Immortal Martial Longevity: From the Start, My Friend's Daughter Was Sent to My Door

[Decisive and ruthless, a scheming old fox, multiple female leads, getting rich across worlds]

Lu Ziyuan is reborn for the third time, with a useless constitution and no spiritual roots.

After struggling for fifty years, he has made no progress in either immortal or martial cultivation.

All he wants is to lie flat and live comfortably as a wealthy idler.

Then his friend's daughter, Su Li, begs him to take her in.

He kindly agrees, but she tries to steal his account books and ruin him!

“Little girl, you think you can outsmart your uncle?”

He sneers and pins her to the bed:

“Either you're mine, or you feed the dogs!”

[Ding! Conquered a fourth-grade constitution. Spiritual roots +2!]

The System suddenly activates!

So all he has to do to grow stronger is conquer high-grade female cultivators!

He sets his sights on the fallen master artificer Liu Ruyan:

“Cultivate with me, and I'll heal your injuries!”

She grits her teeth and lies down. In one night, her constitution transforms into a sixth-grade one!

[Ding! Conquered a sixth-grade Jade Marrow Bone. Spiritual roots +8!]

From then on, he uses one hand to trade trash across worlds:

Mining slag from the cultivation world? It's origin stones in the martial world!

Scrap from the martial world? It's spirit stones in the cultivation world!

With the other hand, he keeps immortal maidens and divine goddesses in check:

The Saintess of Ice Soul Peak saves his life with a single sword strike?

“Saving my life is nothing compared to giving yourself to me!”

In this life, he will cross countless worlds and win the hearts of beauties, forging an imperial path to immortality with a mortal body!
