I Handed Over the Two-Way Gate and Died Horribly, Then Was Reborn to Rule Both Worlds

[Double Portal] [Demon World] [Modern Technology for Martial Training] [Building Up in Two Worlds] [Decisive and Ruthless] [No Female Lead]

In his previous life, Chu Zhou unexpectedly awakened a double portal. He immediately chose to hand it over to the government, but instead of being rewarded, he was imprisoned and subjected to brutal experiments by the Wang family of the capital.

Before dying, Chu Zhou blew up the research institute, taking his enemies down with him.

When he opened his eyes again, he had returned to the day he called the police.

"Sir, what would you like to hand over?"

Chu Zhou promptly hung up.

This time, he took out loans, stockpiled supplies, traveled overseas to buy weapons, and ventured alone into the Great Qian Dynasty, where demons ran rampant.

The other world was short on food and medicine, making modern supplies worth a fortune.

The modern world had no supernatural powers, while the other world was full of martial arts manuals, demon blood, spirit herbs, and gold.

Others risked near-certain death by consuming demon blood, turning into monsters.

But Chu Zhou founded a biotech company, using modern technology to purify demon blood, analyze martial arts manuals, and quantify cultivation, making all of modern civilization train for him!

He traded gold, developed enhancement serums, established outposts in the other world, and trained an army of martial artists.

While others were still risking their lives for a few drops of demon blood, Chu Zhou had already built a vast power spanning both worlds.

In my previous life, you treated me like a lab rat.

In this life, I will claim the double portal for myself, conquer both worlds, and make every traitor pay for their betrayal in blood!
