Han Fei was really grateful for the 100,000-year competition in the East Sea Divine Realm. It had broadened his horizons, given him a lot of insights, and provided him with a lot of resources.
It turned out that in addition to the river of time, there was really a river of life in this world. Although he didn't know the river of life at the moment, he could already see his own river of life.
The water in the River of Life represented his vitality, and the length of the River of Life represented his lifespan. His vitality could be replenished, but his lifespan couldn't be easily extended.
Once this river of life burst, it meant the loss of life. It meant that even if he had vitality, he couldn't repair his lifespan.
"So this is the true relationship between lifespan and vitality."
