The two people who were captured alive didn't say anything, Zheng Ping's questioning was not very smooth, and Bai Liyan turned the focus of the breakthrough to the belongings of the two.

In addition to weapons and rations, the two also found three topographical maps of the eastern front drawn on sheepskins, which were extremely detailed, and where there were forests, depressions, rivers, ponds, and ravines, all of which were clearly marked. Hiding in the woods and hiding is carefully stepped on in advance, if you don't run into Lu Cheng and lead people to the field training, you can't hit the muzzle of the gun.

In addition, some kind of lemon-like fruit was found, but the taste was much lighter and the sour taste was average. Their water bladder is not filled with water, but some kind of acidic liquor mixed with apple and fruit acid.

The three-point map was scribbled with some words, some of which could be seen as place names, while others could not be seen as meanings.

"Mr. Zheng, are there any clues on these three-point maps?"

"General Hui, this map is a topographic map of Wuyang, this is a topographic map of Zhaoting, and the third is the terrain on both sides of the Dongshui River."

"Wuyang, Zhaoting! The barbarian army crossed Yesui and went to reconnoiter what Wuyang and Zhaoting were doing! ”

"General Baili, I'm afraid it's not an accident that the barbarian army appeared in these three places, and this matter should be reported to General Shutong, Master Saiqian and Mr. Su as soon as possible."

Bailiyan spread out the topographic map of the eastern line and found Wuyang and Zhaoting.

Wuyang is the city of Xuguo, three hundred miles northwest of Yesui, Zhaoting is under the jurisdiction of the Song State, it is almost three hundred miles away from the northeast of Yesui, Yesui is in the north of Duhui, more than four hundred and twenty miles apart.

The barbarian army crossed a thousand miles and ran to the rear of the coalition army to reconnoitre, even if it deliberately made a detour to attack Wuyang and Zhaoting, it was impossible to hide the scouts and beacon sentries between the four places, not to mention that all the roads that could be taken were under the surveillance of the coalition forces.

To say that a huge front can allow small units of individual soldiers on both sides to sneak through, it is impossible for tens of thousands of troops to be silent and without a trace, and it is not realistic to attack Yesui behind it.

Thinking of this, Bai Liyan asked Zheng Ping:

"Mr. Zheng, why is the Dongshui River not marked on the topographic map of our army?"

"The Dongshui River is west of Kangzhi and is not marked because it is too small."

Kangzhi is also the city of the Song Kingdom in the south, the easternmost river valley, 80 miles wide from north to south, 120 miles long from east to west, there is only one road in and out of the West Gate, so it is easy to defend and difficult to attack, but the altitude of Kangzhi is much lower, more suitable for people to live.

Eyes moved to Kangzhi, this remote city is 800 miles away from Duhui, east of Kangzhi is a grassland at a higher altitude, the air is thin and inaccessible, almost difficult to set foot in, it is a no-man's land, and what is east of the no-man's land has not been clear.

"Mr. Zheng, is there a road east of the Kangzhi River Valley?"

"The air is thin for 900 miles east of Kangzhi, and horses are still impassable, let alone people."

"And where to the east?"

"It is said that the Great Snow Mountain, which stretches for thousands of miles from south to north and is connected to the Luyi Mountain, cannot cross the large snow-capped mountains alive."

"This is strange, it is reasonable for the barbarian army to fight Kangzhi, but it is inevitable that the detour of Ye Sui will spy on Wuyang and Zhaoting. Mr. Zheng, the two men continued the interrogation, and immediately sent messengers to the three cities of Wuyang, Zhaoting, and Feiyun to inform them of the details, and Ben would immediately rush to Duhui with these three maps to discuss with Mr. Su. ”

The battle line of the coalition army is too long, there is no man's land everywhere, and it is difficult to find out how many places can pass through it, and the barbarian army will not be groundless in reconnoitering the rear of Yesui, and it is likely that a marching channel that can bypass the frontal defense line of the coalition army has been explored from the east of Kangzhi.

It was already the morning of the fourth day when he arrived at Duhui on horseback, Shu Tong and Sai Qian were not in the office, and Su Fangyi was presiding over the deployment of materials needed to repair the city wall.

"How can Young Master Yan have time to come here, please take a seat."

