After Being Expelled, I Decided to Become a God of War!

[High martial arts + no female protagonist + system krypton life + decisive killing + no pressure on strength + non-academic flow] In the world of high martial arts, spiritual energy is revived, alien beasts are rampant, and thousands of races invade. After being expelled from school, Chu Xiu awakens to the Krypton Life System. "Haha, fired?" "It doesn't matter if you can't learn this!" Chu Xiu turned around and went out of the city into the wilderness area to fight with the strange beasts. Bite! Kill the alien beast and bull, and plunder the life span for 10 years! [Ding! Kill the iron-skinned pig and plunder the life span of 15 years! [Ding! Kill the strange beast Green Underworld Wolf and plunder the life span of 20 years! [After spending 50 years of life, the tiger's sharp sword is upgraded to perfection! [After spending 80 years of life, the level of martial arts cultivation has been upgraded to the bone sacrifice level! [After spending 200 years of life, the level of martial arts cultivation is upgraded to the marrow cleansing state! Didn't you expel me from school? Then I will devote my life to practicing martial arts! Others rely on resources for cultivation, but Chu Xiu's growth depends on fate and the fate of strange beasts! The fate of all races! From then on, Chu Xiu's strength increased rapidly. On the day of the college entrance examination, Chu Xiu kicked open the school door and suppressed all the geniuses in the school with one hand: "Is this the level of geniuses in the school? Polish my shoes!" While the so-called geniuses at the Martial Arts University were still complacent about breaking through to the bone sacrificial realm, Chu Xiu had already stepped on the bones of thousands of aliens and overthrown all the races in the world.
