Upon returning to Beijing, the three went their separate ways for the time being. Zhang Heng was pretty lucky—there had been no roll call on that one day he missed class, and once he arrived at the campus, he headed straight for the showers.
It was around three in the afternoon, so the public bath was barely occupied. Zhang Heng stood under the shower, letting the water wash away the residual black blood on his body. Though his body had recovered, it was still better to be safe than sorry since the blood belonged to one of the four horsemen.
Zhang Heng lathered himself up with a grand amount of soap, then rinsed himself with warm water. He repeated the whole process twice for good measure.
He looked at his right arm—the needle mark had disappeared, only less than five hours since he pulled it out.
