Where is my home? The mountains and rivers are still there, the city is broken, and the people are dead.

How could a general leave the battlefield after a hundred battles? Qin Song returned to the city, he looked at the exiled people, drew out his spear and held it in his hand. His hands burst with bruised tendons, and his face was bloodied.

"Master Hou, Lao Qin is here, hold on. ”

Young and lonely, Qin Song's life was given by Master Hou. From the moment he was saved by Zhou Yi on the battlefield, Qin Song swore that it was his life's duty to protect his family and defend the country, and it was his duty to protect the Hou Ye. His spear had to be stained with enemy blood before he could stop breathing.

"Driving ......"

In Yejiang City, the flames of war continued, and the fire that ignited was like a hideous dragon roaring on the bank of the Yanyun River.

The clouds are pressing the sky, and the flag is swaggering.

Qin Song was riding on horseback, and suddenly heard a strange bell, flickering far and near, like the sound of the tide crashing on the shore. Qin Song gradually lost his will and fell from his horse to the ground. He held his head in his hands, gasped for breath, and suddenly felt dark in front of him, unconscious.

Where the two armies faced each other, the wind was fierce. Zhou Yi used a nine-section sword in his hand, his eyes were fierce, the sword light turned into dragon qi, and he flew down from the city and killed it.

"This old thief is unfathomable in cultivation. The two of us went up together and beheaded him. Hei Impermanence said with a solemn expression.

The three of them clashed, like the tip of a needle against Maimang.

Rumble......

In this area, the spiritual energy turned into a tidal wave, forming a huge energy fluctuation. A mortal soldier was mortally wounded and killed. Zhou Yi's hair was arrogant, and the whole person was not angry but mighty, like a killing god who came out of hell, Yama.

The power of the Nine Dragons Sword Technique was so strong that it had already resounded in the Eastern Earth Cultivation Realm, and few people dared to beat its edge. This is a kind of killing holy art, and the sword is the king of a hundred soldiers. It is not an exaggeration to say that the supreme sword immortal can cut the moon with one sword, and the mountains and rivers can be broken with one sword.

Kendo is a pure art of killing. The Nine Dragons Sword Technique is the art of the Taiyi Sword Sect, a technique of inheritance, and its power is naturally extraordinary.

Although Zhou Yi has not obtained the true biography, he is strong enough.

Sword drawn, nine true dragons like tigers out of the mountain. Next to Zhou Yi, the aura gathered, and it turned into a dragon. The nine-section sword in his hand turned into nine long swords, surrounding him. Each sword is the size of an ordinary person, flashing with endless murderous aura, making people unable to open their eyes.

Zhou Yi made a move, and it was with a killing heart, with supreme swordsmanship, and the Nine Dragons Sword Technique.

Black and white impermanence knew that they were still underestimating the enemy, even though Zhou Yi was just an ordinary disciple of the Taiyi Sword Sect, but he had lived long enough. Moreover, in the human world, he fought and killed, which made his swordsmanship wash away the dust and be improved.

Nine divine swords, each of which is like an evil dragon, black and white impermanence seems to see the scene of a mountain of corpses and a sea of blood from it.

The two didn't dare to keep it, and each urged the secret method. Black and white impermanence chanted the mantra, and suddenly there was a buzzing sound.

"...... Uproar"

Countless jackdaws suddenly appeared. Densely packed like locusts, they appeared above the sky of the Southern Yan army.

"Old thief Zhou, have you heard of the poisonous crows of our Divine Crow Gate? Black and white impermanence said coldly.

Zhou Yi looked at the jackdaw that appeared in the sky, and his eyes jumped. He remembered that he had heard of the secret news in the Shimen before, that there was a sect called the Divine Crow Sect that specialized in raising spirit beasts in the Eastern Earth Blood Luo Valley. This sect not only keeps spirit beasts and spirit birds in captivity, but also is good at using poisonous demon beasts to fight. This sect is called the Divine Crow Gate, and it is rumored that the people of this sect raise a kind of demon beast that is only available in the Blood Luo Valley, called the Jackdaw.

Zhou Yi looked coldly, each of these jackdaws was the size of an ordinary chicken and duck, but they all exuded a trace of imperceptible spiritual power fluctuations.

Zhou Yi knew that these jackdaws should definitely not be underestimated. Such a poisonous crow, one, two combat capabilities are very low, but if they appear in groups, the power is unimaginable. Devouring gold and devouring silver, nothing is broken, and no grass grows where it passes.

