The Dungeon Conquerors: Journey to the Peak

Even after the end of his trial, Rein's work in this world was not completed. After reaching an agreement with Machina, Rein and everyone else first returned back to the base camp to give everyone the good news.

While Rein and the others were busy going deeper into the core of the danger zone, the fight between Rein's army and the insect army had reached an all-time peak in terms of intensity. Millions of insects died and some of the humans also breathed their last. So the news that they had won the war and had managed to save the world was a news of relief for all of them.

There were a few people who were not so happy that these bugs had now become their comrade but after learning that the Will of All Chaos was actually immortal, they had to accept that this was the result that they could get.

None of the people present here were fools. They all had been through thousands of battles and knew that even if they could seal the will of All Chaos, as an immortal being, there was a high chance that she would be able to come out in the future. At that time, the world would truly be doomed again. So coming to an agreement and saving the world completely was definitely the best result that they could hope for at this moment.

So after the discussion with the other YR grades was over, everyone started their preparation to return back to the surface world. The battle did not last for too long which was a good thing. But quite a few UR grades had died here so Chris, Rein and other top grade UR grade decided to take the responsibility to protect their home nation in their place. This was the least they could do to honour them.

So just like that, everything returned to normal. Even after the mission was over, Rein and Sophia still continued their competition to become stronger than each other. Even after they officially got married and had kids, they did not stop this competition.

Not only Sophia but Ruby, Hana and Prucia also got married to him and they also had kids. But this was not surprising as even before the grand world saving battle, all of them were already having sex.

But there was a surprising addition to Rein's harem that no one had thought of before and that addition was none other than Machina. After about 10 years since the grand battle, she suddenly came out of the core of the world to the surface civilization.

She was actually feeling bored after she had almost nothing to do for almost a decade. For the last thousands of years, she had always been busy with her schemes and with her sucking of the world's energy. But now as she had nothing like that to do, she was feeling very bored.

So she came to the surface world to have some fun. And as Rein's group were the only surface dwellers she was familiar with, she obviously came to them for help. Rein was fine with helping her out so he escorted her around the world.

During this time, Machina came across Rein and Sophia fighting each other and she also got interested in it. So she challenged both of them for a practice bout. She still remembered how dominant she was in the great battle where even with a team of many people, Rein's group was having trouble matching her.

So she had also expected that to be the case here but what happened next completely astonished her. Rein and Sophia did not need to team up at all and just one of the alone was able to completely destroy Machina in battle.

This was so surprising to Machina that she almost lost her mind. It turned out that after getting some proper time to finally completely grow up, Rein had become astonishingly stronger in the last decade. And even more surprisingly, Sophia had actually managed to keep up with him. So much so that now they were able to defeat Machina on their own.

This result did not sit well with Machina, so after a decade of no goal in life, Machina finally had a goal which was to become even stronger. So while travelling around the world, she regularly started having practice matches with Rein and Sophia.

During this time, Machina got interested in what Rein and everyone else was doing in the nighttime and with Hana's suggestion, she ended up joining in one of the session. It had already been two years since Machina came to the world and she had already became a part of the family. Even the kids were calling her as aunty Machina.

Just like that, Machina started a relationship with Rein and after about 3 months, she also decided to officially get married to him. So finally Rein ended up with five wives in this world.

...

Just like in the previous world, after spending a long long time with one another, finally Rein decided to go back. With the support of Machina, all her wives were also immortal just like her. Rein had also already told them about his real identity as after he was done with the trial, the restrictions on him regarding this were gone.

He had already thought of a way to stay connected with all of them but that possibility to become a reality, he first needed to complete his final trial. So while all his lovers waited for him in the depths of the danger zone, Rein disappeared from the world to start his final trial.

In the viscount family of Markarm, the atmosphere was festive and tensed at the same time. That was because today was the day when the mistress of the family was about to give birth to her first son. That was the reason for the festive atmosphere.

But a few days ago, the health of mistress Markarm started declining, so everyone became a bit worried for both the mother and the child's health.

But nothing like what they had feared happened and a red haired boy was born. The Viscount decided to name him Rein.
