Although the second floor is already crumbling, the special structure of the museum can still make the main building stable for a while longer. Jiayu and Professor An were able to find the Precious Collection Vault without any problems.

A huge cement stone smashed a large crack in the sturdy safe door, and the two of them forcefully pulled the door open, revealing countless large and small wooden boxes in front of them.

Jiayu and Professor An rummaged through a pile of treasures, and finally pulled out a worn-out cardboard box 1 meter long and 30 centimeters wide from a corner.

Opening the box, a large, unspeakable sword reveals itself in a pile of scrap newspapers. This sword, including the sword body with the hilt, is close to 1 meter, and the cardboard box has a small hole poked out.

In terms of form, it does not look like a Bronze Age work. Because the bronze sword is generally more than 50 centimeters in length because of the material, the most classic Yue Wang Goujian's own sword is only 55 centimeters long, and it is now the length of the mountain knife, which is not a little worse than the sword style described in Xianxia as "a sword cold light fifty states".

Professor An rummaged through the glove box next to him for a long time, found two plastic gloves, and motioned for Jiayu to bring them.

After all the preparations were made, Professor An gently picked up the simple shape of the sword from the tip of the sword, Jiayu held his breath, gently grasped the hilt part, took the sword out of the box, and the two tiptoed to the middle of the second floor, where a large opening opened in the ceiling and the light was brighter.

This sword is a one-piece weapon, that is, the body and hilt are forged from a single piece of metal. The sword body is straight, the main body of the hilt, that is, the grip part, is called the sword stem, which is a standard cylindrical shape, and the sword head, that is, the tail of the hilt, is a round ball.

Jiayu was a little disappointed, thinking to himself, "An iron pipe, there is no undulating carved line, this is not very easy to hold, you can't hold it hard, it is easy to slip, it seems that if you want to use it in the future, you have to wrap a circle of cloth densely, it is barely suitable." ”

The sword grid, that is, the handguard of the sword, is a square hexagonal thin piece of iron, without the patterns commonly used in bronze swords such as Pixiu and gluttony, it is a piece of iron.

Jiayu frowned, "It's not tall at all!" ”

There are no inscriptions on the sword, nor do they have the patterns common to bronze weapons like lattice. There are still some rust on the hilt and body of the sword, like the pulp of ancient bronzes, but the sword body is not wide, which is comparable to the eight-sided Han sword often sold in tourist souvenir shops, but it is slightly narrower.

The overall lines of this sword are smooth, not like an ancient work, but like a saber made by some modern swordsmith.

Professor An said that he secretly took it out and dated it with carbon-14, and the final conclusion should be about 100 million years ago, 100 million years, not to mention bronze, even stone swords have not yet appeared.

Professor An told Jiayu that he had told the person in charge of the research group about 800 trips, and that this weapon was not made of bronze, although it was a little greener, and although it still had a little bronze pulp, it was not bronze, and it was not an egg......

Professor An, who put forward the theory of prehistoric civilization, was ridiculed and isolated by the museum because he touched on the taboo of archaeological work - the theory of prehistoric civilization, and finally had to be transferred to the university to teach children how to raise sheep and pigs and distinguish trilobites......

Speaking of this, Professor An gritted his teeth and kicked his chest, in pain.

……

……

Jiayu and Professor An are secretly appreciating magical weapons, and Jiayu habitually doesn't believe in Professor An's words, after all, whether it is now or in the past life, Professor An is too good at bragging, and he doesn't know which sentence is true...... But after looking at it for a while, they made a new discovery.

The body of the sword was exposed to the air, and in the sunlight the sword seemed to come alive and breathe.

The blade began to glow, and the patina was melting.

Jiayu glanced at Professor An and asked, "Were you blind at that time?" Can't see such a bright light? ”

Professor An's eyes were straight, "It's impossible, there was no such light when a light bulb of several hundred watts shone at that time...... How so? ”

Jiayu held the hilt of the sword, and could feel that the hilt was slowly deforming, gradually conforming to the shape of his palm, and was so frightened that he almost threw away the ancient relics.

The rust on the sword body was slowly dissolving, covering the sword body like flowing water, and the glow that erupted on the sword body was gradually wrapped in this layer of substance, like a divine sword in its sheath, and the blade was gradually restrained.

The weapon quickly relegated to normalcy, no longer glowing outwards like a glow stick.

Jiayu hurriedly asked Professor An: "At that time, you didn't have this function?" ”

Professor An shook his head, "At that time, the gray fluttering was just this shape, it was a bronze sword, and it was like a semi-finished product that had not been processed, so the expert group felt that the research value was not great, and it seemed that it was blind."

"It's just right, as a self-defense device, my dinner knife cut more than 800 insects, and the blade is gone" Jiayu wanted to use it for two days first, and then turn it in when the situation stabilized.

Professor An glanced at Jiayu sideways, "Blow, blow hard, and there are eight hundred insects, eight can exhaust you to death" Holding the sword, he looked at the new shape of the treasure of the town hall in a daze, as if he had lost his soul. After watching it for a long time, he gritted his teeth and handed it to Jiayu.

……

In his previous life, Jiayu actually had very little time to practice swords. Because the popular attack weapons of the Evolver are mainly all kinds of knives! The battle of the large army, the assault of the small detachment, it is relatively easy to exert force with the knife, and the only few sword exercises are all second-class goods, and the level is not, and the patronage is handsome, and as soon as the fight starts, it is swallow......ed by the monster in one bite.

