For the safety of his own life, it is completely worth spending money or something, but Zheng Yichen knows some of the principles of the light explosion, and the people here don't know it yet, of course, they have also studied some relevant information, but they don't have a full understanding of the substantive strength of the light explosion, so that there are some operations that Zheng Yichen thinks can work.

Needless to say, when I haven't tested it, I want to give it a try, and the result is good, the light explosion has no damage to this at all, which makes some casters on the scene a little headache, and the power of those light explosions is really excessive, and the result is this ...... Well, it doesn't work, and they have to think of something else.

Start from somewhere else, such as those places that have already triggered a light explosion, since it is a trap, after stepping on the trap, there will be no trap, right? The idea is very good, the reality is still skinny, and under Zheng Yichen's gaze, nothing else good has happened in that place except for triggering a new round of light explosion......

Traps are still traps and don't go away with the number of times they are used.

The reason why these people are working tirelessly to do the corresponding tests, in addition to thinking that after the trap is consumed, they can play the corresponding follow-up operations, the main problem is that this treasure house is too confusing, if you survey from other places, you can survey that there is a huge 'space' below, and there is a super strong outer barrier, and above those outer layers are magic traps that produce light explosions, and the specific depth is thirty meters underground.

This depth is nothing in a world with magical powers, and a spellcaster can surely make a suitable hole by digging a hole...... This is where miscalculations come in.

The walls of the treasure house are very thick, this is normal, the key is that this treasure house is not a normal wall, Zheng Yichen thinks that thing is a cement lump, a cement lump full of traps, and there may be enough energy sealed inside, specifically to continuously cause light explosions, so that the young people of the head iron can feel the cruelty of what is called ancient creatures.

The current explorers are divided into two categories, one is still obsessed with opening holes in other aspects, and the other is Zheng Yichen who wants to enter from the main entrance in a dignified manner.

When it comes to the main entrance, it is inevitable that it will involve the living area, mainly because the purple robe that Zheng Yichen took out has played a good effect, the strength of the purple robe is not high, but it can withstand the crushing of the hole, obviously it is not that the hole cannot crush the purple robe, but that the hole is merciful, what is the reason, it must be directly related to the nature of the purple robe.

"Speaking of which, you have been studying this machine for so long, you should have gained a little bit anyway, how can you get a higher grade purple robe, or is it a more top-level one?" Zheng Yichen asked, the spellcaster here was silent, the research results are indeed there, but they will definitely not easily tell this dragon.

"Okay, you remember, if you make any good discoveries in the future, don't expect me to say it casually!" Zheng Yichen, who was excluded, was fearless, this group of people did this, then he would not have any psychological pressure to continue to slaughter next time, his tone was like this, after the caster here hesitated for a moment, he hurriedly contacted his superiors, and soon had a reply, revealing some information to Zheng Yichen.

This machine can be used casually, but if you want to make a higher quality purple robe, in addition to the material, there is also a limitation...... Enter the password.

That's right, it's to enter the password, they found a metal plate on the machine, and the metal plate will reflect every time the machine starts, and then after paying attention to it, they found some corresponding ways, the metal plate is the password input in the form of the otherworld, of course, this password is not a number or a word, but a pattern similar to the magic array, so the casters in charge of the research investigated a large number of patterns about the ruins.

As long as it is the pattern in the ruins, including the patterns in some rooms in the living area, it has been tried, although more than ninety percent are useless, but the remaining little is really useful, so that they can successfully get a better quality purple robe, this matter is a unique secret, not let many people know, including Zheng Yichen, let alone make a record in the alliance hall, this is mainly thinking that after breaking the protection of the library in the future, I will learn more relevant pattern records from there.

"Okay, I've made a note of you, and the next time I have a meeting that belongs to me, you're free. Zheng Yichen said with a smile, it may be a bit of a loss for him to say this, but when he thinks of the harvest after that, it doesn't matter if he loses or not, the main thing is that he wants to make friends with this group of people, and there is nothing wrong with him suffering some losses for the rest.

Pattern...... Zheng Yichen immediately sent this message to the witch group, and Loriss told Yilin about the things in the group by the way, and the next thing was simple, his idea was also very direct, the library had already been hollowed out by him, and all the records over there were there, flip through the books to find some patterns that might be useful, and he just need to make some more attempts here.

Ireen was busy over there, and Zheng Yichen was holding a lot of materials, constantly operating the machine, seeing that he was just trying, and he didn't look like he was holding a hammer wrench to disassemble this thing, and the caster next to him didn't see it, only when Zheng Yichen was operating on the metal plate, they would pay extra attention to it, and silently write down Zheng Yichen's graffiti pattern on it.

But after looking at it for a while, he fell silent, what kind of thing is the chicken pecking at the rice map? Will he use things as a drawing board? Although the cost of the lowest-level purple robe is not high, only a few dozen gold coins of materials can be done, but those patterns are not permanent, so it is crazy to waste this dragon?

Noticing the eyes of the spellcasters, Zheng Yichen muttered, "Anyway, it's not my money that is spent." ”

"......?" They were still a little puzzled at first, and then they realized what was going on, thinking about the copy building over there,, it was indeed not the dragon's money that was spent, they felt a little bit of helplessness and helplessness in their hearts, watching Zheng Yichen continue to toss like this, although he occasionally talked about some pictures of pit people, but most of the drawings drawn were normal, normal and a bit hell, the magic array of the fireball technique, the magic array of the water archery technique, and the higher level magic could also be drawn out of high-level magic such as fire explosion.

