After three rounds of experiments, Tu Hunyuan felt that Saine had hollowed him out.
Not physically hollowed out, but mentally.
He was utterly exhausted.
Tu Hunyuan thought that perhaps he should return to the Home Starfield and sleep for a few tens of thousands of years first.
After all, about a third of Tu Hunyuan's life was spent in hibernation. A few tens of thousands of years truly was not that long.
This ability was rather similar to that of Saine's wife, Tourmaline.
Even after advancing to the Dominator Realm, Tourmaline still loved to sleep.
She slept far more than Tu Hunyuan. Afraid that two-thirds of her life had been spent in hibernation.
Even Saine's two youngest sons and daughter slept with their mother whenever they had nothing to do.
Slowly growing stronger and increasing the size of their true bodies through sleep was also one of the Dragon Turtle Clan's abilities.
Saine had named it the Turtle Breathing Technique, and he knew it too.
Three thousand years later, Tu Hunyuan finished the experiments, his face somewhat pale.
He accepted the Earth Element Origin Rule Crystal Saine handed him, then staggered as he prepared to leave.
Saine had wanted to keep the old man a little longer, perhaps exchange a few more words with him.
Having reached Saine's level, he increasingly felt loneliness. As a Level-9 Being, Tu Hunyuan could at least converse with Saine about certain fields.
Otherwise, should Saine go talk to Little White, or to the combined mechanical giant?
People would probably mistake him for having lost his mind.
Faced with Saine's attempt to keep him, Tu Hunyuan left even faster.
This old man was ultimately only a passerby during Saine's final stretch in the Material Star Realm. The chances of them meeting again in the future
