Wu Nai, who suddenly wanted to die and looked at the golden box mechanism, stared at Bai Yu expectantly.

Bai Yu is not a person who is very good at rejecting others, he asked with some embarrassment: "Brother, ...... They all said that they were dying, so why did they have to hit the south wall......"

Wu Nai replied: "Think about it, we obviously touched this stone platform just now, but there was no reaction? I wonder if the old fox is lying to us." ”

Bai Yu asked suspiciously: "Do you doubt that the Prime Minister will deceive us......?" I don't quite understand what my brother is thinking now......"

Wu Nai said: "If the old fox lied to us, it means that he is just bluffing, then many of the things and words he said later may just scare us." But if he didn't lie to us, we'd really have to be careful. ”

Wu patiently thought: After all, Lu Yunhe's murderous appearance just now was very terrifying, if he didn't act for himself, then once he really started to do it, he would definitely not stay. The Liu family, the Bai family and themselves are afraid that they will be completely erased from this world.

So now it's time to get to the bottom and think about what to do next.

Bai Yu sighed and said, "Okay...... So brother, what do I need to do?"

Wu Nai pointed to the crack in the wall at the secret door, and said: "Xiaobai, you stand next to the secret door, if you really accidentally touch the mechanism, you can hold the door for a while, and we can escape." ”

"Understood. With that, Bai Yu stood on the threshold and pressed his seven-foot-long sword steel whirlwind against the crack of the wall of the secret door like a door bolt.

"Okay, Xiaobai, wait a minute, I'll take a look first. Wu Nai leaned his face against the stone seat and looked carefully at the bottom of the Qiankun gold box.

Wu Nai found that under the box, there was indeed a thin slit, but what the bottom was, it was really unclear.

Wu patiently thought that if it was just the same weight and the position changed, maybe there would be no problem.

But there is also a risk, if you don't grasp it well, if you really trigger the mechanism, you and Bai Yuke will have to feed the fish.

Wu Nai took a deep breath, and then said to Bai Yu: "Xiaobai, if the situation is not good, you can't go first." ”

Bai Yu returned: "Brother, Bai Yu is not a person who is greedy for life and afraid of death, don't worry, I will definitely resist this door." ”

"Good brother. Wu Nai smiled, then slowly spread his hands and touched the box little by little.

Bai Yu's eyes stared at Wu Nai's hand that was gradually approaching the box, and he watched nervously, still imagining in his heart. If the mechanism is triggered, will they be immediately submerged by the flood before they can react, and turn into two water ghosts in this earthly darkness.

Wu Nai's two index fingers touched the box lightly first, he stopped immediately, Bai Yu couldn't take his eyes off it, he was afraid that Wu Nai would touch the mechanism in the next moment, if he didn't put the door on the top, the two would lose the chance to escape.

It turned out that Wu Nai was just cautiously testing to see how sensitive this mechanism was, and so far, there was no problem.

So Wu Nai took another deep breath and began to try to stick it slowly with his fingers, but he was still too nervous and let the box move.

Bai Yu was startled, and hurriedly pressed his sword against the crack in the wall, but Wu Nai was so nervous that he clenched his teeth, and he didn't dare to let go of his hand, let alone use force.

There was a grinding sound under the box, and the two of them didn't dare to move, carefully watching if the noise would cause any changes.

They waited for a while, but nothing seemed to happen, so the two of them breathed a sigh of relief.

After a pause, Wu Nai took another breath and began to slowly push the box.

Wu Nai carefully pushed the box, and read in pieces: "A little bit is good...... Obedient...... A little bit is good......"

Bai Yu didn't dare to make a sound, for fear of distracting even Wu Nai from paying even a little attention, so he could only stare at the box with his eyes wide open.

"That's enough!

When Bai Yu heard Wu Nai's words, he finally let go of the stone in his heart.

Wu Nai pressed his face against the stone seat again and looked at the gap under the box.

Bai Yu saw that Wu Nai stared at Wu Nai for a long time and didn't speak, so he asked a little anxiously: "Brother...... Did you see anything?"

