MTL - King of Industry - Chapter 8 long lost love

Until he became the lowest-ranked master, his lonely and luckless life never changed.Suddenly one day, a descendant injected him with a nanomachine, and the machine started ‘speaking’ to him.[I am the seventh generation Nanomachine manufactured by Sky Cooperation, and I am operating as a central nerve connected to your brain.]“What? What are you talking about?”This was beyond the boy’s knowledge, he turned pale.The Nanomachine linked to his cerebrum realized the User was not understanding a single word it said.“Who are you, and why are you doing this to me?”[“I am the seventh generation Nanomachine.]“Nano Machine?”[Yes, Nanomachine.]The boy’s face hardened.Mashin was the deity the Mashin Religion worshipped, along with the Sacred Fire.The religions’ Master communicated with Mashin.“Um, are you really Mashin?”The boy knelt down and asked with a trembling voice. At this, the Nanomachine attached to his cerebrum realized it had been misunderstood.

Lin Jiufeng transmigrates to become the Yuhua God Dynasty’s Crown Prince but is dethroned, banished to the Cold Palace, and imprisoned there because he had released the holy maiden of their rival country.

Lin Jiufeng isn’t dejected. He has brought a sign-in system with him when he transmigrated and he would receive rewards when he signs in at different places.

Before the Cold Palace’s gates, he signs in and receives the Ultimate Heaven Slashing Sword Skill!

In the Great Council Hall, he signs in and receives the Heaven Patching Technique!

In the Empress Dowager’s palace, he signs in and receives the God of War Totem!

…

Liu Jiufeng imagines that he can quietly sign in like this until he becomes invincible. Yet who would have imagined that the Heavenly Concubine whom he secretly released would rise in rebellion and seize power after she returns to her country?

After she succeeds, her first priority is to attack the Yuhua God Dynasty to rescue Lin Jiufeng.

When Liu Jiufeng hears of this news, he’s puzzled. «Do I need you to rescue me?»

“If he’s being badass, I’m gonna plant my own crops. If he messes with me, he will not live past next year.”

Homebody Zhao Hai brought ‘QQ Farm’ along in his traversal to another world and resided within the body of a fallen noble. His fief was a black land which nothing could be planted, and more importantly, he even had a peerlessly powerful fiancee, who was actually the successor of a duchy and future Grand Duchess!

Even more importantly, he is a magical and martial cripple who could not learn magic and martial arts. His crippling was very thorough.

“I can’t learn magic, but I have the farm. You dare attack me? I’ll release bugs to eat up your rations and crops, and put pesticides and weed agents into your water sources to make your lands grow weeds. See if you dare to attack me. What? You wanna hire killers to assassinate me? Hehehe. I’ll hide inside the little house in my farm and see how you can attack me. When you leave, I’m gonna terminate your country’s crop productions, and then all of your people will revolt. See if you dare to kill me.”

Watch how this somewhat black hearted hobo uses his QQ Farm in the world of swords and magic to become a globally known nightmarish existence.
