I am already immortal, why should I ascend to become an immortal?

If you eat it, you will become immortal.
I have two bodies, a hundred thousand miles apart.
One that is immortal and indestructible.
One is seriously ill and will not live long.
The first body was named: Golden Cicada.
A drop of blood can make a weak person strong and vigorous; a piece of flesh can extend the life of a dying person for a year.
The other broken body was in the Central Plains, 100,000 miles away.
He was the youngest "king" of the Qin State.
But unfortunately, although "Wang" is young, he is plagued by illness.
But as long as the King of Qin can successfully eat the golden cicada.
By then, an immortal King Qin will lead his cavalry to sweep across the world and unify the country.
