On a crisp autumn day, the night sky is full of stars.

Liang Feng, the winner of the Phips Prize, the highest award for mathematical achievement, and the father of the epoch-making artificial intelligence system 'Tengu System' in the solar system, looked up at a second-magnitude star in the direction of ten o'clock in the south, frowned, and had a trace of worry in his heart - not long ago, the Orion Observatory using the artificial intelligence system 'Tengu 2' sent a message that in that star field, 'Tengu 2' once again discovered a high-level intelligent civilization, and the star system where the civilization is located is relatively peculiar, which is a three-body star composed of stars of different sizes.

"The environment of that three-body civilization is far inferior to the earth, will they invade the earth?" he asked himself in his heart.

"Dr. Liang, the leader and chief scientist of the solar system's artificial intelligence system 'Tengu System'?!damn it!" A voice sounded abruptly.

Liang Feng was shocked, and saw a tiny but extremely transparent extremely round water droplet floating in the air, and exclaimed: "Slow, slow! Let me die clearly! You are the 'water droplet' of the three-body people? Why do you want to kill me?"

"Exactly. Because of your 'Tengu System', you humans discovered our Trisolarans two hundred and fifty years in advance, so, as a mathematician and artificial intelligence expert at the pinnacle of the solar system, you must die!" replied Shui Di.

A bright light flashed, and Liang Feng slowly fell, and then he seemed to hear the alarm: "Water droplets found! Water droplets found...... The alarm sound was issued by the intelligent early warning system of the whole solar system network......

——

In the middle of the night, lightning and thunder roared, and heavy rain poured in.

On a small hill, a group of black shadows dressed as miners were hidden in the shrubs of full height, all of them looking anxious and drenched in water.

"CNM! Cheng old man, uncle, I CNM, CNNN, your eighteenth generation ancestor!" said a voice that tried to keep his voice down, but was still rough.

A shriveled voice said: "Black dog, if you can break the formation by fucking my eighteenth-generation ancestors, you can fuck me casually, fuck my thirty-sixth-generation ancestors!"

"Old man Cheng, you have been saying that the Mine Protection Array has not changed for a few years, and it has been verified several times, why-why is it that now, you can't break it?"

"We can't break the formation, we can't escape, we all have to die, we all have to die!"

"It's all going to be hung on the flagpole and fed to the ghost-faced vultures!"

Everyone was gossiping, all of them were anxious and abnormal, and their tone was bad.

Old man Cheng said, "Little old man...... Xiao Lao'er doesn't know how the magic circle of this spirit stone mine can be changed! Liang Feng, you also verified it yesterday, it's the 'Four Elephants Mixed Yuan Array', right? ”

Liang Feng nodded and said, "Yes, I verified it yesterday, and it is indeed still the 'Four Elephants Mixed Yuan Array'." "Among their group of escaped Lingshi mine miners, only Old Man Cheng and Liang Feng knew the magic circle, and Liang Feng's knowledge of the magic circle was still taught by Old Man Cheng.

"What should I do now? Tell me about it! In order to break the formation, our dozen brothers listened to you two for everything, and now you two let so many of our brothers accompany you two to wait for death here?" Everyone gathered in front of Old Man Cheng and Liang Feng, their faces hideous.

Old man Cheng drooped his head, the rain and tears on his face poured down together, and he cried out: "Little old man...... I don't know, little old man!"

Liang Feng had been observing the light curtain of the magic circle not far away, and a lightning bolt slashed on the light curtain above the magic circle, and the light curtain rippled for a while, and then returned to its original state. He felt the sound of their rapid breathing in front of him, and saw several pairs of blood-red eyes close at hand, and hurriedly said, "I have a way!"

Everyone was shocked and said, "Say it quickly!"

Liang Feng said: "I guess this is the 'Liuhe Qingsha Array'." Zhao Yiqian two, you two take twenty steps to the east, Sun San and Li Si, you two take twenty steps to the west, and the rest of the people wait forward, wait for my whistle to sound, and you will hit the light curtain together. Remember, be sure to strike in unison after the whistle blows five!"

Everyone glanced at Liang Feng and said, "Okay! I hope this is the last test attack!" They quickly took their places.

After the blow, the crowd gathered around and said, "How?"

Liang Feng closed his eyes slightly, replayed the rippling situation of the light curtain just now in his mind, and said secretly: "This broken array is like solving an equation, and the 'four-elephant mixed element array' is a quaternary one-dimensional equation, usually only four equations are needed to solve the value of each element, and the array can be broken." However, the 'Liuhe Qingsha Array' is much more complicated than the 'Four-Elephant Mixed Element Array', and it may be an eight-element one-time equation, or it may be a ten-element equation, and it takes at least ten equations to solve the value of each element, and it is now impossible to solve the value of all the elements! But if certain conditions are met, it is also possible to solve the value of one of the elements. ”

"Hmm...... When the lightning struck the light curtain there just now, the light curtain rippled like this, and when each of them attacked with two weak and one strong just now, the light curtain rippled like this...... "He was immersed in the rigorous contemplation of 'mathematics'—oh no, this world is called 'embellishment'—reasoning.

Everyone looked hopeful and restless.

