The transmission array of the Seven Star Academy, going to the heraldic hall and Yaoguang Garden is different, and the four of them broke up in front of the transmission array and went to their own halls.

Yu Pu took Lu He to the heraldic hall, Lu He drank some wine, entered his room and fell on the bed, Yu Pu returned to Yu Lu, lit the wind lamp, the person had already sat on the bed, was closing his eyes and preparing to breathe, and the couplets at home dangled in his mind.

Sweat soaked in half of the fruit

The blood flow was reduced to a drop

"Father, I don't know if you're okay now, you wait for me, Dongling Continent, you wait for me......" Yu Pu didn't dare to think about his father's lack of news about the fall of life, he definitely wanted to go to Dongling Continent to find his father, this was his goal.

As soon as this couplet flashed in his mind, Yu Pu couldn't sit still anymore, he pushed open the door of Yu Lu, walked to the back mountain, and flashed, heading towards the snail cave, the path of cultivation did not stop for a moment.

Gathering Spirit Array, Pregnant Spirit Cocoon, put them one by one, but Yu Pu was in a round of Great Reincarnation Zhou Tian Pranayama, but found that the aura he absorbed was meager and limited, Yu Pu knew that his cultivation was improving, and the spiritual energy source he needed was also required to increase, and the spiritual energy source here could not keep up with his cultivation speed, so he had to find another place.

Thinking of this, he smiled slightly, since he came, let's continue here, Yu Pu took out one each of the wind and thunder crystals, absorbed them, and as time passed, the wind crystals and thunder crystals gradually turned into crystal powder, falling on the animal skins that he had already placed.

When it was dawn, Yu Pu collected the Spirit Gathering Array, went to the Xikeng Spring to wash it, changed into a new inner coat, put on a star suit, and returned to Yu Lu, but found that the two masters were waiting in his room, and he couldn't help but hurriedly step forward to salute the disciples.

"Look, I told you that Xiao Pu will definitely go over there to practice when he comes back, right" Master Liao smiled and said to Elder Cui, and then said to Yu Pu: "No need to do any salutation, come and sit down......"

Yu Pu had just sat down, and before he could sit up straight, Elder Cui suddenly asked, "Xiao Pu, I feel that your breath is different, ...... Have you broken your dignity?"

Yu Pu nodded, and Master Liao Hai also saw it, so he couldn't help laughing, and said: "It's really Venerable, Lao Cui, our apprentice is only sixteen years old, but he has already broken the Venerable and become a Venerable, you say, if we say it, who will believe it?"

"Since no one believes it, don't say it" Elder Cui looked at Yu Pu with a smile, and then said: "You are still so breathless, it is good for you to keep a low profile."

"En," Yu Pu responded.

"How about the foreign appointment this time......?" Liao Hai also smiled with a smile on his face, and asked Yu Pu and said: "I am old, but I always think about the experience of my youth, so I envy the foreign appointment, there can be many scenery, many stories, these experiences, will be a kind of wealth, come, let's talk about it, let us feel a ......."

Yu Pu briefly talked about the situation of this foreign appointment, and the two masters were in a state of turmoil when they heard it, and they were shuttling with Yu Pu's experience for a while.

"Xiao Pu, let me see the bursting flame bomb you just said" After Liao Hai listened, the first thing he asked was this.

Yu Puen sighed and took out two bullets from the ring, one was a burst flame bomb, and the other was a rage bullet without a coat of arms engraved on it.

Liao Hai and Elder Cui's two heads gathered together at once, the two first picked up the angry bullet, and then exchanged glances with each other, Elder Liao Hai faced the gap in the middle, the fingers of his right hand pulled a few times, the angry bullet actually cracked five petals, and the structure inside could be seen clearly, the two looked at it for a while, Elder Liao Hai closed the angry bullet again, and then took out the burst angry flame bomb, looked at the coat of arms on it, and put it under his nose to smell it, closed his eyes and checked the spiritual power, and then said to Yu Pu: "Xiao Pu, these two bullets are good in the heraldic hall?... ...”

Yu Pu didn't agree and nodded.

"This angry bomb should be a multi-production throwing weapon produced by Wumen, and there should be an auxiliary device for explosive cannons......" Elder Cui played with the angry bullet in his hand, and then said: "The middle layer is based on the principle of material expansion, and the inner layer wall has the explosion principle of sulfur, saltpeter, and black charcoal......

"Well, I saw it, I saw it a long time ago"

"If there is thunder ore powder, the gunpowder powder inside can pass through the pressure of the outside world, and then through the expansion of the middle layer, it can produce the bursting of the heart core and explode ......"

"Yes, it's the same as a thunderbolt, but it's powerful, hehe......"

