In order to fulfill the last wish of the bad old man, in exchange for 600,000 contribution points, as well as system tasks.

Ning Chu had to start thinking about revitalizing the 'call' door.

And the core of revitalizing the 'Summoning' Gate is to allow most people to practice the 'Soul Summoning Technique', Ning Chu thinks that he doesn't have this ability, so he can only rely on the system.

"Xiao Zhao, how's it going?"

Ning Chu came to the system and handed over the 'Soul Summoning Technique' mental method to Xiao Zhao.

After all, she is an 'infinite summoning system', and this 'soul summoning' is nothing more than a drop in the bucket for her.

"Master, I've read this exercise, and I can improve it. ”

"Really?"

Ning Chu showed joy, although he was very confident in Xiao Zhao, he was inevitably a little apprehensive, and the stone in his heart finally fell at this moment.

"But ......"

Xiao Zhao made a long sound, which made the smile on Ning Chu's face immediately solidify.

"However, after the improvement, the effect will be affected to a certain extent. ”

"How?"

Xiao Zhao tilted his head and thought about it, and suddenly raised his jade hand and grabbed it in the air.

A translucent white cube immediately appeared in front of her and Ning Chu, and then Xiao Zhao stretched out his hand and clicked, and a small blue dot of light immediately appeared in the middle of the cube.

"Master, this cube is equivalent to the space we are in, and the 'Soul Summoning Technique' is the point of light in the middle, when we urge the exercise to operate, the light will be projected on all sides, and then the living beings on the surface will be projected into the cube, and a summoning will be completed. ”

"I see, but why can't I use it now?" this was what Ning Chu was curious about.

Xiao Zhao reached out and snapped his fingers when he heard this, and the translucent cube immediately turned into a black entity, and he could no longer see the light points inside.

"Just like this, if the six sides of the cube are blocked, the light inside cannot be projected to the outside, and naturally it will not be able to attract the creatures on the surface. ”

"I see. ”

After listening to Xiao Zhao's explanation, Ning Chu suddenly realized.

That cube is equivalent to this world, and the six sides represent different territorial spaces, once blocked by the barrier, the spirit summoning technique cannot get in touch with the creatures inside, and naturally it cannot be used.

But then Ning Chu thought of another question.

"But why can't the creatures in this space be summoned?"

"Because there is no 'calling mark'. ”

"What is the 'Summoning Mark'?" Ning Chu was like a curious baby of more than 100 pounds, giving full play to the fine tradition of asking questions if he didn't understand.

As the spirit of the system, Xiao Zhao naturally answered all questions to Ning Chu, and was very patient and gentle.

"Because there is a force that interferes with the projection of the 'Soul Summoning Technique', if you want to summon a living being, the other party must have a 'Summoning Mark' on it, otherwise it will not be able to be induced. ”

"I seem to get a little bit of it. ”

Ning Chu's brows stretched, and the doubts in his heart suddenly cleared up at this moment, isn't the 'summoning mark' in Xiao Zhao's mouth equivalent to the signal of a mobile phone.

It's like the analogy that Ning Chu made before.

A good mobile phone, with electricity and phone bills, but it just can't make calls, the reason is that there is no signal.

Contact can only be made when both phones have signals, and this 'summoning mark' is equivalent to the signal of mobile phones.

It's one thing to know the principle, but it's another thing to actually do it.

"So how do I get the 'Summoning Mark'? What is that?"

"'Summoning Mark' is a very rare field, as long as the spiritual power is attached to the formation when urging the 'Summoning Technique', the field can be formed, and it is not difficult to build, but how much area it can cover depends on the amount of spiritual power. ”

"Will you know how to form a formation?"

"It's simple, I can teach it to the master. ”

"Okay, teach me!"

Ning Chu was ready to be a qualified primary school student, but found that Xiao Zhao didn't teach him what he meant, but stretched out a white finger and lightly tapped it on his eyebrows.

"This ......"

The next moment, a stream of unfamiliar information flowed into my mind.

First, several points are lit up one after another, and then each point is connected into a line, with more and more lines, and finally a formation is formed.

It was more like a three-dimensional three-dimensional image, and the position and distance of each point were clearly imprinted in his mind, which was the first formation that Ning Chu learned.

Attaching spiritual power to this formation forms a field.

After learning the 'Summoning Seal', Ning Chu fell into deep thought.

Where is this field located?

If you put it in a mountain range, you may be able to summon some monsters, but the effect is not ideal.

First, the monsters in the mountain range are very mobile, and secondly, the strength is uneven, and the field built is also easy to be destroyed.