Zhou Yi concentrated on urging the immortal sword, and an extremely powerful cultivation force emanated from his body.

The sword is like a real dragon, and the spiritual power is like an ocean. Countless jackdaws covered the full moon in the sky, and even pressed on the city sky, like black clouds pressing down on the sky.

The Nine Dragons Sword Technique is just to the yang, just like the waves of the Yangtze River and the flame of the bright sun.

As soon as the countless poisonous crows touched it, they were shattered by the sword light and turned into powder. Zhou Yi did not retreat but advanced, and the whole person was surrounded by sword qi, like a scorching sun god Buddha rushing into the group of poisonous crows. He held a strange-looking nine-section sword in his hand, like a long dragon running to the moon.

"What an old fellow, even a poisonous crow can't help you. However, the two of us are not easy to bully. It was not surprising that he resisted the flock of jackdaws and rushed towards him. The two of them pinched their fingers, and the spiritual power of the little bell rose, and the sound coming out of it became a little louder.

Zhou Yi originally felt that the bell was extremely strange and confusing. He originally rushed over to kill, just a plan to secretly cross Chen Cang. Obviously trying to catch black and white impermanence, but actually trying to destroy this clock. Otherwise, even if he has the power to reach the heavens, although he has the power to protect himself, these mortal soldiers around him will suffer. But now the bell was a little louder, making him feel the spiritual power in his body stagnate. Zhou Yi took strong action to suppress the bell with strong cultivation, and made up his mind in his heart that even if the cultivation of the fight was damaged, he would kill the two demons on the opposite side.

Zhou Yi held the sword in his right hand, and an illusory dragon shadow flickered. The blood above his head was soaring, and a real dragon appeared.

"Boom ......"

Hundreds of poisonous crows were shocked by this force, and the black and white impermanence took a move from Zhou Yi, and their bodies were shaky. The two fell to the ground, snorting, blood already flowing from the corners of their mouths.

The judgment was made, and Zhou Yi pointed at the two of them with a fairy sword in his hand. One person alone has no fear of tens of thousands of troops in Nanyan.

"Thief, take your life!" Zhou Yi raised his sword and was about to see blood.

The cold wind was cold, and the black and white impermanence laughed.

"You old thief, if you have the ability, you will kill the two of us. The consequence is that the entire Yejiang City will be buried for us, and we will only have to die, and these mortals will not be able to live if they are poisoned by us. ”

Zhou Yi followed the black and white impermanence gaze, and sure enough, he saw everyone in Yejiang City hugging their heads and wailing, and there were countless jackdaws hovering in the sky.

Zhou Yi's eyes flickered, he sighed heavily, and put down the nine-section sword in his hand.

"Let go of the people in the city, and the old man will go with you. ”

Black and white impermanence stood up, looked at Zhou Yi with a faint gaze, and said nothing.

Zhou Yi could see what they were thinking, and he didn't see any action from him. A flash of light appeared and wrapped around him. He moved his spiritual power with his palm, slapped it his chest, and spat out a mouthful of blood from his mouth.

The battle armor on his body was stained with blood, Zhou Yi almost fell, he opened his eyes and said: "The old man seals the whole body cultivation, and please don't hurt these people...... word by word, Zhou Yi said bitterly.

Black and white impermanence laughed, and his divine sense swept over Zhou Yi. Seeing that he had indeed sealed Xiuwei, a trace of killing intent flashed in Hei Wuchang's eyes, and he pinched Zhou Yi a little, and took out the immortal rope and tied it to this person.

"The Taiyi Sword Sect really lives up to its reputation, but Zhou Daoyou ...... Those who know the times are Junjie, the general trend of the world, after all, is still in Nanyan. ”

Bai Wuchang couldn't help but sneer: "Old thief, my two brothers have already made a promise to King Liang to present your head. Death at our hands will not be in vain in your name. I'll let the whole Yejiang City bury you later, haha......"

Black and white impermanence laughter is like a devil, and Zhou Yi scolded angrily. The two of them no longer bothered with a prisoner under the stairs, and countless jackdaws poured into Yejiang City like locusts. At this moment, the wails resounded throughout the world, and countless people were devoured by poisonous crows.

"Ah......h

Zhou Yi suddenly exerted his strength, and there was a divine glow blooming on his body. Streams of spiritual power are like floods surging from a broken embankment. Zhou Yi shattered the immortal rope on his body, his hair was messy, his eyes were red, he held the nine-section immortal sword in his hand, and his eyes were full of evil and looked at black and white impermanence.

