Entering the cave and walking through a long passage, Tang Zheng saw two huge stone doors appear in front of him.

The stone gate was immersed in a long and desolate atmosphere, which brought Tang Zheng an inexplicable heavy feeling.

It took a while for Tang Zheng to get out of this emotion, and he was about to push open the stone door when he suddenly noticed that something was wrong.

I heard the strange sound of swishing, and some black crossbow arrows had been shot from the oblique thorns. These crossbow arrows looked ordinary, but at that moment, Tang Zheng still quickly dodged them, and did not let the crossbow arrows stain the slightest.

The crossbow bolts were fired to the ground, and there was no earth-shattering change.

But at that moment, Tang Zheng still felt a strong aura of death from these crossbow arrows.

That's the power of destruction.

These crossbow arrows are endowed with the Dao of Destruction, of course they are not Dao soldiers, they can only exert an effect once, but even if it is the explosion of that moment, the power is by no means inferior to a Dao of Destruction.

Tang Zheng never thought that the Great Dao could be used like this, let alone that this trap would be so simple and so tricky. If it were an ordinary person, in the face of this seemingly ordinary crossbow arrow, maybe it would be directly lucky to bounce off, and the result would be miserable. If it weren't for the fact that Tang Zheng was also proficient in the way of destruction, it would not be easy to find the trick on it.

Just after Tang Zheng discovered the problem, the destructive power on the arrow had disappeared. If you don't find it at first, you won't find it later.

At this time, when I looked at the door, it was still closed.

Tang Zheng didn't open the door, but looked around and sneered: "It turns out that there is a soldier armor formation here. ”

This armor formation is not a strange formation, and its power is average, but the disguise is extremely good, and with the complement of Dao power, it has become a strange array, a half-hung Dao array.

However, the small array is only a small array after all, Tang Zheng easily found out the key, and at this moment, he directly punched it, and when he heard the bang, the eyes suddenly opened up, and the two stone doors had disappeared without a trace, and instead of them, there was a stone room.

Tang Zheng knew that the stone gate before was an illusion, and the stone room at this moment was real.

At this moment, there is a stone bed in this stone room, and there is a man in a Taoist robe sitting on the stone bed, who looks like a fairy wind and bones, which startled Tang Zheng at first glance, and then looked at it to find that he had already died for many years. I don't know what the method is, so I don't return to the ruins, but I still maintain the same appearance before my death.

There are also a few words engraved below the man: "Wuyuan's hometown, don't disturb, what you leave in front of you, take it yourself." ”

In addition to these sixteen words, it is a jade plate.

There are several things placed in the jade plate, namely a booklet, a jade mirror, and a mustard seed bag.

Tang Zheng opened the booklet and looked at it, and found that it was a book of the Five Elements Dao, and all the discussions were the essence of the Five Elements. Although the record is not the root of the avenue, but the words are exquisite, expounding the root of things, exhausting the mysteries of the universe, the more Tang Zheng looks, the more frightened he feels, some of the problems that he once did not understand at this moment are suddenly solved, and he immediately knows that he has a treasure.

This Dao book will not immediately improve his strength, but it will undoubtedly greatly improve his Five Elements Dao.

To a certain extent, it is like the soldier's formula, preaching through the law, but it is inferior to the soldier's word. The word for war is to pass down the Dao method in the form of magic, although it cannot fully exert the power of the Dao of War, but at least it can condense the emperor's blade into an immortal divine soldier. This book of the Five Elements Dao can't do this, but can only explain its meaning, so that the cultivator can feel and comprehend it more easily, and finally realize what he has to rely on. Despite this, it is also extraordinary to be able to do this, and these Five Origin Dao Monarchs are not idle.

As for the jade mirror, it was the pivotal key to the operation of the formation. As soon as Tang Zheng took the jade mirror in his hand, he saw the situation of the entire valley outside, and saw that it was dark to the Flowing Wind and Fire Tianzun and others, and of course, he also saw Yi Yi Xu Miaoran and them who were still in a hard battle.

Tang Zheng only studied it a little to know the usage of this thing, and at this moment, he pressed it lightly, and saw that the ants, spiders, scorpions and other things that were still besieging everyone before had been pushed away.

Xu Miaoran and the others were fighting to the end, but when they saw that these insects had retreated, they were all stunned for a while.

Still Yiyi smiled: "It's my brother, he has found the hub." ”

But it was Tang Zheng who passed the word to her, and everyone breathed a sigh of relief.

At the same time, Mu Si ordered Huo Tianzun and the others to fall into bad luck, and they saw that there were huge insects everywhere, and the three of them couldn't kill them all. Rao is their identity as an earth immortal, and they are also trapped in this vast ocean and cannot extricate themselves.

It's a pity that the Douzhuan Dust Array itself does not understand the killer, and Tang Zheng can only lead to the attack of ten thousand insects, but there are no other methods. It's still too difficult to kill the Earth Immortals with these bugs alone. Fortunately, Tang Zhengben didn't expect this, and it was enough for him to consume some of the immortal qi of the three people.

The other party is recovering, the other party is consuming, and the ultimate winner will only be himself.

This jade mirror is not only the hub for controlling the Dou Zhuan Dust Array, but it is also a treasure of the Formation Dao, which is much better than Tang Zheng's crystal ball, so Tang Zheng unceremoniously put it away and went to open the mustard seed bag.

The first thing that catches your eye is the white jade-like stones.

"Immortal Stone?" Tang Zheng's eyes immediately lit up.

Cultivators have spirit stones to charge energy, thinking that they consume, and immortals also have fairy stones, which are more powerful than spirit stones. It can not only be used to arrange immortal arrays and refine immortal pills, but also can be used to assist cultivation and refine immortal yuan.

However, this immortal stone was used in ancient times, and since ancient times, the veins have been cut off, and there are fewer and fewer of them, and even immortals are rare to find this thing. Tang Zheng had seen a few immortal stones from Yun Tianlan, but he kept them as treasures, and he didn't even give them a second look, saying that they were used to recover during the battle.

Unexpectedly, this mustard seed bag is now full of a large number of immortal stones, which makes Tang Zheng very excited.

With this thing, his success rate in attacking Sendai is higher. After all, what Okamidai needs is a lot of immortal energy, and immortal stones can provide just that.

In addition to the immortal stones, there were also some pills, classics, three divine weapons and some relatively rare materials in the bag.

Those pills are all elixirs that can still be used in the Sendai Realm, and even if they are for Xu Miaoran to do research, they are valuable. In the classics, several quite powerful immortal methods are recorded, but the current Tang Tribulation can't learn it, and the three divine weapons are relatively average, but Tang Tribulation doesn't care about it.

It was those materials that made Tang Zheng's eyes shine.

Because these materials combined with the Five Elements Dao Book, Tang Zheng found a way to improve himself now.
