Tuong Lu Kim has been conquered by Mongolians. They force him to serve Mongolian beef, which smells like Lionel Richie's asshole. Beat up all the Mongolians so they will leave Mr. Kim alone.
After talking to Tuong Lu Kim, you go to the Tower of Peace. Ascend the tower, fighting the Mongolian kids you meet. After battling through the Mongolian kids, you reach the top floor and face the Mongolian horde. After defeating the Mongolian Horde, you rush back down the tower and speak with Mr. Kim to finish the quest. He rewards you with a friend request and a summon item.
