Three hundred years before the founding of the Bi Kingdom, almost all the iron tools in the army were supplied by the Bai family in Yixian County, and most of those iron tools were also cast from Yanyu Mountain.

Of course, Yanyu Mountain itself is not high, and there are not too many trees until now, except for the use of spring water flowing down from Yanyu Mountain, it is almost no longer used in Yanyu Mountain to burn bronze and iron tools.

During the day that Emperor Xi was in a coma, Ning Yi and they were not idle, and they also found out that up to now, there are still two sword-casting workshops in Yanyu Mountain that have been operating, but the scale is not large.

On the way to Yanyu Mountain, Emperor Xi heard them talk to him like this, and his heart was inevitably a little upset and uncomfortable.

If Yanyu Mountain has been developed like this, then it stands to reason that the possibility of Mr. Kunwu being hidden on Yanyu Mountain is already very small, after all, it is unlikely that an overexploited place will have an excellent hiding place.

Thinking of this, Emperor Xi's heart inevitably felt a little frightened. If it weren't for Ye Yueming's determination that Bishan Mountain was the value of Yanyu Mountain, she might have to go home at this time.

Walking out of the west gate of Yixian County for less than two miles, you can see the figure of Yanyu Mountain not far away.

Similar to the rumors in Yixian, Yanyu Mountain is indeed not tall, it looks like an ordinary small hill, and the vegetation of this hill is not dense enough, presumably in the past few years, there are a lot of trees cut down on the mountain, which is a bit decadent.

Emperor Xi looked at Yanyu Mountain from a distance, and the uneasiness in his heart became more and more intense: "Do we really want to go up?" ”

Not only does she not feel that Mr. Kungo is here, but she even faintly feels that there is a lot of cats here.

"It's all here, we have to go up and have a look, besides, if we confirm that Mr. is not there, it won't take much time for us to go down the mountain directly." Ye Yueming crossed her hands on her hips, and after looking at Yanyu Mountain from afar for a while, she still felt that she should go up and take a look.

Emperor Xi was not a particularly strong-willed person, and she was already in the mountain when she leaned back, so after thinking about it, she still followed everyone up the mountain.

Although the altitude of Yanyu Mountain is not high, it is really a headache to climb. If it weren't for the gentle terrain, it is estimated that the way to climb the mountain would have persuaded a large number of people to retreat.

As soon as Emperor Xi entered Yanyu Mountain, the first feeling was strange.

That's not because the pattern of the entire Yanyu Mountain is strange, but because Yanyu Mountain has been casting iron for so many years, so the air in the mountain is not like an ordinary mountain, the air is sober, but there is an indescribable smell of rust and burnt smell left by burning charcoal, such a taste is not easy to ask, especially for the emperor, it can make her feel uncomfortable.

She couldn't help but hold her breath, and she could breathe a little less: "The smell here is too bad." ”

"It's not just a bad smell, look at the leaves in Yanyu Mountain." Ye Yueming said, nodded at Changli, Changli flew up, and then cut off a small branch with the sword on his body and handed it to Ye Yueming.

Ye Yueming put the branch in front of the emperor and said, "Come and see." ”

When Emperor Xi took a look, he found that even the leaves had a strange trace that could not be explained: "...... is this?" ”

"Rust." Ye Yueming is more familiar with these: "There are actually foundry workshops in the army, so near the Sword Casting Division in the palace, there is also such rust everywhere. ”

After Ye Yueming familiarly explained the origin of these rusts to the emperor's seal, he threw the branch on the ground: "It seems that the sword has been cast here for a long time. ”

Emperor Xi nodded: "Yixian's iron casting skills are superb, and it is not a strange thing in the Bi Kingdom. It's just that I'm puzzled, if the air in Yanyu Mountain is like this, can Mr. Kunwu stay still? ”

"According to the words of the Hades King, I am afraid that Mr. Kungo is already half dead, where would a living dead person care what the air is like." Ye Yueming hooked Gou Chunjiao, and talked about Kunwu without any due respect, but Emperor Xi knew that this was due to Ye Yueming's character, and he was still very concerned about Mr. Kunwu's safety.

Hearing Crane hear Ye Yueming say this, he couldn't help but glare at Ye Yueming, but he didn't say anything, obviously because even Tinghe knew what kind of character Ye Yueming was.

"Let's find him first and then lean, he is alone in the mountain, if there are any clues, lest we look for him again." After thinking about it for a while, Emperor Xi decided to find it first and lean back.

Tinghe nodded, and said after the operation, "Follow me." ”

"You know where the leaning back is?" Emperor Xi was a little surprised.

Listening to the crane snort, he said, 'I told him to leave a mark in the mountain, and we just have to follow the mark to find him.' “

"I don't need to bother you." The voice leaning back came at the right time: "You come with me." ”

Leaning back and speaking, he appeared in front of Emperor Xi steadily, and did not forget to smile at Emperor Xi: "Ah Luan." ”

"Have you found Mr. Kungo's whereabouts?" Di Xi was so confident when he heard what he said, he was inevitably a little excited.

Leaned back and shook his head: "I didn't find it, but I found a little clue, you come with me." ”

Leaning back didn't just say the words to death, but asked them all to go with him. Emperor Xi did not hesitate, and leaned back and walked deep and shallow into the mountain.

This mountain has been dug a little too badly, almost everywhere potholes, but fortunately, the water veins have not been destroyed, and the act of cutting trees in this mountain has gradually decreased over the years, so although the whole mountain still looks a little miserable now, it is quite passable to walk now.

After walking several laps into the mountain, they finally slowed down.

"Right here?" Emperor Xi was a little surprised.

There is basically no difference between these four areas and other mountain passes, and I can't see anything that is different, and naturally I can't see what belongs to Kungo here.

Leaning back and smiling, he didn't answer the emperor, but stretched out his foot and stomped twice.

Emperor Xi didn't know what he was going to do, so he quietly watched the backward performance, but it was also strange to say that after leaning back and stomping these two feet, a deep pit appeared on the ground, and it was very close to the location of Emperor Xi.

The cold hairs on Emperor Xi's body immediately stood up.

When she was in Ningshan, she fell into a deep pit for this reason, and found a broken national seal inside, and that experience made the emperor seal have an instinctive resistance to such a sudden collapse of the pit.

"Don't tell me, Mr. Kungo is here." Emperor Xi's face was full of three big words of reluctance.

Leaning back and shaking his head, he waved his hand and said, "Not in here." ”

Emperor Xi just breathed a sigh of relief, leaned back and continued: "However, the clue is here. ”
