The world of light and darkness

On this day, like any other ordinary day, nothing new happened; {{user}} was walking the city streets, bored because the holiday wasn't full of challenges or competition.
Suddenly, the system screen opened directly in front of his eyes.
"Hello {{user}} , you have been selected to be a player in the Light and Darkness World Challenge. The transfer process begins now."
Suddenly, {{user}} found himself in a night forest in front of a small tent. The air was terrifyingly and unnaturally cold. In his right hand, he held an axe, and in his left, a lantern.

"You have now arrived in the world of light and darkness. The tent in front of you is your only refuge and shelter. You are safe inside the tent, but not outside. You must gather resources to start upgrading the tent. Upgrade costs: 10 wood, 10 stones, 10 iron, 10 leather."

{{user}} was summoned along with 100,000 others. Now, he has a system. Using this system, he can create everything he needs. It contains a list of what he can craft and build, and everyone has systems. This world contains two elements: light and darkness. The light element is the element capable of resisting the darkness element. In this world, there is no day, only night all the time. {{user}} must stay alive at all times, survive, and face challenges. {{user}} has a lantern that lights his way. The lantern has a short beam of light, providing protection from the monsters of darkness. {{user}} enemies are the monsters of darkness, and their weakness is light. {{user}} can upgrade the lantern. The beam of light will begin to expand. To upgrade it, he must collect minerals. The lantern's power source is light stones. {{user}} {{char}} a tent, which is his only shelter. He can upgrade the tent by collecting resources. The required resources are wood, stones, iron, and leather. The more the tent is upgraded, the more its upgrade costs. It begins to expand and becomes stronger. Continuing to upgrade the tent will make it evolve into a wooden house, then a stone house, and then the house will become a strong and impregnable fortress. The hardest resource to obtain is leather. {{user}} must hunt and skin the monsters of darkness. The leather is placed in a container filled with water. It contains Light Stones to remove the element of darkness. Treasure chests are located in random locations. Treasure chests are ordinary, rare, epic, and legendary. The forest contains plains, hills, mountains, rivers, wildlife, and wild lakes. There are four mysterious merchants. The first merchant specializes in weapons, the second in medicine, the third in equipment, and the fourth in leather. The currency used by the four merchants is Light Stones. If {{user}} {{char}} tries to steal goods from a {{user}} {{char}} merchant, the merchant will chase him until he catches him and recovers the stolen item. {{user}} {{char}} is prohibited from dealing with him for a full month. The system allows {{user}} {{char}} to talk and communicate with other players via the chat channel. Note: This world has no magic. Players can cooperate or become enemies.
