Gu Liubai was slightly stunned. He had read countless files of the border army and also knew from Liang Fengning that countless fortresses on the border line of the Tang Dynasty.

Baicaoyuan is also called Shishui City. It is a fortress on the northwest border of the Tang Dynasty. It is also the fortress that the Tang Dynasty border troops have fought the most times with foreign enemies and killed the most people to date.

Now, Baicaoyuan and the Jiuqu land, which once belonged to the actual control area of ​​the Tang Dynasty, belong to Tubo.

Long before Zanzhuo's rise, the border troops and Western Turks of the Tang Dynasty repeatedly tug-of-war in this area, and the Nine-Curve Land and the fortress here changed hands many times. The terrain of this fortress was extremely evident, like a large tree stump erected in the wasteland. To attack the city, it is not as simple as climbing the city wall, but first climbing a steep mountain, and then facing the city wall and defending troops.

This is a round mountain. Apart from some white weeds, there are no trees growing in the surrounding mountains.

Around this city, every battle will leave behind tens of thousands of corpses.

In Qinghai Head, no one has collected white bones since ancient times, so what we are talking about is here.

Local herders called this round city a cursed city. They said that the white grass and flowers were transformed by ghosts who could not return home. In the wind and sand, the dead soldiers were still fighting, and the sound of bones hitting and weapons hitting were heard in the wind.

"You were all Baicaoyuan's defenders?" He looked at Zhang Shengnian and asked seriously.

Zhang Shengnian nodded and said, "Twenty-seven years ago, Baicaoyuan was in the hands of our Tang Dynasty. Thirteen years ago, although Baicaoyuan was once captured by the Turks, it was soon taken back by the Tang Dynasty. For the thirteen years, the border troops of the Tang Dynasty have been guarding Baicaoyuan."

His eyes fell on the corpses of the white-haired old men, "The most of us were guarding Baicaoyuan for thirteen years, and the least of us had been guarding for nine years. In the most difficult battle to defend the city, we resisted the 50,000 enemy troops and were trapped for a month and a half. The grass in the city that didn't even eat animals was eaten by us, but we still defended that battle."

Gu Liubai took a deep breath and said, "A battle with the Turkic Iron Blade."

Zhang Shengnian closed his eyes with some pain and said, "Even if we live in such a purgatory, we still guarded that city. My chief Qu Jianan smiled and disappeared as he smiled. We don't know whether he starved to death or was exhausted. But a city protected by countless heroic souls was buried in the conspiracy of the powerful. Twenty-seven years ago, we lost that city and only sixty-one people lived."

Gu Liubai frowned slightly and said, "If I remember it well, it was the Tuqi Shi tribe and the Western Turkic coalition that captured Baicaoyuan. At that time, there were more than 5,100 defenders, and the coalition was more than 20,000. The logistics supply troops were defeated by the Tuqi Shi cavalry. I did not see any obvious abnormality in the military records. Are you a person who experienced it personally? What is the conspiracy you mentioned?"

"I remember the battle twenty-seven years ago so clearly?" Guo Que and Lu Letian couldn't help but look at each other.

Zhang Shengnian also looked at Gu Liubai with some shock. He swallowed his saliva with difficulty and said slowly, "The military should not record that Gai Xin'an led 8,000 troops and horses to ambush near the beacon tower. It should not be recorded that the day before the army of Tuqishi attacked, the pool used for water storage in Baicaoyuanli was poisoned. It is impossible to record that the food that should have been sent three days ago was not delivered until the army of Tuqishi arrived."

Gu Liubai shook his head without any emotion and said, "The military files I have seen are indeed not recorded. Who do you think it was done later? Do you think it is Duke Pei?"

Zhang Shengnian looked at Gu Liubai and said, "Ga Xin'an is the Duke Pei Guo's man, and the food has not been delivered for a long time. Later, it was confirmed that it was an order from the military to change the route of the grain transport team. The person who issued the military order was Pei Jiang, who was also from the Pei family."

After pausing, looking at Gu Liubai who was thinking seriously, Zhang Shengnian swallowed the wounded medicine and gritted his teeth, "Later we found out that even Bai Caoyuan's governor was a member of the Pei family. In the original case, General Siqing saw that it was impossible to defend it. He wanted to abandon the city and break through, but Pei's governor stopped him and wanted to defend Bai Caoyuan to death. After the fourteen days of persistence, Tuqishi and the Western Turkic coalition forces broke through Bai Caoyuan and slaughtered everyone in the city. However, according to the information we later verified, the governor himself broke through the siege with more than ten monks on the eve. After that, there was no record of the military's governor, and this man seemed to have disappeared out of thin air."

Gu Liubai said calmly: "If you want to do such a thing, you will definitely seek some great benefits. Since you have come and checked it carefully. In your opinion, why did Duke Pei do this?"

Zhang Shengnian said: "Because of King Jing."

