It's not that they haven't tried to knock on the courtyard walls in other locations, but the hardness of the courtyard walls in other locations is much higher, and they can't smash the slightest crack after smashing them round. They somewhat believed in Zhu Beichen's intuition, the wall that Zhu Beichen found was the most vulnerable part of the entire courtyard wall, although they didn't know the inside story, based on the idea of survival. The ground was littered with layers of debris, and the crystal debris looked more like jade chips, but the hardness was higher than that of jade.

Zhu Beichen nodded, looked at the sweaty two with confused eyes and asked, "How is it, is there something?" ”

The fat man threw the jade hammer aside, rolled his eyes and said, "I almost burped, I was tired to death." I don't know if there's something or not, at least the walls here are different from other places, and it's hard to achieve this effect, and if we continue to smash it, we might go out. Master Zhu, are you sleeping peacefully? ”

Another hammer slammed down, and Seven swept the debris from the ground, an object that reflected the light caught his attention. A strangely shaped sharp object was picked up by him from the jade shavings, the new surface was shining with a metallic luster, and the triangular sharp knife head was slender in the middle and a handle at the end. Obviously, this is a weapon, about twenty centimeters long, and at best it is a dagger that can be judged to be a good hand. Cutting through the triangular blade head, the skin of Shichima's hand was torn open with just a slight touch, and the blood slowly seeped out.

"Silk!" The three of them couldn't help but take a breath, at first they really underestimated this weapon, the sharpness had reached such a level.

"A conical sword?" Shichima muttered to himself in a low voice, repeatedly comparing the shape of the weapon in his memory, and then referring to the ice blade in his hand, which he called the 'conical sword'.

"That's what you said a few hours ago about hearing metal hitting the wall?" Doubts, speculations, complicated eyes looked at Zhu Beichen, what a terrifying thing that a dead object could hit the wall at a fixed frequency.

It is rumored that this weapon is not used for battlefield fighting, but is buried in the foundation during the construction process as a tool to ward off evil spirits, and the complete tapered sword atlas was found in a tomb of the Ming Dynasty in Shaanxi. Some scholars have speculated that the year of this tomb is the end of summer, but only the map of the conical sword weapon is preserved in the tomb, and no physical excavation has been made. Therefore, the excavation speculation of this atlas has caused a lot of discussion, the argument is why the tomb was buried with a atlas instead of using real tools, and then the purpose of this conical sword weapon, whether it was a weapon or had some other purpose?

"I remember that in the 70s, there were news reports about this tomb and the unearthed conical sword weapon, and the tombs of the Xia and Shang periods did not retain a complete conical sword weapon, but a map was preserved, and even the casting process and composition ratio were not explained, obviously this town house tool has been lost during that period." Shichima said softly, carefully avoiding damage to the blade with one hand.

The knowledge of the seven rooms really opened their eyes, and the fat man's eyes seemed to remember something, and he said in surprise: "I remember, I also read this report, but I didn't pay much attention to it." "Since even archaeologists can't study the purpose of the conical sword weapon, how can Qijian conclude that this is a tool for building the foundation of a town house?

Zhu Beichen couldn't bear it anymore, and became more and more curious about this weapon, and hurriedly asked, "Then how did you determine its use?" ”

Shichima smiled slightly, straightened his scattered hairstyle, and for the first time played a cool pose and half-squatted, holding a conical sword in one hand, his eyes glanced at the pattern on the cone-shaped face and explained to the two: "Have you ever seen this pattern?" In the ancient Jiuli clan, it is a commonly used town house animal pattern, and there are very few people who know this beast pattern due to the age. But any instrument with this kind of animal pattern is a town house utensil. Take a closer look, in fact, this is a Pixiu shape that belongs to the characteristics of that era, depicting the legendary Pixiu with lines, and then elongating it through artistic processing, forming a kind of animal pattern. ”

His judgment is completely grounded, one point is the Pixiu beast pattern, in the ancient Jiuli culture, Pixiu is the town house beast. I saw that he turned over the other side of the conical sword weapon again, and compared to the back of the Pixiu beast pattern, it was densely packed with all the incantations, carved with a bright blood-like paint, which made people a little dizzy from a distance.

The only arm of the seven rooms trembled a little, and said: "These runes are orthodox Wu clan charms, in fact, it is said that the Dao methods in the world have the same end, and many of the Dao Sect's runes and seals are derived from the ancient Wu clan, that is, the Jiuli clan. This is the image of their most primitive period, and it is also the most complete period. In the process of inheritance, the shape and writing style of the talisman seal have changed, the original elongated lines have been further simplified and shortened, and the raw materials used for writing have also changed. Most of the people we use now are cinnabar, and the ancestors at that time used human blood, which was not mixed with water at all. ”

Hesitating, Zhu Beichen, who originally planned to borrow it from Qijian to play with, also hesitated, this kind of thing is too evil, and he faintly feels that the antiquities of thousands of years ago always have such an evil nature, which makes people fearful.

"Okay, I'll put this thing away first. It's pretty sharp, much more powerful than our daggers, and will be useful in the future. Shichima carefully found a piece of cloth to wrap the blade around the sword to avoid cutting himself, and placed it in his backpack.

"Can you please not take this thing with you, it's quite infiltrating." When Zhu Beichen remembered that the talisman on the back of the conical sword weapon was written in blood, he couldn't help but feel a chill in his heart.

Seven was noncommittal, and responded with a smile, beckoning the fat man to continue selling coolies, seeing that the hole in the wall was getting bigger and bigger, and almost the next moment the dawn of the outside world could penetrate into this courtyard.

A heartfelt thought echoed, summing up the strange sounds they had heard a few hours earlier, and the seven had indeed found something within the wall, which, according to him, had been buried in the wall when the house was built. But Zhu Beichen always felt that the voice in the dark was actually leading him to find the weakest breakthrough, someone was manipulating everything here, a pair of eyes were watching this courtyard, and he was reminded step by step how to go, how to get out of this courtyard to the streets of the ancient city.

Thundered~

The loud noise broke Zhu Beichen's thoughts, and at first glance, the hole in the wall had formed a hole for people to enter and exit, and the outline of the street could be faintly seen outside the hole.

"Got through." The fat man excitedly drilled his head and looked at the outside worldview, shouting excitedly, and getting carried away.
