Let's start by analyzing the sun

The Head Xuan Master of Tianrong Hall, Lan Jiayao, was feeling a bit of a headache at the moment.

Because she had an official document in front of her.

The signatory of the document was none other than the genius Xuan Shi, Cheng Han, who had single-handedly repaired a section of the Heavenly Ring, which made her take it seriously.

Lan Jiayao picked up the beautifully bound document, skipped the long, meaningless preamble, and went straight to the text at the end:

"...In order to effectively maintain and repair the spirit branches and leaves of the Divine Banyan, this Hall urgently needs thirty artisans and two hundred apprentice craftsmen.

"I hereby apply, please approve!"

Lan Jiayao put down the document, and the cold mist in her beautiful eyes flickered slightly.

What the hell!

What does repairing the Divine Banyan's damage have to do with craftsmen?

Could it be that the craftsmen are supposed to use saws and planes to give the Divine Banyan a beauty makeover?

This Head Xuan Master couldn't help but "humph", and a few illusory ice flowers appeared silently nearby.

Lan Jiayao turned to look at a maid, her tone as indifferent as ever: "How many explosions have occurred in the 'Science and Demon Research Institute' under the jurisdiction of Special Envoy Cheng recently?"

The maid, who was extremely beautiful, immediately replied: "In the last half month, the Science and Demon Research Institute has been intensively testing 'internal combustion engines', resulting in a total of twelve explosions.

"In these experimental accidents, a total of three artisans and twelve apprentices were injured, and the Science and Demon Research Institute is currently quite short of manpower."

This answer clearly revealed the true reason for "requesting" craftsmen.

The "repairing the Divine Banyan" was obviously just a superficial excuse.

Lan Jiayao was silent, and the ice flowers floating around her instantly multiplied several times.

Honestly speaking.

If any other Xuan Shi dared to do this, the Head Xuan Master would definitely reward them with an ice-type Xuan technique without hesitation, letting them experience what it means to be chilled to the bone.

But Special Envoy Cheng was different.

Palace Master had privately instructed her to satisfy Special Envoy Cheng's requests as much as possible.

Lan Jiayao sighed: "I remember that the master craftsman of the Science and Demon Research Institute has a very bad relationship with the Tiangong Hall, right?"

The maid nodded: "Yes! That master craftsman, 'Luo Zhenhuan', had an argument with the Deputy Head of the Tiangong Hall many years ago, and has been marginalized ever since."

Lan Jiayao's tone fluctuated for once: "So this is asking me to come forward and ask the Tiangong Hall for a batch of craftsmen?"

The maid did not speak, but judging from her expression, she obviously agreed with this conclusion.

After all, many people in Xuan Palace knew that Head Lan was the Palace Master's confidante.

If Head Lan personally approached the Tiangong Hall, the other party would most likely agree.

In other words.

The meaning of this official document was to use the Head Xuan Master as a gun.

Lan Jiayao sat quietly for a few seconds, her pretty face full of helplessness: "Clearly possessing outstanding talent, yet spending so much thought on useless things, are all geniuses so willful?"

In the eyes of this female Head, the Science and Demon Research Institute was just a product of nonsense.

But the Palace Master turned a blind eye, so she couldn't say much.

The female Xuan Master slowly stood up, finally compromising: "Forget it, I'll go to the Tiangong Hall!"

Originally, she thought that serving as the Head of the new institution was like lying down and picking up merit, but now it seemed not so easy.

Lan Jiayao walked quickly towards the door, and every step she took, an ice flower bloomed on the ground.

From this small detail, it could be seen that her mood was obviously not as calm as her face.

As a Head Xuan Master, she had to run errands for a Xuan Shi, who was the superior and who was the subordinate?

This is too bullying!

Forest Villa.

What happened in the Tiangong Hall was quickly reported.

Cheng Han smiled contentedly after listening to the servant's report: "Head Lan is indeed capable!"

This female Xuan Master went straight to the Tiangong Hall and demanded sixty artisans and four hundred apprentice craftsmen.

This was not a small number, twice the number requested in the official document.

And the Xuan Master in charge of the Tiangong Hall, of course, refused.

Now that the war between the two worlds has already begun, the front line consumes a huge amount of supplies every day, and the Tiangong Hall has tasks to complete every month.

After some bargaining.

The Tiangong Hall, considering the Palace Master's face, reluctantly agreed to "squeeze out" thirty-five artisans and two hundred and fifty apprentice craftsmen.

This was more than what the Science and Demon Research Institute needed, how could he not be satisfied?

Cheng Han sighed at how "capable Xuan Masters are", and continued to study and analyze the large amount of high-end knowledge obtained from the Source Xuan Crystal.

