Gu Tie felt scared when he remembered the devastating bombardment in the previous battle. But when he thought of his ability to have such terrifying firepower, he was so frightened that he was so happy. But Lan Long shook his head and said in a deep voice: "There are many problems. First of all, the railgun requires a lot of electricity. This guy must be used." He pointed to a large box in the pile of parts: "I probably took a look. This is a proton fuel cell. The name is a battery, but it is actually a power plant with strong power. It burns a special fuel and outputs strong electricity, so that the railgun can fire hard..."

Hongshi quickly coughed: "In short, without fuel and electricity, the railgun is scrap iron."

"In other words, if we want to use rail guns, we must first have fuel?" Gu Tie asked.

"Yes, first of all, there must be fuel. Secondly, there must be bullets. The rail cannon is a monster with tens of thousands of bullets per second..." Lan Long opened another metal barrel to reveal the neatly arranged fine needles inside. These fine needles are only three centimeters long and very thin. There are some fine bumps on the surface, and the process is very fine. This metal barrel is larger than an oil barrel, and it is full of such needles inside.

"It's these little things that instantly tear apart apart apart?" Gutie picked up a needle and weighed it. He found that it was much heavier than it looked, almost as fast as a small-caliber bomb. It was estimated that the material was a super high-density heavy metal. Blue Dragon gritted his teeth and said, "Don't look at it as small, once it was accelerated by the rail gun to more than ten times the speed of sound, its kinetic energy was even more fierce than that of a large-caliber sniper rifle bullet. Ordinary rail guns can accelerate the needle bullet to ten to fifteen times the speed of sound. It is very thin, and the thinner it is, the smaller the air resistance. So it also has a terrifying lethality at a long distance. The fucking thing is. The rail gun is not a firing needle bullet one by one."

Gu Tie recalled the destroyed houses and continued: "A lot of rail guns fired at one time?"

"It's not that it's a lot of fire at one time, it's that it's always tide... it's a lot of sprays." Lan Long patted the rail gun's barrel and cursed: "This bitch spreads his legs with one splice. The electromagnetic field will continue to take effect and will work continuously. The supply chain sends needles into the rail gun's cabin like a tap water pipe, and the rail gun keeps spraying needles like a high-pressure water gun spraying water."

Gu Tie sighed, "I understand why the building shattered in the blink of an eye."

"Mr. Tie, look." Lan Long patted the inner wall of the cartridge: "We all remember that the power armor only fired twice, once destroyed our Katie, and once chased Tie Ye to shoot. The two times combined didn't last long. But you can see how much needle shots consumed. It took about a quarter of the time, and two shots combined for less than three seconds, and it took a quarter of it."

"I understand that the faster the firing rate, the more bullets you consume." Gu Tie said.

"I'm not afraid of more bullets consumed, but I'm afraid of the difficulty of supply." Lan Long picked up a needle bullet: "The principle of a rail gun is electromagnetic acceleration, so magnetic materials must be used. The better the magnetoelectric performance, the better the acceleration performance. But ordinary magnetic materials, such as steel nickel, are too soft and too brittle. Real rail gun needle bullets are specially made super heavy metals."

"We can't get this kind of needle bullet?" Gu Tie asked.

"It should be available, but I estimated the price. The cost of using killing is definitely much higher than the bonus of the man." Lan Long cursed: "But players who can use power armor are all rich people raised by bitches, and they won't care about the bonus of the man when they are in war. For example, this orbital cannon costs at least 700,000 to 800,000 star diamonds, and this barrel of needle bullets, it is estimated to cost 200,000 to 300,000 to 200,000 to 300,000 to 200,000 to 300,000 to 200,000 to 200,000 to 200,000 to 200,000 to 200,000 to 200,000 to 200,000 to 200,000 to 200,000 to

Gu Tie was stunned and said, "This barrel of needle costs 200,000 to 300,000 star diamonds?"

"Yes. This kind of superheavy metal alloy with high magnetic sense is very high-end thing," said Lan Long.

Gu Tie was silent for a while before saying, "It seems that if you use it to kill people, you really have to worry about the money. Is there a third problem?"

"Yes, who assembled this pile of rags?" said Blue Dragon. "It still has a lot of fuel and bullets left, enough for one or two."

"Can't you?" Gu Tie asked.

"I..." Lan Long said self-deprecatingly: "It's okay to ask me to repair a motorcycle, but the rail gun is too technical."

