On the day Cao Cao arrived in Tianshui, Zhang Baiqi was ready to attack Tongguan. At this time, it was lying in ambush in the path near Tongguan.

"Strategist, when are we going to do it?" Ma Dai has been here for half a month, and the terrain near Tongguan has been thoroughly explored, and he is already a little impatient.

"Don't worry, Cao Jun's fleet is about to arrive at Tongguan, and we will do it again when the time comes." Zhang Baiqi pressed Ma Dai, smiled, and signaled Ma Dai not to worry, in the evening, the ship can arrive, and then raid Tongguan, which is the best time.

"No!" Ma Dai arched his hand and shook his head helplessly, I really don't know what Zhang Baiqi has in mind, but my brother told him to obey Zhang Baiqi's orders, and Ma Dai has no choice.

As soon as night fell, Tongguan City fell silent. Except for the sergeants who were on vigil, the rest went to rest. After years of conquest, Tongguan was basically devoid of residents, and only the defenders were stationed here. In the Taishou Mansion, Guo Jia is studying countermeasures and how to guard Tongguan.

"Strategist, it's so late, why don't you have to eat?" Zhu Ling saw that the light in Guo Jia's room was still on, so he came in to take a look, and saw that Guo Jia had not eaten yet, so he kindly reminded Guo Jia.

"Wenbo, don't worry about when I went south and north with Lord Sikong, Bufan and I often went out to fight tooth sacrifices, eat less, eat more, there is no big problem." Guo Jia waved his hand and signaled Zhu Ling not to make a fuss, Zhang Baiqi has not acted yet, which makes Guo Jia feel uneasy, it was a silent night before the storm.

"By the way, Wenbo, where did Mancheng go? Why don't you see him? Guo Jia seemed to have thought of something. glanced at Zhu Ling.

"The military advisor is relieved. Mancheng went to inspect the castle tower. Man Cheng is cautious by nature, and he usually has to go back and forth many times, so it's a little late, and the military advisor doesn't have to worry. ”

"By the way, there is nothing wrong with our army's beacon, right?"

"The military advisor can rest assured that the subordinates of the beacon tower have sent heavy troops to garrison, and everything can be guaranteed." In order to prevent Zhang Baiqi's tricks, Guo Jia ordered people to be in Chang'an City. On the outskirts of Chang'an, Tongguan built three high beacon towers, the purpose is to Tongguan defenders, Chang'an defenders, and roast goose armies rely on each other, forming a triangular trend, one side is in difficulty, the two armies rescue, and each other is the offensive and defensive trend.

"Okay, let's go. We also went to see the city defense, and Mancheng also worked hard. You go and order the sergeant to prepare a roast pig, and we will go and bring some food to Mancheng. Guo Jia threw away the carving knife, rubbed his head and didn't come up with the purpose of Zhang Baiqi, only to relax and slow down.

"No!"

"Man Cheng, Wenbo and I are here to bring you a roast pig." Guo Jia took Zhu Ling and the roast pig to the city tower, and as soon as he saw Li Dian, he began to joke.

"Strategist?"

"The last general has seen the military division."

"Man Cheng doesn't have to be polite, you and I are both old men who have been raised by Chen Liu, no matter what official position you have today, I will send you pork."

"Thank you, Brother Fengxiao!"

"Wenbo, give a pig's foot to Mancheng."

"Yes, Strategist!" Zhu Ling cut off a pig's foot and handed it to Li Dian.

"Man Cheng, is there anything unusual about today's inspection?"

"Back to the military division, there is nothing unusual in today's inspection, the wounded soldiers and damaged weapons that have returned from the front line of Chencang have been brought back, and the final general will be transported back to the armory in Xudu after the inventory is prepared, and handed over to the craftsmen for repair." Ancient iron tools are very valuable, bows and arrows will be worn out after a few uses, and swords will be the same, after a long time, there will be gaps, become blunt weapons, and they must be repaired before they can continue to be used.

