Chapter 4169: fortress

"It's empty inside!"

Caiying looked down and shouted.

Sure enough, this is indeed a fortress, it looks like a weakened version of Anding City.

The dark iron is obviously much more valuable than the fire copper.

also had a lot of agencies, but Zhou Shu didn't want to find it out. It was unnecessary. Destructive digging was more convenient.

is not the heavens, so I can’t take it back.

Caiying realized something, "Xian Ting did it, right?"

"Not sure, go down and take a look."

Zhou Shu went down, "There is no one inside, but I can't relax."

The space in the fort is very large and empty, and a formation occupies about 80% of the internal space.

is definitely the formation method. There are tens of thousands of copper pillars engraved with runes that are as high as thousands of feet. Power flows in the middle, and the runes flash from time to time, and they are still working.

The side of the 　　 array is divided into dozens of rooms, and the other side is connected to a pipe with a thickness of tens of miles. Looking at the direction, it should lead to the right half of the fortress.

Caiying waited for a while, "Zhou, what did you see?"

Zhou Shu calmly said, "The material of the copper pillar is Jingming copper, which is a special product of one of the 33 days and tomorrow. It is a very good array material, compatible with almost all formations, not limited to a certain rule, and the city is stable. Just used it, we also used the teleportation array of Xianshu City, and the power core of the array is various magic crystals. There are at least one hundred magic crystals of different sizes under each copper pillar, and the center of the array eye Below, there are more than three hundred Blue Demon Crystals with good materials. The largest one may belong to the Demon Lord or even the Demon Lord."

"I don't understand..."

Caiying was stunned, "Thirty-three days of materials, the power source of the demon world...what is the formation?"

"I have never seen the formation, but it is a bit similar to the formation of Anding City."

Zhou Shu groaned, "There should be some form of transformation or creation of chaotic power. The material used is likely to be gray fog."

Caiying was a little dazed, "Huh?"

Zhou Shu slowly said, "Simply put, this is a secret base for a certain force to study the power of Chaos. Judging from the degree of wear and tear of the Blue Demon Crystal and the copper pillar, it has lasted for at least 20,000 to 30,000 years, and it was built after An Dingcheng. "

"Oh."

Caiying was puzzled and angry, "Who is that? Just study well. Why use Xuanhuangjie as an experiment?"

"It seems that those strange winds originated from the leakage of the power of the formations, not intentional. It seems that these formations have not been maintained for a long time, and problems are normal," Zhou Shu paused and shook his head. "But if It is said that the leaked power caused the strange wind, why did it deliberately blow around the Xuanhuang Realm? Could someone deliberately guide the strange wind, or even deliberately cause the leak?"

I thought that I would find the answer here, but I didn't. Instead, there were new doubts.

Caiying said earnestly, "We are waiting here. If there are people, we can always get them out."

Zhou Shu nodded, "You can try."

was looking at Tongzhu thinking, suddenly there was a strange whistle.

Within a few breaths, rustle, swish, swish, louder and louder.

Caiying was surprised to point to the high platform in the middle of the copper pillars, where the front is located, "Zhou, came from there!"

Before the voice fell, tens of thousands of copper pillars suddenly lit up together, and the entire hall suddenly became like daylight, and those ancient runes flashed back and forth like stars. There was no pattern, but it was chaotic and the sound became louder and louder. , The high platform began to vibrate, and the entire fortress trembled. After a few breaths, the high platform became extremely hot, like burning charcoal.

嘭!

A red light flashed, and a solid shock wave rushed straight into the pipe.

Bang, bang, faintly bumped into the pipe several times, changed direction, and then disappeared.

"what?"

Caiying is still in a daze, Zhou Shu has already flown out.

On the right half of the fortress, the shock wave came straight out, breaking through the thick gray mist, engulfed in a large cloud of gray mist and a few unknown fog demons, rushed into the void along the edges of the heavens and disappeared quickly.

"Caiying, come on."

Zhou Shu immediately followed.

Caiying also turned into a sword light, followed closely behind.

"This is so fast."

"It's already considered slow, if I didn't hit it a few times."

Zhou Shu has already begun to calculate the deduction, he wants to determine the impact of the impact on the shock wave.

After 　　 followed for five days, Zhou Shu stopped and Caiying asked suspiciously, "Why didn't you follow?"

"It's unnecessary."

Zhou Shu shook his head. The shock wave has formed the prototype of the strange wind. If it continues, the strange wind will be reproduced. The process is the same, and the trajectory is the same. Based on the data of these five days, he has deduced thousands of times. The result is the same every time, there is nothing wrong.

Obviously, it was those few impacts that changed the direction of the shock wave that caused the strange wind to rush to the vicinity of the Xuanhuang Realm.

It is not difficult to solve this problem. There are many ways, but the problem is not here.

Caiying nodded, "I don't understand, but what you said is correct. Let's go to Xuanyi Realm?"

He paused, "No, let's go back to the fortress."

Caiying wondered, "Now go back? We don't care about the strange wind, there seems to be a fog demon inside?"

Zhou Shu shook his head, "Those fog monsters don't matter, they just test the Xuanyi Realm, and if there is a problem, we will solve it by the way when we return to the Xuanhuang Realm."

Caiying responded and followed Zhou Shu again.

back and forth, she didn't feel tired, she just wanted to find the persecutor of the Xuanhuang Realm as soon as possible to vent her anger.

Returned to the fortress and went around for a while, but there was still no one. After bypassing the still-working formation, Zhou Shu walked to the huge passage.

There is a gray mist coming from there, but it is not too much because it is restrained by the power in the formation.

As expected, this is the key to the fort. The material is dark iron, which is much higher than the fire copper. The passage is about three hundred miles long and the thickness is several miles, which is comparable to Anding City. There are a total of twenty-seven double formations in the middle of the .com channel, layered on top of each other. Obviously, these formations are used to block the gray fog and fog monsters on the opposite side, but now these formations are only debris left, which has long been destroyed.

It may be the leaked shock wave that damages the array talisman, or it may be the fog demon and gray mist on the opposite side.

Passing through the pipe, the right half of the fortress is more empty, without any buildings. In the gray fog, there are many array disks that have been destroyed by the gray mist. A very simple array disk is to release the vitality in the fairy material to attract the fog demon. , No one has maintained and replenished it for a long time, and the array has been invalidated, but there have been a lot of fog demons that have been attracted before, and the dense gray fog has formed a small fog demons group.

If it hadn't concealed its vitality, I was afraid that a bunch of them would pounce on it soon.

Seeing this, Zhou Shu seems to have a sense of enlightenment.

can basically be determined.

This fortress is a base for studying the power of gray mist and chaos, with formations on one side and gray mist on the other. Open the pipe in the middle to draw the gray mist and fog magic to study, and close it when you don’t need it.

Which force has such an idea, actually went to the edge of the heavens to study the gray mist, and why did you give up and ignore it halfway through the research? Is this hard-built fortress no more?
