The first stick of incense was lit.

The "click" sound of pulling the Nine Palace Lock also sounded. Some people were not hurrying and slow, while others were a little impatient and completely disorganized.

Fu Wenqian's posture was calm, and her slender jade fingers were moving slowly. Before everyone could clear their thoughts, they heard a crisp sound, and she had opened the Nine Palace Lock.

Everyone couldn't help but cast their gazes at her, their eyes unable to conceal their amazement.

The corners of Fu Wenqian's lips curled up slightly, with a proud look on her face.

She cast a contemptuous glance at Lan Qingjia, then looked at Ke Yang proudly, her voice clear and sweet, "I have unlocked the Nine Palace Lock."

Ke Yang smiled faintly, "The condition for breaking through is to take out the key from the box. Miss, you might as well take a closer look into the box."

Fu Wenqian frowned. She looked into the box and paused slightly.

It turns out that there is another box inside the box, and the lock on that box is still the Jiugong lock.

She got carried away too early, and Fu Wenqian's expression became a little stiff.

She paused, and soon regained her proud and confident posture, "It's just one more Nine Palace Lock, so what's the difficulty?"

On the other end, there was a "click" sound, and Lan Qingjia unlocked the first Nine Palace Lock.

Without even raising her head, she started to unlock the second lock.

If her guess was correct, there must be layers and layers of boxes hidden in this box, and the further to the back, the harder it would be to unlock the Nine Palace Lock.

The time it takes to burn two sticks of incense seems to be a long time, but it is not.

This is the riverside, and the wind is very strong. The time for burning two sticks of incense will be greatly shortened. What's more, who knows how many boxes there are in this box?

Fu Wenqian's eyes flashed slightly, and she didn't waste any more time and began to continue immersed in it.

"Click"

There was another crisp sound, and Lan Qingjia unlocked another Nine Palace Lock.

As she expected, there was a smaller box hidden inside this box.

Lan Qingjia was aroused to be competitive, and her face showed an eagerness to try.

Her brain seemed to have been opened up to Ren and Du's two meridians, her mind was clear and her hands were moving faster and faster.

Everything about her is in her head.

Fu Wenqian was already confident, but she got stuck when she solved the third Nine Palace Lock. The difficulty of this Nine Palace Lock was beyond her imagination.

But Lan Qingjia's movements were still smooth and fast, and the rhythm of unlocking was even faster than before. The "click" and "click" sounds were very rhythmic, like a magic spell.

, which made her uneasy, and the Jiugong Lock in her hand became more and more chaotic.

Mu Jihe was also stuck in the third level. He repeatedly made failed attempts, and his attention was always drawn uncontrollably by Lan Qingjia. The sound of the nine palace locks colliding became more and more impatient.

Lan Qingjia had no idea how much interference she had caused to others. Her attention was only focused on her own Nine Palace Lock.

The third Nine Palace Lock is unlocked.

The fourth Nine Palace Lock is unlocked.

By the fifth level of the Nine Palace Lock, the lock body was already very small and could even be called pocket-sized. She could only operate it with a hairpin.

This should be the last one.

Before she knew it, the first incense had burned out, and most of the second incense had burned out. She didn't have much time left.

The further you go to unlock the Nine Palace Lock, the more difficult it becomes. When it comes to the last one, Lan Qingjia also feels the slightest pressure.

If you can't clear the level, there is no difference between unlocking one and starting four.

Success is right in front of her, and she can't lose.

She calmed down, organized her thoughts, and slowly explored and tested bit by bit.

As time passed by, the stick of incense was only as high as a fingertip. The shorter and shorter height was like an invisible pressure, pressing down on everyone's hearts little by little.

Fu Wenqian was still stuck on the third Nine Palace Lock. Her normally arrogant and self-sufficient face had already shown an ugly look. Her entire face was tense and there were waves of low pressure lingering around her body.

With a "click" sound, the sound announcing the successful unlocking sounded again.

Lan Qingjia breathed a long sigh of relief. She quickly opened the wooden box and took out the small key hidden inside.

The small key was spread out in her white palm, making people feel extremely jealous when they saw it.

A gust of river wind blew by, the last incense ashes were blown away, the two sticks of incense were burned out, and the time was up.

Ke Yang looked at her with a smile and said in a respectful tone, "Congratulations, Miss, you passed the fourth level."

Lan Qingjia breathed a sigh of relief, and a smile appeared on her face.

In that smile, her beautiful face and dimples were shining brightly, as if all the excitement of early spring had been driven away.

Mu Jihe couldn't help but turn his head to look at her, and when he saw her smile, he felt as if he had seen her before.

Everyone's eyes unconsciously turned back and forth between Lan Qingjia and Fu Wenqian, their expressions unpredictable for a moment.

Compared with Lan Qingjia's dimple-like smile, Fu Wenqian's whole face was tense, with a mixture of blue and white, which was very wonderful.

Lan Qingwan's face was also very ugly. She felt unbelievable and filled with jealousy. How could this be possible? How could she unlock the Nine Palace Lock? How could she win?

For a moment, her teeth clenched.

Lan Qingjia looked at Fu Wenqian with a faint smile, and smiled sweetly.

"Miss Fu, I won this bet and accepted it."

Fu Wenqian's face was stiff, and when she saw her smile, she felt it was extremely dazzling, and a feeling of depression accumulated in her chest, which lingered, and her face was even hotter, and she was extremely embarrassed.

She has never experienced such an embarrassing defeat in her life!

Fu Wenqian stood up angrily and walked away without saying a word..zx.

The other ladies hesitated for a moment, and then hurriedly followed up. Even if Fu Wenqian lost, she was still the daughter of the prime minister, and she was the one they needed to continue to be friends with.

Lan Qingwan secretly regretted that she provoked the bet between the two. According to Fu Wenqian's character, she must secretly hate herself in her heart. She had spent so much energy to please her, but now she has failed!

She gave Lan Qingjia a hard look and quickly chased after him.

Mu Jihe looked deeply at Lan Qingjia, with flashes of light in his eyes.

However, Lan Qingjia didn't pay him any attention. She turned around and got into the snake chariot with Ke Yang.

After getting into the snake chariot orchid, I realized that it was very spacious and could accommodate more than twenty or thirty people.

She observed the snake chariot calmly, and saw that the brackets in the chariot were all made of fine iron coated with tung oil. There was a thick iron pillar extending from the deep water to the waterfall. It seemed that the upper and lower parts of the snake chariot were all connected with each other.

This has something to do with the iron pillar.

Lan Qingjia searched in her mind the lectures she had heard from Mu Jihe in her previous life, and slowly clarified the principles of this magical snake chariot.

The gears, cranks and connecting rods are all exquisitely designed and interconnected to ensure the stability of the telescopic frame, and its lifting and lowering cleverly utilizes the hydraulic braking transmission device.

Every aspect of this design is exquisite and amazing.
