After reviewing the perfect curtain call, Li Shan's work has been completed, and he can finally sleep peacefully.

In the middle of the night, Li Shan, who was sleeping peacefully, was awakened by a shout, "My lord, it's not good, the munitions department was attacked and there was an explosion." ”

"What?" Li Shan scurried up from the bed, "It's finally over, why is this happening again, and I don't let people rest." ”

Mingyue Star also hurriedly got up to serve Li Shan to get dressed, and Li Shan hurriedly went out in a hurry to get dressed and ran to the munitions.

When he arrived at the munitions, the soul chaser had arrived, and Li Shan saw that the gate of the munitions was in a mess, and there were many dead and wounded Praetorian Guards, but there was not a single assassin's body.

"What's the situation? Did you catch the assassin? Li Shan asked.

The soul chaser said angrily: "No, the number of assassins is unknown, it seems that there are a lot of people, a few of them ran away, and the rest actually detonated the gunpowder in the munitions department and set themselves on fire, and there was not a single living mouth left." ”

Li Shan was also taken aback, and hurriedly went in with the soul chaser.

Inside the munitions office, flames were everywhere, several warehouses had been destroyed by explosions, and the Janissaries were busy fetching water to extinguish the fire. But it was all flammable, and it was deliberately arson, and the fire was too big to extinguish for a while, so it seemed that it could only be isolated and waited until it burned out on its own.

"The munitions department is forbidden to patrol, and there are people you arranged to spy on it, how can someone sneak in? And let the assassin run away, and he didn't catch a single live mouth? Li Shan questioned the soul chaser.

"The Assassins are highly skilled in martial arts, and they are very popular. Originally, we wanted to catch the turtle in the urn, but we didn't expect that there would be another wave of assassins after besieging this group of assassins. As a result, we were embarrassed, allowing the second wave of Assassins to escape, and the first wave of Assassins to set themselves on fire. "The soul chaser makes his face gloomy, and he has an unshirkable responsibility for this matter.

The fire was finally extinguished, and the Praetorian Guards carried out the corpses inside, five in all, which had been charred. Completely unrecognizable.

"My day, this is too cruel to myself, I died so miserably." Li Shan couldn't help but admire these assassins a little.

"There's nothing we can do now, let's hurry up and report this matter to the emperor." Chasing souls made me a little frustrated, and this accident was inevitably punished.

Li Shan looked around and said, "Let's not be busy first, let's carefully look for clues and see if there are any clues." From what you described, it seems that the Assassins are well aware of our defenses. The guards of the Praetorian Guards are all on the surface, and it is easy to see, but your Lijing guards are secretly watching. Being able to get out of their eyes is very problematic. Could it be that they have a mole? ”

The soul chaser was also stunned, looked at Li Shan and shook his head and said, "Impossible, it is impossible for the people of Lijingmen to have a traitor." ”

Li Shan snorted and said, "There are no traitors, they can see the secret whistle of your Lijingmen, then this group of assassins is really powerful." ”

Li Shan walked into the several warehouses that were detonated and searched carefully. But the fire has burned everything, and out of the ashes there is nothing left. Suddenly, in a pinch of ashes, Li Shan pulled out a piece of cloth that had not been completely burned, which should have been left by the group of assassins. Li Shan carefully put away the fabric and wrapped it in a handkerchief.

"Do you see the weapons used by these two groups?" Li Shan asked the soul chaser.

"What do you mean? Do you suspect that these two groups of people are not in the same group? The Soul Chaser asked.

Li Shan nodded and said, "Since you said that it is impossible for the Lijing guards to have a mole." Then there is another explanation. It's just that these two groups of people are actually not in the same group. Then the second wave won't care if the first group of people will be caught, they just need to sneak in and get what they want after the first wave has distracted you. As for the first group of people, even if they were caught. It's just to help them clear their suspicions. ”

The Soul Chaser said, "Then how do you know?" ”

Li Shan showed the fabric in the handkerchief to the soul chaser, but the soul chaser looked at it carefully and didn't see the value of this thing, and asked, "What is this?" What does a piece of burnt cloth say? ”

Li Shan smiled slightly, and motioned for Li Shan to come in with him: "A piece of fabric can contain a lot of information. Look at this pile of ashes. There was no combustible material around, but it was a pile of ashes that appeared here innocently. Why is that? ”

The soul chaser looked at Li Shan with a questioning face, completely unaware of what Li Shan was talking about: "Isn't it supposed that there will be ashes when there is a fire?" ”

Li Shan pointed to several locations at the door and in the corner of the wall and said, "Look at these places. It is obvious that it is the ignition point, and there are often flammable materials in the earliest place where the fire burns, and the degree of burning is also the largest, and the traces are very obvious. And this pile of ashes, in the center of the room, indicates that someone deliberately set up another fire source here. For what? Burning something he didn't want us to know, of course. That is, something that can reveal their identity. ”

The Soul Chaser nodded and said, "That makes sense, but how can this show that these two groups of people are not in the same group?" ”

Li Shan smiled: "If you are the first group of people, knowing that you have no return, will you bring something on your body that exposes your identity?" Obviously, they didn't expect that they would be ambushed, they thought that their opportunity was seamless and they could retreat before they were negligent, and when they were surrounded and had no way to escape, they remembered to destroy the evidence. However, it was still not completely destroyed, it must have been ignited at that time, and they didn't have time to check it carefully. ”

The Soul Chaser looked at the piece of fabric carefully, shook his head, and said, "What can this piece of fabric mean?" ”

Li Shan put away the fabric and said: "Don't underestimate him, in the hands of those who know how to do it, it is not just a piece of fabric, but also a symbol that can help us find his owner." By the way, did the second group find out what they stole and found out? ”

"Your laboratory has been hacked, the materials and drawings inside have been stolen, and the material warehouse has been opened open, presumably they are trying to find a way to make gunpowder and firearms. Now that the secret is leaked, we are all responsible, and the emperor will definitely blame it. ”

Li Shan smiled: "They still underestimate me Li Shan, do they think that stealing these things can make gunpowder and artillery?" ”

"And who does Master Li think the assassins will be?"

Li Shan snorted coldly and said, "Who else can there be?" That is, the envoys of these countries. ”

Li Shan had been prepared for a long time, and the final defense was Li Shan's draft. Li Shan's manuscript is something that no one else wants to understand, and Li Shan also deliberately wrote a lot of wrong things to confuse the public, and the real draft is only in Li Shan's mind.

As for the ingredients for making gunpowder, it is actually about to be revealed. There are only three raw materials, but sulfur and saltpeter, charcoal. As the simplest raw material, it is the easiest to be overlooked, and whether they can find it depends on their own understanding.

Once gunpowder came out, it would soon become known to the people. After all, this is not a profound thing, and it is not difficult to make it, so if gunpowder is made by someone else, Li Shan will not be too surprised. The rest is the invention of firearms. In fact, this is the more technical thing.

Li Shandai concluded that within ten years, no one would be able to make artillery and muskets.

At dawn the next day, the two hurried into the palace to report the matter to the emperor. Tang Xuanzong was really angry, and strictly ordered Li Shan and the Soul Chaser to investigate the matter, and the assassin must be found within ten days.

Ten days is the day when the envoys of various countries leave, and it seems that Tang Xuanzong also thinks that the envoys of these countries are the most suspicious. (To be continued.) )
