Marvel: the System Does Not Open Until You Are Eighteen Years Old

It has been eighteen years since he came to the Marvel world before Lin Hao's system was activated! "Black Widow, I'm not going to S. H. I. E. L. D.!" "Iron Man, I'm not interested in the Avengers, but for your target poison, how about a deal?" "Thanos, go back to your universe to find stones!" The introduction is incompetent, but the main text is wonderful! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
