Marvel: Age Of Sentinels

When an ordinary soul is thrown into a fragile container forged by the power of millions of stars, he faces not only the battlefield of gods and evil beasts, but also the roaring void deep in his heart.
Lynn, an ordinary modern young man, accidentally traveled through time and space and landed in the crisis-ridden Marvel Universe. What came with him was not a system or an old man, but a "gift" heavy enough to tear apart the stars - a cosmic-level energy derived from Robert Reynolds' "Sentinel" template, known as the power of millions of stars.
However, power is not a gift, but a curse. When Lin En came to your land for the first time, his own consciousness was as small as dust compared with the energy that destroyed the world. He is always struggling on the edge of losing control of his energy, and every emotional fluctuation may trigger a catastrophic explosion. What's even more frightening is that the ultimate shadow that coexists with power and originates from light - the whisper of nothingness, echoes in the depths of his consciousness all the time, tempting him to fall into darkness and turn everything into nothingness.
From the dark and damp back alleys of New York to the neon-lit skyscraper rooftops, from SHIELD's secret laboratories to the vast interstellar battlefields. Lin En was forced to embark on a thorny road of survival.
