Create assassins from bugs? My Zerg legion strikes unseen.

Transported to a martial arts world, Gu Changge took over a clinic that pretended to heal the sick but secretly ran an underground assassin guild. His assassins were nearly wiped out, and rival shops kept harassing him. Cornered by misfortune, the Zerg Creation System awakened unexpectedly! By combining insects, rare materials and blood essence, he can craft powerful monsters fit for combat and stealth assassination, which can even switch forms freely. He breeds Zerg creatures like Shadow Spiders and builds a private assassination unit. Taking high-reward bounties, his elusive Zerg forces help him gain a firm foothold across the martial realm, striking terror into all foes.
