The top of the water tower.

Cheng Han had already taken off his fish-killing waterproof suit, put down his bloody fish-killing knife, and put on the original Xuanshi black robe.

"Whoo~"

The cold wind whistled past the top of the tower, shaking the hem of the black robe.

The Profound Master Lan Jiayao stared at this scene, her beautiful eyes dazed for a very short moment.

The mysterious female master felt a little unbelievable in her heart, that these two completely different images of characters would overlap on the same person.

Lan Jiayao showed a cold smile: "Special Envoy Cheng, you seem to like being with ordinary people?"

Originally, she planned to directly discuss and promote the method of "killing poisonous spores and insects", but a series of experiences just now made her suddenly change her mind.

The other party is definitely not an idle monk, it is best not to use the usual methods.

Cheng Han's expression was a little strange: "A year ago, I was just an ordinary person."

He stood quietly on the edge, overlooking the crowd below, and said: "Even now, I feel no different from them."

Lan Jiayao felt more and more strange, how could there be no difference between Xuanshi and ordinary people?

It's just that she didn't refute.

The master wanted to talk a few words about her experience as an ordinary person, but the long time of more than 100 years had diluted her memory, and she couldn't remember much.

The mysterious female master decisively changed the subject: "Special Envoy Cheng, you probably have other intentions in moving to the Lanbo Lake, right?"

This is speculation.

She has seen weird things like railing carvings, water tower fishing, etc., and she begins to feel that the other party is a thoughtful person, and most of his actions have other meanings.

as predicted!

Cheng Han nodded and said, "Of course!"

He directly stated his plan: "Lanbo Lake is a good place to build boats."

This answer greatly exceeded Lan Jiayao's expectations.

She was a little surprised and asked: "What are you doing building a boat? The area of ??????Lanbo Lake is only so big, even if you have a boat, you can't use it."

Cheng Han's next sentence shocked the female mysterious master severely.

"The boat I want to build is of course not for use in Lake Lanbo. We are fighting a war with another world. I heard that there is a water world over there."

The other world is naturally Youmiao Realm.

Lan Jiayao was so surprised that her voice was distorted: "Special Envoy Cheng, do you want to build a ship for another world?"

Cheng Han suddenly changed the subject: "It is said that the soldiers and civilians who went to that world all lived on the surface of a giant plant called 'Heavenly Leaf Lotus'."

The female mysterious teacher nodded: "Indeed."

The so-called "Heavenly Leaf Lotus" is a super plant shaped like a water lily, with a diameter of more than fifty kilometers, and floating on the water is comparable to an island.

Cheng Han talked eloquently: "The transportation between different Tianyelian mainly relies on large and small 'driftwood boats', but they are often gnawed by large groups of underwater creatures.

"I've also heard that the damage rate of the driftwood boats is astonishing. I don't know how many soldiers and civilians lost their lives in vain."

Lan Jiayao was silent for a moment, and then said: "After the development period, the situation will be greatly improved."

Only then did Cheng Han get to the point: "When I was building the stone tower yesterday, I researched a way to use stone to build boats. They should be more resistant to the bites of underwater creatures than driftwood boats."

In this world, human beings live on the spiritual leaves of the sacred banyan tree. Due to environmental constraints, the shipbuilding technology is pitifully weak.

Some time ago, he heard about all the tragedies on the front line of the war in Xuan Palace, and he had long thought of building ships in his heart.

The female mysterious teacher asked stupidly: "How do you build a ship with stone? Won't it sink?"

Cheng Han shook his head and laughed: "Of course not! As long as some special treatment is done using mysterious methods, it can float steadily on the water."

As he spoke, he made a false scratch towards the ground.

"Crack!"

Only a small sound was heard.

A huge five-meter-long stone strip, which is the huge bricks used to build the water tower, suddenly floated up and floated in front of the two of them.

Lan Jiayao watched this scene without speaking.

Cheng Han smiled and said, "This stone has been processed."

He moved his right hand, and the stone flew out immediately, quickly fell into the water tower, and hit the water surface heavily.

"Whoa!"

A large wave of water splashed up.

next second.

Because the big stone strip fluctuated up and down with the water waves, there was no sign of sinking at all, just like a piece of wood.

Lan Jiayao blurted out: "What's going on?"

The female mysterious master immediately checked it with a secret method, and suddenly realized: "I understand! There are a lot of pores in the stone, and the weight is much lighter than it looks."

Cheng Han smiled and said, "Exactly!"

This stone is lighter than wood, which is actually the principle of foam.

In another time and space, it is quite difficult to achieve such an effect, but in this world, Xuanfa can do it with ease.

Cheng Han pointed at his feet: "Stones are everywhere, and the materials are inexhaustible. The thickness of the hull can be made five or six meters thick or even more, which can effectively resist gnawing.

"The Kemo internal combustion engine used to kill the poisonous spores is actually an excellent power to drive the ship. As long as it is equipped with a propeller, it can push the stone ship forward."

The above is the specific plan for shipbuilding.

Another important purpose is to find more application occasions for the Kemo internal combustion engine, so that the high-level bosses can see the specific role of this thing.

The so-called "reform" is to rely on one after another to change, and finally form a huge wave, and finally completely change everything.

????????????????????????????????????????????????????????????????????????????????????????????????

The "very worth it" in this sentence means that the profound master in charge of the palace is moved.

There is no reason for it.

If stone boats do prove to be useful, it will be a huge credit.

And credit, who doesn't like it?
Cheng Han laughed and asked directly: "I need more craftsmen."

He paused and added: "The more the better."

Lan Jiayao made a promise: "I will try my best to resolve this matter."

at the same time.

The female mysterious teacher's heart was filled with emotion.

Everyone else thought that Special Envoy Cheng was here to fool around, but who knew that he was quietly playing a big game of chess.

Lan Jiayao took advantage of the opportunity to express her intentions: "The method of killing poisonous spores is very clever. Xuangong hopes to promote it to all the small spirit realms under it. This is also the duty of Tianyan Palace."

Cheng Han immediately replied with a promise: "I will try my best to cooperate."

For him, it's just a small thing.

Isn't it just to manufacture hundreds of thousands of Kemo internal combustion engines, and then let the spirit oak demon produce a large number of poisonous spore balls?

Very simple.

The demand for internal combustion engines has increased significantly. Taking advantage of this opportunity, we can also promote industrialized assembly line manufacturing and accumulate relevant experience.

In short.

This is a good thing.

*
After half an hour.

Lan Jiayao hurried into Jinshan Palace.

The plan of the stone boat is not a trivial matter. If the verification is successful, not only the Tianyan Palace, but even the entire Xuan Palace will benefit a lot.

Therefore.

It is necessary to report to the Palace Master.

soon.

The female Xuanshi met the palace lord Yun Changtian again, and reported the matter in detail.

After finishing speaking, Lan Jiayao couldn't help adding: "Palace Master, this matter may be a great opportunity for Xuangong."

Palace Master Yun naturally understood the benefits, and said decisively: "You and Cheng Han let go of this matter, if you have any difficulties, you can come to me at any time!"

Xuan Du thought for a while, and said again: "Huanlan Mountain will be assigned to Tianrong Hall, and Cheng Han will have full jurisdiction."

then.

Without the knowledge of a certain special envoy, he has acquired a considerable territory under his name.

Lan Jiayao responded excitedly: "Understood!"

this moment.

The female mysterious teacher felt from the bottom of her heart that it was the most sensible decision in her life to take over the position of head of the Tianyan Palace.

none of them!
