Gon's Harem System - Chapter 54: Ana is the eavesdropper

Young clerk Loya crossed and came to the world of the legendary OP. As a traversal party, he naturally had golden fingers, but his golden fingers turned out to be the dragon annihilator system from the demon tail!

Is still the ice dragon dragon wizard!

What interesting chemical reactions occur when two worlds with completely different power systems touch together?

When the laser of the ape meets the roar of the ice dragon, what will it look like?
When the green pheasant saw the mouth of the dysentery being eaten by a mouthful, what kind of stunned?

“If it wasn’t for fear of becoming a dragon, I would have unified the world!” Said Loya.
“Don’t you dare say that you are seasick?” Carp buttoned his nostrils and smiled dismissively.

- Description from Uukanshu

Lu Zheng possessed a jade seal which allowed him to transmigrate to an alternate world freely.Initially, he thought that the alternate world which he frequented was but an ordinary ancient civilization. With no particular ambition in mind, he planned to become a merchant and enjoyed the casual life of a rich man. He would find a few pretty maidens to accompany him while he explored the place and enjoyed various delicacies. That would be his ordinary and mundane life.His boring life lasted until the day he gave a beggar who showed up at his doorstep a meal. His jade seal obtained a strand of luck because of his action.Since then, he encountered a fox demon visiting him during the day and a beautiful ghost looking for him at night.The members of the Quanzhen Sect paid him tribute while some Buddhist monks stood in his path.So, it turned out that this world was not ordinary.

This stands at the forefront of strategy guides to Life (a shitty video game)!
