"Go over here and take a look." Yu Yuanzheng pointed to the fork in the road.

Chunlei held a long sword in his hand and kept knocking on the walls on both sides of the cave to prevent any hidden weapons or traps.

The six people walked into that fork, which was no different from the one they had just walked through.

It took Jie Yu only about ten feet to reach the bottom.

"Princess Zi, it's the same mechanism we destroyed just now." Chun Lei looked up and saw that the top of the cave was also an iron frame.

"Can it be opened?" Yu Yuanzheng couldn't see because there were two people between them.

"I'll try it first."

Chunlei held up the lantern and saw a rotating handle on the right side of the shelf.

I guess it’s the iron frame that was made.

He took hold of the handle and turned it.

If there is no response, try another method.

Moved.

The floor above slowly rose a little, then pushed forward again.

This mechanism is really cleverly designed.

Then the light came down.

From bottom to top, there are three heights.

Chunlei and Xiayu went up first.

Yu Yuanzheng was able to climb up only after putting a stool down as a cushion.

The others all had martial arts skills and jumped up in one leap.

Butler Li is also a martial artist.

When I came out, I saw that it was a study.

Right under the desk.

There are many books in the room.

Several people walked out of the study.

"This is the third master's courtyard." Butler Li knew where this was at a glance.

Yu Yuanzheng had never been here. Although Third Aunt had invited her to come, she had never found the time.

This is interesting.

They, mother and son, both have plots of land in their yards, and they are connected.

What does this mean?

A bold guess came to my mind.

"Let's go down and walk a little further to see where the ground leads to."

She wanted to prove her guess again.

Several people returned to the ground.

Go back to the fork in the road and continue walking forward. After walking several more feet, another fork in the road appears.

"Go this way." Yu Yuanzheng pointed in a direction based on his feeling.

The walking distance was much longer than before, about fifty feet or so.

Yu Yuanzheng counted her steps in her mind. Given her height and the size of her steps, she could walk two meters in three steps.

After walking about two and a half steps in total, I reached the end.

But there is a lot of soil filled in here, and it looks soft at first glance.

The place is quite narrow, so it is not easy to remove the soil.

Later, Zhuyue went back and got three dustpans filled with soil.

Several people worked together to dig up all the soil and spread it on the ground, a thin layer that did not affect entry and exit.

When the dirt was cleared, they saw the same iron frame.

Chunlei used the same method, and the stone slab on top slowly rose, and then pushed it aside. A hole appeared.

Then they heard a baby crying.

"Mrs. He, what's wrong with the child?" It was Yu Chaoyang's voice.

"Replying to the Second Madam, I don't know what's wrong with the young master. He doesn't want to drink milk." The wet nurse said.

"Let me see." Yu Chaoyang was anxious to see the child.

"Second Madam, please ask the palace doctor to come and take a look. I'm afraid something has happened to the child." The wet nurse was also anxious. She was afraid that the child would be lost.

"Qinghe, hurry up and get the palace doctor."

The spring thunder spun a few more times and filled the hole again.

Now everyone knows that this place is connected to the courtyard of the third old lady, the third master, and Shangguan Zishu.

This couldn't be more obvious.

"Let's go. We haven't reached the exit yet." Yu Yuanzheng suppressed the anger in his heart and continued exploring.

They returned to the fork in the road, with only one fork left.

Keep going forward.

This time we walked even further.

When they finally reached the end, they saw the same iron frame.

When we got up there was a small courtyard with no one living there.

It doesn't look like a deserted yard.

At first glance, it's obvious that no one has lived there for a long time.

Butler Li went out of the yard to see.

"Princess, I remember now that this courtyard was for a family of servants named Mo, the Mo Lin family who followed the Third Master to take up his post."

Butler Li is really dedicated. He even remembers small things like this.

After hearing his words, Yu Yuanzheng let out a long sigh toward the sky.

It couldn't be clearer.

