But it is said that above the heavenly court, the high heavenly saint and the benevolent Jade Emperor and the great heavenly Venerable Xuanqiong are high God, sitting high in the Lingxiao Treasure Hall of the Jinque Cloud Palace, and are summoning the Qing family, setting the number of good and evil in the world that day, wind and rain, and suddenly saw the You Yi Lingguan who came to report was rushed by the purple qi vacated by the nether realm, fell from the clouds, fell, and said in surprise: "How can there be a purple qi in the world, blocking the way to and from the immortals?" Clairvoyance, Shunfeng Ear, you go outside the Nantian Gate and see what is going on! ”

Before the two gods could leave, there was a report from Tai Bai Xing: "Your Majesty, don't worry, this matter is a little minister!" This is the thirty-three days away from the hatred of the heavenly dou rate palace Taishang Laojun, yesterday reincarnated in the earth, to educate the world, he completed his deeds, went to the West Heaven to turn Hu into a Buddha, the saint traveled, his own purple gas with him, 30,000 miles long, so he can collide with the heavenly palace. ”

The Jade Emperor said: "I see, but I see that this purple qi is divided into two strands, and it is a little strange. Then he ordered the ears of the wind and the clairvoyance to explore again.

The two gods will report back: "The minister was ordered to visit the westward place of Lao Jun, and he had reached the boundary of Zhou Hangu Pass of the Middle Earth Sect, but he saw Lao Jun riding on a bull, and there was a young saint walking side by side in the same car, living on the right side of Lao Jun, so the purple gas from the east followed him for 30,000 miles, in the shape of a dragon and tiger, and he was angry and bullfighting, which disturbed the Heavenly Palace. I just don't know where the saint came from! ”

The Jade Emperor was surprised: "Oh? How rare is it? The two saints traveled west together to educate sentient beings, which is really a fortunate thing for the Three Realms, and the Qing family can know the origin of the young saint's feet? ”

The three official emperors and the four value gongcao probed their ears one after another, the four heavenly masters looked left and right, the five senses gave birth to the emperor, the four generalissimos looked blank, the five dipper star monarchs, the six dings and six jia looked at each other, and the twenty-eight stars of Jiuyao only shook their heads, or the Tai Bai Xing came out of the column and said: "That young saint, the minister has heard of it, can be on the right side of the old monarch, and dress up as a teenager, it must be thirty-three days away, Fusheng Immeasurable Heavenly Venerable, Duren Immeasurable Heavenly Venerable, Merit Immeasurable Heavenly Venerable, Guangfa Immeasurable Heavenly Venerable, Ten Directions Immeasurable Heavenly Venerable, Da Luo Immeasurable Heavenly Venerable Chen Sect Master incarnation." ”

"The Immeasurable Heavenly Venerable has not seen this world, it must be the old monarch who came to the world, alarmed him, and descended from the sky to incarnate and travel west together."

The Jade Emperor gave mercy and said: "Since you are the master of the Heavenly Sect and have great merits, it is not enough to be surprised!" Tai Bai Xing intended to say something more, but when he saw the Jade Emperor lowering his eyes, he opened his mouth, but he didn't make a sound, just sighed secretly in his heart and returned to the rank of the hundred officials.

In Hangu Guanzhong, Yin welcomed the two saints into the official residence temporarily, in addition to handling official business on weekdays, he went to the old monarch's seat day and night to listen to the lectures, but he was afraid of Chen Ang, and did not dare to ask for advice, except for the two saints who listened to the lectures when they were arguing, and never asked Chen Ang alone. He is the Hangu Pass Order, Lao Jun goes west, and he still needs to be released, he asks for advice like this, but he leaves Chen Ang, Lao Dan in recent months, although there is a suspicion of strong guests, but he is polite and thoughtful, and he can not blame him for saying goodbye in the morning and evening.

This month, Chen Ang has a lot of free time, so he often teaches Wukong.

