Rebirth of the Combo Mage

[Rebirth through Time Travel + Traditional Mage + Planar War + Decisive Killing + Spell Combo + Building Power + Kind Master and Filial Piety] Uriel traveled through the plane of rebirth as a wizard, where "the master was kind and the disciple was filial". After a battle of wits, he killed the black-hearted mentor and the world became a better place. He recruited students, built up his power, and used the mountains as towers to advance his territory. From the open sea to the near sea and then to the continent, from the lower planes to the super planes, wherever he was, there were mage towers. For him, who suffered from a lack of firepower, he could only feel at ease living in a group of mage towers. Other people's fireball technique is just one fireball, but Uriel's fireball technique is continuous fireballs and infinite fireballs. You might die if I cast a fireball on you! Spell combos can also combine to form a combination of ordinary thundercloud spells, which are like forbidden spells. Ordinary nourishing spells can be combined to form a sacred nourishing spell, which can last for thousands of years in an instant. With his mage combo, Uriel is not only a master of combat, but also a master among masters in many magic systems such as potions, puppets, alchemy, and magic patterns.
