Other than his personal strength, his dungeon has also gotten stronger. He not only increased the area around the dungeon, but also made underground tunnels and a second floor. These tunnels connect to the second floor which is inside a pocket world.
Though it cost him 50000DP to buy it from the store, he had no other option. He couldn't build a proper dungeon without a pocket world. With this pocket world he could now create as many floors he wanted without having to dig underground. He wanted to build a tower which would have a pocket world for each floor. But he didn't have that much DP.
A tower comes with in built function to create new world for each floor which would cost much more than the normal floor. He decided that he would build a tower later when he has more DP to spend.
Now his first floor has goblins and kobolds occupying half the space each. They almost fight each other everyday. Whether its for food or to increase their territory.
To solve this problem he wanted to expand the 1st floor but DAS gave him a better option. He could manually expand his territory without spending much DP by using a item called 'Map Expansion Crystal'. All he had to do is he would explore an area around his dungeons boundary and use this crystal to occupy that area.
This way he would get free space. But the downside was that, these area couldn't be changed. Meaning whatever the topography is, it would remain the same. Even the monster inhabiting the area would remain.
DAS informed him that when he would go outside his cave, he would gain a feature called map. Whatever place he travels, that place would be added to his map. This way he wouldn't get lost. Though he was busy training with all the manuals, he decided to use it when he would go outside.
Now that he has the strength to fight, he is planning to explore his surroundings and add them to his dungeon.
Before that he wanted to upgrade his dungeon to next level. Currently his dungeon was F level. Hence he couldn't get any more options to select monsters. Upgrading it to the E level would give him more monsters of F level and E level.
Also from this point onwards, the barrier that warns goblins and kobold of danger would be removed. Any monster could get attracted to his dungeon. Before it was restricted to F level only. But once upgraded, even more powerful D, C, B, A, S, SS, SSS class monster would know there is a dungeon nearby.
Though he is safe because of the default defense of dungeons to protect its lord, he would not take any chances. He had already spent 5 years inside a cave just to get stronger and have higher chance of living. He wouldn't prefer to be killed and get his strength reset. That way he had to start from the bottom.

As soon as the upgrade was completed, his dungeon monsters started to walk towards the boundary. Goblins and kobolds formed teams headed by a warrior and a shaman. Slowly, they began to explore the area outside the boundary which they didn't due to the fear they felt when they tried to.
Now they no longer have such fear. Rather they felt curious and their instincts telling them to capture more area under their territory. Goblins and kobolds went in opposite directions. Soon kobold face their first enemy.
It was a fire lion. It looked like a typical lion except it was much bigger and its mane was covered in orange flames. It was not alone. It had it's group behind him. This group was one of the overlords near the dungeon. The leader was looking ferocious and powerful.
Raizel who was watching from his screen, knew instantly using his skills that the lion was an E class monster. Also everyone in it's group were F class monsters. He knew kobolds were dead as soon as they met this group.
Before he had seen this group coming closer to the dungeon but the barrier prevented them. Now that the barrier was gone, these monsters would be among the first group to sense the dungeons upgrade.
He knew he was in a dangerous forest range. There was no nearby settlement of intelligent races. In these five years he hadn't met any of them. But it seems it would change soon.
More and more beasts would get attracted towards the dungeon. Thankfully, according to DAS the dungeon was in the outer region of the forest. Hopefully, powerful beasts would not come here soon.
E rank beast, he could manage. He can test his skills against them. They would provide him the perfect opportunity to sharpen his skills.
After forming a ring, he now could use magic spells. Before he could only use mana to strengthen his body. This is another reason for upgrading the dungeon.
In the store, he would get new Tier 1 and Tier 2 spells. Due to his mana capacity, he could use some Tier 2 spells without having to form his second ring.
