"Academician Lin, since you have already admitted defeat, why don't you admit this fact? ”

"This sword is an immortal magic weapon, and there is only one person in the mountain pavilion who has the ability to refine an immortal magic weapon, but Dean Qingfeng is alone, what are your chances of winning?" Chu Shiyi said to Tianyu, she didn't know what Bai Yu's words meant, I admit defeat not because I lost, but because I don't want to teach you anymore, the relationship is still that we lost, and he doesn't look down on us.

"It's nothing, the bet is still the same, your first class of the Heavenly Rank will be taught by Vice Dean Ying! ”

"Vice Dean Ying has no objection to this!" Tian Yu asked Vice Dean Ying on the side.

"Academician Lin, you really ......" Vice Dean Ying asked puzzledly, according to Tianyu's ability, refining a handful of immortal weapons can crush Chu Shiyi, the treasure of the Zhen clan, why did he want to do this?

"You should announce it, vice president! It just so happens that the people in the first and second classes are here, and I will make it clear in front of them. Tian Yu ignored it and said.

"Okay!" Helplessly, Vice Dean Ying continued, "From today on, Academician Lin is responsible for teaching the second class of the Heavenly Order, and I will teach the first class of the Heavenly Order, everyone has no objection!"

As soon as the words fell, the whole class was noisy, and most of the voices were divided into two streams, one was from the first class of the Heavenly Order, and they were glad to have driven away Tianyu, and the other was from the second class. Obviously, they also protested a little, and inexplicably they were assigned from Vice Dean Ying's students to Academician Lin's subordinates.

"Class 2 students, in order to prevent you from questioning my strength again, I can demonstrate the refining weapon on the spot, and then you decide whether to be my student or not. Tian Yu stopped them and said. He didn't want the same class to be in the same class again, so he couldn't stop teaching all the classes.

"Good ......" The people in the second class suddenly sighed, after all, they also wanted to see Tianyu's strength, even if they beat Jiang Chengqing last night, it could only be attributed to his two demonic beasts, as for their own strength, and alchemy skills are unknown.

"Vice Dean Ying, what is the level of this Fire Vein with the highest specification from the Mountain Pavilion?" asked Vice Dean Ying of the Tianyu Chao.

"It's the immortal fire vein of the Lizi Pavilion on the top floor of the Lishan Pavilion, and generally only the dean occasionally uses it, Academician Lin, do you need it?"

"Lead the way......," Tian Yu said.

Suddenly, everyone was stunned, the immortal product fire vein, does he want to refine the immortal weapon? Impossible, the immortal weapon can only be refined by Dean Qingfeng, even if the other academicians can only refine the secondary immortal weapon, it will be up to him to see how he ends up when the time comes.

"Sir, can you really refine immortal weapons? Bai Yihan thought for a moment, and then felt a little sure in her heart, after all, on the day she apprenticed, Tianyu gave her Zhongshan Wind and Rain Sword with immortal weapons, immortal weapons are very rare on the mainland, if you can't refine immortal weapons by yourself, people who send immortal weapons like this are definitely losers.

"Okay. Vice Dean Ying said, and at the same time, without anyone noticing, he crushed a communication jade slip with his right hand. Immediately, the group walked towards the top floor of the Lishan Pavilion and the Lizi Pavilion.

Off-the-top floor:

"Interesting. Tian Yu looked there, and saw that the other three academicians from the Mountain Pavilion at this time, including Dean Qingfeng, were all standing there, as if they had been waiting for a long time.

"I've seen the dean. The group bowed to the breeze.

"It is said that Academician Lin wants to refine the weapon again, I wonder if we can copy and learn?" Qingfeng asked with a smile.

Suddenly, the people in the first and second classes of the Heavenly Rank were all stunned, what? Dean Qingfeng has to learn to copy, you must know that Dean Qingfeng is a person who can refine immortal weapons, and they are all like him to copy and learn, so how strong is he!

At this time, Chu Shiyi was also stunned, what kind of situation was this!

"The dean is serious, let's study together!" Tian Yu smiled.

"Then please!"

I saw that the door of the Lizi Pavilion opened, and suddenly a space of more than a hundred zhang in size appeared, only to see a meandering and bubbling fire vein through the middle of the Lizi Pavilion constantly churning, and the whole room became red under its scorching.

"It's so hot!" Those students couldn't help but be stunned, this is the immortal fire vein? If you want to stay, you can't stay for long!

"I don't know if you academicians have refining materials??I forgot to bring it when I went out in a hurry today?" Tian Yu said as he looked around at the academicians. In fact, it's not that Tian Yu didn't bring it, but that Tian Yu didn't have it at all, Tian Yu is different from other academicians, he himself is a poor mortal monk, and the most precious thing in the storage ring is the spar, where there are refining materials!

"I have a set of refining materials here. Vice Dean Ying flipped over a storage bag with his right hand and handed it to Tian Yu.

"Yes, the materials are of a very high grade. Tian Yu took out the materials and saw that this series of materials had the quality of immortal products.

"This is the material I originally raised for refining a fairy sword, I have already collected this material, but I don't have this refining ability, so the refining can be stranded, and today the materials are in the hands of Academician Lin, which is the so-called exhaustive use!" Vice Dean Ying said ashamedly.

At this time, Chu Shiyi was stunned again? Could it be that he can really refine immortal weapons? No, he can only explain the problem when he refines it. Then she thought negatively.

