Li Kunlun suddenly remembered that when he first entered the valley, Lehua came from the back mountain, and he also went to the back mountain during the crime, and later several people died, except for Xue Yuer, who was buried by Xiao Rui in the valley mouth flower field, the other three were taken to the back mountain by Yuantai.

Then there is a general idea, if Yuantai really knows the sword, what happened is probably that Lehua and Yuantai killed the three Qian shopkeepers for unknown reasons, and then Lehua chose to die to protect Yuantai.

Then the reason behind this serial murder case is only known to Yuantai, and their secret should be hidden in the back mountain.

The back mountain is the forbidden land of the Medicine King Valley, except for the Lord of the Valley and his three disciples, the rest of the people are not allowed to go casually, there is only one way: break at night.

After making up his mind, Li Kunlun lay on the bed after the lights went out that night and did not sleep, until the husband shouted the third watch, and then went to the back mountain alone by the bright moonlight.

Li Kunlun walked half a stick of incense from the path on the right side of the village before he saw a retracted suspension bridge and a hanging cliff below the suspension bridge.

To the right side of the suspension bridge is a bamboo house suspended from a stone wall, and it is likely that there are disciples on duty inside.

"If you put the drawbridge down, I'm afraid it will alarm them," Li Kunlun thought to himself.

After thinking about it for a long time on the edge of the cliff, Li Kunlun made up his mind to find out the truth, so he took advantage of the moonlight to look at the distance to the other side.

"It was at least five zhang wide from the other side, and I couldn't jump more than three zhang away, and there was no way I could jump over it. Li Kunlun was secretly distressed.

I had to look around to see if there was anything useful, and after looking for a long time, I finally saw a large piece of broken wood in the grass, Li Kunlun tried to knock it, and it was quite strong.

I saw Li Kunlun come to the cliff, throw the broken wood upwards with all his might, and when the broken wood was about to fall, he ran two steps and jumped forward, freeing up more than three zhang away, and the broken wood just fell.

Li Kunlun stepped hard with his right foot, and the body that was about to fall jumped more than two feet away, and then landed firmly on the opposite side. And the broken wood that fell off the cliff did not make a sound for a long time.

"This is going to fall, it will definitely be shattered" Li Kunlun turned around and looked at it, a little afraid.

Li Kunlun looked forward for a week, a little depressed.

It is said to be a back mountain, but it is actually a single mountain that rises straight up from the bottom of the cliff.

Except for the three desolate graves, there are some towering rocks, and beyond that there are thousands of deep cliffs.

"Don't say it's a clue, there's not even a ghost," Li Kunlun was lost for a while, and took such a big risk to come over, but there were only these three graves.

"Forget it, it's all here" Li Kunlun was unwilling and walked towards the three deserted graves.

Three deserted tombs are lined up, and in front of the graves stands a wooden sign with the name of the owner written on it.

"Strange, this is too sloppy, no, it's more sloppy than sloppy," Li Kunlun was very puzzled after looking at the three wooden cards.

The three wooden plaques are supposed to be taken on the spot, and the bamboo pieces have been simply fired, and the words on the bamboo pieces are scribbled, as if they were carved with a sword at random.

"Something is wrong, if the money shopkeeper and Jiang Yanzi are from the Yue country, Yuan Tai is unwilling to work their wooden cards, it is reasonable."

"The wooden sign of Colahua is so simple and sloppy, it is not reasonable in terms of the feelings of their senior brothers," Li Kunlun thought to himself.

"Isn't it Lehua here, or ......?"

After some inner struggle, Li Kunlun still chose to trust his intuition.

I cut a few wide bamboos with a peach creek sword, wound them with bamboo branches, made a simple bamboo shovel, and began to dig graves.

Shovel after shovel, busy for a long time and finally dug up the bamboo coffin, Li Kunlun had heard the white shopkeeper say that the bamboo coffin in the Medicine King Valley was soaked in a special medicinal juice for many years, but it did not rot for many years, and today I saw it with my own eyes, and it was really a little peculiar.

When the coffin came out, Li Kunlun no longer hesitated, and used the Taoxi sword to pry open the wedges along the edge of the bamboo coffin one by one.

His conjecture was about to be revealed, and Li Kunlun couldn't help but feel a little apprehensive in his heart.

With the lifting of both hands violently, the contents of the bamboo coffin were revealed.

"It seems that I guessed correctly," Li Kunlun muttered to himself as he looked at the only bamboo heart sword in the bamboo coffin that had been broken in two.

But there is nothing but stones in this back mountain, Lehua must be dead, what he saw with his own eyes cannot be fake, is it possible that Yuantai threw his body off the cliff and set up a weapon mound here, how is this possible.

Li Kunlun was laughed at by his own thoughts.

"It must be what Lehua's body was used for," Li Kunlun analyzed, "It's better to ...... than guess."

After a long time, Jiang Yanzi's bamboo coffin was also opened.

"It's an empty tomb again, what does Yuantai want their corpses to do" Li Kunlun was puzzled.

Looking at the last lonely tomb of the money shopkeeper, Li Kunlun was a little entangled, it seemed that there was no need to excavate, even if it was opened, it was very likely that it would be an empty tomb, so it was better to hurry up and backfill the two tombs.

Li Kunlun was about to backfill the two empty graves when he suddenly discovered something.

"It stands to reason that the shopkeeper died the earliest, and his grave should be the oldest, but the saplings on the soil of this tomb are even shorter than the other two."

"Could it be that another boring guy has come to dig the grave of the money shopkeeper?" Li Kunlun shook his head, determined to dig it up.

Shovel after shovel......

After a long time, the last grave was finally dug up.

If it weren't for the fact that he had practiced swordsmanship for three years and his physical strength was not bad, he would have to lie here tonight after digging these three graves. Li Kunlun secretly rejoiced.

The bamboo coffin of the money shopkeeper emitted a strange smell of medicine, which was completely different from the other two bamboo coffins.

"It seems that there is really something famous here," Li Kunlun thought to himself, and resolutely lifted the lid of the coffin.

"Wow" Li Kunlun was so frightened that he retreated a few times after seeing the contents of the coffin.

"That black thing is a human and a ghost," Li Kunlun was a little timid.

After being stunned for half a cup of tea, I finally mustered up the courage to step forward.

The one in the coffin said that it was a corpse, but it did not emit any foul smell, but had a faint smell of medicine.

The whole body was black, and the face was no longer visible, but the body was very full and didn't look like it was rotten.

The skin of the whole body is a little cracked, and the tiny cracks are very penetrating.

"Is this the money shopkeeper, how could it be like this" Li Kunlun was very puzzled.

In the end, I couldn't help but touch the skin behind me.

It was very hard, as if it had touched the iron armor formed by countless pieces of iron. Hitting it hard also makes a thumping sound.

"What the hell is going on" Li Kunlun squeezed hard, but the corpse's arm did not change in the slightest.

"It's such hard skin, I don't know if it will work with this"

"The junior of the money shopkeeper has no intention of disturbing, he just wants to solve this mysterious case in the valley and avenge you, but don't blame me" Li Kunlun clasped his hands together and muttered for a long time, stabbing the corpse's arm with the Taoxi sword.

However, it still had no effect.

"This, the Taoxi Sword is not a divine weapon but also a sharp weapon, in the past, ordinary iron weapons were like mud in front of him, and this corpse was so hard" Li Kunlun was shocked, and then swung his sword hard and slashed at the corpse, as expected, there was still no damage......
