Curse: Should I Stay in Nuo? Real or Fake?

Time travel + fandom + system + spell Xu Feng, an ordinary modern person, was transported by Universiade and time-traveled into a comic book called The Return of Magic. Xu Feng stood on the ruins with a confused look on his face, and there were several familiar faces standing in front of him. When he came to his senses, he discovered that he was not only bound to the system, but also that he had the ability to control blood - red blood manipulation. Many years later, someone asked: "Teacher, why is the red blood technique ranked among the top three in the imperial family along with the unlimited technique and the ten shadow spells?" Gojo Satoru: "During the Battle of Shinjuku, a super magician relied on this technique and under the guidance of Su Nuo, he activated the red blood technique to protect everyone present." "But what does this prove?" Gojo Satoru smiled: "Everyone present was unscathed." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
