The four people caught in Zhong Xuan's Mansion were all daughters, and the four were locked up in four cells. Cao Shuang saw the person behind Yu Bin holding a wooden box, the workmanship of the box was very exquisite, and it was covered with patterns. Cao Shuang leaned in very curiously, "General Yu, what is this?" ”

Yu Bin saluted Cao Shuang, and then smiled slightly, smiling a little unnaturally, "It's just an ointment used to interrogate prisoners." ”

Ointment? It wouldn't be that there would be a truth elixir in this era, then this would be too against the sky. Cao Shuang secretly thought in his heart, only to see the person holding the box take out a small box similar to rouge from the wooden box, and there was a very pungent smell after opening the lid. The man went into the cell, dipped his finger in some ointment from the small box, and someone pressed the female prisoner so hard that the man reached between the female prisoner's legs and wiped it, and then the female prisoner was tied to a stake.

After applying the ointment, the female prisoner's face was ruddy and her breathing was short. Cao Shuang had already guessed what kind of ointment it was, and the old man blushed and withdrew from the cell. Standing outside the cell, the sound of humming came into his ears, and Cao Shuang was even more sure of his guess. Not long after, Yu Bin came behind Cao Shuang with the interrogation record.

"Done?" Cao Shuang is most concerned about the information in their mouths now, and as for what tricks to use, he can't care about it. A cat is good if it catches mice, and sometimes intelligence determines the course of a war.

Yu Bin nodded, "Yes, all of them have been recruited." It turned out that the four of them were when Zhong Xuan first arrived in Chang'an, and when they recruited people, they lurked in Zhong Xuan's mansion. It has been lurking for years, and in recent days, it has been activated. Because Zhong Xuan is cautious and strict in governing the family, they have never had access to core secrets.

"Tomorrow according to what is written on this paper, let them send it to Ma Chao in their way." Cao Shuang handed Yu Bin a piece of paper and continued to ask, "You often use this method to interrogate female prisoners?" ”

"I don't use it very often, and although I can't get it on the table, it's the fastest way." Yu Bin smiled embarrassedly.

Cao Shuang nodded and walked out, "To do this errand is to do whatever it takes." Cao Shuang's heart was full of helplessness at this time, this is the sadness of these spies, they can't show their true identities, once they are exposed, they will face all kinds of torture, those people yesterday are like this, and the same is true of these today. Cao Shuang understands that in this kind of troubled times, his soft-heartedness should not appear.

In the early morning of the second day, in a small courtyard of a private house in Chang'an City.

"General, you see this is a carrier pigeon that flew in this morning." When Yu Bin saw the carrier pigeon, he immediately sobered up. Take out a piece of cloth from the bamboo tube on the pigeon's paw. Looking at the text on it, Yu Bin's head was bigger, and the text on the cloth was neither Qiang nor Chinese characters. Yu Bin put down the sweat towel in his hand to wipe his face, and shouted to his subordinates, "Go and bring that girl to Lao Tzu." ”

It turns out that the text on the cloth is ancient Qiang, and only a few people still use it. At the beginning, Ma Dai used the ancient Qiang language to transmit information in order to prevent the intelligence from being intercepted by the enemy. If it weren't for the exhaustion of Ma Chao's internal response in Chang'an City, I'm afraid that Yu Bin would still be worried about understanding what was said on the cloth at this time.

Ma Chao sent a letter to inquire about the situation in the city and the situation of the Yin and Zhao families. Yu Bin asked people to translate the paper left by Cao Shuang into the ancient Qiang language, and then sent the information to Ma Chao in the way that Ma Chao should have responded. After listening to Yu Bin's report, Cao Shuang breathed a sigh of relief, he should have made all the preparations, and the rest depends on whether Ma Chao can take the bait.

The distance from the Ma Chao military camp outside Chang'an City to the city was not very far, and after a short time, Ma Dai received a reply. Without delay, Ma Dai sent the cloth to Ma Chao. Ma Chao looked at the cloth and showed a subtle smile. Ma Chao smiled and patted the cloth on the table, "Zhong Xuan ordered to collect money and grain from various families, and recruited troops to defend the city, and there was a conflict with the Yin family. ”

"Big brother, this is Liang Xing and our people from the horse play camp." Ma Dai took out another piece of cloth in his arms and handed it to Ma Chao.

Looking at the cloth in his hand, Ma Chao's face suddenly became ugly. Pound leaned forward, "Major General, what's wrong?" ”

Ma Chao threw the cloth in his hand into the brazier in the tent, and said in an unkind tone, "The night before, there were two people from Chang'an who had been secretly spying on Liang Xing for a long time. Later, the two escaped from Liang Xing's camp, but they didn't mention it. ”

"Do you mean they have taken refuge in Cao Cao?" Pound's eyes narrowed, and a hint of murder flashed in his eyes.

"It's not impossible." Ma Dai continued Pang De's words, "Big brother, do you think we are postponing our plan to attack Chang'an?" ”

"No, you know the situation in our army very well. If we don't take Chang'an in a short time, we will have to withdraw our troops. Ma Chao's face softened slightly, as if thoughtful, "For us, this is an opportunity." Even if it's a trap, you have to jump inside, but before that, we have to let Liang Xing pick it first. Before Ma Chao arrived, Zhong Miao moved the grain and people outside Chang'an City to Chang'an City. Ma Chao also thought about getting some food from nearby counties or villages, but the actual situation made Ma Chao dumbfounded, what could be taken away was taken away, and what could not be taken away was burned. After these days of consumption, food has become the shortcoming of the Xiliang Army.

Several carriages, escorted by bad people, drove into the Taishou Mansion through the back door. "Cao Gongzi, Yin Ke and Zhao Kuan's closest relatives are here." Yu Bin jumped down from the carriage and reported the situation to Cao Shuang and Zhong Xuan. Bringing Yin Ke and Zhao Kuan's close relatives into the Taishou Mansion was nominally to protect them, but in fact they were used to threaten Yin Ke and Zhao Kuan. It is about the entire Chang'an, Cao Shuang and Zhong Xuan have to be cautious, and every step must not be wrong.

"What if Ma Chao doesn't take the bait?" Xiahou Yuan spoke first, this was a small temporary meeting before the war.

"If we don't take the bait, we will have to defend Chang'an." Cao Shuang took two sips of the tea in front of him and continued, "According to the intelligence, the food of the Xiliang Army is already insufficient, and even if the deception is not successful, they will not be able to surround it for a few days. ”

"The old man still knows a little about Ma Chao, he is more conceited, young and frivolous, and always wants to do something big to prove himself. Ma Chao is ambitious, and the old man thinks he should come. Zhong Xuan stroked the beard under his chin and said.

"Then we will prepare with both hands, in short, we will defend Chang'an City first." Xiahou Yuan ended this short pre-war meeting with a word, as a military general, he still has a lot to do, no matter whether Ma Chao is in the plan or not, Chang'an City will eventually be defended by those who are soldiers.
