Soul with You

On the day when Wei Ying was found, the doctor once said: "Young Master Wei exploded the golden core. With the power of the explosion, he instantly urged a large amount of spiritual power to form a body barrier. Therefore, Young Master Wei survived from the rolling river, but was barely injured. The golden core was broken like dust and dispersed into the spiritual veins, he can never build the core in the future. Ordinary cultivators will never take such decisive methods. Young Master Wei's will of survive, his determination on the spot, and his ability to endure pain are truly different from ordinary people, and it is admirable."
Lan Wangji knew what the golden core meant to Wei Wuxian. ...
Wei Ying gave up the golden core and used such a painful and tragic way in exchange for the greatest possible survival and returned to him. ...
Wei Ying believed that he would find him in time. ...
Even Wei Ying believed that he could help him repair the golden core. ...
However, if he failed to find him within seven days, or failed to think of the method of repair the core, this golden core could not be formed. ...
How can the golden core be the same important as you(Lan Wangji)?
