At midnight that night, Duan Shaojun led a group of Dingshan elites and finally returned to Dingshan smoothly.

After returning to Dingshan, Duan Shaojun strictly ordered everyone that tonight's affairs must be kept secret and must not be leaked out, otherwise, they will be severely punished according to the door rules.

After hearing this, everyone nodded their heads in agreement.

Duan Shaojun was very satisfied with everyone's sincere fear, so he ordered everyone to change out of their night clothes and quietly return to their respective residences.

When Duan Shaojun returned to Fuyun Zhai, it was already early in the morning.

When you enter your bedroom, you close all the doors and windows.

After taking all the confidentiality measures, Duan Shaojun excitedly put the package full of rare treasures on the table, and after opening the package, he didn't bother to pay attention to the other gold and silver jewelry, and directly picked up the luxurious and exquisite golden wooden box, ready to see what treasures were inside.

After opening the golden wooden box, he was stunned by the scene in front of him!

The moment the wooden box was opened, the dazzling light shone brightly, illuminating the whole room faintly, Duan Shaojun rubbed his eyes, and after adapting to the dazzling light, he took a closer look and found that inside the wooden box, there were two round and transparent beads.

The beads are about the size of an egg, crystal clear, and the whole body exudes bursts of silver-white dazzling halos, which are extremely brilliant and dazzling.

Seeing such a rare treasure, Duan Shaojun's eyes lit up, and he was almost suffocated with excitement.

He held the two egg-sized orbs with trembling hands, and couldn't help but exclaim, "This ...... Wouldn't this be the legendary pearl of the night? It turns out that there are such strange things in the world!"

These two "Night Pearls" were held in his hands, and there was a faint trace of refreshing coldness, which made Duan Shaojun surprised, when did the Night Pearl of the Heart Dao still have this kind of refrigeration effect?

Holding the two "Night Pearls" and watching them for a long time, Duan Shaojun reluctantly put them back into the wooden box.

Duan Shaojun dragged his chin and sat next to the table, staring at the "Night Pearl" inside the wooden box without blinking, as if he wanted to study it thoroughly, wanting to see how these two things similar to glass balls could emit such brilliant brilliance for no reason.

To be honest, when Duan Shaojun was on the earth in his previous life, he watched many costume movies and television, and the Night Pearl was also mentioned above, and in addition, he also saw the Night Pearl mentioned above in many historical novels and online fantasy novels.

There is no doubt that these materials clearly mention that the Night Pearl is a rare treasure and is invaluable.

Of course, Duan Shaojun didn't know how to judge the concept of pricelessness, as for this pair of night pearls that could exude cold air, Duan Shaojun could be sure that they were very valuable, but how valuable they were, he didn't know much about this.

Anyway, this pair of "Night Pearls" and the rare treasures in the package, as soon as Duan Shaojun obtained them, the task conditions worth one million taels of silver distributed by the system were automatically completed.

From this point of view, the package that Liang Jingzhi carried with him really hid a lot of valuable things.

Other pearl agate, jade and jade, although they are also very valuable, but compared with the pair of night pearls in front of them, it is estimated that they are far from being at the same level, this is Duan Shaojun's personal opinion.

After watching for a long time, Duan Shaojun carefully hid the Night Pearl and the treasures inside the package.

Next, he was ready to enter the Infinite Arsenal to claim his reward.

Thinking of this, Duan Shaojun gently closed his eyes, and then quickly touched the mysterious light group hidden in the depths of his mind, and suddenly, a familiar mechanical voice sounded again: "May I ask if you want to enter the infinite arsenal immediately?"

"Yes, I'm going to enter the Infinite Arsenal at once!"

Duan Shaojun didn't want to respond, and suddenly, his figure disappeared into the room so weirdly.

Airplanes!......

After a brief blank in his brain, he opened his eyes again, and Duan Shaojun had already appeared in the cabin of the Infinite Arsenal.

At this time, the voice of the robot Long Aotian, which had not changed for 10,000 years, sounded in his ears again.

"Welcome to the Infinity Arsenal again, is there anything I need to serve you?"

Looking at the robot that had already walked to his side, Duan Shaojun didn't talk nonsense, and said directly: "I completed the fifth-level task, and I came in this time to receive a reward." ”

"Yes, sir!"

Hearing this, the robot Long Aotian said respectfully: "Sir, because you have completed the activation task of the fifth-level arsenal, therefore, you can get the opening permission of the fifth-level arsenal once and the upgrade permission of the stealth weapon once, may I ask, what kind of reward are you going to use first?"

Duan Shaojun thought for a moment and said, "Let's upgrade the stealth weapon for me first." ”

After hearing this, Long Aotian nodded and said, "Okay, sir, I'll immediately turn on the munitions virtual projector for you to choose the munitions weapons that need to be upgraded." ”

As soon as the words fell, there was a "boom", and a large number of virtual arms pictures appeared in front of Duan Shaojun's eyes.

There are hundreds of these pictures of munitions, which can be divided into two types of munitions weapons, one is the heavy machine gun of each model, and the other is the light mortar of the various models.

