"New thorn grass, perennial herbaceous plant, no vanilla smell, generally has seven to eight pinnate leaves, the leaf margin is serrate, often mixed with ordinary pasture grass, can cause diarrhea after eating; The sap of the two plants has a slight corrosive effect when mixed, and long-term human consumption can lead to chronic damage to the body's organs and eventually death, with death symptoms similar to natural organ failure......"

The first part is the information of the two plants found in the dossier, because they are both common plants in daily life, and there are not only written records but also physical specimens in the library. The effect of mixing the two plant juices was obtained by Gehr after establishing an analytical model.

Baron Andrei's death was not an accident or a natural death of aging, but someone deliberately destroyed Baron André's health through covert long-term poisoning, and finally made the Baron weak and die.

"Sophia, do you know who was responsible for Grandpa's diet in the last three months of his life? From the time the ingredients entered the tower to Grandpa's mouth, everyone who handled the food. Gehr looked up at the sun directly above him, and it was a little glaring, causing his eyes to squint.

According to the information provided by Sophia, Baron Andrei started to fall ill two months before his death, and considering that the damage to people from this poison will not appear immediately, it is estimated that there will be an incubation period of one month, so Geer expanded the suspect to people who have been exposed to Baron Andrei's food within three months. However, the people in charge of such things in the castle are very fixed and there is almost no movement, so it is not difficult to find.

"Most of what I know, a few I'm not sure about. Sophia was very keenly aware of Gehr's strangeness, and thought carefully for a moment before replying.

"That's enough, Sophia, you go back first, and take all the people you can be sure of to the tower, and the rest you can't be sure of, whether there is evidence or not, bring it first, and it is better to be wrong than to let it go. Clover, Leeux, you accompany Sophia, if anyone resists, you just break his leg and drag him to the tower, if you don't want to, you can kill him directly. ”

"This ......" The two knights named were taken aback, after all, they were knights and not thugs, and they were still a little resistant to doing this kind of thing against civilians.

Sophia didn't hesitate and agreed directly.

"Is that enough for the murder of Baron Colborne?" said Gehr lightly.

"If you have solid evidence, you can leave it to the Imperial Law......" Clover and Leeu looked at each other, and Clover replied respectfully.

"Is the evidence important? or do you think it's better to dispose of it all?" said Gehr as if he were a god on high above, looking at the people below with that kind of indifference.

Clover froze slightly, not daring to say anything more.

For the first time, the four knights realized the true face hidden beneath the peaceful exterior of Gerna, a faint chilling coldness that was very close to the one they respected and feared Prince Faelino.

When Gehr and Kevin, who were guarding the outermost part, joined up, Sophia and the two knights left the group and headed for Winterdusk Castle.

Kevin was a little skeptical, but since Gehr didn't say anything, he didn't say anything in the end.

There is an abandoned copper mine nearby, which is one of the suspicious points circled by Gehr on the data yesterday, and since he is nearby, he has just gone to investigate.

"This mine was developed by the lord sixty years ago, mainly producing copper ore and some associated gold, but the amount of gold is very small, the proportion of copper ore content is too low, it can only be regarded as a poor mine, plus there are many copper-rich mines in other parts of the country, so this copper mine has only barely maintained since it was mined, until twelve years ago, when the veins of this mine were exhausted, the baron ordered the complete closure of the copper mine, and it has been abandoned until now. ”

Kevin takes Gehr to the copper mine and explains it accordingly. What Kevin said was also recorded in the dossier, and after comparing them with each other, Gehr nodded.

"Young Master, this is it. ”

Gehr took a few steps forward and came to the direction that Kevin was pointing at.

It was a mine opened in strict accordance with national mining standards, the entrance was high enough for an adult man to jump, and the walls of the cave were firmly supported by thick wooden piles and nails on top of each other, which can be imagined the effort that went into its construction. Unfortunately, now it is just an abandoned mine hole, weeds cover the hole, the wooden stakes and sleepers inside have rotted, and the iron part of the track on the ground has long been dug up.

In Gehr's mind, what Earl Carter wanted was to control the Colbenson Domain, so it was likely that some kind of resource in the realm attracted him. Things like Colebenson's unique knight training methods don't need to be so troublesome at all, and they can be easily obtained, and only the resources contained in the land cannot be moved, and among the various resources, minerals have the greatest probability.

