The man in black hummed and said, "Be careful, let's follow Ma Biao's footprints to be the safest." He thought about it and asked Helan Xue, "Girl, do you have screen powder on you?" ”

Helan Xue was slightly stunned, took out a small bag from her body, and said, "Only this one." ”

The man in black also pulled out a bag, checked it and said to himself, "Let's give it a try." He handed the pearl to Helan Xue, and with a wave of his hand, a handful of powder had already drifted out and fell to the ground, slowly, a faint light appeared on the ground, and in the light, two rows of shallow footprints emerged, which was the direction of coming and going. The man in black said with joy: "Girl, it's done." ”

Yang Jiulin sighed in his heart, what the hell is this? There is still such an operation. What is this? Helan Xue and a few people followed behind the man in black, walking inward little by little, and when the glowing fan was almost invisible, this person raised another wave, so that he barely walked for about two pillars of incense, and there was no way in front, and at the end of a few steps, a stone gate blocked the front.

A few people are not in a hurry to go out, according to the direction just now, this is about the lead to Yuguan, and there is a section of downhill, after walking for a while, and continue to go up, Yang Jiulin is worried, afraid that it is the moat that passes, because of the fear of the organ, a few people are careful to go, and it is much slower, so now it is not sure whether they have gone out of the city, and which is outside the city. The man in black carefully approached the ground, listening to the sound outside, his eyes suddenly became extremely shocked, waved to them, and whispered: "Run!" ”

Several people have been careful in advance, seeing his reaction, they quickly ran back, the man in black had already put the night pearl into his arms, the secret passage was dark, only the glow powder on the ground was faintly bright, a few people did not dare to be careless, ran back, ran not far away, the ground behind him sounded, rolling down a boulder.

it! Helan Xue couldn't help but scold softly, the man in black saw that the situation was not good in the end, turned around and put his hands against the boulder, and said to Helan Xue: "Girl, let's go, they want to seal this passage, I think Ma Biao is dead, and the mother Gu has a sense." The subordinates delay for a while, and you go quickly. ”

Helan Xue said to Yang Jiulin: "Brother Jiulin, you go, I'll help him." ”

Where is Yang Jiulin willing to follow her, the man in black hurriedly said: "Girl, there are still boulders behind, if you don't leave, we won't be able to leave, the life of the subordinates is originally the master's, and the girl will not hesitate." ”

Helan Xue thought about it slightly, took out the long whip on her body, her wrist was forced, and with a bang, the whip handle had been nailed into the wall, and with another shake, the whip was also nailed to the other side, just stopping the boulder at the waist, she pulled the man in black and said, "Go quickly." ”

A few people jumped through the narrow passage, but fortunately there was no mechanism in the passage, and a few people kept changing positions with their footsteps, so they didn't dare to stop following the fluorescence. In a blink of an eye, he ran to the bottom of the slope, and there was the sound of a boulder rolling down behind him, obviously the long whip had been broken, and several people did not dare to delay, and continued to run inward, until the terrain began to rise before daring to slow down, the sound of falling rocks behind him had stopped, and only the faint sound of impact was heard in the passage. A few people let out a sigh of relief, and the man in black took out the pearl again, and the light in the secret passage was restored, and he walked for half a stick of incense before coming back to the entrance of the cave.

Outside the entrance of the cave, Yang Chenglin and the others were anxious, what happened after being in for so long? Will there be danger. Ma Biao has died violently, isn't it very dangerous for them. In a hurry, the man in black had already taken the lead in coming out of the secret passage, and then Yang Jiulin and Helan Xue also walked out of the secret passage. Several people looked at each other without saying a word, closed the secret passage, and went to the study together.

Not long after they went down, Ma Biao suddenly died, there was no scar on his body, and the Gu worm on the back of his neck also turned into a black mark. Helan Xue and Yang Jiulin looked at the corpse on the ground, and couldn't help frowning, Yang Jiulin waved his hand: "Let's see if there is anything wrong with my head." ”

Wen Shuang did not hesitate, directly took out the dagger and shaved off Ma Biao's hair. Sure enough, on the back of his head, there was a black pinhole, and if you didn't look closely, it would be a mole. The warm cup is carefully cut with a silver knife, and a thin needle is carefully picked out with the tip of the knife.

Yang Chenglin said hatefully: "After all, it's a step too late, and there are still spies in the city." ”

Several people have sunken faces, who will this person be? Yan Wu patted He Lanxue and Yang Jiulin and said: "It's almost dawn, you guys have also tossed for a night, let's go to sleep first, and let's think about countermeasures tomorrow." ”

Back in the room, in the dark night, a man in black fell silently from the roof, this person's voice was very low, and said: "Girl, Ma Biao was stabbed to death by a poisonous needle blown with a bamboo pole." The person is slightly shorter than the little marquis, and he is also thinner, and the person's body is extremely fast, when the subordinates found out, they couldn't catch up, and only saw a back, and the subordinates didn't startle the snake, he went in the direction of the south of the city. ”

Helan Xue snorted and said, "If you see this back again, can you recognize it?" ”

The man hesitated for a moment and nodded: "Although I am not completely sure, it will not be too bad." ”

Helan Xue said: "Then you should pay attention to it in the army these days, and let them pay more attention to whether there are people in the army who knock on the side to inquire about the news, and there are people who speak with a slight Beidi accent." I heard that voice with a bit of a Beidi accent, not from Beidi, and I also lived there. ”

The man fell, and his figure flashed, and he was gone.

This matter was quietly put aside for them. Early the next morning, after breakfast, everyone went to the council hall again, but they were shocked by what they saw, and saw that in the hall, there was a huge table, which was fenced with wooden planks on all sides, and the table was full of sand, models, which were made into different shapes, hills, rivers, and those models were towns, passes, and camps scattered everywhere. The generals were amazed, what the hell is this? If you look closely, isn't this the terrain and defense map of Beihai and its surroundings? The location of their own side and the Beidi camp is clear.

"General, this is great, the layout of the enemy and the enemy is clear at a glance."

"What's it called? This seems to be much clearer than the map. ”

“……”

Zhang Xin and Liang Dabao stood at the table with smiles and looked at Helan Xue with an inviting face.

Helan Xue yawned and winked at them, which was a response: Well done.

Yang Jiulin turned to Helan Xue and said, "Ah Xue, what is this?" ”

Helan Xue smiled and didn't sleep enough, and said lazily: "This is called a sand table, I asked the fifth brother and the sixth brother to arrange it according to the map, you can see if there is anything wrong, and then adjust it, so that we will look more intuitive and convenient." She said a little shyly: "I really don't like to look at the map, the flat looks like I have to make up for it, it's too tiring." I'm lazy. ”

Yan Wu slapped her on the back of the head and said, "You have a lot of ideas." ”

Yang Jiulin exclaimed: "What other surprises do you have to give us?" ”。

Helan Xue said proudly: "You can't think of more." Tell me how we are going to regain lost ground. ”
