Step Nine and Step Ten glanced at each other, and Step Ten nodded.

Bu Jiu walked outside and whistled in the air, and heard an eagle sound from far and near in the air. With the sound of the eagle, a large, vigorous eagle landed in the courtyard.

Li Ziyu and the others were all shocked and came to the courtyard one after another.

Through the faint light of the hall, Li Ziyu found that this eagle had wide wings, a thick body, and a cyan body, without a trace of miscellaneous hair. Li Ziyu knew that this kind of carving was called a green carving. At first she thought it was black, but when she looked closer, it was cyan.

This kind of green eagle grows in the northeast region, often inhabits swamps, rivers, watersides and other places, and eats lizards, frogs, small birds, gulls, crows and rodents, and also often eats animal carcasses. The green eagle has a keen eyesight, a fierce temperament, and a fast and persistent flight.

They do not have a single way of catching food, sometimes they wait on cliffs and tall trees, wait for their prey to appear, and then swoop down to eat; sometimes hovering high in search of prey; sometimes they rise up from the ground and pounce on food at low altitudes; There are also times when they flap their wings quickly and agilely, and follow the prey in pursuit.

This kind of bird of prey was actually trained as a messenger, and Li Ziyu couldn't help but have a new understanding of Ren Xiaohang.

At this time, Bu Shi had already written the letter in the house, stuffed it into a small bamboo tube, and tied it to the green eagle's leg.

They had been delayed for so long in Shiyan Town, but they had not found any useful clues. This time, Li Ziyu found the cave crookedly, no matter whether the cave was suspicious or not, he should tell the owner to know.

Although they haven't figured out the details yet, they can't let go of any clues.

Li Ziyu plucked a hare from the wall. threw it to the green eagle, and scooped half a basin of water from the water tank and put it on the ground.

After a while, the green eagle tore the hare and swallowed it in its stomach, and sucked up half of the basin of water. Circled around the yard, then spread its wings and flew into the air, disappearing in an instant.

Everyone watched the green eagle go away, and then returned to the house to eat.

At this time, it was close to midnight, and everyone was already very tired because of Li Ziyu's trouble. After a hasty meal, they rested.

While sleeping. Xiaolan insisted on sharing a quilt with Li Ziyu, she made Li Ziyu frightened, and it seemed that she could only hold her sister. My sister won't disappear.

Li Ziyu saw Xiaolan clinging to herself like this, and her heart was soft. She hugged her sister's soft little body tightly, making her clinging to her tighter, and the sisters hugged each other and fell asleep together.

The next day, everyone got up early and exercised in the morning as usual. It's just that everyone has increased the difficulty during the morning exercise today. That desperate posture even Li Ziyu was a little surprised.

Especially Xiao Wu, he insisted on tying the same amount of sandbags on his legs as Xiaoshan and Xiaowen, and no one could say anything.

And the atmosphere of today's morning exercise was a little depressing, no one spoke, and there was a solemn expression on their faces.

After morning exercise and breakfast, Xiaoshan still took his younger siblings to practice and read.

Today it was the turn of Bu Shi to be on guard on the locust tree in front of the door, and Bu Jiu was idle.

Because tomorrow is the thirtieth day of the lunar month, Li Ziyu plans to take a look at the meat at home. If you need to take the water to blister, soak it quickly, or it will be too late to soak tomorrow. Because all the meat in the house is hung on the wall outside. It's so cold that you can't soak it at all without soaking it in advance.

The mushrooms that Li Ziyu picked from the bamboo forest yesterday, because there was a full basket, Li Ziyu divided it into several parts, and after the morning exercise, Xiaoshan and Xiaowen respectively sent some samples to the old village chief's family, Aunt Yang's family, and He Shigui's family. This season, everyone is very happy to be able to eat such fresh mushrooms.

Li Ziyu asked Li Luo and Xiao Ou to pick the mushrooms in the air, and they will have to eat tomorrow's Chinese New Year's Eve. Xiao Ou had nothing to do, quietly picking mushrooms on the side.

The strange thing is that where Li Ziyu walked today, where did Bu Jiu follow. That's not all, he looked at her with extremely sad eyes, making her seem to feel that she didn't owe him a lot of money when she didn't pay it back.

Li Ziyu ignored him, and took care of herself and Li Luo soaked all kinds of meat that needed to be eaten tomorrow. When Li Luo entered the west room, Bu Jiu approached Li Ziyu and whispered, "Miss Li!" ”

Li Ziyu glanced at him strangely and asked, "Brother Bu, is there something wrong?" ”

Bu Jiu's eyes flashed with a blazing light, and he pointed outward.

Li Ziyu looked outside, there was nothing strange. Turning his head to look at Bu Jiu, what does it mean?

Bu Jiu whispered: "Miss Li, let's go to the cave to explore, let's see what is the place outside the cave you said." ”

"Wouldn't it be possible to go another day? Tomorrow is the New Year. Li Ziyu hesitated for a moment and said.

"Oh, isn't that tomorrow? Aren't you okay now? Go for it, don't you wonder what the hell is there? Bu Jiu continued to lobby.

To be honest, Li Ziyu is really curious. It was late last night, and I couldn't see what was there. Why don't you check it out?

Li Ziyu looked at the hour, that is, at the beginning of the hour, and the modern hour is more than nine o'clock in the morning. If you go back quickly, you should be able to come back by lunchtime.

But they can't let Xiaoshan know, and if they do, they will definitely not let her go again. So she whispered to Li Luo, but she didn't say where to go. said that she and Bu Jiu went out for a trip, had something to do, and promised to come back before lunch.

Li Luo thought that they really had something to do, so she didn't ask in detail, so she didn't say anything.

Li Ziyu and Bu Jiu walked out of the courtyard gate, Bu Jiu gestured to Bu Shi on the tree, and came to the back mountain with Li Ziyu.

The two of them glanced around vigilantly, and Bu Jiu pricked up his ears and listened quietly for a while, until he confirmed that it was indeed safe, and then nodded to Li Ziyu.

Li Ziyu came to the dead tree, jumped into the tree hole, groped to find the switch, and pressed it lightly, the bluestone slab below moved silently to the side, and the hole appeared in front of him.

Li Ziyu and Bu Jiu entered the cave one after another, and went down the wooden ladder to the cave.

Li Ziyu found the switch, pressed it gently, and the bluestone slab on his head closed silently. And there was a "click" sound at the switch, which startled Li Ziyu. There wasn't that noise last night, what's going on?

Li Ziyu pressed the switch again, and the bluestone slab on his head opened silently again. Press it again, and there was another sound, and the bluestone slab was closed.

Li Ziyu frowned and thought about it, she let Bu Jiu go out first, and see what changes had happened outside after she closed the door of the cave.

Through trial and error, Li Ziyu found that if you enter the cave and close the door, you will never be able to open it from the outside, even if there is a switch. Going out can only be opened from the inside. The outside switch is just the one that can enter the cave. That is, after they enter the inside, they can control the switch from the inside to prevent people from the outside from coming in.

The two of them figured it out, and without further delay, they hurried to the cave. When they came to the switch at the fork in the road, Li Ziyu and Bu Jiu conducted many more tests. I found that the setting of this switch is the same as the setting in the tree hole, and the switch on the outside can control the inside. The switch inside can just open the door.

I don't know who designed the switch of this cave, plus the transformation of the entire cave, ordinary people really can't design it.

Li Ziyu took Bu Jiu along the cave last night and walked towards the end of the cave, and they didn't know what was waiting for them. But they've come in anyway, so they're sure to find out. (To be continued......)