"Thank you, Vice Dean Ying, so be it! No matter what grade the refining magic weapon is today, it will all be given to you, Vice Dean Ying. Tian Yu smiled.

"Thank you, Academician Lin. Vice Dean Ying was so excited that he hurriedly bowed his hand, in his opinion, this refining weapon is undoubtedly an immortal weapon, and how exciting it is to get an immortal weapon.

At the same time, the other three academicians looked at Vice President Ying with envious eyes, and they regretted that they didn't take it out earlier.

"Alright, I'm here. Immediately, Tian Yu flipped his right hand and directly threw the refining materials into the fire vein.

"What, he ......" Suddenly everyone, including Dean Qingfeng, was stunned, what was he doing like this?

You must know that refining weapons are basically refined in the refining furnace, powerful people like them, academicians like them can use the condensation of heaven and earth elements as refining furnaces, and this academician Lin directly threw the materials into the fire vein, could it be the refining furnace in the fire vein?

No, all the academicians were stunned, they saw the clue, he was purifying the refining materials, but the refining materials were already immortal products, what grade did he want to purify?

"Academician Lin, are you purifying?"

"Yes. Tian Yu nodded, he didn't deny it, he wanted to refine the secondary artifact, and the purity of this material was obviously not enough.

"But this material is already an immortal product!" asked Vice Dean Ying puzzled.

"Believe me, I naturally have my own refining method for doing this. Tian Yu smiled slightly.

"However, we still need the help of academicians. Tian Yu suddenly said to the four academicians and Dean Qingfeng.

"Academician Lin, what do you need help with?" Qingfeng also asked puzzled.

"With this immortal fire vein, it will take at least twenty days to purify the refining materials to the level I want, I don't think everyone wants to wait here for me to refine the weapon after twenty days! If the five academician deans inject the elemental power into the fire vein, they can increase the purification speed, and if it goes well, with the cultivation of the five people, three hours should be enough." Tian Yu said, it is too difficult to wait for twenty days to purify the fire veins alone, since there are these academicians here, why not let them help. It's not a foul, it's just twenty more days to call or not.

All the academicians were stunned, it would take twenty days to purify the fire veins with the immortal products, what grade did he want to refine?

"In that case, let's all move!" Dean Qingfeng did not hesitate to inject the power of a natal element into it, and suddenly the academicians of the other four martial saints did not hesitate to inject energy into it one after another. They also wanted to see what grade of magic weapon Tian Yu was going to refine.

"Sir, if you want to refine the immortal materials, do you want to refine the secondary artifact?" Bai Yihan on the side couldn't hold back the excitement in his heart and asked.

"You'll know when the time comes. Tianyu scratched Bai Yihan's nose and said.

"Hmph. Bai Yihan glanced at Tianyu.

As time passed little by little, two hours passed in the blink of an eye, and the blessings of the five great martial saint energies did not pause. Tian Yu frowned and looked at the material, faster than expected. He secretly thought to himself in his heart, due to the continuous blessing of the power of the five great martial saint elements, coupled with the training of the energy of the fire vein, the purity of this material had reached the requirement for a full hour.

"From. With a wave of his right hand, Tian Yu suddenly became a cloud of liquid, suspended in the air under the pull of the five energy paths, and at the same time, the majestic energy continued to emanate in the sky.

"Without my orders, the Academicians must not withdraw the elemental power first. Tian Yu looked at the flying material and said.

"This material has already surpassed the immortal product, and it seems to be a sub-artifact level. Could it be that he wants to refine a sub-artifact, if so, it would be terrifying. At this time, Qingfeng also looked at the mass that had turned into liquid and thought to himself.

"Sub-artifact?" Suddenly, all the academicians sensed the quality of the material.

"This is impossible!" "There is no one on the continent who can refine a secondary artifact at all, could it be that this young man is really going to refine a secondary artifact?"

After all, if you want to refine immortal artifacts, the materials of Vice Dean Ying are enough to refine, and there is no need to purify them at all.

"Ladies and gentlemen, listen carefully to Academician Lin's deployment today, if that is really the case, the first secondary artifact of the Xuantian Continent may come from here. Qingfeng Divine Sense transmitted the sound to all the academicians, and then looked at Tian Yu who was staring at this material at this time, although he couldn't believe it, but all kinds of signs indicated that Tian Yu was preparing to refine a secondary artifact.

"Academician Lin, I wonder if you are preparing to refine the sub-artifact?" Just after the Qingfeng transmission ended, an academician asked Chao Tianyu, this is also a question that everyone is looking forward to.

"This, you will know when the refining is completed, and it won't take long, at most, three or four hours. Tian Yu didn't deny it, but said so.

And this is the kind of reply that many academicians all acquiesced, the secondary artifact, I was actually able to participate in the refining of the secondary artifact, and many academicians were stunned.

He wants to refine a secondary artifact. At this time, although the first class of the Heavenly Rank and the second class of the Heavenly Order could not see the Ming Hall of the material, they also saw the clues in the conversation between Tianyu and the academician. They originally thought that Tian Yu came to the Lizi Pavilion with immortal fire veins to refine immortal weapons, but they didn't expect that they were going to refine secondary artifacts.

"Sub-artifact?" At this time, Chu Shiyi also muttered three words in a daze......
