Under Yang Qianyu's intentional or unintentional conversation, the Norn knights who are traveling with him will discover the whole ins and outs of the mysterious waterhole.

In detail, the mysterious waterhole that everyone was going to was not in the kingdom, but near a mountain forest dozens of miles away from the border. The world of Ybers is vast, and the human population living in it is relatively small. The four kingdoms of the current human settlements, that is, the human city-states on the continent, are at least thousands of miles away from each other. In a sense, the four kingdoms of human city-states exist on the continent of Iber as four isolated islands.

And the territory outside the borders of Shikoku is full of all kinds of powerful demonic beasts or races. Among them, there are many Saint-Order Demonic Beasts (also known as 'Sacred Beasts') whose strength is comparable to or even far surpasses that of the Saint-Rank powerhouses - such as the dragon that dominates the sky, the Beamon who is proud of the earth, and the hydra that lies dormant in the deep sea. There are also ferocious demonic beast groups such as fangs, poisonous mantises, flame eaters, and scorpions. In addition, there are areas that are so unsuitable for human existence that they are rarely inhabited. As a result, the main areas of human activity are still concentrated in the regions of the four city-state kingdoms. Only a few adventurous people who are confident that they are strong enough to protect themselves will form their own adventurous teams and go deep into those areas outside the country.

Although the sparsely populated areas outside the country are full of dangers, they also contain endless treasures. Some treasures are hidden in every corner waiting to be discovered. Some of them are rare medicinal herbs, some are precious mineral veins, and many explorers who excavated them have made a fortune from this, which in turn attracts more explorers to explore these wild places. Although there are only one in ten who have really gained, and there are countless people who have died in other places, there are still many explorers who have joined the team of exploring outside the territory one after another.

A few decades ago, when Casya's father, the second patriarch of the Leopolds, inherited the hereditary title of earldom and ran the family domain of Prailly, the second generation of the family organized several expeditions into the adjacent territories of the territory. At one point, the expedition team had reached a distance of 300 miles, but it was only retreated by other humanoid groups outside the territory. Several teams have gained some bit, and the most valuable one is the expedition team that stumbled upon the 'Mysterious Waterhole'.

Back then, after entering an extraterritorial, the team found a woodland after several turns. The trees in that woodland were unusually tall and stout, the most common of them were more than forty meters tall and their trunks were more than two meters in diameter. Moreover, the trunks of these trees are as hard as steel, and ordinary weapons can't even leave a trace when they are chiseled.

Because the trees in this giant tree forest are high and dense, and the situation inside is difficult to understand. The expedition team did not rush in, but found a temporary camp outside the forest. Since it was a campsite, it was natural to find a place that was conducive to camping, so after searching around, the team chose the location of the camp by a waterhole.

Originally, the members of this expedition team thought that there was nothing new about this pool, but later, when one of the team members went to the pool to get water, he inadvertently dropped a short dagger he carried with him into the pool, and then he discovered the strangeness of the pool.

The short dagger that fell into the pool did not sink to the bottom, but floated on the surface of the pool!

The explorers who discovered this wonder hurriedly beckoned their companions, and after some experimentation, the explorers found that the water of this waterhole looked like ordinary pool, but in fact it was amazingly buoyant. Not only short daggers, but also the heavy two-handed tomahawks used by the Warriors of the Strength type are thrown into the pool, and the great axes can still float on the surface of the water without sinking to the bottom. Curious, the explorers found many long wooden sticks connected together and probed into the bottom of the pool, but until all the pathfinder sticks with a length of nearly 100 meters were used up, they did not feel that they had touched the bottom of the pool. In the end, because they could not go down to the pool to explore, the expedition team could only return to Prairly Territory with a few buckets of water.

These buckets of water naturally attracted the attention of the Leopold family, but the Leopold family studied these pools of water, and could not find any other peculiarities except for the great buoyancy of the pool. Later, the friars Akara who settled in Prairly? After Seya came forward to study the pools, she finally discovered that they contained a mysterious energy. Akara intuitively sensed that this energy was very different from the 'psionic energy' of the Iber world, but he couldn't find a way to use it. At that time, the Leopold family also tried various ways to use the energy in the pool water - to make drinks, make potions, use it for bathing, and so on. But this power just can't be absorbed and harnessed by humans. Later, it was unintentional, when the chief weaponsmith of the territory, Chasi, used this pool of water as a quenching coolant when forging weapons, he realized that some of the energy in the pool water could actually infiltrate into the quenched semi-finished weapons through the quenching, and the attributes of the weapons that received this energy in terms of strength, hardness, toughness, etc., were much higher than those of ordinary weapons, and even the texture could be compared to some ordinary weapons of superior quality. This discovery surprised the Leopold family. It's just an ordinary iron weapon, but it is quenched with pool water during the forging process, and the texture of the weapon is comparable to that of a high-grade ordinary weapon forged from some precious materials. You must know that among the weapons used by humans, the number of enchanted weapons can be described as only a handful. The vast majority of soldiers and fighters still use ordinary weapons made of various gold and iron materials, of which ordinary iron weapons account for the vast majority. And today's Prairie Collar can actually rely on exploring the mysterious pool of water to produce ordinary iron weapons with a texture comparable to high-grade weapons, and with this advantage, the armed forces of the Prairly Collar can be invisibly higher than other surrounding noble collars!

Because of this, the Leopold family concealed the mystery of this pool of water, and used it to create a proprietary weapon that belonged to the members of the family's armed 'Rogge Knights'. And the Rogge Knights have the advantage of equipment, plus the knights in it are also strong and strong, and the soldiers under their command are also well-trained. Later, whether it was a skirmish with the surrounding lords, or a national war against the demons in the kingdom, he made countless achievements, making the Leopold family a well-known force among the hundreds of powerful lords and nobles in the kingdom.
