Others Suck Blood to Restore Their Blood Volume, but I Suck Blood to Increase the Upper Limit!

The abyss invades, the world is digitized, and the era of job transfer for all begins. Li Feng traveled through time and awakened the berserker profession. All skills consume blood and is called the most useless profession. No one knows that Li Feng, a time traveler, has his own golden finger. [Blood-stealing increases the upper limit of blood volume: All the blood-sucking effects attached to any of your attacks are used to increase the upper limit of blood volume. The berserker's attack skills consume a certain proportion of blood and cause damage equal to the blood. Aren't I invincible? Your normal attack causes 10 points of damage to the demonized pheasant, 10% of the blood-sucking is completed, and your upper limit of blood volume increases by one. Your skill is a critical strike, causing 10,000 points of damage to the Ice Demon Wolf, 18% of the blood-sucking is completed, and your upper limit of blood volume is increased by 1,800 points. Your skill Bloodthirsty Continuous Slash caused 23 million points of damage to the Abyss Demon General, 29% of the blood-sucking was completed, and your upper limit of blood volume increased by 6.67 Million points. The devil descended and struck a devastating blow. When everyone was desperate, Li Feng stood up. The attack fell on him, knocking off less than one billionth of his health, but the demon was dead. "Sorry, my blood volume is too high, so I never add armor. The more blood you take away from me, the more damage you will get back. If you die, it only means that you are too weak." "Which other demon is coming? Hurry, don't waste time." The devil is confused! Humanity cheers! Only when he woke up, he abandoned his ex-girlfriend and his adoptive parents, and he was completely stupid.
