Night, the main hall of Sufu.

A huge map of the march hangs on the wall, with the mountains and rivers of the Sisai, the names of places, the fortifications of the city, and so on. A bamboo knot lightly clicked on the location of the Black Oil Mountain marked on the map - this is a transportation hub of the North Tianshan Mountains, 300 miles out of the Dinosaur Valley is Luntai City, it seems that the geography is very dangerous.

Su Wu looked at the map quietly and thought.

The door creaked open, and Kunlun Nu walked in with tea and gently placed the teacup on the table. Su Wu turned around, glanced at the little slave and said: "Black Oil Mountain, called the Devil's Valley by the locals, is surrounded by cliffs and cliffs, and a stone ditch in the middle. The battle of the Great Legion may not be able to be used. Li Guangli, the veteran general of the battlefield, will not fail to understand this truth, why did he choose the location of the battle here? ”

Kunlun Nu said: "According to the military situation, the main cavalry of the Huns who intercepted our army gathered in the area of Bayinbrook, Antler Bend, and Baruch, which is the terrain of the canyon, although the army is not easy to deploy, but it is conducive to besieging the enemy. Moreover, the Huns were sharp, and our army was tired. Isn't the purpose of our borrowing from the Wusun army to make General Li Ling go around behind the enemy and take a flank attack with the general Li Guangli in front of him, in order to break the enemy army as soon as possible, lead Tianma, and return to the court? ”

Su Wu nodded. Kunlun Nu said: "If that's the case, it makes some sense to choose Black Oil Mountain. ”

Su Wu sighed and did not speak. Kunlun Nu asked tentatively: "In the afternoon, the adults also talked about Tangbao?" ”

Su Wu nodded and paced slowly: "I think this Tang Bao is a little weird. ”

Kunlun Nu was puzzled: "Oh, but why?" ”

Su Wu stopped: "What is the Tang newspaper for?" ”

Kunlun Nu said: "Generally speaking, the Tang newspaper of the military department is mainly used to reflect the progress of the battle and the transportation and transportation to the cabinet, as well as to convey express reports and request reinforcements to the imperial court. ”

Su Wu nodded: "Not bad." But today's Tang newspaper is General Li Ling's report to the saint that he has led the army to borrow Wusun and secretly hide behind the enemy! ”

Kunlun Nu was stunned: "Oh? ”

Su Wu said: "This is a top secret in the army, and it shouldn't be reported to the emperor through the Tang newspaper." Moreover, usually this situation does not need to be reported to the imperial court, 'the general will be outside, and the king's order will not be affected'. It's just a matter between the generals of the unified army. In other words, Li Ling's surprise soldiers are in place, as long as Li Guangli in front is notified, the two of them can make an appointment to launch an attack. Why did you spread the word to the imperial court through the Tang newspaper? Although the Tang newspaper forwarded by Hami Post is also top secret, the secrecy is much worse after all. It's unreasonable!"

Kunlun Nu realized that the situation was abnormal, and couldn't help but gasp: "What do you mean——? ”

Su Wu smiled and said, "I don't mean anything, I just think it's a little strange." ”

Kunlun Nu asked, "Do you want to play the Ming Shengshang?" ”

Su Wu shook his head: "The Holy Lord is on the rise, it's better not to use this kind of speculation to sweep away his happiness." Perhaps, this is just my unfounded thoughts, and everything will wait until after the Mid-Autumn Festival. ”

Kunlun Nu suddenly said: "My lord, I came to you for advice. ”

Su Wu said, "Is the Imperial Doctor about medicine?" ”

Kunlun Nu said: "Exactly." ”

Su Wu said: "You might as well talk about it." ”

Kunlun Nu said: "This time I went to Luntai, cholera epidemic, the soldiers were infected a lot, I used cholera to scatter magnolia, tangerine peel, dried ginger, silkworm sand, wormwood, the strange thing is that the soldiers were basically controlled, and the people began to epidemic again, but it was useless to use its prescription, Mr. made it clear." ”

Su Wu groaned: "Since I have been apprenticed to my master Chun Yu Yimen, I have been taught by his Chun Yu Tiying, which reminds me of the trick of my husband's medicine, investigating the source of cholera, and increasing the ...... of silkworm sand drinking."

