The concentration of spiritual power around him became higher and higher, and after walking down the next layer, Lin Chu felt that the spiritual energy was already viscous as a liquid, and he could ripple the spiritual energy as he walked.

Yes, they are down, not up.

"This tower was originally the magic weapon of the first dean, and it was a half-immortal level. Gu Tiancun walked slowly on the steps in the tower.

The five levels of instruments are divided into law, spirit, treasure, immortal, and sacred.

The magic weapon of the holy weapon level has always only existed in legends, and the highest level magic weapon in the Xiuzhen Federation is only an immortal weapon, and there is only one immortal weapon known to the Federation at present, that is, the Ten Directions Hall located in the capital of the Federation, which is a space magic weapon that can shuttle through the void, and the space inside is boundless, enough to accommodate a planet, and the headquarters of some of the most important departments of the Federation are located in the Ten Directions Hall.

Next is the half-immortal weapon, which is a little worse than the power of the immortal weapon, but it is far more than the treasure weapon.

"Why do you want to call it a half-immortal weapon?" Lin Chu asked, since it is not comparable to an immortal weapon, then why not use a title like "Dao weapon", but call it "half".

"I really don't know about this, next time you can ask the teacher of the refining department. This one doesn't matter. Gu Tiancun waved his hand, "This rainbow is surrounded by aura storms, the closer you get to the rainbow body, the more fierce it becomes, and on the outside, although it increases the concentration of aura aura, it is not too exaggerated. Only in this Rainbow Tower can you cultivate without being affected by the aura trend. ”

Isn't it important?Lin Chu faintly felt that this half-immortal artifact seemed to be wrong, but he couldn't think of a reason, so he had to follow Gu Tiancun according to the question in his heart.

"There are ten floors inside the Rainbow Tower, and the concentration of aura in the upper five layers is two to five times that of the outside world, while the concentration of aura below is six to ten times. Gu Tiancun stopped outside a room, "This is it, the concentration of aura in this layer is seven times that of the outside, you can cultivate in it for two months." But you have to cherish this opportunity, you know, this has always been open only to people above the foundation building period, and you have this cultivation opportunity by relying on the first place in the double list this time. If you go down, it will be an area that can only be entered during the Jindan period, and you won't be able to withstand that kind of spiritual pressure if you go. ”

"Director, no, I just saw that there is a shield on the outside of this tower, and those spiritual qi can't come in, so where did such a high concentration of spiritual energy in this tower come from?" Lin Chu had a new question.

"Drawn from the rainbow. This rainbow is equivalent to a super-large spirit stone, so the concentration of this spiritual energy is higher and lower downwards, and the bottom layer is simply the feeling of lying in the middle of the spiritual stone to cultivate, but because the concentration is too high, if you don't cultivate enough, you can't absorb that spiritual energy. Even I can only cultivate at the penultimate layer. ”

"Then why don't the academy build a few similar places, I just saw that the body of the tower is only six rooms, which can't accommodate many people, and why can't you cultivate outside, but enter the room." With so few rooms, shouldn't we make the most of the space in the tower?"

"That's a lot of thinking. Gu Tiancun looked at Lin Chu approvingly, "The aura of this rainbow under you is so tightly condensed that you can't imagine it. Because this rainbow tower is a long-term sacrificial thing of the first dean, it can be said to have the same origin and breath as the rainbow under him, which can decompose the aura on the rainbow body, as for other magic weapon academies have also tried, it is impossible to decompose the rainbow body aura at all. Otherwise, the academy wouldn't have put so many cultivation resources in vain. ”

"And the need to practice in the room is because the aura outside is constantly increasing and changing, the process of absorbing and decomposing the aura in this rainbow tower is not very stable, and there will be a wave of aura from time to time, although the intensity is not large, but the impact on cultivation is great, the concentration of aura that fluctuates strongly and weakly requires the cultivator to constantly adjust the absorption speed, and the efficiency is much lower. Only because of the stable effect of the magic circle in the room will the concentration of aura be maintained at all times, which is suitable for cultivation. ”

"It's also because of the scarcity of rooms that this cultivation opportunity is so rare, you don't want to waste it. The other larger rooms are where several people practice together, and they have some influence on cultivation, but I specially got you a single room in this room. ”

"Let's go in, this is the Chronograph Jade Jane, and when the time is up, you will be teleported directly out of the tower. Also, this is Bigu Dan, take it. Gu Tiancun pushed open the door of the room.

Inside the door is a small stone room, only one bed can sit and sleep, and everything else is empty.

Lin Chu sat down cross-legged and began to cultivate without stopping. That's seven times the concentration of aura.

......

In the academy, Meng Danchen was watching the rainbow conjured up from the Rainbow Bridge.

"It's not good to cultivate. Wei Zeban fell from the sky and landed beside her.

"I'm waiting for you. Meng Danchen walked over excitedly and hugged Wei Zeban's arm, "Dad, I've done what I entrusted you." ”

"Alright, alright. Wei Zeban scratched Meng Danchen's nose, "I said when did you little girl get so tired of your father, it turned out that it was still for others." What's so good about that Lin Chu, you are so concerned?"

"yes, Dad, you're so nice. Meng Danchen cheered.

"You, you, it's not a big problem on my side, but you've thought about your mother's side, your mother is a face-saving person, and a weak spirit root can't get into her eyes. Wei Zeban doted on his daughter hanging on his arm.

"Dad, what are you talking about? Lin Chu is just a good friend of mine, what's the matter with my mother. Meng Danchen shook Wei Zeban's arm and coquettishly.

"Oh, it's just a good friend, not a boyfriend? Then he gave you the Rainbow Bridge, and you helped him run before and after, which almost made your dad dizzy. ”

Meng Danchenqiao's face flushed: "What, Ah Niu is really just a good friend." Isn't it right to care about good friends, and you don't know that I didn't have any friends since I was a child. ”

"Say whatever you want, Ah Niu and Ah Niu are so affectionate. But you have to be mentally prepared, I definitely can't help it on your mother's side, you see that you even follow her surname. Wei Zeban shook his head slightly, this is a person from the past, the situation between men and women will not be clear, not to mention that he knows his precious daughter so well.

"Dad, I won't tell you. Meng Danchen stomped his feet and ran away with a red face.

When my daughter is older, she will always have her own life. It's just that my heart is always sour.

Lin Chu? It seems that I have to go and check the bottom of this kid again.

If you dare to have a little bit bad with my daughter, hum.

Wei Zeban looked at Meng Danchen's deer-like figure and thought secretly.
