With a dodge, Su Shen jumped over the defensive line of the tower base, appeared directly in the tower, and narrowly crashed into a feather clan.

Because he was still in a state of concealment, the other party didn't see Su Shen, he only felt a gust of wind blowing in his face, and instinctively waved his hand, seeing that he was going to fan Su Shen's face, Su Shen squatted down and avoided this fan. The Feather Clan had already stepped forward, and Su Shen had no choice but to retreat sharply, and then roll to the side again, narrowly avoiding this kick.

A cold sweat was not scared out of him.

Seeing that the Yu clan passed by him, Su Shen slowly stood up and walked inside.

The lowest level of the Chaos Demon Tower is actually a huge source array, and each room is a source array running point, gathering huge amounts of energy.

To Su Shen's surprise, the most people here were not the Yu clan, but a long-necked Zhi clan with three arms, the craftsman clan.

Artisans are born craftsmen who have three arms, the third of which is born on the back, and can work from top to bottom with both arms.

Their hands are naturally flexible, their fingers can even be bent against the joints, they are suitable for all kinds of delicate work, and they are naturally intelligent and love to create, so they are a natural race of craftsmen.

During the period when the Craftsman Clan was strong, its status was even stronger than that of the Five Great Zhi Clans, but the Craftsman Clan was not good at management, and their free and loose character made them unable to become strong. The Austrian tribe was better when it was there, with the Austrian tribe as the boss, they could play their own strengths as a vassal race, after the Austrian tribe was finished, the status of the craftsman clan plummeted, and finally they could only take refuge in the Yu clan, which had the strongest demand for the craftsman clan at that time, and they also experienced several betrayals and betrayals during the period.

Nowadays, as a race, the Artisan Clan does not have its own land, but lives by relying on major forces, among which the Yu Clan, the Spirit Clan and the Sea Clan are the mainstays.

The human race itself is an excellent craftsman, and there is little demand for the craftsman, while the tyrant is born without knowing how to respect technology, and obviously needs the craftsman the most, but they who advocate force cannot give the craftsman their due respect and status.

Now in this Chaos Demon Tower, there are a large number of craftsmen.

They crouched beside strange objects, containers, stoves, and source arrays, constantly controlling, recording, and occasionally making strange noises.

Some of the Feather Clan soldiers listened to their shrill shouts and wrote them down one by one.

It can be seen that the craftsman clan is the key to maintaining the operation of this huge demon tower.

The source array inside the base of the tower is very large, but it is basically controlled by "technicians", and there are no powerful figures in sight.

So Su Shen went all the way unimpeded, except for the moment when he just came in, he didn't encounter any danger again.

Walking at this moment, Su Shen saw a huge room in front of him, and countless craftsmen and feather clans were coming in and out of it, knowing that it must be the key to this place.

Su Shen walked over and saw a huge pillar leading straight below, and a large area of blood-red light surged out from the pillar of light, surrounded by countless craftsmen who were busy around this pillar.

At the top of this hall, you can vaguely see a purple celestial crystal hanging high in the sky.

Ziliu Tianjing is an extremely rare soul crystal, Su Shen has seen it once, just the size of a little thumb costs millions of source stones. And now the piece in front of me is the size of a human head, and this piece of Ziliu Tianjing alone will cost hundreds of millions of source stones. The most important thing is that this thing has no price, there is no place to buy it, and I don't know where the Yu clan got it.

At this moment, a purple smoke appeared on the purple celestial crystal from time to time, and a roaring sound could be faintly heard, with an indescribable coercion. The terror brought by this cry was extremely powerful, and at that moment, even Su Shen felt his heart swaying, and he felt a sense of boundless fear and wanted to shout. Fortunately, he activated the spiritual wall for the first time, which was able to resist the huge terrifying power contained in this cry, and his forehead was also so frightened that sweat flowed.

There was no danger all the way, and they all arrived at the core area, but suddenly they came like this, and it was impossible to say that they were not frightened.

This should be a purely soul-level attack, but it is not a conscious attack, it is completely the result of the majesty of a strong being's instinct.

What kind of life can have such terrifying majesty? The answer may be this beast.

But isn't this beast demented?

Why such angry roars?

Su Shen faintly felt as if he had touched a little bit of the edge of the Chaos Demon Tower's mystery.

However, there is one thing that needs to be noted, that is, this roar makes him feel unbearable, how can those relatively ordinary craftsmen and feather clans resist?

He looked closely at those craftsmen, and saw that each craftsman had a strange accessory on his body, exuding fluctuations, but it just resisted the soul shock brought by this afterlife.

"I see. Su Shen somewhat understood.

It seems that these accessories are not only a sign of identity, but also a way to screen intruders. If anyone sneaks in here without knowing it, and is shocked by the soul of the desolate beast, I am afraid that they will be scared at that time. However, Su Shen had a spiritual barrier, but he escaped this catastrophe.

But after passing this level, it seems that there is nothing to stump him here.

Thinking of this, Su Shen boldly entered the hall.

Unexpectedly, as soon as he stepped into the room, he saw a flash of light above, but Su Shen's figure automatically appeared.