He talked with Wukong about the emptiness of Buddhism, the wonder of mindfulness, the three wonderful truths, the truth of the six roots and nine consciousnesses, starting from consciousness, saying that there is no self outside the mind of Buddhism, there are impermanence of all actions, there is no self in all laws, and the theory of nirvana and extinction, and said that the wonder of dependent origination, the twelve causes and conditions are the self of consciousness, the process of birth from nothing, and talked about the Tao giving birth to one, one life two, two giving birth to three, three giving birth to all things, and the truth of one qi transforming the universe, and also taught the three tombs and five classics, eight ropes and nine hills, Lianshan, Guizang, Zhou and other changes.

When he has spare time, he also teaches it the method of burning fire and alchemy, making tools for law, and practicing qi in talismans.

After closing the door every day, teaching the natural philosophy of all sciences, the monkey's head jumped out of the uncertain, when teaching mathematics, the most painful, Chen Ang out of the exercises to let it practice, but learn the function equation, let Wukong feel pain, algebraic geometry, almost let Wukong skip school, this day, Wukong returned from herding cattle outside the gate, suddenly Chen Ang saw, called him over.

asked, "Wukong, take out the homework I left yesterday!" ”

Wukong shouted: "Master, the disciple didn't finish his homework all night yesterday, and when he was herding the cow today, he was just finished writing, and he was so tired that he fell asleep on the back of the cow, and suddenly a gust of wind blew the disciple's homework away!" ”

Chen Ang smiled coldly, pinched his fingers, and after a while, he opened his eyes and glanced at Wukong, and said: "I already know who the wind is, Hangu Pass has been an important town in Xiongguan since ancient times, Qin Zu was a horse herder for Zhou Tianzi, and before he became a princely power, the dog Rong entered the Central Plains several times, and all of them fell under Hangu Pass, and the white bones fell in the valley, breeding poisonous insects. ”

"There is a horse and land insect under the pass, nourished by the carrion of the dead, and become fine over time, calling himself the general of Ma Lu, agitating the yin wind every day, cruising between the Dasan Pass and the Hangu Pass, looking for people to secretly kill and eat, the wind you see today is the demon wind he blew, to fascinate the eyes of the business travelers, so that they stumble and fall into the valley."

Chen Ang only waited for dusk, then got up and went to the upper floor of Hangu Guancheng, watching the scenery outside the pass, there was a rolling demon wind blowing outside the pass, Chen Ang had a hand, between his fingers to stimulate the vitality, causing the vitality to jump high-energy, turning into light, only to see a red light as thin as a finger shook into the demon wind, and a thousand-foot demon insect as thick as a person fell down from the air.

Wukong next to him took a closer look, but saw that the thousand-legged horse was evenly split in half from beginning to end, and his hands and feet were still moving, but he had already returned to the west.

Chen Ang raised his hand to take a photo, and took a roll of yellow books wrapped in the fallen debris in the demon wind, and opened it to see that there was not a word.

Immediately sneered, ordered Wukong to roll over, the monkey's head trembled, helpless, knelt at Chen Ang's feet in embarrassment, and shouted: "Master, master, the disciple is wrong!" The disciple is wrong! Ask for forgiveness...... Forgiveness. ”

Chen Ang only said: "If you don't want to learn, then forget it!" You are also full-fledged, and you have learned a lot of magical spells, and what I teach later is nothing more than limits, calculus, spatial analytic geometry, linear algebra, series, ordinary differential equations, if you don't understand these, then fluid mechanics, advanced physics, space physics, high-energy physics, quantum physics, advanced chemistry, you can't learn it, and what you can teach for teachers is here. Go ahead! ”

After saying that, he waved his sleeves and turned around to leave, Wukong hurriedly hugged his legs, and said with tears in his eyes: "Where did Master teach me to go?" ”

The sound was like an ape's cry, crying silently, the green cow also came over, grabbed Chen Ang's sleeve, nodded and pleaded for it, Chen Ang only said: "Cultivate what I have learned, those who don't know mathematics are like burning porcelain but not fire, it seems to have an appearance, but in fact it is just an embryo." When you worship me, just to learn the art of immortality, this kind of mathematics, you can't live forever after cultivating, you just can ask for a reason? Now that you have eternal life, what's the use of keeping you? Go! Don't bother me! ”

Wukong just kowtowed: "I was wrong...... Ancestor, I was wrong! ”

Chen Ang waved his sleeves, drove it away, went straight to the room, and closed the door to say goodbye.
