As an orphan, she was raised by her brother, Su Muqiu. After an unnamed event, they had to survive outside the orphanage. Though they weren't rich, with her brother's talent in gaming, they lived a peaceful life.
Around the time Glory first opened, the siblings met Ye Xiu. As he and Su Muqiu played together, Su Mucheng would watch them fondly. However, her brother died when he was only 18. She would later enter the Alliance with Dancing Rain, the character he originally signed onto Excellent Era with.
Su Mucheng accompanies Ye Xiu to the Excellent Era conference room, where she meets the club manager, her teammates, and Sun Xiang. Mucheng argues against Ye Xiu's contract cancellation to no effect. Mucheng's worst fears become reality when Ye Xiu signs the papers to retire as a condition for his contract cancellation. She accompanies him to the exit. Ye Xiu promises her, “I’ll rest a year and then come back.” Mucheng cries and watches Ye Xiu walk away.
In the 301 Degrees vs. Excellent Era match, Su Mucheng's Dancing Rain duels against Gao Jie's Stellar Sword for the first round of the Individual Challenge. Mucheng ignores Gao Jie's implied insult against her being a girl. Mucheng's Dancing Rain scouts a small area and chooses a high ground to overlook the area. She leaves footprints as a trap for Gao Jie. Mucheng uses Aerial Fire to move and fires an Anti-Tank Missile at Stellar Sword. She fires a (FIM-92) Stinger, a Heat-Seeking Missile, and the Launcher's Ultimate Skill, Satellite Beam, to reduce Stellar Sword's health by one-third.

After a lengthy retreat, Dancing Rain dies to Scene Killer. Mucheng and her teammates lose the Team Challenge. Excellent Era loses to 301 Degrees, 3-7.
Su Mucheng picks up a phone call from Ye Xiu and asks where he is calling from. She learns that Ye Xiu is working on the night shift at the Happy Internet Cafe. She learns that Ye Xiu is leveling up Lord Grim and agrees to help Ye Xiu on the 10th Server. Mucheng's mood improves after hearing from Ye Xiu. She plays Glory in order to support Ye Xiu and not for the fame. Mucheng receives a phone call from her agent. Mucheng tells her agent that she will not attempt to transfer out of Excellent Era. Mucheng puts on a disguise and goes out to a newspaper stand to buy a Glory account card. She is amazed that Ye Xiu notices her under the disguise. Mucheng returns to her room and starts up Glory with her new account. She finds Lord Grim and is shocked to learn someone else is playing on Ye Xiu's account. She chats with Ye Xiu about her account name, Cleansing Mist, which surprised Ye Xiu. Mucheng learns from Ye Xiu that the earlier user of Lord Grim, Tang Rou, possesses great mechanical skill and fast hand speed. Mucheng starts to level her Cleansing Mist account.
Su Mucheng levels quickly. She learns from Ye Xiu, who is leveling up Soft Mist, that Tang Rou does not know much about the professional Glory scene. Hearing for Ye Xiu, Mucheng laughs when Liu Hao lost face the night before when Tang Rou fails to recognize him. At noon, Mucheng's Cleansing Mist levels up to 13. She goes offline for lunch while Ye Xiu goes to sleep. At nighttime, Mucheng levels up with Ye Xiu's Lord Grim in order to speed up Cleansing Mist's progress. Mucheng's Cleansing Mist temporarily joins the guild, Tyrannical Ambition, for the record clear attempt of Frost Forest. In the first attempt, Mucheng acts as the primary player to pull the monsters because Launchers have the longest range in Glory. As MTs and DPSers, Ye Xiu, Tang Rou, and Bao Rongxing take the aggro of the monsters from Mucheng while Crowd Lover deals large AoE damage. Mucheng is the linchpin for the One Wave Push tactic.
Su Mucheng explains to Tang Rou that their level 25 weapons allows the party to output more damage and to reach their full potential. Mucheng executes Delivery Gun with the BBQ skill on the Goblin Patrol Guard. Mucheng is told by Ye Xiu to never use Delivery Gun, which will expose her identity to Crowd Lover and Tyrannical Ambition. The scandal of an Excellent Era player helping Tyranny's main guild would be massive. Mucheng smiles when the party breaks the previous Frost Forest clear record with a time of 13 minutes, 5 seconds, and 47 milliseconds. After leveling with the party, Mucheng logs off to rest.
Su Mucheng is invited by Ye Xiu to join Seven Fields, Sleeping Moon, and Tang Rou's Soft Mist to break Tyrannical Ambition's Boneyard record clear time of 25 minutes, 14 seconds, and 32 milliseconds. Mucheng and the party unexpectedly run into the Hidden Boss, Vampire Knight Logue. Mucheng follows Ye Xiu's order for her to help Tang Rou. Mucheng adjusts her attacking tempo to match Tang Rou before Mucheng takes over the tempo on accident, which annoys Tang Rou. With Ye Xiu salvaging the situation, Mucheng explains that Tang Rou should learn the methods of coordinating with her teammates. Mucheng's Cleansing Mist fires an Anti-Tank Missile to initiate the attack on Vampire Knight Logue.
Su Mucheng watches Tang Rou's Soft Mist get marked for life steal by Vampire Knight Logue's bats. Mucheng and Ye Xiu salvage the situation by fighting the Hidden Boss. Mucheng and Ye Xiu knock the Hidden Boss away to prevent the Hidden Boss from marking a player to life steal from, which is a legendary solution. Cleansing Mist, Lord Grim, and Soft Mist kill Vampire Knight Logue, which rewards a Purple Shield and a Purple Cloak. Due to Tang Rou's insistence, they roll for the Purple Cloak, and Ye Xiu wins. In the next two dungeon runs, Mucheng and the party fail Boneyard to break the record clear time due to mistakes from Seven Fields and Sleeping Moon. On the fourth and final attempt at Boneyard, Mucheng and the party break Tyrannical Ambition's record with a clear time of 23 minutes, 54 seconds, and 71 milliseconds.
Su Mucheng joins Ye Xiu, Tang Rou, Bao Rongxing, and Liu Hao for a Boneyard dungeon run to experiment on Ye Xiu's new strategy. Mucheng initially doubts Ye Xiu's strategy. When she sees Ye Xiu trap one monster in a stone wall's crack with three monster corpses, Mucheng realizes that the saved time adds up. When the party finishes training, Mucheng logs off.
In the first attempt for the Boneyard record clear time, Su Mucheng plays well without any large mistakes. For the Blue Brook Guild, Mucheng and the party set the new Boneyard record clear at 17 minutes, 22 seconds, and 17 milliseconds.
After Excellent Dynasty breaks the last Boneyard record with a time of 16 minutes, 56 seconds, and 78 milliseconds, Mucheng joins Ye Xiu to practice with Huang Shaotian. Mucheng is annoyed by the constant talking from Shaotian, who learns the new Boneyard strategy. After one practice run, Mucheng and the party set the new Boneyard record clear time of 16 minutes, 24 seconds, and 67 milliseconds. When Mucheng walks through the Excellent Era hall, she greets and sarcastically thanks Liu Hao for his help as Hateful Sword. When Liu Hao shouts at her, Mucheng coldly stares down the angry Liu Hao, who retreats. Mucheng walks away.
Su Mucheng goes online to join Ye Xiu for the Desolate Lands record clear attempt.

