The Turkic side's reaction to the battle of Yuanni Nashan greatly exceeded the expectations of Li Che and others, and Yongyu Lu heard Duan Da explain to him the reason for the rejection of the battle, and immediately expressed his willingness to return the corpses of the fallen soldiers of the Sui army without landing, and assured Duan Da that the Great Khan would never destroy the status quo of the two countries' strikes and repairs because of this misunderstanding, and asked Duan Da to bring a letter to Yang Guang, and the regular meeting between him and Yang Guang was still going on as usual.

When Duan Da returned to Bingzhou to report to Yang Guang, Zhang Wei and Wang Shao had already gone to supervise the troops in the border states, and only Li Che was sent by Yang Guang to listen to the details of Duan Dayu Chen's trip to Baidaozhou to negotiate with Yongyu Lu.

"Lord Wang, the last general thinks that it is not yet possible to judge the final attitude of the Turkic side towards the battle of Yuanni Nashan." Li Che listened to Duan Da's courtesy, got up without hesitation and said, "Right now, Sha Bolu has not returned the army leading the army to the west, and Yongyu Lu, as a Turkic prince, his identity and status are still under Kehedun, no matter what, he will not change the status quo of the two countries' military strikes and repairs before his father leads the army back to Dujin Mountain." Yongyu Lu's promise to General Duan Da to return the bodies of the fallen soldiers and maintain the regular meeting with the prince is likely to be his strategy of delaying the army, and only after his father Sha Boluo learned of this and then reacted accordingly, can it be confirmed whether the battle of Yuanni Nashan will become an excuse for the Turks to raise troops to attack and change the current status quo between the two countries. ”

Li Che's judgment was based on the various news that had been sent out of the customs for several days, and did not simply rely on the one-sided words obtained by Duan Da when he went to Baidaozhou to meet Yongyu Lu, so Yang Guang decided to adopt Li Che's advice and continue to make active preparations for the battle, and at the same time, he ordered Duan Da to lead people to contact Yongyu Lu to retrieve the bodies of the fallen soldiers as soon as possible and bury them thickly.

"Tell the Turks that General Yukura's body must remain intact." Yang Guang specially instructed Duan Da before leaving, "At the same time, in the process of contacting the Turks, you must try to find out the name of the Turkic general who led the army to ambush Yuannina Mountain, and report it to me." ”

"Lord Wang, at the end of the past few days, I will repeatedly think about the before and after the battle of Yuanni Na Mountain, but I feel that something is not clear, and I do not shy away from taking the liberty and want to tell the prince." Duan Da listened to Yang Guang's explanations, and did not rush to retreat, but said to Yang Guang in a hesitant manner.

"There's nothing to say, there's no need to babble."

"The last general has been thinking for the past few days that most of the troops stationed at Yuannina Mountain received the news in advance that our army was about to go out of the pass and attack Yuannina Mountain, so they set up ambushes in the back mountains and mountain passes to lure our whole army into depth, and then attacked back and forth, hoping to annihilate our army in the mountains. Otherwise, even if they were stationed in the back mountain and the mountain pass in two ways on weekdays, they would never let go of the vanguard led by General Yujuluo and would not fight until the prince and the last general led all the men and horses into the mountain. Please think twice. ”

Yang Guang carefully recalled the experience in Yuannina Mountain that night, and the more he thought about it, the more he felt that what Duan Da said was reasonable, and he couldn't help but be vigilant, and asked Duan Da: "Could it be that you suspect that someone leaked the news to the defenders in Yuannina Mountain in advance, which will cause our army to be surrounded in the mountain and suffer heavy losses?" ”

"After thinking about it for many days, I still can't rule out this possibility." Duan Daping was always sleek and alert, but he was not decisive enough and responsible, and once Yang Guang asked him to give a clear answer, he became cautious.

"Well, I'm aware of this, and I'll arrange for someone to find out. You must not reveal the information until the mole has been identified. ”

After Duan Da left, Yang Guang sat alone in the main hall of Jinyang Palace, and repeatedly recalled the situation before he led the army out of the customs many times, and finally locked the target of suspicion on two people: the abbot of the Daxingguo Temple in Bingzhou, Hui Lin, and reported to him, claiming that Yu Wenyue was placed in Yu Xiaoren of Yuanni Mountain.

Yang Guang can clearly recall that after he learned the whereabouts of Yuwen Yue from Yu Xiaoren, he had mentioned Yuanni Na Mountain to the monk Huilin after visiting the Daxingguo Temple to offer incense, as if there was Duan Da present at that time. Monk Hui Lin told himself at the time that Yuannina Monastery was also one of the Buddhist temples outside the Guanwai that he had raised funds to build, and since he had lived in the territory of the Guanwai Turks for many years, who could ensure that he was not secretly instructed by the Turks or Yuwen Prajna to lurk around him?

Except for Monk Huilin, Yang Guang really couldn't remember who he had revealed to anyone that Yuwenyue was placed in Yuanni Mountain. Then, the way to leak the news is very likely to be on Yu Xiaoren.

Yu Xiaoren since he returned to Chang'an at Mengjin Ferry on his own orders to send a message to his eldest brother Yang Yong, and then stayed in Chang'an for half a year due to illness. It stands to reason that he should not doubt whether Yu Xiaoren is loyal to the imperial court, but considering that except for himself and Yu Xiaoren (including the scout who found out that Yu Wenyue was placed in Yuannina Temple), there is really no possibility that anyone else will leak the news, Yang Guang can only temporarily list Yu Xiaoren as one of the objects of suspicion.

On the same day, Yang Guang secretly summoned Li Hun to come and personally explained to him the relevant matters related to the investigation of the traitor, and asked him to focus on the investigation of Monk Huilin and Yu Xiaoren, and sent someone to monitor their every move.

Although Li Hun and Yu Xiaoren were classmates and friends when they were too young, they didn't dare to slack off at all because Yang Guang asked him to lead people to investigate the traitors, and he didn't care about the friendship with Yu Xiaoren's classmates, so he returned to the hussar camp and immediately arranged competent manpower to closely monitor Monk Lin and Yu Xiaoren.

Ten days later, Duan Dajing negotiated with the Turkic side and brought back as many as 112 corpses of hussar battalion soldiers who died in the Yuannina Mountains from outside the pass.

Three days later, Yang Guang personally presided over the burial ceremony for more than 100 hussar battalion soldiers who died in Yuannina Mountain, and announced in public: All the fallen soldiers have been recommended to the emperor and rewarded them for their promotion, so that they can enjoy the honor of mourning after death. The hussar battalion was personally presided over by Li Che for the lack of posts in the first battle of Yuanni Nashan, and those who were loyal and brave and good at fighting were selected from the army of the state capital.