She would never have thought of this ending. She didn't know how sad her father would be if he knew it.

I don’t know how sad my husband would be if he knew.

It turns out that the biggest spy has been working in the palace all along.

She recalled what she and her husband had said to the drug dealer Fang Guilin when they met him in Jingkai City, about the Canglan royal family.

The current Emperor Canglan once had an elder sister who blocked poison for the late emperor and died. Then, she benefited her mother and obtained the title of Consort Xian. It was because of such a daughter who died that the current Emperor Canglan won the favor of the late emperor and eventually ascended to the throne.

Now it seems that the poisoned sister is not dead at all, but has come to Wei, and is the third old lady of the palace.

Her child-swapping affair was exposed, and she deliberately intensified the conflict to make the prince furious. She then hanged herself on the same day as Luo in the name of atonement.

joke.

Yu Yuanzheng could be absolutely sure that she was definitely not dead, but had faked her death and escaped.

The dead man must be a substitute.

When the guards saw Yu Yuanzheng's expression, they all remained silent.

They all thought of it too.

On the contrary, Butler Li couldn't understand it.

Yu Yuanzheng doesn't want to say more now.

"Xia Yu, go to the place where the third room lives now and ask if the third uncle is still at home?" Yu Yuanzheng still didn't give up.

"Yes." Xia Yu ran away.

"Butler Li, how long do you think it will take to dig out a piece of land like this?" Yu Yuanzheng asked quietly.

"If we dig secretly, we have to consider not being discovered. The biggest difficulty is dealing with the excavated soil. We can only do it bit by bit and secretly transport it out of the city. It will take at least ten to twenty years, or even longer." Butler Li thought for a while and replied.

Yu Yuanzheng was stunned and let out a long sigh.

I admire the strong will of the third room.

Yu Yuanzheng and the others did not go back to the ground floor, but walked through the side door to return to the palace.

This is the back street of the palace, a place for servants with families to live.

Back in the main courtyard, Yu Yuanzheng asked the maids to take good care of the children while she wanted to be alone.

The three children, noticing that their mother looked unhappy, stopped making any noise and, accompanied by their maids, played with various toys in their aunt's playroom.

Yu Yuanzheng sat quietly on the chair with his eyes half closed.

After sorting out the information she suddenly got today and adding her guesses, she was able to roughly figure it out.

The third old lady is Canglan's biggest spy in the Wei Dynasty.

The third master should be the old prince's biological son. This can be confirmed from the fact that he looks 50% like the prince.

However, he was taught by the third old lady since he was a child and became her greatest helper.

Therefore, the Third Master is the second most important spy of Canglan Kingdom in the Wei Dynasty.

The key is that the identities of these two spies are too special.

One is the old prince's concubine, and the other is the old prince's biological son.

No one would think that they, mother and son, were spies.

The dignified princess of Canglan Kingdom was willing to come to Wei to be a concubine, just to fulfill Canglan's great cause.

Yu Yuanzheng was terrified when he thought about it carefully.

In order to control the palace, he transferred his own grandson to the prince's name.

Wait until he grows up, and then plan a position for him.

That’s why there was the incident of Shangguan Ziqi falling off his horse and becoming a vegetable.

The second branch of Yuli helped them take the lead.

He also placed people in the princess's harem to control her diet and prevent her from getting pregnant.

He was also afraid that Shangguan Ru's affair would be exposed, so he asked the Lin family to force her to death. This not only stabilized the Luo family, but also prevented her from dying at the hands of the third house.

Knowing that the game of Shangguanziqi is ready, just take the next step and steal the iron box directly.

The assassination on the night of her birth was most likely arranged by them and their son.

I just want them both to die.

This step-by-step calculation is really one link after another.

If she hadn't traveled through time, if she hadn't saved Guan Ziqi, how would things have turned out?

She didn't know.

Just as she was thinking about the various links over and over again, Xia Yu came back.
