I Have A Dual World Seal

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.
