"Heina! I thought I'd never see you again! As soon as the door opened, a pink-haired female gnome burst out of the shelter and hugged Haina and cried.

"Alright, Penny, everything will be fine." Heiner patted Penny on the shoulder and whispered comfortingly.

It seems that these two people may not be able to pay attention to themselves in a short time, so Lin Wen simply took out the communicator and tuned to the whole channel to ask about the situation of the other teams.

"This is a team, we have arrived at the shelter, how are the other teams, are there any casualties?" Lin Wen said to the communicator.

"The second team injured one person and is in good condition."

"There were no casualties among the three teams, and the new weapons are so easy to use."

"The four teams injured two people, and these two fools went off and injured themselves!"

"Five teams ......"

After the report, Lin Wen was very relieved to find that none of the more than 100 mercenaries were injured except for a few wounded, and there was no doubt that this was all thanks to the weapons that were distributed before the mission began.

"Very good, everyone has worked hard, now let's come to the shelter and rest for a while." Lin Wen hung up the communication after speaking. The Vault is a city within a city built by the gnomes, and in addition to the more than two hundred gnomes hiding here, the remaining space is enough to cram all the personnel of the Extreme Force in Shattered Mine City.

"Heina, I'm curious how you managed to get this group of foreign aid, I remember you didn't leave with anything at that time." After Heiner and Penny poured out their feelings, Penny asked Heina a question that she had been holding back in her heart.

The gnomes in Shattered Mine City are more homely, and they won't leave their city if there's nothing to do. But Penny is different, as a young man she attended the Construction Machinery Institute in the dwarf city of Nomorigen for ten years before marrying in Shattered Mine. She also knew how much it would cost to hire a well-trained team of mercenaries to carry out a city support mission, and Penny was afraid that Haina would promise an unacceptable price to hire these mercenaries, so that Shattered Mine City could be said to be out of the wolf's den and like a tiger's mouth.

"Uh......" Hearing his wife ask, Haina didn't know how to answer for a while.

"Metal, construction machinery, you pay for the materials produced in this city." Lin Wen walked over and said, "In addition, we need your best mining and engineering professionals to work for us for two years, remember, it's work." ”

"Is what he said true?" Listening to Lin Wen's words, Penny looked at Haina with doubts and confirmed.

"Yes, it's true." Heiner nodded. "What's wrong? Are they asking too high? ”

"No, it's too low." Penny turned her head to look at Lin Wen: "Kind stranger, I thank you very much for your help, but I want to know, what is the purpose of your offer such a low price?" ”

It's so fresh! There are still people who think it's cheap to buy things these days!

"To each his own according to his needs." Lin Wen shrugged, "Our mercenary group is now in a period of development and needs a lot of resources, and it just so happens that these things can be provided by your Shattered Mine City. Let's say metals, all kinds of machinery. We want mining trucks outside, and we want engineering workshops to make mining trucks. If there is something we are more interested in, we can also buy it with gold. ”

"I'm sorry, it looks like I misunderstood you." Penny said, "If you can solve the current problems for Gravel, I'll be happy to serve you for two years. ”

"Penny is the best master of mining in Gravel City, and the second best master of engineering after me, and I think you will be satisfied." Haina also said at the right time.

"Hey! I'm the best engineering master in Gravel City, okay, you're the second! Listening to Heina's words, Penny couldn't help but argue with her husband.

"I invented the hot wire gun, so I'm number one!"

"The hot-wire gun can't be eaten, and it can't even penetrate the skin of a caveman, so what's the use of this thing?"

"Useless? What do you cut steel plates with? Tear it by hand? ”

"Ahem!" Gnomes naturally like to quarrel, and the closer they are, the more fierce they become. Seeing that the couple was getting more and more noisy, Lin Wen couldn't help but cough twice, "Haina, show me your hotline gun, I'm curious." ”

"Oh, okay." Listening to Lin Wen's words, Haina subconsciously took out his weapon, but retracted it before handing it to Lin Wen, "I also want to see your weapon, let's exchange it." ”

Heiner smiled shyly.

"No problem." Lin Wen took the MK17 battle rifle from behind his back and handed it to Haina, and then took the hot wire gun from Haina's hand. The appearance of this gun when attacking is exactly the same as the laser guns in those games and film and television works before the crossing, and Lin Wen has long been itchy about it.

With the help of Godcraftsman-level engineering, Lin Wen easily disassembled Haina's hot wire gun, only to find that the structure inside was very simple - a finger-thick high-quality ruby, a bowl-filled engineering device, and a translucent energy source that looked like a No. 5 battery and emitted green light.

Fortunately, no one was reached.

This is clearly the simplest ruby laser generator, a strong enough light source into the ruby, so that the ion flip density reaches a threshold, and then a laser beam can be ejected. This weapon is quite primitive and crude, but this small energy source is the key to the whole weapon.

The main factor limiting the emergence of high-tech weapons before the crossing is energy, the earth can create a laser that penetrates the material of a white dwarf, but because there is no small enough energy source with high energy density to make a simple laser pistol, I have to say that this is really a helpless thing.

"Heina, did you make this?" Lin Wen pinched the energy with his thumb and forefinger and asked Haina and Penny.

"That's right, it's called the Crystal Source Battery, and it's something we use to power weapons and vehicles." Haina looked back at the things in Lin Wen's hand and said, "The piece in your hand is enough for my hot-wire gun to shoot a hundred times, and this thing is also used in the mining cart outside, but the volume in the mining cart is relatively large." ”

"Are there any drawings? I bought the structure diagram of this thing. "Small energy with high energy density! What Lin Wen lacks most now is this thing, and with this thing, there is no need to worry about level 40 equipment.

"For the sake of the friendship between the two of us, I'll send you well." Haina took out a design drawing from his backpack and handed it to Lin Wen, who took a closer look and found that the raw materials of this thing were actually high-purity crystals and magic crystals, and the amount of energy in the battery was directly proportional to the volume of the battery and the level of magic crystals.

At present, there are also items that use magic crystals as energy in the Acala continent, for example, the tactical flashlight attached to Lin Wen's MK17 rifle is stuffed with a pale crystal as an energy source, but if the pale crystal is replaced with a white quality magic crystal, then the brightness and duration of the flashlight will be increased by three times, which is the biggest feature of the crystal source battery.

As far as Lin Wen is concerned, with this drawing, this mission is no longer a loss.
