I Become Stronger by Slaying Demons, and I Become a Saint by Picking up Experience.

Traveling through the troubled times of monsters and demons, he became a rural mortal. Monsters are rampant here, immortals huddle together for warmth, and mortals are bound to die. Monsters attack and the village suffers. In order to save Liu Chen, the mother of the predecessor was willing to sacrifice herself to fill the mouth of the monster. The monster is scornful. "I'll eat your mother, and I'll eat you later. You can't run away, and the whole village can't run away!" Liu Chen was unwilling to give in. "Before I traveled through time, I worked hard all my life but achieved nothing. After traveling through time, will I still have to be a salty fish?" "System? Where is the system?" This bastard is mocking me like this, can you bear it? This woman is so great but she wants to be eaten. How can you bear it? Bite!

"Tell it up for me, thank you!" Liu Chen killed the demon with his own hands, saved the village, and led his mother on the road to becoming an immortal. But he discovered that he couldn't refine his Qi, only his body. "Is the body sanctified? It's interesting." "Let me uncover the fog behind these six realms!" Many years later, Liu Chen punched demons and stepped on immortals, uncovered the mist of the realm, glimpsed the secrets of heaven, and became a saint physically. On this day, Liu Chen stood on the top of Three Thousand Continents, overlooking the bones at his feet, and woke up the system panel in his mind. "I, Liu Chen, have made it this far thanks to my own efforts!" "System! Give me a one-click upgrade to Dzogchen!"
