The arrow in Tianyou's hand is not a metal product, it looks cold and shining, but it is very light to start, and the surface feeling is slightly cool, not the coldness of metal.

"It's ...... What are the bones made of?" Tianyou looked uncertain as he held the arrow.

Hu Qingxuan took it, first rubbed it with his hand, and then shook his head and said, "It's a tooth, some kind of monster's tooth." ”

"What youkai have such sharp teeth?"

"Many, as long as the demon power is strong enough, the teeth of any demon clan can be so sharp. Hu Niu said and deliberately opened her mouth and nodded her little tiger teeth, "For example, my teeth are very powerful, even if it is a finger thick iron armor, I can easily bite through." ”

Hu Qingxuan shook his head and said: "It doesn't have to be high enough, there are also some demon clans who are born with better teeth, maybe the cultivation level is still at the level of demon beasts, and their teeth are already more powerful than the big demons." ”

"What about this one?" asked Tianyou.

Hu Qingxuan thought for a while and said, "It should also be the teeth of some kind of low-level monster." Before the Battle of the Catastrophe, although there were many demon races, they were the same for any race, and the more powerful they were, the fewer they were. The number of demon clans above the level of big demons must not be large, and their status is relatively high. Even if the teeth of our demon clan can be regenerated, generally no one will have nothing to do with pulling out their own teeth to polish the arrows. Besides, there is no remnant of demonic power on this arrow, obviously not relying on demonic power to sharpen, but is born so hard. ”

I thought I had picked up a treasure, but I didn't expect it to be just a special demon beast tooth, and Tianyou was a little disappointed. But no, no, no. At least the arrow is still of some use. Tianyou's own archery skills are very good, and the compound bow in his hand is also an artifact-like existence, which is still a tabula rasa bow that has not been transformed with refining technology. With this arrow, Tianyou suddenly wanted to upgrade his bow. Of course, the premise is to learn the refining technique well.

Bypassing the copper furnace, which had no research value, Tianyou looked around, and was soon attracted by a pile of broken wood chips by the broken wall. Of course, it wasn't the wood chips that attracted him, but something underneath the wood.

Tianyou's aura was so powerful that it could even be seen directly in his eyes, so any undisguised aura would be discovered by him as long as it flowed. The reason why Tianyou noticed this pile of wood chips just now was because he found a little spiritual light under the pile of wood chips.

walked over, squatted down, and didn't dare to reach out directly, but used the emperor sword to pick up the rotten wood on it.

These timbers should have been extraordinary back then, but after thousands of years, the preservation environment is so bad, and even the best wood has long since decayed and rotted. Tianyou found that the seemingly piece of wood could not be picked apart, and as long as it touched it, it would immediately shatter into a pile of black soil, and it was completely powerless.

After thinking about it, Tianyou simply stopped caring about the broken wood that was in the way above, and directly used the emperor sword to reach out to the thing below that emitted spiritual light.

The wood chips on the top did not have any blocking effect with Ben, and the scabbard on the outside of the Emperor Sword easily touched the thing that emitted aura below.

It doesn't feel like a chunky item. Tianyou probed for a moment, and found that it was most likely a piece of paper, so he simply picked it out of the pile of black rotten wood powder.

The pile of rotten wood had long since turned into a pile of black soil after some tossing by God, but the items buried under it were not stained with the slightest filth. As soon as it was picked out of the black mud-like fragments, a faint golden light flashed.

"It's ...... Rune paper?"

Tianyou turned out from under the broken wood is clearly a very common rune paper, and there are runes outlined by cinnabar red pen on it, plus the spiritual light shining in Tianyou's eyes, it can be concluded that this is a rune paper that is still valid today.

It is hard to imagine that a rune paper can be preserved in such an environment for thousands of years without any damage, and even the aura on it is not lost. Although I couldn't understand what was drawn like a ghost drawing on it, Tianyou was at least sure that it must be a very precious rune paper.

"Moon Shadow, do you know what this is?"

Tianyou Moon Shadow here should be the most well-informed one, although she may not have surpassed Hu Niu and Hu Qingxuan in terms of level for the time being, but she has an extraordinary identity after all. Even if the memory is not fully recovered after Nirvana, he still knows much more than Hu Niu and Hu Qingxuan. The only problem may be that there are some problems with the continuity of knowledge.

Didn't show up. On the premise of not being sure that the surroundings are absolutely safe, the Moon Shadow will generally not separate from Tianyou. She is the last insurance of God's blessing, if the market is separated, then it may be discovered by others, so as long as it is not certain that a certain safe environment is determined, she will not separate the ontology.

With the help of Tianyou's senses, Moon Shadow can also observe the outside world, she slightly observed the yellow rune paper in Tianyou's hand, and then gave a negative answer.

"No, I haven't seen this kind of talisman, but I can conclude that it is an immortal talisman. The technique on this talisman is something from the fairy gate, but I have never seen it, so I don't know what it does. ”

"Can't you see anything at all?"

