its 334: 500 years ago

There are five large bookcases in the lobby. There are hundreds of books of different thickness in each bookcase, and there are almost two or three thousand books in total. Cheng Xingxing carefully took out a few books from each bookcase and found that the five large bookcases were arranged in order from left to right, and the more precious the books were, the higher they were.

In the first bookcase on the left, there are basic readings of forging and armor, and the second bookcase is also this kind of book, but it is no longer about basic things, but comprehensive cultivation. In the third bookcase is the secret book of forging, and the fourth bookcase is the secret book of forging armor. These secret books are written by masters of various schools and seem to be very valuable.

The fifth bookcase has the fewest books, but the star feels the heaviest, because what is written on these secrets is not a door or a secret book or a secret book, but someone's note. Together, there are only more than 30 books, and the remaining more than a dozen are one person's notes.

It says "Unparalleled Notes".

"Unparalleled notes?" Cheng Xingxing couldn't help laughing, because he remembered Zhu Wushuang in My Own Swordsman. But he knows that what is recorded in these notes is definitely not the four-character philosophy of life, but should be the owner of this study, the lifelong experience of cultivation.

He didn't dare to move these notes anymore. He just gently put them away and slowly retreated.

There is a pile of gravel in the middle of the lobby, and there is a big hole in the corresponding ceiling. Cheng Xing raised his torch and looked up, knowing that it must be the roof dug by the local beasts. At this time, the roof was blocked by some big stones, which looked quite strong, but Cheng Xingxing couldn't help worrying for fear that these stones would fall down and destroy this place.

We need to carry out the rescue operation as soon as possible! Cheng Xingxing thought in his heart and quickly ran out of the lobby.

It's not good to get in and out of the hole of the beast alone. Cheng Xingxing knew that there must be an entrance and exit in the underground palace, so he looked for it carefully.

In addition to this large study and that bedroom, the underground palace also has several houses piled with earth and stone, wood, gravel and metal, as well as several forging rooms of different sizes and smelting rooms. In addition to these places, there is also a square hall composed of several small doors and walls. Cheng Xingyi tried to open a small door, but it turned out to be a big disaster.

With the opening of the small door, some squeaks also sounded. Cheng Xing didn't pay much attention to it. He held the torch and walked in. As a result, as soon as he took a few steps, he was dumbfounded, because the firelight lit up the place, reflecting the shadow of a humanoid with four arms.

I went there, and it was a warehouse where this murder weapon was stored for a long time!

As soon as Cheng Xingxing had time to exclaim, more than a dozen four-armed armored men moved their rusty joints and moved slowly. Not waiting for Cheng Xingxing to turn around and out of the house, these armored men had already waved their weapons and rushed up.

Cheng Xingcheng sighed and had to hold a torch in one hand, pull out a long knife in the other, and fight with these armored men. With his strength, as long as he has weapons in his hand, it is not difficult to deal with these iron guys, but the problem is that the room is not big. His knife is too long to be used. After fighting for a long time, he made himself dangerous, but only destroyed two armored men.

This won't work! Cheng Xingxing frowned and suddenly slammed the long knife forward, piercing an armored man's chest. However, this kind of damage does not need to be taken seriously for the Iron Armored Man. The Iron Armored Man just fell back, and a fish jumped up again and still rushed to become a star.

Without a long knife, Cheng Xingxing will carry the dragon's old dragon claws, grab it left and right, break the arms and legs of the iron armored people, and then bombard them with the blue dragon ball. As a result, the battle lasted for more than ten minutes before all the armored people were put out.

Cheng Xingxing sat on the ground and gasped for half of the weather. Thinking about those small doors, he decisively gave up the idea of opening them one by one. He stood up and started looking again. Finally, after bypassing the two corridors, he found a place like an exit. There is a huge stone door with complex patterns. Cheng star thinks that it may be a "array" that can realize various functions.

He tried for a long time, but he couldn't move the huge stone door at all. In desperation, he had no choice but to return to the hole in the bedroom and climb out along here with the beasts.

"Little brothers, you go by yourself. I have to go back and report it quickly!" After getting out of the hole, Cheng Xingxing didn't care whether the other party could understand or not. He rushed to the beasts and turned around and ran away. Not long after, he jumped off the wall and returned to the door. This time and again, he tossed the dark whistle of the wonderful door in the wild. Fortunately, there was always a torch in his hand. After the dark whistles were shocked, they found that it was their own door owner, so they were not surprised. But the problem is whether you are shocked or not is one thing. If you find that the door owner is running in the wild, you have to immediately send a report to the door according to the rules. It's really a tiring thing at night.

Everyone had gathered in the door owner's house. As soon as they saw the star come back, others didn't say let it go. Mulan rushed over first and grabbed his ear: "Is there anyone like you? Huh? Is there such a thing? In the middle of the night, a gatekeeper said he would run away. Do you know how worried everyone is?

