[Stern forensic security × gentle ancient book painter | Two-way redemption | Strong alliance]
He is Ling Chen, a former forensic doctor and current security elite code-named "Cold Blade". He is accustomed to building the world with rules and evidence. However, due to a cultural relic theft case, he met Su Mo, an ancient book restorer who was looking for the truth in the ink marks.
One is a guardian who was imprisoned by the past and lives as a "weapon without temperature", and the other is a restorer who has a disabled right hand but uses his paintbrush and obsession to fight against fate. When they first met in an abandoned warehouse, the blood on his face and the ink bamboo handkerchief he handed made the two broken souls see each other's loneliness.
From "protecting and being protected" to "fighting side by side", he blocked the fatal knife for him, and he used the fine needle to repair ancient books to fight back for him; he taught him to identify danger, and he taught him to feel the temperature of the world. The coldness of the gunfire eventually protects the gentleness of Mo Xiang; the tenacity of the ink marks also becomes the armor against wind and frost.
This is a story about redemption and growth - you save me from the cage of rules, I protect you from the abyss of darkness, and in the end we all live to be each other's light.