Wu Nai returned: "Xiaobai, that old fox really didn't lie to us...... Under this box, there is indeed a wooden mat. The box seemed to be placed on a stone platform, but it was actually the wooden mat underneath that carried its weight. ”

Wu Nai raised his head and continued: "No wonder we obviously touched the stone seat just now, but the mechanism didn't react. If the weight on the wooden mat does not change, then just touching the stone platform will not affect the mechanism. ”

Bai Yu still carefully pressed the sword against the crack in the wall, and asked, "Then brother, you just said that if the prime minister didn't lie to us, it means that if we dare to leak the secrets here, he will definitely not let us go?"

"Well, so to speak. ”

Wu Nai patted Bai Yu on the shoulder, meaning that he didn't have to worry about the mechanism anymore, and then said to himself suspiciously: "Strange, since the secret thing here is true, and the tone is very important, so important that he can do whatever it takes to ruthlessly wipe out all the people who know the secret." Tut...... So why did he let us go?"

Wu Nai really couldn't figure it out, he knew in his heart that such a thing as competing with foreign envoys was not a major national event for Lu Yunhe.

To put it simply, he is dispensable to Lu Yunhe, and if he really wants to do himself, it is nothing more than to make His Majesty the Emperor unhappy.

Lu Yunhe is a veteran of the Three Dynasties, and he is high and powerful, the emperor not only admires him very much, he is also the emperor's mentor, even if he goes against the emperor's wishes, it will not hurt him.

So, what is this old fox for?

Wu Nai really couldn't figure it out.

Bai Yu on the side didn't disturb his brother-in-law's thoughts, he waited on the side without saying a word.

Wu Nai thought for a while, but still couldn't figure it out, so he could only shake his head helplessly, and said to Bai Yu: "Forget it, one step at a time." Xiaobai, let's go up!"

Bai Yu nodded, so the two of them walked back to the Shangwu Hall along the tunnel.

The two of them listened to the sound in front of the secret door on the upper floor, confirmed that there was really no one in the Shangwu Palace, and then found the mechanism to open the secret door on the upper floor, and walked all the way to the inner courtyard of the Shangwu Palace.

The dark clouds outside have completely dispersed at this moment, and seeing the moonlight of reunion after a long absence, Wu Nai feels as if he has come back to life.

Bai Yu asked at this moment: "Brother, now that you are out, there is no movement outside, should we go back to the other courtyard directly?"

Wu Nai said to Bai Yu: "Xiaobai, take off your clothes!"

"Oh," Bai Yu was about to unbutton when he suddenly asked, "Ah, brother, why do you want a wide coat?"

Wu Nai unbuttoned himself and said, "Xiaobai! Our night clothes are double-sided!

Only then did Bai Yu react: "Oops! So many things happened tonight! I forgot about this stubble!"

The two turned their clothes and pants over, and then put them back on, all dressed in black, and instantly turned into two different sets of clothes, one white and one blue.

Wu Nai smiled, pointed to his white clothes and teased: "Xiaobai, I think the white set should be worn by you." ”

Bai Yu returned seriously: "Brother, although my surname is Bai, people with the surname Bai don't necessarily have to wear white clothes." If a person's surname is Lei, then wouldn't he have to be hacked by Lei every day?"

Wu Nai smiled: "Xiaobai, I think that even if you don't rely on the sword to eat in the future, and go to the overpass to talk about cross talk, you will definitely not starve to death......"

"Huh?" Bai Yu couldn't hear clearly.

"It's nothing, let's go back, I'll explore the way first. After that, Wu Nai pushed open the courtyard door of the Shangwu Palace, stretched out his head to probe, and found that there was indeed no one around, and Lu Yunhe really withdrew everyone.

"No one, go!"

Wu Nai swaggered on the right road, Bai Yu was a little uneasy, and asked, "Brother, let's be careful, right?"

Wu Nai returned: "Don't worry! The old fox will definitely evacuate everyone, let's just leave with peace of mind." ”

Wu Nai had just finished speaking, only to hear an angry roar from behind: "What person!