"Shameless thief, the old man will definitely want you two to fall. ”

Black and white impermanence was taken aback, he never expected Zhou Yi's cultivation to be so deep. Seeing that he was like a killing god returning from hell, both of them shuddered.

"Let's go!"

Both of them turned into a burst of aura, and their figures disappeared in place.

Countless jackdaws were like a flood to bite Zhou Yi, and Zhou Yi stabbed the poisonous crows in his hand and rushed out of a bloody path. Whether it was the sergeant of Nanyan or the jackdaw of Blood Luo Valley, they were all on fire and incinerated into ashes.

He was extremely fast and flew into the sky. Bai Wuchang's body was slow, and he was caught up by Zhou Yi.

The supreme sword is like a thousand exploding planets.

Bai Wuchang gritted his teeth and said: "Big brother, you go first, I will drag him, you must avenge me and destroy Beiyan." ”

Hei Wuchang watched his younger brother being wrapped in Zhou Yi's sword light, and let out a miserable scream. He gritted his teeth fiercely, but he no longer hesitated, chanted the trick in his mouth, spurted out a mouthful of essence blood, and his speed increased a lot again.

Zhou Yi raised his head and shouted, the dragon shadow was vertical and horizontal, the sword qi was flying in the sky, he cut off Bai Impermanence's head with a sword, and there was a monstrous blood shadow in his eyes, chasing after Black Impermanence.

Outside Yejiang City, in a deep valley.

"The general is awake?"

Qin Song shook his head, he felt his head dizzy, and his eyes were full of stars. Qin Song froze his mind, looked intently, and saw that the person talking to him was a white-haired old man, who was sitting next to a waterhole fishing at the moment.

"You saved me, dare to ask the seniors how Ye Jiangcheng is now?" Qin Song saluted and said.

"General, Ye Jiangcheng has been broken. The old man put down the fishing rod, looked at Qin Song and sighed slightly.

"How could it be? Hou Ye has great powers, can't he guard Ye Jiang?" Qin Song staggered and almost fell. He leaned against the wooden pillar of the rain pavilion, and only felt that the sky was spinning.

"Although Hou Ye's cultivation is strong, there are also cultivators on Nanyan's side. General, the world has changed greatly, and the three-legged stand is just beginning. ”

"Who are you, why did you save me, what happened to Hou Ye?" Qin Song roared.

"The old man is just a mortal man, the general doesn't have to worry, I won't hurt you. In that day's battle, both sides suffered damage, but Hou Ye's cultivation was profound, and there must be no danger. For the sake of today's plan, the general still has to think about how to resist the Nanyan army. The old man said in a deep voice.

"I want to go back to Beijing and ask the emperor to send reinforcements. There is no room for loss on the frontier, and the people are even more innocent. Qin Song said in despair.

"If the general wants to go back to Chang'an, how can he get there? ”

After the white-haired old man finished speaking, a cloud appeared. He grabbed Qin Song with his hand, and the two of them turned into a burst of spiritual light and disappeared in place.

In autumn, before the sun warms the world, the air is already cooled by some rain.

At the entrance of a small courtyard, an osmanthus flower is fragrant, which makes people feel beautiful.

"Hey, I'm so worried, this kid!" a middle-aged man in a linen cloth robe knocked on the wooden door of the courtyard.

"Brother Zhang, what's wrong?" opened the door by a young man with short hair and wearing a green coat.

"It's not my rabbit cub, I heard that their husband assigned a problem. This little rabbit kept pulling me and asking me, "What am I going to do?" ”

After hearing this, the short-haired man's eyes lit up, as if he was interested. "What did they ask? But, Brother Zhang, why did you come to me instead?"

The middle-aged man was not afraid of his laughter, and said with a smile: "No, I guess that the cub in my family told you what happened last time." ”

It turns out that a few days ago, a little child who lived next door to him encountered a problem in a private school, and he happened to help solve it.

The topic is as follows: Suppose there are 100 people in the private school, a total of 100 books, one for three students, and three books for each teacher, ask the students, how many people are in each of them?

It is not difficult to solve this problem, but it is difficult to find a simplest algorithm. The short-haired man happened to encounter this matter that day, and solved this problem easily, it seems that his algorithm attracted the attention of Mr. Private School!

