A disc-shaped magic weapon gradually took shape in the hands of the Taoist Duobao. Some of the design concepts were also referenced to Wu Yan's opinions.

If you only look at the front, this disc-shaped magic weapon is very similar to a shield machine. The shield machine is a tunnel boring machine that uses the shield method. In short, when digging a tunnel, it supports the surrounding rock through the shield shell and pipe sheet to prevent collapse into the tunnel.

The real shield machine is in the shape of a cylinder, while the magic weapon created by Daoist Duobao is in a disc state.

The diameter is only one meter and the thickness is thirty centimeters.

The whole body is golden, and this color was also chosen by Wu Yan. His Nine Yang divine power is golden. The true form of the Immortal Body of the Nine Yang Emperor Sword is also golden, so he likes gold very much.

In addition to the structure of the front like a shield machine, the back of the disc is smooth and complete, and the side is the same, without any gaps.

If it were modern people, I would never imagine that this thing was used to dig tunnels because the design was very unreasonable. Without a shield shell, it could not be supported with pipe sheets, and there was no channel for excavated soil gravel.

But this is a mythical world, and this thing is actually a magic weapon.

"Although I am very confident in refining weapons, I'd better give it a try first."

The Taoist Master Duobao became modest, and Wu Yan was also curious about the effect of this magic weapon. He watched the refining of the Taoist Master Duobao throughout the process. With his current realm and strength, he could not understand it in some places, which could already explain the Taoist Master Duobao's level.

"Then try it."

The Taoist Duobao called a piece of auspicious clouds and flew out of the palace with Wu Yan. The destination was a plain area outside Chaoge City.

However, Wu Yan's attendants, Shang Rong Bi Gan Huang Feihu and others were not qualified to climb the Xiangyun, and could only look up in the palace and look up at King Zhou who flew into the sky.

In the past period, Wu Yan also learned some common sense in this world, that is, the magic of immortals and demons cannot be easily applied to mortals, including the behavior of flying with mortals, which is also contaminated with cause and effect.

Perhaps there will be differences in the future of immortals and mortals, which will start from this period.

But Wu Yan is no longer a mortal. He has practiced the Nine-Turn Yuan Gong to a level of transformation, which can be described as extraordinary.

As for a person with the quasi-saint power of Taoist Duobao, he does not need to worry too much about being involved in cause and effect. After all, he did not directly accept Wu Yan as his disciple, nor did he directly help Wu Yan in war.

Furthermore, the cause and effect of Taoist Duobao has been involved with Wu Yan.

If the great catastrophe of the Gods still happened, then the Taoist Duobao would have to take the Jie Sect’s disciples to stand on the side of Shang Dynasty.

Xiangyun flew very quickly and in a flash, he had already arrived at his destination outside the city.

The Holy Mother of Golden Spirit, the Holy Mother of Turtle Spirit, the Dark Cloud Immortal, and several other disciples of the Jie Sect also followed.

They were also very curious about this new magic weapon developed by Taoist Duobao.

The new term was also invented and created by Wu Yan, and everyone is no longer surprised.

"That's it."

The auspicious clouds landed and then dissipated. The Taoist Duobao and Wu Yan both stepped on the earth. The disc-shaped magic weapon that had been floating beside the Taoist Duobao flew to the ground under the envoy of the Taoist Duobao.

When the collision was about to occur, a thin and unseen light flashed across the disc, and it penetrated directly, as if the earth did not exist at all.

This is the magic of the Daobao who solidified the magic of the ground-shaking technique on this disc-shaped magic weapon.

It is the kind of magic that Tu Xingsun Hui.

When he crawled about ten meters underground, Taoist Duobao said, "Don't worry, you will let the king take a look after our experiments. Or, when the king practices the Nine-Turn Yuangong to the fifth turn, he can condense the three souls and seven spirits into the soul, which can not only leave the body, but also travel to the three realms."

Whether it was the Taoist Duobao or the Holy Mother of the Golden Spirit next to him, they didn't expect that Wu Yan could actually see it clearly.

He really does not have the superpower of perspective, and he dare not easily let his soul power leave his body by being around a quasi-saint like Taoist Duobao.

But there is no need to worry about being discovered by activating the power of Ziwei Emperor Xin. At this distance, Ziwei Emperor Xin can see through clearly.

"I'm not in a hurry, the effect is the most important."

Wu Yan was embarrassed to stare at the underground after being told by Taoist Duobao.

And as he looked away, the disc-shaped magic weapon had already shown itself underground, or it was the effect of removing the ground tracing.

A disc-shaped space with a diameter of one meter was supported. Not only that, under the divine mind of Taoist Duobao, the diameter of the disc began to increase, just like Sun Wukong's Ruyi Golden Cudgel, the size was actually as big as you want.

For the Taoist Duobao, such a skill for refining is too simple.

However, after all, it is a magic weapon refined to open the tunnel, so the changes in size and refinement are also limiting, which is related to the lack of good materials and refining techniques.

