Chapter 4 Olympiad Mathematics

After going back, Zifeng took medicine on time and quickly recovered his health, even better than before. Pen, fun, pavilion www. biquge。 info Zilei was particularly interested in this medicine, and made a detailed analysis of the rest of the medicine, but he didn't understand it, and even wanted to go into the mountains to learn from the old man. Zifeng has always been obsessed with the old man's qigong, and Shaolin Temple also has qigong, but there is very little actual qigong, otherwise he would not suffer such a big loss.

In the year of study in school, the four of them have caught up with their own diligence and hard work, and the four of them still have a focus on various subjects. Zifeng likes physics, especially quantum physics and spatial dimensions. Ziyu has a little insight into literature, history, archaeology, and paleography. In his spare time, Zilei enjoys music, but has a strong interest in chemistry and Chinese medicine. Although Zidian is stunned, he is a mathematical and computer genius, and through computer assistance, he can easily calculate mathematical models.

The quadrennial International Mathematics Olympiad is about to kick off, and after layers of selection, the remaining six people from Songshan Middle School were sent to the United States to participate in the finals, in addition to the four brothers, Lin Ling and Ouyang Yunfang from the first class of high school. For Ouyang Yunfang, the four of them are no strangers, and they have had contacts in the Olympiad class. Ouyang Yunfang, nicknamed Black Pearl, was named because of her dark skin but delicate face. It's refreshing, and I heard that I've learned kung fu, but who hasn't seen it. Unlike the four brothers, due to the distance from home, Ouyang Yunfang lives in the school, and can often be seen in self-study at night. This Ouyang Yunfang is relatively withdrawn, and he usually doesn't have many friends, but he is very good at mathematics, although he is only in high school, he is already proficient in calculus and probability statistics, and he is quite admired by Zidian. The two worked together to solve many problems and can be called the main force of this competition.

Chapter 5 The Water Ghost of the Luo River

The city of Luoyang in September is so hot that people can't breathe, and the Luohe River, which is not far from Luoyang City, is a good place to swim and bathe, and the four brothers are no exception. Every weekend, the four brothers come to the river to bathe and play. The best among the four people is Ziyu, for Ziyu, the water is like at home, at ease, with ease, the master also teaches according to his aptitude, and deliberately taught Ziyu the unique and unique closed qigong of Shaolin Temple, which can not only make people breathe under water, breathe normally, but also attack with water flow, cooperate with other Shaolin kung fu, and can also dominate one side underwater.

I often come to the river to swim, and naturally I have made a lot of friends, Haisheng is one of them, Haisheng is sixteen or seventeen years old, not tall, loves to talk and laugh, mixes with Ziyu every day, and also learns some underwater skills, and the water nature is naturally good.

One Sunday afternoon, Hai Sheng and his four brothers made an appointment to swim again, and this time a big sign was erected by the river, which read, "The water depth is dangerous, swimming is prohibited."

After seeing it, Zifeng said with a smile, "It's not like swimming once or twice, why did you suddenly put up a sign today."

"Don't you know, it's all said on TV that Luohe drowned someone a while ago", Hai Sheng said seriously.

Zidian couldn't help but interject and said, "What's so strange about this, don't there be drowns every year."

Haisheng pouted, "Yes, but it seems to be a bit much this year, and I heard that drowned are all swimmers."

Ziyu was impatient, "Come on, if you don't dare to go down, forget it, I'm too hot" After speaking, a fierce man stabbed down. When you are done, you will wave to the riverbank and beckon everyone to come down.

Towards evening, it was just dark, and the four brothers went ashore after swimming and planned to go back to eat. Haisheng still felt that it was not enjoyable, and said to Ziyu, "I'm swimming around, you guys go back first", after speaking, with a plop, a fierce man stabbed down and disappeared.

"It's not fun" Ziyu said while wiping the water on his body, the four of them didn't care, it was like this in the past, after wiping it dry, the four of them were about to leave, Ziyu suddenly felt that something was not right, why didn't he come out to ventilate after more than ten minutes of this Haisheng fierce son, this kung fu is stronger than me.

"No, big brother, Haisheng is drowning, hurry back to save people", after speaking, he turned his head and ran back. The shore was overgrown with weeds, and looking into the river, I could see a whirlpool, flickering and flickering, different from usual. The four brothers took off their half-sleeved shirts while running, and jumped off before they had time to drag off their shorts, and Ziyu bore the brunt.

