Fifty thousand soldiers stayed behind and stood on standby. Cui Yan and several generals followed Nangong Yu for more than ten miles and arrived at a forest.

What surprised Cui Yan and several generals was that there was an ambush in the woods. The flag was filled with blazing flames showing the number of this army: Fire Army!

Moreover, Cui Yan and others also discovered the mysterious missing Nangong Yu's personal soldiers in Tucheng.

"This, this, this..." Cui Yan looked at Nangong Yu with a very horrified expression. He had never known that there was an ambush here. What was going on.

"Brother Nangong!" Seeing Nangong Yu coming safely, Qin Yuner trotted over, and the sorrow on her face turned into joy. Although Nangong Yu repeatedly promised in front of Qin Yuner that he would not have anything to return safely. However, Tucheng was attacked by the Xiqi army after all, why didn't Qin Yuner worry?

"Little Yuer, look, am I back now?" Nangong Yu pinched Qin Yuner's nose and said lovingly.

Seeing Nangong Yu and his orderly soldiers behave like this, Cui Yan immediately understood a little when he saw it. No wonder all of Nangong Yu's personal soldiers were mysteriously missing. It seemed to be to protect him, Xiao Yuer.

However, at this time, Cui Yan was not interested in the real relationship between Xiao Yuer and Nangong Yu. What he wanted to see was what medicine was sold in Nangong Yu's gourd.

"Hey, sir, cough cough..." Cui Yan touched Nangong Yu's arm.

"Xiao Yu'er, stay tuned, I have something to do with Mr. Cui." Nangong Yu briefly explained to Qin Yun'er a few words, then turned his head to Cui Yan and said, "Mr. Cui, come with me."

Qin Yun'er looked at Nangong Yu's back walking towards the depths of the woods, her eyes full of expectation. As long as the Battle of Tucheng is over, Brother Nangong will take her home. Qin Yun'er's heart is full of happiness.

Nangong Yu brought Cui Yan and others to the center of the woods, where countless mounds of soil were piled up. Some of these mounds were very new, and some had grown weeds.

In the center surrounded by countless mounds of soil, there is a very wide open space. In the center of the open space, there is a large pit with a diameter of two meters. Below the big pit, there is a cave entrance with a person high. Gao Shan and others are squatting at the entrance of the cave. Seeing Nangong Yu arrive, Gao Shan and others quickly salute: "Gourmet to the military advisor."

"Get up." Nangong Yu waved his hand, jumped out of the pit and walked to Gao Shan's side, and asked, "Captain Gao, how are you preparing?"

"Please rest assured, everything goes well, we are already preparing for the last step. We will definitely be able to complete it before midnight tonight!" Gao Shan said with an extremely excited expression. More than a month ago, Nangong Yu gave him a top-secret mission, which was to dig a hole here. Now, this hole has indeed become the most critical thing for the army to destroy the black rhinoceros beast.

"That's good, let's continue." Nangong Yu nodded slightly.

Cui Yan and others looked at the entrance of the cave in this big pit. Although they could not have imagined that Nangong Yu ordered people to dig a hole here, their impression of Nangong Yu had changed. Although when they were in Tucheng, this guy was idle all day and didn't care about Tucheng at all, it seems that this is not the case now.

Cui Yan and others also jumped out of the pit and looked towards the entrance of the cave. There was an authentic look inside the cave. Moreover, the direction of the tunnel seemed to be towards Tucheng.

"General Cui, can the military advisor be able to regain Tucheng with this hole?" A general guessed uncertainly in Cui Yan's ear.

"This is impossible. The military advisor has only been in Tucheng for a few days. Even if he secretly prepares, how long can he dig this tunnel in just a few days?" Another general questioned, looking at Cui Yan, "Elder General, what do you think?"

"I don't know either." Cui Yan frowned and shook his head, touched Nangong Yu's arm, and questioned, "Mr. Military Advisor, what do you want to do when you dig this tunnel?"

"Destroy the Black Rhino Beast Army and retake the Tucheng!" Nangong Yu said seriously.

"But, this..." Cui Yan's expression stagnated and he said in confusion: "Is this tunnel of the Military Advisor leading to the underground of Tucheng?"

"Yes!" Nangong Yu nodded.

"Bad!" Cui Yan was furious when he heard this and cursed: "Nangong Yu, I knew you were fucking bullshit. Do you think you were a mouse pangolin? In a few days, I dug out an authentic tunnel of more than 40 miles. I believe you!"

Seeing Cui Yan getting angry, Nangong Yu was not angry, and smiled happily and said, "Who said I ordered someone to dig this tunnel, it only took a few days."

"Uh..." Cui Yan's angry look stopped and he blinked his eyes at Nangong Yu, "Can the military advisor dig for a long time?"

"General Cui, when you came, you saw so many mounds outside. Some mounds were covered with weeds. Didn't you notice it?" Nangong Yu asked back.

"This..." Cui Yan was stunned. Yes, when he came just now, he was wondering why there were so many mounds of soil in the middle of the woods. It turned out that Nangong Yu had been preparing to dig a hole.

But it's not right. Nangong Yu has only been in Tucheng for a few days. How could he dig a hole in advance? Could he have calculated it correctly? One day, the Xiqi army will come to Tucheng?

If this is true, then Nangong Yu is too amazing.

Cui Yan was stunned. One of the generals beside him reacted, laughed madly, and said repeatedly: "Haha, the military advisor is such a clever plan, a clever plan!"

"A clever plan?" Cui Yan turned his head and looked at the general and asked, "Emperor Yang, what clever plan do you think of the military advisor?"

"Mr. Military Advisor must have wanted to take advantage of the night when the Xiqi army fell asleep, and then sent troops to sneak into Tucheng from this tunnel. At midnight, he launched a fierce attack, and came to the middle to catch the Xiqi army off guard. He cooperated with the attacking army outside, defeated the main force of the Xiqi army in one fell swoop and recaptured Tucheng!" Yang Duwei said with great excitement.

Cui Yan and several other generals all became very excited when they heard this. Cui Yan's old face smiled like a brilliant chrysanthemum: "Yes, yes, this plan is very wonderful!"

Cui Yan raised a thumbs up at Nangong Yu: "Mr. Military advisor is really amazing. A plan in the middle makes me admire you!"

"Blooming in the middle?" Nangong Yu did not expect that Cui Yan and the others had such idiotic ideas, which were even stupider than pigs.

Nangong Yu looked at them angrily, and said without any mercy. He cursed without any hesitation: "General Cui, what are you talking nonsense? Your subordinates are holding a chamber pot on their shoulders. Are there also chamber pots on your shoulders? You don't think about how many people can be transported into this small tunnel, three thousand? Or five thousand? You escaped into the Tucheng City, and before you could bloom in the middle, the Xiqi Army would make dumplings for you.
