The things in the letter were a few photos. These photos were taken of Yu Qian's people sending Wei Zimu's corpse back to China.
It had been a long time since that time. Yu Qian did not expect Jun Shiling's people to discover these things.
Wei Zimu was born and raised in China. He had a deep attachment to China. Later on, he had been following Yu Qian in Continent F. Although Wei Zimu did not say it directly, Wei Zimu had found a cemetery in China when he was alive.
Before Wei Zimu died, he had once said that he did not want to be buried in Continent F. He wanted to return to China. He wanted to be buried in the mountains and rivers, bathe in the sunlight, become a bright star, and look at everything in China forever.
Yu Qian agreed.
Hence, the tomb in the base was only filled with Wei Zimu's clothes and common items. His real corpse had been secretly sent to China.
