If you think of brute force to open this, it will take some effort.

"Teacher, it's a pity that we didn't bring explosives this time." Mike said with some regret.

"Nothing!"

Who would have thought that Miles directly scolded.

"What's wrong with the teacher?" Mike was puzzled.

"I don't know how long it has been built in this kind of place. Do you still want to use explosives? If it collapses, then all our efforts will be wasted."

"The small amount of explosives cannot blow up this door!"

Mike scratched his head innocently and asked, "Teacher, what should I do?"

"Generally speaking, this kind of thing will record the way to open it to avoid losing the way to open it."

Zhang Xian walked into the door slowly.

Observe for a while.

"Will it be recorded there? Why not in the book?" asked Mike.

"There is always a possibility of being lost or lost. If you want to prevent the method of opening, there is only one way, which is to record the method of opening around."

After a while.

Zhang Xian began to carry a small shovel and began to insert it around the ground from time to time, or pass it through.

The people around him didn't understand Zhang Xian's approach. What was the reason?

However, just after Zhang Xian's shovel suddenly made a thud, everyone understood Zhang Xian's purpose.

"It should be here."

Zhang Xian immediately started digging with a shovel, and after a while, a small hole was dug out.

As the pit became bigger and bigger, things under the soil gradually exposed.

It seemed like a copper plate.

But after a lot of erosion, I can't see the things on it clearly.

But you can still vaguely see that there are some patterns on it.

"What is this?" Myers also came over with curiosity.

He is really not as good as Zhang Xian knows about this aspect of knowledge, and he has specialized in his profession.

"There is a high probability that the method of opening the door is recorded."

Zhang Xian wiped away the dust from the copper plate, and used a broom and water to remove some rust on it.

Then I could see some patterns slightly.

The content on the pattern is also relatively simple and easy to understand.

After thinking for a while, Zhang Xian said, "The three patterns on them probably mean the three keys to open the door, which are in different places in this canyon."

"Only three keys can the gate be opened."

"So troublesome? Why do these people always like to make simple things so long-winded?" Mike complained with a pout.

Miles knocked Mike's head and then said in a deep voice: "Stop talking nonsense. Now I still have to find these three keys to lock them. I don't know if so many years have passed, and the key is still there."

"Generally speaking, there are special preservation methods. Even if the part has been corroded, it should be used." Zhang Xian said.

"Since that's the case, let's look for it separately. These three patterns should be the location of the key. As long as you find the same pattern, you can find the corresponding key."

Zhang Xian pointed to a part of the pattern on the copper plate and explained.

"Leave the matter of finding the key to us." Kobe Ichiro took the initiative to take the initiative.

"Our Su family can also do someone."

Miles said to Rand and the others: "You guys go too, it should be safer here."

Lin Fan spread his hands: "Since everyone is going, I have no reason to stay here."

Several groups of people looked at each other.

Everyone knows it.

This thing will be an important bargaining chip.

Whoever can find the key will have greater say in a while.

Seeing this, no one hesitated.

After remembering the patterns on the copper plates, they were all dispersed.

Soon there were only a few students, Su Wanrong and others in the cave.

Lin Fan walked in the canyon and passed through the trees.

"Where should this huge forest be there?"

Lin Fan recalled the patterns on the copper plate I saw before, one of them.

There seems to be a little monkey holding one of the keys in his hand.

"If there are really living creatures, it is very possible to find monkeys, but no matter how many monkeys have been around for thousands of years, they will never be able to live until now."

"What does this monkey mean?"

Lin Fan walked around and looked around, trying to find some clues from the surrounding environment.

The surrounding wind and movements all entered Lin Fan's consciousness.

Lin Fan used his internal strength to amplify his five senses, and his exploration of this environment also reached the extreme.

Then I kept searching on the road.

Sudden.

The hole on a huge mountain wall attracted Lin Fan's attention.

"That place seems a bit special."

Lin Fan looked at it and found that there were some places to borrow.

So I quickly climbed on the mountain wall and soon arrived at the entrance of the cave.

There was only one cave entrance of about one meter here, and Lin Fan could only bend down and climb in.

And there seems to be another space in this cave entrance.

"It seems that there is something inside!"

Lin Fan took action to excavate.

After digging for a while, I suddenly felt my fingers pause.

"Can't dig any further?"

Lin Fan cleaned it up and found that there was also a copper plate inside.

The surface of the copper plate is the pattern of a monkey.

In the middle of the monkey pattern, a swaying stick slid down.

“Is this part of the key?”

Lin Jiang was not sure, and to be on the safe side, he dug out the entire copper plate.

Finally, a square piece of copper plate the size of a pot lid was dug out.

Lin Fan pressed the stick and came out with a gap in the center.

Then he hid the entire copper plate.

Back to the ground.

Lin Fan checked and found that the copper plate had corroded severely, but the stick in the middle was probably much new.

"Because it is embedded in it, is it better to protect it?"

After thinking for a moment, Lin Fan decided to return.

Although it is still early, I don’t know if anyone else is looking for other parts of the key.

But Lin Fan didn't want to find all the keys.

If Lin Fan only gets a key part, and the other part is obtained by another person.

Then this thing is a good bargaining chip.

But if Lin Fan alone accounts for the majority, then this thing may lose its role in negotiations.

Others must check and balance to play their greatest role.

"It would be best if the Su family and the scientific expedition team each found a part so that they could check and balance each other, so that I could get more."

Lin Fan put away the copper plate.

Immediately returned to the previous cave.