Li Dian pointed to the Weishui tributary not far away, where Cao's transport ships were unloading discarded weapons and wounded soldiers and heading to the treasury in Tongguan.

"Strange, how can these ships be so light?" Guo Jia looked at the transport ship and was stunned for a moment, if the whole ship was loaded with iron tools and wounded soldiers, the draft must be very deep, but the draft of these ships was only half of the hull, could it be that the ships were not transporting iron tools?

"Strategist, what's wrong?" Li Dian saw Guo Jia's puzzled eyes, could there be something wrong with those ships?

"Mancheng, call the sergeants who transported them, I have a few words to ask them."

"No!"

Soon, Li Dian came to Guo Jia with two sergeants who were transporting, and the two saw that Guo Jia did not salute, and seemed to be very strange to Guo Jia.

"Strategist?" Li Dian arched his hand, see Guo Jia.

"Strategist!" The two also followed Li Dian to salute Guo Jia.

There must be a problem with these two sergeants. Guo Jia looked at the two sergeants carefully, his eyes flickered, and he didn't dare to look directly, which was a sign of a ghost in his heart.

"Who are you two from, and whose subordinates are they?"

"The two subordinates are from Yanzhou, and they are the soldiers of General Xiahoudun, and because they were slightly injured, they were sent by the general to General Xu Huang's account to be responsible for backup transportation." The two replied to Guo Jia respectfully, and there was no problem with the accent, the authentic Yanzhou pronunciation.

"General Xiahou's subordinates? By the way, General Xiahou's eyes are not good, and he left an old problem when he conquered Lu Bu, as long as the weather warms up, the injured left eye will become painful, I wonder if General Xiahou is sick? Guo Jia looked at the two of them vigilantly.

"Pain? I'm afraid the military advisor is mistaken, although General Xiahou is blind in his left eye, but he has not been ill for a long time, there is no old trouble, I don't know if the military advisor is mistaken? The two looked at Guo Jia suspiciously.

"Haha, it may be that I have been busy with official business recently, and I am a little confused, General Xiahou has nothing to do, it is General Xu Huang who has something. All right, go down. Guo Jia patted his head, could it be that he was too careful?

"No!" The two of them arched their hands, and they were about to retreat.

'The heavens are dead!' Guo Jia said four words inadvertently, and the footsteps of the two soldiers stopped.

"Hair Hill!"

With two clicks, the heads of the two soldiers were twisted off.

"Strategist?"

"Manchester City, Wenbo, quickly gather the soldiers, and Zhang Baiqi's men have infiltrated Tongguan. Immediately close the gates of the city and search for the spies in the city. Guo Jia immediately reacted, Zhang Baiqi had already made a move, and his Tongguan had been targeted.

"Zhang Baicai's sergeants have turned into transport soldiers of our army, and they must be strictly examined."

"No!"

"It's on fire, it's on fire!" Suddenly, a soldier pointed at the beacon and shouted.

Guo Jia and the three of them looked at it, the huge beacon tower was burned, the smoke was everywhere, and the billowing black smoke could be smelled even on the city tower, and the Xiliang army actually raided the beacon tower.

"The enemy army is attacking the city, there are enemy troops!" Suddenly, a Xiliang cavalry appeared under Tongguan, it was javelin cavalry, ready to attack the city with javelins.

"Manchester City, lead people to search for traitors in the city, Wenbo, I will defend the city with you." Guo Jia had long been prepared for the surprise attack of the Xiliang army, and immediately ordered Li Dian and Zhu Ling to act separately.

"No!"

Hundreds of miles away in Chang'an City, Zhong Xuan saw the beacon tower in Tongguan, and immediately gathered the army and rushed to Tongguan with the roast goose king, even the beacon tower was burned, how could the military situation not be urgent?

Zhong Xuan's army had just left Chang'an City, and Ma Chao, Ma Teng, and Han Sui appeared outside Chang'an City with the main force of the Xiliang Army. (To be continued......)
