"Master, is the name of the Sea of Illusion also related to this monster? Chu Du guessed after hearing the name Mirage, after all, Chu Du had heard a lot of legends about mirages in his previous life, it is said that the illusory scene of mirage is mirage, and the word vanity happens to describe these boundless things, combined with mirages, so Chu Du guessed that the name of the Sea of Illusion is also connected with mirages.

"You guessed right, the Sea of Illusion can be said to be a gathering place for mirages, not only this ninth-level mirage is in it, but also countless mirages that are weaker than it live in it, the mirage spewed out by these mirages covers the top of the sea all year round, and the monks who pass by must not only be on guard against the attacks of the demon beasts in the sea at all times, but also be careful that they fall into the mirage, once they fall into the mirage, the monk will be greeted by endless illusory illusions, so it is indeed caused by the mirage to be called the Sea of Illusion. Yin Hao confirmed that Chu Du's guess was completely correct.

After saying this, a light blue pigeon-egg-sized bead floated in front of Yin Hao, and then this bead flew towards Chu Du under Yin Hao's control.

Chu Du took it and put it in the palm of his hand and looked at it and asked, "Master, what is this bead for?"

"This bead is called the Concentration Pearl, this time through the sea of illusion can rely on it to avoid the formless and colorless mirage, this bead is made of a very rare bird in the sea of illusion called the spirit bird demon beast demon core refining, it is said that the spirit bird can naturally sense the invisible and colorless mirage, can freely shuttle in the sea of illusion, with the spirit bird demon core made of this bead also has such a function,

And this bead is also added to other artifacts when refining, when you wear it, you can not only find the mirage in advance, but also clear your mind, even if you fall into the mirage, you can see through the illusion, break free from the illusion, I relied on this bead last time to successfully pass the sea of illusion. Yin Hao introduced the role of this bead to Chu Du.

"The world is really full of wonders, with such a powerful mirage, but there is a bright spirit bird that is not afraid of mirage. Chu Du couldn't help but praise Yin Hao's words after listening to them.

"The world is so big, how can we little monks be able to explore the clear, okay, these are nothing to sigh about, now there is no mirage here, the effect of the early warning of the Concentration Bead cannot be revealed, but there is another effect You can try, you can inject mana into the Concentration Bead." Yin Hao said to Chu Du.

Hearing Yin Hao's words, Chu Du's heart moved, and a true spirit crystal in the dantian turned into a true spirit qi gushing out of Chu Du's palm and entered the Divine Bead, and then Chu Du was immediately wrapped in the faint light emitted by the Divine Bead, and Chu Du in the bright light felt a cool feeling pouring into his mind, which made Chu Du feel that his thinking became extremely clear, and then Chu Du tried to operate his divine sense, and found that the current divine consciousness was more easy to control and freewheeling, Chu Du felt that now his divine consciousness would definitely detect a farther distance。

Yin Hao looked at the joy on Chu Du's face, smiled and said: "To put it bluntly, the function of the Concentration Bead is to enhance the spiritual power of the monk, and once the spiritual power is strong, all kinds of illusions will naturally not confuse people." ”

Chu Du stopped continuing to transmit mana, and the light emitted by the Concentration Bead immediately dimmed, and the cool feeling in Chu Du's mind disappeared immediately, and the true spirit crystals consumed in the dantian were instantly replenished by the Taiji Ball after refining the spiritual energy that was automatically absorbed into it.

"Master, isn't the formation that helps draw the power of the stars also strengthens spiritual power. Chu Du thought of the question of needing the help of the formation behind the refining body and said.

"It's about the same, but the spiritual power enhanced by the formation is much larger than this bead, and only our body refiners can temporarily forcibly withstand this huge spiritual power increased through the formation. Yin Hao affirmed, and at the same time did not forget to show off the superiority of the body refiner.

Chu Du automatically filtered Yin Hao's words later, and instead asked, "What is the name of that formation, and are those materials easy to find?"

