A well-known math problem in ancient China: there are pheasants and rabbits in the same cage, with thirty-five heads on the top and ninety-four feet on the bottom.

——Excerpt from "Essays of Ling Zikai"

After the eight-tailed spirit fox got the fowl cloak, he went straight to the abyss of the weak water of Kunlun Hill.

Handing the fowl cloak to the blue bird, the blue bird happily took the eight-tailed spirit fox to fly over the abyss of weak water. There seems to be a looming "door" in front of us, standing there.

The abyss of weak water is followed by the "Nine Gates of Kunlun Hill" located on the mountainside of Kunlun Hill, which is a gentle slope of the mountainside, extending in all directions, and is the place where all parts of Kunlun Hill are connected. On the Yao Pond, the hanging garden, down to the abyss of weak water, the left and right roads connect the peaks of each road, and the nine wells of Yulan. In the center of the Enlightened Beast Town.

The enlightened beast has nine heads of tigers, and all nine of them are human faces.

The Enlightened Beast is a tiger-like beast with a head and a human face on it. It's another nine-headed beast, different from Xiangliu as a demon beast, this enlightened beast is a divine beast!

After passing through the "gate", and entering the eight-tailed spirit fox in the realm of the Nine Gates of Kunlun Hill, there was a creature squatting like a fierce tiger with nine human faces!

The head of the Enlightened Beast, which is in the center of its nine heads, spoke: "I have been ordered to guard this 'Nine Gates', and if you answer the questions posed to my head, you will be able to pass through the corresponding 'Gate'!" You choose my head to answer the question! ”

Lingzi scratched his head, nine songs correspond to nine "doors", and if you answer a question correctly, you can get the corresponding permission to pass through a "door", so the "door" corresponding to the abyss of weak water that you entered, how can it be counted?

Lingzi controlled the eight-tailed spirit fox to choose the head of an enlightened beast at random, and the head of the enlightened beast spoke: "The mountain-shaped mountain, there is a beast, its shape is like a dog, six-legged, and its name is Congcong." The mountain of prayer, there are birds, its shape is like a plover, the white head is three-legged, and its name is called Quru. Today, there is a courtyard from Cong and Qu, there are a total of 36 on it, and there are a total of 141 under it. ”

Lingzi looked at the title for a moment, and immediately understood its meaning. Isn't this the question of the same cage of chickens and rabbits in the version of the Classic of Mountains and Seas?! Fortunately, this is a single-headed creature from Yu Quru.

It's easy to answer this kind of question! The cong cong and Qu Ru who erected the yard both lifted three feet! Then a total of 35 * 3 feet were raised, and the total number of feet 141 minus the 35 * 3 feet raised is equal to 36 feet, and these are the feet of the slaves who are currently standing on three feet, so dividing 3 by 3 from a total of 36 equals 12! The total number of heads is 35 minus the number from 12, which is Qu Ru only counts 23!

After mentally arithmetic the edges of the answer, I directly selected the correct answer option.

The head of the Enlightened Beast's question, slightly surprised, said, "You're right!" ”

Subsequently, a "gate" appeared on the west side of the mountainside. Pity! It's not the direction you want to go! The Jade Mountain Peak is on the north side!

The eight-tailed spirit fox was a little bit enlightened by another song, and the head asked: "The eight different beasts are running to the ground together, and the eight-tailed spirit fox has surpassed the second place, and asked you how many places you are now?" ”

Prism Khan! The math problem of the previous version of the Classic of Mountains and Seas in the same cage of chickens and rabbits has now changed to the brain teaser of the version of the Classic of Mountains and Seas?!

Legiko directly chose the second place.

The other head of the enlightened beast bowed its head and acquiesced, and another "door" appeared in the southwest of the mountainside. It's not the target of the eight-tailed spirit fox.

