Ning Wuxian crouched down and carefully picked up the leaves covering the footprints with a branch.

Peeling back the layers of footprints, the footprints are clearer, and other traces are also found.

There was bark in the dirt that was trampled into.

He looked up at Yun Fei who was standing next to him and said, "You help me see, is there a place where the bark of the trees has fallen off nearby?" ”

"Childe, what's the shedding method?"

Yunfei asked puzzled.

It's late autumn now, and it's common to lose leaves and bark.

Do you have to go tree by tree to pick up the cracks in the bark and inspect them?

Even during the day, but at night, even if you want to check, sometimes it will inevitably be missed due to the light.

Ning Wuxian picked up a piece of bark that obviously showed signs of knife blade breakage, and said in a deep voice: "Find the place where the knife has been broken." ”

"Great!"

It's not just Yunfei.

Except for Ning Wujian and Qin Shi, who were surrounded on one left and one right as guards, the remaining three dragon guards, including Zhou Jingxian and Jiang Shu, began to squat on the ground along the surrounding trees, carefully inspecting them from bottom to top.

Ning Wuxiao squatted in place and continued to pick up the fallen leaves nearby.

Finally.

His pupils shrank suddenly, and he subconsciously put down the branch in his hand, and when he wanted to pick up the decisive physical evidence with his hand, he thought of its composition, so he could only pick up the branch again, and moved closer with broken steps.

Then, little by little, the puddle of wet mud, which was full of mottled rust embroidery, was dug out of the soil.

When he saw the chaotic sawdust on it, a picture flashed through Ning Wuxian's mind.

A short Beidi man walked in the dense forest with an iron rod taller than others, for fear of being discovered by the people in front of and behind the Huangzhuang, his speed was fast, but due to the rain and the road was slippery, so he slipped in this muddy place.

Therefore.

The iron rod hit the trunk of the tree and rubbed rust on the bark.

Fearing that the rust would be discovered by the people in the Imperial Village after the rain stopped, he scraped off the bark with a knife, stepped into the dirt, and covered it with leaves that had hidden the traces of shoe prints.

If it weren't for him, a person who firmly believed from the beginning that the lightning strike of Huashi was not an accident, then all of this would not have been discovered.

When the autumn leaves turn into mud, everything becomes seamless.

But!

Now he has found this evidence, confirming his suspicions.

It is true that the Chinese division was buried in this area in advance, and after determining the approximate range of the mine, he was connected to the iron frame in the carriage and fixed the small area.

Only then did he receive several lightning strikes in a row, and finally died!

This is not an accident.

It's murder!

A murder against the Chinese Division!

"Childe, I found it!"

At this time, Yun Fei, who had already climbed the tree, stood on the branch and pointed to a place about eight feet away from the ground.

"There's a piece of bark that's been scraped off here, it's the size of a palm, you don't have to come up, you can see it just by holding a torch underneath."

Yunfei is relatively short.

Ning Wuxian heard his words, tiptoed, raised the torch again, and looked up to see the bare tree trunk.

He stretched out his palm and compared it to the trunk of the tree, confirming the size of the contact area of the object, deducing their maximum diameter, and then drawing a conclusion based on the depth of the footprints.

The iron tools used by these men to draw lightning in the woods were about the thickness of an arm's arm.

If you have a strength, you'll be at least eight feet tall.

But at this height, it is impossible to bury under a tree to guide mines, as for connecting them together...... Not to mention Beidi, Daxing does not have the kind of casting process of threaded buckles.

In the case of lightning channeling, if two iron tools are tied up, it is very likely that the binding object will be destroyed, which will cause the direction of the lightning to deviate and hurt oneself.

So.

They must have chosen the terrain on a high place.

After Ning Wuxian handed the torch to the third brother beside him, he spat at the palm of his hand, found a big willow tree with raised bark nearby, climbed up more than half a person with his hands on the trunk, poked his head out, and after being able to see the terrain here, his eyes fell on a bare mountain bag not far away.

The mountain was only two hundred meters away from where they were, but because of a river in the way, it would take a mile or two to detour, and from afar, you could see that the rocks were being chopped up in a mess, and there seemed to be a smell of lime in the air.

There it is!

All you need to do is insert an iron rod there to lure the thunder over!

Knowing their methods and tools, and confirming that they did not possess the subtle things of the real lightning control technique, Ning Wuxian breathed a sigh of relief in his heart, and at the same time, an unprecedented anger surged into his heart.

"Why?"

Ning Wuxian asked in a muttered voice.

"Why did they kill Huashi?"

Huashi devoted himself to medicine in this imperial village, and he had no intention of participating in any struggle.

The Beidi people have taken such a big risk, and they have to bear the risk of possible failure, just to lead the thunder to an old man who has nothing to do with the competition, are they idle and have nothing to do?

Crash!

At this time, Zhou Jingxian jumped up directly from the dry land under the tree, looked around nervously, and asked expectantly, "Mr. Ning, have you found any evidence?" ”

"Hmmm......"

Ning Wuxian just nodded, and didn't explain all this.

Instead, Zhou Jingxian proposed: "Mr. Ning, the craftsmen who raised the frame with iron tools for the carriage that Steward Zhang mentioned just now should also be registered with the Ministry of Industry, why don't I arrest them and interrogate them first?" ”

"No, if it's because of the iron frame, shouldn't those caravans be more thundered, it's none of their business, but we can ask Steward Zhang when the carriage was raised."

In the dark.

Ning Wuxiao had a hunch.

Huashi's death may have nothing to do with him.

Ning Wuxian let go of his hand and fell to the ground, and glanced at the traces in the dirt again, a sharp cold light flashed in his eyes.

Regardless of the motive of the Beidi people for killing Huashi, since it has been determined that the murderer is a Beidi person, he will avenge Huashi.

He wants to return a tooth for a tooth, so that the people who do it can have a good experience of how the lightning controller was struck by lightning!

"These leaves are just hanging like this, and when Your Majesty comes, please ask Your Majesty to come and see where this Beidi people have infiltrated."

The truth of the matter, it is inconvenient to tell Zhou Jingxian them.

But the old emperor had to know.

After all, iron tools need the old emperor's nod and consent before they can be used.

Returned to the place where the accident occurred.

Ning Wuxian took matters into his own hands, and together with Zhou Jingxian, carried Hua Shi's body back to Huangzhuang.

Taking advantage of the fact that the old emperor had not yet arrived, he first asked Steward Zhang about the recent changes around Huashi and the contact between Huashi and the outside world.

Steward Zhang thought about it carefully, shook his head and said: "Since Master Hua came to Huangzhuang, he has not been in contact with the outside world except for drying and planting medicines, and even His Majesty said that he wanted to invite him into the palace, but he politely refused...... That's right! ”