"Not really. Moon Shadow hesitated for a moment and replied, "It can be seen that there is a formation about sealing and protection, it should not be a spell used for attacking, but the specific function needs to be tried before we can only know." ”

"Try?" Tianyou was surprised. "How do you try this thing?

"Except for offensive spells, which are mostly one-time use, other types of spells can generally be reused indefinitely as long as they are not mana exhaustion. I don't recognize this talisman, but I'm sure it's not an offensive talisman. ”

"There's got to be a place to post it, too. ”

Hu Qingxuan looked around, and then picked up a wooden stick casually. "Just give it a try with this. ”

Tianyou took the wooden strip, thought about it, and pasted the rune paper in his hand. However, the rune paper, which originally didn't seem to be anything special, was glued to the wooden strip as if it had its own adhesive. But other than that, nothing else has changed.

"This ...... Is it in effect, or is it not in effect?"

Hu Qingxuan was also a little unsure, so he took a closer look, "It doesn't seem to have changed much." However, since the rune paper is glued, it must be effective. ”

Hu Qingxuan is talking about the basic principles of rune paper. As long as the general rune paper is effective, it will inevitably undergo certain changes. For example, spontaneous combustion or self-adsorbation on the surface of something. The rune paper in Tianyou's hand originally had no stickiness on the surface, but when Tianyou pasted it on the wooden strip, the rune paper automatically stuck to it. This shows that the rune paper is indeed effective. However, although the rune paper had taken effect, the wooden strip in Tianyou's hand did not show any change.

Obviously, Hu Qingxuan's previous guess was correct. This rune paper is not an attack type rune paper, but its function is very vague, and even if it has taken effect, there is no change in the slightest. But that's a bit harder. If you can't see the change, you can't determine the function of this rune paper. Although it can also be brought back and let Zhenyuan Shangxian help take a look, for some reason, the battle of the catastrophe seems to have always been a taboo in the hearts of Zhenyuan Shangxian and their "people who have come over". Although there is no explicit rule, people seem to be shy about talking about related things.

In Tianyou's opinion, this rune paper, and even this island, must be related to that catastrophic battle, so if possible, Tianyou tried not to notify Zhenyuan Shangxian. Of course, there is a more obscure reason for the little selfishness of Tianyou.

Zixiao Palace has always regarded itself as the orthodox successor of the Immortal Gate, so it has an aspiration to obtain all kinds of items left by the Heavenly Court in the Battle of the Catastrophe, and even the ruins. In the past thousand years, whenever there are some relics or items from the past that have appeared, Zixiao Palace will find a way to keep them for themselves. A large part of it is not even bought and sold.

Of course, Zixiao Palace still has to be faced. Direct Mingqiang generally won't, but excuses or something, as long as you want to, you can always find it. But more often than not, it relies on coercion, or in a way that oppresses people. After all, within this Divine Continent, there were not many forces that dared to confront Zixiao Palace head-on.

Although the purpose of this rune paper is not clear for the time being, it was finally picked up by Tianyou. Although because he is the disciple of Zixiao Palace, and the head of the sect and other immortals also take care of him, he may not take it back directly, but after all, there is such a possibility. Moreover, Tianyou just found such a rune paper on the island, and it is hard to guarantee that he will not find anything in the future. If it's a report......

This idea only turned around in Tianyou's mind before he put it down. He naturally has selfishness, but if the ruins on this island are really preserved with a large number of items, he obviously can't eat it alone. So after thinking about it, the most profitable way is actually to report it, and then try to use your good performance in the door, collect some things that are useful to you, and then exchange the rest for rewards. This is more advantageous than eating alone.

Once you think it through, you won't have to worry about the rune paper in your hand. If you can't try it, you can take it off and put it away, anyway, just know that the thing is fine.

After putting away the rune paper, he continued to search at the bottom of the pit. God forbid, they soon found another door far from the collapse point.

The door was originally embedded in one side of the building's wall, but because the entire building is slanted, it now looks like a door has been opened in the floor.

Years of burial, combined with the lowest part of the building, caused the door to be filled with mud and all sorts of dead leaves, burying almost the entire door. If it weren't for God's good eyesight and careful searching, he might have ignored the past.

After a lot of effort to clean up the clutter, Tianyou tried to push down the door.

Looking at the wooden door that is not heavy, I don't know if it is because of the blockade of the mechanism or the damage caused by the disrepair. But Tianyou didn't bother to study it. Directly sacrificed the Taiyi sword, brushed twice and cut a wooden door into four pieces, and kicked the whole into the house with one foot.

The broken door fell into the empty room below, and instead of the sound of the floor, there was a sound of water.

Tianyou stretched out his head and looked down, and all the entrance was pitch black muddy water. After years of closure, the underneath has apparently been flooded with rainwater.

Qi Xiaomei looked at the black mud and asked Tianyou, "Do you want to go down?"

"It's all come to this point, how can you retreat because of a little muddy water?" Hu Niu didn't wait for Tianyou to answer and stretched out her hand to the house below, and an ultra-small tornado instantly formed, like a vacuum cleaner whirring out all the stagnant water in the house. After just a sip of tea, the stagnant water under it was drained.