Gu Tie looked at the robin again. The little guy was touched by Gu Tie a few times and was getting much better. He was roasting bugs with a sandstorm. She turned her head to look at the rail cannon and said softly: "I know the principle of the electromagnetic rail cannon. If there is a technical diagram, you can compile a program for Patty to assemble and transform..." She pursed her mouth tightly and looked at Gu Tie with her big watery eyes. This made Gu Tie helpless. Everyone else knew what happened to Patty, and they all showed a laughing and crying expression. Patty was round, thick and clumsy, and it was not convenient to transfer quickly, so Gu Tie dismantled Patty into a pile of parts and stuffed it into a travel storage box.

If you want to have an engineering robot Patty, you must first have a mobile vending machine, but Hongbai doesn’t know when will it come?

Gu Tie frowned and asked, "It seems that the rail cannon cannot be used for the time being?"

"That's right for the time being." Lan Long said.

"Then what did you say just now, 'Catch a robot and install it'?" Gu Tie asked.

"Isn't this a beautiful wish?" Lan Long said with a smile.

Gu Tie sighed and said with a smile: "Okay, put the rail cannon aside first, let's talk about how to fight next."

For a moment, no one was talking in the room, and everyone was in deep thought, with only the bonfire making some crackling sounds from time to time. Blue Dragon had five magazines of sniper rifle bullets, enough to deal with one or two battles. After all, snipers were focused on hit rate, and the bullets were not consumed much. The darts of the sandstorm had not been used, and it was enough to use one or two times. Maggot had twenty-six magic cannons left, which was enough to use the last time. Redstone's ammunition was not left, but he himself was a big killer. Xiaotang's equipment was quite complete and he could participate in the battle. Gu Tie's seal arm guard had not been used, and it was full of bullets, which was enough to do one or two games.

On the surface, the Five-Headed Dragons still have a certain combat power and can cope with a small-scale battle of one or two times. But in fact, the Five-Headed Dragons can do nothing. The remaining ammunition needs to be kept to deal with emergencies and cannot take the initiative to seek war. If they go out to fight overnight, they will have no ammunition left. But they encountered a monster on the way back...

Gu Tie calculated the ammunition and said with a smile: "Everyone have a good rest tonight, maybe the red and white will come in the middle of the night."

"Haha, I'm so tired today." Hongshi said with a smile.

"I'll go out to find some food. Is there anything special about your recipe?" Gu Tie asked.

Lan Long was so scared that he trembled and said quickly: "Please have a good rest, and leave this small matter to us."

"Yes, Master Tie, you are the leader of the group. I will leave such a small matter to us members." Hongshi said.

"Hey, you said just now that you were so tired?" Gu Tie said.

"That's just a small matter. The great thing is right now, and such small matters are ignored." Hongshi said in a deep voice.

"What's the point?" Gu Tie asked in confusion.

"No. This is righteousness, people regard food as the sky, this is the way of heaven." Lan Long hurriedly quoted the ancient Chinese sayings that Gu Tie once said today.

"Uh..., you guys are very weird." Gu Tie said.

"It's nothing. Master Tie just eats bugs here, and leave the hunting activities to us." Lan Long said with a smile.

Gu Tie couldn't resist the two nervous strong men, so he had to let them go hunting.

……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

It was getting darker and in the dilapidated house, Blue Dragon was demonstrating how to use gunpowder to quickly remove hair. - Previously, Redstone, Blue Dragon and Xiaotang went out to hunt. They got back dozens of birds as big as roosters. Bird meat is indeed a delicacy, but it was troublesome to pluck hair, so it was Blue Dragon's turn to demonstrate various armed hair plucking. Method 1: Blast hair plucking. Mix clay and ** into a thin mud and apply it on the bird's hair. Let the bird's hair be fully mixed with the mud, and then burn it on the fire. The mud mixed with the ** and bird's hair will explode after drying. The bird's skin will be fried to a crispy state, and the bird's hair will fall off all over the floor. Method 2: Pull the hair from the fuel oil, mix the fuel oil of the mud sprayer with the clay...

Hongshi, Xiaotang and Maga were all watching Lanlong's cooking performance, staring at her eyes wide open. In front of another small campfire, Gutie was cooking mushroom soup with sandstorms and robins grilled larvae. These bugs looked fat and white, and after grilling, they turned golden, some like KFC and McDonald's fries. Gutie picked up a bunch of golden bugs and gently pinched one of them. It felt like the bug was quite hard, like cooked egg white. He pulled off one of the bugs and put it in his mouth and chewed it for a few times, then nodded in satisfaction. The bug tasted a bit like chicken sausages on the earth, but it was very chewy and the protein content was very satisfactory.

"It's already possible to eat it." Gu Tie handed the grilled insect skewers to the robin and said with a smile: "High protein pure natural food."