While swimming, Ziyu also pondered in his heart, Haisheng has been swimming for a day or two, although it is not as good as himself, the water is not bad, so he didn't come up for a long time, is it entangled by aquatic plants? Approaching the whirlpool, Ziyu plunged his head down, opened his eyes, although there are many underwater aquatic plants, but it has not yet reached the point of entanglement. As evening approached, the visibility under the water was very low, and there was a figure writhing and struggling in front of him, it must have been Haisheng, his feet were like something holding back and breaking free. When he looked closer, Ziyu was scared into a cold sweat, and it was a big hand that tightly grabbed Haisheng's feet and neck. Below was a black monster, with a head but covered with pimples, like the back of a toad, and the eyes that looked like lizards bulging outward, and the legs were bent to see clearly, and the monster was pulling Haisheng down.

Those who don't know are fearless, Ziyu can't care about being afraid, and uses his hand to buckle the monster's hand, but this hand is very slippery, and he can't buckle it at all, the monster turned his head to look at Ziyu, Ziyu is not ambiguous, a water slap hit the monster's eyes, the monster let go of Haisheng, and reached out to grab Ziyu. Haisheng took this opportunity to swim back quickly. The monster followed like a water snake, Ziyu secretly thought, this guy's body is slippery, and he can't use his strength in the water, so he is definitely not an opponent, but this guy has legs that means that it is not a species in the water, and if he runs, it may not be my opponent. When the brother and son saw it, they turned around and ran, playing to their deaths. Seeing that the monster was getting closer and closer, he could almost reach Ziyu's feet, Ziyu was anxious about this guy, Ziyu thought, I have eight ways to escape and I'm afraid you won't make it, I forgot to take off my shorts when I thought of diving, and I thought of a trick Golden Cicada to get out of my shell, so I untied my trouser belt, luckily dantian, my legs were forced, I kicked and kicked, and a force burst out from my belly, carrying shorts, like a bazooka, along my two legs, and launched straight out. It's not biased, the shorts are hitting the monster's face, and I don't know if this monster has intelligence, it was instantly messy. Ziyu lost his shorts and loaches and swam out a long way.

Five people crawled ashore with rolling belts, dressed in rough clothes. Fortunately, the monster didn't follow, and at this moment, Haisheng's face was pale, and there were scratches on his legs.

"Back. Go home.... It's terrible".

Zifeng looked at Haisheng and asked

"What the hell is going on, what's that thing in the water?"

Ziyu wiped the water on his face with a towel, gasped and said:

"Or I'm going to say it, I... When I went down, I saw that I was still being dragged by the feet of a monster, and the monster was as tall as a man, and its eyes were as bright as brass bells, and it was so black that I couldn't see any color, and it was slippery, and I didn't know what it was.

At this moment, Zifeng, Zilei, and Zidian were all stunned.

"You read that right, I'm an atheist," Zidian shouted.

"He was right, I swam to the middle of the water, I felt something grabbed my feet, I started to think it was a water weed, but the claws were very tight and couldn't break away, I dived under the water to see clearly, my mother, is a monster I have never seen before, the head is a bit like a toad, the eyes are huge, I struggled to swim up, it dragged me down, is stalemate, fortunately Ziyu came. At this moment, Haisheng has come to his senses.

"Why don't we go to the river and have a look," Zifeng was a little unconvinced.

"Go ahead, I didn't believe in ghosts before, but today I believe in them", after speaking, Haisheng climbed onto the road on the shore and walked away without looking back.

"Water ghosts are indeed recorded in ancient times, I don't think there is a supernatural element, I suspect that it is a variant or mutation of some kind of animal, or it may be an alien creature. Ziyu said.

"Let's go back first, in case that thing isn't in the water, we can't hang it all up", in the night, three wet and a person with a towel around their lower bodies hurriedly walked back on the road.

Back at the residence, the four of them had a heated discussion, checked all kinds of ancient books, and there were many records about water ghosts, and there were different opinions, but most of them had supernatural elements, which were difficult to explain with science.

For the next month, the four of them went to the river to see it, but they never saw the monster again, and even they wondered if they were mistaken, and thought the seaweed was a monster.
