Just when Zhang Yu was training frantically, the team that went to Gaojiazhuang to investigate the situation also came back, and they reported the situation in detail to Cao Yuan, Cao Yuan frowned after hearing it, and hurriedly asked Li Mingqing to invite him to discuss together.

"That's the way it is, we found evidence of the existence of people in the ghost domain, and what Zhang Yifan said may be true. Cao Yuan handed the report to Li Mingqing, and Li Mingqing frowned after taking a look.

"I don't know what the door master has planned?" asked Li Mingqing.

"I'm going to send a team of people to the Ghost Domain to inquire about information, I don't know what Uncle Shi thinks?" Cao Yuan asked after thinking for a moment.

"This is okay, but it must be done in secret, and if the owner thinks it is okay, he can leave this matter to me. Li Mingqing thought for a while and said.

"Since this is the case, then there is Uncle Lao, and if Uncle Lao needs it, he can bring it up. Cao Yuan was overjoyed, he naturally knew how great this uncle's skills were.

"I'll go back and think about this first, it takes a long time to prepare. ”

"How long will it take Uncle Shi?"

"It will take half a year. ”

"That's okay, everything has Uncle Lao. Cao Yuan was silent for a moment, half a year was not a long time, he knew that it was not so easy to cross domains, so he couldn't help but nod in agreement.

"Then I'll go down and prepare. Li Mingqing nodded, saluted slightly, and turned around and left the hall. After he returned to his cave, he thought about it for more than half a month and had an idea in his heart.

At this time, Zhang Yu was still training the Sword Spirit Dance, and he could instantly defeat the cultivators in the Foundation Building Period by using the Sword Spirit Dance, but he was not satisfied, because he was still far from the level of the Sword Demon.

"Zhang Yifan come to see me quickly!" Just as he had just finished training, he suddenly heard Li Mingqing's call, Zhang Yu didn't dare to stay and disappeared in an instant.

Still in Li Mingqing's cave mansion, there was still a pot of fragrant tea on the wooden table, and after handing Zhang Yu a cup of fragrant tea, Li Mingqing asked Zhang Yu about his recent cultivation, and then pointed to the Sword Spirit Dance to answer Zhang Yu's question.

"I see, thank you, Master!" Zhang Yu said respectfully.

"You must practice diligently, okay we talked about other things, I want you to go to the ghost domain, what do you think?" Li Mingqing said as he stroked his beard.

"Ah, ghost domain ......" Zhang Yu was stunned when he heard this.

"As a Heavenly Master, you are the natural enemy of the people of the Ghost Domain, and the reason why I asked you to go to the Ghost Domain is to train you. If it doesn't surprise me, there must be a big move in the formation of a legion in the Ghost Domain, you can go and see their strength to prepare for the future. Li Mingqing looked at Zhang Yu and said.

"Yes, I am willing, but ......" Zhang Yu didn't know what to say, because the Heavenly Master clan had a special way to enter the ghost domain.

"But what? You can say whatever you want. Li Mingqing said seriously.

"That's the case, if you tear the space into the ghost domain, you may be discovered by the people of the ghost domain, especially in this sensitive period, I don't know if there is a way to be a little quieter?" Zhang Yu had an idea in his mind and hurriedly said.

"Oh, this matter?" Li Mingqing frowned, he thought for a while and said: "I really didn't think about this matter, tearing the space into the ghost domain will indeed be discovered, but at the moment this is the only way, is it possible that you have any other good way?"

"Our Heavenly Master clan has a special way to enter the Ghost Domain. Zhang Yu had no choice but to tell the truth.

"I see, originally I wanted you to lead the team, since you have a way, the people on my side will still send it out, and it can be regarded as a cover for you. One light and one dark, no matter where you get information, you can send it back to the maximum extent. Li Mingqing continued.

I have to say that Li Mingqing's idea is good, as long as Zhang Yu goes in, he will not be discovered.

"There's something for you here, maybe you can use it. Li Mingqing thought about it and threw something to Zhang Yu.

"This is?" Zhang Yu took a look, it turned out to be a bronze medal, this bronze plaque was bitten in the mouth by a vicious beast, the inscription on the copper surface flashed, and the seal word was engraved on it: will.

"This is the ghost domain identity token, I got it by chance, and the seal on it says will, indicating that it is the identity of the general. Li Mingqing said.

