Yi He was a little scolded by the middle-aged mentor, he would never dare to disobey the words of a mentor, he glared at Guo Yi with some resentment, and hurriedly left.

Seeing Yi He's eyes, Guo Yi knew that he was hated by the other party, but Guo Yi didn't pay attention to such a person.

Maybe Guo Yi still needs to swallow his anger outside, but this is the War College, and as a core member of him, if the other party dares to come, it will definitely be boring.

Now that he has obtained the Streamer Nine Flashes, Guo Yi has no intention of staying in the academy, he still wants to take a good look at the cultivation method of the Streamer Nine Flashes!

Under the leadership of Daisy, Guo Yi soon came to the West Gate, and from here, he could go directly to Tiandu City.

"Daisy, thank you." Guo Yi said with a smile, Guo Yi still has a good impression of Daisy.

"Well, if Yihe makes trouble for you, you can come to Senior Sister!" Daisy said with a smile, she really saw Guo Yi's courage today, and she actually dared to play a fifth-order martial king.

Guo Yi touched his nose and didn't answer, Guo Yi didn't have the habit of letting women protect themselves.

After saying hello to Daisy, Guo Yi re-entered Tiandu City, and Guo Yi directly hired a carriage in order to hurry up.

It didn't take long for Guo Yi to return to Robinson's mansion.

"Huh! Brother Yi, why did you come back so soon? Robinson was a little surprised to see Guo Yi come back, he originally thought that Guo Yi would live in the War College!

"I got what I wanted, and of course I came back." Guo Yi said with a smile.

When Robinson heard this, he couldn't help but sigh secretly, in order to obtain the rich teaching resources of the War College, others had to fight to the death.

Now Guo Yi is good, he has the identity of a core student, but he disdains the War College and leaves as soon as he finishes his things.

"Brother Luo, I'll go back to the room first, it's okay, don't let people disturb me." After Guo Yi admonished him, he returned to the room.

Guo Yi sat cross-legged at the head of the bed, and then took out the jade that recorded the nine flashes of light, "It's really good to use this jade to record the exercises." ”

This jade is actually a rare magic prop, it can store a lot of information, as long as this jade is activated, the information in it can be automatically written into the mind, which can save a lot of time to climb.

You must know that advanced martial arts are very complicated, and if they are recorded in books, I am afraid that more than a dozen books will be written.

Taking a deep breath, Guo Yi urged the mana in his body and slowly injected it into the jade, and suddenly the jade emitted a dazzling light, and at the same time, a piece of information quickly appeared in Guo Yi's mind like a movie.

It took a full five minutes for Guo Yi to come back to his senses, and when Guo Yi opened his eyes, his eyes suddenly showed joy.

"If I cultivate this Streamer Nine Flashes, I'm afraid I will be able to escape even in the face of the Sixth-Order Martial Emperor!" Guo Yi sighed.

He didn't expect that the speed of this streamer and nine flashes could be so terrifying, and to Guo Yi's surprise, even if he didn't have bone wings, he could cultivate.

However, without the cooperation of the bone wings, the speed will be greatly reduced. Of course, the speed of the streamer is the top in the high-level martial arts, even if it is greatly discounted, it can be comparable to some speed-type intermediate martial arts.

With this streamer, Guo Yi can be said to have another life-saving hole card, so that even if he goes to the plateau tribe, Guo Yi has a little confidence.

"Dream, how is the research of the energy crystal?" Guo Yi asked after comprehending the nine flashes of the streamer.

Energy crystals can be said to be strategic materials for every country, and their role and importance can be imagined. It can be said that the effect of the energy crystal on Guo Yi definitely does not have to be a streamer.

"Preliminary research has been completed, and the energy contained in this energy crystal is very strange, it seems to be able to be converted into any form of energy, including electricity and mana." Dream said with some excitement.

Although the space bracelet has a light energy conversion system, a bracelet is so small, and the energy converted in a day is only enough for a dreamy daily consumption at most.

And during this time, he needed to help Guo Yi refine a large amount of pills, and the energy contained in the space bracelet was even more than enough to make ends meet.

For the sake of energy, Dream even hit the idea on the magic core, but it was too troublesome to call the energy conversion of the magic core electricity, and Dream has not yet developed a good solution.

And now after obtaining this energy crystal, all problems are solved.

"Dream, you say this energy can be directly converted into mana? Can that offer me to fight? Guo Yi asked in a hurried voice.

Guo Yi is happy that the dream can solve the energy problem, but even if he can't convert it for the time being, it doesn't matter, because Guo Yi doesn't need to refine the pill every day.

But if this energy crystal can be converted into mana, it will be completely different, then his combat power will definitely soar again, and his ability to continue fighting is not comparable to the people of this world.

Dream listened to Guo Yi's words, and immediately understood what Guo Yi meant, she said angrily: "You don't think too beautiful, although I can convert this energy into mana, but the energy contained in this energy crystal is too violent, and I can only convert it slowly." ”

"When you fight, your mana consumption is too fast, my conversion speed can't keep up at all, of course, even if you can't keep up with your consumption rate, but with me providing you with mana, your recovery ability is ten times that of others"

Hearing Dream say this, although it was not as good as he imagined, Guo Yi was also satisfied, with this energy crystal, in terms of continuous combat ability, he was definitely the top

"I think I should buy some magic items, I can't waste this killer weapon in my hand!" Guo Yi touched his chin and said.

The reason why the energy crystal can be used as a strategic material for a country is that the energy it contains can charge all magic items.

Especially those terrifying magic guide cannons, the energy consumed by one cannon can drain all the mana of a sixth-order martial emperor.

For such a thing, only the energy crystal can supply it with an endless source of energy.

In addition to the magic cannon, basically all strategic magic items in the military fortress need to be charged with energy crystals.

And with such a thing in his hands, Guo Yi must of course maximize its value.

"I agree with your approach, as long as I buy the magic props for me to process and install an energy storage device on them, then I don't have to worry about energy consumption at all." Dream said.

In the past, she was afraid that she would not have any energy, so of course she didn't dare to mention these opinions, but now that she has an energy crystal for her to squander, if she is given enough time, she can even make a battlestar.

"Okay, then we'll do this today." Guo Yi stood up and said.

Guo Yi has already planned, and after the banquet is held in three days, and after calming down the turmoil caused by the last competition, he will leave immediately, and all these preparations will be done in the past few days.
