National Icefield Survival: I Will Become Stronger When I Sign In

The whole people traveled to a different world, and order, law and morality completely collapsed! Lu Yuan, a good young man, came to this world and encountered an unknown strange creature at the beginning? Hold on, don't wave! Grab your lamp strap, read the manual, craft your weapons, and get ready for the nightmare! Fortunately, I got the essential artifact system for time travellers! On the first day I signed in, I got an engineer shovel and tactical equipment! After collecting supplies and returning home, the door was almost breached and the shelter was rendered useless. The sky is darkening, and the weirdness will tear you apart! It's dawn, remember to bring an oil lamp when you go out, and be careful of other humans! While everyone else was trembling, Lu Yuan had already passed the sign-in system and obtained top-notch equipment and a dog. Bite! Congratulations to the host for successfully signing in...] One person and one dog face the danger hidden in the darkness and try to survive.
