After obtaining the book, there is a Dragon Pillar on the left. The Dragon Pillar boss is somewhat difficult in the early game, but easier than the previous Three-Faced Boss (less durable, though it's still recommended to fight it in the mid-game). If you're up for it, give it a try. It is highly recommended to defeat the Chapter 1 boss first, then explore the bottom floor of the Killing Intent Tower to obtain the accessory "Hunyuan Meridian Meter" before challenging this boss, as it significantly increases your margin for error.
Let's take a look at his combat moves below.
Special Mechanic: The "Man in Black with Golden Mask" is a mechanic-based enemy who is invincible in his normal state. You can only reduce his Killing Intent by perfectly parrying or perfectly dodging, followed by attacking during the brief window afterward (fast-attack weapons can land 4-5 hits; stop attacking when you no longer hear the feedback sound from your weapon).
Generally, after you successfully perfect dodge or parry three times in a row, his Killing Intent will be depleted, allowing you to deal damage for a period of time.
After being defeated for the first time, re-entering the area will reveal a save point inside the Dragon Pillar, making it easier to retry the challenge.
Red Light Attack 1: He slides forward while continuously slashing. For the final attack, he jumps, flips, and performs a downward slash with a red light attack.
Red Light Attack 2: A simplified version of the first red light attack. He jumps directly into the air, flips, and performs a downward slash with a red light attack.
Red Light Attack 3: He performs a triple kick in the air, then flashes red to grab you (this move is not very consistent).
Red Light Attack 4: The hardest red light attack to react to. When you see him standing still and then suddenly moving forward, be extra cautious. He may occasionally flash red and instantly dash to grab you, which requires quick reflexes.
Red Light Attack 5: He slashes forward once, then spins around and kicks forward. This kick is a red light attack.
Red Light Attack 6: He sweeps forward twice with his sword, then turns around and thrusts forward with a red light attack.
Blue Light Attack 1: He uses a sword qi attack while standing on the ground, then jumps up and performs several more sword qi attacks. The final downward slash is a blue light attack. This is the easiest move to perfectly parry.
Blue Light Attack 2: Similar to the previous red light attack, he jumps and kicks you several times. However, this time the flip and downward slash is a blue light attack (you must rely on reaction time or judge based on the arc of his downward slash).
