Chapter 13: Pythagorean Triangle

"What do you want?" said the old man with a kind smile.

Qin Yu withdrew his hand and hesitated: "I almost forgot, Bai Rou'er said that only she can uncover this Zhenlong talisman, as if ...... She must have sealed it. ”

The corner of the old man's mouth wiped a trace of evil smile, stroked his beard and said: "As far as the old man knows, who owns this Zhenlong talisman, who can reveal it, "Dayu Seeking the Dragon Formula" is currently owned by you, therefore, only you can unveil it, yes or no?"

"I don't really know, I'd better wait for Bai Rou'er to come back. Qin Yu lit a cigarette, snorted, and looked in the direction of the subway station, where it was pitch black, and there was no trace of white meat.

The old man tapped the manhole cover three times with his crutch and sneered: "It's good, it's good......"

After that, the old man seemed to sit on the railroad track next to him with great effort, and Soho went up to help the old man out of kindness, and when the old man sat down, Soho let go of his hand and found that his palms were stained with sweat, stained with a lot of colorless and transparent liquid, slightly viscous, but Soho didn't care, thinking that it was because of the dampness of the underground space.

Qin Yu took two puffs of cigarette, he was thinking, if this old man was pretending to be "Bi Long Wen", he should not be able to uncover the Zhenlong Talisman by himself, otherwise he would have done it earlier, it is estimated that Qin Yu would have to be needed, or Bai Rou'er, to uncover the Zhenlong Talisman, as long as he does not uncover the talisman and does not let the old dragon come out, when the real Bi Longwen arrives, it will definitely be easy to subdue the old dragon, after all, he is a professional in the heavenly court.

So, don't panic, as long as Qin Yu doesn't pick up the talisman, just wait for Bai Rou'er and Bi Longwen to come back.

Thinking of this, Qin Yu put his mind at ease, took out a cigarette, and prepared to talk to this strange old man.

Just about to offer a cigarette to open his mouth, Qin Yu suddenly heard the sound of whistling under the lock dragon well, and the sound was even more terrifying this time, like an underground tsunami, carrying thousands of troops and horses, swept in, and the entire tunnel was shaken, and the howling sound was felt at the wellhead, and the two high water columns rushed up to the sky again, but because of the Zhenlong Fu, the manhole cover was still very tightly closed.

"Not good!" The old man suddenly shouted, pounced on the manhole cover, and used his rickety body to hold it down, and then turned his head and shouted at Qin Yu anxiously, "Come and help, you can't hold it down!"

Qin Yu and Soho subconsciously pounced, the manhole cover was big enough, the three of them avoided the water spray hole (ultra-high pressure, spraying will hurt), one pressed a corner, the manhole cover was stable, but Qin Yu felt that there was no upward power under his body, and he felt strange, the old man seemed to be unable to suppress it, his body rose and fell twice, and he quickly shouted three words: "Thousand catties falling!"

The sound is like a bell, deafening!

After shouting, the old man's body evolved into the form of an old king, lying firmly on the manhole cover, and shouted at Qin Yu: "Quickly uncover the Zhenlong talisman, otherwise the three of you and I will die here!"

Qin Yu was a little confused, at this time, the water column rose to the sky again, Soho was closer to the air hole, the water rushed on her clothes, and her coat and jacket were completely taken off, and the water column was pressed against the cave wall, Soho only wore a small suspender, and the clothes were washed off by the water, and the flowers were discolored, and he wanted to reach out to cover the vital parts, the old man scolded: "Don't move! Qin Yu! The Zhenlong Fu can no longer resist the demonic energy under the well, you quickly remove it, and replace it with the old man's Pythagorean triangle array!

Qin Yu was even more confused, is the Pythagorean triangle array? Is it the Pythagorean theorem?

"Hurry!" the old man urged, Qin Yu had no idea, so he had to do it, his left hand clasped the edge of the manhole cover, and his right hand reached over and removed the Zhenlong talisman.

"Throw it aside," said the old man again, "and the old man is going to do it!"

Qin Yu threw the Zhenlong Fu into the railroad tracks, looked back at the old man, and wanted to see how he did it, clinker, the old man actually got up from the manhole cover, picked up the crutches, and said with a sly smile: "Hehe, Qin Yu, you are still a little tender!"

After that, the old man's head had two horns, like a sika deer, and his face had changed, his mouth was protruding, his eyes were cracked, his skin turned from yellow to green, extremely rough, and his snow-white beard became wisps and wisps, and finally, nine soft whiskers in the shape of noodles were formed.