The robin picked a bug and looked carefully, just like a chicken that discovered an earthworm for the first time. The sandstorm seemed a little nervous and said uneasy: "If you don't want to eat, don't need to..." Before she finished speaking, the robin stuffed the bug into her mouth, then squinted her eyes and chewed it. After a while, the robin swallowed the bug, opened her eyes and nodded and said, "It's delicious and nutritious."

"Then eat more." Gu Tie handed the robin to the robin, picked up another robin, and tried one first, and then handed it to the sandstorm. The robin was hesitant to hold the robin, but when she saw the robin who was happy to eat the robin with relish, she became competitive. She couldn't compare with Gu Tie, and could she not compare with the robin, so she clenched the bullet and picked a worm and stuffed it into her mouth.

To be honest, she regretted it after the insects entered her mouth. There was always a sense of terrifying feeling of insects coming alive and crawling in her mouth. She bit her teeth and found that the taste was not very bad, but it was a bit bitter, with some strange fishy smell and sour smell, and her gums were a little itchy. She wanted to vomit, but she chewed and swallowed hard under the encouragement of vanity.

After a while, she finally finished eating the skewers and said with a sense of accomplishment: "It's finished."

"Thank you for your hard work." Gu Tie sent a bowl of steaming mushroom soup.

The sandstorm took the mushroom soup and found that the robin was holding two skewers of grilled bugs, with one skewer on each of his left and right hands, and was eating a slim bite with delicious taste. Two empty wooden sticks were placed obliquely beside her knees, indicating that she had eaten two skewers. The sandstorm had lost his sense of accomplishment just now, and he was full of frustration and unwilling challenges. He reached out to Gu Tie and said, "Come on, three skewers."

Gu Tie pulled out three skewers of the bugs that had just been grilled and handed to the sandstorm, and said with a smile: "Everything is here, you can eat it slowly, I'll go out."

The sandstorm was full of fighting with the robin, so she didn't ask what Gu Tie was doing. If Gu Tie was excreted, it would be so embarrassing. In this way, the two girls continued to eat grilled insects, and Gu Tie left for a while. After a while, the robin ate seven skewers and the sandstorm ate nine skewers. This made the sandstorm secretly relieved. Now the insects are gone, and the outcome is definitely destined.

"You guys eat so fast, but fortunately I speed up."

Gu Tie came back with a heavy bag and put it on the bonfire, revealing a bunch of strange insects that had been twisted away. The sandstorm's expression became very stiff, but the robin opened his eyes happily, just like a worm eating delicious food, and fell in love with the chicken that was very excited to see the earthworm. She said sweetly: "Mr. Tie, can all these be eaten?"

"I can eat it directly. You can scan it with the museum encyclopedia first." Gu Tie said with a smile.

The sandstorm suddenly remembered what he had just ignored, and his expression suddenly felt a little uncomfortable. The robin tilted his little head and thought for a while, shook his head and said, "I don't have a museum encyclopedia." This surprised Gu Tie and asked in surprise: "Then did you eat so much just now?"

"It's delicious, I like to eat it." The robin said crisply.

Now it was Gu Tie's turn to worry. The robin didn't use the Encyclopedia to scan for toxicity, so he ate a lot of insects. Will there be any problems with eating? But she was obviously not full, and was staring at Gu Tie's newly caught insects, and her pink little mouth couldn't help but pursed. Gu Tie had to ask: "Did you feel the strange smell when you ate it before, which is spicy, bitter, etc."

The sandstorm suddenly seemed even more uncomfortable, but the robin shook his head and said, "No, it's delicious."

Gu Tie breathed a sigh of relief, picked up a bug and skewed it on the wooden sign, and said while busy: "You must pay attention when eating next time. Our tongue can automatically distinguish food. Things that are good for the body will feel delicious and make people eat more. If you feel uncomfortable, it is a warning, so bad things are often harmful to the body."

"Well, I understand." Robin said seriously, with his big eyes staring at the insects on Gu Tie's hand.

Sandstorm regretted it very much, regretted her impulse, and regretted her awkward emotions. She had only one idea now, which was to immediately find a corner outside where no one was, and then vomited wildly, spitting out all the things she had just eaten. It was known that the robin picked up a bug that looked like a spider and said to Sandstorm: "Sister Sandstorm, this is for you to eat."

The sandstorm took the bug and told her to answer this 'I'm sorry, I can't eat it anymore, I'm going to vomit'. But her vanity made her unable to speak, and she forced herself to smile and said, "Okay, let's see which of us eats more."
