The group walked over and cleaned up the dead branches and leaves, revealing a pile of rubble, and in the gap of the pile of rubble, there was a silver-gray chest hidden.

"I'll wipe it, isn't it, it's really a treasure chest?"

"That's fine, Storm, you're a god!"

"Wild Picture Treasure Chest, how do you play this?"

"Uncle, does the stalker have a lockpicking skill?" Speaking of it, the big guys are looking at Yi Qingchen expectantly!

"Uh......" Yi Qingchen was stunned, but he didn't try it with his lock-picking skills, but took out a key, which was the one he was rewarded for finally opening the Red Fire Box-

[Master Key]: A magical key that can open any locked item, including mysterious treasure chests, system equipment, etc., with 0/3 times of use and a cooldown of 24 hours......

Yi Qingchen didn't use the lockpicking skill to try, but directly took out a key, which surprised everyone!

There are two types of treasure chests set by the Divine Crown system, one is a fixed refreshed treasure chest, and the other is a random refreshed treasure chest; The former is divided into ordinary treasure chests, bronze treasure chests, silver treasure chests, gold treasure chests and god-level treasure chests, and the fewer times they are opened, the more generous the rewards; Otherwise, you may not get anything.

The latter does not have a clear grade, and the refresh location is not fixed, in other words, it can be refreshed anywhere, and it is often not refreshed again after it is opened, and the rewards are not the same, mostly some special items, strange, and so on.

As for the silver-gray treasure chest that appeared in Yunmeng Guze, Yi Qingchen wasn't sure if it was a silver-level treasure chest, but it definitely wasn't that simple when it appeared on the hidden map.

Therefore, Yi Qingchen didn't dare to try the lock-picking skill, if it was a random treasure chest, or a task treasure chest, if it was damaged, wouldn't it be impossible to try!

"I remember, this key seems to have been opened by the last Red Flame Chest!" Qianqian suddenly remembered the origin of this key.

"Well, it's this key to universal ~ energy, which can open any locked item, including mysterious treasure chests, system equipment, etc.......," Yi Qingchen explained to everyone.

"It's so against the sky, it's really a magic key......"

"Doesn't that mean that the person who holds the key can ignore any lock?"

"That's what it means in theory, but it's a pity ......" Yi Qingchen said embarrassedly, this key definitely lives up to the name of Wan~ Energy, anything that is locked, this is going to touch this key, naturally invincible, but it's a pity, the cooldown time is a bit long, and it also limits the number of times it can be used, otherwise......

"What is this, why can't I understand......" Purgatory Storm and the others puzzled.

"Yes, it's just a wild map treasure chest, why do you still use the almighty ~ key?"

"It's a waste, there is wood and ......"

Obviously, after everyone understands the role of the almighty ~ key, they feel that opening a wild map treasure chest is still a silver-level treasure chest.

"I'm afraid that if you use the unlocking skill, once the unlocking fails, it may damage the treasure chest......" Yi Qingchen didn't explain too much, since the Five Elements Treasure Chest gave the universal ~ key, then the universal ~ key will inevitably come in handy, and this silver-gray treasure chest may not necessarily be a silver-level treasure chest.

What's more, Yi Qingchen is not alarmist, after all, finding a treasure chest in the field map is a small probability event, not to mention that it is in the hidden map, then you must use a specific key.

And Yi Qingchen and his party have gone all the way, all the dropped items, except for gold coins and equipment, and even the materials for forging and sewing have never appeared, let alone a key, so Yi Qingchen took out this universal ~ key!

Yi Qingchen was extremely sure in his heart, this silver-gray treasure chest must be opened with a universal ~ key, and he had also experienced this situation in the mirage secret realm, the only difference was that the key to open the treasure chest at that time was dropped by the boss monster, and it was a specific key to open.

"I agree with the Night Boss!" Gen Shan Xing said abruptly.

"What?" Qianqian couldn't help but be stunned, and found that the person who spoke was Gen Shanxing, who had always been taciturn, but the strength of this beast tamer should not be underestimated.

"What are you kidding...... no one in the tomb was shocked: "Besides, our mission is to find Thor's lost treasure, I think the real use of the almighty ~ key is to open the treasure, not this silver-level treasure chest, in case it ......"

"It's not unreasonable for no one to say, long song, isn't it ......" Demon Venerable Chi You wanted to speak and stopped!

"Uncle, are you ......" Xiao Xiao pulled Ra Yi Qingchen's arm and said: "Even if this treasure chest is opened, it may not be related to the task, not to mention that what we need to look for is the Yunmeng Ruins......