In the pictures of these heavy machine guns, Duan Shaojun saw many world-famous heavy machine guns, such as the domestic Type 77 and Type 89, the American Gatling M134 multi-barreled machine gun, Browning heavy machine gun, the Russian "Rock" series of heavy machine guns, and the Maxim series of heavy machine guns that shocked the world in World War I......

As for those light mortars, Duan Shaojun didn't even bother to look at them.

Nima finally had a chance to upgrade his stealth weapon, who was so full to get a stealth mortar?

The mortar is a thing with a low hit rate and a high attack limit, but more importantly, it can only replenish one stealth shell a day, what is Nima's one stealth shell for?

If the stealth weapon is used, Duan Shaojun will die sooner or later, and the mortar cannot be attacked at close range, and the long-distance attack is all based on ignorance, mainly used to kill and injure a large area of the enemy army.

Therefore, after thinking about it, Duan Shaojun still felt that it was more reliable to choose a heavy machine gun as a stealth weapon.

But if he chooses a heavy machine gun, he faces a great difficulty, most of these heavy machine guns are tens of hundreds of pounds, plus ammunition and tripods, it is even heavier.

Since it is to be used as a stealth weapon, it must meet three conditions: one is to be light in weight, the other is to be strong enough in lethality, as for the three, it is the most important, the range must be long, and the accuracy must not be too bad.

After choosing, Duan Shaojun finally set his sights on the picture of the domestic Type 89 heavy machine gun.

At present, it seems that this heavy machine gun is more in line with Duan Shaojun's basic requirements.

The Type 89 heavy machine gun manufactured by the Great Celestial Empire is a 12.7 mm large-caliber heavy machine gun, the weight of the gun is about 17 kilograms, with a tripod and ammunition, the total weight is more than 26 kilograms, and the ammunition box of the gun is 50 rounds.

At the same time, it has a fast rate of fire, and can fire 400 to 600 rounds in a row within 60 seconds.

What satisfied Duan Shaojun even more was its lethal power, within 1,500 meters, the lethality was absolutely ferocious. Besides, with a weight of more than fifty catties, with Duan Shaojun's current physical condition, he can completely control it.

Originally, Duan Shaojun thought about choosing the Gatling M134 multi-barreled machine gun as a stealth weapon, but the ammunition consumption of that machine gun was too large, and the hit rate was not too accurate, and more importantly, the caliber of the Gatling M134 was only 7.62 mm, and the domestic Type 89 heavy machine gun was a 12.7 mm large-caliber heavy machine gun.

Like the Type 89 heavy machine gun, with a special armor-piercing explosion**, it can penetrate 15 to 30 mm of ordinary steel plates within a kilometer range, if it is used to deal with those so-called Gangqi masters, it is estimated that as long as it is an enemy below the eighth-level Gangqi Martial Sect, it is absolutely a headshot, and the layer of protective body armor on their bodies is estimated to not even be able to withstand the two bullets of the large-caliber heavy machine gun.

As for the Gang Qi masters above the ninth level, Duan Shaojun has not seen them yet, and he doesn't know how powerful they are, so he is not sure whether the heavy machine gun can deal with the Gang Qi masters above the ninth level, but the Gang Qi masters below the ninth level are absolutely killed in groups.

Thinking of this, Duan Shaojun didn't need to hesitate, and directly ordered Long Aotian: "I want this Type 89 heavy machine gun!"

The robot Long Aotian nodded and said, "Sir, you now have two stealth weapons, namely an AA12 stealth shotgun and an SVD stealth sniper rifle, which one are you going to use to upgrade?"

Duan Shaojun lowered his head and thought about it: "Just the AA12 shotgun, in addition to being useful at close range, this thing is far away, it is completely an ornament, and it is better to change to a stealth heavy machine gun if it is in the way." ”

"Okay, sir, I'll upgrade the AA12 stealth shotgun to the Type 89 stealth heavy machine gun for you right away. ”

As soon as the words fell, Duan Shaojun only saw a burst of light in the hand of the robot Long Aotian, and after a while, the light faded, and in its metal palm, a pitch-black and shiny single-barreled heavy machine gun appeared out of thin air.

Duan Shaojun excitedly took the heavy Type 89 heavy machine gun, looked up excitedly and laughed: "Haha, Lao Tzu finally has the legendary heavy machine gun, Nima can only see them in movies and television before, I can't imagine that now Lao Tzu can also carry them out arrogantly, haha, cool, who will dare to mess with me in the future......"

A heavy machine gun of dozens of pounds, held in the hand for a long time, is indeed a bit heavy.

Although Duan Shaojun, who had obtained the stealth heavy machine gun, looked very excited, but after a burst of freshness passed, he casually threw the Type 89 stealth heavy machine gun on the ground.

At this time, the robot Long Aotian asked him what ammunition he needed for the stealth heavy machine gun, and Duan Shaojun didn't think about it: "Give me fifty rounds of armor-piercing explosions!"

After the stealth weapon was upgraded, Duan Shaojun asked the robot again, "How many times do I have the right to open the arsenal now?"

Long Aotian replied respectfully: "Sir, you had eight hundred followers last time, in exchange for one entry access to the second-level arsenal, three access to the first-level arsenal, and in addition, there is also a fifth-level arsenal opening permission rewarded by the system this time, a total of five permissions, may I ask, which arsenal are you going to open now?"
