"Tang Yun?" The next morning, Guanyin saw Tang Yun who came over on the city wall, "Aren't you supposed to be staring at the North Courtyard Palace, why did you come here?" ”

"Lin Xi is keeping an eye on me, he asked me to send you a message, he found the tunnel in the second hall of the North Courtyard Palace, but he doesn't know where it leads, and he wants you to help see if there are any suspicious places around the imperial city."

"Authentic? What else was found? ”

"By the way, he also said that he saw a lot of workers moving a bunch of big boxes into the tunnel."

"Boxes?"

"Yes, I heard it the other night, it's been three days."

"This big box must be something very important inside...... Ah! The two of them unconsciously scattered as they spoke, and as they walked, Guanyin suddenly stepped on a loose stone and almost fell, but fortunately Tang Yun helped her.

"Princess, watch your step."

"It's been this place and it's been here." Guanyin took a look, and the two of them were about to walk to the west city wall, which was the city wall that had collapsed before, although it was quickly built again, but the stones on it were still a little loose.

"Princess, go back. Princess? "Guanyin was on the city wall, and his eyes caught a glimpse of a strange building, the gate facing the city wall, more like a warehouse.

"Tang Yun! Look at that warehouse-like room, I think it's a little strange. ”

"That'...... It looks like a warehouse. ”

"Go down and have a look!" Guanyin recognized that there must be something strange about that warehouse.

This warehouse is not small, the warehouse is locked, and there are government seals.

"Guarded by officers and soldiers?" Tang Yun grabbed Guanyin and pointed to the door of the warehouse, where two people were guarding in the clothes of officers and soldiers, looking like they were from the government.

"Strange, I remember that there is no official warehouse here, but what is the matter with this officer and soldier......"

"Princess, are you sure this is not a warehouse for government supplies?"

"Absolutely sure, the warehouses where the official family stores materials are all in the north of the city, and there are absolutely none in the west of the city."

"We'll go back in the evening."

The two waited until the soldiers guarding the door began to doze off, and then they emerged from the alley and went around the back of the warehouse. One of the two dragged the two officers and soldiers directly into the back of the warehouse, and the one in Tang Yun's hand was directly wiped on his neck, so frightened that the other body trembled like chaff, if it wasn't for the mouth being covered to death, I am afraid they would have shouted out loud.

"If you tell the truth, I will spare your life, if you don't tell the truth, I will let you end up with him!" Guanyin threatened.

"Yes, yes, yes... I'll tell you the truth! ”

"Who told you to guard the warehouse here?"

"It's... The king of the North Courtyard, Yelu Sogo! ”

"When was this warehouse built?"

"Probably...... It was built half a month ago. ”

"What's in the warehouse?"

"This... Woman, I don't know, I'm just a gatekeeper......"

"Again, to be honest!"

"Don't, don't! Grandma, grandma, don't use the knife, I really don't know......"

"Do you have the key to the warehouse?"

"Yelu Sogo said that this warehouse doesn't need a key, he can go in directly!"

"Authentically?" Tang Yun and Guanyin shouted out in unison.

"It looks like this is the exit of the tunnel, and the workers have moved all those boxes here."

Guanyin glanced at Tang Yun meaningfully, Tang Yun immediately understood, and wiped the man's neck with a sharp knife.

"Take off your coat and take it away, throw the body on the south street, and let the government dispose of it."

"Yes."

"You must let Lin Xi know... cough cough cough ......"

"Princess, did you have another cough?"

"Don't worry about me... When this matter is resolved, I will go to treat it, cough cough ......"

"Okay......"

……

"Asking Tang Yun to call us over in the middle of the night, is there anything important?" Lin Xi received a message from Guanyin, did not dare to hesitate, and rushed to the west of the city in the starry night.

"This warehouse was built by Yelu Sogo, and I think there must be the answer we want."

"Don't have a key?" Lin Xi looked at the keyhole on the door.

"No, I think the tunnel in Yelu Sogo's Mansion leads here, so he didn't even think about letting people open it after he locked it."

"Is there wire?" Lin Xi asked.

"This ...... No. Guanyin Tang Yun looked at each other.

"I have." When Yanshou heard this, he took off a silver hairpin.

"It's about the same thickness, and it can be used." Lin Xi kissed Yanshou lightly on the face, "Little girl, when this matter is over, I will buy you another five." ”

"I want ten!" Yanshou blushed, and it was really life-threatening, so Lin Xi had no choice at all, "Okay... Ten is ten! ”

"Hey, get down to business first, and there's outsiders." Guanyin raised her hands speechlessly and rolled her eyes.

"Yes, yes, yes... Get down to business first. Lin Xi broke the tip of the hairpin, tentatively reached into the keyhole and turned around, feeling that the problem was not big, so he found a good position and turned it hard, "click", the door should have been pried open.

By the light of the moon, the three of them opened the door of the barn, and at the same time a gust of wind wafted by with a strange and unpleasant smell. The walls of the warehouse are very thick, and the interior walls are even all made of iron sheets. It was full of large boxes, with only a gap about a person's width in the middle.

"Ahem, ahem... This smell ......" Guanyin smelled the smell inside and lost control for a while, and coughed violently.

"Are you alright? What happened to you? Lin Xi hugged Guanyin, who was coughing violently, and asked with some concern.

"This, this is the smell of gunpowder......" Guanyin finally spit out a few words, and there was a dry cough.

"Tang Yun, take care of her, I'll go in and have a look."

Lin Xi looked at the box in the warehouse, stabbed it gently, and found that it was a cloth bag, the knife pierced into the cloth bag, Lin Xi pulled it out, and there were dense small black dots stuck on it, Lin Xi showed it to Guanyin, and asked, "Is this gunpowder?" ”

“…… Be! ”

Lin Xi's eyes lit up, and he turned around suddenly: "The gunpowder in this warehouse is tens of thousands of catties, once ignited, it will inevitably cause a huge explosion, and the walls on both sides are made of thick iron plates, which will cause all the energy of the explosion to rush out of the gate, and the gate is so close to the west city wall, it is easy to blow up the city wall, and then, they will rush in through the gap and go straight to Ouchi!" ”

"Ahem...... Now it seems that this is the most likely explanation. ”

"You guys stay outside for a while, and I'll go in and see if there's a secret passage."

Lin Xi drilled into the gap, and these people deliberately left a path in the innermost part of the warehouse, which should be where the secret passage is located.

Lin Xi knocked on the ground and made sure that it was empty underneath, but he couldn't find a mechanism to open the secret door.

"How's it going, have you found the secret door?"

"There is a secret door inside, that's for sure, but it should only be opened from the North Courtyard Grand Palace. So -- we're going to wait for them to leave. As long as they leave the Great Palace, it means that the plan has begun, from the palace to the west city wall, it will take ten minutes, and we need to assemble the Praetorian Guards including the outer city in advance to ambush in the Great Interior, and use their explosions as a signal, just wait for them to rush into the Wende Palace, and all the Janissaries can rush out together, surround and kill them. ”

"Understood, Tang Yun continued to go back to monitor, and I immediately went to the queen mother to ask for an edict so that I could mobilize the Praetorian Guards in the surrounding inner and outer cities."

"When all the preparations are done, it's time for them to take the bait."

……

"All preparations are ready, and when we go to court today, it will be the day we are waiting for the summit!"

"With these more than 1,000 soldiers who have taken the Five Poison Powder, even the Praetorian Guard is no match for us."

When the first rays of the morning sun shone on the earth, the last battle began—