When Yu Pu heard the thunder ore powder, his heart moved, and he thought about whether the thunder crystal powder could also be used, so he asked: "If you replace the thunder ore powder with thunder crystal powder, or directly thunder crystal, I don't know if it's okay?"

When Liao Hai and Elder Cui heard Yu Pu's words, their eyes turned round, and they exclaimed in unison, "Do you have a thunder crystal?"

"Well, there are not only thunder crystals, but also wind crystals, two masters, you can see ......" Yu Pu finished speaking, and the ring on his hand moved, and five thunder crystals and five wind crystals jumped on the stone bed.

Liao Hai picked up the thunder crystal, sensed it, and then said to Elder Cui: "Old Cui, this crystal is good, haha, this time, we can make the 'thunder' stock solution, haha, great"

Elder Cui also picked up the wind crystal, sensed it, nodded and said, "Well, yes, this crystal is good, I can also make this into a 'Storm' stock solution, and as long as there is a 'Wind Thunder Grass Whisker', we can also make a 'Wind Thunder Emblem Stock Solution'......"

"yes, we'll have to try, Xiaopu, how many Wind and Thunder Crystals do you have?"

"There are still a lot of ......" Speaking of this, Yu Pu took out the fifty rings where the wind and thunder crystals were placed, put them on the stone bed, and said, "There are all here, thirty wind crystals, twenty thunder crystals, ......."

Elder Liao Hai and Elder Cui's eyes widened, and then the two of them glanced at each other, each picked up one, went in to look at it, and then retreated, Elder Liao said to Yu Pu: "Xiao Pu, Lao Cui and I don't have much significance for the absorption of wind and thunder spars, and there are no students with wind and thunder attribute physique in the hall, just you, so, the wind and thunder spar is very important to you, so let's do it, I and Lao Cui each take ten wind and thunder spars, mainly for research, how about it?"

"I think it's okay......" Elder Cui nodded as he spoke.

Yu Puquan took out the wind and thunder spar, and took it seriously in his heart, the two masters wanted it all, and they took it, and now when they heard it, they said: "Two masters, this wind and thunder spar, the two masters can use it, just take it all, and the master will also cultivate......

Elder Liao Hai smiled and said, "No, no, this wind and thunder spar is actually not of much use to me and Lao Cui's cultivation, unless it is a higher-level spare, so these are all for research, ten is already a lot......" said, nodded at Lao Cui, the two of them each took ten rings, and then put the others in Yu Pu's hands.

Yu Pu didn't say much, he accepted twenty wind spars and ten thunder spars, at this time, he remembered something, and asked: "Two masters, just now I said that the principle of thunderbolt bomb and angry bullet is the same, before the words are finished, what ......about the next?"

Elder Liao Hai smiled slightly, and then said: "Although the principle of the angry bullet and the thunderbolt is the same, the internal structure is only somewhat close, and there is a big difference, the angry bullet is the core is compressed and exploded, so it needs an external gravitational spiritual power delivery device like a blaster, while the thunderbolt is a secondary explosion of the inner core after the exterior coat of arms is exploded, so the power of the thunderbolt is far greater than that of the angry bullet......"

When Elder Liao Hai said this, he picked up the Burst Fury Flame Bomb from the stone bed, and continued: "Just like your Burst Fury Flame Bomb, this is also the core reexplosion caused by the explosion of the exterior coat of arms, which can be regarded as a secondary explosion, but the power is still weaker than that of a Thunderbolt......

Yu Pu remembered that he had used a thunderbolt, and it seemed that it was not as powerful as a burst of rage, so his eyes looked at Elder Liao Hai, who was not a human being, of course, he saw what Yu Pu was thinking, so he laughed and said, "Did you compare the bursting flame bomb you are throwing now with the thunderbolt you used before, and find that it is not as powerful, right?" Haha......" Elder Liao Hai said this, laughed, and then exchanged glances with Elder Cui.

Yu Pu nodded, stood up, saluted the two masters, and said, "Please ask the two masters to solve your doubts......"

"Two differences, one, the structure of the thunderbolt and the thunderbolt are not all the same, although there is thunder stone powder in the thunderbolt, but the thunderbolt is the thunder stone powder and the thunder grass juice, oh, that is, the two you got from the last time you went to the thunder mountain, the difference in the main materials leads to the difference between the basic material of the thunderbolt and the basic material of the thunderbolt; Burst Emblem 'We all know that the explosion coat of arms is divided into, explosion coat of arms, blast coat of arms, burst coat of arms and blast coat of arms, so the power generated by the different surface coats of arms is also different, and also, when you used to use the thunderbolt, the cultivation was low, and now when you use your burst bomb, the cultivation is high, and the power is relatively strong, after all, spiritual power and true energy are not the same......"
