The problem is, this thing, is of no use to Gu Yang.
He has conducted simulations for at least hundreds of times, and only once did he pass away of old age, which was when his cultivation level was extremely low.
Now, he could say he has enemies all over the world. If he wants to live until the end of his natural life span, he must be invincible in this world.
If so, he would at least be at the Celestial Being realm, possessing a life span of thousands of years.
By the time his strength reaches that level, whether or not this longevity elixir will still be useful is a question mark.
Gu Yang opened the system, took a look at the remaining balance, and there were only forty-eight energy units left.
After killing Shen Guang just now, he gained twenty energy units.
Shen Guang's remaining glove provided him with ten energy units after recharging.
