The Tartar soldiers below saw the explosion on the top of the peak, and the smoke and dust rose one by one, and they didn't know what was happening above, some people thought that there was a fire fight above, so a centurion ordered a dozen Tartar soldiers to climb up to see what was going on, who knew that just halfway up, the gravel on the top rolled down, and more than a dozen Tartars fell down in mid-air, fortunately, they fell to death on the firewood and haystacks below, but two unlucky eggs were unfortunately pierced through the belly by the branches below, and the feces and urine flowed out when they landed, making a mess.

"Light the fire and smoke it until they surrender." Bald and fierce can be seen in the eyes, Sen Ran ordered.

Hundreds of dry grass balls poured with fire oil were ignited, one by one stuffed into the green leaves and long grass and watery branches, and after a moment thick black smoke rose, and after the firewood and grass around were ignited, the black smoke billowed up, like a huge black tornado along the mountain wall, and in a moment the peak was shrouded in black smoke.

The billowing smoke made the peak dark, and the smoke and dust shrouded all the space, and in the big pit, Zhengde Song Nan and others all curled up inside, watching the billowing black smoke into the pit in horror and constantly rolling low, all of them showing horror.

The smoke and dust are getting lower and lower, and the upper end of the tunnel is already pressing down like a storm sky about to rain heavily, giving people a sense of suffocation.

Liu Jin exclaimed: "Song Nan, your method is useless, the smoke has come in." ”

Song Nan shouted: "Lower your body, don't stir the air." ”

Everyone kept lowering their bodies as the smoke sank, and finally at a foot above the ground, the smoke completely stopped sinking, and everyone lay on the ground staring wide-eyed, and the smoke and dust rolled overhead, but they couldn't breathe it into their nostrils.

Zhengde gasped and said strangely: "Song Nan, how did you know that this method was useful?" I'm really convinced. ”

Song Nan lay on his back on the ground, Dai Suer and Kang Ning buried their heads in the crook of his arm, their bodies trembled slightly, Song Nan gently stroked their backs and comforted them: "There is nothing to do, so I chatted with the emperor, has the emperor ever seen the situation of oil entering the water?" ”

Zhengde said: "Isn't that all the oil flowers on the water?" ”

Song Nan said: "By the way, it is the same as smoke and dust, oil is lighter than water, and it cannot be dissolved in water, so it will always float on water; The smoke and dust are much lighter than the air we breathe when heated, and in the enclosed part of the tunnel, they will also float up without completely falling to the ground. If it weren't for the moisture contained in the grass burned by the tartars, the smoke would not have fallen so low, and we wouldn't have to lie on the ground so wolf-bèi and sit to avoid the smoke. ”

Zhengde said: "I see, this is the first time I have heard of it, but I think there is nothing wrong with lying on my stomach, the stones in this pit are cold and pleasant, much cooler than outside." ”

Song Nan was stunned, and said in his heart: If you didn't insist on coming out to fight, at this time, you would probably be lying on the soft couch of the Qianqing Palace, eating cold melons and fruits and wine, and the palace maids around you were playing fans, wouldn't it be more comfortable than starving on this stone and lying in the rock pit with anxiety and thirst?

After about half an hour, the smoldering branches and grass below were gradually roasted and dried up, and almost at the same time a fire broke out, and the entire beacon tower was immediately surrounded by a sea of fire like Nirvana standing in the fire.

There was a crackling sound, and the stones on the fire-roasted mountain wall burst open and shattered and peeled off.

The bigger the fire, the smaller the smoke and dust, the tent cloth strip on the top of the big pit at the top of the beacon tower has already been lifted, with the steaming heat of the fire at the bottom rising, the air flow will also be all the smoke and dust, everyone climbed out of the pit, the heat around is scorching, but finally escaped the black smoke, the heat is hot, but there is no danger of life.

It wasn't until late in the evening that the fire slowly burned out, and the embers and the roasted hot mountain walls radiated a scorching heat that made it impossible to get close.

Song Nan and the others stood at the top of the probe and looked down, and saw that the lower half of the mountain wall of the beacon tower was scorched black, and they couldn't help but be secretly frightened.

"Your Majesty, everyone, you can sleep peacefully tonight, you don't have to keep vigil at night, everyone bury your head and sleep." Song Nan said with a smile.

"Yes, the stone is burning hot, the Tartars can't climb up at night, don't even think about getting cold down in one night, haha, these Tartars are working in vain." Wan Zhi laughed.

Everyone laughed, drank the last few mouthfuls of water of the day, chewed some dry food, and collapsed to the ground one by one to rest.

Song Nan didn't feel sleepy, leaning on the pit wall and looking up at the brilliant galaxy in the sky, stunned.

After tonight, it is the fifth day, trapped on this isolated island-like beacon tower, dry food and water are close to scarcity, although the Tartars have not yet been able to attack, but Song Nan understands that this isolated island can not be held at all, from the perspective of the Tartars' means today, the Tartars no longer have the hope of capturing the emperor alive, today's smoke and fire is a sign, and the later means will be even more unstoppable, and the most severe test before the arrival of reinforcements is coming.