Therefore, the best way is to find a fixed location, where there are fixed demon beasts to live in, and the level is best to be high and low, so that disciples of different realms can be summoned according to their own strength.

"That's right, Beast Soul Forest!"

Ning Chu's eyes suddenly lit up, isn't there a ready-made place in the sect.

It is said to be a forest, but in fact, it is surrounded by several mountains, just behind the Hall of Elders, covering a very vast area, and it is the private land of the Royal Beast Gate.

Through the efforts of generations of disciples and elders, there are now many fierce beasts in captivity in the Beast Soul Forest.

From the Qi Condensation Realm (First Order) to the Immortal Realm (Eighth Order), there is even a legend that there is a Nine Heavens Phoenix Soul in it, and the high realm is terrifying.

The Beast Soul Forest is the key area of the Royal Beast Gate, and there are special elders and disciples in charge, and the management is very strict.

That was exactly the best choice for Ning Chu to arrange the 'Summoning Seal'.

After having an idea, Ning Chu no longer hesitated, dodged away from the system space, and returned to the Soul Summoning Peak, at this moment it was already noon, he did not delay, and rushed straight to the Beast Soul Forest.

However, as soon as he walked to the square, Ning Chu was stopped by a group of people.

A short boy rode on a large rhinoceros, followed by several disciples, each with a war pet by his side.

"Hey, isn't this the Holy Son who 'called' the door, I came to you just out of the customs, but I didn't expect this to happen. ”

It was the dwarf boy who spoke, and he looked average, but the rhinoceros under the seat was very attractive, especially the single horn on the skull, which constantly flashed with purple arcs, and it was not an ordinary beast at first glance.

Judging from the breath, this rhinoceros has reached the Great Perfection of the Gathering Spirit Realm (Third Order), and even stepped into the Jindan Realm (Fourth Order) with one foot, which is quite powerful.

"What are you looking for me to do?"

Ning Chu spoke indifferently, this young man was already very rude when he rode on a rhinoceros and talked to him, and there was an arrogant look on his face, and he looked like a pampered master.

And it can be seen from his costume that he should be the young master of a big family.

The young man sneered, looked at him with slanted eyes, and said, "Of course it's a challenge to you, is it possible that I can still invite you to dinner?"

"Hahaha......"

Several disciples beside him laughed loudly, and their expressions and movements were extremely exaggerated. After all, the boss is pretending to be thirteen, and they are actively coaxing to set off the atmosphere, which is the basic quality of being a younger brother.

"I heard that you defeated Wang Hu and replaced his ranking, I originally planned to challenge him when I came out, but now I have changed my attention, and today I want to taste the feeling of defeating the Holy Son. ”

"I'm going to ...... Well, I accept your challenge. ”

Ning Chu was about to refuse, but temporarily changed his tone.

Because it suddenly occurred to him that it was not enough to revive the 'Summoning' Door Light and improve the 'Summoning Technique', but also to make some noise to let everyone know the power of the 'Summoning' Door, so that it could attract people.

And the easiest way to increase popularity is to play!

Fight all the way!

Isn't the atmosphere of the Royal Beast Gate belligerent, then I will sing all the way and beat all the Tianjiao on the combat power list, and then the fame of the 'Call' Gate will naturally be extremely popular.

This is the best way to get the word out!

"But there's a rule to challenge me, you know?"

"Five hundred spirit stones as a bet? Hahaha, your holy son is really poor enough, just five hundred spirit stones can impress you, it's really cheap. ”

In the face of the provocation of the bull riding boy, Ning Chu did not fight-for-tat.

It's not that you don't dare, but you disdain.

The more fierce he screams now, the heavier he will be when he waits, which is extra care.

"I'll give you a thousand spirit stones, and it will be yours regardless of victory or defeat, come on. ”

The young man spoke proudly, and threw a thousand spirit stones directly to Ning Chu, looking like he was rich.

Ning Chu was not polite when he saw this, and directly put the spirit stone into the storage ring, and then looked at him with a smile: "For the sake of you adding chips, I will let you strike first." ”

"Arrogance!"

The bull riding boy's face turned cold, and he didn't see any movement, and a large number of purple arcs suddenly appeared around the rhinoceros under his crotch, holding the power of thunder, especially the single horn, which was more like a sharp weapon.

The next moment, the rhinoceros roared, causing the square to shake, and it crashed straight towards Ning Chu like a cannonball.

"Arrogant, even Wang Hu is not as good, and he dares to challenge me. ”

Ning Chu sneered and stomped his right foot on the ground.

"Xiao Zhao, give him a wave of ruthlessness. ”
