Song Qingyu carefully observed the terrain near the flame slurry, and made a simple inference based on the map.

If the group wants to get up from here, she has to find a way to climb the rock, or she has to figure out the mechanism here and climb up little by little.

However, in this way, their speed will be much slower, and it will take a lot of time to get up from here just for a month.

Take some fire spirit stones here first and then go up, Song Qingyu made a decision after careful consideration, spending so much time here, naturally he wanted those things to go again, and he couldn't do things that didn't work in vain.

"Miss Song, what should we do now?" Erxi waited there for a long time and didn't wait for Song Qingyu to go back, and they were also a little anxious, so they took the initiative to come over and ask.

Song Qingyu looked at the flame slurry pool and said slowly, "I'm thinking, is there any way to pass through this hole." ”

Everyone also looked at the pool of flame slurry, and the flame slurry at the entrance of the cave flowed into it in an orderly manner, and the position of the flame slurry had also improved to a certain extent, and they knew that it was because there was something underneath it.

"Miss, have you figured out what to do?" Erxi asked.

The other little brother took the initiative to come over, walked to the side of the flame slurry pool, and squatted down to observe carefully.

"Not yet, the entrance to the cave is half blocked, it's hard to imagine, how could Yuanmou think of using people to block this method." Song Qingyu said.

Qiao Lingling walked over empty-handed, Erxi insisted on helping her get something, saying that boys can't let girls suffer here, she couldn't refute it, so she handed the bag to Erxi.

"Hmm......" The little brother observed the cave carefully, his mind was calculating rapidly, he suddenly stood up and asked Song Qingyu, "Miss, can you show me your map?" ”

Although he didn't understand what this guy was going to do, Song Qingyu still handed over the map.

The younger brother observed for a while, and suddenly asked, "Miss, do you have any pens with you?" ”

Song Qingyu looked at Qiao Lingling, who shook his head, "Come out to explore, how could I bring that kind of thing." ”

"Do you have any plans?" Song Qingyu asked.

"That's right." The younger brother explained: "Miss, according to my observation, I found that this flame slurry pool has a regular outflow pattern, and every few minutes, the flow rate of the flame slurry pool will weaken, but I need to calculate the specific time. ”

"Calculations? How do you count this? Song Qingyu looked puzzled, her math was not very good, but she was only in high school, she had only read some books, and she had not explored it in depth.

"Miss, you don't have to worry about this, you just need to find a way to find something for me to write, I'm in charge of the calculation, what Yuan Mou said about using people to block this flame slurry is a certain reason, the outflow of this flame slurry pool is not here, so as long as we calculate, calculate the exact time, and seize the opportunity, we have a chance to pass through this cave."

What the younger brother said was the Tao, but Song Qingyu didn't understand much.

Qiao Lingling was also confused, she didn't go to school and directly helped the family, she couldn't understand these profound things.

On the other hand, Erxi understood it, and he asked, "This amount of calculation is a bit large, can you do this?" ”

Speaking of this, the younger brother looked proud, "Don't worry, this kind of calculation is nothing to me." ”

Song Qingyu saw the confident appearance of the little brother, and some appreciation, it seems that the person in front of him also has some skills in hand.

She asked rarely, "I haven't asked your name for so long, what's your name?" ”

The younger brother replied, "Miss, my name is Yang Feng, the Yang of the poplar tree, the wind that blows. The latest chapter of "Rebirth of the Strongest Female Fairy Venerable Claw Book House in Modern Times" is free to read for the first time.
