At the same time, in Jiulong Mountain, Yinjiang.

Zhong Yi has officially taken office and is taking the chief of staff He Wenxi to inspect the construction site of Jiulong Lake.

Standing on the top of Jiulong Mountain and looking down, you can clearly see that the entire west bank of Jiulong Lake has become a bustling construction site, with tens of thousands of civilians digging trenches and building bunkers.

Usa Mirō said something right, Zhong Yi is indeed repairing fortifications at all costs.

Not only will the gap in Jiulong Lake be blocked, but the fortifications in other directions must also be reinforced again.

In a word, Zhong Yizhen is ready to build the three lines of defense surrounding Yinjiang into an existence of iron walls. He wants to make Yinjiang truly imperfect!

However, Zhong Yi also knew in his heart that keeping the law is not a solution after all!

So looking at the construction site at the foot of Jiulong Mountain, He Wenxi brows were dancing, but Zhong Yi's brows were deeply furrowed.

Zhong Yi knew better than anyone else that there was no fortress in the world that could not be broken, and even the strongest fortress was afraid of siege. Once the Japanese army adopted a long-term siege strategy against Yinjiang, Yinjiang would not last long.

Food can last for a long time, but industrial raw materials cannot last for too long.

Without the continuous input of industrial raw materials, Yinjiang Industrial Zone will not be able to continue to produce and will not be able to continuously deliver ammunition to the troops. Without weapons and ammunition, the 10th Army and the 41st Army will not last long. At most three or five months, they will be in the dilemma of extinction of ammunition and rescue.

What's more, the old Japanese devil, Okamura, is coming.

Fang Jianwei just heard news that the Japanese base camp had made adjustments to the personnel of the 13th Army. Nishio Suzusao no longer served as the commander of the 13th Army, and Okamura Yasuji was taken over.

Zhong Yi was still very afraid of the old Japanese devil, Okamura, Nishiji.

This old Japanese man is not simple, he is a truly capable person.

Therefore, it is only the first step to defend Yinjiang. The second step is also necessary to deal with the upcoming blockade! Okamura Yanji’s best advantage is the cage policy, and he must prepare for it in the future.

At that moment, Zhong Yi turned around and ordered Xu Chao: "Achao, you can go back and have an appointment with Mr. Chang from Sanyou Industry now. I want to talk to him about the urgent matters of expanding bicycle production."

"Yes." Xu Chao turned around and hurried down the mountain.

...

Shanghai, the 13th Japanese Army Command.

Okamura Yasuji asked thoughtfully: "Usa Mikun, then how do you think the second Zhejiang-Fujian Battle or Yinjiang Battle should be fought?"

Usa Mitsuru said: "There is only one way, attack head-on!"

"Front attack?" Okamura Yanji was stunned, "Which direction?"

"Not in either direction." Hinata said disapprovingly, "Your Excellency Chief of Staff, you said just now that after the end of the Yinjiang Battle, Zhong Yi will definitely strengthen the fortifications at all costs, so the difficulty of a frontal attack will be greater. Even with the Guard Division, the possibility of a frontal breakthrough is extremely low!"

Speaking of this, Hinata Zhiming said again: "Because the fortifications built by the Chinese army on the periphery of Yinjiang can withstand the bombardment of large-caliber heavy artillery, even the 150mm caliber heavy howitzers of the Guard Division cannot explode the gap!"

Usa Mitsunobu said: "The 150mm caliber heavy howitzer cannot explode the gap, but what about the 300mm caliber naval gun?"

"300mm caliber naval gun?" Hinata said in surprise, "Your Excellency Chief of Staff, are you talking about opening the gap from the Yinjiang River Channel with the help of the navy?"

"That's right, you have to rely on the navy!" Usa Mirō said in a deep voice, "Yinjiang is a harbor city, close to the sea, and the navy's warships can go up to the Yinjiang River and reach the city center of Yinjiang. Why not use such favorable conditions? As long as the navy's warships appear in the mouth of Sanjiang, Zhong Yi spent a huge price to build the three fortification chains outside the Yinjiang River, and it became a decoration, and Yinjiang would be self-defeating!"

Hinata said: "But the Chinese army blocked the Yinjiangkou, and the navy's ships could not enter the Yinjiang River at all!"

"Then open the Yinjiangkou." Usa Mirō waved his hand, "As long as the Zhaobaoshan Fortress and Jinjishan Fortress are destroyed, the dense mine defense line of the Chinese army at the Yinjiangkou will no longer exist, and the navy's ships can drive straight into Sanjiangkou, and the Yinjiang Battle will actually end."

Hinata Shiaki said: "But the strength of Zhaobaoshan Fortress and Jinjishan Fortress is beyond our imagination. The aviation army has tried it many times, and even a thousand-pound bomb is useless."

"If a thousand pounds of bombs are not good, then two thousand pounds. If a two thousand pounds is not good, then three thousand pounds." Usa Mirō said, "There is no fortress in this world that cannot be broken. The Guishan Fortress built by Zhong Yi in Wuhan is considered strong, right? But did Your Highness Nian explode them with the Dongjiuer bomb?"

"Is the Higakure bomb?" Okamura Yanji's expression moved slightly when he heard this.

The maximum load capacity of the Japanese bomber is 1,000 pounds of bombs, and it also needs to be temporarily modified, otherwise the hanger under the belly of the aircraft will not be able to withstand this weight.

If a larger equivalent of bomb is needed, a larger load and range bomber needs to be developed, which is completely beyond their ability, because they cannot control the development of the empire's weapons, and no suggestions can be made. The consortium or chaebol that controls the development of weapons is not ordinary stubborn.

They cannot create larger bombers, but they can be modified.

They can convert the Type 96 long-range attack aircraft into an extremely large bomb!

Then a volunteer drove the attack aircraft and carried out a suicide impact on the Zhaobaoshan Fortress and the Jinjishan Fortress, which had a great chance of blowing up these two solid fortresses.

When Higakure-Miya Nihiko modified the plane, it was very simple because of the tight time, but it still easily exploded the fortress that Zhong Yi spent a lot of money to build. Now they have more preparation time and can completely modify the Type 96 long-range attack aircraft to a more perfect and powerful one!

Maybe it can really explode the Baoshan Fortress and the Jinjishan Fortress.

As long as you explode Zhaobaoshan and Jinjishan Fortress, Yinjiang will be finished.

Thinking of this, Okamura Yanji was completely moved and had to try it.

At this moment, Okamura Yasuji said to Usa Mitsuro: "Usa Mitsuk, I will hand over this difficult task to you. You can immediately call on relevant personnel to conduct detailed research on the attack and installation of the Type 96 land attack aircraft, and come up with a feasibility report as soon as possible. In addition, I will contact Gun Shi as soon as possible and ask him to transfer three. No, the six Type 96 attack aircraft will be handed over to you."

"Hayi!" Usami paused heavily, turned around and left.

Watching Usa Mitsuru disappear outside the door, Okamura Yasuji withdrew his gaze again.