After a long time, Liang Feng opened his eyes and said in a deep voice: "Fourteen steps to the left, three people; Eight steps from the left, two people; Eight steps to the left, four people, four steps to the right, one person, listen to my orders, and strike with all your strength at the same time, you will definitely be able to break a hole in the light curtain!" He couldn't break all the circles, only a small corner of the circle.

The crowd acted quickly as he commanded.

With a low 'click' sound, there was a violent ripple on the light curtain of the front array, and a large circular hole with a radius of one foot appeared.

Liang Feng shouted in a low voice, "Hurry, hurry, rush out! That hole will be restored soon!" ......

——

Liang Feng activated a mask he had drawn and curled up on a fork of a tree under the cover of dense foliage, which seemed to merge with the branches, which grew on the edge of a cliff with a deep stream below.

He didn't move, but his thoughts were myriad—"I don't know where they fled to?" I didn't flee with them, but hid not far from the spirit stone mine, is it right?...... Alas, his own cultivation is the worst, and escaping with them will definitely be the last, and he will be the first to die. Besides, the one in the Peiyuan period can't fly with a weapon, how can he escape the pursuit of the deacon in the mine, even the one who escapes the farthest, and it is estimated that there is no hope of escaping. ”

"The Mine Protection Array has always been the 'Four Elephants Mixed Yuan Array', and everyone has made full preparations for breaking the formation, but half an hour ago, when the formation was really broken, it was found that it was not the 'Four Elephants Mixed Yuan Array', but the 'Liuhe Green Demon Array'?!"

"If it weren't for the old man Youcheng's four years of careful formation teaching, his formation principle is quite thorough, if it weren't for the fact that he awakened part of the memories of his previous life more than a year ago, and had a peak-level mathematics-oh no-embellishment attainment, how could he re-deduce the formation changes in a few breaths, and finally break a small corner of the 'Liuhe Qingsha Array'?"

"It's just a small corner, and everyone escapes, but a lot of time has been wasted, and it has also alarmed the deacons in the mine, right?"

As soon as Liang Feng turned his gaze, he saw a red light rising from the spirit stone mining area and sweeping eastward, "The deacon of the Dao Initiation Stage has chased him out with a flying magic weapon!"

"Ahh

He was soaking wet, and the rain poured down his neck, down his back, and down his trousers to the branches. His back was getting colder and colder, "The voice was like that of a thin monkey, he ran the fastest, but he was the first to die?......"

"Ahh

"Lao Hei, Lao Wang, Lao Zheng...... They were all killed?...... Eleven...... Twelve...... A baker's dozen...... There were thirteen screams, and—and the ...... who died quietly."

In the distance, another scream was heard, "There are not many people left now?...... The red light came in his direction...... Are you going to die?......"

"In my previous life, I stood at the pinnacle of the world in a certain field, but in this world where everyone can cultivate the truth, I was killed as a lowly miner, silently......"

"Master, you sold me here as a slave miner, presumably to let me die here!"

"Senior sister, now you must not dislike me as an eyesore, right? You must have married into the Changhu Gang as you wished and became the wife of the young gang leader, right?"

Thinking of his former junior sister, the junior sister who used to stand under the peach blossom tree and sweetly called him 'senior brother', Liang Feng's palms became tighter and tighter, and his nails pierced into the palms of his hands, which hurt very much, but there was a painful pleasure in his heart.

He looked at the red light that was getting closer and closer, and the fear in his heart suddenly disappeared, and he felt that death was not so terrible-

The red light gradually became clear, turning into a long, flat flying magic weapon, a wind boat, on which stood a monk, and the robes were blown by the wind to hunt. The monk's gaze swept over the lush tree on the edge of the cliff and exclaimed, "What demon beast?" A huge spiritual power wooden spear shot towards the canopy.

There was a scream of a black spirit marten, a few branches breaking, and several large branches falling into the deep stream below the cliff.

The monk heard the cry of the black spirit marten, and without looking back, the boat flew away.

——

Liang Feng woke up slowly, and saw a beast face close at hand—the face of a little fox, and the little fox was holding a spirit fruit and was about to stuff it into his mouth—the two pairs of eyes stared at each other for a moment, and the little fox screamed, dropped the spirit fruit and fled quickly.

Liang Feng propped himself up, watched the little fox disappear into the dense forest by the river beach, and said softly: "Thank you! Thank you!" He picked up the spirit fruit on the ground, wiped off the sand, and ate it - the spirit fruit was sweet and juicy in the mouth, and it seemed to be full of spiritual power, and after a few bites, the chest that had been hit by the heavy blow seemed to be less painful.

"The double-array concealment talisman drawn by himself can really hide the two-grade cultivation! Before the spiritual power wooden spear hit him, the black spirit marten cry in disguise really deceived the deacon of the initiation period! He was still hiding behind the branches, but even so, with a casual attack from the monk of the initiation period, he was still seriously injured and fell into the stream below. Fortunately, it has rained heavily in the past few days, and the stream is abundant, otherwise I didn't get killed and fell to my death......"

"Since I don't die, uncle, then, junior sister, master, we will meet again......"

He finished eating the spirit fruit in a few bites, and then lay down on the river beach and rested for a long time before standing up, and looked in the direction of the east for a long time-if he wanted to become stronger, he had to go to Dongqi City! He limped forward step by step......