"What's the topic today?" said the short-haired man, who also wanted to see what the interesting private school teacher was going to do.

"Hey...... Why don't you go over and ask that kid of mine yourself? How can I remember any subject, I will farm. The middle-aged man said this, stretched out his calloused hand and scratched his head.

"Sir, I'll help you bring the field tools, and I'll trouble you more about my rabbit cubs. The middle-aged man said with a smile.

The short-haired man knows that this simple man who has been plowing the fields for half his life is all for his son's future, but this is also too doting. These two words of learning are not taken from the hands of others, but must be learned, thought and acted on by oneself. However, he knew this, and he was afraid that it would be difficult for him to convince himself, so he did not speak.

Now the emperor of the Great Qin State has promulgated a land law to encourage the cultivation of fertile land, and there are even rewards. Therefore, now every household is digging in the wilderness. Since the middle-aged man bothered him to teach his homework, he agreed to help the short-haired man clear the wasteland. This time and again, it can be regarded as a return of favors.

The short-haired man had just pushed open the bamboo door, and there was a burst of chickens and dogs barking.

"Uncle, you help me catch that chicken. If my father came back and saw the chickens running away, he would have scolded me to death. "A boy of seven or eight years old in the yard was chasing a rooster flying around.

The short-haired man shook his head and glanced at it, and his body moved, and the whole person jumped up.

"Wow, that's amazing!Uncle, do you know martial arts?" the boy clapped and screamed when he saw that the short-haired man easily grabbed the rooster running around.

"At a young age, you can't learn anything!" said the short-haired man, ignoring the boy, and instead said with a straight face. He has always hated naughty children, and he has no interest in reading questions at the moment.

Seeing that he was leaving, the little boy hurriedly trotted over and wrapped around the arm of the short-haired man, and said flatteringly: "Uncle, I told Mr. the algorithm you taught me that day, and she praised me." ”

The short-haired man snorted coldly, "So, I've given you another question, right?"

"Yes, but I can't solve this problem the way you told me. This gentleman, it's really getting stricter. The boy said helplessly.

The short-haired man was surprised that he couldn't even solve the equation he gave for what the private school teacher had done. His kind of algorithm is unique in this world, and it is enough to deal with many problems.

"Tell me, what's the title? What's going on with the chickens and dogs jumping all over the yard?" said the short-haired man angrily.

"It's not because of my husband's question, I really can't help it. The boy said with a sad face.

"The gentleman said, "There are black, white and gray chickens, each gray chicken lays five eggs a day, the white chicken lays three eggs a day, the black chicken lays only one egg a day, and today there are a hundred eggs, how many chickens are there in black and gray and white?" The little boy took a branch and drew on the ground.

After hearing this, the short-haired man smiled slightly. It turned out that the kid made the chickens fly and the dogs jumped, and he painted the chickens at home to solve the problem.

"If you do that, you won't be able to solve the problem. You have lost the paint, and after I have explained it to you, you will help me to pass on a letter to your husband, and you will come to my lodgings in the evening to get it. Don't worry about your husband scolding you for this, he'll understand after reading it. The short-haired man said seriously.

The boy nodded, and looked at the short-haired man again. Sure enough, the uncle drew some strange symbols on the ground that he had told him about last time.

"Remember the method I told you last time, the first symbol represents the black chicken, the second is the white chicken, and the last one is the gray chicken. You see, we can list two equations according to this problem. The sum of the number of gray, white and black chickens is equal to 100, and the number of eggs laid by the three colors of chickens per day is multiplied by the corresponding symbol, and then the sum of the three is also equal to 100. The short-haired man preached as he painted.

In fact, this question is not difficult, the symbol represented by the black rooster must be an integer of three, so it can be listed in an exhaustive way. But at the moment, the short-haired man doesn't plan to use this brute force to solve the problem.

Although the short-haired man knew how to parse the indefinite equation composed of these two equations and three unknown quantities, it still took a long time to communicate clearly with the boy.

The problem starts with the elimination of one of the three unknowns, and after the two original equations have eliminated one of the variables, it is much easier to leave two variables. Then take the new variable to solve the fraction in the equation, narrow down the range of variables, and then get the answer.

"There are several answers to this question, and it doesn't matter if you don't understand it. If your husband asks, you will say that you have calculated it by exhaustive means. Remember what I said, and come in the evening to pick up the letters. The short-haired man touched the boy's hair and smiled.
