After investigating the tower thoroughly, Ste found this tower to be extremely moreplicated than she had previously estimated. This tower was definitely an artificial item and the person who was responsible for creating it was definitely very powerful. Probably even stronger than current Rein.


    So, Ste put the tower aside for the time being as she would need a lot more time to repair it. So she woulde back to this at ater time. Ste now needed to focus more on the next inheritance item.


    So, the next ce that Rein and his party was going was the Lake of Nirvana, the third inheritance.


    This ce was supposed to be located inside a secret realm and the entrance of that secret realm was supposed to be blocked by several powerful formations created by the formation masters of the royal family.


    It did not take them long to reach the ce with several short teleportations from Tasha. The entrance to the secret realm was supposed to be located inside a dense forest filled with monsters.


    Rein did not want to be disturbed by them while searching for the secret realm, so he just used a powerful presence concealing barrier to hide from all the monsters and beasts.


    They were soon able to find the entrance and the formation too. Unexpectedly the formation was somewhat intact but with just arge broken area that had transformed this formation to also be a trapping formation. Currently this formation was imprable from both inside and outside.


    It looked as if a person had just attacked the formation once, changed it in this manner and then left.


    So, Rein and his party needed to break this formation open forcefully to actually enter the secret realm. In its current condition, the whole formation was just a mess and it was impossible to be understood in an intellectual and technical sense.


    Both Ste and Tasha took their time to prepare their strongest attack and attacked the barrier with it. This made the barrier to ripple first and then some tiny cracks appeared on it.


    But that was all and it turned out that the barrier also had a self repair function and the cracks disappeared almost as soon as they appeared.


    That made both of the girls to sigh in disappointment. They had expected it but it was still a sad thing. Currently they were way stronger than their previous self and were almost as strong as the post great dungeon Rein. But still they were unable to deal any significant damage to the barrier.


    That meant that if the conquerors had encountered this ce a few months prior, then they would have been unable to deal anything to it.


    But now Rein was stronger than before after he got his power ups from thest conquered dungeon. Even then Rein was not sure if he would be able to easily break the barrier or not. The person who was able to sh a barrier like this so easily was definitely someone extremely powerful.


    Way more powerful than even Rein.


    Kagura transformed into her sword form and Rein held her. He did not use any of the skills of the sword and just executed the Sword King Art: End Horizon to test the strength of the barrier. The result was even more underwhelming than Rein had expected.


    It was able to prate the barrier but it turned out that this barrier actually had sevenyers stacked on top of each other. It waspressed so well together that even Rein did not notice it with his Eye of Truth.


    He did notice that the barrier was thicker but he missed that there were actuallyyers in this barrier.


    Rein''s End Horizon was able to prate five of theyers fully and the sixthyer was damaged just slightly. So it was not enough to break it. But now Rein became confident that he would be able to actually break the barrier if there was no other special gimmick attached to it.


    This time Rein did not hold back and activate all of his abilities. His body started to shine with a golden light and at the same time crimson lightning started to crackle on it. Kagura also activated limit break, potential release, supreme essence, heavenly aura and more.


    That was enough to help her in reaching the absolute peak of power Rein was currently capable of using.


    With all that power Rein performed his new Sword King Art that he developed with Kagura just recently and this art was called "Deity''s Fall".


    Immediately there was a shattering sound like ss breaking and the powerful barrier that was extremely powerful even in the old days broke and disappeared after that.


    Now a downward going set of stairs became visible to everyone. It just looked like a normal stair, but anyone a little bit knowledgeable would be able to feel the spatial aura around the set of stairs. It was definitely a magical portal connecting with a different dimension.


    After going down the stairs, all four of them found themselves in front of a gorgeous lookingke. The water of theke had the colour of faded grey and even though it looked quite beautiful, there was a scary feeling around it too.


    This ce was definitely not for everyone and quite a few deaths had happened in thiske.


    Looking around Rein saw the skeleton of a few people wearing gorgeous but tattered dresses. There were also a few skeletons who were wearing armours and robes like knights and mages. It would not have been a weird sight if this whole ce was filled with such remains but that was not the case.


    Only one part of this ce had these remains.


    Before checking the Lake of Nirvana out, Rein and his lovers first went to investigate those skeletons. What that found was quite fascinating. All of these skeletons were millions of years old.


    Normally it would not have been possible for them to stay intact for so long but the special nature of this ce allowed them to stop the decay with the passing of time.


    All of them were carrying quite a few magic items with them and those magic items were of decent quality. From that it was evident that they were definitely from a higher level of the society as even in olden days, magic items were still very rare.


    But still Rein had no idea who these people actually were but there was a way to find out. There was a dairy alongside these people and the diary itself was a very powerful magic item. So it was more or less intact even after such a long time.


    There was a very high chance that this dairy would have the information that Rein and his party were looking for.


    Ste started to decipher this dairy while Rein and Tasha went to check theke out. Kagura was staying with Ste as she was immediately able to tell that the Lake of Nirvana would not have any effect on her. She was sure about that and it made sense.


    Increasing the potential of an Eternal grade weapon which had already reached the absolute peak of quality was not so easy.


    It did not take too long for Ste to decipher the diary. She had already learnt thenguage that was used in the book and this diary was also written in the samenguage. So it was just a straight forward reading to her.


    The only reason she still needed to take some extra time was because, the person who wrote this diary was not very good at thisnguage. So he made several mistakes. So Ste needed to correct them too and that''s where she needed to invest most of her used time.


    Rein and Tasha were already fine testing theke and were a little bit disappointed. Tasha found that bathing in thiske was actually good for her and her powers did increase by just a little bit. But that amount of increase was useless to change her overall strength. But that made sense.


    Tasha was a Primal Beast, someone whose potential was already at the very top. So theke of Nirvana did not have much effect on her.


    As for Rein, he also did find thiske to be pleasant and his powers also grew a little bit with time. But then again the amount of power increased was very low even whenpared to Tasha. So he also did not find thiske to be too useful and came out of it.


    As soon as he and Tasha returned to where Ste and Kagura were, they saw a very excited Ste. When Rein asked her what happened, she happily replied that she was able to find something very very interesting and now she even has an idea about how that powerful ancient nation was destroyed.


    This the owner of the diary had written all that in hisst dying days and as he was actually a member of the royal family, he knew a lot of truths that others were unaware of. This was truly a great discovery.


    So a very excited Ste started to tell them what was written in the diary and three interested audiences heard her with a great amount of attention.