"Saved?" Lin Jiang asked anxiously.

"It's all saved." Cheng Xingxing patted his chest and looked proud: "If the master of this door comes out in person, can there be any difference? You tell Mr. Tong that they will come back in a while.

"Great, I'm going now!" Lin Jiang cheered first, and Sa Yazi ran away first. It's not that he is in a hurry to report to Tong Meng, but that Shu Xiaoya looks at him with a bad look and pretends not to see him.

"Master, I think you have done something very improper this time." Shu Xiaoya also had a gloomy face and said angrily, "You are not a ranger. You are the master. There are hundreds of people behind you. You can't do whatever you want so irresponsibly. Forget about things like Ling Xianhui before. This time, in order to save a few foreign beasts, you ran away without saying a word. What do you think everyone is?

"I was wrong." Cheng Xingxing's face was sweaty. He hurriedly arched his hand and bowed: "I shouldn't have run away without telling everyone. It's my fault, but this time I made a big discovery!"

With that, he took Mulan's hand and startled the girl: "What are you doing?"

"Good thing!" Cheng Mingxing said, "You know what I found when I ran to save those beasts? The underground palace, a underground palace where a peerless master lived 500 years ago! Guess what kind of peerless master is that?

After saying that, he turned his eyes to Kaobu City.

Everyone was attracted by his words and forgot to blame him for a moment. They just listened curiously. Seeing him watching Kaobu City, everyone also looked over together, which made the little boy a little at a loss: "What are you doing?"

"Little city, this time you and Xiaolan are completely developed!" Cheng Xingxing smiled and said, "Do you know what I met in the underground palace?"

"What?" Almost everyone asked together.

"Monster." Cheng Xingxing said excitedly, "A humanoid monster with four arms! Do you know what kind of monster it is? That's a man made of steel!"

"Robot?" Shu Xiaoya was stunned, "It's impossible. Yunsu World is a... Anyway, there can't be such a developed technology in Yunsu mainland!"

"This involves another thing I found." Cheng Mingxing looked at Mulan and Kao Bucheng and said excitedly, "It's a library with five large bookcases and a collection of thousands of books!" Do you know what books are in it? Think about it, think about it!"

Kaobucheng looked at him with a certificate, and after a long time, he muttered, "Is it... Is it a book of forging and armor?"

"It's all ancient books!" Cheng Mingxing nodded and shouted, "From the most basic books, to the notes of dozens of top masters, and more than a dozen things called 'Wushuang Notes', I estimate that the Wushuang Notes are the one who plundered the secrets of the major factions five hundred years ago, thus completely weakening the forging and armor skills that flourished in the mainland of Yunsu. Master's notes!"

"Oh, my God!" Kaobu City and Mulan were all stunned. Half a day later, Kaobu City shouted excitedly: "Where is it? Where is that place?"

"Find someone, bring a torch, let's go now!" Cheng Xingxing said to Shu Xiaoya that Shu Xiaoya didn't say a word, turned around and rushed out, and organized a team in a moment.

Under the leadership of Cheng Xingxing, the team set off quickly with a torch and came to the small valley. In front of the giant rock, Cheng Xingxing pulled Kaobu City and Mulan to get in first. After arriving at the underground palace, he didn't care whether others could get in or not, and first came to the gate full of pictures.

"Where's the library?" Kaobu City and Mulan asked him anxiously almost together.

"The top priority is to open this door first." Cheng Xingxing pointed to the door and said, "Open the door, and our team can come in quickly. Otherwise, with a few people, when can we save those ancient books?"

"I see." Without saying a word, Kaobu City stared at the door and looked at it, and Mulan also looked at it with concentration.

"What a complicated array!" Mulan only looked at it for a while and exclaimed, while Kaobucheng had been frowning, as if a high school examinee was facing the high school examination paper that determined the direction of his life.

"I roughly understand!" After a long time, Kaobucheng turned around and said to Cheng Mingxing, "Let's go to the library first. This door can be opened, but I need to make some tools to open the door first.

"As long as you can open it." Cheng Xingxing nodded with relief.

At this time, Xun Xianxue, You Liang, Shan Shusheng and others had climbed down the hole, and Cheng Xingxing took this group of people to the library. At the door of the library, everyone was surprised to see the wreckage of the two armored men killed by stars. They couldn't believe that these steels could still be active to attack others not long ago.

Entering the library, under the advice of Cheng Xingxing, Kaobu City carefully pulled out an ancient book and read it greedily.

"That's right, this is definitely the painstaking work of the masters at the peak of forging and armor forging 500 years ago! Brother Xiaoxing, we have developed this time!"
