When Yun Canglan arrived at the Royal Courtyard, the dawn of dawn had already appeared, and his handsome face was cold at this time, wearing the black armor of the chief envoy of the Shangjing Garrison Battalion, his hands were clenched into fists, and he was followed by two lieutenant generals of the garrison battalion in armor and came to Han Mo's courtyard. ()

Han Mo was like a javelin, more like a cold stone sculpture, standing under the big tree in the courtyard, watching Yun Canglan come over, Han Mo's eyes showed an extremely cold look.

Yun Canglan stepped forward and arched his hand: "General Han, you ...... Okay, right? ”

Han Mo smiled coldly and said in a deep voice: "Someone! ”

Xiao Mu immediately came in from outside the courtyard, still holding an arrow and crossbow in his hand, and came to Han Mo's side.

Han Mo took the arrow crossbow from his hand, handed it to Yun Canglan, and said coldly: "Lord Yun, you should know this arrow crossbow, right?" ”

Yun Canglan took the arrow crossbow from Han Mo's hand, his face was gloomy, and his brows were furrowed, this kind of arrow crossbow, he was naturally very clear, this was the special arrow crossbow of the Shangjing garrison battalion, and it was the most refined arrow crossbow in Qing** Fang.

Crossbow arrows are also divided into upper grade and lower grade, the cost of the cost is naturally different, compared with the bow and arrow, the cost of the arrow and crossbow is also much higher, the crossbow itself can only be owned by the military, and this kind of exquisite arrow crossbow, the conventional army is also rarely rationed, mainly equipped in the hands of the Shangjing garrison battalion.

Yun Canglan suddenly saw Han Mo take out such a refined arrow crossbow, and his face was naturally cold and terrifying.

"Assassin...... Is this what you use? Yun Canglan looked up at Han Mo and asked slowly.

The royal palace had Yun Canglan's subordinates to help guard it, and Han Mo was assassinated, so the Yan State Mission naturally asked Yun Canglan's subordinates to quickly inform Yun Canglan and let Yun Canglan rush here.

When Yun Canglan received the news, he was shocked, and he hurried here as soon as possible.

But Han Mo didn't say a word, and first took out such a refined arrow crossbow, which naturally surprised Yun Canglan very much.

Han Mo looked at Yun Canglan coldly: "Should you give me an explanation?" ”

"Han Mo, you know, the military will never do anything to you......!" Yun Canglan said solemnly.

Han Mo sneered: "The world is unpredictable, nothing will be certain. But...... Whether the military did it or not, this kind of arrow and crossbow is owned by your military! ”

Yun Canglan sighed: "This is true, but those who dare to do it to you, I am afraid it is not very difficult to get a batch of such arrows and crossbows!" ”

Han Mo glanced at Yun Canglan and said, "Yun Canglan, you are the deputy commander of the Purple Guard, I will hand over this arrow crossbow to you, you should know what it means?" ”

Yun Canglan pondered for a moment, and finally said, "That street has been cordoned off, and my people are investigating there!" ”

……

A masked dark official hurriedly came in from outside the courtyard, and when he saw Yun Canglan beside Han Mo, he stood aside and did not immediately come forward to report.

"Find out what?" Han Mo asked the dark officer.

Only then did the dark officer bow forward and say, "My lord, the little poison left between the fingernails has been put into the vessel, and it is ...... It does contain toxins, but this toxin we have never seen ......! ”

Han Mo frowned.

Yun Canglan pondered for a while, and stopped talking, but after thinking about it, he finally said, "General Han, where is the poison?" Can you show me? ”

Han Mo pondered for a moment, in fact, he didn't believe that the military would assassinate him, after all, it was not in the interests of the military to do so, and Han Mo knew better that this was Qingguo, no more than his own power in Yan Kingdom, to investigate some things here, he really needed Yun Canglan's help.

Next to the courtyard where Han Mo lived, there was a very elegant small house, Han Mo and Yun Canglan followed the dark officer into the house, and two dark officials wearing masks came forward to salute.

The doors and windows were tightly closed, and on the table, a small porcelain vase, from which the dark clerk carefully picked out a very rare particle of dust with a small silver needle.

Even those with excellent eyesight have to keep their eyes open and stare at the silver needle for a long time before they can see the fine dust on it, which is almost impossible to see with the naked eye.

Yun Canglan frowned, staring at the silver needle, staring at it for a long time before closing his eyes, as if thinking about something.

Han Mo motioned to his subordinates to put away the dust, and then looked at Yun Canglan, waiting for his explanation.

After a while, Yun Canglan opened his eyes, looked at Han Mo, pondered for a while, and finally said, "General Han, have you heard of the Golden Silkworm?" ”

Han Mo's eyes showed incomprehension.

"General Han naturally knows about spring silkworms and autumn silkworms." Yun Canglan said slowly: "That's the silk cocoon, the silk they spit out is white in color, and it can be used to spin silk." ”

Han Mo nodded and said, "What does this poison have to do with silkworms?" ”

"If I'm not mistaken, it's golden silkworm powder." Yun Canglan didn't show a very sure look, but just guessed.

