In the Cross religion, God is the only one, and all miracles are in the hands of the one and only God;

The “right side” of God, in the Cross religion, means “equal to God”;

The ‘Demon God’ in the forbidden, the ‘beast’ in FATE, the ‘Gods of the gods’ of the godslayer, the ‘Witch Cult’ from zero, the ‘Final Trial of Humanity’ in Hakoniwa…

This is a story of transmigrating into the son of Aleister Crowley, the ‘world’s most evil man’, waving his right hand, and ascending to the God of Crusades.

“The magic name ‘BEAST’ 777 means ‘I will overcome the evil of mankind’!”

Xia Wen transmigrated to the world of One Piece and awakened the [Multiverse Jar System].

He can get the same thing as long as he sells a jar.

Furthermore, selling a certain quantity will also grant you exclusive jars and other benefits such as shop owner privileges.

When Shirahoshi encountered the shrinking lamp, she shrunk to a normal human size. When Shanks ate a Senzu Bean, he grew a new arm.

When Akainu drew his Ryuuka sword, Jakka, it ignited the sea. When Crocodile sat atop the Creation Engine, contemplating the future.

When Luffy opened the One Piece manga, he learned about the future developments.

Everyone was suddenly awakened to find that the sea had become completely unfamiliar!

Navy Headquarters: All Rear Admirals and above, get the chance to open cans!

The four emperors temporarily put aside their grudges and reached a consensus: let's get our hands on the jar first!

The Five Elders held an emergency meeting: We must stop Xia Wen from selling the cans! We must maintain world stability!

When Im awoke from his slumber and learned that there were several Nika Devil Fruit users in the ocean, he felt as if the sky had fallen!

The strongmen who emerged from the jar shop all headed towards the sea, solely to spread the word about the jar shop's greatness.

Thus, a new legend was born on the high seas: "Better to offend the Four Emperors than the Jar Merchant!"

Now... it's the era of big can opening!