Obviously, the space below is not large, otherwise with this little spell mastered by Hu Niu, it would be impossible to drain the stagnant water so quickly.

Most of the stagnant water was drained, and Tianyou didn't care about the mud below, and reached out to hit the door frame and jumped down.

Disproportionate to the huge hall outside, this side room is very small, about the size of two double beds.

The interior of the house has long been eroded by muddy water, and there are hardly any complete items to be seen, except for a pile of garbage piled up in the lowest corner of the room. Coupled with the mud around that hasn't dried yet, to be honest, it looks more like freshly cleaned sewer sludge.

I don't know how long the mud has been soaked underneath, the taste is really not very good, Tianyou really can't do it, so Hu Qingxuan threw a branch down and rummaged in the mud.

At the top of the table were a few wooden sticks, which were supposed to be attached to something, but now only the roots remained. Carefully took out one, and Tianyou didn't care if it was dirty or not, he directly wiped off a layer of slippery mud with his hands, and looked at the wood material below. Unfortunately, the wood is so rotten that it is almost impossible to identify what it was originally, and it feels like it will crumble as long as it is taken out to dry, in short, it is completely unusable.

Throwing away the useless sticks, Tianyou rummaged through the mud again, and fished out a lump of unidentified metal that had rusted into a single piece. It could be seen that there should have been several pieces of metalwork, but now they are indistinguishable from each other. It all looks like a half-melted piece of metal.

Although it didn't look good, Tianyou still threw this thing up. What can be collected by the Heavenly Palace will definitely not be mortal iron, even if the spiritual power disappears and the rust is serious, but smelting or something is not a difficult thing for Tianyou, maybe this is what kind of rare metal.

Continuing to rummage through the mud, he found several more black balls. This thing looks a bit like a black chicken and white phoenix pill, black and not slippery, soft and greasy, the feel is extremely terrible, and it has excellent elasticity, I don't know what it is.

After thinking about it, I still didn't want to throw it away, so I handed it directly to Hu Qingxuan, and they took it out first.

At this point, the mud is almost turned over. Tianyou continued to try down, and as a result, he pulled out a Taiji-shaped magnet.

This thing is not small, and it looks like a large mooncake in your hand. Although the surface is covered with mud, it can be seen that it is divided into black and white, which happens to be the pattern of yin and yang fish. And God blessed it, and this thing actually broke open. Both fish are made of magnets, and when they are approached, they automatically snap together, and the seams are tightly seamed and extremely precise.

Compared to the metal, this magnet is not damaged at all. There is no spiritual power left on it, and it is not like a magic weapon. However, this workmanship is obviously not an ordinary item, and it should have a certain value. Anyway, it's not big, so Tianyou simply took it out.

That's all that comes out of the mud, and the rest is basically real garbage.

Tianyou crawled out of the room, and Hu Qingxuan and the others had already found clean water to clean the previous things.

The lump of metal was really rusted into a lump, and it couldn't be separated at all, and there was no other possibility than to return to the furnace and refine it.

The black balls turned white after cleaning, and they were extremely pure white, without a little variegation. But this soft feel really can't figure out what the hell it is. At least no one on God's side knows about this thing.

The last magnet is indeed as Tianyou guessed, one black and one white, just two yin and yang fish. However, after washing off the mud on the surface, you can see the lines on it more clearly, the style is in line with the design of Tiangong, and there are four seal characters engraved on the back, which are "Taiyin" and "Chiyang".

The magnet yin-yang fish can be disassembled, the sides are completely symmetrical, and the bond is very tight. The fisheye seems to be some kind of mechanism that can be pressed, but Tianyou has tried it a few times, and nothing seems to have happened.

I don't know what this thing does, but if it's so well made, it won't be useless. Tianyou can only choose to put it away first, and then go back and ask Zhenyuan Shangxian for advice. After all, Zixiao Palace is the relics of the Heavenly Court, and many things have been inherited. Zhenyuan Shangxian is also a master of refining weapons, as long as it is not too out of the way, he can generally recognize it.

This collapsed building has been completely rummaged through by Tianyou, and there is nothing special about it, so they can only continue to explore the depths of the island.

Although it was already certain that the entire island was part of the crashed Heavenly Court, without the maintenance of personnel, a thousand years would be enough to change many things.

God bless them as they continue to move deeper into the island, and most of what they see is a variety of plants. They crawled all over the ground, occupying the rocks, and obscuring the remnants of the buildings beneath them. Without the maintenance of the intelligent race, even the immortal island with certain spiritual power characteristics can only succumb to the power of nature.

The chaotic island has no roads at all, and not even animal trails have been found. The outer areas were occasionally washed by the sea, but as they went deeper, they could only jump between the rocks and trees with good physical strength.

In addition to the wreckage of the fallen buildings, there are many cliffs formed by fractures on the island, of course, the height is not very large, God bless them belong to the kind of level that they can jump directly into. However, it was in such a crack that Tianyou suddenly found something interesting.
