Du Feng was not in a hurry to open the super-large treasure chest, but walked around the hall first, making sure that there were no other mechanisms or other passages here. In other words, the focus of the Water Curtain Cave is the current hall.

While Du Feng was wandering around the hall, the accompanying woman observed the treasure chest for a while. Because the chest is merged, but there's no key or anything like that. It is estimated that like the stone gate, it also needs to be touched to open.

"How's it going, do you see what's coming?"

After Du Feng finished walking around, he asked by the way.

"Well, I see. ”

Don't look at this woman's combat effectiveness, she really has a set of mechanical formations. She did see the method of opening the treasure chest, which was actually something special, similar to the method of opening the stone door. That is, the true element of five attributes is required, divided into fifteen parts, and injected into fifteen different holes at the same time.

Belch...... That's a really bad method.

Du Feng listened for a while, and his head was loud just now, in order to open the stone door. Not only did he use his hands, but he also used the giant arm technique. Now that you need fifteen copies of the True Yuan, wouldn't you have to use five toes?

But if you don't use this method, you won't be able to open the oversized treasure chest, and if you can't open the treasure chest, you won't be able to take the contents inside. Now that they're all here, it seems like a shame not to get them. So he thought about it and had to take off the shoe on his right foot.

I've seen a lot of locks with my hands, and it's the first time I've seen them with my feet.

Du Feng himself was a little embarrassed, but he could only do this for now. Whoever makes his physique special can call the true element of various attributes. If someone else comes in, you won't be able to open the treasure chest even if you see it. The material of this treasure chest is very strong, so don't even think about using brute force to crack it.

And it's connected to the ground, so it's impossible to move it. If you want to get the treasure inside, you can only unlock the mechanism on it.

Du Feng twitched his nose and sniffed his feet first, but fortunately there was no smell. If you take off your shoes and smell of your feet, it will be a shame in front of other girls. Although I rarely use my feet to send out skills, it doesn't mean that my feet can't run the true element.

He first lifted his right leg, and then began to input true elements into the fingers of his hands and right foot. Still in the previous order, gold gives birth to water, water to wood, wood to fire, and fire to earth, and after the five attributes are full, he inserts his right foot and the fingers of both hands into the hole of the target at the same time.

"Crunch ......"

The top lid of the treasure chest began to open slowly, and Du Feng couldn't help but be a little excited. But at this time, he can't let go, or the lid will still close. So continue to output the true element evenly, so that the lid of the treasure chest continues to open, and at the same time pay attention to the woman's movements.

If the woman suddenly rushed over and took the treasure at this time and wanted to run, or wanted to take the opportunity to sneak attack Du Feng, he had to be ready to fight back at any time.

Fortunately, the woman stood there honestly, deliberately standing farther away in order to avoid suspicion. It wasn't until the treasure chest was completely opened that Du Feng withdrew his hands and feet. He stood on tiptoe and looked at the treasure chest dumbfounded.

"Wow, this is a trick!"

It turned out that the inside of the treasure chest was not a treasure at all, but a treasure chest that was one size smaller than the outside treasure chest. In other words, the outer treasure chest is used so hard, just to trap the treasure chest inside.

"Childe, what's wrong?"

The accompanying woman heard Du Feng's swearing, and hurriedly ran over to watch. Because she was small, she had to climb to the treasure chest to look. When I understood it, I couldn't help but giggle.

It is estimated that the predecessor who built the water curtain cave deliberately made a joke with the descendants. Because of the treasure chest inside, the opening method is still the same. It only takes twenty true elements and injects them into the specified holes at the same time.

In other words, Du Feng needs to jump in first and lie on the lid of the treasure chest inside. Then use both hands and feet, and use all twenty fingers to unlock the treasure chest inside.

"Okay, I'll try again. ”

Du Feng was also helpless, he decided to try again. If it's still a treasure chest set treasure chest, then he won't be playing here, even if he has any treasures. When the time comes, if you want twenty-five true yuan, you don't have a third hand or a third leg, so you can't get it at all.

Just as he jumped into the big treasure chest, someone came from outside the stone gate.

The man in black with two hundred and one warriors stopped outside the stone gate. Because the stone people have been wiped out, they don't have to fight hard. However, the unlocking requirements on the stone gate are still difficult.

He took a brief look, then took out two five-color discs. Even if the man in black has two five-color plates, he can't use giant arm skills. If you throw out the five-color disc, or use the Divine Mind remote control, etc., you can't guarantee the timing and quantity of the true element input.

But it didn't bother him, because he knew how to do it. This kind of doppelganger technique is different from other doppelganger techniques, and does not distinguish between the subject and the doppelganger. The three doppelgangers are all subjects, and they can communicate with each other and cooperate with each other.

An obscure spell sounded in the black's mouth, and then he went from one person to two. The onlookers were not surprised, because the man in black had come together as three clones before, but later they merged again.

Now the two clones stood on both sides of the stone gate at the same time, and at the same time raised the five-color disc, injected the true element, and pressed it on it.

"Squeak Crunch ......"

The stone door began to open slowly, and Du Feng had already heard the voice. However, he was lying on the lid of the treasure chest inside at the moment to deliver the true yuan, and he had no time to care about it at all. These people are not the right time to come, it is better not to open it first, lest the treasure be taken by them.

But think about it, since they have a way to open the stone door outside, maybe they also have a way to open the treasure chest. It's better to keep doing it, open the treasure chest and take the things first, and then see how to deal with the people outside.

Du Feng thought it was good, but when the second layer of treasure chests was also opened, he was completely dumbfounded. Because there was still no treasure in it, but a coffin, a coffin made of stone.

Your sister, don't you want to be so pitiful! Du Feng was angry, and scolded the old man who created the Water Curtain Cave eighteen times in his heart.

I made a waterfall of corrosive liquid, I made such a long passage, and I got a stone man to guard the door, and it was so difficult to open the door. The big treasure chest is covered with a small treasure chest, and finally give me a coffin, is there any mistake.

Du Feng has already decided to give up, even if there is a treasure in the coffin, he doesn't want it. And he thinks it's no good if it is opened.