"Mr. Su is polite, I can't hide it, I am here to have an emergency military situation."

"Is it the marshal?"

"Six days ago, my general's subordinates captured two Jin Xuedi scouts forty miles west of Yesui, and searched from them for topographic maps of Wuyang, Zhaoting, and the Dongshui River near Kangzhi. This is a topographic map, Mr. Su, please take a look. ”

Su Fangyi took the map and spread it out on the table, confirming that it was undoubtedly a topographic map of the three places:

"General Baili is worried that the barbarian army will attack Wuyang and Zhaoting from the east of Kangzhi and bypass the back of Yesui?"

"Exactly, Wuyang and Zhaoting are weak in strength, if the relationship between Yesui and Feiyun City is cut off, Yesui and Duhui will become isolated cities, and the marshal will not be able to send troops and horses from other places to rescue in a short time."

"But the barbarian army is currently more than 1.2 million horses pressed in front of our army, not counting the unknown barbarian army advancing in the rear camp, only there are nearly 200,000 soldiers south of Duhui, and then draw troops from other places to detour to the back of Yesui, not to mention that it takes two months to prepare, one month to march, such a huge action, it is categorically impossible to hide from the imperial marshal and the pastoral division."

"What is the explanation for the barbarian army to cross our Yesui to spy on Wuyang and Zhaoting, which are at least more than a thousand miles away from the barbarian army, and the barbarian army knows the strength of our army's rear defenses?"

"Then what is Yan Gongzi's opinion?"

"Scouts should be immediately sent to the east of Kangzhi and Zhaoting, and search east at all costs. and expand the range of our army's vigilance to prevent the barbarian army from crossing our army's defense line from other places. ”

"That's good, Su immediately informed Kangzhi, Zhaoting and other places, and sent scouts to take strict precautions."

After agreeing with Su Fangyi, Bailiyan came to the east of the city to see Shutong, Duhui, Kangzhi, Yesui, and Zhaoting were all Song territory, and they were stationed in the army all year round, and they were more familiar with the local topography than Su Fangyi and other foreign aid from the Central Plains.

Bai Liyan gave the details in detail, and Shu Tong asked the local guide to inquire carefully, and the guide quickly denied the possibility that there was still a road east of Kangzhi.

It is true that there is grassland to the east of Kangzhi, but only two short months of summer show grass every year, and the rest of the time is covered with snow, and the air is extremely thin, even in summer, it is impossible to walk dozens of miles on horseback.

That is to say, to the east of Kangzhi is the snow-line grassland at an extremely high altitude, full of glaciers, a forbidden area for life, and it is impossible for large troops to pass at all.

"General Baili, the east of Kangzhi is still covered with snow, and going through this detour is tantamount to seeking a dead end, and the barbarian army will never be able to detour behind Ye Sui from here."

Shu Tong said affirmatively, Bai Liyan's attitude is still cautious:.

"That'...... It's Ben who is going to worry too much. ”

"It's not necessarily necessary to worry too much, the method of the barbarian army is different from our Central Plains, and it must have sinister intentions in sending scouts to stab behind our army, but it has not yet been detected by our army, and it is still cautious and subtle. Shu immediately gave Lu Rui an order, ordering him to step up his precautions, and General Baili assisted Lu Rui from the side to prevent a sneak attack by the barbarian army. ”

"Then General Laushu will bother!"

"Eh, the enemy is at the moment, and it is appropriate to be cautious. I don't think General Baili will leave today, how about setting up a casual banquet in the camp and having a few drinks. ”

"Yan is respectful, it's better to obey!"

"Hehaha...... Readily! ”

Affected by the region, the people of the Song State are more bold than the people of the Central Plains, although Shu Tong has more eyes, but the Song State and the Xian State and the Qi State do not have a direct conflict of geopolitical interests, and how to get rid of the Jin State is the common interest of the two countries. Suddenly setting up a banquet and entertaining is not as simple as just eating.

In the evening, Shu Tong set up a banquet in the camp of the Song army and retreated.

"Come, General Baili will taste the beef patties of my Song Kingdom, this is a delicacy that cannot be eaten in the Central Plains."