In the morning, he used this knowledge to complete a Xuan Seal.

"Spiritual Myriad Forest Xuan Seal, Tier 1, Completeness 62.82%."

The completeness increased by 9.15%, the increase was not much, but the upper limit of mental value increased by 1.2 points, reaching another new high of 225.7 points.

Cheng Han pondered for a long time, and sighed: "If I can understand the principle of the Divine Banyan extracting Source Xuan Crystals from the Source Energy Abyss, perhaps condensing a Divine Seal would be no problem."

He shook his head: "It's a pity that the level is too high, I can only analyze a little bit of the surface."

Cheng Han adjusted his mood, took out a stack of manuscript paper, and began to write a letter to the Science and Demon Research Institute, assigning a task.

By the way.

He also wanted to test the new ability derived from the Spiritual Myriad Forest Xuan Seal.

After all, the official document previously submitted to the Head Xuan Master clearly stated that requesting craftsmen was for better maintenance of the Divine Banyan.

This genius speaks, one spit is a pit, how could he deceive a woman?

Three days later.

A large number of parts handmade by artisans were transported to the forest.

A group of Spirit Oak Tree "workers", under the guidance of several apprentices, successfully assembled a large single-cylinder "Science and Demon Internal Combustion Engine".

The reason it was called "Science and Demon Internal Combustion Engine" was because it should have more than a dozen unique technologies from this world.

In this process, they demonstrated skills comparable to a sixth-grade fitter, filing and grinding like crazy, repairing many unqualified parts.

This ultra-high efficiency and extremely exquisite craftsmanship made a group of craftsmen stunned, each with a feeling of "today I know I am not as good as a tree".

Liang Ming, a Class B craftsman, boldly suggested: "Special Envoy Cheng, I heard that this batch of Spirit Oak Trees will be distributed to the small spirit realms below in a few months.

"These Spirit Oak Trees are all comparable to the best apprentices, I think it's best to keep them."

Cheng Han replied with a smile: "Don't worry, they won't go to the small spirit realms, the Palace Master has applied for another batch of Spirit Oak Trees from the Divine City above."

Previously, another purpose of him using the Spirit Oak Trees to repair the Heavenly Ring was to keep these tree spirits.

He had carefully cultivated them for so long, of course, he had to find a way to keep them.

Two more days passed.

Since the establishment of the Tianrong Hall, it performed its duties for the first time.

More than a hundred Scarlet Armor Army warriors spent a lot of effort to transport two Science and Demon Internal Combustion Engines to the underground.

The craftsmen started the machines and connected a pipeline.

This operation lasted for two days and two nights, which was considered a verification of reliability.

*

The next day.

The Head Xuan Master of Tianrong Hall, Lan Jiayao, heard shocking news from the maid.

"Vice Head Cheng used two Science and Demon Internal Combustion Engines to inject a spray called 'Poison Spore Insecticide' into the underground of the Heavenly Ring.

"After the experiment, the Scarlet Armor Army soldiers conducted an inspection wearing masks and found at least three thousand Void Insect corpses."

The female Xuan Master "swished" and stood up, her tone full of astonishment: "Where are the corpses? Get me one!"

The maid immediately obeyed the order and left.

A quarter of an hour later.

Lan Jiayao saw the Void Insect corpse.

The originally green insects were now covered in red sores, and many places were ulcerated and oozing foul-smelling liquid.

The Head Xuan Master quietly looked at it for a long time, her expression extremely subtle.

Originally, she always thought that the Science and Demon Research Institute was just fooling around.

But judging from the miserable state of this insect corpse, her thoughts were completely wrong.

This was clearly something of great use.

More importantly, so many Void Insects were killed, and the Scarlet Armor Army had no casualties.

And it was in the spring, which was not suitable for exterminating insects!

Lan Jiayao waved her hand and ordered: "Take the insect away."

"Yes!"

The subordinate immediately followed the order.

Lan Jiayao watched the insect corpse being dragged away, and murmured in a very low voice: "So this is how you can kill insects, I've really learned something!"

She added in her heart: "Amazing!"

This compliment was naturally aimed at the Special Envoy who came up with this ingenious idea.

At this moment.

The Head Xuan Master no longer had any "bullied" thoughts about being forced to ask for craftsmen before.

Lan Jiayao was in a great mood, turned to look at the maid, and ordered: "Go and find out if the Science and Demon Research Institute is short of manpower and supplies."

"Yes!"

Lan Jiayao waved her hand again, a rare smile on her pretty face: "Prepare the Xuan Boat immediately, I want to report this to the Palace Master immediately!"

"Yes!"
