And it's not just made of metal, the walls of the entire inner corridor are carved with different patterns, all of which are in the form of reliefs, but Zhou Ran has passed through the lighting of the internal qi and carefully observed these patterns, but he didn't find any additional content, and it is not like he accidentally saw the words on the black iron gate before, and he felt the same unique sense of loneliness.

The same direct touch of these metal walls with his hands, but he can only feel the touch of metal, not really cold penetrating his heart, that feeling is just an illusion, slowly withdrew his hand, Zhou Ran looked at the patterns on the wall again, after a moment of silence, finally did not make a move to rubbing, wanted to rub all the patterns on the entire wall, the ink and paper he held in his hand were not enough, It is estimated that all of them can only be rubbed two or three square meters, and the patterns in such a small range must not be able to see anything, so Zhou Ran thought for a while and gave up cleanly.

Continue to walk towards the depths of the corridor, Zhou Ran kept observing left and right, the series of flying knife attacks just now really scared him, that level of power, even if it didn't hit his vital point, it could cause him enough trouble, this corridor was weird and dangerous enough, it was not a prudent way to pull that kind of trouble to his side, and it was the wisest choice to avoid those dangers at the beginning.

However, it seems that there will be no more dangerous situations such as flying knives in this corridor at present, Zhou Ran has been walking inside for almost 20 minutes, and he has not encountered any other situations, he has observed left and right on the wall except those patterns, there is nothing else, and he has even stopped several times to carefully observe those patterns.

Because he deliberately staggered the time period, there are subtle differences in the patterns of each section and each period of time, but this difference is very small, and there is no hidden information in the patterns of each part, not like many fantasy works, it will always be said that there are some words and tricks hidden in the patterns in this kind of place.

If it's an ordinary person, it's likely that there will be a mistake in such a situation, but it's impossible for players, players have reconnaissance skills, and reconnaissance skills are indeed no way to view the information of certain items, but don't forget that when your reconnaissance skill level is not high enough, when observing the information of certain items, the panel will also give you an additional hint, that is, your reconnaissance skill level is not enough, please upgrade and then carry out the next reconnaissance or something.

That's right, you really can't see the information, but you can react through this notification, you did see a certain item, but because the level of ability is not enough, so you can't see the details of this item, but now Zhou Ran has been looking left and right for a long time and has not seen any useful information, so he can basically be sure that there is nothing hidden in these patterns.

After walking a short distance, Zhou Ran saw the strange device at the corner of the ceiling and the left wall, which was an octagonal metal cylinder about the same length as his forearm, but obviously two or three times thick.

There is a small hole about 5 cm in diameter at the front end of this metal cylinder, Zhou Ran didn't dare to put his eyes directly in front of the hole, what if a flying knife flew out of this hole? He just put his eyes together, isn't that death?

So he chose to cover himself first, and the left hand of the angry wood King Kong came to the side of the small hole, and his left hand was just revealed a little, and suddenly there was a strange sound of changing from the tissue, and then a flying knife was shot out of the small barrel.

With a distance of less than 20 centimeters between the two sides, Zhou Ran didn't have time to dodge at all, the speed of the flying knife was surprisingly fast, he only felt a sharp pain, and then the flying knife completely penetrated the layer of strong internal qi covering his hand, leaving a shallow wound in the palm of his hand.

It happened that Zhou Ran had a little premonition in advance, and then covered his palm with a very majestic, even terrifying internal qi, otherwise if he used his palm to go up directly, he would be pierced if he suffered such a flying knife.

Unexpectedly, his temporary idea actually saved his left hand's life, Zhou Ran hurriedly withdrew his hand and shook it vigorously, with a look of joy on his face.

Relieved the pain on his left hand, and then Zhou Ran thought about it and stretched out his right hand, but this time the flying knife did not eject out, Zhou Ran showed a little surprise on his face, he hesitated for a while and then withdrew half of his right hand, and then slammed his elbow up, but he didn't expect the elbow to appear in front of the small hole, and another flying knife flew out.

Zhou Ran tried a few times, he found that the degree of discrimination of this flying knife, even the degree of intelligence is quite high, if he put the same part over twice, then it will not be the second time to eject the flying knife, but if he changes it, for example, at the beginning of the palm detection, the second time with the elbow, the third time with the shoulder, the fourth time with a certain weapon, then the flying knife inside, will continue to fly out.

A little strange smacked his lips, this kind of mechanism skill is not something that ordinary people can do, the Heavenly Demon is indeed very strong, whether it is the combat ability or the exercises they practice, it is a very strong level, but he has never heard of the Heavenly Demon will use such a thing as a mechanical technique.

Just kidding, the Heavenly Demon has mastered the top puppet technology among many races, and if there is really any need for battle or other scenarios, then it would be good to use the puppet technology directly.

Whoever gives a not-so-appropriate example, a complex robot with very complex wiring and a little water that can't be used, and a liquid metal robot that can be directly converted into a liquid form, both can do the same thing, and the latter is not very complicated to use, and it is also what you are good at, then you will spend a lot of time studying, need to arrange the cable, need to install batteries, need to charge, need to maintain the backward old robot?

Although this example is not very appropriate, then to put it bluntly, this kind of thing is indeed very strong, but even with the blessing of various true elements or strong energy of internal qi, the effect it can exert is also very obvious compared to the puppet technique, and the two sides are not on the same level at all.
