Welcome to Guanshu Network:

The three-legged toad rolled the staff with its tongue and threw it towards the bronze door with a "bang", fell to the ground, and then moved to look at Cha Wenbin again.

Cha Wenbin looked at its inexplicable behavior, so he had no choice but to walk over, pick up the cane and say, "Man, what are you doing here?" Tantrums? He turned around and planned to go back, but the three-legged toad moved, blocking Cha Wenbin's way.

"You still don't want me to go, right, but you also saw it, there is no way, it is blocked, this door weighs thousands of pounds, how can it be opened." Cha Wenbin looked at the big guy in front of him and patiently explained.

The three-legged toad walked to the bronze door, knocked three times with his tongue on the door, and then retreated to his side again, looked at him, and screamed.

Although Cha Wenbin couldn't understand what the toad was talking about, but along the way, he understood that the guy in front of him was absolutely human, and he was also very smart, and he must have wanted to express something about his abnormal behavior.

While still thinking, the toad's tongue curled, and the staff in Cha Wenbin's hand was taken away by it again, and thrown towards the bronze gate again, and Cha Wenbin had to run over again. Before he could pick up the stick, "Knock knock", three times in a row, the big tongue smashed into the gate again, and this time Cha Wenbin found that the position of the three-legged toad with his tongue twice before and after was actually the same!

The tongue of the three-legged toad has mucus, Cha Wenbin easily found the three points, there are three places on the bronze door that are wet, touch it with his hand, and the cool feeling immediately comes. And these three points happened to become a "pin" glyph, and to Cha Wenbin's surprise, there was a special symbol on each point, which he had seen, and it was the same as the top of the staff in his hand, which were fish, birds and arrows.

Cha Wenbin looked at the staff in his hand and the carving on the bronze door, the three symbols on the door were hidden in the ghost seal, it is not easy to say that it can be seen at a glance, could it be that this door is related to the staff in his hand? With the mentality of giving it a try, Cha Wenbin started with the bird in the lower left corner.

It is a pictographic bird, and judging by the carving technique, although it is not so lifelike, it can also have a tail and wings. If there is anything special about it, it is slightly different from the nearby bronze color, and it is more yellowish, but it is mixed with such a huge door, if it is not specially pointed out by this three-legged toad, it really can't be found.

Cha Wenbin touched it lightly with his hand, and there was nothing very special, this was just a bronze bird the size of a palm, the more he knew at this moment, the more he couldn't be impetuous, so he simply closed his eyes to feel it.

The carving of this bird seems to deliberately use a circle, the whole body happens to be in a relatively regular circle, put down the palm, Cha Wenbin happened to pinch the staff, his heart moved, the size of the circle seems to be consistent with the thickness of the staff in his hand. Thinking of the three-legged toad's movements several times, he threw the staff towards the bronze door, and he had one more word in his heart: key!

"If this rod is the key, it has to have a keyhole." Cha Wenbin muttered to himself to the three-legged toad, but the old man was staring at the bronze door in addition to puffing out his belly there.

Cha Wenbin thought to himself, could it be that this door really has a keyhole, but he can't see it? The head of the rod is also engraved with fish, birds, and arrowheads, so I will try it as if there is no keyhole.

Cha Wenbin simply picked up the staff, and was about to poke at the bird on the door, thinking that it was wrong, and then turned the staff in his hand, so that the bird was facing upwards and pestle against the bronze door, to say that this thing is really so unexpected. This bronze door seems to be indestructible, but Cha Wenbin feels that the staff in his hand is poking at the tofu at this moment, and when he finds that the staff in his hand has half disappeared into the bronze door, a "click" sound.

In this ancient underground world for thousands of years, the bronze door finally made its first sound, announcing that someone had touched the depths of its heart, and the mechanical and dull sound also made Cha Wenbin stunned on the spot. It's obviously a bronze door, why is this rod easily inserted into it?

With a slight effort, he pulled out the staff, leaving a black hole in the bronze door, and there were gold leaf-like things scattered on both sides, and when he tore it off, the thing was torn off.

Cha Wenbin looked at the piece in his hand, which also depicted the head of the bird, and he finally understood that the original bird was just an acquired processing paste to plug the hole, in fact, the material itself was not thick, but a thin layer of bronze was used, and then the original hole was sealed with gold foil pasted on the outside. I poked hard just now, and this barrier was easily broken, and it seemed that I was really right.

Find the first keyhole, then the next two have been pointed out by the three-legged toad, all you have to do is to repeat the action just now, Cha Wenbin is very excited, for this exploration of the unknown world, the curious mentality in everyone's heart will be stimulated, and he is no exception.

Turning back to the three-legged toad and smiling "hehe", giving it a thumbs up, praising its cleverness, and turning to the lower right corner, here is a fish. Cha Wenbin measured it with his fingers, and sure enough, the size was almost the same as the bird just now, and it was also in a circle.

With this spectrum in mind, things will naturally be done quickly. Raise the staff, put the pattern of the fish on it up, aim at the target, pestle in, just like just now, without much effort, there is a "click", and the mechanism is also opened!

Cha Wenbin took a few steps back, looking at the bronze door, now there is only the last one left, this position is at the very top of the door, it seems that there is an arrow carved in the place where the two doors are linked, ancient people need to hunt, so the quality of this weapon often determines the harvest. So the arrow is placed on top, which is also easy to understand, whoever can fill his stomach with weapons can survive, and whoever can unify the tribe with weapons can be the leader. But the height of this arrow is more than two meters, Cha Wenbin tried to jump a few times but couldn't reach it, and there was something under his feet, what should I do?

Just as he was looking around for the stepping stones, he fell on the three-legged toad, smiled "hehe", walked towards the toad, touched its nose with one hand, pointed to the topmost arrow with the other and said, "Man, look, it's too high there, can you wronged you and let me ride on your back?" ”

The three-legged toad was completely unmoved by his conversation, just standing in place. Cha Wenbin touched his head and spread his hands: "Since this is the case, I have no choice but to go out first." After saying that, he pretended to leave, thinking about the next one and turned around, and walked a few steps. Sure enough, the three-legged toad in the back saw that he was really gone, and immediately called out "coo", Cha Wenbin stopped and turned his head to look, the toad reluctantly moved his bulky body towards the bronze door, and lowered his body at the door, as if waiting for Cha Wenbin.

Cha Wenbin walked over with a grin, patted the tip of its nose and said, "Is this a good partner?" When he was about to turn over and ride up, he looked at the pimple on the toad's back, and he didn't dare to go up, but he saw with his own eyes how the corpse silkworm king died on this pimple. Then he snapped the tip of his nose and said, "Lower your head." ”

The three-legged toad squinted at the big eyeballs, probably thinking that you are really welcome, I am also a spirit beast, and I was ridden on my head by you like this, so do you still have face?

But reluctant to reluctant, it still cooperated, it seems that the thing in this cave is really not ordinarily attractive to this three-legged toad.

Some people have ridden horses, some people have ridden camels, but this ancient and modern exchanges, I am afraid that Cha Wenbin, the person who rode a toad, is the first. One rolled over and rode on its head, although a little slippery, but still relatively stable. The three-legged toad slowly raised its head, and its buffalo-sized body advantage was immediately reflected, Cha Wenbin was already able to get the arrow mark, and he thought it would be up to you to do the last time.

With the expectation of the world behind this door, Cha Wenbin raised the staff in his hand and went towards the last point pestle......