Qin Yu suddenly realized and exclaimed, "You, you are the nine-bearded old dragon!"

The old man has become too similar to the dragon king in the TV series "Journey to the West", he is a Chinese, but anyone who has watched Journey to the West can recognize this species!

"Hahaha! It's too late to regret!" The old dragon laughed, inserted the air hole with a crutch, and easily picked up the manhole cover, Qin Yu only felt a fishy smell of the ocean, spewing out of the well, choking his nose and spicy eyes, he couldn't breathe, he couldn't see, and when he eased up a little, he opened his teary eyes, only to see that the old man had completely turned into a dragon body (the dragon's real body came out of the well, and the old man was one), so big, just the height of the head, it was about the same as Soho's height.

"Run!" Qin Yu knew that he had been tricked, and he would definitely not be able to kill this dragon, so he hurried to La Suho.

Soho was so frightened that her legs and feet were weak, she was paralyzed on the ground like mud, looking at the faucet stupidly, Qin Yu pulled Soho and dragged her, so she got up, and helped her to escape in the direction of the subway station, before she could go far, Qin Yu suddenly felt that his ankle seemed to be entangled by something, and when he looked down, it was a slimy thing, like a dead snake that had just fallen into the water and had just been fished out, Qin Yu turned around and found this "dead snake" It was one of the nine whiskers of the old dragon, extending more than ten meters long, while the other dragon whisker was wrapped around Soho's ankle, pulling both of them in.

The old dragon over there, lying on the track, unhurried, unhurried, looking at Qin Yu and Soho with a smile, as if he was deliberately playing with them.

In a hurry, Qin Yu let go of Soho, pulled out a dagger from his boots, bent down and slashed at the dragon whisker, the dragon whisker seems to be soft, but it is very tough, cut with a knife, just like cutting a car tire with a plastic toy knife.

"Roar!" After a dragon groan, the dragon's whiskers contracted, Qin Yu and Soho were both suspended into the air and hoisted back above the wellhead, Suho hung upside down, already frightened and fainted, like a tender suckling pig hanging on the assembly line, let people slaughter, Qin Yu was still resisting, using his abdominal muscles, lifting his upper body, and continuing to cut the dragon's whiskers hard.

It's useless, it's not cutting, it's grinding, because it doesn't move at all!

After grinding a few times, Qin Yu gave up his futile resistance, hung down, looked at the dragon's head, and gasped and said, "Lord Dragon God, I have no intention of offending, please forgive our lives!"

The old dragon sprayed water vapor with the thick nostrils of a mineral water bottle, sprayed Qin Yu's face, and when Qin Yu wiped off the water on his face, he saw that the old dragon opened his bloody mouth and was using the dragon's whiskers to send him and Soho into its mouth!

"Oh, stop! No, shut up! We don't have good food! Also, I, I didn't take a shower last night, hey, it's dirty!"

The old dragon was unmoved, and continued to send the two "human sausages" into his mouth, probably because he hadn't brushed his teeth for hundreds of years, the dragon's mouth was extremely smelly, and the fishy smell of the ocean that Qin Yu smelled just now was the old dragon's bad breath, but now it has become a strengthened version, and the poisonous gas is general, which directly stunned Qin Yu, and just when his consciousness was gradually lost, he only heard a loud shout from behind his ear: "Quickly release people, spare your dog's life!"

Qin Yu listened to the timbre and knew that it was Bai Rou'er who was back, a trace of hope ignited in his heart, the desire to survive exploded again, and the hormone secretion increased rapidly, he opened his eyes suddenly, held his breath, and stabbed the dagger in his hand into the soft flesh of the old dragon's mouth.

Poof! The whole dagger was stabbed in, and the painful old dragon howled, and the dragon whiskers flicked out, throwing Qin Yu and Soho out.

In the air, Qin Yu opened his eyes and was secretly saved, but he didn't expect that after the old dragon threw out the two, the dragon whiskers followed closely behind, and successively wrapped around Qin Yu and Soho's waists, pulling the two back, this time it didn't eat, but directly stuffed them into the lock dragon well, the dragon whiskers were released, Qin Yu lost his center of gravity, his body fell straight down, not how high he fell, the skin strand pier was on the top of the well wall, but he couldn't sit down, the angle of the well wall was too tilted, Qin Yu continued to slide to the bottom of the well like sitting on a slide, and after sliding for about half a minute, Qin Yu's feet finally touched the bottom of the well and stopped。

"Ahh......h
