Yue Fei responded calmly: "Brother Tian, ​​you are wise!"

"But you also saw today that the Jin army's fighting power is still intact. Our army fought with two Wanhu in the wilderness, and both sides suffered heavy losses. If the main force of the Jin army arrives, will our army be able to bomb the city in time?" Tian Shizhong was furious. "If it's too late, the main force of 60,000 to 70,000 will be overthrown by the Jin army's 14, 15, and 10,000 Wanhu here in the wilderness. Can it make the government feel at ease?"

"So we must continue to build fortifications, leaving no gaps, and not fight in the wild!" Yue Fei remained calm. "Look at the situation today. If the fortifications are complete and there are no gaps, can we defend properly?"

Tian Shizhong shook his horse for a moment, obviously understanding, but shook his head heavily: "How much cultivation do you need to achieve?"

"Simple." Yue Fei stood on his horse and pointed at the mountains and rivers. "Yuancheng is at the narrowest part of the Yellow River, only 13 or 14 miles from east to west. We have already built such a line of defense in the north, so why not build one in the south as well, and then build another line along the west river bank, and also build a line of defense on the east river bank, and connect it with Damingcheng, and by the way, sail on land again, so that the navy can run parallel along the river..."

Tian Shizhong was almost dizzy: "You might as well say that you want to build a city here to surround Yuancheng!"

"So what if it's just for building a city?" Yue Fei obviously didn't care. "Build a city with a circumference of dozens of miles, or even a hundred miles..."

"How can we defend such a big city?" Tian Shizhong was still uneasy.

"Why can't they defend it?" This time it was Yue Fei's turn to frown. "Before the freezing, if there were naval forces on both sides of the waterway, even if the main force of the Jin army arrived, it would be useless and they could only deploy their forces from north to south. But you can see the situation today. They can't deploy their forces... They can defend it as firmly as Mount Tai."

"Of course I know, the key is what happens after the frost is frozen?" Tian Shizhong laughed in anger and interrupted him directly. "How can we resist? If we can't resist, we will just put all our eggs in one basket and blow up the city with gunpowder? Aren't you most afraid of such a desperate gamble? What if the gunpowder fails... all the troops, the fortune of a country, and ten years of hard work will be ruined here?"

"This is the key." Yue Fei pointed to the huge Yuancheng in front of the two. "I asked General Zhang, and he told me that the freezing period is at most forty days, but in fact it should only be thirty days. Let's not talk about gunpowder, let's just talk about one thing... If Gao Jingshan can defend this forty-li city with a circumference of 50,000 and more than 10,000 men for fifty or sixty days, why can't we defend a city with a circumference of 100 li for thirty or forty days with 60,000 to 70,000 soldiers and 70,000 to 80,000 civilians? This place is not even as big as Dongjing City. Are our troops not as good as those imperial guards ten years ago? But didn't Dongjing City defend for several months before the people in the city surrendered?"

Tian Shizhong was speechless, but he shook his head again and again: "Even though this place has the advantage of being on both sides of the river, it is a hasty fortification. How can it compare to Tokyo City?"

"Build earthen ramparts inside to surround Yuancheng, so that the soldiers inside cannot break out; build earthen ramparts outside, build trenches, erect barricades, and set up fences; build earthen hills in the middle, set up artillery carts, divide the camps, and arrange them layer by layer... As for the logistical preparations, I also asked Tang Huai to go behind to attack the Jin army's water strongholds immediately. After 40 days of logistical preparations, it will definitely be successful." Yue Fei spread his hands in response. "Brother Tian, ​​please tell me clearly why we can't defend it?"

Tian Shizhong had a gloomy face, pinched the warhorse's mane, and said nothing.

Yue Fei knew that the other party had surrendered, but he narrowed his eyes and looked around with disdain: "To put it bluntly, we should defend the city the same way as Taiyuan and Yuancheng... Just now Gao Jingshan sent someone to tell me that as long as he is in Yuancheng, Yuancheng will not be shaken by me... I also have something to say today, as long as I set up a fort here, even the Jin army can't shake it! Let you come! I have been waiting for them for ten years!"

Tian Shizhong just looked at the other party while panting, but gradually loosened his hold on the warhorse's mane - he had never succeeded in resisting the other party once.