Kunlun Nu interrupted and said: "I understand, the water of the Luntai River is polluted, thank you for your teachings, when Your Majesty asked, he told me that he was not guilty!" ”

On the official road leading from Gaolan County to Chang'an, a carriage galloped in the dark night. Wei Tu Qi in the carriage urged the coachman repeatedly: "Hurry! Hurry up! The carriage roared through the fields and headed for Chang'an.

The night shrouded the silent Gaolan County, and only occasionally there was one or two barking dogs. In the quiet night, several black shadows swept across the street quickly and rushed to the front of the Baoji Pavilion. It was the four shaman messengers who followed the shaman witch god who waved their hands, and the four of them flew up and jumped over the wall and ran towards Peony's room.

The moonlight poured into the house like water, and the peony lay quietly in the curtain, and the large wooden box was placed on the ground in front of the bed. "Click", there was a soft sound in the silence, a short knife slowly inserted through the crack of the door, gently pried, the door latch was immediately inserted, "bang", the door opened, the shaman messenger flashed in and reached out to catch the door latch that was about to land, the action was clean and neat. The three people behind him immediately rushed into the room, and the four of them divided into two groups, one went straight to Peony's bedside, and the other went straight to the wooden box.

The peony on the couch seemed to be sleeping soundly and did not notice it at all.

Two shamanic messengers rushed to the bed and raised their steel knives......

Peony Khan on the couch still didn't react.

The cold light rose sharply, and the shaman's short knife stabbed into the back of Peony Khan's heart......

There was no scream, no blood, no slippery blades as they slid into flesh, and their knives seemed to be stuck in a pile of soft stuff. The two shaman messengers were stunned, and one of them stretched out his hand and gently turned the corpse over, where was Peony Khan, and in front of them was a quilt. The two of them were taken aback, and hurriedly retreated, it was already late, and they only felt their ankles tighten, and their bodies lost their center of gravity and fell forward, and the two let out a burst of exclamation.

The two shaman messengers who ran to the wooden box turned around when they heard the sound, and something shocking happened, the two shaman messengers in front of the bed had been hung upside down in the air, their hands scratching incessantly. The two people next to the wooden box looked at each other in surprise, and at this moment of lightning, the wooden box next to him slammed open, Peony Khan jumped out of the box, his hands were raised, and two bags of lime bloomed on the face of the shaman messenger, and there was a white mist in the room, and the shaman messenger screamed miserably, covering his face with both hands.

There was a sound of footsteps, and several servants rushed in from outside the door with iron guns, and smashed the heads of the two shaman messengers next to the box, and with two "ping-pong" sounds, the two fell to the ground heavily.

Peony Khan jumped out of the wooden box and asked a few servants, "Are the post guards settled?" The servants nodded: "Don't worry, we hired another carriage and found a Langzhong, and now they have got on the carriage." ”

Peony Khan nodded: "Tie up these boys, stuff them into wooden boxes, and put them in the original carriage." Let's move immediately and take a detour straight to Chang'an! ”

In front of the Su Mansion in Chang'an, a rapid sound of horses' hooves and wheels crashing on the ground pierced the silence of the night. Wei Tuqi's carriage galloped up, and the coachman pulled the reins sharply, and the horse neighed and stopped in front of the mansion. The coachman jumped out of the car, put down the pedals, and said to the lieutenant Tu Qi in the trunk: "My lord, it's here." ”

There was no answer. The coachman raised his voice: "My lord, I have arrived at Su Mansion, please get out of the car." "Still no sound.

The driver was startled and reached out to push the door of the trunk............

Yu Tu Qi leaned crookedly against the wall of the carriage, a trace of blood hanging from the corner of his mouth.

Su Wu rushed into the second hall quickly, Kunlun Nu was already waiting here, and his expression was very nervous. Su Wu hurriedly asked, "Little slave, what's wrong?" Kunlun Nu pointed to the bed and said, "My lord, come and take a look!" ”

Su Wu was stunned for a moment, walked quickly to the couch, and saw Yu Tuqi lying on the couch, his face purple and black, motionless, with a strange smile on the corner of his mouth.

