Beast Armorer: Infinite Evolution - Chapter 13

When they first met, Tang Wan sighed, “The fifth young master of the Jiang family is just as the rumors said. He’s celibate, aloof, prideful, and is a man to be revered. Unfortunately, he’s so smart that he no longer has any will to live, which made him sickly, and he’s going to die soon…Later on, the fifth young master brought her into his room. When she came out, everyone stared at her in shock.Why was she crying?……Later on, it was said that the fifth young master returned after he recovered from his illness, and he brought a girl back.She appeared pure and harmless, but underneath that harmless appearance, she was actually a spitfire that offended quite a number of people.But the fifth young master just said, “I brought her back, so I’ll let her do whatever she wants. If… anything happens, I’ll take responsibility.”His best friend gave him a reminder. “You’re going to be responsible for someone from the Tang family?”“Since she came back with me, she’s mine. She’s just a young girl and is spoilt. I have to take responsibility.”After Tang Wan married into the Jiang family, she only had one mission. She must give birth to his children before he died!Meanwhile, the fifth young master was puzzled. “You’re a gentle and shy girl during the day, so why are you so different during the night?”Tang Wan thought. ‘I have to make every second count. He won’t be able to live long.’After she gave birth to his son and he became one year old, Tang Wan was prepared to become a widow.However…‘Why isn’t he dead yet?’Much later, the fifth master of the Jiang family asked her, “I heard that you’ve been looking for my death every day. Do you want to kill me by sucking me dry?”

A wicked mother one day brought home a girl. The child was the hidden legitimate daughter of the duke, the heroine of [The Duke’s House Has Three Sons and One Daughter] Loretta. I was Melody, the villainous girl who tormented her and was condemned along with my mother. Not wanting to die like that, I decided to start treating her well now. I personally fed Loretta, put her to bed, and played with her. And then her reaction was…? “I want Melody to marry me!” Caught off guard by her endless affection, I too ended up entering the duke’s family, “I’ll stick right by Miss Melody’s side.” And there, it seems I’ve met a young lord who’s an even bigger ‘Melody fool’? All I did was be kind to survive, but why am I being loved…?!

Chen Sha came to a world of immortal martial arts and was ordered to take charge of the world’s first sect.

Before his death, the previous chief told him:

“If you don’t become the best in the world for one day, you are not allowed to go down the mountain for one day.”

So he closed himself in painstakingly, crossed the heaven gate in his body, and faced off against the ancient and modern powerhouses…

…

Many years later, Chen Sha recalled the day he went down the mountain,

From the moment he descended the mountain, he was number one in the world.

In the next ten epochs, any gods and demons have returned, immortals and Buddhas have lived in the world, ancient powers and ancient gods have appeared one after another.

No matter how the times change, he has always been No. 1 in the world and has never changed.
