Traveling Back to the Barbaric Era, Starting from Scratch

Qin Lan was shopping that day when suddenly a beam of light covered his whole body. Qin Lan looked around and saw that there were many people covered by the beam of light falling from the sky just like him. Suddenly Qin Lan found that his beam of light was a little different from others. There was an electric current similar to a code in the beam of light. Before he could take a closer look, he suddenly felt dizzy. When Qin Lan opened his eyes, he found that he was on an island of only more than 100 square meters. The key was that it was still an empty island. Qin Lan lay down and looked under the empty island, but he could only see a layer of fog. Suddenly a voice appeared in Qin Lan's mind, (Welcome to all wilderness survivors, take a look at what's around you. You will live on this empty island for a while in the next few days. Don't die. There will be surprises in the evening. Collect what you need and try to survive, hehe) If you listen carefully, there is no sound anymore...
