Everyone Trains in Martial Arts, and I Slay Enemies on the Battlefield to Become a God

【High Martial】【Ruthless and Decisive】【System】【War】【No Heroine】【Epic Worldbuilding】 Shen Tianjie transmigrates to an Earth where martial arts reign supreme and ferocious beasts run rampant. Fortunately, he awakens the Longevity System. All he has to do is kill a ferocious beast to gain its remaining essence. By spending essence, he can endlessly deduce martial arts techniques and accelerate his cultivation. The strongest known cultivation method is top-tier Heaven rank? I’ll deduce a God rank method instead! It takes years to master a martial technique? I’ll deduce it straight to perfection in just three seconds! Sometimes, Shen Tianjie wonders why he seems to have more and more essence the more he uses. With his spear in hand, he looks up. They say the bronze ancient sword that pierced the sun contains many powerful ferocious beasts. They have lived for ages, taken human form, and call themselves the Divine Sect, lording it over all. “I have crossed the void to come here, solely to borrow a little of your lifespan and prove my path to immortality!”
