Soul Travels to Another World: I Rely on Killing at Second Sight to Keep Leveling Up

[Soul Penetration] [System] [Upgrade Flow] Qi Yun is an ordinary college student who has been staying at home after graduation. Until one night, he was illuminated by a white light falling from the sky, and woke up to find that he had traveled to a fantasy world of swords and magic. Like most time travellers, he also acquired his own system. However, after seeing the system prompt, my heart suddenly went cold. [Welcome to the continent of Ezemite, the following abilities are randomly selected for you, and are being drawn...] [Extraction completed. Your ability is [Kill at Second Sight]. The specific effect is as follows: When fighting an enemy for the second time, you will be able to kill the opponent with one hit and be completely immune to the opponent's attacks. Although this skill looks pretty good, Qi Yun knows in his heart that with his current ability, he can't even defeat the gangsters on the street, let alone conquer the vicious monsters. But unexpectedly, Qi Yun accidentally used a skill to kill a goblin by chance, and finally discovered the terrifying nature of this skill. One hit to kill? Isn't that an instant kill? That is, as long as I can get through it once... In this way, Qi Yun began his journey of fighting monsters and upgrading in a different world.
