MTL - My Stepmother is Soft and Charming - Chapter 557 Complain quietly

In a modern world where cultivators need a place to cultivate or vent their boredom, there are private businesses that set up instance dungeons with the aid of technology and cultivation magic to enable cultivators to train and commoners to experience the life of cultivation. They are called dungeon suppliers.
Xie Jin's one and only dream was to be a dungeon supplier and when his only relative passed away, the relative's inheritance gave him a plot of land and surprisingly, a 'System' Module which the relative had previously used.
With the help of the system, Xie Jin decided to pursue his dream of becoming the number one dungeon supplier.

In the era of pirate riots, who is the real overlord of the sea?

The four emperors standing at the top of the pirates?

The mighty Qiwuhai?

A revolutionary army that emerges from the strong?

Or the navy that suppresses the sea?

No, not at all, there is only one real overlord of this sea.

“That’s me, Fire Dragon Kahn!”

Kahn’s life creed is: “As long as you pay, this old man can perform a hand-splitting dragon man!”

Kahn, formerly known as Xu En, has traveled through pirates for fifty years, and has become a vice admiral from a small soldier with his own efforts.

Kahn, who is already seventy-two years old, is getting old and is no longer in peak condition. He is spending his days leisurely in the East China Sea. He has even submitted his application for retirement, and he is ready to put himself to death until the end of his life.

Congratulations to the host for reaching the system opening conditions, and the super money system is loaded!

The sound of the system interrupted his plan.

Kahn: “Can you buy life?”

System: “Yes, a portion of the water of life can restore the host to its peak state.”

Kahn: “Is it possible to live forever?”

System: “Yes, a portion of Eternal Water can completely free the host from the restriction of life.”

“Are there any devil fruits?”

“have!”

Kahn was instantly overjoyed.

“Hancock, wait for me, I’m just old, not dead!”

But then Kahn was taken aback.

“How much are these two things?”

“The water of life is 20 billion Berries, and the water of eternity is 500 billion Berries.”

Kahn:? ? ?

Then, looking at the oil and water that I had worked hard for several years, the feeling of satisfaction disappeared instantly.

In the end, he decided on a goal, first earning 10,000 small goals before considering retirement!
