Su Chen traveled to the world of beast control and activated the god-level synthesis system. Two low-level beast pets can be unconditionally synthesized into high-level beast pets. The higher the quality of the beast pet, the stronger the awakened beast control skills will be! "Ninth-level abyss dragon + ninth-level purgatory viper = abyss demon dragon god level!" "Ninth-level Demonic Butterfly + Ninth-level Devil's Eye = Godly Butterfly of Hell!" "Ninth-level undead angel + ninth-level holy angel = sixteen-winged demon angel god level!" "..." Synthesize the Immortal Divine Phoenix at the beginning, and awaken the SSS-level beast-controlling skills to become immortal! While others were still fighting for a low-level beast, Su Chen had already contracted with the Immortal Phoenix, the Abyss Dragon, the Hell Butterfly, the Sixteen-Winged Demon Angel... I synthesize it! I evolve! I am invincible! PS: The invincible flow of beast-controlling is a cool article, it overthrows everything, the introduction is weak, please read the text!
