Spell: Look Out! This Is Called Red Blood Exercise!

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. When he opened his eyes again, Xu Feng found that he was already in Shibuya Station wrapped in curtains. 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.
