Let's start by analyzing the sun

Water Tower Top.

Cheng Han had already taken off his waterproof fish-killing suit, put down his bloody fish-killing knife, and changed back into his original black mystic robe.

“Huff~”

The cold wind howled from the top of the tower, fluttering the hem of his black robe.

Hall Master Mystic Lan Jiayao stared at this scene, her beautiful eyes momentarily dazed.

The female mystic was still a little incredulous in her heart that these two completely different images would overlap on the same person.

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

Originally, she planned to directly discuss the promotion of the “poison spore insecticide” method, but the series of experiences just now made her suddenly change her mind.

The other party was by no means an ordinary mystic, and it was 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, looking down at the crowd below, and said again: “Even now, I don’t think I am any different from them.”

Lan Jiayao felt even stranger, how could there be no difference between a mystic and an ordinary person?

It's just that she didn't refute it.

This Hall Master wanted to chat about her experiences as an ordinary person, but more than a hundred years of long time diluted her memory, and she couldn't remember much.

The female mystic decisively changed the topic: “Special Envoy Cheng, you moved to Lanbo Lake, you should have other intentions, right?”

This was a guess.

She had seen strange things such as railing carvings and water tower fishing, and began to think that the other party was a thoughtful person, and his actions were probably meaningful.

Sure enough!

Cheng Han nodded: “Of course!”

He directly stated his plan: “Lanbo Lake is a good place to build ships.”

This answer greatly exceeded Lan Jiayao's expectations.

She asked a little surprised: “What do you want to build ships for? Lanbo Lake is only so big, even if there are ships, they can’t be used.”

Cheng Han's next sentence shocked the female mystic severely.

“The ships I want to build are certainly not for use in Lanbo Lake. We are fighting a war with another world. I heard that it is a water world over there.”

Another world is naturally the Youmiao Realm.

Lan Jiayao was so shocked that her voice was a little distorted: “Special Envoy Cheng, do you want to build ships for another world?”

Cheng Han suddenly changed the topic: “It is said that the warriors and civilians who go to that world all live on the surface of a giant plant called 'Tianye Lotus'.”

The female mystic nodded: “That’s true.”

The so-called “Tianye Lotus” is a super plant shaped like a water lily, with a diameter of more than fifty kilometers, floating on the water like an island.

Cheng Han talked eloquently: “Transportation between different Tianye Lotus mainly relies on large and small 'driftwood boats', but they are often frantically gnawed by large groups of underwater creatures.

“I also heard that the damage rate of driftwood boats is quite astonishing. I don’t know how many warriors and civilians have lost their lives in vain because of this.”

Lan Jiayao was silent for a moment before saying: “The situation will greatly improve after the development period.”

Cheng Han then got to the point: “When building the stone tower yesterday, I researched a method of building ships with stone. They should be more resistant to the gnawing of underwater creatures than driftwood boats.”

In this world, humans live on the spiritual leaves of the sacred banyan tree. Due to environmental restrictions, shipbuilding technology is really terribly weak.

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

The female mystic asked blankly: “How can stones be used to build ships? Won’t they sink?”

Cheng Han shook his head and laughed: “Of course not! As long as you use mystic techniques to do some special treatment, it can float steadily on the water.”

As he spoke, he made a void grab at the ground.

“Crack!”

There was only a soft sound.

A huge stone bar as long as five meters, that is, the giant brick for building the water tower, suddenly floated up and hung in front of the two.

Lan Jiayao watched this scene without speaking.

Cheng Han smiled: “This stone has been treated.”

With a move of his right hand, the stone bar immediately flew out, quickly fell into the water tower, and heavily hit the water surface.

“哗啦!”

Large water waves splashed up.

Next second.

Because the large stone bar floated up and down with the 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 mystic immediately checked it with secret techniques, 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: “That’s right!”

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

In another time and space, it is quite difficult to get such an effect, but in this world, mystic techniques can easily do it.

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

“The science-magic internal combustion engine used for poison spore insecticide is actually an excellent power for driving ships. As long as it is equipped with a propeller, it can propel the stone boat forward.”

The above is the specific shipbuilding plan.

Another important purpose is to find more application occasions for the science-magic internal combustion engine, so that the senior leaders can see the specific role of this thing.

The so-called “transformation” relies on one change after another, eventually forming a huge trend, and ultimately completely changing everything.

Lan Jiayao pondered for a few seconds and said very seriously: “Special Envoy Cheng, your plan is very worth trying.”

The “very worth” in this sentence means that this Hall Master Mystic is tempted.

There is no other reason.

If the stone boat is really proven to be of great use, this will definitely be a huge achievement.

And who doesn't like credit?

Cheng Han laughed and directly made a request: “I need more craftsmen.”

He paused and added: “The more the better.”

Lan Jiayao gave a promise: “I will do my best to solve this matter.”

At the same time.

The female mystic's heart was filled with emotion.

Everyone else thought that Special Envoy Cheng was messing around here, who knew that he was quietly playing a big game.

Lan Jiayao took the opportunity to state her intention: “The method of poison spore insecticide is very clever. Xuan Palace hopes to promote it to the subordinate small spiritual realms. This is also the responsibility of Tianrong Hall.”

Cheng Han immediately returned a promise: “I will do my best to cooperate.”

For him, this was just a small matter.

Isn't it just manufacturing hundreds or thousands of science-magic internal combustion engines, and then letting the Spirit Oak Demon produce a large number of poison spore balls?

It's very simple.

With the increased demand for internal combustion engines, taking advantage of this opportunity, we can also promote industrialized assembly line manufacturing and accumulate relevant experience.

In short.

This is a good thing.

*

Half an hour later.

Lan Jiayao hurried into Jinshan Palace.

The stone boat plan was no small matter. If it was successfully verified, not only Tianrong Hall, but even the entire Xuan Palace would benefit greatly.

Therefore.

It is necessary to report to the Palace Master.

Soon.

The female mystic saw Palace Master Yun Changtian again and reported the matter in detail.

After speaking, Lan Jiayao couldn't help but add: “Palace Master, this matter may be a considerable opportunity for Xuan Palace.”

Palace Master Yun naturally understood the benefits and said decisively: “You and Cheng Han can do this with confidence. 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 managed by Cheng Han.”

Thus.

Without the knowledge of a certain special envoy, he had another large territory under his name.

Lan Jiayao responded excitedly: “Understood!”

At this moment.

The female mystic felt from the bottom of her heart that taking over the position of Hall Master of Tianrong Hall was the wisest decision she had ever made.

None other!