At 2:00 in the morning, Mucheng tells Ye Xiu not to worry about her time spent leveling her Cleansing Mist account and logs off.
For the second set of attempts at Desolate Lands, Su Mucheng attempts to surprise Ye Xiu by showing up disguised at Happy Internet Cafe. At the front desk, Mucheng sits next to Ye Xiu. Mucheng's Cleansing Mist accepts a level 30 Purple Handcannon from Ye Xiu's Lord Grim.

She is persuaded by Ye Xiu to stay at the Internet cafe for instant noodles.
Su Mucheng eats instant noodles and watches a drama that Chu Yunxiu recommended on half of Ye Xiu's computer screen. While Ye Xiu plays Glory on the other half of the screen, Mucheng tells Ye Xiu that she wants the Light Source Top because the Light Source equipment is pretty. Mucheng fell asleep while Ye Xiu continues to play Glory and watch the drama. When Ye Xiu rates the drama poorly, Mucheng calls him out that he is looking down on Yunxiu's tastes of television dramas. After 7:00 in the morning, Su Mucheng leaves with Ye Xiu to eat breakfast at a restaurant.

In contrast to Tang Rou and Bao Rongxing, Mucheng coordinates well with Ye Xiu and Qiao Yifan to suppress the hidden boss. With the hidden boss at red blood, Mucheng narrowly dodges the Shadow Step copy boss's attacks. When Ye Xiu makes a few mistakes and takes some damage, Mucheng fires an artillery shell near Lord Grim to save Ye Xiu from the hidden boss. Mucheng and the party fight relentlessly and trade damage to kill Illusion Swordmaster Ahong. Mucheng looks at the item drops and sees the Line Canyon Map Piece Three, which is one of the four pieces that necessary for a party to go to a hidden dungeon.

They split up and hide in different buildings to divide the enemy forces.

At 2:00 in the morning, Mucheng helps Ye Xiu set a new Line Canyon record clear time of 29 minutes, 51 seconds, and 44 milliseconds. The time is okay because Mucheng and her party, who have four level 31s and one level 30 character, are below the level 33 ceiling, so the time can be improved at later levels.