Another enlightened beast leader asked the third question: "The three mulberry trees, in Ousidong, are a hundred feet long, and have no branches. The mountain of the long right, there are beasts, good at climbing, its shape is like Yu and four ears, its name is long right. The long right climbs a thousand on the day, and falls eight feet at night, and asks the long right how many days can reach the top of the three mulberry woods? ”

It's another math problem, but it's not! The tree called Sansang has no branches and leaves, and is as high as 100 feet. Now "hundred" is used to describe extremely high or deep adjectives, ancient 仞 is a unit of length, eight feet for one thousand. And the long right shape is like Yu and four ears, it is a four-eared monkey, climb a thousand during the day, drop eight feet at night, play in vain! It's back again! It is estimated that the reason is very simple, the three mulberry trees have no branches and leaves, and the monkey can barely climb the tree during the day, but when he falls asleep at night, he slides down!

Ridge chose the "unreachable" option, and this time the "door" lit up from the direction behind it. Good! This is the way back to open first!

Lingzi chose the head of the enlightened beast for the fourth time, and the other party asked: "The father of the blue bird, there are three sons, the eldest is called the big eagle, and the second is called the young eagle, what is the name of the third child?" ”

Another brain teaser?! The Queen Mother sat down, and the names of the three blue birds were all announced!

After the eight-tailed spirit fox chose the answer to the blue bird, this time it was the "gate" on the north side of the nine gates of Kunlunqiu that appeared!

The four questions opened the direction you want to go, and your luck is okay! No longer continuing to answer the question, Lingzi controlled the eight-tailed spirit fox to pass through the "gate" leading to the Jade Mountain Peak on the north side of the Nine Gates of Kunlun Hill.

……

Kunlun Hill Jade Peak.

The eight-tailed spirit fox that passed through the nine gates of Kunlun Hill is walking along its mountain road and looking at the cave halfway up the mountain.

Outside the entrance of the cave, two blue birds in front of the abyss of weak water were similar in appearance, and the same blue birds with black eyes and bright colors stood on both sides of the cave entrance.

One of the blue birds spoke, "We know that you have passed through the mountain of fire and the abyss of weak water, and you have passed through its gate with enlightenment. Thou shalt enter the cave and see the Queen Mother. ”

The eight-tailed spirit fox bowed to the two blue birds to express their gratitude, and then entered the cave.

The cave where the Queen Mother of the West lives is not too ornately decorated, and the cave is not very deep, and the eight-tailed spirit fox did not go too far to the end of the cave.

The Queen Mother of the West is a congenital spirit body, wearing a jade sheng on her head, leaning on a jade case, with tiger teeth and leopard tails, showing a solemn and murderous atmosphere. There are four divine beasts under the seat, divided on both sides, the left side is the three-legged black and the golden toad, and the right side is the white rabbit and the nine-tailed fox.

The eight-tailed spirit fox automatically stepped forward to tell the reason and what he was asked for.

The Queen Mother of the West shook her head: "My Si Tian is powerful and the five remnants, there is no way to bring the dead back to life!" ”

The nine-tailed fox standing on the right stepped forward and knelt down, helping to intercede: "This of my people, please ask the queen mother to be gracious!" ”

"Alas!" The Queen Mother of the West sighed, "I don't have a way to bring the dead back to life, but I have this medicine of immortality!" This magic medicine, the living eat it, and they can live forever! Or you can bring your people back to life! Although you have passed the test of Kunlun Hill, if you can pass the test of I have given you another one, I will give you an immortal medicine! ”

The eight-tailed spirit fox directly accepted and said, "I am willing to be tested by the queen mother!" ”

The Queen Mother of the West nodded, and the white rabbit stepped forward and said: "In the past, the young man was not talented, and his name was 'Poor Qi', who ruined his faith and loyalty, and admired evil words. After his death, he left a grudge in the world, and turned into a fierce beast is also a 'poor strange'. Today, the poor and strange are the one who is in trouble, and they are good at cannibalism. Although it is transformed by resentment, it will not die or die, but it will defeat its body, but it can also protect the people of one side and have no worries for a hundred years. Would you like to go to the town? ”
