After Guarding Tianguan for a Thousand Years, I Am the Only One Left in the Clan.

After Xia Zhenbian traveled through time, he found that he was the only one left in the gatekeeper clan. At the same time, his predecessor was also the most dazzling genius of the Shouguan clan. When Xia Zhenbian decided to continue to hold on to the city, the upgrade system appeared. "What? Lots of monsters?" "I'm not afraid. I have mirror image and split attacks. It's no exaggeration to say that I can definitely clean up a whole area with one shot." "Why is the opponent's master too strong?" "It doesn't matter. Let's learn about Wind Step. He is invisible and doubles his attack. As long as he is not several times stronger than me, I can handle him." "Why is there a celestial being on the other side?" "I'm sorry, I am invincible below heaven and earth. Even if you wait for two days for me above heaven and earth, I will be invincible." This is the story of a young man who uses the upgrade system to guard Tianguan alone. This novel and its characters are purely fictitious.