In a busy hall, a person appears out of thin air like this, and it is impossible to say that it does not attract attention.

In an instant, countless eyes fell on Su Shen, and at the same time, he showed a look of surprise.

Su Shen was also shocked in his heart, he didn't expect that after the soul shock, there was still a real light in this room, and any disguise could not be hidden under this true light.

Now that they've been discovered, do you want to kill them all?

Su Shen was thinking so, but saw a craftsman bow to him and say, "It's Heyang Da Yu?"

Well?

Su Shen took a moment, and then noticed that the true light not only cracked his concealment, but also illuminated the storm wings he was hiding behind him.

So in the eyes of those craftsmen, it was a feather clan who appeared here.

The internal unity of the Yu clan is extremely high, and the defense of the Chaos Demon Tower is not external and internal, probably there are still some big feathers coming here today, so those craftsmen naturally misunderstood Su Shen and regarded him as a certain high-level Yu clan. As for the way Su Shen appeared, it can only be understood that everyone has their own quirks, and this Da Yu may just want to try the defense level of the demon tower.

Thinking of this, Su Shen coughed lightly and said, "Well, everything is okay?"

The craftsman replied respectfully: "Back to Heyang Dayu, the chain of shallow sea has been replaced, and there are a total of thirty-one deep source crystals, but you have to hand them over?"

Su Shen was stunned.

Su Shen didn't know about the chain of shallow seas, but Su Shen knew about the deep source crystal, which was a very peculiar source energy crystal.

It is different from the source stone, which is a source energy storage substance, and it is rich in a large number of impurities, so it can only be used for routine repairs, and is not suitable for cultivation.

The Deep Source Crystal is a pure source energy crystal that can be used for cultivation.

Of course, if this material is used for cultivation, it will be wasted, it actually has great auxiliary significance for many source techniques and arcane cultivation, and it can also be used as a special material for making special source energy items such as source arrays, puppets, and source devices.

If a source weapon is inlaid with a treasure like a deep source crystal, the power is not increased by a little.

The Deep Source Crystal is unique to the Yu Clan and never makes a move. The only way for the other clans to obtain the Deep Source Crystal is to kill the Feather Strongman and obtain an undamaged Deep Source Crystal from their Source Energy item.

Because of this, the Deep Source Crystal has always been a sky-high price in the Terran realm, and it will never appear on the Terran purchase list.

At this moment, I heard the craftsman ask him if he had thirty-one deep source crystals, whether he wanted to hand them over, and Su Shen was also very happy.

And such a good thing?

He was about to nod and say hand it over, but after thinking about it, there were already so many good things in his hand, such as the blood of the desolate beast or something, and he didn't have a chance to use it until now, and it wasn't bad for this deep source crystal, so he said, "Don't worry, I'll take a look around first." ”

He wanted to see how it worked first.

When the craftsman heard this, he paused for a moment and asked, "What does Da Yu want to see?"

When he fell into Su Shen's eyes, a strange feeling suddenly appeared in his heart.

After thinking about it, he said, "You can show me how it works." By the way, what's your name?"

The craftsman bowed his head and replied, "Little craftsman Yungong." ”

"Yungong, you take me around here. Honha is the first time to visit, so it is natural to take a good look at the operation here. ”

“…… Yes!" the craftsman hesitated for a moment, and finally took Su Shen to observe everything here.

This is the core center of the operation of the Chaos Demon Tower, and all the secrets are naturally presented in front of Su Shen's eyes. It's just that it's a matter of urgency to see or not understand, so along the way, Su Shen asked this craftsman some questions, intentionally or unintentionally, and knocked on the side to get some information.

This craftsman is also interested, and he will answer whatever Su Shen asks.

So soon Su Shen understood the biggest doubt he had all along, or one thing that all the Zhi Clan couldn't figure out - why did the desolate beast live?

Su Shen also had many guesses, and it turned out that one of his guesses was right.

The answer is the Chain of the Shallow Sea, that is, the Endless Source Power Sea.

The Endless Source Power Sea is the source of the source power of the Source Desolate Continent, located in another layer of space, but it continues to infiltrate the source power through mysterious spatial rifts to enter this place, forming a cycle with the Source Desolate Continent.

Some people say that the reason why the Source Desolate Continent is short of source power is because the Source Force Sea is constantly moving, and it is getting farther and farther away from the Source Desolate Continent, causing the source force circulation to become weaker and weaker.

Therefore, in order to obtain great power, many people are also exploring the sea of source power, and they have a lot of experience because of this.

It's just that when it comes to the spatial level, it's never easy, so even if you have occasional gains, it's difficult to promote. And any existence that can use the power of the Endless Source Force Sea is great.

Back then, Sky City was trying to obtain a steady stream of energy from the Endless Source Power Sea and was set in a fixed airspace.

Although this was a failed experiment, it still gave the Yu clan a lot of relevant knowledge.

When Sky City couldn't move because of this, the Yu Clan proposed that since they had already mastered some of the knowledge about extracting the energy of the Source Power Sea, why not use this knowledge to create another Sky City?
