After all, for a cultivator in the Foundation Establishment stage, top-grade spirit stones are indeed too precious. If a cultivator in the Golden Core stage knew that Wu Hao had a top-grade spirit stone, even if there was only one, he would probably not be able to resist coming to snatch it.

This is obviously not a good thing for Wu Hao, who wants to develop in a low-key manner.

Of course, Wu Hao now not only has 100 million top-grade spirit stones, but also the resources left behind by Su Qiaoran when she left, so he handed them over to his son without hesitation.

[Ding, congratulations to the host for sending out ten Foundation Establishment Pills. Ten thousand Foundation Establishment Pills have been obtained.]

[Ding, congratulations to the host for sending out five Jindan Pills. You have now received five thousand Jindan Pills.]

[Ding, congratulations to the host for sending...]

Before long, the resources left by Su Qiaoran increased a thousand times in Wu Hao's hands. Unfortunately, the system would only feedback things of the same level. In other words, sending out a Heaven-level technique would only feedback a Heaven-level technique of the same level, and it would be the original one.

But even so, the current resources are enough for Wu Rulong to cultivate and become an immortal. By the time Wu Rulong becomes an immortal, I'm afraid I will be able to break through to a realm above immortals.

Looking at the resources in the system space, Wu Hao nodded with satisfaction, then looked at Wu Rulong and said seriously.

"Okay, go practice and strive to break through to the Foundation Establishment Stage as soon as possible."

"Yes, father!"

Soon, time passed quietly. Three years, or even less than three years, in just one year, Wu Rulong successfully broke through to the foundation-building stage.

And Wu Hao successfully advanced to the Spirit Sea Realm amidst the terrifying feedback.

When Wu Rulong was fifteen years old, he successfully broke through to the Linghai realm, and Wu Hao also broke through to the Jindan stage.

By the time Wu Rulong was eighteen years old, he had successfully broken through to the peak of the Spirit Sea, while Wu Hao had already reached the late stage of the Golden Core.

"Tsk tsk tsk, it seems that relying solely on my son's cultivation to provide me with feedback is still too little. If this continues, when will he be able to break through to the Great Emperor level?"

Wu Hao thought to himself that he was now in the late Jindan stage and his lifespan had reached a terrifying one thousand years.

Cultivating immortals is itself a matter of going against the will of heaven. Every time one succeeds in going against the will of heaven, one can obtain great benefits, which naturally includes the increase of lifespan.

The foundation-building stage can reach two hundred years of age, the Spirit Sea stage can reach five hundred years of age, the Golden Core stage can reach one thousand years of age, the Nascent Soul stage can reach three thousand years of age, and the Spirit Transformation stage can reach ten thousand years of age.

It takes 30,000 years to refine the void, 100,000 years to overcome the tribulation, 200,000 years to become a saint, 500,000 years to become a supreme being, 600,000 years to become a quasi-emperor, and 1 million years to become a great emperor.

But for Wu Hao now, the speed of his realm improvement is still too slow. It seems that it is time for Rulong to get married and have children. Thinking of this, Wu Hao couldn't help but look at Wu Rulong who was meditating and practicing.

But Wu Rulong shuddered and felt a little curious.

"Strange, why am I still sneezing? Could it be that Mom misses me?"
