Mad Dog - Chapter 17: Battle With The Inner Demon

Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

Lin Bei reentered the “Second World” and awakened an SSS-grade talent, the Unlimited Buff.

[Unlimited Buff: SSS-grade. The duration of the buffs that the player has received will not expire.]

With that, Lin Bei embarked on a path of god-sealing.

When he used a health potion, his health would permanently recover by 100 points every second.

When he used the Earth Escape Technique, he permanently gained the effect of Earth Escape.

When he used the Stealth Technique, he permanently gained the ability to stealthily move around.

When he used the Speed Scroll, his speed was permanently increased by 25%.

When he used the Berserk Spell, his critical rate increased by 30%, and his critical damage increased by 100% permanently.

“Hah! With this talent, the world is mine!”

Unable to control his mouth, Lin Jian Yin scared away eight previous girlfriends and six previous managers thanks to his poisonous words. Finally unable to stand it, he goes to a strange antique shop recommended by his friend. The shop supposedly has something that can help him.

Even though a Nintendo that plays cartridges is a bit outdated, and probably no one plays it anymore, isn’t it too exaggerated to place it in an antique shop to sell?

After returning home with a Nintendo, Lin Jian Yin inserts the cartridge that the owner sold to him at a huge discount. Only then does he discover that this is actually a simulation game. The female protagonist isn’t a cute loli, nor is she a mature woman. Rather, with her old lady hair and blue-white slippers, she is such a frightening woman that calling her a Taiwanese babe would seriously be insulting Taiwanese babes.

Gods! His mission is actually to help this woman marry a perfect prince! How is that possible!!!

Wait, as the main guy protagonist, Lin Jian Yin actually isn’t the prince. Then, then, who exactly is he… No, “what” exactly is he?

Imperial soldier Suldak Helansa joined the infantry regiment of the Grand Duke Newman in Bena province, participated in the Warsaw plane war, and rescued a young man in the forest battle. This qualified young man suffered some injuries. Injured, still a mute, Suldak brought him into the barracks, and what we are telling is the story of this young man of unknown origin…
