"Your Highness truly made this old man feel ashamed, Ling Shu Institute hasn't had any success in creating anything of use for several years now," Zhang Feng Han shook his head mockingly. "This useless immortal man could only sit and eat salary. I had intended to request the Emperor for retirement next year. Unexpectedly, we were met with a national disaster, perhaps I will not be able to die of old age."

Chang Geng gently said: "Master Feng Han's contributions will last for a thousand years; you must not belittle yourself."

"A thousand years...will there still exist a Great Liang after a thousand years?" Zhang Feng Han pursed his lips. "I had thought as I entered Ling Shu Institute, I would no longer need to pay attention to the outside world, dealing with fire engines and steel armor for the rest of my life, concentrating on doing my own work.

"But the bustling world turned out to be too crowded. Even if the righteous and the villains went their own ways, they would always come across each other. The more you did not want to entangle with anything, the more you wanted to do something outstanding, the more you would end up doing nothing — even if one only wished to be the lower class with their hands stained in oil."

Chang Geng smiled and remained quiet, he knew Master Feng Han was only expressing his feelings and did not want to hear his reply.

At this stage, the contradiction between the imperial power and the military power of two generations was unquestionably the fuse, but it was not the most fundamental reason — the long-term illness of the gradually emptying Treasury had doomed them to this bleak end.

Zhang Feng Han said: "Every day, the piers of the anti-air net are being adjusted. Now the foreigners only dare to drive, a large number of their Eagle Armors dare not to go up, but the strength in the hidden piers is still limited. I've heard that foreigners use ropes to 'fly the kites' outside the city every day. I'm afraid that in a few days, the iron arrows stored in the hidden piers will become unsustainable. What should we do then? Does Marshal Gu have any plan?"

In total, there were fewer than 100 Black Eagles in Northern Camp, including those missing an arm and a leg. If the anti-air net would fail, perhaps that would be the time when the city would break down.

Chang Geng: "Mm, he knows, he's trying to find a way out."

Zhang Feng Hen who was full of concern, upon hearing this, did not know whether to laugh or cry. He wondered whether he should say that Yan Bei Wang was a 'hero raised from youth', or whether he should say that he was slow-tempered. It seemed that even if the sky collapsed in front of him, the little prince would only reply with 'I know' as if it had nothing to do with him.