Han Mo touched his chin and frowned, "Golden silkworm powder? What's that? He really hadn't heard of such a poison, so he glanced at the few dark officials next to him and asked, "Have you ever heard of this poison?" ”

These three dark officials are the officials who are better at poison in the West Flower Hall, but they all looked at each other at this time and shook their heads.

"You can't be blamed for that." Yun Canglan said in a low voice: "I only learned about this poison by accident half a year ago, and even now, I don't fully understand this kind of golden silkworm powder. Looking at Han Mo, he said slowly: "The golden silkworm is different from the ordinary silk silkworm, the silk silkworm spits silk cocoons, and the golden silkworm spits out not silk, but ...... Silkworm powder! ”

"Where do golden silkworms grow?" Han Mo thought for a moment before asking softly, "What is the toxicity of this silkworm powder?" ”

Yun Canglan said: "As far as I know, this golden silkworm is also cultivated from silk silkworms, as for how to cultivate it, I don't know, I only know that this larva needs to eat special medicines, and it has to be placed in a cold place to survive...... All in all, to breed a golden silkworm, it must cost a lot of money, and ...... The mortality rate is extremely high, and there are only one or two of a thousand silk silkworms that can be cultivated into golden silkworms. ”

Han Mo was slightly taken aback, such a rare survival rate, it was really a bit terrifying, which could indeed show that this kind of golden silkworm was indeed very rare.

Naturally, the West Flower Hall has also developed some strange poisons, among which there are naturally many poisons with extremely cumbersome development processes, but the cultivation of this golden silkworm is obviously more cumbersome than some poisons in the West Flower Hall.

"This kind of golden silkworm powder is extremely medicinal and can make people unconscious in an instant as long as it is stained with the skin...... Yun Canglan frowned: "It's just...... This kind of golden silkworm powder is too precious, and under normal circumstances, it is impossible to take it out and use it in battle. ”

Han Mo asked, "Don't use it to fight?" What is that used for? ”

Yun Canglan thought about it, and stopped talking.

"Lord Yun, my Yan Kingdom Mission will immediately question your country about this matter." Han Mo said coldly: "The weapons used by the assassins are military arrows and crossbows, as long as these arrows and crossbows are handed over, even if they are not done by the military, I think you will have a lot of trouble." So...... You and I still cooperate to find out the real culprit behind the assassin, if we can't find the real culprit, I think many people will be happy to see that the responsibility for this incident is borne by your military! ”

Yun Canglan sighed and said, "General Han, I'm just guessing, I'm not sure. The biggest use of this golden silkworm powder is...... Alchemy! ”

"Alchemy?" Han Mo was stunned.

Yun Canglan nodded and said, "Yes, golden silkworm powder is a necessary ingredient for alchemy......!" ”

Han Mo stared at Yun Canglan with a somewhat strange expression.

Han Mo naturally didn't hear the word alchemy for the first time, but he didn't understand this rather mysterious industry.

But Han Mo knew that most of the alchemists were Taoist disciples.

Taoism is divided into many factions, but the path of cultivation pursued by each faction is also different, some factions are specialized in learning the art of exorcising monsters and demons, in order to build merit, such as the Laoshan faction, and some factions are focusing on cultivating life and nourishing qi, exhaling the aura of heaven and earth to cultivate the body, such as the mixed yuan faction, the Zhengyang faction, and some are looking for the elixir in the world, and then refining it into a pill, wanting to achieve the purpose of the holy body with the path of the elixir, which is represented by the Danding faction and the Lingbao faction.

When Yun Cang claimed that the "Golden Silkworm Powder" was used for alchemy, Han Mo's first thought was naturally Taoism, and then he naturally thought of that Yuan Daoling.

Han Mo couldn't help but clench his fists, could it be that this assassination was actually planned by that Yuan Daoling behind him?

"You mean to say that this assassination is ...... Taoist priest in the back? Han Mo frowned and asked, his eyes looking extremely gloomy.

Yun Canglan was a little puzzled, "The production of golden silkworm powder is not something that ordinary people can do, and it is ...... Golden silkworm powder is very mysterious, not many people know that this medicine exists, and it is rarely used in other places except for alchemy...... If you want to kill someone, there are many poisons that are more effective than golden silkworm powder......! He frowned, he really couldn't figure it out, if he wanted to kill someone, why use such a precious golden silkworm powder.

Han Mo thought for a moment before he said: "Before the assassin assassinated, he spilled golden silkworm powder, and when he saw a golden light, a lot of dust was sprinkled on the bodies of my subordinates, but ...... I searched them later, but there was no trace of silkworm powder. This bit of dust was scraped out of the assassin's fingernails with a small silver needle......! ”

When Yun Canglan heard this, his eyes suddenly lit up, and he sneered: "In this way, the other party is pretending to be smart this time!" ”

Han Mo said: "You mean to say that he can't imagine that we can still find the remaining golden silkworm powder from the corpse?" ”

"It looks like they're overconfident." Yun Canglan said: "This kind of golden silkworm powder, I'm afraid that after it is spilled, for some reason, it will disappear quickly...... The other party must also be very confident in the golden silkworm powder, thinking that it will not leave any traces, but ...... They didn't expect that General Han would still find the residue of the drug between his fingernails! ”
