Time passed quickly, and in a blink of an eye, another 100 billion years had passed, and Li Mu's third clone training was successfully completed.

In this experience, a total of 7 clones successfully achieved enlightenment, and the rest all disappeared in the vast history and returned to Li Mu's original body. Li Mu's cultivation level also improved a lot. It is estimated that with another such achievement, Li Mu will be able to be promoted to the third level of Hongmeng Ancestor. It can be said that he has reaped a lot.

However, what made Li Mu a little regretful was the failure of the "system" plan. Those clones that obtained the system did grow rapidly in the beginning, but this was ultimately relying on the blessing of external objects and lacked their own perception. The final result was that none of these clones created their own universe, and their cultivation only stopped at the Immortal Emperor realm and could no longer stagnate, and eventually their lifespans were exhausted and they returned to their original bodies.

Although Li Mu felt a little regretful about this, he did not take it too seriously. After all, this result was within his expectations, and he was just trying it with a trial mentality.

Li Mu also tried to directly grant his clones in the realm of the God of Creation or the Immortal of Creation the branch line of enlightenment, allowing them to attain enlightenment and then sever the cause and effect relationship with them. However, by doing so, not only did his clones fail to attain enlightenment, but it also brought some backlash to himself.

From this, Li Mu concluded that he could only be a bystander in the training of his clone and could not interfere, otherwise it would only backfire.

Shaking his head, Li Mu stopped thinking about it. He had to hurry up and start his next clone training.

………………

In this way, Li Mu tirelessly completed round after round of clone training with 100 billion years as a node. The reason why one node is 100 billion years is because the life of Xiaoxin's universe is 100 billion years. At the same time, this is also the life span limit of the God of Creation or the Immortal Ancestor of Creation. At this point, the cultivator who has not yet achieved enlightenment can only perish with the demise of his own universe as his life span is exhausted.

Time has come to the 10 trillion year, which is an unimaginable time for ordinary people. However, for Li Mu or even any Taoist who has attained enlightenment, 10 trillion years is just a quick passing time and is nothing compared to their endless lifespan.

In these 10 trillion years, Li Mu completed 100 clone trainings, and created more than 10 trillion clones!

By empathizing with the life experiences of these incarnations, Li Mu's experience and character have reached an unimaginable intensity, almost perfect!

After 100 clone trials, more than 1,500 clones successfully achieved enlightenment, thus being cut off from cause and effect by Li Mu, completely gaining independent personalities and becoming truly independent individuals.

And all of Li Mu’s efforts were not in vain, his realm reached the peak of the Hongmeng Ancestor Realm, and he became a Hongmeng Ancestor 9th-level peak realm cultivator comparable to the Tianyi Ancestor!

However, what disappointed Li Mu was that he originally wanted to further his incarnation training, but he found that it had no effect on improving his realm. He even had no idea what the next realm would be.

For this reason, he had to end his retreat.

The figure flashed and disappeared in an instant.

When he appeared again, Li Mu had returned to Earth.

The life experiences of trillions of clones have made his temperament more and more indifferent, and family affection has almost completely disappeared for him.

Li Mu didn't want to become an emotionless machine, so he planned to take some time to spend with his family before he completely lost his emotions, in the hope of regaining his original heart.

Miancheng, Lingxiao Palace, after 10 trillion years of washing away the years, the appearance of Lingxiao Palace still remains the same as before.

At this time, the Earth has become one of the veritable central areas of the Lingxiao Universe, and its range has extended outward countless times. The surrounding areas of cultivators are called the "Earth Domain."

Talking about the naming of the "Earth Domain", there have been some jokes. Some outsiders who did not understand the Earth culture, in order to make it easier to pronounce or for other intentions, actually abbreviated the "Earth Domain" to "Region", and were often beaten by the Earth monks for this.

As the nominal acting master of Lingxiao Palace, Chen Siqi specially issued a decree after learning about this matter, that anyone who insults the Earth Domain will be punished with "Lingqiong 100 Tortures".

…………

When Li Mu arrived at Lingxiao Palace, his father Li Mingxuan and his mother Chen Xiuhua were in seclusion, and he was received by his daughter Li Yunxi.

In the eyes of everyone in Lingxiao Palace, Li Yunxi is an iron-fisted guardian who manages the Lingxiao universe in an orderly manner with his firm and decisive style of action.

However, when facing the father whom she had not seen for 10 trillion years, her eyes turned red, as if all her strength and indifference collapsed at this moment.

He walked forward quickly, his voice trembling and excited: "Father!"

Although Li Mu had gone through countless reincarnations and had long since become indifferent to worldly emotions, his rock-hard emotions began to falter when he faced Li Yunxi. He opened his mouth, not knowing what to say, and finally sighed, "Thank you for your hard work over the years."

Li Yunxi bit her lip. She was not good at expressing her emotions. Her behavior just now was completely instinctive. For a moment, the two of them fell into a brief silence. After a long time, Li Yunxi said, "I... I will go call grandpa and grandma. If they know you are back, they will be very happy!"

"Okay." Li Mu nodded. He was not afraid of disturbing his parents' practice. After all, his parents were already at the 8th level of Hongmeng Immortal Ancestor. The thing they had the most was time. It was a rare opportunity for them to come back. If he had to wait until everyone had free time every time, he didn't know how long it would take for them to get together.

Not long after, Li Mingxuan and Chen Xiuhua hurried to the palace meeting hall. The moment they saw Li Mu, they burst into tears and kept asking Li Mu about his well-being.

Li Mu smiled bitterly and consoled them: "Father, Mother, we are all over 100 billion years old..."

"No matter how old you are, you are still my son!" Chen Xiuhua gave Li Mu a cold look and said angrily.

Li Mu put away his smile upon hearing this and nodded seriously.

Then he said, "I didn't disturb your practice, did I?"

Li Mingxuan waved his hand and said, "We are just bored and this retreat is just to kill time."

…………

Several people sighed again. Suddenly, a white-haired old man rushed in. It was Li Mu’s eldest son, Li Yunqing. When Li Yunqing saw Li Mu, he immediately cried, “Father, you are finally back! Woo woo~”

Li Mu stroked his forehead and wanted to scold Li Yunqing, but in the end he held his words back and patted Li Yunqing's shoulder gently to comfort him.
