The other three didn't speak, they just looked at Feng Jianfei with a nervous expression, Feng Jianfei's analysis just now was more reasonable, and they had no reason to stop it. Pen, fun, and www.biquge.info

"Zhong Hao, look carefully. As soon as Feng Jianfei's words fell, his feet had already stepped up the first staircase, and when Zhong Hao turned his head to look at the location of Feng Jianfei's stairs, in the blink of an eye, Feng Jianfei had already passed through the stairs to the second floor, and nothing had happened to the location of the stairs.

"Captain, what's going on up there?" Zhong Hao turned his head forward to the stairs, wanting to see Feng Jianfei.

"Be careful!" Feng Jianfei shouted anxiously, and several feather arrows shot out from all directions of the stairs, which happened to be in the direction of Zhong Hao's head.

"I'm scared to death!" Ke Feng kicked Zhong Hao to the side, and those arrows landed right where Zhong Hao was standing just now.

"Haozi, how are you?" Feng Jianfei had quickly jumped down from the top and asked nervously.

"Get out of the way!" Zhong Hao pushed Feng Jianfei hard, and shouted loudly, the sound of arrows cutting through the wind behind him.

Feng Jianfei was the first to react and took Zhong Hao backwards, and just hid in front of the last room, and a few feathered arrows fell to the ground. The arrow has been completely inserted into the floor, and the force can be seen.

"Captain, are you all right?" Du Xiaoling and Ke Feng were in a safe position just now, so they were fine, and hurriedly ran to Feng Jianfei and Zhong Hao's side.

"It's okay!" Feng Jianfei stood up by himself and moved, indicating that he was fine.

"Fifteen seconds, twelve seconds, why?" Zhong Hao read silently.

"Haozi, what are you thinking, are you okay!" Du Xiaoling was the first to hear Zhong Hao muttering to himself.

"Lao Du, why did you suddenly come out from behind and want to scare people to death!" Zhong Hao was interrupted, a little dissatisfied.

"Haozi, I'm just asking what you were muttering about. Du Xiaoling probably didn't expect Zhong Hao's reaction to be so big.

"Captain, I found out that there is a question, the first time you shoot out is fifteen seconds, the twelfth second, why is the time different? Will the time be shorter and shorter in the future?" Zhong Hao's words made everyone fall into deep thought.

Haozi's analysis makes sense. Du Xiaoling was actually quite surprised, Zhong Hao was standing in a more dangerous position when the feather arrows flew over twice, and it was really not easy for him to remember to calculate the time in this case.

"Captain, come and take a look, the first time the captain passed a total of more than two seconds, the captain shared four steps, the first left foot stepped on the third step, then the right foot stepped on the sixth, the left foot stepped to the ninth step, directly to the top, a total of four steps. And then. Zhong Hao walked up to the stairs and said.

"Haozi didn't expect you to remember it so carefully. Ke Feng patted Zhong Hao on the shoulder behind him.

"What else have you discovered?" Feng Jianfei looked at Zhong Hao, and he intuitively felt that Zhong Hao must have made other discoveries.

"Captain, how many feathered arrows are there here?" Zhong Hao wanted to pull out the arrows on the ground with his hand.

"Haozi, don't move. Ke Feng next to him slapped Zhong Hao's hand away, mainly because Cui Yongzhong's poisoning and death left too much shadow.

Four roots, four steps, ・・・・・" Feng Jianfei stared at the arrows that were neatly inserted in a row on the ground.

"It should be like this, when the captain jumped down just now, the first part of the eighth staircase, and the second went directly to the ground. , you see that there are only three of them here, so can you prove that the number of feather arrows you shoot is the same as the number of steps you take to go up this ladder?" Zhong Hao asked rhetorically.

"Haozi, there is another question, why are these arrows shot out in a column?" Ke Feng asked as he looked at the two rows of arrows on the ground.

"It's not hard to explain this question, you can see that the first arrow shot here is from the third, sixth, and ninth steps. This one is shot from above in the last one, at the rear. Zhong Hao pointed to the last feathered arrow and said, "This one is shot from the position of the ninth step." This one is sixth, this one is the third. Zhong Hao pointed to the first row of arrows and said one by one.

"Haozi, what do you mean?" Feng Jianfei stared at the arrows, as if confirming something.

"I don't know, these arrows were shot from the bottom left corner of each staircase, I don't know if this has any effect. Everyone followed what Zhong Hao said, and sure enough, there was a hole in the lower left corner of these steps that was pierced by an arrow.

"Haozi, what do you mean?" Feng Jianfei stared at the arrows, as if confirming something.

"I don't know, these arrows were shot from the bottom left corner of each staircase, I don't know if this has any effect. Everyone followed what Zhong Hao said, and sure enough, there was a hole in the lower left corner of these steps that was pierced by an arrow. , which is enough to prove Zhong Hao's analysis just now.

"You can see that these positions are also shot from the stairs that the captain has stepped on, but the arrows do come out of the middle, so I don't quite understand what they mean. Zhong Hao usually looks like he is brave and unscrupulous in everyone's minds, and he may worry a lot of times about whether he has caused some trouble again, but now everyone is a little stunned by his analysis.

"Position shouldn't be the most important thing now, I guess time is the most important, how much will the next time become?" Have you ever thought about this question?" Feng Jianfei had been thinking about this question just now, as long as they could avoid the time when the feather arrow was fired, there would be no problem.

"The captain is right, but what is the next time? ”

"Wait a minute, time time, I know!" Zhong Hao said loudly, "This time the time should be ten and a half seconds." Zhong Hao suddenly realized.

"Haozi, how do you know?" Ke Feng asked.

"The first time the captain went up to activate the mechanism was fifteen seconds, the second time was twelve and a half seconds, and the time it took the captain to go up for the first time was two and a half seconds, does it mean that the time left is equal to the time at the beginning minus the time used?"

"Haozi, how did you get smart after a good night's sleep?" Du Xiaoling said with a laugh.

"Alright, now we should assign a figure on how to get up, and we'd better be able to get all up in ten and a half seconds. ”

"The captain wants to go up in ten and a half seconds, but this is the only way, Lao Du and I go in front, the two of us go forward at the same time, Haozi follows behind, and the captain lasts, so maybe we can all go up before the next mechanism is activated. Ke Feng analyzed.
