Who understands? He traveled through time with a high-spec spatial ability.

Qiao Jingjing's eyes lit up, and she clapped her hands in praise, "That's a great idea! The mountainous terrain is complex, perfect for an ambush. However, you need to arrange the positions of the ambush troops carefully, so they don't expose themselves prematurely."

Tantai Zhou nodded, "I will make the arrangements. Jingjing, you can share any other ideas you may have."

Qiao Jingjing thought for a moment, then pointed to a valley on the projection and analyzed seriously: "You just mentioned that we should pretend to retreat. I think this strategy is a bit inappropriate. The Tongguan army has easily captured three cities in just two days, which is unprecedented! Their morale is high now. If we suddenly retreat under these circumstances, everyone will be suspicious."

"If it were you, what would you do next?" Tantai Zhou looked at Qiao Jingjing with great interest, wanting to hear her insights.

Qiao Jingjing lowered her head and pondered for a moment before slowly saying, "In my opinion, the strategies we used when we launched the surprise attack on Tuoba Zheng and attacked Hancheng and Pengcheng are probably no longer applicable. After all, Tuoba Jun isn't stupid; he certainly won't stumble in the same place where Tuoba Zheng fell. Therefore, my suggestion is that we take the initiative and launch a mutiny. Look here..."

As she spoke, she projected a nearby map. Since the last upgrade, the space had gained an additional function: projecting a 3D real-world map for Qiao Jingjing. However, this function was extremely time-consuming, and she rarely used it.

She pointed to one of the places and said, “There is a place that must be passed from Xiangcheng to the capital. From a high place, you can see that the mountains on both sides are steep and the mountain range rises abruptly from the ground. All around is flat land with no obstruction and an unobstructed view.”

Her voice was clear and melodious, yet carried an undeniable certainty.

"Therefore, I conclude that the clear stream canyon in the mountain crevice is the best ambush site. If the enemy sets up an ambush here, we will be put on the defensive. But from another perspective, if we can set up an ambush here first, we can seize the initiative and deliver a fatal blow to the enemy!"

Tantai Zhou gazed at the Qingxi Canyon projected on the screen, a hint of admiration flashing in his eyes. He couldn't help but feel deep respect for Qiao Jingjing's keen insight and decisive decision-making.

"Jingjing, your analysis is insightful and exactly what I was thinking. Then let's set up an ambush here in Qingxi Canyon and catch the enemy off guard!" Tantai Zhou's words revealed his trust in Qiao Jingjing and his confidence in the ambush.

His brow furrowed slightly as he cautioned, "However, since Tuoba Jun anticipated the ambush here, he must have taken precautions. We must be careful and not let our guard down."

Qiao Jingjing smiled confidently and said, "That's exactly what I wanted to say. We can first send small groups of troops to operate near the canyon, deliberately creating openings so they think our forces are scattered. At the same time, our main force will split into three groups and move in three directions."

The first and second teams were hidden on the peaks on either side of the canyon, while the third team lay in ambush at the canyon's exit. Once they entered the canyon, they would first cut off their retreat, then attack from both sides, trapping them in a dilemma.

Tantai Zhou nodded slightly. "This plan is excellent. In this way, they will only have one way to go: rush forward. And the exit ahead has been controlled by our army. It's like catching a turtle in a jar."

“These are all just our guesses,” she said with a calm smile. “We can’t be too idealistic, after all, the situation on the battlefield can change in an instant. If the enemy has the same idea as us, then we won’t be able to use our numerical advantage to win a quick victory. Also, the narrowest part of the canyon can only accommodate 10 people passing by side at the same time, and we need to prepare for this in advance.”

After hearing Qiao Jingjing's reminder, Tantai Zhou secretly admired her caution and thoroughness.

He glanced at the map again, various different plans flashing through his mind, but the specific details still needed further communication and discussion with other generals.

Tantai Zhou looked at her approvingly, "With your help, I am more confident in this battle."

The two meticulously considered all possible scenarios, both favorable and unfavorable, pondering and carefully weighing each one. Qiao Jingjing felt she had never been so serious before, working even harder than she had before the college entrance examination.

Neither of them expected that their near-perfect deduction would be useless, as Tuoba Jun did not set up an ambush in the canyon as they had anticipated, rendering all their previous plans futile.

Moreover, Tantai Zhou advanced with unstoppable momentum, conquering Qinglan City, the next stop after Xiangcheng, with remarkable ease.

Taichu Hall

The palace was so quiet you could hear a pin drop. The Emperor Yan pinched the bridge of his nose with his withered hand, with only one personal eunuch beside him.

"Baoshun, what's that noise outside? It sounds like a lot of noise to me."

Bao Shun bowed and said, "Your Majesty, this servant will go and see immediately." He then turned to leave.

At this moment, a voice came from afar: "No need, Father. Let me report to you what that noise was."

Upon hearing this, the Yan Emperor raised his head and looked in the direction of the voice, only to find that his vision was blurred and he could not see the person clearly. However, he recognized the voice as that of his third son, Tuoba Jun.

The Emperor of Yan's face lit up with joy, and he asked loudly, "Is that Jun'er? You've returned so quickly, could it be that the surprise attack was successful?"

Tuoba Jun was dressed in a black outfit, with the same gilded and silver-inlaid curved sword hanging at his waist. His steps were steady and powerful, each step showing great composure.

He drew closer and closer, finally reaching the Emperor of Yan.

Bao Shun stood aside, keenly aware that the Third Prince's behavior was somewhat unusual, but for a moment he couldn't figure out why.

He had no time to think deeply, so he quietly moved a few steps closer to the dragon throne, just in case.

Tuoba Jun raised the corners of his mouth slightly, looking at the Yan Emperor with a half-smile, and said slowly, "Father, don't be anxious. Why don't you calm down and listen carefully to the sounds outside? Doesn't it sound like a palace coup?"

Emperor Yan stared wide-eyed at Tuoba Jun in disbelief, and cried out, "What did you say? Protect me! Protect me! What are you waiting for? Quickly escort me away from here!"
