The words of the illusory figure echoed in Aisen's heart for a long time, but what made him most curious was the "heart of the brave" in the mouth of the illusory figure.

If, as the illusory figure says, the "heart of the brave" can lead him to become a true knight, then this thing must be something extraordinary.

But what the "heart of the brave" was, the illusory figure did not explain to him, and Aisen couldn't figure it out for a while.

"Xiao Senzi, what is the little bright pagoda in your dantian, it actually exudes the power that makes me fearful," the Red Dragon King in the magic source suddenly spoke.

"What are you talking about?" asked Aisen to the Red Dragon King in confusion.

Although Aisen knows from martial arts novels that dantian is the ancestor of life, the source of anger, the foundation of the five internal organs, and the place of the sea of qi, but in the end, this is also an illusory thing, and there is no substantive definition, so Aisen's concept of it is also extremely vague.

"No, you don't know what a dantian is, it's really convinced, the source of the magician's power is the magic source, and the knight's source of power is the dantian, that is, the location of the limiter, every time you break a limiter, the origin of the human body will erupt from the dantian and spread to the whole body to achieve a reborn enhancement" The Red Dragon King explained to Aisen who was at a loss.

"Oh, no wonder there was a warm feeling in my lower abdomen when I became a knight, so the 'heart of the brave' is in my dantian?!" Aisen said with his eyebrows raised and a little surprise.

"Then how do I communicate with this dantian," Aisen asked the Red Dragon King

"Hold your breath and concentrate and connect your mind to the dantian, and you will be able to see the space within the dantian," the Red Dragon King replied

Soon, Aisen came to the space in the dantian through his mind.

Although it is space, it is not a layer of qi sea, the qi sea spreads out from the gate in the dantian, and that gate is naturally the first limiter opened by Aisen.

"This is the sea of qi? it's better to see than to hear, this sea of qi is quite spectacular," Aisen said secretly in his heart as he brushed his hand across the ethereal mist.

Eisen walked slowly to the limiter, and behind the first gate was a closed gate, which was tightly sealed by five forbidden chains, and these chains were the confinement of the human body.

And the illusory figure said that the "heart of the brave" is in the sea of qi.

This "Heart of the Brave" is a small tower as the Red Dragon King said, but it exudes a peaceful and sacred atmosphere.

"Could this be what Ryan said about the "Heart of the Brave", how is it a tower?" Aisen thought puzzled, and made a lot of conjectures about the "Heart of the Brave" Aisen, but he didn't expect it to be a tower.

After observing for a long time to make sure that there was no danger, Aisen touched his hand, and as soon as he touched the tower, a powerful suction suddenly erupted, forcibly sucking Aisen into the tower.

Inexplicably sucked into the tower, Aisen was also extremely puzzled, but fortunately, there seemed to be no danger.

The inside of the tower is like two worlds outside the tower, the inside of the originally small tower is so large, and the place where Aisen is located is the first floor of the tower, as for how many floors this tower has, he doesn't know.

Just as Aisen was exploring around, an ethereal and kind voice suddenly came from inside the tower, "Since you can come here, it means that you must have passed my assessment, and I named this tower "Heart of the Brave" ,And its existence is to guide you to break through the limit of the god name knight,In front of the king of the demon race, the god name knight is still too weak,In desperation, I can only start this god-making plan,The tower stores my lifelong learning and the research experience of the nature of knight power,And there is also an opportunity to break through the god name,But the key is still you,Child, I know it's cruel to let you bear such a big responsibility.,But for the sake of all mankind I beg you to go down this difficult road.,In the near future,I hope you can make up for my mistakes and save mankind from the hands of the king of the demons. 。 ”

The ethereal sound passed, never to be heard again, and the tower fell silent again.

"Is it really possible to break through the god's name?" said Eisen to himself.

"Red Dragon King, do you know what realm is above the name of the god?" Eisen asked the Red Dragon King in the magic source.

"I don't know, Ryan, who was known as the Sword God at the time, may be the closest knight to the god name, and if it weren't for the attack of the demons, he might have had access to the god's name," the Red Dragon King replied.

"Or maybe Rien's predecessors had already noticed something at that time, so that they left this "brave heart" to enlighten future generations," Eisen said thoughtfully.

Eisen then checked the first level of the tower again, and there was only one staircase leading to the second level, but there seemed to be a powerful barrier at the top of the staircase, blocking his way.

It seems that the tower only allows Eisen to enter the second level when he reaches the Golden Knight.

On the first floor are three bookcases, filled with books, which may be what Ryan has learned and studied all his life.

Eisen then found a copy of Ryan's research notes from a bookshelf, which recorded Ryan's research.

"In my years of research with Shakya, we finally discovered that there is a mysterious medium that can block the inhibition between the limiter and the magic source, but due to the particularity of this medium, I am afraid that there will be no magic knight double cultivators in the world" There is only a simple paragraph on it, but it does not seem to be fully recorded.

"Well, why didn't it say what this medium is, could it be that the rest of the records are on the next layer?, but since mages and knights are not absolutely unable to cultivate at the same time, it means that this path can still be opened," Aisen took his research notes and smiled happily.

Although the method is not documented, it is not hopeless.

Later, Eisen found a medium sword technique called "Continuous Fencing" from another shelf, which was Lane's famous sword skill at a young age.

The strange sword track, the fast sword, so that he is unrivaled in his generation, according to the above records, even fencing has a maximum of ten swords, and the power of each additional sword will increase significantly.

"This fencing combo is really extraordinary, if you reach the realm of ten swords, it is not even inferior to advanced sword skills," Aisen sighed.

After memorizing the sword trick in his mind, Esen left the Light Tower and returned to reality.
