Ling Chen guarded a monster shop that was on the verge of closing down. The inferior beasts on the shelves had wilted heads and brains. The only three coins in his palm were all his hope for survival. Barton, the owner of the largest animal taming shop in the town, followed him with sarcasm, "A poor apprentice is willing to open a shop?" Just when he was on the verge of despair, a blue light suddenly appeared in his palm - the [Monster Synthesis System] was quietly bound.
When he embedded the down of the grass-leaf rabbit into the groove of the mud shell tortoise shell, the "jade tortoise" with emerald tortoise shell wrapped in snow-white down emerged from the light. The mayor immediately threw out twenty gold coins to buy it. Since then, Ling Chen's life has been completely rewritten: the "Flaming Back Dog" with flame armor, the "Firefly Viper" with poisonous light, the "Thunder Winged Lion" with thunder and lightning... Countless unique synthetic monsters were born from his hands.
Faced with Barton's repeated difficulties and plots, he calmly responded with the help of synthetic monsters; he seized the opportunity of caravan cooperation and sold synthetic monsters to all parts of the mainland; he was invited by the Duke of the Empire to settle in the capital, and became a sought-after target of the royal family. From a small corner shop to chain stores all over the mainland, from being penniless to being as rich as a country, Ling Chen used the system to synthesize not only monsters, but also his own legendary life.
