Zhang Zhen nodded and said, "Then let's cook, after eating, I bought a collar and have to go back and let Lao Hu transform it." ”

Xiao Rong nodded, it was actually too early to eat, and it felt like she was doing it for this little girl, but she didn't dare to speculate on Zhang Zhen's thoughts, so she just went to cook silently.

"Big brother, can I speak?" Zhou Ziyan whispered.

"No, you can't." Zhang Zhen directly refused.

He closed his eyes and opened the chariot system to study the upgrade module, now there are three pieces of black gold, and the whole car is at least seven pieces away from upgrading, this upgrade is related to whether the folding space can be expanded, so be cautious.

If nothing else, the reinforcements of the black crows will inevitably lead to war, and when the time comes, it will be possible to take the opportunity to collect the two towns in one fell swoop even if it is a real foothold, and now it lacks heavy firepower and close defensive weapons.

The problem is that the armament dealers cannot find satisfactory weapons, and the modules in the system are either out of material or not suitable.

"Xiao Rong, do you know how to prevent the chariot from being surrounded by corpses, and what weapons are more effective?" Zhang Zhen felt that he had to start with the existing weapons, after all, the chariot system could absorb weapons and convert them into mod blueprints.

Xiao Rong shook her head and said: "Master, in terms of chariots, Xiao Rong only knows some basic information, and only knows that it is very dangerous for ordinary chariots to be surrounded by corpses. ”

Zhang Zhen sighed, but saw Zhou Ziyan trying to hold up her tied little hands, as if she was in a hurry to speak, so she had to nod.

Zhou Ziyan hurriedly said: "Big brother, I am a chariot technician, and I know what kind of weapons can be used against the besieged corpses. ”

"Oh, let's hear it." Zhang Zhen thought that the little girl might want to go to the toilet, but he didn't expect that she wanted to help.

Zhou Ziyan nodded and said: "For the siege of corpses, the common ones are electric shock shields and cutting gears, but these two effects are not very good, and they are easy to malfunction, and the more feasible is the sonic force field bomb, which can quickly clean up the corpses near the chariot and ensure that the chariot is not damaged." ”

"Feasible? You mean it didn't work out? Zhang Zhen raised his eyebrows.

Zhou Ziyan nodded but said firmly: "I'm sure it's feasible, just have a chariot with excellent enclosure, and then create a sonic concentrating device, the electromagnetic will form a force field, and the sound beam will explode like a nuclear bomb in the force field, which can instantly smash any object, the only problem is that the chariot's defense may have to reach S+ to resist this sonic explosion on its own." ”

"Are there any success stories?" Zhang Zhen leaned on the sand handrail and looked at Zhou Ziyan and pondered, there is indeed an electromagnetic force field in the chariot enhancement module, which is mainly to prevent sound wave attacks, and what the little girl said seems to be feasible.

"Big brother, my proposal was only given a chance by the chief engineer to test, an A+ assault vehicle tested, the sonic bomb exploded successfully, but the assault vehicle was also destroyed, so this proposal was abandoned, but as long as there is an S+ or higher defense capability, this is definitely the best solution for the combat vehicle to protect itself." Zhou Ziyan said with confidence.

"So do you know how much a vehicle can cost at S+ or higher?" Zhang Zhen smiled, this girl's serious appearance really looks like she didn't tell a lie.

"At least 20 million crystals." Zhou Ziyan said seriously: "At present, the material that can pass the S-level defense is more suitable for black gold, a piece of about one million, and it also takes five to six pieces to make an ordinary assault car, and it needs stronger power to get on the black gold, and the motivation can pull six pieces of black gold is not slow, and it is also necessary to use the S-level, which is probably worth 10 million, and then the supporting closed survival system must be there, and there must be a certain weapon, and the frame must also be of S-level quality, and 20 million can only be achieved by refining and calculating." ”

"Well, you know a lot." Zhang Zhen was a little impressed, he thought that this girl had heard it, but what he said was the way, Jiaolong only needs a dozen pieces of black gold because of absorption and fusion, and the utilization rate is high, if it is pasted, it is estimated that it will cost 2o yuan.

