"Then change to the next target, Yaoyao and I have observed in the past few days, because only monks above the Yuan Infant Stage can transform into shapes, so most of the guards in the inner city are half-demons. Half-demons, there are smart and foolish, you can always find a breakthrough!" Fang Huairan said in a good mood.

Zhou Tong thought about it, and since the biggest problem had been solved, he agreed: "Okay, then do it, Huairan, you go in and check it yourself, if you encounter danger, immediately send a signal to me and Yaoyao with the Gloomy Stone, and we will make some movement outside to answer you." ”

Fang Huairan nodded, turned his head to look at Cheng Yao, Cheng Yao frowned slightly and said: "If you answer outside, I will be enough alone, anyway, there are no god transformation stage monks in the Earth Wolf Tribe, I suggest that Tongtong you also go with Huairan, with your Heaven and Earth Xuanhuang Pagoda to defend, even if you are blocked by the wolf clan Yuan Infant Monk, you can find a chance to escape." ”

Hearing Cheng Yao say this, Fang Huairan felt that it was also the same truth, worthy of being a woman, but she was careful, and turned her head to look at Zhou Tong to see what her opinion was.

Zhou Tong thought about it, nodded and said, "It's okay, if we are blocked, we can force ourselves out." ”

Speaking of this, Zhou Tong wiped the storage bracelet, took out a gray and transparent slender horizontal knife, handed it to Cheng Yao, and said, "Yaoyao, you take this, if you encounter danger, use your essence blood to urge it." ”

Cheng Yao pushed it and didn't answer, and explained: "Give me the Heavenly Demon Soul Slashing Knife, then you two have a lot of means, I'm just making some movement outside, it won't be too dangerous, let's keep it for the two of you!"

"You take it, I have the Heaven and Earth Xuanhuang Tower, it is also a spiritual treasure, it is enough for defense, don't forget that we also have the Five Emperors Golden Dragon Banner in terms of attack!" Zhou Tong said again.

"Take it, what if you encounter danger! You don't have the Blue Lightning Devouring Thunderhawk teleportation, and you don't have a powerful defensive magic weapon. Fang Huairan also helped.

Cheng Yao watched the two of them persuade themselves, knowing that now was not the time to excuse themselves, good steel was used on the blade, and the hope of success with more strength was greater, so he nodded solemnly, and put the Heavenly Demon Soul Slashing Knife into the storage bracelet.

Zhou Tong reminded Fang Huairan to arrange a teleportation array, just in case, and Fang Huairan gladly adopted it.

A long-distance teleportation array is placed near the wolf settlement, and the other end of the teleportation array is placed outside the ground wolf tribe, and a teleportation array B is placed in the other direction of the settlement area to dock with the first teleportation array.

In this way, Cheng Yao can lead the enemy away in the direction of the B teleportation array in the residential area, wait for the B teleportation array, and then instantly teleport back to the A teleportation array, join Fang Huairan and Zhou Tong, and teleport outside the Earth Wolf Tribe together.

After arranging the teleportation array, Fang Huairan tested it on the spot, but fortunately, the wolf tribe did not have a formation to confine space.

It took a few more days to prepare these properly, and the three of them acted separately, Cheng Yao hid in the periphery to answer, Zhou Tong entered the mirror of the world, and Fang Huairan went to the road where the confused half-demon often walked to ambush.

Let Zhou Tong enter the Great World Mirror first, is to avoid the mirror hidden on the half-demon at that time, and then teleport Zhou Tong into it to shine and expose it, and Fang Huairan himself is the owner of the mirror, so if the teleportation is slow enough, the blue light can be compressed to a point that is weak and difficult to find.

A day later, Fang Huairan seized the opportunity to return to his residence in the half-demon rotation, and in his residence on the outermost part of the Earth Wolf Tribe, he carefully shrunk the Great World Mirror into a thin mirror similar to paper, sandwiched it into a book he borrowed from the library tower, and then quietly teleported it himself.

Hiding in the book is much safer than hiding it on the half-demon as planned, after all, even if the monk is confused, if he has an extra thing on his body, he will not be unaware.

After a day and a night, it was the turn of the confused half-demon to be on duty, not to mention, this wolf clan half-demon looked confused, but he was a research-type monk who loved to read, Fang Huairan and Zhou Tong saw that most of the time this half-demon rested was studying the classics borrowed from the library tower.

The half-demon took the book containing the Great World Mirror and a few other books, and went to the library tower to guard as usual.

Just after the half-demon entered the library tower through the teleportation array, the formation prohibition of the library tower swept past the half-demon, Fang Huairan did not dare to be careless at this time, and had completely cut off the induction of the outside, and converged the breath of the Great World Mirror to the extreme.

Fang Huairan and Zhou Tong in the mirror, you look at me, I look at you, no one spoke with a nervous face, and after a quarter of an hour, Fang Huairan estimated that the confused half-demon had already entered the library tower no matter what he said, so he cautiously sensed the outside.

Because it was sandwiched in the book, Fang Huairan didn't feel it very clearly, but he could still vaguely sense the rows of shelves, which should be inside the library tower.

Fang Huairan excitedly told Zhou Tong about the situation he sensed, and Zhou Tong couldn't help but cheer anymore.

When the two of them were almost happy, Fang Huairan said: "I'll go out and take a look first, if the formation of the library tower does not react, then it proves that our previous guess is correct, the formation is only external and not internal." ”

Zhou Tong nodded in agreement, and then said uncomfortably: "Although it is impossible for us to analyze the formation internally, it is not necessary to consume a lot of money, but you have to be careful, if it is exposed, you can only break out!"

"Well, I know, we've already deduced it, and you also take out the Gloom Stone, ready to send a signal to Yaoyao at any time. Fang Huairan replied.

After that, Fang Huairan carried the sky light and cloud shadow, and his figure disappeared, and then a faint blue light flashed, Fang Huairan should have been teleported out, Zhou Tong stared nervously at the monitoring screen condensed by Fang Huairan with mana in the mirror.

After teleporting out, Fang Huairan's figure moved, left the bookshelf, landed on the aisle, waited quietly for a long time, and found that everything in the tower was as usual.

As for going out, then wait for the two of them to finish checking it, and then think of hiding it in the newly borrowed book of the confused half-demon and mixing it out.

Fang Huairan looked around and found that he was on the first floor, and there was no one else in the tower except for the two half-demons on duty during the foundation building period, and the four half-demons who were looking for classics on the shelves.

It seems that this floor should be the place to collect the classics of the Demon Clan that did not transform into a shape during the foundation building and the Dan period, and glanced at the spiral staircase located in the center of the library tower, Fang Huairan's body moved, and he fled towards it lightly.

Walking up the spiral staircase to the second floor, Fang Huairan was overjoyed, there was no demon clan on this floor, and when he escaped to a bookshelf, Fang Huairan checked the introduction of the various classics that were banned.

After looking at it for a while, Fang Huairan found that this layer was also a place to collect the classics that could be used during the foundation building period and the knot.

Back on the stairs, Fang Huairan continued to climb up, until he climbed to the fourth floor, Fang Huairan looked happy, this floor is the collection of classics for the Yuan Infant Monk.

Fang Huairan looked left and right, but still didn't find any demons, so he breathed a sigh of relief in his heart and began to look for the bookshelves one by one.

After checking the fourth floor, the two went to the fifth to ninth floors, and it took more than two days for Fang Huairan to finally check all the four to ninth floors of the entire library tower.

What made Fang Huairan depressed was that this library tower mainly collected books on refining tools, talisman making, etc., and classics such as supernatural powers and exercises were obviously not in this library tower.
