Attribute restraint? Sorry, I am a full magician

Time Lord Tan Xiao returns to the day when Blue Star undergoes great changes.
With the memory of the future and the heart of arcane magic, he can activate the talent trees of all magicians.
Having obtained the Arcane Heart in his previous life, he was already a mid-level Arcana Supreme, so that the Arcane Heart could only be upgraded to less than two hundred levels. But even so, he still stood at the top of the magician profession, and He became the only one among the magicians who had touched the ultimate secret.
This is why he can return and have the opportunity to change the catastrophe in the future...