Zhou Ziyan said happily with Zhang Zhen and Yan Yuese: "Thank you, big brother, for the compliment." ”

"Don't be happy, your slave collar still has to be worn." Zhang Zhen shook his head, this girl looks really harmless to humans and animals, but the more she is like this, the more she feels uneasy.

However, what this girl said made him confident in this sonic force field bomb, Jiaolong now has S-level defense, and when the black gold is all in hand, SS will not be a problem.

"It's so fragrant, can I eat?" Zhou Ziyan didn't have any worries about wearing a collar, and she didn't even care.

"Go ahead." Zhang Zhen closed his eyes and continued to study the module in the system, the electromagnetic force field remembered that there should be materials when the light flashed at the legion merchant before, and the sonic equipment was indeed checked for a long time and was not found, it stands to reason that there could be no such module, and the system was not unlocked when asked, but the tank should be able to absorb the sonic weapons or devices formed by the device, and it can only be seen whether the armament merchant has it.

Zhou Ziyan happily ran over to eat, saw Xiao Rong help her set the tableware, and hurriedly grabbed the spoon with both hands and scooped it to the beef and potatoes in the bowl.

"Master, her hand ......" Xiao Rong thought to herself that the master had specially ordered the little girl to cook, so she should agree to untie her hand.

"It doesn't affect her eating, don't solve it." Zhang Zhen directly refused.

"It's delicious, it's not mutant beef, what kind of meat is it?" Zhou Ziyan ate one bite after another, but it didn't affect the ventriloquism, and said excitedly: "Is this a potato, I ate a canned beef potato left over from the end of the world a long time ago, it seems to be such a rustling sweet feeling." ”

Zhang Zhen stared curiously at this girl who kept eating but could ventriloquist, and felt that she did understand the chariot, and she refused to say it because of her unknown origin, and she didn't have any fear in front of the zombies, everything was too strange and mysterious.

After the little girl was sure that she couldn't stuff anything into her stomach, Zhang Zhen took Jiaolong and went to the armament dealer.

This time, he didn't bother to talk nonsense with the one-eyed dragon, and said directly: "Electromagnetic force field, sonic energy beam weapons, personal defense weapons." ”

As soon as the one-eyed dragon saw Zhang Zhenlai's hatred, he hated an itchy tooth, so he had no choice but to order the crow to sell it, so he directly called someone to move out two large iron boxes from the hidden room in the back, and then took two gadgets from the shelf behind him, one looked like a ring with rubies, and the other looked like a chocolate bar.

Zhang Zhen opened the box on the ground, there was a layer of bell-like things on top of the electromagnetic force field, and the sonic energy weapon was much larger, it was carried out by two people, and the thing inside looked like a tank battery.

He covered the box and let the two strong men move into the dragon, reached out and picked up the ring in front of the window and put it on his hand, the green shield received the ring information, showing that this miniature laser gun is called snake eye, energy and power are fixed, the point is a hundred, and the continuous use is only sixty seconds, the power point can penetrate the defense of D+, and hitting people is naturally a hole.

"A total of 1.2 million, your one million here is not enough." The one-eyed dragon said coldly.

Zhang Zhen pinched the chocolate bar and shook it, and this thing turned into a small black dagger, and then it became a soft rope, which can be infinitely extended, this thing can be arbitrarily deformed within a certain range, although the essence is like the size of chocolate, but it can be stretched into a prime minister and a long sword, or become a rope tens of meters long.

"Use the money in my town account and deduct it myself." Zhang Zhen curiously played with this weapon called the black snake, this weapon has extremely high toughness, and the control is actually by the snake eye ring, the ring has a small raised point at the end of the palm, this point can control the black snake in the soft and hard state.

"Hopefully this will save your life." The one-eyed dragon said very unhappily after receiving the money, even the sonic weapons and electromagnetic force fields were sold, what kind of armaments is this armaments department.

"Oh, thanks for the concern." Zhang Zhen played with the black snake and left satisfied, originally thought that it would not be easy to find what he wanted, but he didn't expect it to be so smooth, these two small weapons can be very useful in reality, because they are hidden enough.
