Grade E actually didn’t had any special meaning.
It was just one of the responses Su Hao made when he faced an issue. From plan A to plan E, a total of 5 plans. Among them, plan A was the best while plan E was the worst.
Plan A was to confront the Sun family head on if his identity was exposed!
Finding ways to use the advantages which he currently had in his hand; Pharmacist Association, Pianist Association, killer organisation, the identity of man in white, and even Architectural Association, and aid from Chen family to start a war with the Sun family! Although he had little influence, in many ways, he was absolutely not weaker than the Sun family!
It was just that he did not expect Sun Batian to make such a decisive move to eliminate him after knowing his true identity. In some ways, Su Hao and Sun Batian were somewhat similar.
Once they made a move, there would be no mercy.
