A Queens teen yesterday told a jury how he and two pals fatally beat and stabbed an unsuspecting Chinese-food deliveryman as part of a brutal gang initiation.

“Just take the money,” Huang Chen, 18, begged his three attackers as they stomped on his face and torso. But it wasn’t his money they wanted.

That was just a bonus that they divvied up after the killing, Nayquan Miller testified.

Miller – who pleaded guilty to the crime – was a prosecution witness at the murder trial of his fellow Blood and alleged cokiller, William Capeheart, 18.

The attack took place on Feb. 13, 2004, when Miller, Capeheart, and another pal, Charles Bryant, ordered Chinese food from Miller’s usual spot – Ming Garden.They were hungry after a night of smoking pot in Miller’s mother’s Rochdale Village apartment.

Once they placed their order, he said, Bryant mentioned he was looking to move up in the Bloods, to another faction called the Gun Squad.

“He told him when the Chinese man comes, you got to get him,” Miller testified. “You got to do the Chinese man.”

Miller said he thought that meant they were robbing the deliveryman, but when he showed up, Bryant and Capeheart started stomping on him.

First, they attacked him on the seventh-floor hallway. Then, Miller said, Bryant and Capeheart dragged the victim to his apartment.

Once there, the three young men showed Chen no mercy.

They all kicked him in a frenzy, ignoring his pleas to stop. “[Charles] started hitting the guy over the head with [the hammer] . . . with the part that you pull the nail out of the wall with,” Miller recounted.

After pounding on him, they wrapped his body in a garbage bag and put him into a shopping cart. They used the dead teen’s car to drop his body off at a pond in Brookville Park.

Miller had agreed to testify against Capeheart in a plea deal that will send him to prison for 20 years to life.
