Senior brother, stop it, you are the villain!

Three days later.

A golden sword flew through the air, and on top of the sword, a man was hugging a girl tightly. The man is handsome and handsome, and his bearing is extraordinary; the girl, although still young, cannot conceal the beauty of the country.

These two people are Feng Shao and Lin Xiaoran.

After discussing with Deng Jingyun, Feng Shao and Lin Xiaoran left Qingdi City. The two of them didn't take a spiritual boat along the way, they just rode on Feng Shao's Golden Crow Sword and wielded the sword all the way. Three days later, they arrived at the small village they had visited before.

At this time, downstream of the small village, several wooden houses and tents had been erected scatteredly, and simple buildings were under construction. In this camp, all the people walking around were Jiuyou Holy Land disciples dressed in black. Under the leadership of Zuo Linglan, they have been here for more than ten days and are quickly adapting to their new life.

When Feng Shao and Lin Xiaoran came here, the disciples of Jiuyou Holy Land noticed it. They quickly reported to Zuo Linglan, who then received the two of them in the largest wooden house.

Looking at the beautiful pair in front of him, a trace of envy flashed in Zuo Linglan's eyes. But she immediately covered up her envious look and smiled at the two of them: "You two are finally here. We have been waiting for you for a long time."

Before Feng Shao could reply, Lin Xiaoran couldn't wait to say to Zuo Linglan: "Sister Zuo, since you're here, you won't leave in the future, right? My husband wants to build his own foundation, and he doesn't have many people. I hope You can stay and help!"

Zuo Linglan smiled and said: "This is natural. We are very grateful that Mr. Feng is willing to take us in. If there is anyone who can help, I hope you two will not be polite."

Feng Shao smiled and said: "Since Miss Zuo has made a decision, I welcome you. Then, let me tell Miss Zuo about the situation of this land first!"

Zuo Linglan nodded solemnly: "Please tell me."

Afterwards, Feng Shao introduced the land to Zuo Linglan in detail.

This land was called Wulingyuan in ancient times and was once a place rich in spiritual energy. About ten thousand years ago, the spiritual energy here gradually dried up, and the sect that was originally located here was forced to move.

In fact, the reason why this place was originally rich in spiritual energy was due to the natural spiritual energy veins buried deep underground. This vein continuously leaks natural spiritual energy to the surface through a very small branch. Since not much spiritual energy leaked out, after being diluted by the air, it became spiritual energy suitable for monks to use. The sect located here has also become a powerful sect well-known far and near.

However, later, due to geological changes, this small branch was blocked by rock formations, preventing the spiritual energy from leaking to the surface. This situation was mistakenly thought to be the exhaustion of spiritual energy at the time, so the sect moved away without detailed investigation, and the place gradually became deserted.

After tens of thousands of years of changes, the remains of the sect have completely disappeared, leaving only a small, deserted plain.

After listening to Feng Shao's introduction, Zuo Linglan couldn't help but asked in surprise: "Master Feng is indeed knowledgeable and knowledgeable, but how did Master Feng learn about this ancient secret?"

Feng Shao smiled faintly and said, "I was fortunate enough to obtain a geographical map from ancient times, and I only found out about this matter."

Zuo Linglan nodded: "So what Mr. Feng means is that as long as we find a way to open up the underground mineral vein, then we can shape this land into a spiritually abundant place suitable for cultivation?"

"good."

"So Mr. Feng wants to create a sect?"

"No." Feng Shao shook his head, "I plan to create a city here."

Next, Feng Shao told Zuo Linglan his next plan.

"Miss Zuo, in a few days, the spiritual energy pipeline I ordered from Yunjian Pavilion will be delivered. At that time, we can start mining underground natural spiritual energy. However, this natural spiritual energy is too rich. If the monks use it without dilution, If it is absorbed under certain conditions, it will be harmful to the body, so after mining, I have to do some research to find out the optimal dilution ratio before releasing it," Feng Shao said.

Zuo Linglan smiled and said: "In that case, the little girl will join the junior brothers and sisters to wait for Mr. Feng's instructions!"

Two days later, Xue Li, the master of the Yunjian Pavilion Fire Refining Hall, came to Wulingyuan with his former Taiwei Sect disciples. As soon as he saw Feng Shao, Xue Li laughed "haha" and said: "Uncle, I, old Xue Ke, have made all the pipes you want for you! Come over quickly and take a look to see how our old Xue's craftsmanship is. !”

Feng Shao smiled and said: "Hall Master Xue's craftsmanship is beyond praise. Hurry and show it to me, I can't wait!"

