Reincarnated as an Energy with a System

The Dungeon boss took an incredibly long time to beat. The boss was a giant version of the Ore Beast with a much higher DEF stat such that even when Ning did land a hit on him, half the time it barely did any damage.

He seemed to also have a passive that blocked off a portion of all types of damage making it hard to kill him swiftly.

The boss wasn't very fast, but it was still faster than the other golems Ning had seen, and it used the 'Rock Spikes' skill quite frequently.

Ning had seen the other Ore Golems use it from time to time, but he was always on top of them, so the golems rarely ever hit him with it.

However, it was hard for Ning to do the same now, and as such he was forced to fight while constantly moving around to dodge the attacks.

When the boss got to 50% health, Ning wondered what the next phase of the battle was going to be.

That was when the boss suddenly lost his health bar and crumbled into many pieces of rocks on the ground.

While Ning was confused, the stones moved back up to form 2 different smaller bosses who had half of his health and slightly lower DEF.

Overall, their HP was still the same as the Boss's when it was 100%, but with lower damage reduction, Ning had a slightly faster time killing them.

Although that also meant that he had twice as many attackers he had to dodge around. And he definitely had to dodge around.

A level 150 boss, even if he could damage it, dealt insanely high damage. Even at half-state, it dealt over a thousand damage on each hit, making it pretty much impossible for Ning to stay in their attack range for a long time.

As such, the time it took to kill them ended up being significantly longer.

The two golems split up once again to become 4 different golems once they both reached 50% health. Ning was worried that it would continue doing the same for a while, but fortunately, that was the last time they would split.

After continuously dodging around for a while, Ning finally managed to kill all of them and successfully cleared the dungeon.

In doing so, Ning leveled up with just that single boss. If he went through the entire dungeon again, he would surely reach 103 with ease.

He got a few ores, most of which were Black Iron, and a skill book for the rock spikes. He also got a defensive item, but Ning didn't want to wear it so he let it be.

The armor decreased attack speed to give you defense, and Ning didn't like that.

Aside from that, Ning also got a single stat to his STR stat due to his Demon's stat skill, but that wasn't as important to him since he had been getting them the entire time he fought the other golems on the outside.

The portal to leave appeared and Ning walked through it. He arrived on the other side, holding a pickaxe in his hand with a few people walking past beside him.

They looked at him curiously and wondered if he was perhaps a high-ranking player since he had soloed this dungeon.

A few of them even asked him that, which made Ning think about what he was doing. He was beating a level 150 dungeon as a level 100 player.

"Ooh, this should make the highlights, right?" Ning thought. He looked at his inventory quickly and saw about 160 different Black Iron ores in there. If he did everything right, he would surely have about 200 definitely. This meant that in just 2 more dungeon runs, Ning was going to find all the ores he needed to complete the quest.

Ning wanted to speedrun the dungeon, but the quest came first. So, he walked into the dungeon again and spent a lot of time mining for Black Iron.

This time around, he ended up gathering about 180 Black Iron ores.

Ning came out as a Level 103 player and went back in again to find more Black Iron. He came back out with 185 this time around.

The number he had now was easily over the 500 required to defeat the dungeon, so Ning decided to see how fast he could clear it. If he got a record, he would post it online.

Ning stayed outside for a while making the perfect preparation to defeat the solo clear record of 15 minutes. Once ready, he went it.

…

It took Ning 3 different times to beat the record. The first time around, he fought everything around him quickly, while also finding his way to the boss's room. That turned out to be a bit too slow.

The second time around, he went into the boss's room directly and the other beasts followed him. However, Ning was too focused on dodging and forgot to attack quite a few times due to the sheer number of enemies.

Finally, the 3rd time around, he got himself a defensive spell and an offensive one to compensate for what he lacked, and easily cleared the dungeon in just 9 minutes.

Ning could only wonder how well he would've done had he more levels.

After coming out the third time, Ning left the mines and went back to the keep where he found the blacksmith and gave him the ores.

"Woah, you really did it? I'm very surprised," he said. "Let's see… 688 ores. Well done. Here's your reward."

Ning saw a bunch of notifications telling him that the quest had been cleared. He also got a bunch of money and enough experience to level up 3 times over. Now, he was close to Level 115.

"Tell me, what sort of weapons do you want?" the man asked.

Ning thought for a moment and told the blacksmith exactly what he wanted. A single-handed spear with rather heavy damage.

"Hmmm… that will take some time," the blacksmith said. "It will take at least a month for sure, but don't worry, I will make it in time before the major war ."