Jiayu held the sword with one hand, the tip of the sword stretched down obliquely, his eyes condensed, then he closed his arm, raised his wrist, and compressed his arm like a big bow, compressed, compressed to the extreme, and then collapsed straight forward like a photoelectric flash, and the power rose from his waist, transmitted to the upper arm, and then transmitted to the elbow, wrist, and fingers...... A little cold star on the tip of the sword stabbed straight forward, exhausted, but the momentum was inexhaustible, and the tip of the sword burst out with three cold stars, circling and circling, and then retracted the sword and slashed down......

In the ruins of the empty museum, an ordinary human is practicing an ancient swordsmanship on the earth - "Dharma Sword", although the dance component is a little more, but it can also play a certain role in actual combat.

Professor An was stunned by the side, and it took him a long time to react, and shouted at Jiayu, "Stop, stop quickly, this is a cultural relic, a cultural relic from 100 million years ago, why don't you stop it quickly......"

————————————————————

Back in the hall, Jiayu showed Chen Qin his newly acquired treasure of the town hall.

Chen Qin never knew that Jiayu could dance swords, after all, swords were ritual weapons in ancient China, and they had long been abandoned in actual combat, and the army mainly relied on knives to kill enemies, and the role of swordsmanship was gradually decreasing.

Jiayu was infected with Professor An's problem, and casually bragged that he had a relative who was a hidden descendant of Taijiquan, and he practiced murderous swordsmanship, not exposed in front of ordinary people, and the swordsmanship practice was fast, accurate and ruthless, and learning swordsmanship routines was also to make his sword pierce on time, and the speed was faster, especially in terms of exercising, the effect was still good.

After that, Jiayu rummaged through the ruins and found the scabbard of a handicraft sword, put it into the sheath, and looked like a fake found in a tourist goods store.

I found the nylon strap in the miscellaneous items again, put the sword behind my back, jumped a few times, moved my body, and felt that it was okay, and there was no obstacle to my body movements.

……

"I feel like the earthquake during the day today, it's not an earthquake", while sheltering from the rain, Professor An began to analyze the changes in the earth, and Jiayu nodded.

The bonfire in the museum hall outlines the side of Professor An's obscene face, but it makes people feel sacred and solemn: "An earthquake is the release of energy between the plates of the earth, and since it is an energy release, it must cause a huge sense of shaking and a lot of noise, while yesterday's earthquake is more like the reshaping of the earth's crust from the microscopic level, the mountains become plains, and the plains sink into basins...... It may be that the matter in the original mountain has changed, and it is the same as the plain becoming a mountain range. ”

Jiayu looked at Professor An and said in his heart, "Yes, under the premise of not having any observation equipment, there is an inference, and it is basically the same as ten, and the basic skills of scientists are still very strong." ”

……

"In the evolution of organisms, such as the theory of evolution in Darwin's theory, it should be said that it has always existed, but there have been qualitative changes, do you know that there is an unsolved mystery in the history of the evolution of the earth, called the 'Great Oxidation Event'?" Professor An entered the teaching mode.

Professor An went on to explain: "The 'Great Oxidation Event' occurred about 2.6 billion years ago, when there were only microorganisms, no animals, and no plants on the earth, and all living things on the earth did not need oxygen at that time, and oxygen was a highly toxic gas for these microorganisms, but instead, The 'Great Oxidation Event' happened, and the blue-green algae began to produce a large amount of free oxygen in order for us aerobic organisms to survive and evolve, just like the poison produced in your home, you still produce every day, without stopping at all, just to prepare for the offspring. ”

Professor An later said, "There are five mass extinctions on the earth, one is called the Permian era, and our current view is that there was a volcanic eruption in Siberia in Russia, and the magma erupted for hundreds of thousands of years, so that 95% of the species on the earth were extinct. My theory is that every mass extinction on Earth has a purpose, which is to give mammals like us a chance to evolve."

Jiayu understood: "You mean that now is an era of mass extinction?" And only our surviving humans have a chance to evolve? ”

Professor An nodded and said, "I hope it still won't, such a leap evolution may mean the end of human beings, no matter how you jump, you have to make way for the creatures that evolve later, the end of an era." ”

All three fell silent, all sensing that the future was dark.

……

When the rain stopped, they were about to go out to see the sky, when the earth dog heard the sound of an airplane in the sky.

Jiayu jumped up, ran out, and saw several military helicopters hovering in the sky in the distance, and a loudspeaker came from afar: "Please meet the citizens of Qingcheng who can act on their own to gather at the government building and receive help!" Citizens of Qingcheng who are able to act on their own are invited to gather at the government building and receive help! Citizens of Qingcheng who are able to act on their own are invited to gather at the government building and receive help! ……”

In the distance, helicopters can be seen descending, rescuing people from the edge of cliffs, on top of buildings, and in the open space of the square.

"Looks like there's hope, let's go."

The treasure of the town hall on Jiayu's back led a few people and began to walk over the mountains and mountains towards the assembly place, and the distance was not far away.

……

The catastrophe of heaven and earth in one day and one night has hit the human race, which claims to be the "spirit of all things", and in the short interlude after the evolution drama has just kicked off and the insects have been wiped out, China, North America, Europe, Africa, ...... Those who survived leaned out from under the rubble, in the grass, and in the trucks, looking at the land that had become unrecognizable at the dawn of the new century, and took the first steps in the struggle to survive.

Humanity began to assemble. In the mountains, grasslands, caves, and shadows, animals and plants have finally joined the evolutionary army, new life forms are being born, and ancient monsters are returning.
