"Wait a minute, I remember that you asked how to get the Heaven and Earth Crystal in the academy before, and you have only just ascended to the place of the Infant Transformation, there should be no Heaven and Earth Crystal, where did you get the Heaven and Earth Crystal to improve your cultivation?" At this time, Zhao Haiyun suddenly thought of something, looked at Bai Zhan and asked directly.

Bai Zhan said directly: "From Lao Liu!"

"Lao Liu?" Zhao Haiyun frowned slightly when he heard this title, looked at Zhao Mu with a confused look and asked, "Mu'er, is there such a person as Lao Liu in the academy?"

When Zhao Mu heard Lao Liu, he suddenly remembered what Bai Zhan said when he met Liu Lao who came out of the fryer before, and his eyes gradually showed a look of horror, but it was more of an unbelievable look, he didn't think that his guess would be true.

"Grandpa, the old Liu in Brother Bai Zhan's mouth may be Liu Lao. Zhao Mu didn't know if his series of conjectures were correct or not, but he still said this.

"Impossible!"

After Zhao Haiyun heard Zhao Mu's words, he directly vetoed it, after all, he was very familiar with what kind of person Liu Lao was, he was simply an iron rooster who couldn't pull out a dime!

"Lord Dean, what Brother Zhao Mu said is right, it is indeed my Heaven and Earth Crystal given by Elder Liu, and there are quite a few of them, otherwise, I will not be able to break through to the twenty-first Heavenly Scholar Realm. Bai Zhan suddenly said at this time.

After speaking, Zhao Haiyun and Zhao Mu were stunned again!

Peng!

At this moment, the door of Zhao Yunhai's study was suddenly violently pushed open from the outside.

Hahaha!

"Lao Zhao, you would never have imagined that I finally refined Hua Yuan Dan, and moreover, I also got a refining secret method for refining Hua Yuan Dan, this time, you must give me enough funds to buy spirit grass, and when I refine it in batches, you will wait to collect the Heaven and Earth Crystal." Laughter rang out as an old man entered.

Hey?

After finishing speaking, Liu Lao noticed Bai Zhan and Zhao Mu in the study, especially when he saw Bai Zhan, he hurriedly laughed and said, "Xiaoyou, why are you here?"

Seeing Liu Lao's attitude towards Bai Zhan, Zhao Haiyun and Zhao Mu didn't believe it no matter how they didn't believe it, and now they can be regarded as completely convinced.

"Lao Liu, in fact, I still have some alchemy things to teach you. At this time, Bai Zhan found that the relationship between Liu Lao and Dean Zhao Haiyun was extraordinary, since he couldn't get the Heaven and Earth Crystal from Zhao Haiyun, he could only continue to start with Liu Lao.

"What!Bai Zhan Xiaoyou, what you said is true?" Liu Lao didn't say anything else, but Bai Zhan's alchemy attainments were absolutely obedient, and when he heard Bai Zhan's words, he hurriedly asked with a gleam in his eyes.

Bai Zhan nodded and said, "Yes, but it can't be taught to you in vain, are you right?" ”

After Liu Lao heard Bai Zhan's words, he directly looked at Zhao Haiyun with a resentful look, and said directly: "Old Zhao, for so many years, I have refined countless pills for the academy, but I haven't asked for any benefits, now, I need heaven and earth spars to learn more esoteric alchemy techniques, you won't help!"

Hehe!

When Zhao Haiyun heard this, especially when he saw Liu Lao's resentful look, he hurriedly laughed dryly and said, "Help, why don't you help, you say, how much?"

"Bai Zhan Xiaoyou, you say, how much?" After Liu Lao heard Zhao Haiyun's words, he looked at Bai Zhan with a smile and asked.

Hearing Liu Lao's question, Zhao Haiyun on the opposite side had a black line on his face, it was so difficult, it was better for him to ask Bai Zhan directly!

"I will teach you three alchemy secret methods, is the price, just fifty times the heaven and earth spar you gave me before, don't worry, the alchemy secret method taught to you is definitely worth the price!" Bai Zhan looked at Liu Lao and said directly.

After hearing this, Liu Lao's face also changed, although he was eager to get Bai Zhan's alchemy secret method, but the price was fifty times that of the heaven and earth spar he gave before, that was not a small amount!

In the end, Liu Lao walked over and pulled Zhao Haiyun to a corner of the study, and the two began to discuss in whispers.

And Zhao Haiyun listened to Liu Lao's words, but he glanced at Bai Zhan with frightened eyes from time to time.

"Brother Bai Zhan, I suddenly regret bringing you to see my grandfather now, if I don't take you, you may be expelled from the academy directly, in that way, these things will not happen, you are really a mysterious guy!" Zhao Mu looked at Bai Zhan at this time and said.

Bai Zhan laughed after hearing this: "It's okay. ”

At this time, the discussion between Zhao Haiyun and Liu Lao had also ended.

"Little friend Bai Zhan, these are the heaven and earth spars you need. Liu Lao handed over the five spatial rings at this time and said with a smile.

Bai Zhan laughed after taking the five rings, and directly took out three jade slips and said, "See for yourself, it's definitely worth the money!"

"Lord Dean, if there is nothing to do, I will go back first, as for the intermediate class, I will not go first, I'm afraid, I will be able to go to the advanced class tomorrow. After speaking, Bai Zhan left Shu Shu directly and walked in the direction of his own accommodation in the accommodation area of the junior class.

"Old Zhao, do you want to go and see how this kid cultivates?" Watching Bai Zhan leave, Liu Lao asked with an extremely curious look.

Zhao Haiyun shook his head and said, "I still don't want it, this kid is a little evil, and besides, he flew up from the foundation building place, it's not simple." ”

And Zhao Mu, who had not spoken much, looked at the direction of Bai Zhan's departure at this time, and muttered to himself: "I am the strength of the Forty Heavenly Warrior Realm, and I have been stuck in this bottleneck for almost a year, if you suddenly surpass me tomorrow, I must fight with you, and I will let you know that the surge of strength is not the same as the strength that I have cultivated so hard!"

Bai Zhan, who returned to his residence, closed the door, and directly entered the Devouring Underworld, and took out all the heaven and earth crystals in the five spatial rings.

"Master, in this place of infants, your luck is not bad, you have obtained so many heaven and earth crystals in less than a day, and your strength has skyrocketed!"

After hearing this, Bai Zhan nodded with a smile and said: "Yes, my luck is really good, I thought that I would encounter danger, and it would be difficult to get the heaven and earth spar, but I didn't expect it to appear in Luohai Academy, one of the top ten colleges, and, to be honest, whether it is the dean Zhao Haiyun or the cold Zhao Mu and this old Liu, their temperament is not bad, otherwise, it may not be so smooth."

After speaking, Bai Zhan sat on the pile of heaven and earth spars, ran the Nine Dragons Battle Heaven Decision, and began to forcibly plunder the power of heaven and earth in the heaven and earth spars under him, and at the same time, the power of domineering plundering also broke out, speeding up the speed of absorption!

This time, it took Bai Zhan nearly three months to refine all the heaven and earth spars!
