After sending everyone away, Li Mu called Bai Ziling and others, explained everything to them, and then took Li Yunxi away from Lingxiao Sect, left Xuantian Continent, and returned to the fairyland.

Li Yunxi's memory will be restored sooner or later, but a too direct method cannot be used, otherwise it will be counterproductive. Only by letting Li Yunxi live in her previous place, experiencing the things she had experienced before, and gradually restoring her memory can her current memory not conflict with her previous memory.

Li Mu arranged everything according to Li Yunxi's previous experience, and after sending enough people to protect him, he returned to Earth alone.

When Li Mu returned to Earth, in fact, only more than a month had passed since he sent his parents and others to Xuantian Continent. It was not because time in Xuantian Continent passed too slowly, but because he did not send his parents and others to the current time in Xuantian Continent, but 1,000 years ago. This was also to avoid the situation where, by the time his parents and others returned, the Earth had changed and all the relatives and friends they knew had died.

The reason why Li Mu returned to Earth was that he received a message from Pangu saying that the remaining cosmic key appeared on Earth, which means that the Chi Emperor had come to Earth. Li Mu and the Chi Emperor were mortal enemies, and his appearance on Earth would certainly not be a good thing. Moreover, Li Mu must get the cosmic key, and the Pangu Universe must not fall into the hands of others.

On Liuyun Island, on the sea, Li Mu called out Pangu.

"Senior, can you feel the exact location of the key?" Li Mu asked Pangu.

Pangu shook his head and smiled bitterly, "The key must have been sealed by the Blazing Emperor. I can sense its aura because I used to be the owner of the key and have a strong connection with it. As for where it is exactly, I don't know. Anyway, it is still on Earth at the moment."

Li Mu nodded, knowing that this matter would definitely not be so simple, after all, the Blazing Emperor's cultivation was not weaker than his. However, he still didn't know what the Blazing Emperor's purpose of suddenly appearing on Earth was.

"Li Mu, is my disciple okay now?" Pangu asked.

“Haha, that girl Zhao Ying has pretty good aptitude. In just thirty years, she has already reached the middle stage of the out-of-body state.” Li Mu said with a smile.

"Haha, that's right. Do you still doubt my judgment?" Pangu looked proud.

"So you really can't recover? If the Pangu Universe is handed over to you again, will it help your recovery?" Li Mu asked.

Pangu shook his head and smiled bitterly, "Li Mu, there are many things you don't understand yet. Once a controller of a universe loses control of the universe, he will no longer be able to control the original universe. If that person is too powerful, he will even be rejected by the universe. This is to protect the current controller of the universe. This is the basic law of the universe. In other words, even if I recover to my original peak strength, this Pangu universe will not be able to accommodate me anymore."

"I understand." Li Mu was also in a heavy mood. After all, Pangu Universe was created by Pangu himself. Now he not only lost control of Pangu Universe, but also faced the risk of being driven out of Pangu Universe. This was too ironic. It was like a child raised by a rich man, who found a new father after the rich man became poor and kicked his biological father out.

"Haha, it's just a small matter. Since I can create the Pangu Universe, I will definitely be able to create another universe when my strength recovers. People like us have the most abundant thing is time." Pangu laughed.

"That's great. If you need any help, just let me know." Li Mu said.

"Well, then you go and do your thing." Pangu said.

After bidding farewell to Pangu, Li Mu was somewhat puzzled. When did the usually high-profile Chi Emperor become so cautious? With Chi Emperor's cultivation, if he really wanted to cause trouble on Earth, no one could stop him, not even Li Mu. Although the difference between their cultivation levels was not big, after all, one was defending and the other was attacking. The Earth did not have a god-level formation to protect it, so it was obviously much more difficult to defend than to attack. However, Chi Emperor still chose to keep a low profile. If it were not for Pangu, Li Mu would not have known that Chi Emperor had come to Earth.

Moreover, the cultivation level of Chi Emperor is similar to his own. Even if Li Mu uses his spiritual sense, he cannot discover Chi Emperor's whereabouts, and will expose himself instead. Chi Emperor is so low-key in his actions, and obviously does not want Li Mu to know his whereabouts.

In view of various reasons, Li Mu decided to keep himself in the dark. Thinking of this, Li Mu used an encrypted phone to call Si Zheng and asked him to use the Earth United Government to pay attention to some suspicious deeds around the world and report to Li Mu at any time. Of course, this matter needs to be kept absolutely confidential, because Li Mu also does not want to put himself in the open to avoid alerting the enemy.

"Haha, I just want to see what you are up to." Li Mu murmured.

Then he decided to find a place to live first. Miancheng Lingxiao Palace would be fine, as it was Li Mu's base camp on Earth. The target would be too conspicuous. Maybe the Chi Emperor had already deployed spies in Miancheng. Kyoto would obviously not work either. After all, Li Mu had lived in Kyoto for quite a long time. As the saying goes, a great man hides in a city. Naturally, Li Mu still had to live in the city, because without using his cultivation, the sources of information in the city were relatively wide, making it more convenient for him to collect the whereabouts of the Chi Emperor.

Finally, Li Mu decided to go to Haidu. In today's society, with the support of big data, Li Mu's use of his bank card is likely to be discovered by the Blazing Emperor, so for the sake of caution, this bank card cannot be used! Li Mu once bought a property in Haidu to investigate Su Qing, but he only lived there for a few days. Now he can use it.

In order to avoid exposing his whereabouts, Li Mu could only try not to use his own cultivation, so he would not use teleportation if possible. Fortunately, when Liuyun Sect left Liuyun Island, they basically did not take any large items with them. Li Mu found a wooden boat, repaired it, and rowed directly to the mainland.

After five days, Li Mu finally arrived at Haidu. Many people on the shore saw Li Mu coming from the sea on a broken wooden boat. They looked at Li Mu with strange eyes and took videos. Li Mu glanced at the broken wooden boat behind him and smiled bitterly. In order to play the Dark Forest game with the Chi Emperor, he hadn't been so embarrassed for a long time. Fortunately, he changed his appearance in advance, otherwise if these people posted the video online, everything he had done would be in vain.
