After traveling to the Tivat continent, Lin Mo became a jar merchant, and since then he has embarked on a journey of selling jars.

Lin Mo: “Let’s open a jar. Whether it’s the Eye of God or the magic weapon, you can buy everything you need. You may earn blood, but I will never lose!”

Ningguang: “As long as you sell unlimited quantities, I am willing to give you all the money, and people can also give it to you!”

Hu Tao: “Golden Emperor Fen Tianyan? Or only ranked fourth on the Yihuo list? I can’t imagine the Yihuo in front of me.”

Ke Qing: “Sword Twenty-Three? Hey, what kind of terrifying swordsmanship is this!”

Yae Godko: “Touch your tail more, can you sell me an extra jar?”

Ayaka Kamari: “How can this Zanpakutō, Xiu Baixue, be so strong!”

…..

A few years later, everyone in the entire Tivat continent was looking for the jar left by Lin Mo.

Carter Williams was your typical twenty year old loser. After a fight in the street leaves him unconscious he wakes up in the body of a young dragon in an entirely new world.

Armed with a system to assist him and two beautiful wives to support him, Carter vows never to live his life hiding in the dark again as he seeks the title of dragon king.

Qin Tian accidentally transmigrated into a sickly body, a body with broken Dantian that was unable to practice Qigong, in another world. Fortunately, God had mercy on him by giving him a level up system. Useless? That was him in the past. Not worrying about practicing Qigong, he was now able to kill Monsters to level up. Easy! Level up when killing Monsters; level up when killing people. An unbeatable sovereign of the clan in the eyes of other people, but in his eyes, he is a glittering big BOSS.