The disk with a diameter of three meters began to rotate, and the soil and stones that were touched instantly shattered and were sucked into the disk.

The thickness before was only thirty centimeters, and the thickness now has increased three times as the diameter increases.

But just between breathing, the distance between the disk was already more than three meters, and all the soil and stones along the way were swallowed into it.

Judging from the soil and the volume of stones at a distance of three meters, it should have been full of the space inside the disc, but not only did the disc not be burst, the speed of travel did not slow down at all.

What satisfied Wu Yan even more was that during the process of digging the tunnel of the disc, the soil at the edge did not collapse, because a spell was also solidified on the disc - solidification technique.

Soil, stones, sand and other substances to prevent the tunnel from collapse during the excavation process.

Compared with the technology creation shield machine, the effect of this thing is simply too advanced.

Not to mention anything else, it looks like it does not require energy supply at all, and the mana of Duobao Taoist himself is used during the process.

Judging from the strength of the quasi-saint level of the Taoist Taoist Duobao and the time he has practiced for countless tens of thousands of years, he can even control this disc-shaped magic weapon, which penetrates from one end of the earth to the other end of the earth.

But this time it was just an experiment, so there was no need to drill too long tunnels.

"I have to say that this drill bit structure is really easy to use. It is more efficient than I had expected to imitate pangolins and use bite-blocking to dig tunnels?"

When the Taoist Duobao spoke, he gradually began to use some new words.

At this time, if modern time travelers come and come into contact with Taoist Duobao, or the Holy Mother of the Golden Spirit, the Holy Mother of the Turtle Spirit, they will definitely feel that they have also come through time, at least some of the words they use when speaking are like this.

"I can't see it." Wu Yan pretended to be stupid: "But Brother Dao thinks it's easy to use, it should be easy to use."

The Taoist Duobao smiled, reached out and the disc-shaped magic weapon flew up directly.

Unlike before, when flying up, the disc-shaped magic weapon did not use the ground escape technique, but directly drilled through the ground from the ground.

A three-meter-diameter cave appeared fifty meters away from where Wu Yan and others were.

In such a short time, a length of fifty meters has been dug. If you put it in modern society, as long as you have this magic weapon, you can easily become the richest man in the world.

There will be no market for tunnel boring machines such as shield machines.

It is also very helpful for transportation. It will not lead to long-term closures due to the construction of subways and other facilities. The economic losses in it are also a considerable asset.

"please."

The Taoist Duobao stretched out his hand and signaled Wu Yan to walk in front.

Wu Yan is not polite either. He is King Zhou after all.

Because of the Nine-Turn Yuan Gong, Wu Yan also said that he had reached the level of one-Turn, so the physical fitness he showed in the past few days was also stronger than before, and others didn't find it strange.

After a few big steps, Wu Yan reached fifty meters away and without hesitation, he jumped directly into the ten-meter-deep cave.

Not to mention practicing the Nine-Turn Yuangong, even if he did not practice, ten meters are not high due to King Zhou's original physical fitness.

When Wu Yan jumped down, the Holy Mother of Jin Ling cast a small spell very sensible, and a white ball emitting gentle light appeared beside Wu Yan and fell underground with Wu Yan.

In sight, there is a channel that is fifty meters long and three meters in diameter.

The edges of the passage are like sealed with cement or even concrete, and are more like a whole stone.

This is the magic of curing.

When the light ball made by the Holy Mother of the Golden Spirit fell to the ground, it emitted a ray of light, filling the entire underground passage.

It looks extremely bright, as if it is under the sun on the ground.

When Wu Yan took a few steps forward, Taoist Duobao and others flew down and followed Wu Yan to tour.

Fifty meters are not long. In fact, everyone can see the bottom at a glance, but they still walked through the fifty meters distance with interest.

"It's very good, much better than I thought."

Wu Yan knocked on the stone wall on the edge and stepped on it a little harder. He found that it was solidified very well and there was no need to worry about natural collapse at all.

Of course, if a geological disaster occurs, it may collapse.

However, whether it is Chaoge City or Xinchaoge City's location, this issue has been considered.

In this mythical world, it is easy to calculate such natural disasters.

Furthermore, this is not a world with earth structure. The earth is integrated and only one continent is there, so there is no plate movement.

Unless the powerful starts war and the aftermath causes disasters such as earthquakes, it is inevitable.

"It needs to be reinforced. According to our previous plan, after all, this is a millennium plan."

Taoist Duobao is full of ambitions.

Although this magic weapon is not very eye-catching and of no use in essence, it proves that some of the ideas Wu Yan mentioned can be realized.

"Then I'll trouble you brother Dao, and you all from Jie Sect... fellow disciples."

Wu Yan brought the relationship between the two parties closer, and Taoist Duobao, Holy Mother Jinling and others did not correct his statement.

After all, he obtained the practice method from Taoist Duobao and was also bound to the Jie Sect. When he abdicated in the future, he would inevitably join the Jie Sect.

It is reasonable to say that everyone is a fellow student.

"It should be, it should be."

Everyone agreed.
