Pirate: Earning one Trillion before Retirement is not Too much!

In an era of pirate riots, who is the real overlord of the sea?
The four emperors who stand at the top of the pirates?
The powerful Shichibukai?
A revolutionary army with many strong men?
Or the navy that suppresses the sea?
No, not at all. There is only one true overlord in this sea.
“That’s me, Fire Dragon Kahn!”
Kahn’s life creed is: “As long as you pay, I can perform a show of tearing apart the Celestial Dragons!”
Kahn’s original name is Xu En. He has been a pirate for fifty years. With his own efforts, From a private to a vice admiral.
Kahn, who is seventy-two years old, is old and no longer in his peak condition. He is living leisurely in the East China Sea. He has even submitted his retirement application and is ready to rot until the end of his life.
Congratulations to the host for meeting the system opening conditions and the super money system is loaded!
The sound of the system disrupted his plans.
Kahn: “Can I buy life?”
System: “Yes, a portion of the Water of Life can restore the host to its peak state.”
Kahn: “Can I buy immortality?”
System: “Yes, a portion of the Eternal Water , which can completely free the host from the limitations of life.”
“Is there a devil fruit?”
“Yes!”
Kahn was instantly overjoyed.
“Hancock, just wait for me, I’m just old, not dead!”
But then Kahn was stunned.
“How much do these two things cost?”
“The water of life is 20 billion pele, and the water of eternity is 500 billion pele.”
Kahn:? ? ?
Then looking at the oil and water that he had worked hard for for several years, the feeling of satisfaction disappeared in an instant.
In the end, he decided on a goal, to earn 10,000 small goals before considering retirement!