"The formation is called the Nine Yuan Regents to return to a large array, the materials are absolutely not found on the Tianyu Continent, and it is still better to match after going out, by the way, I will give you the list of materials needed for the formation now, and the array disk will also be given to you." While Yin Hao spoke, a piece of jade slip and a formation disk flew towards Chu Du again.

After Chu Du raised his hand to catch these two things, he took a closer look at the array plate that seemed to be like a compass, and found that this small disc was engraved with a lot of mysterious lines and inscriptions, Chu Du had not learned a spell now, of course, he couldn't understand the inscriptions used in these arrays and talismans.

"The array plate is a prop that depicts various formations, and this array plate depicts the Nine Yuan Regents returning to a large array, and after using mana or spirit stones to excite, the materials needed can be placed in the right position to play the role of this large array. Yin Hao explained to Chu Du, at this time, Yin Hao found a trace of being a master again, no matter if you have a treasure against the sky, the cultivation speed is terrifying, and there are some things you still have to ask the master to know.

Chu Du poured mana into this array again, this time a true spirit crystal was not able to activate the array, but Chu Du continued to instill mana into the array, until the mana of 30 true spirit crystals was instilled to activate this array, only to see that with the array disk as the center, nine black dotted lines extended around, and a circle appeared at the end of these black lines, and these circles kept flashing with inscription symbols.

And directly above the array disk, a circle with flashing inscriptions also floated out of thin air.

Chu Du couldn't help but be amazed when he looked at this scene.

"Those circles are the places where the materials are placed, and the formation is really activated after the materials are placed on it, and according to the different levels of materials, the amount of spiritual power that the formation helps you increase is also different. Yin Hao pointed to the circles on the ground and explained, and then Yin Hao pointed to the circle in the air and said, "This is the hub where the formation and your spiritual power are connected to each other. ”

Chu Du nodded and said that he had written it down, and after putting away the array disk, Chu Du probed his divine sense into the jade slip to observe all the materials needed for the formation, and after a while, Chu Du withdrew his divine sense, but a strange look surged on his face.

"Master, this formation requires the demon cores of some demon beasts with strong spiritual power, which is understandable, how can a living person also use it as a material?" Chu Du asked a little speechlessly.

"What's so hard to understand about this, it's difficult to control the demon beasts with strong mental power, so they directly take their demon cores to make materials, and people are different, as long as they are given benefits, this kind of work to make materials is done by people, and this formation will not harm their lives, at most they will be mentally depressed for a while, this formation is actually to temporarily turn other people's spiritual power into their own spiritual power, and it will be returned to people after the end, of course, the demon core can't be returned. Yin Hao looked at Chu Du with an expression that you want to learn more and remember more.

Chu Du naturally accepted it with an open mind, which made Yin Hao extremely satisfied.

"Fortunately, my space is large enough, otherwise I would have to go outside to cultivate, and I would be blind to the role of my companion treasure. Chu Du looked at the long lines that stretched out and said, each of these black dotted lines is almost 50 meters long, and the general space is really not enough to cast this formation.

"I really don't know what good things you did in your last life to be able to get such a good baby. Yin Hao complained after hearing Chu Du's words.

Chu Du smiled silently, he was just an ordinary college student in his last life, and he didn't even dare to help his grandmother, but he didn't do anything good, maybe he saved a certain universe in his last life.

Chu Du put away the jade slip and the array plate and put it away, now the generally important things, Chu Du will be placed in the system space, some of the more common items used at the same time Chu Du is placed in the storage ring, so it is convenient to pick it up, and when it goes out, his own space is still not known to people as much as possible.

"So have you explained everything in the future, and decided when to leave?" Yin Hao said to Chu Du.

Chu Du heard these words a little awkwardly, Chu Du thought about it and said: "It should be nothing, I have already met the master and junior brother before coming in, and I don't want to alarm other people, just leave in the next two days." ”
