...

"Master, I want to swim."

"Go to the well in the backyard to get some water, take a shower and feel it."

"Master, I want to go swimming in the river."

"Then just dig a hole in the backyard and pour more water into it!"

"Master..."

"Ogawa!!!"

At the dinner table, Lin Zhengying couldn't stand Xigua Taro's nonsense anymore and roared angrily.

Lin Wangchuan, who was covered in mud, hurried back from the backyard.

"What's wrong, Master?"

"When will the swimming pool be repaired?"

"Cement in the lake/Master! When the cement dries, you and your junior brother can swim in the water!"

"Really? Senior brother!"

"Yes! Junior brother!"

Heard such good news.

Xigua Taro couldn't wait to follow his senior brother, who was known as an encyclopedia, to the backyard to take a look at the swimming pool that was about to take shape!

...

At this moment, behind the temple, a square pond three meters deep, 20 meters long and 10 meters wide has been dug.

In the center of the pool was the cement that Lin Wangchuan had reconciled. Xigua Tarang curiously walked over and pointed at the mud lake and asked, "Is this the cement that Senior Brother mentioned?"

"Yes! This thing is cement!"

Lin Wangchuan said: "Only a swimming pool built with this thing can have higher durability."

"Senior brother is really awesome, he always knows some weird stuff."

"If you read more books, you'll be able to do it naturally."

And the book Lin Wangchuan talked about...

Let’s start with the three essential sacred books for time travel.

The first book "On Staff Assistants - The Art of Serving the Chief".

The title of the book is simple and crude.

The content is similarly unpretentious.

If you cannot rule the world with letters, bring peace with force, and do not know agricultural technology, take this book and travel back to ancient times.

It's the best choice.

This book beats all official and career novels in an instant, and can be called "Sun Tzu's Art of War" in officialdom. Take it back to ancient times, and you will be the best loser of a wealthy family.

It's a pity that Lin Wangchuan doesn't care about it. He doesn't recommend it to Little Watermelon Taro either.

As for the second book "Barefoot Doctor", Lin Wangchuan already has it. And it is the one that is firmly engraved in his mind. So it is this one that Xigua Taro is reading.

After all, no one in this world can live without having a headache or fever.

Especially Watermelon Taro's mother died because of this. Alas, forget it, let's not mention it.

This book records not only medical skills, but also methods of digging wells, digging cesspools, and exterminating snakes, insects, rats, and ants. With this book, Hua Tuo and Zhang Zhongjing had to worship themselves as their teachers.

If there is a way of heaven in this world, then "Barefoot Doctor" can become a treasure of luck. In the words of Honghuang Wen, it is the treasure of acquired merit or the treasure of medicine. In mythology, it is a candidate for Daluo. It is only a matter of time before transcendence in the future.

, the owner of the book can be regarded as a quasi-sage in the world, and can also become a very noble immortal in mythology.

As for the third book...

"Friends of Dual-Use Talents" is divided into two volumes.

It was picked up by Lin Wangchuan Fuyuan after he upgraded and finally reached a high level.

The book lives up to its name.

The first volume governs the army, and the second volume provides peace of mind to the people.

It can be called a must-have book for time travellers.

In the first volume, array training includes battlefield first aid, field survival and team organization, and even the techniques of firing artillery, tanks and aircraft are introduced. The second volume is even more impressive, including soil identification, greenhouse manufacturing, grain reprocessing, water conservancy construction, and basic handicrafts.

etc.

Taking this book back to ancient times, you can prepare in advance even the founding year of the People's Republic of China.

And at this moment...

Lin Wangchuan built the swimming pool, and the cement technology used came from this.

...

Normal industrial cement steps are very troublesome!

Lin Wangchuan explained to Xigua Tarang while adding cement to the edge of the pool:

“The first step is to crush limestone, water, iron ore and other materials together, and then mix them evenly.

The second step is to control the proportion of production raw materials. Generally speaking, cement powder only accounts for about 40%, and other raw materials account for about 60%. The proportions are determined according to the needs of different building structures.

The third step...all in all is very troublesome.

But my senior brother happens to know a simple method of making cement.

That is to grind limestone and clay into flour, and then calcine the clinker. Grind the clinker and the slag left after ironmaking together to make cement. This is a simple method of making cement, commonly known as local method of burning cement."

After hearing Lin Wangchuan's explanation, Xigua Tarang admired this senior brother even more.

I couldn’t help but jump down together and play with and smear cement.

A few days later.

The cement pond is officially completed, and the next step is the process of water diversion.

The nearest river to here is called Xiaolong River.

Xiaolong River is the smallest of the three rivers flowing through Sanhe Town.

The other two are the Dragon King River and the Dragon Mother River.

It just happened to be a family of three.

Lin Wangchuan and Xigua Tarang came to the Xiaolong River a mile away.

The original intention was to dig a small trench from here to divert the river water into the swimming pool.

As a result, this hasn't happened yet.

Hey, hey!

"Why is the river dry?"

Looking at the Xiaolong River, which was flowing fast just a few days ago, why did it suddenly dry up?

The two of them were very puzzled.

Xigua Taro was the first to discover the problem.

"Brother, something must have happened upstream."

Xigua Taro pointed in the direction upstream and said:

"I heard a lot of noise somewhere."

"Let's go and have a look!"

With that said, the two brothers headed upstream.

This is quite a distance of several miles!

Lin Wangchuan was already a little tired.

"How did you hear it from so far away?"

"My ears are working fine."

"I wouldn't even use such a method!"

In the end, the two found the source of the problem ten miles upstream.

Be obedient.

The sound here can be heard even ten miles away.

Could it be that this Watermelon Taro has a good ear?