Zhang Yu took the bronze medal and turned it over and over, carefully put away the token, with this he will have a few more guarantees for his trip this time.

"Okay, if you have any needs, I'll meet you. ”

Since Li Mingqing is so generous, Zhang Yu also cheekily mentioned all the things he needs, although the camouflage mask can disguise the aura of the body, but the yin and yang qi he uses will not change, Li Mingqing thought about this matter and gave him a solution.

Li Mingqing lost a spiritual energy into Zhang Yu's body, this spiritual energy had no effect on his kung fu, the only effect was to make Zhang Yu's yin and yang qi look like yin qi.

Zhang Yu was naturally overjoyed, and the two chatted about the details again, and then Li Mingqing also gave Zhang Yu a lot of information about the ghost domain, and asked him to go back and take a good look before leaving.

Li Mingqing continued to prepare for going to the Ghost Domain, while Zhang Yu continued to practice the Sword Spirit Dance.

It wasn't until half a year later that he was able to easily defeat the Sword Demon Illusion with the Sword Spirit Dance, and his cultivation reached the ninth layer of foundation building with the help of the Meixin Soul Fire, and he was about to enter the Dan Period.

There was no time for Zhang Yu to cultivate quietly, Li Mingqing told Zhang Yu that after ten days, he would officially tear the space and send the team that had entered the ghost domain in. This is a strong team, everyone has a lot of combat experience, and their average cultivation is at the seventh level of foundation building.

With Li Mingqing's consent, Zhang Yu also quietly left the kendo sect, he put on a camouflage mask and became a casual cultivator, all the way to Qiushui Lake.

After he arrived, Xu Lao and the others had already been waiting in Heiyan City, in the past six months, Heiyan City had changed a lot, the defense was more perfect, and countless houses had been built, which was more suitable for people to live in.

When Zhang Yu came to Heiyan City, he saw many children playing in the city, and Xu Lao also told him that a newborn child was born every month, and in a few tens or hundreds of years, maybe the Heavenly Master clan would be able to restore its former glory.

Zhang Yu also wanted to see the prosperity of the Heavenly Master clan, and the ghost domain had to go.

"Are you ready?" asked Zhang Yu.

"You're all set, this way. Xu Lao stroked his beard and said, he walked to the front to lead the way.

There were also Ouyang Mu and Zhou Fat'er accompanying him, originally Ouyang Mu wanted to find a few people to follow Zhang Yu over, but Zhang Yu refused, in his opinion, with a token and a camouflage mask, the Lone Ranger is the best.

The bronze medal was also shown to Xu Lao, and when he saw this bronze medal, Xu Lao also confirmed Li Mingqing's statement, but Xu Lao's words made Zhang Yu fall into deep thought.

"This bronze medal seems to be a ...... left over from the last war" Xu Lao showed Zhang Yu the information prepared by him, these materials are all recorded in the previous ghost domain, there are big cities in the ghost domain, many places are the same as humans, but there are too many races in the ghost domain, such as the three-headed demon dog, the ghost mother, the eight-headed ghost python, etc., they will all transform into human form, and they will become the original state when fighting.

Zhang Yu has read a lot of these materials, which makes Zhang Yu have a little doubt, could it be that Li Mingqing is the person left over from the last war?

None of this is important to Zhang Yu, after reading the information, he recorded all the information in his mind with his ability to remember it with a clear memory.

At this time, someone reported that the formation had been prepared, and Xu Lao took Zhang Yu to the underground spirit vein mine, where a lot of spirit stone veins had been excavated, and those spirit stones were transformed into various materials and turned into a part of Black Flame City.

A huge cavity was exposed, and a complex formation was laid out in the cave.

"This formation is exclusive to our Heavenly Master, it can directly break through the space barrier and teleport to the Ghost Domain, and it must be used by someone from the Heavenly Master Clan, you stand up and input the Yin and Yang Qi into the formation eye, and the coordinates have been adjusted." Elder Xu checked the formation and said.

"If you want to come back, activate this jade slip and we will teleport you back in five minutes. Xu Lao handed Zhang Yu a green jade pendant, and Zhang Yu took it and stuffed it into his pocket and nodded.

Zhang Yu checked the things he was carrying, stood in the middle of the formation in full view of everyone, and entered the yin and yang qi into the formation eye, only to see that the formation was instantly bright, and when the formation was dim, Zhang Yu had disappeared.