Since Earl Carter can make a resolute move, it means that he must have a positive answer, and he must have investigated on the spot, so as long as he goes to various mineral resource points to see if there are traces, he can figure out what Earl Carter wants.

This copper mine is no longer a problem, and it can be eliminated - one of the lists in Gehr's mind has been crossed out.

Just as he was about to leave, Gehr suddenly felt that someone nearby was peeping at him, a stupid guy who didn't know how to hide, Gehr instantly roughly determined the location, but he didn't act immediately, but quietly adjusted the range of sight to further determine the exact location of the peeping person to determine the next countermeasure.

At this time, Isolde also felt the peeping, and immediately roared: "Who is it?!"

Gehr frowned slightly, a little dissatisfied with his somewhat reckless behavior, but this was not the time to speak, and immediately looked at the approximate location of the peeper, as for when the first soldier rushed over to catch the peeper, Gehr didn't have this idea, and the remaining three knights around him were not decorations, so there was no need to take the risk himself.

Isolde screamed and threw himself in the direction he thought he wanted, and let out a corresponding exclamation from behind a bush, but in the bush where Isolde entered the sound, the peep still did not make any escape, which was very strange.

Isolde's two companions felt that something was wrong, and were about to go up to answer them, when they saw Isolde come out with a strange face, carrying a child dressed in tattered linen clothes in his right hand.

Apparently, they misunderstood and turned a naughty child into a voyeur.

Seeing so many people staring at him strangely, the child burst into tears as soon as he was nervous, snot and tears, which embarrassed Isolde, who was carrying him, but he didn't get Gehr's order and let him go directly, so he could only look at Gehr for help.

"Young master, this is the child of the nearby miners, not a dangerous person, let him go. Kevin said.

"Let him go, Isolde. Gehr's words freed Isolde from this "predicament."

The tall knight immediately put the child back on the ground like a hot potato, and the child was not ambiguous, and as soon as he was free, he immediately pulled out his legs and ran, and in a moment disappeared into the woods.

"Kevin, how are there miners here? Isn't the copper mine abandoned? I remember the iron mine is in the other direction, so I shouldn't have come here. Gell looked at Kevin beside him, waiting for his explanation.

"That's right, young master. After the closure of the copper mine, the lord let the miners working in the copper mine go to the iron mine to continue working, but the iron ore in our territory is not abundant, the scale of the mine is very small, and these miners appear to be overstaffed as soon as they pass, so the treatment is reduced, and they are all full and hungry. Some miners can't stand this kind of life and run back to mine copper. ”

"Isn't the copper mine exhausted?"

"Yes, young master, the main veins of the copper mine have been mined, but there are still some small branches, and these miners are secretly digging holes to mine the copper ore of the branch veins. Because the branches have no value for large-scale mining at all, these miners are superfluous to the territory, but they can't help but give them a way out, so the behavior of these miners Lord Baron is to turn a blind eye and turn a blind eye, when he doesn't see it. ”

Gehr didn't expect this kind of secret, but he could also understand Baron Andrei's concerns. If these miners can't survive, then in order to survive, they are likely to become a gang of bandits, although they can be destroyed at their fingertips for the baron, but it is always a troublesome matter, and it is not good for the security of the territory, so it is better to have more than one thing, and it is also a way to appease them with copper mines that are completely useless to the baron.

"Isolde, what's on your hand?" asked Gehr as he was about to leave, when he suddenly noticed a green shiny thing in Isolde's hand, which had been in the previous few minutes.

"My lord, this is the child who fell, and as soon as I wanted to return him, he ran away. Isolde showed her what she was holding, and it was a turquoise stone.

"Malachite?"

Gehr took the stone, which was the size of an egg, rough and a little prickly, and brightly colored, resembling the green of the spots on the feathers of a peacock, which was malachite, the associated ore often found in copper mines.

This stone is produced in large quantities, and it is not unusual to find it near copper mines. However, this malachite looked a bit like a chickadee, and Gehr thought it was interesting, so he kept it.

After the survey, the group did not stop and went directly to Winterdusk Castle.

Back at the core tower, Sophia greeted her.

"Brother, everyone is together. ”
