Historical Records" that he had not finished yesterday, and continued reading.

The Spring and Autumn Period and the Warring States Period, Iron Horse Glacier, come to mind from the words.

……………………

July in Shashuihe is full of vitality.

There are more and more new waterwheels on both sides of the river embankment.

It is updated almost every three days on the river bank.

Last year's old waterwheels have been phased out.

But after it was eliminated, it was not wasted.

People can reuse parts of old waterwheels and use them in new waterwheels.

Other scraps are not wasted.

Or as fuel, or as spare parts for repairing equipment.

In an era of extremely low productivity, even in a mythical world, one must be diligent and thrifty and make effective use of all resources.

On this day, Xu Ji just finished his three-day lecture.

Then a homework was assigned to the children.

Um……

It's the famous chicken and rabbit problem.

Then he got up, rode on the buffalo, and came to the pond that Meng Bai had built in the valley near Taojia Village.

Xu Ji looked at the pieces of bark soaking in the dug ponds.

Then he asked Meng Bai who was here: "Isn't it still possible?"

Meng Bai bowed deeply and apologized: "Tianzun, my disciple is stupid and failed to fulfill Tianzun's instructions. I am guilty! I am guilty!"

"I beg the Heavenly Lord to punish me!"

Xu Ji looked at the bark soaked in the pool water.

They have been soaking for more than half a month.

But it's still the same as it was.

It did not become soft as the information he found on the Internet said.

If the bark cannot be softened by soaking, how can it be pulped?

How to make paper if you can't make pulp?

Could it be...

Is it because the bark of trees in this mythical world is particularly hard?

While building the waterwheel, Xu Ji discovered that in this mythical world, trees grew extremely tall.

Giant trees in deep mountains are usually tens of meters high.

It takes four or five people to hug the tree trunk.

The bark of the tree is as hard as iron, and it is naturally impossible for the people of Shashui today to have such things as iron tools and steel axes.

They only have a few bronze vessels in their hands.

In this way, hundreds of villages on both sides of Shashui River were searched, as well as the surrounding mountains and plains with a radius of hundreds of miles.

Only a few thousand pieces were collected.

Only then did Xu Ji realize that in the human world, copper mines are difficult to smelt.

If you don't have Taoist and magical powers, you can smelt it with real fire.

So he could only put incense copper into the crucible.

It takes one ingot of incense copper to smelt dozens of kilograms of bronze.

Forged bronze wares also require a certain proportion of fragrant copper.

To make it take shape!

Otherwise, with mortal strength, it would be impossible to shape the bronze!

And even with a bronze ax cast in this way, it would be difficult to chop down those huge trees.

It takes several people taking turns to cut down, and it takes more than half a month to chop down several axes to cut down a tree.

After Xu Ji learned about this, he taught the people to make bronze saws.

This greatly increased the efficiency of logging and increased the speed of waterwheel manufacturing on both sides of the Shashui River.

nature……

If the bark of the tree is as hard as iron, it may be difficult to soften it with water.

Or I think too simply and am too superstitious about modern technology!

Thinking like this, Xu Ji comforted Meng Bai: "It has nothing to do with you..."

"Maybe I remembered it wrong!"

"Dig another pond tomorrow... put some fragrant copper into the pond and see the effect!..."

"Yes!" Meng Bai immediately received the decree and took people to dig the pond.

Then, divert water from the channel into the pool.

Several ingots of incense copper were put into the pool - nowadays, because He Bo basically does not need such things as incense copper.

As long as Li Shisan has basic incense, he can meet his daily needs of making clouds and rain.

With the Hebo sacrifices and incense in each village, it became more and more prosperous.

Now Li Shisan can even spare some energy to allocate his mana to adjust the flow rate of relevant water bodies according to the needs of each village.

A little faster here, a little slower there.

To He Bo, it was just a matter of magic.

The entire Shashui River is under his control.

Therefore, even if the fragrant copper is condensed at the normal speed.

The people of Shashui River also suddenly had a lot of fragrant copper.

This led to an increase in the number of folk bronzes.

There were even people starting to plow the fields with bronze vessels.

This was almost unimaginable in the past!

Five days later, Xu Ji came here again to inspect.

However……
