My System Is Three Thousand Years Early

Because those who had spent the most time with Qin Yanqiu were the soldiers by her side; they would be heartbroken and weakened in spirit at the news of Qin Yanqiu's death. Most likely, it would be these people who would be affected.

Therefore, to be able to control their spirits, with the idea that if you could control one person, you would control one person, most of the soldiers following Qin Yanqiu were excluded. They were not all schemed against to be killed together.

Cheng Guang only thought for a while before he felt a headache coming on.

Although the matter was a bit convoluted, he still sorted it out in a short time.

Among all the high-ranking officers of the Northern Expedition Army, aside from Duke Zhen Guo, Cheng Shiyuan, the one most familiar with Qin Yanqiu was her father, Qin Beifeng.

Who, without touching Qin Yanqiu's soldiers, could make a move on Qin Yanqiu, and without alerting Duke Zhen Guo, Cheng Shiyuan, take mental control of Qin Gaozhi and the rest of the soldiers to open the gates of North City?

It could only be Qin Beifeng himself.

But...

Is it possible?

Cheng Guang's brow furrowed lightly, and no matter what, he found it hard to believe this.

What kind of man was Qin Beifeng?

Joining the Northern Expedition Army for merely a few decades, he had established a glorious military record and was the most trustworthy person to Duke Zhen Guo, Cheng Shiyuan.

He was also one of the highest-ranking officers in the Northern Expedition Army, next to Duke Zhen Guo, Cheng Shiyuan.

A large reason why Duke Zhen Guo, Cheng Shiyuan allowed Cheng Guang to marry Qin Yanqiu was out of consideration for Qin Beifeng.

Qin Beifeng was young and, barring any accidents, was very likely to become the second Sky-Man in the Northern Expedition Army after Duke Zhen Guo, Cheng Shiyuan.

Such was the man.

Even if he did nothing and withdrew from the Northern Expedition Army, his status would still be exalted, and his future secure and worry-free.

To say he was a spy within the Northern Expedition.

Who would believe that?

Not to mention,

If Qin Beifeng really was the spy, he would not hesitate to betray his own daughter and plot against the Northern Expedition Army, betraying all the senior officers of the army.

What was his goal?

What kind of deep hatred existed between Qin Beifeng and the Northern Expedition Army, to drive him to such lengths?

At this point, Cheng Guang was truly baffled.

Based on Qin Beifeng's past behavior, Cheng Guang could not see any anomalies in him.

Qin Beifeng's respect for him was genuine.

Qin Beifeng's love for Qin Yanqiu was real.

Qin Beifeng's hope for Qin Yanqiu to win his affection after her marriage was also sincere.

If all these emotions he had shown were false,

then Qin Beifeng would be too terrifying.

Why go to such lengths?

Cheng Guang simply could not understand.

Meanwhile, even if Cheng Guang could not understand, he had to raise his vigilance at this moment.

The Princely Heir in the system task prompt had failed to discern the true mastermind, the Spy inside the Northern Expedition Army, but Cheng Guang had seen it at a glance.

Although he couldn't confirm it outright at the moment, he still had to be cautious.

He had already informed Duke Zhen Guo, Cheng Shiyuan of the potential unrest within the Great Yan Dynasty.

Duke Zhen Guo, Cheng Shiyuan might not have disclosed the full details of the situation to all the high-ranking officers, including Qin Beifeng, but he would likely instruct them to prepare for certain eventualities.

Other officers would probably not think too much about the commands of Duke Zhen Guo, Cheng Shiyuan,

But the spy would indeed realize that Duke Zhen Guo, Cheng Shiyuan likely learned some information.

What measures the spy would take in response, nobody knew yet.

If the spy really was Qin Beifeng,

His initial plan was to have Qin Yanqiu killed first, and then use some soldiers weakened in spirit because of her to take control quietly and open the city gates. The soldiers inside North City would have no choice but to fight against the Demon Beasts.

After that, he would stab Duke Zhen Guo in the back, eliminating all the senior officers of the Northern Expedition Army in one fell swoop.

But now,

Because of Cheng Guang,

Qin Yanqiu had not died.

Qin Gaozhi was dead.

What response Qin Beifeng would have next was unknown.

Cheng Guang then thought,

Qin Gaozhi was quite an important piece in the entire scheme of things; although his cultivation wasn't high, his status and authority were due to being Qin Beifeng's adopted son.

Posted on the walls of North City, he was a captain of a hundred, capable of controlling the opening and closing of the gates.

Perhaps his very duty related to guarding the gates was arranged by Qin Beifeng.

Thinking up to this point, Cheng Guang sighed with a complex look in his eyes.

If the spy had been someone else, he wouldn't have much to say, but with Qin Beifeng being the spy within the Northern Expedition Army, the problem was serious.

Whether Duke Zhen Guo, Cheng Shiyuan could accept this fact was another matter.

Even if Cheng Guang outright told Duke Zhen Guo, Cheng Shiyuan that Qin Beifeng was a traitor, Duke Zhen Guo, Cheng Shiyuan, despite his affection for Cheng Guang, would not believe it. He might even reprimand Cheng Guang for talking nonsense.

That would be awkward.

Cheng Guang rubbed his forehead with a troubled expression, unable to understand why Qin Beifeng was doing this.

With such a high status and being one step away from reaching Sky-Man in his cultivation, why would he throw away his future and insist on dragging Duke Zhen Guo and the officers of the Northern Expedition Army to their deaths?

Even though Cheng Guang was confused, he knew he had to make a decisive move now.

Duke Zhen Guo, Cheng Shiyuan could not die at this moment, as the Northern Expedition Army was a significant asset for his future. When the era of chaos came, if he had the Northern Expedition Army in hand, he might still vie for power and influence in this world.
