In 2017, Marvel partnered with the Chinese media company NetEase as part of an initiative to expand its audience in China and East Asia.

This partnership resulted in the creation of the superheroes Lin Lie and Aero, both of whom debuted in May 2018 in Chinese-language digital manhua published on 163.com.

In 2022, Lin Lie made his debut as Iron Fist in a five issue miniseries written by Alyssa Wong and illustrated by Michael YG and Sean Chen.

[7] In May 2023, to celebrate Asian American and Pacific Islander Heritage Month, Lin starred in a backup story in Daredevil Vol.

[8][9] In August 2024, Lin was featured in a one-shot commemorating the 50th anniversary of Iron Fist, with Wong returning as writer and Ron Randal illustrating.

One year after his family's disappearance, Lie is attacked by a demon at his apartment after receiving a mysterious red orb contained in a puzzle box.

Lie gives chase but is attacked by Baron Mordo, who attempts to take the Sword for himself, but is driven away by Doctor Strange.

[11] Now going by the name Sword Master, Lie begins a superhero career while fighting the forces of Chiyou and searching for his missing family.

During the "War of the Realms", Sword Master and several other Asian superheroes are summoned by Brawn's teleporter to Seoul to help the New Agents of Atlas defend Asia from Queen Sindr and her Fire Goblin forces from Muspelheim.

[15] Naka reveals that Ismenios attempted to plunder Atlantis's treasure hoard during the absence of its sea serpent guardian, but was caught by Namor.

[19] During the "King in Black" event, Sword Master initially defends Shanghai from invading symbiote dragons with Aero and the Black Knight, who had been abandoned in Shanghai and separated from his Ebony Blade, but abandons his mission after realizing that the symbiotes were minions of Knull rather than Chiyou, believing the task to be beneath him.

Due to the Sword of Fu Xi's destruction, the seals on Chiyou's three tombs further weakened, prompting more of his demon minions to attack cities around the world.

During his hunt for the shards, Lin Lie briefly encounters his predecessor Danny Rand, who had previously given up the Iron Fist, in Flushing and helps him fight off several minions of Chiyou.

Due to the shards of the Sword of Fu Xi embedded in his hands, Lie cannot summon the Iron Fist consistently and is left in a constant state of pain, which makes him a target of ridicule and scorn by several detractors, including his rival Yang Yi.

Lie takes a portal to the second tomb with Min and Yi but after arriving they encounter Fat Cobra and the Bride of Nine Spiders.

Severely outmatched and running out of time, Lie flees from the fight to the Nü-wa Clan's headquarters, but is too late to prevent its destruction from Feng and Chiyou's minions.

[26] During the "Judgement Day" storyline, Lie takes a flight to Seoul to rendezvous with White Fox but is visited midflight by Loki, who reveals that he is in league with Feng.

During Loki's judgement, Lie rescues him from being pinned down by a vision of Mjolnir by using the aura from the Sword of Fu Xi to lift it.

[27] Following Danny's advice, Lie seeks out Daredevil in Hell's Kitchen to teach him how to fight while mitigating the chronic pain in his arms.

Unbeknownst to both, the Shocker was hired by the Ch'i-Lin to keep Lie and Pei preoccupied while it possessed Razor Fist into attacking Danny at his apartment.

When activated, the Sword generates mystical green flames, which can be launched as projectiles or be used to increase the cutting power and range of the blade.

[23] Due to the broken shards of the Sword of Fu Xi embedded in the flesh of his hands, Lin Lie suffers from chronic pain.

[39] Due to his training under the Nü-wa Clan, Agents of Atlas and the monks of K'un-Lun, Lin Lie is an expert swordsman, martial artist and acrobat.
