The 20,000 Tuyuhun and Tubo combined forces, under the leadership of the Tuyuhun prince Kachin, finally passed.

When night fell, the mountains and the moon were cold, and the surroundings were silent, only the summer insects sang in the mountains.

Li Ang and the other 500 men and horses wrapped their horses' hooves, reined in their horses' mouths, came out of the mountains and forests like ghosts, followed the road where the Tuyuhun army came, went up to Xiaojishi Mountain, and then quickly advanced along the ridge of Lazhi Mountain in the direction of Shibao.

Murong Heshun was still sent as a striker and was responsible for exploring the way. He took a hundred people to disguise himself as the Tuyuhun army, Murong Heshun was originally a Tuyuhun person, and the disguise was seamless.

The ridge of Lazhi Mountain is winding and undulating, and the two wings of the mountain are obviously asymmetrical, and the southern side of the Huangshui Valley on the north flank is shallow. The north side of the Yellow River valley on the south flank is deep and steep.

The middle and lower part of the mountain is covered with loess, and under the erosion of rain, the soil erosion in the loess distribution area is serious, and the surface appears to be broken, crisscrossing a large number of ravines. Such places can be climbed by small groups of people, but difficult for large armies to pass.

On the contrary, the top of the ridge, washed by the rain for many years, is relatively gentle, so the road to the stone fort is almost always along the ridge.

From the beginning of night, the temperature drops rapidly, the wind on the top of the mountain is very strong, whistling, as far as the eye can see, the Qinghai-Tibet Plateau in the night is reckless, barren and desolate. In the cold moonlight, from time to time, wild beasts roared in the night, and the sound was terrible.

Murong Heshun led a hundred forwards and traveled ten miles, and then encountered a Tubo outpost, similar to the small garrison of the Tang army, except that they had no city defense, and the thirty Tubo people stationed in the mountain pass set up a few tents to live in.

Murong Heshun swaggered over with a hundred forwards, and shouted in Tuyuhun dialect from a distance: "What about people? Where have all the people died? ”

The army of 20,000 led by the Tuyuhun prince Kachin had just passed. The people guarding the checkpoint listened to the shouts and did not suspect him. He also raised his voice and asked, "Which general is this?" Why turn around so quickly......."

"The general Murong Daye, on the orders of Prince Kachin......... Hey. Is this what you can ask? Less nonsense, a day of rapid marching, we are tired and hungry, and we have to rush back to deliver an urgent report, if there is anything to eat and drink, hurry up and take it out for us! Hurry up, hurry up, delay the military situation, ask for your heads! ”

The defenders were armed with torches. I could vaguely see the dress of Murong and Shun more than ten paces away, and saw that they were all dressed as Tuyuhun soldiers, and as soon as Prince Kachin's army passed, the vigilance of the people left behind was even worse.

Murong and Shun dismounted one after another, poured into the checkpoint, wanted to eat and drink, and when a hundred people secretly surrounded the remaining Tubo people, Murong and Shun shouted violently: "Kill!" ”

The soldiers of the Tang Army drew their knives one after another and suddenly struck. Cut down the Tubo people around him, and for a while the screams were endless, and blood splashed in the firelight. Some of the Tubo people who reacted quickly were shocked and hurriedly drew their swords to resist. But they found that they were already surrounded, and they were greeted by a fierce siege. Ultimately. At the cost of two wounds, Murong Heshun annihilated thirty Tubo defenders.

The first level was passed so smoothly. This greatly boosted the confidence of Leon's 500 men. Li Mi said to Li Ang: "Li Sheren, there must be ten people left. Disguised as Tibetans, they stayed here to confuse the enemy and delay our exposure.

If you want to attack the stone castle, you must be very precise in timing. The later our whereabouts are revealed, the more time we have to wait for the right moment. The best time to launch is when Dong Yanguang has just retreated, and the enemy army in Shibao is celebrating victory, and the vigilance is the most lax.

At this time, the Tubo army was eager to pursue Dong Yanguang, and it must not care about supplementing the strength of Shibao; At the same time, the enemy army in the stone fort is still in extreme fatigue and has not recovered, which is the most beneficial for us who are waiting for work!

On the other hand, once we succeed in taking the stone fort, the Tubo people will be shocked and will definitely fight back frantically. Our army was not far from being defeated at that time, and when they heard the news that the stone fort had changed hands, the three armies were excited, and they were soon able to turn back and pin down the enemy's army, so that it was unable to counterattack......"

"Wait!" Li Ang felt that Li Mi had a good grasp of the timing of the sneak attack on the Stone Castle, and he fully agreed, but he had a different opinion about the changes after the successful capture of the Stone Castle. "Li Mi, do you think Dong Yanguang will definitely come back to save us?"

After the sneak attack is successful, the Tubo people will definitely fight back frantically, in order to recapture the stone fort, there is no doubt about it, and then they will face the Tubo people from both sides, and the situation is not optimistic.

As for whether Dong Yanguang would turn back to save him after retreating, Li Ang had great doubts about this.

"Yes, Dong Yanguang knows the weight of the stone castle in the mind of the saint, if we take the stone castle, and because of Dong Yanguang's poor rescue, we will lose it, and the saint will blame it, Dong Yanguang will not escape the blame, and Ambassador Wang will not let go of this opportunity to fight back."

"No way!" Li Ang said categorically, "We can't pin our lives on people like Dong Yanguang, the stone fort is surrounded by cliffs on three sides, once we occupy it, we will be trapped on the cliff!" In case Dong Yanguang doesn't come to the rescue, we won't even have a chance to escape. ”

Li Mi can also understand Li Ang's worries, his inferences are all calculated according to normal logic, but in this world, who dares to say that everything will be logical?

Li Ang continued: "Dong Yanguang stormed the stone fort for nearly ten days, with nearly 10,000 casualties and nothing. After his defeat, our attack on the stone fort was not a good thing for him personally. Holding the stone fort will only make him appear more incompetent, and his plan for the Emperor's assault will be a laughing stock. In this case, the possibility that he will not be saved will be very high. ”

Li Yu nodded and said, "Since Li Sheren has such concerns, the best solution is to send someone back to Shanzhou in advance now, report our plan to Ambassador Wang, and let Ambassador Wang come to Shibao as soon as possible." Once Dong Yanguang is defeated, Ambassador Wang will have every reason to take command of the army, and after we successfully take the stone fort, we will not have to worry about no reinforcements coming to the rescue. ”

"Well, that's very good!"

To be on the safe side, Li Ang asked Hua Qiu to select three capable soldiers and let them send the letter to Shanzhou separately. In this way, the triple insurance is less likely to make the information undeliverable due to accidents.

Even the wise can make mistakes. It seems that he is as wise as Li Mi, and he may not be able to think through everything. This time, fortunately, the matter was discussed in advance, otherwise when the stone fort was successfully taken, it would be found that there were no reinforcements, and you could only face the crazy counterattack of the Tubo people alone, then you would cry without tears.

After dealing with this matter, Li Ang left ten people dressed as Tibetan soldiers to stay behind, and the rest of the men and horses accelerated to advance towards the stone fort. If he and Li Mi were not bad as expected, Dong Yanguang would not be far off to be defeated under the attack of the two wings of the army of Tubo.

This means that there is not much time left for Leon to do so.
