Carefully removing the shell of the latter, Li Qing breathed a sigh of relief in his heart when the two short sections of wires, one blue and one red, were exposed.

Fortunately, this style of timed thunderbolt bomb is generally very easy to solve, what he was most afraid of before was that the girl just left behind that kind of electronic or chemical mechanical type of these high-tech things, in that case, Li Qing absolutely didn't say a word, and immediately slipped away, because he wouldn't solve it, but if he used the most basic timed thunderbolt like the parallel resistor in front of him, then it was Li Qing's turn to show his skills.

The most primitive timed thunderbolt circuit is a parallel circuit with two branches, the explosives (called the detonator in technical terms) are placed on one branch, and the other branch is a wire, without resistors. According to the principle of physical circuits, in the face of two wires, the electricity will all run along the one without resistance, and the wire with resistance is the detonator of the timed thunderbolt, once the wire is energized (such as cutting the wrong wire), it is the moment when the thunderbolt detonates, so what Li Qing is looking for at this time is the wire with resistance.

In order to prevent his actions from being foolproof, Li Qing repeatedly considered these two wires, although he had already seen the number of these two wires, but he still hesitated for a long time before gently cutting the small scissors in his hand.

Gently taking off the thunderbolt bomb and carrying this thing in his hand, Li Qing suddenly sighed, shook his head gently, and sighed in his heart: The young people nowadays are really terrible, can this timed thunderbolt be played casually? Fortunately, I found it in time, otherwise I was blown up here out of thin air after entering the tunnel, who would I talk to to reason?

Putting aside the thunderbolt in his hand, spreading out the map in his hand, and sketching the map that was almost complete on it, Li Qing put away the map and prepared to return to the base to make a difference, such a detailed map is enough to explain a lot of problems, I believe that the Picheng woman will not embarrass herself again.

After obtaining the Mercury Boots, Li Qing was ready to leave here, first rescuing his senior brother and finding out his whereabouts was the most important task at present.

So, Li Qing turned all the way back along the original road, because Li Qing had already walked on the side of the previous road, so the pace under his feet was also very fast, but when Li Qing returned to the other main roads that he had walked not long ago, Li Qing suddenly found that something was wrong.

Just now, where he had walked, there was another ticking sound in his ears.

Hearing this familiar voice in his ears, Li Qing slowly looked into an inconspicuous corner above his head, and suddenly thought of what the girl had said just now.

"You're a little late to find out......"

Oops, something is going to happen!

Listening to the familiar voices around him, Li Qing secretly screamed that it was not good, the current situation was beyond his control!

There were so many thunderbolts, Li Qing didn't know how the girl filled the tunnel in such a short period of time by herself, it could be that she didn't care when she walked before, or it could be other reasons, but now this situation, he had to hurry up and report it to the person Caitlin, this may be a premeditated and dangerous case prepared in advance. In order to maximize his speed, he even released the angel wings behind him to accelerate, and the girl with the loli pigtails just now was by no means as simple as an ordinary naughty girl.

It's no wonder why Picheng was so heavily defended before, and the attack here seems to be quite serious.

The underground tunnel that Li Qing was staying in was an area located in the center of Pi Cheng, and according to the inscription on Li Qing's map, this tunnel was just below the intersection where he entered, because the route Li Qing planned was to go around Pi Cheng. Therefore, under the running of Li Qing who chose the nearest straight line to accelerate all the way up, it didn't take long for Li Qing to come to the surface.

At this time, the sky was close to darkness, which indicated that Li Qing had been in the underground tunnel for a long time, Li Qing followed the route he took when he came, and went straight into the person, the base did not seem to be off work at this time, Li Qing remembered the office where Caitlin was before, and because of the daytime visit, many uninformed people recognized this white-haired boy as if he had something to do with his boss. So for a while, under the pull of those "insiders" and their colleagues not to stop them, Li Qing entered Caitlin's office all the way unimpeded.

Due to the urgency of the situation, looking at the office door, Li Qing didn't think much about it, and casually pushed it open and rushed in.

With a bang, the office door opened.

"Miss Caitlin, I found this in an underground tunnel...... Belch? ”

Li Qing rushed into the latter's office in a hurry, only to find that Caitlin was reading a document at this time, and there was an extra person next to her.

It was a woman with pink hair, and when she saw Li Qing walk in without saying hello, a pair of huge mechanical fists suddenly appeared in her hands, and her sharp eyes instantly made Li Qing's back chills.

Caitlin was also startled by Li Qing, who suddenly broke in, but when she saw Li Qing holding a shark mouth pattern on a timed thunderbolt in her hand, her complexion suddenly changed.

"Wait, Vi!" Caitlin hurriedly called out to the tough woman next to her, who was already preparing to clean up Li Qing's unsightly miscellaneous fish, and looked at Li Qing, who was standing at the door a little overwhelmed.

"Mr. Twilight, are you done walking through the underground tunnels? Is the map drawn? Caitlyn asked.

Li Qing nodded, the space ring in his hand flashed, and a densely drawn map suddenly appeared in Li Qing's hand, but he didn't dare to just walk towards the woman, because he was indeed a little cowardly by the eyes of the strong eldest sister next to him.

Looking at Li Qing who was standing in place and taking out the map, Caitlyn gestured to the woman named Wei next to her, Wei suddenly nodded slightly, walked in front of Li Qing, picked up his map, and glanced at Li Qing coldly, then turned around and took the map towards Caitlin, Li Qing's impolite behavior just now made her impression of Li Qing very bad.

Seeing the map in Li Qing's hand, the complex lines on it made Caitlin's eyes suddenly appear a look of shock, and even the thunderbolt that Li Qing took out earlier was temporarily put aside. First of all, such a detailed and complex map is by no means possible for ordinary people to draw, and in less than a day, Piltover's underground tunnels can be depicted in such detail, this guy is simply a scout genius!

Wei's eyes also began to glance at the map a few times with Caitlin's observation at this time, because she went out on a mission in the afternoon, so she didn't know what was agreed between Li Qing and Caitlin, but Li Qing suddenly took out such a detailed map of the underground tunnel of Piltover, and the surprise in her eyes still couldn't help but be revealed.

Because of this map, in addition to the one in front of him, the other person who owns it is the brightest scientist in the whole of Piltover.
