Fortunately, this was Jiang Chen. His power of perception was extremely strong. Adding that to the memories and knowledge he gained from his previous life, he faced no difficulties at all when trying to understand the Ancient Crimson Heavens Sect's formation techniques. After all, the Ancient Crimson Heavens Sect was strong, but ultimately incomparable to the level in which Jiang Chen had been in in his previous life. The knowledge that Jiang Chen possessed from before still far surpassed that of the Ancient Crimson Heavens Sect.
Therefore, Jiang Chen did not face any trouble when deciphering the Ancient Crimson Heavens Sect's formations. Even if there were occasionally some difficulties, he did not need to meditate much on them. Some slight thinking was enough for him to master the formation entirely. This advantage allowed Jiang Chen to take to formations like a fish to water.
