At the top of the list are biological and chemical weapons, and behind are nuclear weapons.

Meng Qi knows that in war, the most despised weapon is biological and chemical weapons, this kind of weapon uses bacteria and viruses as minions to invade the enemy's body and make the enemy die in pain, war itself is cruel, but if soldiers are allowed to die in this way, it adds to the horror and anti-humanity of war.

On the earth back then, sometimes we would see reports about the discovery of biological and chemical weapons discarded before the war in such and such a place, which often caused fear and panic in an entire region, and under the level of modern technology and medical treatment, biological and chemical weapons would cause great harm, not to mention the backward society in which Meng Qi is now living.

Meng Qi had no doubt that if he released a plague bomb, he could directly destroy a Quyu country.

He didn't even think about it, he ignored this weapon.

Behind them are the most powerful nuclear weapons, including hydrogen bombs, atomic bombs, neutron bombs, three-phase bombs, antimatter bombs, etc.

When Meng Qi used the Colt M2000, he knew that all the strategy weapons used in this world were normal attribute power, not the power in the game or the power seen on TV.

For example, the standard hydrogen bomb, Meng Qi has seen the report of the test hydrogen bomb called 'Big Ivan' detonated by the former Soviet Union, this hydrogen bomb directly destroyed an area of 80,000 kilometers, which is equivalent to the power of 50 million tons of TNT bombs, and the explosion power is almost equivalent to the area from Shanghai to Zhenjiang to be razed to the ground, and no grass is born.

If Meng Qi exchanged for a hydrogen bomb and detonated it, the hydrogen bomb would be powerful enough to destroy more than a dozen contiguous countries.

Meng Qi shook his head, like biological and chemical weapons, Meng Qi is also not ready to use nuclear weapons, what he wants to do is to conquer the world, not destroy the world, he wants thousands of miles of fertile land, great rivers and mountains, not ruins and ruins.

Out of curiosity, Meng Qi looked at the satiety required to exchange these nuclear weapons, but to his surprise, the exchange prices behind these nuclear weapons were all three question marks.

'What's going on?' Not allowed to redeem? Still not eligible for redemption? Meng Qi was a little strange, if it was not allowed to be exchanged, why did it still appear in the system mall?

No one answered Meng Qi's question, since Meng Qi refused the system's plot mission last time, this system has never spoken, as if it abandoned Meng Qi.

'Forget it, take it one step at a time, I don't plan to use these terrible weapons anyway. Meng Qi shook his head and put the matter behind him.

He called for water to wash his face and feet, washed and went to sleep, but he didn't know that at this time, in the Criminal Department, a night walker was quietly approaching the prison of the Criminal Department.

This man is athletic, very good at light skills, and walks like a wind, extremely fast and without a sound.

At this time, there were four guards standing guard in front of the main door of the Criminal Department, in addition, every ten minutes, there was a patrol of ten people passing here, all of them wearing armor, equipped with long swords, fully armed, and strictly guarding the prison of the Criminal Department, because there was an order from above that there was a very important prisoner in the prison who needed to be strictly guarded.

After sneaking closer, the man in black hides behind a wall, as if waiting for something.

After a while, there was a sudden sound of fighting in the distance, and the patrol team immediately rushed over, and the man in black took this opportunity to suddenly appear, under the cover of the night, his body was like a ghost, and he deceived himself in front of the guard in the blink of an eye, and then the long sword on the waist of the man in black was unsheathed, and the lives of the two guards were harvested in an instant.

The remaining two guards were shocked, and were about to shout, but they were not as fast as the sword of the man in black, and the guards subconsciously raised their swords to block, which was able to block the attack of the opponent's long sword, but before they could breathe a sigh of relief, the opponent's long sword turned over, like a silver snake, directly slashing through the guard's neck.

The guards didn't expect that the other party was using a soft sword.

After eliminating the four guards, the man in black was not at ease, and made up a few more swords on the corpses of several people before running into the prison of the Criminal Department.

The man in black ran all the way, seemingly knowing where the target was being held, and reached the bottom of the prison of the Criminal Department.

The man in black stopped in the last cell, and he looked through the crack in the bar.

A middle-aged man was sitting cross-legged on the edge of the bed, as if resting with his eyes closed, and there were two other prisoners in the cell, both sleeping crookedly, one of them snoring like thunder.

The man in black just glanced at it, and then locked his eyes on the middle-aged man beside the bed, and he confirmed that this person was the target he was looking for, Lord Zhao Qian Zhao, the head of the household department.

He walked to the cell door, picked up his long serpentine sword, and slashed at the fist-sized lock.

With a bang, sparks appeared, but the iron lock was unscathed, leaving only a faint white scratch on the black surface.

'Huh? The man in black was amazed that the iron lock was so strong.

The sound of metal crashing woke up several people sleeping in the cell.

Lord Zhao Qian Zhao opened his eyes and saw the man in black in front of the door, he was stunned at first, and then frowned and said, "Did Lao Zheng send you here?" Go back and tell him that I won't go out until the matter is clear. ”

The man in black glanced up at Zhao Qian, then lowered his head again, fiddled with the iron lock in his hand, and did not answer.

He thought that since he could not break the iron lock, he would use his skill to open it, although it would take more time.

Zhao Qian said with a hint of anger in his voice: "Didn't you hear me talking to you?" Even if you open the lock, I won't go with you. ”

A lean man next to him also woke up at this time, he put his hand into the crotch of his pants and scratched it for a while, then looked outside and said, "Is this brother Tai here to rob the prison?" Haha, Lao Tzu has come out, this unlucky place really can't stay. ”

The man in black outside opened the lock and looked at the man and said, "Are you a big thief Qi Xingxing?" The man in black had a shrill voice, and when he heard it, he used internal force to squeeze his vocal cords and change his voice in disguise.

"Yo? Do you know me? Qi picked up the stars and raised his eyebrows.

"I don't know who picks up the stars, but I'm curious about how you guys ended up in this place." The man in black said, finally opening the lock, and he pushed open the cell door and walked in.

Qi Jiexing stood up, greeted him, and said with a strange face: "It's not to wait for you, it's really embarrassing to be temporarily placed in this cell." ”

Hearing this, the man in black was stunned, and a bad premonition rose in his heart.

Zhao Qian would understand, and he smiled bitterly: "Your Majesty has already guessed that my Zhao family will send someone to rob me and rescue me?" ”

Qi Jiexing scratched his head and said, "Lord Xing doesn't seem to say that. ”

"How?" Zhao Qian was a little strange, he stood up and walked over.

Seeing that the timing was just right, the man in black suddenly became difficult, and the long sword in his hand was like a long snake, swallowing the letter and attacking Lord Zhao.

Zhao Qian was so frightened that he sat directly on the ground, he didn't expect that he thought he was the one who saved him out, and he would kill himself.
