Go to ancient times to catch fast

Hearing this, Xie Xun already understood, and he said to his subordinates: "Go to the nearest mining area and pick up all the ore workers to check the pig iron situation in the soil in this area."

Wei Jinghan said with a smile: "As expected of the deputy general of the six gates, Mr. Xie is amazing."

Xie Xun said: "Master Wei is over the award. I don't know if Master Wei has any opinions?"

Wei Jinghan said with a smile: "Since Mr. Xie has already sent someone to invite Baigong, we don't have to be idle. First, check whether there is another cave in this underground palace."

"I have the same opinion as the two adults." Chu Xiaoyun said with a smile.

"Since that's the case, the brothers should cheer up and search carefully in this underground palace inch by inch!" Xie Xun said.

After the order was issued, everyone started a new round of searching in the underground palace.During the period, Chu Xiaoyun reminded the yamen servants to catch up quickly: "We must search carefully, and we must not let go of any clues."

While reminding the officials to search carefully, he did not give up and continued to study with the map. After looking at it for a while, he did not find any new discoveries from the clear map. Pointing at the undeciphered pattern, "Could this be the cavern of this underground palace?"

Jie Xun and Wei Jinghan stopped to look at each other, and said in unison: "It makes sense."

Jie Xun said again: "It's just that this map seems to have no clue, it's not as clear as other maps."

Wei Jinghan took the map and looked at it carefully, and suddenly remembered something, he looked at the drawing for a while under the light of the torch, folded the drawing in half, and then looked at the torch.

While they were studying the map, the people from Six Doors had already picked up Baigong to check the soil quality of this place, and there was indeed pig iron content, which was a continuation of the Yunling Pig Iron Mine.But the content is too small, not enough to affect the direction of the compass, resulting in a labyrinth.

After listening to Baigong's words, Chu Xiaoyun became more motivated to find the "hidden hole" in the underground palace.At this time, Wei Jinghan also discovered the mystery from the folded map.It turned out that after matching the messy figure drawn from the finger with the map of the dungeon outside, a new map would be displayed.

The crowd cheered.

"Master Wei is really well-versed in poetry and books, and he is so smart that he can even see through the secrets hidden in it." Fangchuan county magistrate flattered him.

In the end, according to the map instructions discovered by Wickingham, they found the entrance to the cave marked on the map in a place that looked slightly different from the surrounding stone walls.It's just that the appearance on the ground has changed a lot from the map.As for this place, they had passed by it three times but did not find it.

"It seems that the entrance to the inner city has been changed." Xie Xun said.

"Unexpectedly, that counterfeit would not give up before leaving." Chu Xiaoyun sighed.

The policemen removed that layer of camouflage, and a magnificent stone gate was displayed in front of everyone.

"Unexpectedly, there is really a hole in the sky here." Although it was expected, but when he was really standing at the gate of the inner city of the underground palace, Chu Xiaoyun couldn't help feeling, "I didn't expect that fake Gu Qingyun to escape in panic. It really took us a lot of effort to make such a disguise. If he hadn't played tricks on it, we wouldn't have wasted the extra time."

"However, because he left in a hurry, the color and rough workmanship of this camouflage let us see the clues. There must be something in it, maybe a lot, otherwise he wouldn't make such a camouflage." Xie Xun said .

"Good." Everyone agreed.

"It's just how to open the gate? Since the fake Gu Qingyun has fled, he will never leave the key to open the gate in the underground palace and leave it to us." Fangchuan county magistrate said.

Everyone's joyful expressions were tainted with a layer of loneliness.

Xie Xun still decided to go up to check it out, he also knew a thing or two about Qimen Dunjia.After looking at it for a while, he said happily: "Judging from the layout and lock on this gate, there is no trace of it being opened recently."

"Master Xie, do you mean that Gu Qingyun does not have the key to the inner palace?" Chu Xiaoyun hurriedly asked.

"It's very possible." Jie Xun urged, "Captain Chu, think about it quickly. When you went through Zhang Cheng's case, did you find any relics of him similar to this key to the underground palace?"

Chu Xiaoyun and Wei Jinghan thought about it for a long time, but there was no such thing in their memory.

"Is it possible to go to the Zhang family to search and arrest?" Wei Jinghan said, "In this way, if the Zhang family refuses to hand it over, they may also get the news and deliberately conceal it, looking for opportunities to open the underground palace. A bunch of keys, if the Zhang family finds out , it's too easy to hide."

Chu Xiaoyun was silent for a while, but said: "Zhang Cheng and his wife are not only in harmony, but according to the situation we have now, they may be in the same situation. If Zhang Cheng did it, his wife would never know where the underground palace is. , let alone know where the key is.”

"By the way, what is hiding the map?" Jie Xun, who was silent on the side, suddenly asked.

"Hairpin, finger pull?" Chu Xiaoyun also remembered, and hurriedly took out those two things from his arms, compared the finger pull on the key for a long time, but it didn't work; then took out the hairpin, pointed The tail of the hairpin doesn't match the keyhole either.

At this time, Fang Linghui, who was holding her breath and watching all this, suddenly cried out excitedly: "The tail of the hairpin can be removed. The craftsmen of the Equipment Bureau have already discovered it, but later they found a map on the head of the hairpin, and thought it was a secret. At the head of the hairpin, I did not pay attention to the desirable function of the tail. I also forgot to tell you."

"Take it off and have a look." Wei Jinghan said.

According to what Fang Linghui showed, Chu Xiaoyun took off the decoration at the end of the development, and a key that was the same as the lock cylinder of the underground palace gate was displayed in front of everyone.

Unexpectedly, there are so many secrets hidden in this hairpin. Zhang Cheng's trust in his servant is really rare.Fortunately, he had such loyal servants that they could discover this hidden underground palace.

Chu Xiaoyun inserted the hairpin into the door lock, turned it gently, and the gate of the inner city of the underground palace opened in response.
