Reborn With The Ultimate Tech Tree

The year is 2050. The sun, a crimson behemoth, engulfed Earth, wiping out humanity's last desperate stand. Chief Scientist Lv Yongchang watched the end, helpless, then awoke in 2030 – a sophomore in college. This wasn't just a second chance; it was a cosmic mandate. A luminous 'Technology Tree' now pulsed in his mind, its branches revealing the blueprints of hyper-advanced civilizations: from controlled nuclear fusion to faster-than-light travel and devastating energy weapons. With only a few short years until humanity's inevitable doom, Lv Yongchang must unleash knowledge centuries ahead of its time, shocking the scientific world. Can one man, guided by the ultimate tech tree, not only save Earth from its fiery fate but propel humanity into an era of interstellar dominance, or will the secrets of the universe prove too vast even for his reborn genius?
