The End of the World: My Item Upgrade Properties Are Off Track

The virus broke out and a large number of humans turned into zombies. In order to survive, people began to build shelters. At this moment, Jiang Yan not only opened up the system space and stocked up a large amount of supplies, but he was also able to upgrade the items. Upgraded baseball bat: The attack power is increased by 100%, but the price will be like stick-like items. It lasts for six hours and the price for women is doubled. Upgrade the knife: After cutting the target, the probability of tetanus increases to 90%. The price is that the front knife becomes the back knife. You can only attack others with the back of the knife, and the lethality of the blade is almost zero. Upgrade the chainsaw: The sound of the chainsaw is worth thousands of gold. This is the favorite tool of lumberjacks. After using it, you will fall madly in love with the feeling of logging... If you want to stop, you must shout three times: Weare tired of logging! ... Looking at the various upgrade attributes, Jiang Yan was dumbfounded. The system is a good system, but are these attributes off track? This novel and its characters are purely fictitious.
