The black-robed man from the Yin Medicine Sect looked at Zuo Yu, and there was a demagogic gorgeous color in his eyes.

And then, this color actually gathered into a small knife and stabbed towards Zuo Yu's head, and Zuo Yu casually greeted him with a sword qi, but who knew that after the sword qi touched this knife, it was as if nothing had touched it.

"Huh?"

Zuo Yu's face changed, and then his third eye opened from his forehead, and a white light flashed.

Bai Mang shone on this knife, and the knife suddenly came to naught.

The black-clothed man of the Yin Doctor Sect above also changed his face, obviously not expecting that things would be like this.

"Mental attack, I didn't expect you to have this ability" Zuo Yu suddenly said with some surprise.

"You can actually crack my trick?" The old man on the other side was also taken aback.

"Spiritual power transformation, you are very good" Zuo Yu nodded, and then said: "But your spiritual power attack is still a little bit hot"

"What do you mean?"

"It means that your mental power is not strong enough"

After finishing speaking, Zuo Yu's eyebrows also condensed a sword, but it looked much more powerful and domineering than his previous knife, and this sword was very real, almost the same as a real sword.

"Go"

Zuo Yu waved his hand, and the sword immediately flew over.

When the black-robed man saw it, he condensed a small knife and killed Zuo Yu, but this time, the knife touched Zuo Yu's sword, and it was instantly defeated, and Zuo Yu then withdrew the sword and disappeared into the center of his eyebrows.

"Okay, I'll go with you"

"Is there anything you need to take with you?" asked Zuo Yu.

"No need, I have the space ring here, and I took away all the important things"

"Okay, come with me"

Zuo Yu finally took these people back to the Burning Sun Sect.

As soon as he arrived at the door of the Burning Sun Sect, Xuanqing had already come out with someone to greet him.

"Sun Sect?"

The black-robed old man behind him was taken aback for a moment, and then said, "How could this Burning Sun Sect have produced a peerless master like you?"

"Meet the Seniors"

A group of disciples of the Burning Sun Sect immediately saluted.

"Let's go in and talk."

After coming to the main hall, Zuo Yu spoke: "These three are people from the Yin Medicine Sect, I want them to enter the Burning Sun Sect."

When Xuan Qing heard this, his face suddenly changed, but then he nodded and said, "Come on, arrange a room for the three of you."

"Yes, Master"

One of the disciples immediately went to get ready.

"In the future, everyone will be a family, I hope everyone will help each other and unite as one," Zuo Yu explained.

"Seniors rest assured"

"By the way, how is your ancestor?"

"Shizu and his old man have broken through, and now they are stabilizing the realm, it is estimated that it will not be long before they can get out of the customs."

"Well, good, good" Zuo Yu nodded.

After a few disciples went out with the three old guys, Xuan Qingcai asked, "Senior, ...... this person from the Yin Medicine Sect?"

"What's wrong?" Zuo Yu asked.

"It's such a senior, this person from the Yin Medicine Sect was the public enemy of all sects before, and now he has been hidden for so long, if people know, it may bring trouble to my Burning Sun Sect" Xuan Qing finally said.

"You don't have to worry about this, do you think this earth is huge?"

"This ...... Seniors, juniors are dull"

"Do you remember the previous sign?" asked Zuo Yu.

"Remember"

"That brand, in fact, is just a token of the sect of another world, there are only three people left in the Yin Doctor Sect now, they have already received the punishment they deserve, so why bother staring at the old things?" Zuo Yu said lightly.

"The teachings of the seniors are remembered by the younger generations," Xuan Qing suddenly said solemnly.

"Well, remember, this world is too small, but I still have concerns, one day, you will know, who I am" Zuo Yu said lightly.

"The younger generation understands"

"Well, is Xuan Ming out of the customs?" Zuo Yu asked.

"Senior Brother Xuan Ming heard that you are back, and you were out of the customs yesterday"

"Okay, I'm going to open the furnace for alchemy, let him come and find it"

"Okay, I'll inform Senior Brother Xuanming"

“........”

In fact, after Xuan Ming heard that Zuo Yu came back, he didn't ask for anyone to invite him at all, so he ran over by himself, and prepared all these things for alchemy.

As for some of Xuan Ming's disciples, they had already been preparing to watch the ceremony outside.

"Senior, this time, are we still going to refine Tsukidan?"

"Yes, how many disciples does the sect have?"

"There are a total of fifty sect elders and disciples, but I only have one medicine here, even with the efficiency of my predecessors, I can only refine two pills at most."

This is the current situation on the earth, resources are scarce, and it is too difficult to train a master.

Zuo Yu was not stingy, and took out a large number of elixirs from his space ring, all of which were tens of thousands of years old.

"It's ....... What a rich aura"

"This is a treasure trove of ancient sects, which I emptied, I will start now, I will teach you to refine the pill"

After Zuo Yu finished speaking, he pointed his finger and said, "Fire"

A flame suddenly appeared under the Dan furnace, this kind of flame was just an ordinary earth fire, and it could still be used now, but if you want to refine some high-grade pills, it is obviously not enough.

"Put this spirit grass in first, and after it melts, it will turn into an aura and an elixir
