Hearing this, Ronan was stunned, and finally understood the most critical issue. He looked around at the treehouse, was silent for a few seconds, and finally decided, "Let's go back first." ”

After looking at the projection album in his hand, he hesitated for a while, but put it back in place so as not to damage the original layout of the treehouse, and then closed the bionic bark on the viewing window to make sure that no one would find it.

After all this was done, Ronan's eyes turned to Xie Junping, who immediately raised his hand and swore, "I will never mention the treehouse to outsiders, this matter will rot in my stomach." ”

Ronan didn't say a word, just bowed again. Since the last solemn thank-you, Ronan has shown a more respectful attitude towards Xie Junping, and frankly speaking, this is quite refreshing in Xie Junping's heart.

The disposal here has been completed, Ronan should go down first, Xie Junping followed behind, perhaps because he was in a good mood, but Xie Junping had an idea in his mind inexplicably, and with the courage to improve, he stabbed Ronan in the shoulder:

"Brother Nan, if you don't mind...... Can I keep a camera? ”

"Huh?" Ronan turned his head abruptly, staring at his face.

People's mentality is so strange, in the past, Xie Junping must have been nervous, and he might not even be able to say a word. But after feeling Ronan's respect, his courage also increased accordingly, and under Ronan's gaze, his thinking became clearer:

"I mean, Brother Nan, don't you think this house is too clean? There are many mosquitoes in the wetland, and the humidity is heavy, and if you don't take care of it for a few days, you can't see it. But look here, it's clean, it's refreshing, it's good-looking, but I'm afraid ......."

Ronan didn't blink his eyes, his voice was dumb, and he said Xie Junping's unfulfilled meaning: "Someone has already discovered this place and lived here for a long time?" ”

"Ahem, that's what I said. After all, eighty percent of the intelligent cleaning system in the 'gears' can't come here. ”

Ronan didn't say anything more, but his eyes drifted a little, not knowing what he was thinking. After a few seconds, he turned around and walked slowly, keeping his fingers on the inner wall of the tree hole, until he reached the beginning of the wood-grained stone steps, and suddenly said:

"Here, there used to be a door, but now it's filled with biomimetic materials and sealed."

Xie Junping put the lighting on it, observed it, and agreed: "Maybe it's the normal portal that was set aside when the sandbar was still there." Later, when the water level rose, it was scrapped. ”

"The water level is rising ......"

Ronan's voice became more and more hoarse, as if there was a blade in his throat, and he spoke more and more difficult: "When did the water level rise?" ”

Xie Junping checked the information on the Internet: "It's about 87 years. At that time, the underground rock layer was fractured, and an underground river was diverted, which raised the average water level of the wetland by nearly half a metre, and the lake area, where the dead tree sandbar is located, rose by a full 1.7 metres. Uh, '87......"

It seems that Sister Bu Qingwen died of dystocia, that is, 80 years, and it is impossible to renovate the tree hole space after seven years anyway.

Once the train of thought was straightened out, Xie Junping sizzled:

"What a man!"

"Yes, there are real people...... Who is it? Ronan responded in a hoarse voice, and slowly leaned down, touching the narrow passage that was obviously dug in the later stages.

Xie Junping also woke up, and this Yongdao, ninety percent of the nine was also excavated during the same period when the gate was closed, also to avoid the rising water level, so as to facilitate entry and exit.

In this way, the difference with Bu Qingwen's original design can be explained.

Xie Junping saw Ronan bending over, as if he was pondering the structure of the secret passage, so he turned on the lighting beam to facilitate his investigation. But when the beam hit, I realized that something was wrong.

At this time, Ronan was indeed thinking, but his fingers were unconsciously moving at the junction of the tree hole and the secret passage, and the monotonous movement was not so much inertia as a representation of some extreme emotion.

Before, Ronan was heavy and sad, but relatively calm, and the occasional ups and downs were like night tides on the seaside, which was the rhythm of normal emotions.

However, at this moment, he was depressed and manic, like a wounded beast, full of manic depression and even murderous emotions when he saw the enemy who hurt him break into his territory.

Xie Junping was really worried that Ronan would pick off his nails, so he carefully shook the lighting beam.

The change in light surprised Ronan, and Huo Ran turned around.

Xie Junping suddenly saw that Ronan's eyes were blood-red at this time, not soaked in tears, but the accumulation of violent emotions, and he wanted to choose someone to eat!

Seeing this situation, Xie Junping only felt that his legs and stomach were spinning, and he unconsciously took a step back.

However, under the light, Ronan's mood seemed to calm down, and he stopped his creepy monotonous movements and whispered:

"Senior, where did we just go?"

"Well, someone lives in a tree hollow, seals the front door, and digs a secret passage to the lab."

Ronan shook his head: "The underwater promenade is a dead end, and it is usually unobstructed. It's too dazzling for outsiders to come in. So, it won't be anything else, it can only be an insider of a club or a laboratory. ”

Xie Junping is right to think about it, this is more reasonable.

If you think about it a little deeper, there is such a person in the Order Club, who usually lives and socializes normally in the club, and when others are not paying attention, he will quietly walk through the underwater corridor and enter the tree hole, and engage in some kind of shady deed. The most important thing is this time span, which may even last for seven or eight years, more than ten years, until now...... It's chilling to think about.

Xie Junping suddenly had a thought: Sister, when they are drilling the secret passage, someone suddenly comes in from the other side!

Or you can also swim in the water and drill in through the viewing port......

As soon as he thought about it, he looked at the secret passage of the black hole and the stairs spiraling up behind him, and the whole person was not good.

Ronan didn't seem to think so much, he slowly stood up and owed to Xie Junping: "The matter of the camera will trouble the senior...... If there is someone, if there is still someone, I want to see, who he really is! ”

Xie Junping was actually a little panicked in his heart, but with Ronan beside him, it was somewhat comforting, and he took a deep breath: "Okay, I'll pretend now!" ”

“…… Have ready-made tools? ”

"Well, with a little bit."

Xie Junping was a little embarrassed, but he still took out two miniature cameras the size of a grain of rice from the bracelet strap. They are the rich second generation, and sometimes they play some ridiculous flower work, and that's all they rely on.

This kind of portable micro-machine is the easiest to install, find a position with a wide viewing angle, press it and stick it, and it is easy to fall off.

Xie Junping used both cameras: "This gadget can achieve real-time image transmission, and one camera can work for more than 3 months." In fact, depending on this level of cleanliness, if you are smart, you can get results in a day or two. ”

During Xie Junping's work, Ronan walked up and down the entire tree hole space, but found no more clues. At this time, his mood was obviously more depressed, and without saying a word, he first went through the secret passage and entered the underwater corridor.

Xie Junping cautiously followed, turning on the surveillance screen at all times, for fear that a murderer who had been hiding for many years would suddenly jump out of his back!