"Yan entered your country last year, is from the local to eat this kind of beef patty, it is said that after the beef loin of the calf is finely chopped, spices and refined salt are added to marinate for a day, and then add milk pastry to beat into a cake shape, put on this iron plate to fry and bake, the taste is even delicious, I didn't expect to be able to eat it in this southern border."

The beef patty recommended by Shu Tong is fifteen centimeters in diameter and two centimeters in thickness, to be exact, it is to chop the veal loin into a minced form, beat the creamy milk, and into a small amount of flour crisp, knead it into the tenderloin and beat it into a cake, and then fry the beef patty into a cake, which is a very characteristic Song cuisine, and its selection process is destined to be only the dignitaries and wealthy families can afford to enjoy this delicacy.

Eat in the mouth frankincense overflowing fresh and tender, the taste is better than the previous life of the minced meat cake more than ten times, which also added the unique rice spike grass of the Song Kingdom, the specific can not describe what kind of taste, but as long as you eat in the mouth, the special smell of the rice spike grass to stimulate the taste buds, can infinitely amplify the delicious taste of spices and various ingredients mixed together, is an important trade goods exported by the Song Kingdom.

"This cake is really delicious, and it is really rare to be able to eat it in the south."

Baili Yan praised endlessly, and Shu Tong laughed:

"In fact, the most important thing in the south is cattle and sheep, this cake can be made of beef loin, pig, and mutton can also be made, but the taste is slightly inferior."

"Hehe, this is also, although the northern Central Plains is a large land, but the population is large, all based on farming, grazing is very little, can eat pork, it is extremely rare, cattle and sheep are impossible to talk about. This person is tall and thin, the land is divided into north, south, east and west, and the customs are different, and it is difficult to weigh the advantages and disadvantages of each other. ”

General Baili is right, the land in the north is fertile and rich, but it is indeed not easy to eat cattle and sheep. Come, eat vegetables and eat vegetables......"

Shu Tong's insincere words made Bai Liyan even more convinced that there were other items at this banquet tonight.

The vegetables are all meat, and there are still very few vegetables, and it is not easy to grow vegetables in the south, which is restricted by climate and agricultural technology, and cannot grow as large as the vegetables in the mainland, and the local vegetables are short and small, and the yield rate is very low.

Vegetables are quite scarce in winter and spring, and the temperature difference between day and night in late spring and summer is large, and some vegetables cannot survive overnight and die the next day, and the coalition forces have diseases caused by vitamin insufficiency one after another. The situation of the Xianjun army was slightly better because they carried tea and bean sprouts.

After continuing to eat two bites, Bailiyan put down her chopsticks:

"General Shu, it is not the husband's doing, you and I have something to say."

"Uh...... Okay, General Baili is refreshing, then Shu will be blunt. The cavalry of your army lost nearly half of its troops, and there were still thousands of crossbows for the extra company, and I don't know if they could be sold to Shu at a price. ”

"It turned out to be for this, but General Shu won't just do it for a few thousand consecutive archer crossbows."

"Hehaha, what Yan Gongzi said is extremely true. I think this kind of even shooter crossbow is extremely convenient, if my Song Kingdom can be equipped in large quantities, the combat power will undoubtedly increase greatly, I don't know what Yan Gongzi wants. ”

"It's easy to say, it's hard to say. General Shu wanted to ask for the work of the archer's crossbow, but was this the case? ”

"Exactly" Shu Tong said calmly: "If we can make a map, our army can copy a large number of them, and it will not be good for you and me to govern the north and south in the future." ”

"Hehe......" Bai Liyan smiled indifferently, and continued: "It's not a secret, even if this crossbow is sent to the general, Song Guo will not be able to make it. ”

"Why is that?"

"The equipment required for this company to be an archer crossbow is so well crafted that the slightest mistake would make it impossible to fit the magazine in place. In addition, reeds need to be used in the arrow box, and the reeds are made of steel, which is extremely exquisite, and the steel-making method is the top secret of our Xian country, and there is no possibility of transfer, so even if the Song State obtains even the archer crossbow work drawing, it cannot be imitated.

Moreover, two years ago, the Jin Kingdom stole the work map of the even archer crossbow and the continuous archer crossbow from our Xianguo country and copied it, but the effect was far less than that made by our Xianguo. General Shu won't want to follow in the footsteps of the Jin army! ”

"Then there's no other way?"
