"Sister, let's try it, what will be in this building?" Ling Shaofeng found that when his aura was hidden, the puppet at the door of the building would not stop him.

And the five third-level martial master puppets only held on to a few moves in front of Ling Mingyue, and these puppet teams that were broken up by Ling Mingyue then turned into patrol teams, increasing the difficulty for others to explore the secret realm.

"Squeak......

The siblings pushed the door into the building and found that it was a refining room, but it was already covered with dust, and there were some things scattered on the ground, but there was nothing valuable.

The two rummaged around for a while, and finally found a half-long knife without a tip in the corner of the wall, only the handle and a half-meter-long blade remained, which looked like a waste knife.

However, Ling Shaofeng inadvertently kicked a piece of metal, which just hit the broken knife, and silently, the piece of metal was broken, which made Ling Shaofeng feel a little surprised.

He picked up the broken knife and shook it, and the dust on it fell in a trickle, revealing its true face, a dark red broken knife, but it was a little heavy.

Ling Shaofeng waved the knife casually and slashed across a stone platform next to him, but he didn't expect the stone platform to break away from it silently, and the place where it was cut was as smooth as a mirror.

Ling Shaofeng immediately realized that this broken knife was unusually sharp, and then he picked up all kinds of weapons and metals scattered next to him to test, and as expected, the broken knife easily broke everything, without even making a sound.

"It seems that this broken knife is not simple, look for it and see if there is another half?" Ling Mingyue said in surprise.

However, the two sisters and brothers searched everywhere, and they couldn't help but feel a little regretful because they didn't find the other half of the truncated knife, but Ling Shaofeng thought about it, it was also a kind of luck to be able to get this half truncated knife, if it was unexpected, it might be a bit of a disaster.

What he liked the most was that this knife was silent when it was used, and if he used it when he was hiding his breath, it should be the most suitable weapon.

"Let's go, change the next place, let's see if we can explore all the buildings that haven't been explored." Ling Shaofeng said to his sister.

Subsequently, they explored more than a dozen buildings, obtained a large number of elixirs, excellent weapons, and came across a practice room where they practiced for three days, as well as some ancient texts and exercises and jade slips.

Unconsciously, it had been a month since they entered the secret realm, and Ling Mingyue's sister and brother had already explored the range outside the core area and came to a position of 1,500 meters, and apart from them, the other people's teams could not rush up at all.

"Sister, have those martial arts powerhouses who entered the secret realm in the past ever entered the core area? Otherwise, how could they find the spirit stone? Ling Shaofeng asked with some confusion.

"The spirit stone they found was not found in the core area, but in this periphery, but the chances of finding it are getting fewer and fewer, it should be that the spirit stone in this periphery has been looted by the people in front." Ling Mingyue shook her head and said.

"In this way, we must enter within two hundred meters of the core area, and the guardian puppets here are all fifth-level and sixth-level martial arts strength, if there are too many of them, I'm afraid that only you, sister, will be able to get out of the way, no wonder the school pins its hopes on you." Ling Shaofeng nodded and said.

"Now that I've come here, I also hope to be able to gain more, although the spirit stone is not useful to us at the moment, but if we can find more, the school will reward us with more resources, so we have to enter the core area to search anyway.

Moreover, no one has ever entered the core area, and all the opportunities inside should be there, so if we can seize the opportunity, maybe we can upgrade the cultivation to another two levels. Ling Mingyue looked at the core area and said.

"Also, if there is also that kind of practice room in the core area, the heaven and earth aura inside must be more sufficient, maybe I can cultivate to the peak of a ninth-level martial artist, and sister, you can also cultivate to a high-level martial artist as soon as possible." Ling Shaofeng said excitedly.

The two siblings rested for a day at the 1,500-meter position, and then stepped into the core area, because there was a layer of fog between the 1,500-meter position and the core area, so after they entered the core area, the people outside lost their figures, and no one knew what it was like inside.

After Ling Shaofeng entered the core area, he found that he and his sister had reached the top of a mountain peak, and there were only a few exquisite small buildings in front of them, surrounded by gurgling water, mist, and abundant aura.

"This is the core area of the secret realm, it should have been the place where the most core powerhouse of this sect used to live, right?" The two of them stood still and did not move, but first looked at their surroundings.

"Well, the biggest benefit left by this sect should also be here, but I don't know if we can get it?" Ling Shaofeng said with some excitement.

After pausing for a while, the two slowly walked forward, and when they came to a building, a puppet appeared in front of them in an instant, but unlike the puppet outside, its appearance was exactly the same as that of a human, and it was not a puppet at all.

"Be careful, I feel that this puppet is a little different." Ling Mingyue's brows furrowed, and she whispered to Ling Shaofeng.

"Sister, I'm fine, let me try first." Ling Shaofeng then changed the aura on his body, and soon it became the same as the aura on the puppet's body, and the puppet really stopped looking at him.

"Choking ......"

When Ling Mingyue approached, the puppet in front of him actually took the initiative to draw his sword and attacked towards Ling Mingyue, although it was a puppet, it was only a sixth-level martial artist cultivator, but it was proficient in the swordsmanship of the Consummation Realm, so its strength was very strong.

"Ding......

Ling Mingyue immediately unleashed her sword momentum and fought with the puppet, she found that the puppet's swordsmanship was very subtle, and there was a lot to learn, so she observed the opponent's swordsmanship while fighting.

Ling Mingyue could use Zhongcheng's sword momentum to his heart's content here, so he was able to suppress the sword puppet battle, so he was able to distract himself from observing the opponent's sword technique and learn many subtleties from it.

"Ding......

Ling Shaofeng watched from the side, he believed that his sister's strength was above the sword puppet, but his sister didn't win quickly, there must be her reason, so he didn't worry, but sat down to practice.

"Choking ......"

Finally, half an hour later, Ling Mingyue slashed the sword puppet with a sword, and the sword puppet also dissipated like the previous puppets, and the small building in front of them became an undefended treasure trove in front of them.

The two of them entered the small building and found that there were many pills stored inside, the most common ones were the Guiyuan Pills practiced by martial artists, and there were also a large number of Lingyuan Pills practiced by martial artists, and even the Jingyuan Pills needed by great grandmasters to practice.

"Brother Xiao, we have made a fortune, there are 100 Guiyuan Pills, 200 Lingyuan Pills, and even 50 Jingyuan Pills, this is the pill that the Great Grandmaster needs to cultivate." Even Ling Mingyue was extremely excited.
