Legendary Necromancer: My First Summon is the Undead Dragon - Chapter 3: Small box

In a modern world where cultivators need a place to cultivate or vent their boredom, there are private businesses that set up instance dungeons with the aid of technology and cultivation magic to enable cultivators to train and commoners to experience the life of cultivation. They are called dungeon suppliers.
Xie Jin's one and only dream was to be a dungeon supplier and when his only relative passed away, the relative's inheritance gave him a plot of land and surprisingly, a 'System' Module which the relative had previously used.
With the help of the system, Xie Jin decided to pursue his dream of becoming the number one dungeon supplier.

At the end of a Dynasty filled with Demons and rampant Martial Artists, Lin Xuankong has unfortunately transmigrated to this era, becoming a poor and sickly old man. However, with the help of the system Life Plate, his Talent and Comprehension grow stronger the longer he lives.And his much younger wife is a martial master...“That iron ball used to be Zhang Wu's knife. I squeezed it a couple of times, and it ended up like this! ” said his wife.“I hope you can teach me some Cultivation Techniques. As for the reward...” said Lin eagerly.

One imperial edict and the family’s calculation, the sweet, adorable her met the cold him that was up high. She became his little princess consort. Everyone said that Prince Ying of Western Xuan Empire was shockingly ugly, cold-blooded and ruthless. They laughed at her that she had mistakenly entered the tiger’s den with her life in danger. But she just laughed that everyone in the world couldn’t see the wider picture, and were stupid and ignorant. The ugly appearance was actually beyond gorgeous, cold-blooded was actually gentle and sweet. She only wanted to hide him away and not allow other people to peep at him. “Big Ice Cube, take off your mask and let this princess have a look!” She propped up her chin with saliva flowing down.

“Want to look?” A certain person’s lips hooked into a devilishly charming smile, saying. “Then first, hand over some down payment…” This is the story of a sweet adorable female and a two-faced male’s journey to fight enemies and kill strange things, while pursuing a romantic relationship that was absolutely full of loving spoiling, hilarity and hot-blooded action.