Gu Liubai was stunned and subconsciously turned his head to look at Shen Ruoruo.

Only then did he realize why Shen Ruoruo was a little strange when he heard the word "White Grass Round".

Zhang Shengnian naturally didn't know that the middle-aged aunt in front of him was the famous Princess Jing.

He looked at Gu Liubai and said, "The King Jing was investigated. It was from that time that Wen Siqing, the general stationed in Baicaoyuan, was the King Jing's man. After Baicaoyuan City was broken, the military information provided by the military showed that the soldiers in Baicaoyuan wore ordinary leather armor. The three thousand rhinoceros leather armors that should have not feared the sword were unknown. They were transferred to the crowd. After all the parties investigated, they found that the King Jing's man directly replaced the expensive rhinoceros leather armor with ordinary leather armor. Then they involved King Jing's large amount of greedy military funds.

When he was in charge of the generals in the goulian army secretly raising the private army, he finally found out that King Jing set up a magic circle to steal the fortune of Li's true dragon. King Jing immediately lost the qualification to compete with the other princes for the dragon throne. In the battle between the dragon throne of the previous prince, Pei had always bet on the current emperor. So in our opinion, Pei deliberately lost the Baicao round and the Nine Curved Land, which was a trick of killing two birds with one stone. Not only could King Jing step down, but it could also allow many generals who had been linked with King Jing to be punished, thereby controlling a large amount of military power."

Gu Liubai said seriously, "How could you survive the massacre at that time?"

Zhang Shengnian said expressionlessly, "The pond in the city was poisoned, and there was no drinking water. Some of us could only dig wells day and night. At that time, we were in the mentality of trying it out, and wanted to dig into the mountain to see if we could find some drinking water sources. Coincidentally, the day before the city broke, our shaft collapsed, and all of us were trapped in the well pit. The army massacred the city, and no one found that we were still alive. Fortunately, there was no drinking water source in the city. After the enemy slaughtered the city, they could not station in the city. They left the city and continued to move towards the Tang territory. We spent several days to save ourselves successfully. We all felt that the reason why we survived was not our luck, but the ghosts of our colleagues who died in battle were blessing us."

"I will definitely find out this matter and give you an explanation to your colleagues who died in battle." Gu Liubai said this first, then looked at Zhang Shengnian and said seriously, "But just hearing what you said, there is something unreasonable in this matter. Or, you think it was done by Duke Pei, and if you believe that he is a sinner, just what you said, there are already great doubts here."

Zhang Shengnian was stunned and said, "What's the doubt?"

"Whether it is delayed in transporting food and grass or poisoning in the water, it is a superfluous move. Think about Duke Pei's nickname. If it was his plan, it would not be like this." Gu Liubai smiled faintly and said, "According to the military situation I know, this enemy army was ambushed near the beacon tower. Although the losses were heavy, the ambushed army itself suffered extremely heavy casualties. The Tang army can only be regarded as a miserable victory. According to your later inference, if Duke Pei was a plan to kill two birds with one stone, he would sacrifice Baicaoyuan to bring down King Jing, and at the same time, he defeated the thunder cavalry and Shihe

The Western Turkic army came to obtain a large amount of military merits, and thus arranged for more people under their command to occupy the high positions of the military. The correct way should be to let Baicaoyuan drag for ten days and half a month, which would cause heavy losses to the Tuqishi and the Western Turkic coalition forces to suffer heavy losses and extremely tired. Then, not only will the ambush be more likely to obtain battle results, but also in my opinion, if this ambush Tang army had been waiting near the beacon castle as you said, they could even cross the Nine Curves Land, and even directly plunder some of the Tuqishi's territory."

Zhang Shengnian frowned unconsciously, and he suddenly felt it made sense.

Gu Liubai continued, "And according to the time you mentioned, the biggest doubt is that Duke Pei of the State Council did not have the ability to cover up the sky with the military at that time. He could not reveal some flaws and try to cover it up. He wanted to prevent water poisoning, food delivery delays, and army ambushing in advance. His ability at that time could not be done by him. And according to my opinion, even if he could do it, he would not do it. Because if a truly smart person has a very simple method, why should he choose a method that is particularly complicated and has many hidden dangers that need to be covered?"

After Zhang Shengnian took the injury medicine, the medicine power started to run, and there was already a bloody color on his face, but at this time his face quickly turned pale. He looked at Gu Liubai, "When we have been tracing for so many years, may it be that someone misled the clues?"

Gu Liubai looked at him and said seriously, "It's not just misleading, it's probably being used. Whoever lets you stand at this mountain pass in the end is probably the culprit of the fall of Baicaoyuan back then."

Looking at Zhang Shengnian who was speechless, Gu Liubai bowed and bowed, saying, "It's just that these are just speculations, but please believe me, I will find out clearly."

Lu Letian was solemn about it.
