She married a dying prince and she won three babies.

"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 of the cave on both sides to prevent any hidden weapons or mechanisms.

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

In the end, we only walked a dozen feet to the bottom.

"Princess, it's the same mechanism we destroyed just now." Chunlei 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 is the one that operates this iron rack.

He took hold of the handle and turned it.

If there is no response, try another direction.

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, it is three feet high.

Spring thunder and summer rain go 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 go.

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 it 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.

There are tunnels in the yards of both mother and son, and they are connected.

What does it mean?

A bold guess came to my mind.

"Come on, let's go down and walk around a bit to see where the tunnels lead to."

She wanted to prove her guess again.

Several people returned to the tunnel.

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 distance walked was much longer than before, about fifty feet.

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

After walking about two hundred and fifty steps in total, we reached the end.

But there is also a lot of soil filled here, which is obviously loose.

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

Zhuyue, who was behind, went back the same way and got three dustpans filled with soil.

Several people worked together to dig up all the soil and spread it in the tunnel, 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 sure enough, the stone slab on top slowly rose, and with another push, it moved to the side. A hole appeared.

Then they heard the 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 voice of the wet nurse.

"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 is wrong with 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 restored the hole.

Now everyone knows that this tunnel leads 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 to explore.

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

Keep going.

This time we went even further.

When they finally reached the end, it was the same iron frame.

When we got up, we found a small courtyard, but no one lived there.

It doesn't look like a deserted yard.

But 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 his post."

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

After hearing his words, Yu Yuanzheng looked up to the sky and let out a long sigh.

It couldn't be clearer.

She would never have imagined this outcome, and she didn't know how sad her father would be if he knew.

I wonder how sad my husband would be if he knew.

The biggest spy had actually been in the palace all along.

She recalled what Fang Guilin, the pharmacist whom she and her husband met in Jingkai City, had said about the Canglan royal family.

The current Emperor Canglan once had a sister who blocked poison for the late emperor and died. Then, she and her mother benefited and were given the position of virtuous concubine. It was because of the death of such a daughter that the current Emperor Canglan won the favor of the late emperor and eventually ascended to the throne.

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

When her child-swapping affair was exposed, she deliberately intensified the conflict and made the prince furious. In the name of atonement, she hanged herself on the same day as Luo.

joke.

Yu Yuanzheng was 100% sure that she was definitely not dead, but had faked her death to escape.

The one who died must be a substitute.

When the guards saw Yu Yuanzheng's appearance, they all fell silent.

They all thought of it too.

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

But Yu Yuanzheng didn't want to say more now.

"Xia Yu, go to the place where the third wife 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 a tunnel like this?" Yu Yuanzheng asked softly.

"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 sighed deeply.

I admire the strong will of the third wife.

Yu Yuanzheng and the others did not return to the tunnel, but walked through the side door to return to the palace.

This is the back street of the palace, where servants with families live.

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

Seeing that their mother's face was not right, the three children stopped making 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 received today and adding her own 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, which can be confirmed from the fact that he looks 50% like the prince.

But 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 powerful 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 princess of Canglan Kingdom was willing to come to Wei to be a concubine, just to complete 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 for him to become the crown prince.

That's why Shangguan Ziqi fell off his horse and became a vegetable.

They also used the second wife to help them take the lead.

He also placed people in the princess's courtyard 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 Shangguanzi chess game is ready, take the next step and steal the iron box directly.

The assassination on the night she gave 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 steps over and over again, Xia Yu came back.
