The fishing boat retreated from hole 6.

Asarina is in good condition, and Teacher Cheng is a little worse. I don’t know if it’s because she is older, she is a little bit confused and has poor energy.

The boat stopped in front of seven caves.

Pan Xiaoxin looked at Bai Youwei with uncertainty: "Sister Weiwei, which hole should we... enter this time?"

They have passed the 4th and 2th, and now the 6th cannot pass, so they have to face the choice again.

Bai Youwei looked at the cave in front of her and asked Pan Xiaoxin: "Xiaoxin, what rules do you think do you have between 4 and 2?"

Pan Xiaoxin was stunned, "It's all even numbers, and then... only one digit is separated in the middle?"

Bai Youwei said: "Count from right to left, there is a 3 between 4 and 2. If the next cave is the same rule, count from 2 to forward, which hole should we choose?"

"…7?" Pan Xiaoxin said uncertainly.

Asarina asked, “Is it a big grasp of 7?”

"It's hard to say." Bai Youwei lowered her eyes and whispered, "Just under the boat, I saw a pattern of an isotrosnake printed on the boat, with seven in total. Near the isotrosnake is a pattern of a mermaid, just like... Once you leave the isotrosnake, you will be attacked by a mermaid."

Pan Xiaoxin had never got off the boat and had not seen those patterns. After hearing Bai Youwei's words, he couldn't help but realize:

"I understand, the seven weaver snakes correspond to seven caves. Is that true, Sister Vivi?"

Bai Youwei nodded slightly, said with a low "um" sound, "No matter how we choose the seven caves at the beginning, we will never encounter mermaids. It is because we are in the position of the snake's head. Each snake's head can ensure our safety. But once we go deeper and enter the snake's belly, it is equivalent to choosing a ring-shaped closed path. We must follow the corresponding path of the weebosnake, otherwise we will lose protection."

Aaron couldn't help asking: "But how can we know the corresponding path of the snake? Are there any hints in the pattern?"

This is the most difficult thing for Bai Youwei.

Because the pattern on the ship was entangled with a group of snakes, and the light was too dark, it was really difficult to see the details clearly. Moreover, with the mermaids attacking the ship several times, the pattern was severely damaged, and the iron sheets in some places had been peeled off.

"The corresponding paths of each weebosnake should have their own rules... I can't see obvious hints, but their colors are black and red, one black and one red. If the head is black, then the tail must be red, and the color is just cycling."

Asarina thought: "If the order of entering the hole is also circulated like a color, enter hole 4 and push the two numbers forward to be No. 2, then No. 7, No. 5, No. 3, No. 1, No. 6, and No. 4. We need to enter the hole 8 times in total before we can cycle back to the original No. 4 position."

Bai Youwei nodded: "That's what it means."

After a pause, Bai Youwei said again: "Count from right to left, 4 and 2 are separated by a number, count from left to right, 4 and 2 are separated by four numbers."

1-2-3-4-5-6-7.

Ashalina nodded after hearing this, "I understand. What you mean is that at the beginning, you choose the number of holes, and the next hole will be selected as the number of intervals. If we choose hole 1 at the beginning, then the next hole will be 3, followed by 5, 7, 2, 4, 6, 1. It also takes eight times to achieve a cycle."

"This is just a possibility of regularity." Bai Youwei's voice lowered, "Do you want to choose a cave according to the color prompts? Let's talk about your views."

Ashalina thought for a while and looked at Aaron: "Go down and see how many color blocks there are in the weaver snakes."