Looking at Zheng Yichen's appearance, he even wanted to draw a few high-level magic arrays on it, what is this, right? It's just that Zheng Yichen didn't destroy it, and they also watched all kinds of purple robes of different qualities appear around this dragon, not to mention, if there are more magic arrays drawn, they can really get some 'passwords', although the quality of most of the purple robes is very low, but the quality of a small part of the purple robes has obviously improved a lot, which can be seen from the appearance.

Is this really good??

Those spellcasters were a little stunned, Zheng Yichen directly ignored the stunned casters, since this metal plate changes its form according to the picture, there is really nothing to say, the patterns on the edge can affect the quality of the purple robe, compared to painting some patterns blindly, isn't it better to directly use ready-made?

Aren't all kinds of magic arrays the most ideal patterns? Those magic arrays are still regular, how nonsense is the password of this place, and it can also be used against some of the magic array patterns, right? Even if it is a little bit, it is better than the level of scribbling, Zheng Yichen has tested it many times, with a general estimate, the matching of patterns, each line must have a matching lower limit, and a little touch will definitely not work.

It is necessary to ensure that the curvature and length of a certain line can only really play a role, so say: "You have researched a lot of passwords, right?"

"This is top secret!" Those spellcasters said simply, the password has indeed been studied, although it is a stupid method, it is very effective, simply put, it is to see which pattern works very well, and then keep holding this pattern for testing, and then delete part of the pattern, if it is deleted will affect the quality of the purple robe, then the deleted part must involve the password, add it back, and continue to delete other places.

The follow-up streamlining of the entire pattern, until there is no streamlined part, start a new filling, if the filling and part enhances the performance of the purple robe, then it must be the right one, leave the right part, and continue to fill on this basis, until there is no improved part, with this operation, they successfully made quite good results, but the time and price paid are very high, and it has a more important role in the exploration of the dungeon, and even they feel that this is the necessary key to break through the central area.

After the quality of the purple robe is high to a certain level, maybe when it passes through the central passage, those dangerous spatial rifts will take the initiative to avoid it.

"Oh no, I tested it myself. Zheng Yichen pursed his lips, and drew a magic array in front of him, and the corner of the caster's mouth next to him couldn't help twitching, this dragon is really the kind of little temper that is circulating, and his magic array directly made a mosaic of the metal plate, which fundamentally made them unable to observe the pattern drawn by Zheng Yichen in the future, but this is also within the rules, if it is replaced by their people, if this dragon is here, it will also make a similar operation.

After playing the mosaic, Zheng Yichen began to test it intently, and Ireen sorted out some patterns that were suspected of being passwords for him.

There are a lot of books in the library, although the things in them will not directly mention the core important information, but some information can still be analyzed and excavated through the record of the edge ball, or the meaning of the connotation, Zheng Yichen's discovery here gave Yilin some new inspiration, and the books in the library do have books involving certain patterns.

“...... Have you noticed that the purple robe made by this dragon has more detailed patterns. A spellcaster watched Zheng Yichen stay in this place for almost a day, and after he hadn't left, he looked at the purple robes around him idlely, and couldn't help but show a look of surprise, Zheng Yichen obviously also used the stupid methods used by the forces behind them.

Catch one of the best patterns and fix them to death.

"I found out a long time ago, and I made a report, but this dragon has this illusion, and we can't see what the pattern is. The lead caster shook his head, and said helplessly, that is, this kind of covering, directly let the people behind them not plan to come over and mix a hand, this dragon was very good before, and it will not get any benefit to come over and mix a hand in a hurry, but it will be recorded in a small book by him, and the gains outweigh the losses.

Besides, the biggest role of the purple robe at present is to enter and exit the dungeon, as for the highest-level purple robe, the code made by ancient creatures, how can it be so easy to crack, just kidding.

Zheng Yichen looked at the metal plate in front of him a little numbly, the fingers of the reappearance were almost rubbing bald skin, the entire metal plate was still as bright as new, and the quality of the purple robe was getting higher and higher, just looking at the thousands of purple robes piled up in the carry-on space, it was a little worrying, this thing is said to be magic equipment...... Not really, they're just things with specific protection.

It's like eating the magic of a big fireball head-on, damn it will still die, don't expect this thing to play a big role, so no matter how many of these purple robes are, it's not out of some special environment, it's still a waste product, and he thinks about recycling it later.

At present, this stupid way of cracking the code is really burning money, and the income is good, Zheng Yichen now gets the quality of the purple robe, which has surpassed the highest quality purple robes he has ever seen, although the color has not changed much, but the feeling in his hand is obviously different.

"That's all for today. Yilin said in the witch group, and rarely sent a relieved emoji, what Zheng Yichen does is to be like a tool man, just paint and paint here, she has to use a lot of energy to analyze the patterns and information learned from ancient knowledge, disassemble it sufficiently, and then make subtle adjustments according to Zheng Yichen's feedback, etc., which also combines a large number of other types of information.

For example, some lines on the door of the treasure house, etc., this is not a classic work in reality, such as when you encounter the entrance to the treasure house of some ruins, you can easily get the door with the pattern of the ruins logo, and the important treasure house can be easily opened.

If it's really that simple, others won't have to die or live to explore the ruins in various ways, in short, when you encounter that type of ruins, while thinking about taking advantage, think about whether this is intentional or not, whether there is really a treasure waiting for you when you go in, not some unknown horror.

"Okay, then I'll go to the treasure house and test the water first. Zheng Yichen looked at a purple robe with obvious quality in his hand and said, he still had to prepare to start from that hole, after a poke and stab test, he had already figured out the depth of that hole...... That is, the depth of about the length of the adult's middle finger, which is very shallow.
