Before King Rui was released from prison, he already knew that he was absolutely unlucky, so he handed over the token of mobilizing his henchmen in the frontier to Tang Huan.

Tang Huan's IQ always floats up and down the horizon, that's right.

But the only thing to be thankful for is that when Xuanyuan Wu was a fool before he was reborn, in order to instill in him to learn military books, she almost gritted her teeth and read those obscure and difficult military books.

Sure enough, I didn't understand it.

Just like the big fool at the beginning, he only understood Sun Tzu's Art of War.

However, it is enough.

With the only brain capacity he had, he came up with a method that might be useful, and then went to Huguo Temple to ask Master Yuan Hui to find the old housekeeper of the Rui Wangfu.

Give the token of mobilizing King Rui's henchmen to the butler, and then let the butler bring his words to the frontier.

There's not much she can do, but who's to say she needs to do everything herself?

Sometimes, it's just a matter of using your brain.

King Rui handed over to her the tokens of mobilizing his henchmen in the frontier, originally thinking that he could leave something enough for his most remembered daughter to protect herself.

But Tang Huan felt that she could still use the chips in her hand to skin it.

[Why do I think that you knew early on that Xuanyuan Wu was going to the battlefield? 】

The system couldn't hold back and shivered.

The current IQ level of the spicy chicken host seems to be a bit on the high side.

"Isn't it okay to be able to pinch it?"

"Do you think I've knocked the wooden fish for so many days?"

"For a person like me with a wise root, isn't it a matter of minutes to spy on the heavens?"

Tang Huan asked back aggressively, with a kind of confused confidence in his tone.

【……】

I can't afford to provoke it, I slipped away!

Its spicy chicken host has not only increased its IQ level, but also improved its mouth cannon skills!

……

The war on the frontier is fierce.

Xuanyuan Wu didn't even have time to stop longer, so he had to set off with the army.

On the day of the expedition, Xuanyuan Wu's eyes had been looking at the top of the city tower frequently, until he rode farther and farther on the tall horse, and looked back from time to time.

I'm afraid I'll miss the figure I've been looking forward to.

However, to his disappointment, Tang Huan did not appear from beginning to end.

I don't know why, Xuanyuan Wu always felt uneasy about this expedition, as if something big was about to happen.

It's an inexplicable intuition.

When he traveled thousands of miles to the frontier, he immediately sensed that there seemed to be something wrong with the atmosphere in the army.

It stands to reason that the news of King Rui's death should not have reached the frontier so quickly.

However, in the shortest possible time, the border was well known, especially after the enemy country knew that King Rui was dead, and immediately launched a surprise attack.

Although King Rui is dead, none of the subordinates he trained are vegetarians! After the previous three or four years of tug-of-war, the enemy country has long since become extremely weak!

It is impossible for the elite soldiers and strong generals trained by King Rui to defeat that group of old, weak, sick and disabled!

However, before he came, in several encounters between the two armies, the generals trained by King Rui were repeatedly defeated.

This is a very abnormal phenomenon!

And he could feel that there was obviously a resentment among the high-ranking generals in the army, although they were suppressed, but it was not difficult to find.

Xuanyuan Wu could vaguely guess what was the reason behind this kind of abnormality......
