When these people used smoke grenades, Qi Xibei immediately had a different thought.
It must have something to do with Qiao Yanyu!
After all, she had never seen people here make oxygen tanks and smoke bombs before.
Other than Qiao Yanyu, there should be no one else with such strength and knowledge.
Regardless of whether it was true or not, Qi Xibei would not let this lead go.
She carefully followed behind these people to understand the situation.
They moved very quickly. It was obvious that they were very familiar with this place. Even in the dark, it did not affect their progress.
After a while, they stopped in a cave.
Princess Ruyi and the others would not be able to find this place.
Qi Xibei carefully hid his figure. He absolutely could not let them discover him.
Then, these people checked the surroundings. After making sure that there was no one around, they began to speak.
"He actually failed!"
