Survival: From the Start, It's a Fight to the Death in the Secret Realm

Fantasy concept + System + cultivation + immortality cultivation + multiple female love interests + revenge + pursuit + leveling up + play the pig to eat the tiger + decisive killing.

The Host transmigrates and is reborn in a secret realm in the cultivation world, activates a System, and gains its help to increase their strength and turn the secret realm upside down.

Along the way, they slay demon beasts and kill cultivators to avenge the original body's owner.

They disguise their strength and play the pig to eat the tiger, killing opponents above their level and running rampant through the secret realm as easily as chopping wood and slicing vegetables.

They fight for resources and treasures, kill cultivators, and obtain the secret realm's legacy, rapidly increasing their strength.

After leaving the secret realm, they are hunted by the six major sects and spend their days fleeing and hiding.

After finding an opportunity, they increase their strength, turn around and crush the six major sects, and establish a sect of their own.
