MTL - Cosma Empire - v3 Chapter 743 protection

Lyu Liang was an ordinary young man who was supposed to live a mortal life with his father in a small village. However, a wonderful opportunity led him into the Virtual Land where he learned about his unusual origin and started his dual cultivation journey—to be a Devilish Immortal. There were six races in this world: immortals, humans, devils, demons, ghosts, and spirits. Lyu Liang had access to any of those realms. Whether he would be a great Devilish Immortal was not up to his race, but his will. For him, it was not important to be the most powerful immortal and to be worshiped like God. He eventually chose to live a secluded life with his lover.

In each life, each person will experience their own hardship. Once they obtain happiness, they are furthermore unable to let go. Whether it would be heartfelt love or resenting someone down to the bone, would it matter? As long as that person’s bone has my name, it would be good.

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.

Time travelling from the majestic era after the Recuperation of Reiki, he became Kimura Kazuki, a 16-year-old high school student in Japan, one year before the Reiki Recuperation.

Tentatively, he set out to hone himself to the bone, burning candles at both ends to stockpile resources in preparation for the imminent Recuperation of Reiki. His goal was to be many steps ahead of all humanity when the time comes.

However, it seemed like fate had decided to play a cruel trick on him.

One year later, the Recuperation of Reiki… did not happen as expected.
