Super Weapon Swap System

1"System, can you open the front door?" At this moment, Qin Guan was talking to his brain.    1

    

Wasn't this system used to exchange equipment from the cemetery? Right now, he had entered a real graveyard.    

    

Qin Guan really had no interest in playing a secret room escape game and needed to find a secret key or something like that. He didn't think that way. Rather than looking here and there, he might as well directly ask for help.    

    

At this time, Qin Guan could only ask for help from the system. This was his right-hand man. Besides, the system seemed to be very excited?    

    

"No, my functions are limited now. You can only use the Weapon Graveyard system." The system said: "Furthermore, you need to exchange equipment from another time and space Items from the same time and space cannot be exchanged"    

    

The System seemed to have understood what Qin Guan meant. It was very simple. He could exchange the door for a while. He could move the hidden door to the open stairs. Coincidentally, this was the road and the other side was a dead end.    

    

Qin Guan did not feel any pressure blocking the path of the so-called archaeologist. The archaeologist had killed the soldier from Bear Country with a gun. Such an expert must have had a lot of murders.    

    

Therefore, with the professor down there, he felt panicked. It would be best if he was stuck in the back.    

    

However, the system could not change the location of the two doors.    

    

"Then, what can I do to move this door?" Qin Guan continued to ask.    

    

"Sorry. This has exceeded my ability." The System said.    

    

This is too difficult for the System.    

    

After coming out of the system's conversation, Qin Guan pointed to the opposite side of the stairs. "It's here. But I don't know how to open it."    

    

"I think it's here too." Xiang Jing said. She judged based on her experience. She knocked on the stone wall and knew that it was empty at the back.    

    

Now, she knew that the real entrance was here, but there was no way to open it. What should she do?    

    

Xiang Jing gritted her teeth. It seemed that she could only use violence to resolve it.    

    

She took out a few pieces of rubber from her backpack and pasted them on it. Qin Guan was shocked. "We can't do this!"    

    

Of course Qin Guan recognized that it was the most common C4 bomb! It should be fine to use these explosives to open the door, but there was nowhere to hide!    

    

The top of their heads was almost sealed off, and there were only these unfathomable stairs behind them. If they directly used explosives here, the flames produced by the explosives would be enough to overturn the stone slab above their heads. At the same time, many flames would roll on the steps behind them. Because of this, there was no place for them to hide!    

    

Xiang Jing scratched her head. This was indeed a problem.    

    

Thus, she could only put the explosives back into her backpack. She continued to look around, looking for the location of the mechanism.    

    

At the same time, Qin Guan returned to the system. The Exchange Stone Door was indeed not allowed. It had exceeded the scope of the system's functions. However, it could still function within the system's framework.    

    

He only needed to find a weapon made of stone in Weapon Graveyard and exchange it with a small weapon. Wouldn't this matter be solved?    

    

Qin Guan found that his brain was becoming more and more flexible. This was almost the only way he could think of.    

    

But only in the primitive society would there be weapons made of stone, right? It was too difficult for him to find such a weapon.    

    

Qin Guan kept entering the menu and flipping through them one by one. He hoped to gain something.    

    

However, in the Weapon Graveyard of his future life, it was very difficult to find a stone weapon!    

    

He searched the entire Asia, but found nothing. He searched the entire Europe, but still found nothing.    

    

In human history, the earliest weapons should be made of stone. After all, humans started from the Stone Age. But none of the Weapon Graveyard had these weapons.    

    

The Weapon Graveyard might not be the final destination of these weapons. If a large-scale war broke out, these weapons might be put back into use. Even the most outdated weapons in the Han Country did not return to the furnace to be reforged. It was to deal with such a terrifying large-scale war.    

    

However, no one would use the weapons from the Stone Age as backup weapons.    

    

Then, where could he find the weapons made of stone?    

    

Fortunately, when he entered the weapon system, time did not flow. Even so, after Qin Guan flipped through it for half a day, he was still very impatient.    

    

He did not gain anything in New Continent State.    

    

Then he would go to Southern Continent and take a look!    

    

Finally, Qin Guan found something in an unknown and completely abandoned Weapon Graveyard.    

    

In the worn-out T-54 tank provided by Bear Country, Qin Guan found a stone knife.    

    

It was a black and short stone knife, and it was only 30 centimeters long. Its entire body was emitting a black light, and it looked quite sharp.    

    

There was a leather cover on the outside of the knife. This stone blade was not a weapon, but Tankers's spoils of war. It was even used as an ornament to wear. In the end, it was left here.    

    

Qin Guan looked at the black blade and his heart felt heavy.    

    

In the 16th century, when the people of C Country broke into the New Continent Continent, they discovered that the people of this country used stone weapons as weapons. And the residents of this country were the Aztec people.    

    

The Aztec people bravely resisted the invasion of the C Country, and when they used the guns and cannons of the C Country, the weapons they used were weapons made of obsidian.    

    

Unfortunately, it was destined to be useless.    

    

It was only 400 years ago, and this stone knife was still intact. It only needed 10 Spirit Focus to be exchanged. After all, its value was too low.    

    

"Exchange immediately. Let it exchange with the fixed point of the stone door." Qin Guan began the exchange of weapons.    

    

Based on the principle of equal exchange, the entire stone door would definitely not be able to be exchanged for such a stone knife, but it could be opened! This was the experience gained from the exchange of Sheridan.    

    

The exchange began!    

    

There was almost no fluctuation in the space. There was only that stone saber on Qin Guan's waist. When Qin Guan returned to reality, Xiang Jing was still thinking hard about where the mechanism was.    

    

Later, he would show her something powerful.    

    

Qin Guan smiled and said to Xiang Jing, "Now, look at my special ability. I only need to push hard to open this stone door."    

    

He originally wanted to say it in an exaggerated manner, but he thought about it and decided not to boast.    

    

Qin Guan had already planned how he would proudly open the door.    

    

However, Xiang Jing did not give him a chance. When Xiang Jing heard Qin Guan say this, she had already taken a step forward and used the side of her body to push the theoretical stone door.