Dai Su'er, who was snuggling up to him, moved beside him, looked up at Song Nan and said softly, "Childe, haven't you slept yet?" ”

Song Nan turned his head to look at Dai Su'er's sparkling eyes in the dark night and said, "You sleep, I think about something." ”

Dai Su'er said softly: "Do you miss Aunt Ye and Miss Lu?" ”

Song Nan nodded and sighed lightly: "Of course I want to, I don't know what happened to them." ”

Dai Suer said: "Can we live? ”

Song Nan stretched out her hand to touch her face, but she felt a little abrupt, and she retracted halfway, Dai Su'er gently grabbed Song Nan's retracted hand and pressed it on her face, and her voice was as soft as a dream: "Song Gongzi, if we all have to die here, Su'er is a little happy." ”

Song Nan's fingers ran across her smooth face and landed on the corners of her lips.

"What's so happy about dying?"

Dai Su'er said: "Of course I am happy, at least it is not that the slave family died alone, the slave family is already living alone in the world, if it is still alone when it dies, wouldn't it be too miserable." ”

Song Nan picked up her chin and leaned over to look at Dai Su'er, Dai Su'er looked at Song Nan with her head held high and looked at Song Nan without blinking, her lips were like two petals of flowers in the night, and Dai Su'er's eyes were clearly encouraging and expectant, Song Nan's heart was hot, her lips slowly approached, and Dai Su'er closed her eyes with shortness of breath.

"What are you doing?" An arm was put around Song Nan's neck, and Princess Kangning, who was sleeping on the side, woke up at some point.

Song Nan and Dai Su'er quickly separated like an electric shock.

"I didn't ...... What, Your Highness Princess, how did you wake up? Song Nan stammered.

"I was asleep, but I woke up from a dream of a big mouse." Princess Kangning leaned lazily on Song Nan's side, and said weakly.

"Where are the big rats, if there are rats on the top of this cliff, you can catch them for every meal." Song Nan chuckled.

Kang Ning gently twisted Song Nan's waist with his hand and said in a low voice, "This big rat eats people." ”

Song Nan screamed silently, knowing that Kang Ning must have eavesdropped and peeked, and came out to stir up the situation at a critical time, and changed the topic and said: "How does the wind and cold feel?" ”

Kang Ning sighed lightly and said, "It's better to be dead, I really don't know if I can return to Beijing alive." ”

Song Nan said: "You will definitely be alive, I'll pour you some water to drink, you are sick, you should take care of it." ”

Kang Ning shook his head and said: "Everyone saves drinking water, the emperor abides by the rules, and I am naturally no exception, sleep and sleep." After that, he pillowed on Song Nan's shoulders and lay down with Song Nan's waist.

Song Nan looked at Dai Su'er, her eyes were quite helpless, Dai Su'er pulled her long hair, seemed to smile, and lay down to sleep on the side.

……

On the night of the heavy rain pouring from the Tartars, Wang Yong rode his horse and galloped through the valley to the south, he knew that his responsibility was huge, and he did not dare to slack off along the way.

Because he couldn't see the road clearly at night, Wang Yong urged the horse to be in a hurry, and the horse couldn't get up after falling a few times, Wang Yong checked the horse and found that the horse's hooves had been shattered, and he must have stepped on the sharp stones on the road clearly.

Wang Yong secretly scolded himself for being too anxious, and now he lost his mount but he couldn't reach it, but regret was useless, and after drawing his sword and the result of the wailing war horse, Wang Yong took a big stride and galloped in the rainy night, and I don't know how long it took, when the sky was light, Wang Yong suddenly found that the valley in front of him had become more flat and open, and there was a faint neighing of the war horse and the sound of hurried hooves.

Wang Yong hurriedly hid in the grass and looked around, only to see a group of cavalry galloping from a distance, it was a group of Tartar cavalry, Wang Yong thought about it, and understood that this must be the Yangyuan Tartar soldiers that Song Nan had instructed him to be careful against, and they were blocking the road to Ulzhou.

More than 20 horsemen whistling and galloping to the north, after the sound of hooves was far away, Wang Yong appeared from the long grass, cautiously walked forward, it was nearly noon, the exhausted Wang Yong finally saw a walled fort standing far away on the grass in the valley in the distance, dozens of horses galloped and chased on the grass around the walled fort, and did not know what to do.

Wang Yong did not dare to approach, walked along the mountain wall from a distance, sat down to rest in a waterlogged depression, and considered a way out while eating dry food, Song Nan told himself the terrain here, in front of him was a mountain pass to the wild horse slope, out of this mountain pass to the south about fifty miles is the northernmost Black Mountain Fort in Ulzhou, and when he got there, it was a great achievement; However, the fortress of the Tartars lay in front of it, and the surrounding area was flat, and the huge watchtowers of Diao Dou stood around it, which was really insurmountable.

He has no mount now, as long as he is found by the Tartars, there is no hope of escaping, if he travels through the hillside, although he may also arrive safely, but it will take at least a few days, the emperor and Lord Song are trapped in Xinping Fort, saving people is like fighting fire, and they must not be delayed for even half a day.

Wang Yong really couldn't think of any countermeasures, and it was not a way to delay any longer, so he got up and walked slowly under the cover of the long grass, however, the last thing that happened still happened, Wang Yong suddenly saw a small group of Tartar cavalry in the distance suddenly turned their horses and ran in the direction where they were, and they were suddenly covered in cold sweat; Wang Yong hurriedly lay on the grass and did not move, but the Tartar soldiers came at a gallop with a scream, and even drew a bright scimitar halfway.

Wang Yong's heart was cold: Tartar definitely found himself.
