Chen Nan was completely immersed in the mystery of the runes, and he didn't move for a few days, seeing that he was participating in the formation of enlightenment, several women also took out their own forbidden methods, some cultivated, and some also began to comprehend the prohibition of the formation, after all, being in such an environment is also conducive to their comprehension of the prohibition of the formation, and if you don't understand, you can ask Chen Nan.

This enlightenment, unconsciously, has been half a month has passed, Chen Nan opened his eyes, stood up again, and his confidence has obviously increased a lot compared to before.

"Husband, are you sure?" Several women immediately surrounded them, if they missed the magic weapon of the cave mansion, it was really not what they wanted, they were more anxious than Chen Nan.

"Eighty percent sure. Chen Nan smiled.

Several women had joyful expressions on their faces, at least they saw hope, and followed him to the stone room.

Chen Nan came to him, still suppressed the sword intent with the sword intent, only observed the time of less than a stick of incense, stretched out his hand to break the prohibition of the fourth layer, and then wasted a little time, and successfully broke the fifth layer, but it was difficult to reach the sixth layer, but he used the anti-heaven of the Yantian Holy Technique, and after repeated deductions, it was still broken.

Broken the six layers, there are still the last three layers, which can also be said to be the most difficult three layers, these nine layers of prohibitions are obviously difficult to break from Jane, one layer is more difficult to break, just relying on these prohibitions, Chen Nan has mastered the application of more esoteric runes, his current formation level is stuck in the fifth layer, and understanding the meaning of these runes will naturally be of great benefit to the future advancement of the formation level.

The seventh layer, Chen Nan repeatedly deduced, during which he continued to go outside to comprehend the runes on the stone wall, and it took a day to finally break it, but the eighth layer, no matter how he deduced, it was difficult to break it with the level of the formation, this prohibition was really complicated, and it had reached the critical point of his formation level, maybe it could be broken after ten years of research, but the time was too long, and he couldn't afford to wait at all.

"Just a failure?" Chen Nan bit it, and when he looked back and saw the women's eyes full of expectation, he was really unwilling to fail. He suddenly had an idea, for nearly a month, he has been using the formation level to break the formation, but he ignored one point, in addition to relying on the level of the formation to break the ban, he can also break the law with force, why don't he try to attack the ban?

Chen Nan's divine sense penetrated into the eighth prohibition, after all, his understanding of the rune prohibition had improved qualitatively in the past few days, and it was easy to discover the weakness of the prohibition, although it could not be broken with the level of the formation, but it was not difficult to forcibly break it with force.

But he quickly thought of a question, to break the law by force, even if the ban is broken, will the old cow admit it?

"Husband, do you want to break through the formation?" Bing Mei asked, actually seeing his thoughts.

"Hmm!" Chen Nan nodded, "I just don't know if this is considered a broken formation." ”

"How can it not be considered to break the formation? After all, the old cow senior didn't say it, no matter what method is used, as long as it is broken, it should be counted, right?"

"Yes, why doesn't it count as a strong attack, it didn't say, Sister Lily was almost injured at the beginning, it should be counted. Shen Qiuhe also agreed.

Yang Li also nodded, "I didn't break it when I started to attack, and forcibly breaking the formation is also a reflection of strength, not to mention that even if I attack strongly, not everyone can break it, didn't I break it?"

Chen Nan nodded, what a few people said made sense, but the old cow didn't say that he wouldn't let the attack, no matter if he could do it or not, he might not be able to break it if he said it.

With this thought, Chen Nan sacrificed the blood shadow, and directly slashed at the weak point of the prohibition, and the prohibition shook, dissolving his power invisibly.

"Didn't break it, the prohibition was still stronger than I expected. He didn't do his best with the blow just now, and at this time he didn't have any reservations, and slashed at the weak point of the formation with all his strength, and with a "boom", the prohibition finally collapsed, revealing the last layer of prohibition inside.

Thinking that as long as this layer is broken again, you can get the magic weapon of the cave, Chen Nan is also very excited, several women's beautiful eyes are shining and looking forward to it even more, women are the most enthusiastic about the new house and home environment, the magic weapon of the cave house is much more attractive than the new house, if it fails, they are even more disappointed than Chen Nan.

Victory is just around the corner, but Chen Nan also knows that the closest time to victory is also the easiest time to fail, under observation, he can't help but be surprised, this last prohibition, he didn't find any flaws, the eighth prohibition just now, if you don't find a weakness, even if you break the law with force, it is difficult to break it, this ninth prohibition is even more difficult, there is no weakness, if you want to break it, it is simply impossible.

The last layer just gave up, how could he be willing, Chen Nan said hello to the women, and the figure suddenly disappeared and entered the Qinglian world, the duck egg was still in the cocoon, but the luster of the cocoon disappeared, and it became more plain and simple, presumably it was not far away.

Now Chen Nan has no time to think about duck eggs, getting the cave genius is the current top priority, he came directly to the small sapling, and used the small sapling to help settle down and increase his understanding.

With the help of the little sapling, Chen Nan was very open to abandon distracting thoughts, and wholeheartedly comprehended the last prohibition, three days passed in a blink of an eye, Chen Nan stood up with a smile on his face, he had found the weakness of the last prohibition, and his mind appeared outside the Qinglian world.

Seeing Chen Nan's confident smile, the women knew that there was hope, and they also breathed a sigh of relief, full of expectations, after all, although Chen Nan's Qinglian world was advanced, it was not inhabitable, with this cave magic weapon, they could follow him in the future, and they were naturally extremely looking forward to it.

"Hum!" Chen Nan slashed at the weak point of the prohibition he had just discovered with all his strength, and the prohibition rippled, once again dissolving his strength into invisibility.

But Chen Nan was not discouraged, and asked the women to retreat enough distance so as not to hurt them, and then hundreds of thousands of heavy sword shadows came out, and the dense knife rays compressed into a red line, slashing at the weak point of the prohibition with all their might. "Click!" finally made an indiscernible sound.

Chen Nan smiled, which showed that his attack had an effect, and there was a crack in the ban, and at the same time, the ban was rippling and was being repaired.

If it is repaired, his knife will be in vain, Chen Nan does not dare to slack off, "Click!" He continued to slash out, each knife tried his best to compress the knife and slash at the weak point of the prohibition, under the continuous attack, the speed of the prohibition fragmentation was greater than the repair speed, and the crack became bigger and bigger, and finally after he attacked hundreds of knives with all his strength, the light flashed, and the prohibition finally completely shattered.

In front of their eyes, there was a small cave house that exuded a crystal luster, and it was beautiful.

Seeing that the old cow didn't come out, Chen Nan grabbed the cave in his hand and tried to refine, as long as he could refine the cave, the spirit of the cave would naturally be controlled by him, and he couldn't recognize the master if he wanted to.

However, under the infusion of mana, Chen Nan couldn't refine a layer of prohibitions for an hour, not to mention the complexity of the prohibitions inside, let alone how many there are, if you want to forcibly refine, it is almost impossible.
