Blood
When he appeared he looked around and felt like he hasn't been here for ages, he felt nostalgic, it might have been six months in the real world but it's been ten years without civilization for him, he could only talk with the system.
After adjusting for a while, he looked at his clone who was sleeping away like a baby, he didn't know what to say to this clone, the clone seemed lazy, the clone also slept a lot when he entered the divine realm for the first time almost six years ago.
He shook his head and cancelled the skill and the clone's memory flowed into his mind.
After looking through the memories a vein bulged on his forehead, he clenched his fist, he felt like summoning the clone and punching it.
It turns out the clone went to the classes that were held, but it did nothing but sleep throughout, it slept and spent some of his point on a lot of food.
His clone was literally on vacation during his absence, he was like a lazy young master.
