Shen Du has been able to see things that others cannot see since he was a child.
Gray shadows, residual consciousness, squatting in the corner, floating on the ceiling, squeezing in through the cracks in the door at night - he has been numb after looking at them for twenty-one years.
Until he picked up a bronze mirror at an archaeological site.
It was raining the day the mirror was unearthed. His blood dripped on the mirror, and a fleeting blue light showed under the rust layer.
That night, all the gray shadows were gathering in the direction of the mirror.
Then a man crawled out of the mirror.
Silver armor, disheveled hair, eyes like two bottomless wells.
"General of the Left Guard of Dajing, Pei Zhao."
Shen Du said expressionlessly: "I've never heard of this dynasty."
——
Pei Zhao was sealed in the breast mirror for four hundred years.
When I came out, I found that the dynasty was gone, the old friends were gone, and even the wall could hardly hold on.
Only a young man with a cold face was left, sleeping with the mirror next to his pillow.
"Don't die," he said.
"None of your business." Shen Du replied.
——
Later, Shen Du learned to use fragments to raise the mirror, use blood to summon him, and use essence to bring him out to fight.
He made a trade with his life.
The day Pei Zhao escaped from the mirror, the sun shone on two people - one with a shadow and one without.
Shen Du stretched out his hand and passed his fingers through his translucent palm.
Pei Zhao turned over his hand and held him.
Intention: Those who help others also help themselves, and those who are saved also help others.
