Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

Pei Jiu picked up a girl by the riverside. He settled her on the mountain, and planned to send her back once she recovered. This delicate girl was a useless crybaby, so Pei Jiu had to be a nice person. He cooked her food and washed her clothes. He let the troublesome girl ride on his shoulders so she could pick fruits. During winter, he would warm up the bed for her. One day, she hugged Pei Jiu’s arm with a smile. “Big Brother Pei, you’re really an honest and a good man. I will marry you and give birth to your babies!”

Pei Jiu eyed her critically and scathingly enumerated her shortcomings. She was ignorant and spoiled. She only knew how to pester and flirt with people all day long. Give birth to babies? Go ahead, give birth to caterpillars.

The delicate girl bawled so hard that she passed out. The next day, Pei Jiu returned to his mansion and told his servants to prepare for his wedding ceremony. When he returned to the mountain in the evening, Pei Jiu opened the door as usual, but he found that the cheeky girl had disappeared. He searched the whole mountain for her to no avail. No one would act like a spoiled brat in front of him anymore. What a headache.
