No, you can only accept it if you call Dong Zhuo. You need to use a seven-star knife in battle. Cheng has a red place in Luoyang's residence. You can find the key by inserting it into the cave next door to Luoyang. By the way, even if you accept this boy Lu Bu, he will defect if you hit Yuan Shu. And after Yuan Shu died, he followed Yuan Shaogan. The only advantage of accepting him is that he told you the location of the red rabbit. I forgot how much it costs to go west for 8 squares and south for 1 square near the water dungeon. In a word, if you are looking, you will find a "big casino" called Red Rabbit.
