Let me laugh

Jiang Changsheng was reincarnated as the crown prince of the Jing Kingdom. However, he was switched at birth and was sent to grow up in a temple. He was raised as a Taoist.
The change in his fate was devastating. Fortunately, he was able to awaken the Survival System and gained the power to not die from aging. Every time he survived a dangerous event, he could receive rewards.
His senior brother almost killed him by accident. He was lucky enough to survive that and was rewarded with the Divine Shadow Kick.
He almost got crushed when the ceiling fell on top of him during an earthquake. He was able to obtain the Nine Seeking Divine Dragon Step.
After surviving the demon invasion, he was rewarded with the magic treasure, Demon Subduing Mace.
This was a world where kingdoms stood tall, demons rampaged in the wild, martial arts ruled the street, and where Gods did not exist.
300 years had passed.
The Jing Kingdom was starting to fall. The dukes came together and made the emperor their puppet. The kingdom was divided. After decades of internal conflicts, the kingdom was on the verge of being invaded. The citizens were pretty much living in hell.
The puppet king, Jiang Xuanzhen, arrived at the temple and begged, “Ancestor, I apologize for being weak! Please! Help us regain our glory!”

My Descendant Begged Me To Help Him Just After I Became A God

Jiang Shan's consciousness slowly awakened. He opened his eyes and the white light in his vision disappeared, replaced by endless darkness.

He saw his grandfather flying with him. However, the darkness in this area was boundless and there was not even a gust of wind. Therefore, he did not notice that they were flying.

Jiang Shan subconsciously asked. In a daze, he realized that there were no enemies around them and their location had changed.

Jiang Changsheng looked ahead and said, "I guess so."

When Jiang Shan heard that and recalled Jiang Changsheng's previous words, he could not help but tremble in fear. He carefully asked, "Grandfather, could it be that you have…"

"That's right. The Dark Netherworld and that Blood Realm Ancestor no longer exist. This is the Dark Netherworld, after transforming into nothingness."
