Doomsday: Infinite Upgrades with My Little Sister

The wooden door of the shelter can be upgraded to a mechanism pulley stone door or a security mechanism stone door passage with a camera and a guard room shooting port can be added inside the wooden door. Branches can also be placed at the door of the wooden door to block the iron hardwood door. You can also make a furnace workbench in the shelter warehouse to recycle materials. Experts can dismantle firearms and get firearm blueprints to make cold soldier weapons, armor, metal ingots and other materials for upgrading. The vehicle can be equipped with a flip-top crossbow with a lock, and a plastic shell can be added to upgrade it to an electric tricycle. Otherwise, what will happen if the weather is bad. You can also upgrade it with hard iron wood and iron ingots to make a huge boomerang as tall as a person, which will definitely hit the huge boomerang (it will bounce back when it hits the enemy with unlimited firepower). If you have plant seeds, you can use upgraded iron armor to recruit troops to develop farm cooperatives and evolved knight bastions. Develop five evolutionary knights in the surrounding 4 weeks, and establish a peripheral defense line with crossbows (which can be loaded with shotguns and are effective in melee group attacks) and catapult turrets. Stone passages are used to connect the farms. The farms are in the inner safe zone. The refuge is entered from the guarded safe passage in the core prohibited zone. A peak fire sentry tower is set up on the outermost border to guard.

It's pretty good, but it felt a bit too grinding when killing Wu Er. Fang Zhou felt that he didn't have to die and could be taught some fighting skills. Other aspects were pretty good. Here are some suggestions: 1. For other developments, you can use a knife or other things to dig out a larger shelter space. 2. The ground can be strengthened with cement or something because there are monsters underground. 3. The door should also be reinforced, in case the Holy Fire Cult takes advantage of the protagonist to go out to the shelter and brings a bomb or something.

This novel is good.

Not bad, worth a look

It's okay, at least I think it's better than most

Although it is not finished, the previous content is really exciting.

This is a good novel. The shortcoming is that it is too short. As for the rest, don't take it too seriously when reading the novel. The most important thing is to have fun.

Hurry up and update it all at once! 😄😄😄😄

Hahahahahahahahahahahaha ok

It looks okay, the author still needs to work harder😄
