When he saw the mobs he instantly ran. He was sprinting though the complex cave system looking for a way out even if he has been mining for months. The mobs were right behind him and he was only going deeper into the cave. He quickly blocked for his back with wood and crafted tnt and a redstone torch. The mobs caught up to him and exploded his makeshift wood barrier. He ran further down and placed the tnt. As the mobs walked up he lit the tnt with his redstone torch and ran as fast as he could back. The shockwave from the explosion threw him 40 blocks forward. He was scared but he didnt get hurt because he landed in cobwebs. Then he realized the cobwebs were from a spider spawner. He got his sword from his inventory while the cave spiders drew closer torward him. He mined as fast as he could to break the cobweb.He finally broke free with one of the spiders hitting him. He stumbled away, poisoned. He kept trying to go up and remembers a path he took down in the cave. He starts climbing block by block with his health going down. The path he took was a exit from the cave but when he got out he realized the worst thing. It was night time.
