The night was hazy, and the two of them sneaked all the way to the near wooden building. Xiao Tianchi turned into a black afterimage and entered the investigation first, while Lin Dong was waiting outside.

In less than a quarter of an hour, Xiao Tianchi returned.

"There are two floors of the wooden building. The first floor is a guard, and the second floor is a servant. There are two guards in the yard to be responsible for the night watch. I estimate that there are about thirty in total." Xiao Tianchi said happily.

Lin Dong was also happy. No matter where he was, the guard's status was higher than that of a servant. In the Han Dynasty, people with high status lived on the upper floors. This wooden building was the opposite, and ordinary people might not think much about it, but in the eyes of those who are interested, it was absolutely strange.

"Zheng Master Xiao, can you avoid the two vigilants at my speed without any silence?" Lin Dong asked.

"The two of them are taking a nap. As long as you don't make too loud noises, it's okay to walk in with a swagger." Xiao Tianchi laughed.

"Okay, let's go in."

Xiao Tianchi took the lead, Lin Dong followed closely. After Xiao Tianchi turned over and entered the yard and confirmed that there was no abnormality, Lin Dong jumped in.

In the yard, two guards were nestled in the corner of the wall, holding their hands with their chests, and napping against the wall. The appearance of the two did not arouse any warning to them.

He quickly flashed into the unclosed lobby. The two of them avoided the sleeping guards from left to right, searched the room one by one, inserted the spiritual sword into the crack of the door, and quietly moved the bolt of the third door of the left hand. Xiao Tianchi slowly pushed open the door.

This is a utility room, shovels, shovels and other farm tools are piled up all over the ground. After finding a bamboo bed in the corner, the two of them were surprised and moved slightly.

A simple utility room filled with ordinary farm tools, and people even need to watch the night. Unless there is any special reason, it is impossible.

With spiritual power pouring into his eyes, Lin Dong looked up at the middle-aged man lying on the bamboo bed and fell asleep soundly. He studied it carefully and his eyes were frozen on his face.

His skin is slightly white, and although there are some wrinkles on the forehead and the corners of his eyes, it is not obvious. He doesn't look like an elderly mate. Moreover, his breathing is stable and gentle, so he is very likely to be a trainee.

Xiao Tianchi obviously noticed this, closed the door, looked at Lin Dong, and whispered: "Mengyan only has five people. Should I be confused first or later?"

Lin Dong whispered: "I am so confused that the agency is in this room very likely. There is only one person anyway, so much is not wasted. If the agency accidentally wakes him up, things will be troublesome."

Xiao Tianchi nodded, took out a small porcelain bottle, and gently tapped the ground with his toes. His thin body seemed to be moving with the wind, floating next to the bamboo bed.

Unplugged the bottle plug, a wisp of blue smoke overflowed from the bottle. The moment the middle-aged man inhaleted, Xiao Tianchi quickly put the bottle under his nostril.

After a few breaths, Xiao Tianchi put away the small porcelain bottle. Looking at the middle-aged man, his breathing was still steady and gentle, but at this moment, even if the thunder exploded in his ears, there was no possibility of waking him up.

This dream smoke has the same effect as the worldly fragrance. The difference is that the medicine of dream smoke is not only more powerful, but also has no odor. There will be no side effects such as headaches after waking up. If you can put thousands or eight hundred bottles in a room, the strong may not be able to escape smoothly after discovering the abnormality after entering.

Xiao Tianchi began to search everywhere. Although there was a secret passage in the utility room of Linji Inn, Lin Dong had no idea about the secret passage of the agency, which could not help but touch the agency. The sound of the agency opening was too loud, so he could only stand aside and wait.

Xiao Tianchi did not miss any details, searching inch by piece, from left to right, when he found the bamboo bed, he squatted down with his hands and kept groping along the legs of the bed.

Almost touching every position of the bamboo bed, Xiao Tianchi stood up, leaned over and grabbed the edges of the bamboo bed, and used a little force to grab the people and the bed.

Lin Dong glanced over and there was a ring-sized ring under the left foot of the head of the bed, which made him unable to help but exclaim.

Looking at the ring, Xiao Tianchi breathed a long sigh: "It should be here!"

Lin Dong hurried forward. The ring was made of copper, and the location below seemed to be connected to the ground, not here.

After moving the bamboo bed away, Xiao Tianchi did not immediately deal with the ring, but continued to search.

After waiting patiently for nearly an hour, Xiao Tianchi searched the entire room in a slight manner, his eyes closed slightly, and pondered for a long time in Lin Dong's face of expectation, and a smile appeared on his thin and black face.

"There should be no problem with the secret passage. I have already recorded the location of the room and I can go down."

Lin Dong couldn't help but breathe a sigh of relief. He could wait patiently for so long, but he was worried that he would pull up the metal ring. With the rumbling sound, an authentic tunnel appeared somewhere in the room, and suddenly burst out dense crossbow arrows from all directions.

Unexpectedly, Xiao Tianchi was so careful that he also recorded the items in the entire room.

Xiao Tianchi strode forward, his index finger inserted into the metal ring, and pulled it up slightly.

At the left wall of the two, a low roar sounded, and a small half of the wooden wall about six or seven centimeters thick slowly opened inward, pushing many wooden barrels piled on the ground aside.

Behind the wooden wall, a small dark room about two square meters is exposed. Below the small room is a wooden ladder that stretches down.

Xiao Tianchi took the lead, and the two of them continued to go down the wooden ladder, and the narrow passage opening continued to expand as they penetrated.

"It seems that this passage is originally a downward cave. Could it be that... the spirit tree grows underground?" Xiao Tianchi frowned slightly. In addition to absorbing the spirit energy of heaven, the spirit tree mostly needs sunlight like ordinary trees. If it is underground, it is not impossible, but the probability is much smaller.

Lin Dong was just the opposite. He remembered that Old Man Ding once said that the blue tree likes loneliness and cannot even tolerate another tree trunk, let alone other trees. If it is underground, it can explain why no blue tree was found in the entire plantation before.

Xiao Tianchi stopped and stopped all the way, and almost every ten meters, he had to study whether there was any mechanism. He slowly walked down the slope for about a thousand meters. Not only did the cave expand to a diameter of less than ten meters, but even the soil under his feet slowly changed from yellow to dark brown, and the air seemed to be filled with a faint smell of decay.

"Spiritual tree, this spirit tree is actually in the cave."

Suddenly, Xiao Tianchi exclaimed.

Lin Dong calmed down and saw that his gaze barely increased from six or seven meters to more than ten meters, but it was still pitch black in front.

It was another twenty meters tall, and a short tree about two meters tall finally entered Lin Dong's sight. Behind the short tree was a cave wall, which obviously had reached the end of the cave.

Going further forward, the decayed smell in the air gradually fades, and the faint fragrance comes to your face.

"It's the spirit tree, it's this spirit tree!" Xiao Tianchi's voice trembled slightly.

Lin Dong frowned slightly. It took more than a month to collect information and ponder the Yang family's industries one by one. As expected, this kind of plantation is indeed the location of the Blue Tree. But the cave has reached its end, where is the other trunk of the Blue Tree?
