Fang Zhuo left Yun Rong behind and let her lurk, carefully observing the number of demon rats and the rules of their activities. The main thing is to observe the mystery of the rat king and the bluestone.

Knowing that he was winning all battles, Fang Zhuo needed to know enough about this group of demon rats now.

If it weren't for that mysterious bluestone, Fang Zhuo could directly pretend to go down and explore, and then report what he saw to the Bitter Sword Sect. This group of demon rats themselves is not something that a few disciples in the Qi cultivation period can deal with.

However, it is now clear that there is a mystery to that piece of bluestone. Fang Zhuo even suspected that it was very likely that this group of huge demon rats had become so huge because of the benefits they had gained from this bluestone!

If that's the case, the things in this bluestone are too important.

Since Fang Zhuo had decided to obtain the bluestone, it meant that he would face this group of demon rats alone. Obviously, this is a big challenge.

As a scholar, what Fang Zhuo is best at is thinking. What he has to do now is to grasp all the strengths and weaknesses of the demon rat, and use his most powerful advantage to target the biggest disadvantage of the demon rat.

Between the good and the bad, there is a chance to win.

Compared to Zu Tong, Fang Zhuo believed that this rat king must be inferior. After all, the intelligence of demon rats is far inferior to that of humans. In battle, once the strength cannot be crushed, wisdom becomes the biggest winning weight.

However, even so, a seriously injured Ancestral Bronze would still need Fang Zhuo, Wind Thunder, Silver Bat and his endless means to resist it.

Fang Zhuo really scratched his head.

Next, Fang Zhuo's days began to get busy.

First, he pretended to go down the mine for two days, and then announced that he had found the trace of the monster. Then, after two more days, he announced that he could start work.

Fang Zhuo found all the passages leading to the mine with the demon rats, and then laid several phantom arrays at the entrance of each passage. These formations can at least block those low-level demon rats.

The demon rat did not launch a large-scale attack on humans, which means that the miners who disappeared before may only have happened to encounter the demon rat that was preying on it, or even launched an attack on it. From the current point of view, the main food of this group of demon rats is still minerals, and occasionally hunting other demon beasts is also to obtain more powerful power.

Human beings, ordinary people who do not have spiritual power in their bodies, have no attraction to them.

Fang Zhuo carved out several areas in the mine and ordered the miners to stay away from them. Under the urging of Gu Chengshan and several people, the panicked miners cautiously began to resume work.

"The demon beasts below are not easy to deal with, I need to prepare. Nothing special these days, don't bother me. ”

Dropping such a sentence, Fang Zhuo began to retreat.

Gu Chengshan and the others had nothing to do with him, and they were worried about the miners below, so they could only go down to the mine every day to patrol back and forth. However, it is strange to say that as the days passed, nothing strange happened.

Fang Zhuo was in retreat for twelve days this time. With Bigu Dan, he is no longer afraid of starvation.

This time, he concentrated on drawing talismans and refining the array disk.

The jade slip he had received from Fan Dongliu during this time had been of great help to Fang Zhuo, and after refining the basic part of it, Fang Zhuo had even been able to comprehend a lot of the mid-to-high-level talisman knowledge he had memorized from the jade slip of the Golden Rune Gate Jin Dan master.

What made Fang Zhuo happiest was that the Golden Rune Stone Man had the ring on his finger, and he had finally researched a little bit of fame. Now it was basically clear to him that the complex rune array in the ring was actually two nested formations. One of them was in charge of the siege, the other in charge of killing. As for the principle, we are still exploring.

With Fang Zhuo's current strength, a large formation that was enough to trap a second-level mutant demon beast in a short period of time, he couldn't successfully arrange it all at once, let alone condense and engrave it on a formation disk. However, the inheritance that Fang Zhuo had received was only a general outline of the runes, and there was no fixed thinking and the influence of his master's preferences, so his thinking was completely different from other talismans.

After Fang Zhuo thought about it for a while, he definitely took apart a formation and carved it on several small array plates. In this way, it not only solved the problem that he could not lay out such a large array at one time, but also solved the problem that he could not refine the formation into a formation disk.

Usually, the setting of the large array must have the array eye as the cardinal, and then it will be supplemented by a series of array flags, array piles, array disks, and so on. But Fang Zhuo's decentralized design is completely different. Twelve small jade plates were carved by him into a part of the talisman array. All these disks need to be placed in the right place, and then one of them is activated, and the others will echo. The twelve array disks were connected as one, forming a large rune array. There's no need to preset the array eye here.

To solve the problem of the formation eye, Fang Zhuo also took a lot of brains. In the end, he removed some of the central runes in the rune array, and he was done. As a result, the mobility of this rune has increased greatly, but its power has decreased considerably. Moreover, the rune array loses the support of the array eye, and the power becomes unadjustable, unlike the normal rune array, which only needs to be infused with spiritual power like the array eye to change the operation of the rune array.

However, Fang Zhuo was still very confident in his rune array. How can it be simple to find out the thick earth formation found in the general outline of the talisman?

Having prepared the formation plate of the Thick Earth Formation and a large number of talismans, Fang Zhuo did not start to act. He still needs a lot of things.

His strengths, in addition to talismans and formations, are also a huge body and a strong flesh + body.

This huge amount of power cannot be wasted.

Fang Zhuo is out of the customs.

Gu Chengshan is in a much better mood these days. For nothing else, a few of them had already discovered the formation set up by Fang Zhuo at the entrance of the demon rat. These phantom arrays don't have any attack power, but they are extremely powerful and powerful.

With the blocking of these formations, the problem has indeed been solved temporarily. However, as Fang Zhuo retreated day by day, Gu Chengshan's heart slowly became restless again.

Those demon beasts can't enter through these passages, won't they dig out other entrances? In short, if you don't solve the demon beasts in the cave for a day, this crisis will always exist.

Finally, on this day, the mysterious inner disciple came out.

Gu Chengshan hurried over with his two junior disciples, wanting to see what means this inner disciple had researched to deal with the underground demon beasts, who knew that as soon as they met, Fang Zhuo once again ushered in a slap from Fang Zhuo.

"I'm halfway out of the shed to get something, so don't bother me if there's nothing to do during this time. ”