Su Wudeng was stunned: "Wei Tuqi! What's going on? ”

Kunlun Nu pointed behind him and said, "This is Lord Wei's coachman, let him say it." ”

The coachman said with a sad face: "I don't know, I don't know, Lord Wei came to the county office at the beginning of the shift, saying that he had something important to rush to Chang'an overnight to tell you." It's all good all the way, and when he got to the gate of the house, the little one asked him to get out of the car, and he, he ......" The coachman cried bitterly.

Su Wu asked, "On the way, did you hear any movement?" ”

The coachman said, "I didn't hear anything, but Lord Wei urged me again and again." ”

Su Wu walked up to Yu Tuqi, stretched out three fingers to take the pulse, and let out a long breath: "There is still a pulse." Take the needle! ”

Su Tong hurriedly ran towards the inner hall.

Su Wu waved his hand at the little slave, and the little slave gently helped Wei Tuqi up. Su Wu carefully examined Yu Tu Qi's head, suddenly, his gaze stayed on Yu Tu Qi's neck, a steel needle came into view, Su Wu took a deep breath, gently lifted the steel needle with his hand, and approached the wind lamp to take a closer look, the steel needle was two minutes long, flashing blue under the reflection of the light. Su Wu sighed: "What a powerful poisonous needle!" ”

Kunlun Nu flattened Yu Tu Qi's body, took the poisonous needle and looked at it carefully. Suddenly, he gasped and blurted out, "Immortal Crane Divine Needle!" ”

Su Wu was stunned: "What?" ”

Kunlun Nu's hand trembled slightly: "My lord, you wait. With that, he walked out the door quickly. Su Wu looked at his back in surprise.

Su Tong walked in and said softly, "Master, the needle has been taken." ”

Su Wu nodded, holding the silver needle in his hand, and applied the needle all the way from Baihui on the top of Yu Tu Qi's head to Guan Yuan in the abdomen. Then, two fingers were placed on the silver needle on the Baihui acupoint and twisted gently, and suddenly there was a "cluck" sound between Yu Tuqi's chest and abdomen. Su Wu's tightly locked eyebrows immediately relaxed: "There is a door!" Su Tong, help him up! ”

Su Tong hurriedly helped Yu Tu Qi up, Su Wu's hands twisted and pulled, Yu Tu Qi's mouth opened, and with a "wow" sound, a mouthful of black blood spurted out.

A smile appeared on Su Wu's face: "There is still salvation, help him lie down." ”

Su Tong put Yu Tu Qiping on the couch. As soon as there was a knock on the door, Kunlun Nu walked in quickly, holding a small box in his hand.

Su Wu stood up and wiped his hands: "Little slave, what did you just say?" ”

The little slave said: "Do you remember the Crane Divine Needle?" ”

Su Wu was stunned: "Immortal Crane Divine Needle? ”

The little slave raised the wooden box in his hand: "This is it." ”

Su Wu nodded: "Yes, yes." Just now I used a silver needle to treat the poison for Wei Tuqi, and I also faintly felt like this, this scene seems familiar...... "Suddenly, a few years ago, in Ganquan Palace, the scene of treating the wounds of the military beard of the pseudonym Boss Li jumped in front of his eyes, and flashed through his mind......

Kunlun Nu looked at Su Wu and said softly, "Remember, what he said?" ”

Su Wu took a deep breath, took the wooden box, and gently pushed it on the side of the box with his right hand, and with a click, a row of Immortal Crane Divine Needles stood up, Su Wu gasped, and said softly: "It's really Immortal Crane Divine Needle...... What's going on, what's going on? ”

Kunlun Nu said: "Could it be a coincidence? ”

Su Wu shook his head: "There are very few real coincidences in this world, and every seemingly coincidental thing must be closely related to it." Why did Wei Tuqi come here overnight, and what did he have to tell me? And who would have killed him in the same way he had done so many years ago? There's a lot of work in this! Oh, by the way, little slave, is there anything on Yu Tuqi's body? ”

Kunlun Nu shook his head: "I have checked it just now, but there is nothing." ”

Su Wu pondered for a moment, then suddenly raised his head and said, "Where is the carriage that Yu Tuqi was riding in now?"

