Rein had already gotten access to the eternal fire after having sex with Hana. Not only that but as he had managed to get it directly from the will of the Desolate Plains itself, the amount of origin flame that he had inside him was insane.
So now he was capable of bringing all the powerful monsters of the Desolate Plains, including Hana's humanoid body outside. This was an insane amount of power that Rein now had access to.
Now one might have a question that if solving her problem was this easy, why had Hana waited this long to have sex with a man to create a carrier for the origin eternal fire. The reason for that was very simple. There was almost no one except for Rein who was capable of withstanding the power of the eternal fire.
If any other person had have sex with Hana, they would immediately be turned into ashes by her eternal fire.
The only reason why that did not happen to Rein was because, he already had a very powerful fire control ability. The reason why Hana was tasting Rein was because she wanted him to have enough strength to stand on an equal level as her. But during this test, she also noticed that Rein's ability to control fire was top notch. Even though he used his ice power more, for an expert like Hana, just some little clues were more than enough to see through Rein's ability.
That was the reason why she was so excited after meeting Rein. Just as she had realised that Rein had the ability to become her partner and to turn her into a woman, she had immediately become horny and her pussy had gotten wet. So if it was Rein, she would not be able to go out of her area of influence.
...
There was another way which was to ask help from other danger zones but this was going to be extremely situational. There was a high chance that none of the danger zones would be able to send the monsters out and finding a way for them was way too time consuming. There was also a possibility that those danger zones would not want to co-operate with Rein and the others. And most importantly, Hana was against any other danger zones joining them. So Rein dismissed this plan.
As he alone was not able to come to a final decision, he decided to ask his reliable partners for suggestions. After getting everyone's opinion, it was decided that they could start by targeting the danger zones. Hana had a close connection with the will of the world and she also knew a lot about this topic.
She explained to Rein that the more parts of the will the evil danger zone would be able to consume, the harder it would become for him to consume the remaining parts. So even if only the last 10 percent of the will was left, the evil danger zone would need an astronomical amount of time to consume that.
From what Hana was able to judge from the world itself, the will still had at least 30 percent or more portions remaining to be consumed. So that much area could not be consumed in a short amount of time. So instead of risking their lives without knowing about the enemy to save a little time, it was much better to progress slowly and steadily while learning more about their enemy.
Listening to all this, Rein was also convinced. He immediately decided to start targeting the danger zones from the very next day. After this decision was made, Rein was about to end this meeting. But before that he was pushed down by Ruby and got his clothing striped.
Then three hungry and thirsty ladies and an innocent little girl surrounded him. Obviously the thirsty ladies were Sophia, Ruby and Hana. As for the innocent girl, that was Prucia.
This day, another girl lost her virginity and Hana's dream of having sex beside her daughter was also fulfilled. Just like that, before the start of a new mission, all the ladies spent their night drowning themselves in lust and pleasure.
