Su Xiaobai found that he still thought about the situation too well, that T2 did indeed open a passage, yes, it should have directly broken the wall of the ventilation channel, and climbed up with his own claw strength and body strength along the position of the ventilation channel, so this ventilation channel in Su Xiaobai's eyes, every time he reached such a distance, there would be a deep claw mark.

Those claw marks were obviously the focus of the T2's climbing.

But such a difficult movement can only be done by a non-human strength and physique like a mutant, otherwise, it would only depend on the flexibility of ordinary human limbs...... Su Xiaobai didn't dare to think about it.

"How so? What can I do ......? ”

"That's the only way, perhaps, we can borrow that one to climb out." The Superior Detective looked at it, since it was a ventilation channel, with the normal construction of the ventilation channel, there should be that thing.

Sure enough, on the side of the destroyed wall, there was a staircase made of coarse steel, which was extremely simple, and because of the location on the side of the destroyed wall, they could not find it at first sight, so they could only find it when they leaned out and looked closely.

Although he said so, this simple iron ladder was obviously not very strong, and even Yu himself did not dare to guarantee whether he could bear the weight of such a big man as him, but it seemed that there was no good way to do it other than this method, and after thinking about it, Yu decided to take the risk and try it first.

At the bottom of this ventilation channel, there are gusts of strong wind rushing up. Looking at it, it is bottomless, and it is estimated that if it falls like this, it will not be able to see the sun tomorrow, even Su Xiaobai looked at it. I couldn't help but tremble in my heart.

Su Xiaobai knew that the simple iron ladder seemed to be gone below a certain height below, if she really fell, she would be able to come back to life without dying, but she would not be able to climb up from underneath, she would only be trapped below until she could not be resurrected. Thinking about it, Su Xiaobai couldn't help but shiver several times.

"You wait here, I'll try it on the ladder. If you can withstand our gravity on it......" As he spoke, Yuu's gaze fell on the most suitable position to climb on, and the gun had already been tucked back into his waist, half-leaning out. Sideways. Facing the wall, his right hand stretched out, but he didn't expect that the distance of the iron ladder was a little farther than Yu predicted, and his fingertips were still not a centimeter or two away from touching.

Fighting, you must have a certain look, gritted your teeth fiercely, and suddenly suddenly lifted your breath and jumped under your feet. Then he jumped up a little distance, and his right hand suddenly grabbed the thick iron in a thousand shots. There were a few 'bang bang bang' sounds, and Yu just hung in mid-air, and Su Xiaobai's heart tightened uncontrollably, but he didn't dare to move his eyes, for fear that something would happen that could not be rescued in the blink of an eye.

Taking a deep breath, You's right hand was slammed into force, the muscles on the forearm of his right hand were protruding, and with a kick of his feet, he was firmly attached to the iron ladder, climbing up and down for several steps, Youcai slowly breathed a sigh of relief, it seems that although this iron ladder is a little old, fortunately, this ventilation channel is relatively dry, and there is no rust, and it can bear the weight of a big man like him.

As long as his weight can withstand it, it is even more difficult to withstand Su Xiaobai's weight, it seems that if there is no accident, they can indeed climb out like this, thinking about it, You is stretched out his hand to Su Xiaobai, and his eyes signaled.

Su Xiaobai pursed her lips, at this distance, even if she jumped up, she was a little reluctant, saying that there was no worry and fear in her heart was fake. But Su Xiaobai knows better than anyone that if you want to live, you must have the courage to live.

So, she took a few deep breaths, her eyes stayed on You's body, she let out a low snort, her feet kicked suddenly, her body instantly took off, and the gale that suddenly surged up from under the ventilation channel made her eyes close unbearably all of a sudden, her black hair was even more messy, and her heart was suddenly even higher.

In the next moment, a powerful force suddenly pulled her body over, and she was crashing into a slightly stiff embrace, and her hands and feet were finally able to have something to climb on, so she dared to open her eyes slightly, and you were slightly behind by a few steps, allowing Su Xiaobai to take the lead.

This action, You's doing it is extremely natural and doesn't leave a trace, it looks more like it's just a good adjustment of the climbing position of the two, but I didn't expect that this is You, who has always been bent on going his own way, has a lot of thoughts, as long as Su Xiaobai accidentally does something, he can still hold it in the back.

All the way forward, I don't know how many floors the basement is, so it takes a lot of time to go all the way, the two of them are climbing one after the other, but the palms of their hands will inevitably be touched by the rough iron that has not been processed much, and the palms are even more hot and painful, but Su Xiaobai still endured them one by one.

I don't know how long it took for them to reach another vent that leads horizontally into the interior, and they don't know how many layers of vents it is, but in this situation, there is no better option than this one.

At the bottom, Yu is supported by this strength, and Su Xiaobai was lifted, and he himself came in from behind, and his increasingly tired physical state could not be concealed, as soon as they arrived at the vent, the two of them were a little weakly paralyzed, gasping for breath, unable to say anything.

It's just that they didn't stop for more than ten minutes, and they didn't have time to explore deeper into the vent, but an accident happened suddenly.

Only a few loud, violent explosions were heard, Su Xiaobai and You both felt the shock conveyed here, as if the whole building trembled a few times, Su Xiaobai almost didn't climb and fell straight out, turned around, but met You, who was also shocked in his eyes, and only heard You's voice couldn't help but be low, "What happened, why did such a violent explosion suddenly happen, and even this place was alarmed?" ”

"I don't know," Su Xiaobai shook his head, "but I always feel that something big should happen......" (to be continued......