"Eun...... Sister Yao is right! Qianqian nodded and agreed: "Uncle, you don't think that there are ruins hidden in this treasure chest, do you?" ”

"Ahsan......" Sirius pulled back Genshan Star in time, and said with a smile: "It's good that this brother has Changge to decide for himself, hehe......"

"Brother Tian, I'm serious...... Gen Shanxing said again, "No one knows better than me why the Night Boss did this!" ”

"Uh......"

"Boss, you're not doing it, are you?" No one in the tomb was suspicious.

"Is your skin itchy again?" Yi Qingchen snorted coldly: "I still think I should give it a try!" ”

"Why?" Demon Venerable Chiyou hesitated.

"Have you noticed, the people of the Proud World Righteous Guild are just in the opposite direction from which we came......" Yi Qingchen asked without answering.

"Boss, doesn't that mean anything?" No one in the tomb was surprised!

"Uh......" Yi Qingchen smiled bitterly and continued: "Then we might as well make a bold guess, the entire Yunmeng Guze can be regarded as a long and narrow river, in which whether it is water or jungle, it is naturally downstream, then it is not difficult to explain why the two sides are facing each other......

"You mean, where we entered Yunmeng Guze, one was in the upper reaches of the river and the other was in the lower reaches of the river?"

"Well, it can be understood like this......" Yi Qingchen said firmly: "The two parties met here, and it was obvious that they didn't find any clues about the Yunmeng Ruins, so they ......"

"So, this silver-gray treasure chest hidden in the pile of rubble must be related to the Yunmeng Ruins?" Qianqian took over.

"That's right, that's my reason!"

"What if the topographic map of Yunmeng Guze is not a long and narrow area?" Qing Yu scorched and questioned!

"This is even better...... Yi Qingchen said with great confidence: "Now that there is no one and there is still a storm, one of you two is looking in the direction of the water, and the other is looking in the opposite direction, you should have something to gain!" ”

"Boss, isn't it, it's really so mysterious?" No one in the tomb is suspicious!

"If you don't try it, you will know, I also want to see if it is really like what the night boss guessed!" The firestorm immediately rushed in the direction of the waters!

……

About half an hour later, the two of them reappeared in front of everyone, and they looked incredulous!

"How?" Qianqian couldn't help but ask!

"Say it quickly, talk about it ......"

"Night Boss, I'm convinced!" Purgatory Storm said bluntly!

No one in the tomb admired the five-body throwing to the ground, and said with a smile: "Boss, you are awesome!" ”

"What's the situation, you say, don't sell the guanzi...... Xiao Xiao asked a little anxiously, but looking at the expressions of the two people in the tomb and the Purgatory Storm, he couldn't help but lose his voice: "You won't really let the uncle cover it, right?" ”

"Uh......" Yi Qingchen is quite unambiguous, what is Meng, you are Meng, I will take a look. But he didn't dare to say this, otherwise there would definitely be no good fruit to eat.

"The Night Boss is really a god, I ran forward for almost ten minutes, and then I was blocked by an invisible barrier, but I knew that there was still a long way to go from the water, and I changed several directions, and I couldn't get through......" Purgatory Storm recounted the situation he encountered!

"Uh, me too!" No one in the tomb nodded and said, "Boss, your guess may be right, I think the map we are on should be a very small part of Yunmeng Guze......"

"Hiss......" When everyone heard this, they couldn't help but gasp, and they all looked at Yi Qingchen, hoping that he could explain!

"Well, then it should be right, this isolated area should be the trial map of the mission......" Yi Qingchen said: "The key should be this treasure chest!" ”

"Now that you've found the key to going to the Yunmeng Ruins, what are you waiting for......?"

"Mmmm, so as not to have too many dreams at night, let's hurry up and open the treasure chest!"

"That is, if there are variables, or if another team of people appears, it is not a loss......"

"I can't wait to make the first move......"

……

"Well, then open it, but let's stand back a little bit, in case it is the boss's, then it's ......" Yi Qingchen joked!

"Boss, hurry up, I can't wait to open a boss!"

"That is, if we can open a BOSS, it means that we are going to get rich, quack......"

“……”

Yi Qingchen wanted to make a joke, everyone took it seriously, what kind of person is this, can't you hope for something, if you really open a BOSS, you should probably cry!

After cleaning up the messy stones, the silver-gray treasure chest was completely exposed in front of everyone, Yi Qingchen stepped forward slowly, took a deep breath, embedded the universal key in the lock hole of the treasure chest, and twisted it gently!

"Click!"

There was a sound of gear running-in in the keyhole of the treasure chest, Yi Qingchen looked at the silver-gray treasure chest in a daze, a kind of person held his breath and was secretly on guard, as if he was really afraid of something wrong, such as opening a boss or something, it would be miserable!

"Ding~!"
