I don’t know the length of Hydra, or the depth of S.H.I.E.L.D.

I don’t know that Ant-Man has an outfit, and I don’t know that the Winter Soldier has an iron fist.

I don’t know that there is chaos in the Bliss Space, and I don’t know that Miss Xiaoyu wants to get married.

I don’t know if the walking corpse is cheating, I don’t know whose fault the alien is.

I don’t know the legend of mutants, I don’t know that Kryptonians can’t afford to provoke them.

I don’t know that Black Panther’s family has a mine, and I don’t know that Iron Man is a mess.

I don’t know what happened to Lei Shen’s family, and I don’t know that Thanos is thinking about making troubles.

He doesn’t know the past or the way forward, he only knows that he stands firm at the critical moment and cannot be cowardly.
