"This?" Seeing that her brother handed over the ball-like thing in her hands, Fourteen Niang didn't know what it was, but it was hard and made of iron.

Don't go, you who say vibrators, have you ever seen a vibrator made of iron? It's not a toy, and if you accidentally press it in the wrong place, you can kill someone.

"This is Maozi's RG60TB thermobaric grenade, come, pull here and let go of this thing, and then throw it out with your greatest strength, remember, the whole action should be fast, no more than two seconds."

Although she didn't know what Maozi was, Fourteen Niang still followed Xia Yu's instructions and threw the balls in her hand in the direction of the cliff.

Such a small thing is smaller than the mana ball condensed by the rainbow transformation technique just now, it shouldn't be very powerful, I have no concept of grenade fourteen niang, let alone thermobaric grenades.

"Boom~~~" This sound cannot be described by the sound of an ordinary grenade exploding, and the fire rose into the sky seventy meters away, but in a few seconds, the scorching temperature spread to Xia Yu with the shock wave.

Although there was no lethality here, the temperature made Fourteen Niang swallow a mouthful of saliva, so she could already imagine what it would be like to be in the center of the explosion.

The firelight cleared, and a huge crater was exposed.

The RG-60TB thermobaric grenade is loaded with 70 grams of cloud explosive, the explosion yield is equivalent to 550~660 grams of TNT explosives, and the explosion power is equivalent to 10 ordinary grenades, which is already the most powerful grenade that Xia Yu can find on the market.

In the past, those offensive grenades Xia Yu dared to detonate at close range with the enemy, but they also had to pay the price of broken bones and deafness, and if they were replaced with RG-60TB, Xia Yu felt that he would have to be resurrected once.

"How, this grenade is filled with thermobaric explosives - cloud burst agent, the killing radius reaches 17 meters, and after the explosion, an overpressure shock wave is quickly formed within the killing radius, and then it will burn off the surrounding oxygen, so that the surviving enemy suffocates to death, in fact, it is better to use in a narrow indoor environment."

This is the first lesson that Xia Yu wants to teach to Fourteen Niang in the real world, "Human wisdom can crush spells in many cases, and if you replace it with a powerful one, even the gods will still blow it up for you." ”

This is not false at all, but what you want is also to attack it unprepared, otherwise you don't want to run away before the nuclear bomb is launched, just like the low-level wild god snake god in the ghost blowing lamp plane, he wants to use the unbounded demon pupil, then all dangerous explosives can be transferred to the imaginary space before exploding, and the damage will be transferred.

But the lethality alone is enough for Fourteen Niang to be shocked.

"Click~~Click~~" Listening to the voice next to her, Fourteen Niang turned her head over, only to see Xia Yu pry open the two wooden boxes with a crowbar.

"It's not easy to get this thing even if you have money, there are still two boxes here, minus the one you used, and twenty-three, all of them are for you, but you also have to use different types of grenades according to the situation, look, here are all other grenades, from different countries."

Xia Yu waved his hand, and the more than 30 wooden boxes built up next to him were of different colors and styles, and the grenades contained in them were naturally different. Since you want to train Fourteen Niang as your own fire support, grenades are naturally indispensable.

"Thank you, brother." Fourteen Niang, who came back from the shock, heard Xia Yu's words, and her joyful expression was directly revealed, she naturally liked these weapons very much.

Xia Yu is still very pleased with the appearance of Fourteen Niang, it seems that he is still very talented in education, if it weren't for the poor grades that year, maybe he would have applied for the teacher.

If there were bystanders, he would definitely point to Xia Yu's nose and let him pull him down, what would he teach? Throwing and using grenades, medium and long-range precision sniping? Don't go and harm the flowers of the motherland!

In this way, Xia Yu took out a class of weapons and carried out a one-on-one elite education that combined theory and practice for Fourteen Niang.

In this northern land, fires and explosions often sound, but no one can find out in this place where only birds, after all, there is only Xia Yu and one demon here.

As for the craters left on the ground and on the mountain, it was quite easy to solve, and Xia Yu destroyed all the traces of these battles after dozens of careful directional blasting.

After more than half of all kinds of weapons were consumed, Xia Yu also ended this teaching mission, not because he was afraid of how much "military spending" would spend, but after coming out for so many days, Xia Yu had not forgotten his other purpose of coming here.

Looking at the fourteen Niang Xia Yu who was sitting on the edge of the tent holding the Sprite he rewarded and drinking, he said: "Fourteen Niang, your body is a fox demon, so how about your ability to dig holes?" ”

Foxes generally live in the cave, although their family lives in the ancient temple after turning into a human form, but there should still be a legacy left from the bones from generation to generation, you don't see Xuanyuan Tomb has become the fox spirit's nest, how did they get in? Of course, it was made through a hole.

"It's okay, when I was a child, Fourteen Niang liked to dig holes and play." Saying that, Fourteen Niang put down the can in her hand, and when she stretched out her hands, they really turned into small paws, which were covered with snow-white fluff like her little ears.

Xia Yu shook his hand, well, the pink meat pad is very comfortable, but this is not the point, Xia Yu continued to go deeper, but touched the sharp claws hidden in the gap between the meat pads.

"Fourteen mothers, bright paws."

"Choking~~" A piece of saber in Xia Yu's hand was directly pierced by the tip of the claw stretched out by Fourteen Niang.

This claw can cut gold and jade!

Fourteen Niang was a little embarrassed to be grabbed by her brother like this, but Xia Yu didn't notice this, but continued:

"Fourteen Niang will give you a very important task in the next few days, we are going to build a big home under this ground, so I will draw an area, dig as deep as you can, take these things to collect some soil samples below, and we will split up to see if we can find a suitable place."

"No problem, brother, but why build a home underground?" In the real world, Fourteen Niang has already seen Xia Yu's two homes, and she is a little curious about Xia Yu's big home underground.

"Because, my brother has something too powerful in his hand that must be hidden, so that no one else can know, you know, some people are more terrible than those monsters and ghosts that we killed."

Xia Yu said the facts in another tone, and this is indeed the case, it doesn't matter what Xia Yu thinks about such a thing, what matters is what the person in power will think, although Xia Yu has nothing to worry about in the real world, he doesn't want to live a dark life.