Since Feng Shao needed to build at least five hundred meters of spiritual energy pipes, Xue Li created many pipes, and it took several storage rings to install them all. The two found an open space, and Xue Li began to empty the spiritual energy pipes from the storage ring.

The modified spiritual energy pipes adopt a nested design. Each pipe is nearly ten meters long, and there are about sixty pipes in total. There is a pressure relief design on the pipeline, which can relieve the pressure of the spiritual energy layer by layer. In order to express the pressure relief intuitively, Xue Li also designed a pressure gauge very thoughtfully, which made Feng Shao stunned.

Who said the ancients were stupid? People just lack some knowledge due to the limitations of the times. But as long as you give them a chance, they can design something that will surprise you.

The pressure gauge designed by Xue Li is a little rough, but it is original. At least for this world that has never had a pressure gauge, Xue Li's design is already extremely advanced. After some debugging, Feng Shao couldn't help but give Xue Li a thumbs up and praised: "Hall Master Xue, you really are the one who can make such good things!"

Xue Li smiled triumphantly and said: "Uncle, if you look down on anyone, you can't look down on me! Old Xue's craftsmanship could scare even the master of the pavilion back then!"

The two looked at each other and laughed.

Now that all the equipment is available, the next step is to consider drilling.

The diameter of the spiritual energy pipe is one meter, so the width of the drill hole must also be one meter. Feng Shao had no experience in mining. His original plan was to take it step by step and modify the next action according to the situation. But Xue Li slapped his chest and said, "Leave this kind of matter to me, old Xue! It's just drilling a hole, how difficult can it be?"

Feng Shao said quickly: "Hall Master Xue, this matter cannot be taken carelessly. If the spiritual energy leaks accidentally, the consequences will be disastrous!"

Xue Li squatted down, picked up a branch, and drew on the ground while saying: "Uncle, your plan is nothing more than to drill a hole that can go straight to the ground one mile deep. The principle should be similar to digging a well. But The deeper the well is dug, the harder it is to dig below. Generally speaking, a well can reach the sky when it is dug about ten feet, but the hole you have to dig is ten times that deep, so we have to change our thinking. dig."

Xue Li was drawing while talking: "Look, the ground below these ten feet is basically rock, and it cannot be dug with ordinary means. But we are monks, and we have our own means. I The idea is to make a drill bit first, but leave some holes in the drill bit so that the gravel can be transported out through the holes. But if you want to control the drill bit, I'm afraid you have to wait. I'll be able to make this drill for you in two days!"

Feng Shao looked at the drill pattern drawn by Xue Li, and the corner of his mouth twitched.

Isn’t this a simple drill version of the shield machine? Although the form is much simpler than a real shield machine, the principle is the same. It's probably impossible to dig a subway tunnel with the drill bit designed by Xue Li, but it's really not that difficult to drill a 500-meter-deep hole!

Feng Shao couldn't help but fall into deep self-doubt. Although he never dared to look down on the natives of this world, having experienced high-tech life in this world, he always had a sense of superiority in his mentality and felt that he had some knowledge that people in this world did not understand at all. But now, he realizes that his only advantage may be his own knowledge. But when it comes to professional ability, it is completely inferior to the indigenous residents who really study hard.

It seems that I have to correct my mentality. I can't underestimate the people in this world!

After another discussion, the two finally determined the style and usage of the drill bit. It has to be said that some of the monk's methods are much easier than conventional methods. It took several years to actually study a shield machine. Countless researchers forgot to eat and sleep, and then they made a shield machine that is well-known at home and abroad. Looking at them again, it was just a simple sketch that determined the prototype of the magic weapon-like shield machine.

After this magic weapon is made, it will have the ability to store chopped rocks. The saw teeth are reinforced with special materials, and a magic circle is used to add sharp properties, making it easier to chop rocks. This magic weapon can be embedded with spiritual stones to maintain its operation. As for control, any monk at the Golden Core Realm can easily control it, and the threshold is extremely low.

However, after the design was completed, Xue Li sighed with emotion: "Although this kind of tool-like magic weapon has been designed before, they can more or less be used as weapons. The worst ones can also be used to hit people. Do it. This is really the first time for me, Old Xue, to use a magic weapon specially used to drill into the ground!"

Hearing this, Feng Shao nodded thoughtfully: "Perhaps we will make more magical weapons of this type in the future."

Feng Shao almost understood why this world, despite having so many convenient conditions, still failed to develop cultivation technology. Perhaps the monks paid too much attention to the means of killing and ignored the role of tools!
