"Teacher, what are you doing here?"

The two old professors took Su Junyi, Qiao Xuan and Yin Xiu all the way to the woods behind the college, but they still didn't mean to stop, Yin Xiu couldn't figure out what was worth bringing Su Junyi to this pure back garden in the back mountain woods.

"I don't know." Professor Zhang shook his head.

"Don't know? Don't know if you're still here? Teacher, are you ...... If you really can't do it, retire. Yin Xiu said thoughtlessly.

"You damn girl! Who are you talking about?! Professor Li turned around and kicked Yin Xiu.

In the eyes of these professors, there is no distinction between men and women, especially in the eyes of Professor Li of the mecha department, men and women are no longer the standard for classifying people, in Professor Li's world, people only have the strong and the weak, and they should be merciful to the weak, and they don't have to be polite to the strong.

"Hmm!" Yin Xiu quickly dodged, looking innocent.

Originally, why would they run to the back mountains without any trouble?

"Here we are." Professor Zhang turned around and walked in the direction of a towering tree.

"Huh? Arrived? Where's it going? "Yin Xiu is still the second monk and is confused.

Su Junyi and Qiao Xuan looked at each other and smiled, feeling helpless at Yin Xiu's impatient nature. Since the professors brought them here, there must be a reason, the professors don't say it's probably inconvenient to say, no matter what, they just need to follow, she chatters so much, the professors won't tell them.

"Here, Junyi, you go down."

The tree must have been very old, and its roots had arched out of the ground, entangled with each other. Professor Zhang and Professor Li walked to the root of the tree, and one of them peeled back the vine hanging from the root, revealing a hole tangled by the roots.

This is the place where Su Junyi's father stayed, and he originally planned to bring only Su Junyi here, but when they saw Qiao Xuan and Yin Xiu, who accompanied Su Junyi here, the two professors suddenly changed their minds. Su Junyi, this kid has borne too much by himself, and someone should share some of it for him.

"Thank you, teacher." Su Junyi stared at the dark hole and looked at it, then looked up, looked at the two teachers who had taught him gratefully, stepped forward and gave each of them a hug, and Su Junyi slid neatly into the half-human-high hole.

Qiao Xuan and Yin Xiu were still a little inexplicable, the two glanced at each other, nodded at each other, and then nodded to the two professors, and followed Su Junyi one after the other and slid in.

"Lao Li, let's go." Professor Zhang sighed, turned around and left.

"I don't know what we can do." Professor Li hesitated for a moment before keeping up with Professor Zhang.

"What can we do?" Professor Zhang smiled, "There are some things that only us old men can do. "Their only advantage over young people is status and prestige, and if these are put to good use, they will become the most powerful backing for young people.

"What are you thinking about, old fellow? You can't leave me behind! ”

"I'm still pointing at you as a shield for me."

"A bad stomach!"

The two old professors drifted apart, but Su Junyi and the three of them were blocked in the tree hole.

"Thoughts? What does two teachers mean? Qiao Xuan looked at the solid soil layer in front of him in confusion, and reached out to touch it, it was indeed just the soil layer.

Ideas? It shouldn't be. Su Junyi also felt very confused, walked up to the front boy and carefully groped in the damp soil, thought about it, and began to deduct the soil.

"Junyi, what are you doing?" Qiao Xuan grabbed Su Junyi's hand, "There can't be anything in this soil layer." "Qiao Xuan is also a person who has been to many places and has rich combat experience, whether there is a mechanism behind the soil and rock formations, he can know by touching it.

"Teachers can't just bring us here for no reason, there must be something here." The two teachers had brought them over with such a clear goal, how could it be just to let them experience the dampness under the roots of the tree? There must be a mechanism here, "Senior, look at any of these roots." ”

"Okay." Qiao Xuan looked around at the dirty roots of different thicknesses around him, and although he thought that it was impossible for the mechanism to be here, he still tugged at them one by one.

Even if there is a secret room here, it must have been built many years ago, and these roots cannot always remain the same, whether it is the number or the thickness, they must change, the original ones may be broken, and new roots will grow, it is difficult to use this root to make a mechanism, Qiao Xuan can't think of what kind of genius can make such a mechanism that adapts to change.

However, it turned out that Su Junyi's ingenuity was completely inherited from his father, and when Qiao Xuan pulled a certain root unexpectedly, the earthen wall in front of Su Junyi completely collapsed without warning, and the earth and stones smashed Su Junyi's body.

Su Junyi was stunned with a body of dirt. He has a relationship with the soil recently, and the last time he went back to the villa, he got a gray face, and today it's not good, he's dirt again.

"Uh......" Qiao Xuan still maintained the posture of pulling the roots, and looked at Su Junyi dumbfounded with Yin Xiu.

"Senior, Yin Xiu, you two go back." Su Junyi sighed and patted off the soil and stones on his body.

Father, can you design something normally? However, these unusual designs also show that there is something hidden in it that cannot be found by the world. Although he understands the teachers' desire to find a companion for him, the teacher may not know the seriousness of the matter, and he cannot involve others.

"What do you say?" Qiao Xuan patted Su Junyi the back, "Senior, when will I leave you alone?" Since they all came with you, can they still leave you alone? ”

"That's it! Are we the kind of people who are afraid of things? Yin Xiu wrinkled her nose and said very dissatisfied.

"In the past, I would never refuse your company and help, but now...... You've got families, it's too complicated, and I want you to leave. Su Junyi blocked the entrance of the secret room, looking at his two former partners sincerely.

If he went back to the past, back to the time when they were all children, then he would have been happy to take risks with them, make fools together, and then be punished together, but now it is different, he doesn't dare to mess around with them anymore, he will choose another group of people to fight side by side with him.

"Don't worry, I'm not alone."

"What if you're not alone?" Qiao Xuan glared unhappily, "They are them, we are us!" Anyway, on the planet of Polley, we are the only ones who can fight side by side with you! How is it possible to stand by knowing you're going to get in trouble? ”

"You ...... can stop me from getting into trouble. Su Junyi joked very seriously.