Kunlun Nu said: "It's right behind." “

Su Wu said: "Let's go, go and see." ”

The carriage was parked in the backyard yard. Su Wu and Kunlun Nu walked quickly, the little slave pushed the car door, Su Wu looked inside by the light of the lantern, and the carriage was empty. Su Wu took a deep breath and pondered intently, and suddenly, his eyes lit up.

Kunlun Nu asked, "My lord, what did you think of?" ”

Su Wu didn't speak, he stepped into the car, sat in the place where Wei Tuqi had sit, and said to the little slave outside the car: "Little slave, if you are a murderer, where will you hide in this carriage so that no one will find out?" ”

Kunlun Nu pondered for a moment and said, "Get off the car." ”

Su Wu nodded, his gaze looked down the ground of the carriage, and a little red cloth caught his attention. The cloth is hung at the rear of the carriage in a direction from the bottom up. Su Wu hurriedly got up, gently removed the cloth, and examined it carefully.

Kunlun Nu said: "My lord, what is this?" ”

Su Wudao: "This is most likely the cloth stripped off the murderer's clothes." Little slave, look under the car. ”

Kunlun Nu lowered his body, put the lantern under the car, and carefully inspected it, when suddenly he let out an exclamation: "My lord! Su Wu hurriedly leaned down. Kunlun Nu pointed out: "Look." ”

The rafters at the bottom of the car were cut by a quick knife with two handles. The little slave said: "The murderer must be hiding under the car, and after the car leaves Baoji, he will get out of the car, open the back door, and enter the car." ”

Su Wu nodded: "Not bad." With such skills, it can be said that it is easy to kill Yu Tuqi. But why didn't he just kill Yu Tuqi and the coachman and throw the corpses into the wilderness, but he must let the carriage come to the gate of Sufu and let us see this scene? ”

Kunlun Nu nodded: "Yes, I also think this matter is very strange." It's illogical! ”

Su Wudao: "What often seems illogical is actually the most logical. If the murderer just wanted to kill Wei Tuqi, then he didn't have to act like that. Therefore, it is now at least certain that the phenomenon we are seeing is diametrically opposed to what actually happened, and the murderer did not want to kill Yu Tuqi! ”

Kunlun Nu thought about it and nodded slowly.

Su Wudao: "According to this conclusion, he must have to get something from Yu Tu Qi?" So, what does he want? ”

Kunlun Nu said: "Maybe it's a thing." ”

Su Wu nodded: "Well, a good hypothesis, and the most likely outcome." He smiled and continued: "Okay, let's just say that what the murderer wants is a thing, so there is such an inference: when the carriage left Baoji and entered the official road, he suddenly appeared, but he found that the thing was not on Yu Tuqi's body. So, he used various means to force Yu Tu Qi to hand over this thing, but Yu Tu Qi refused to hand it over, so in desperation, he had to shoot and injure Yu Tu Qi with the Crane Divine Needle......"

Kunlun Nu said disapprerovingly: "In this case, why didn't he just kill Brother Wei?" ”

Su Wu said: "You ignored the premise we just mentioned, he didn't want Yu Tu Qi to die." ”

Kunlun Nu was stunned: "Having said that, but why?" ”

Su Wudao: "Maybe Wei Tu Qi has a more important role for him; Moreover, the reasoning we just made is not the only conclusion. So, what is the best outcome for what is happening right now? He paced slowly, Kunlun Nu looking at him quietly.

Su Wu said softly: "The carriage stopped in front of the mansion gate, but Wei Tu Qi was highly poisoned but did not die, and the coachman was unscathed...... Suddenly he stopped and raised his head, "Could it be so?" ”

Kunlun Nu said softly: "My lord, what did you think of?" ”

Su Wu looked at the little slave with a smile on his face: "Although it is unbelievable, it is the most reasonable inference." Little slave, I'm glad you thought of the Crane Divine Needle, otherwise ......"

Kunlun Nu wondered: "My lord, what do you mean ......?"

Su Wu shook his head: "It's just reasoning now, you can't say it, you can't say it." In my opinion, everything will have to wait until Yu Tuqi wakes up. ”
