After lunch, Zheng Fei returned to the station with Mu San, and the troops had a three-day holiday, and then they had to devote themselves to the next stage of training!

"Golden Dragon, I have good news for you, almost all of our brothers here have cultivated their internal strength in the past two days, and there are only three people who have not cultivated their internal strength yet!" As soon as Zheng Fei returned to the station, Yinlong trotted over and said.

"That's really good news; by the way, Yinlong, since the brothers have cultivated their internal strength, and they have basically begun to get started on the way of cultivation, we have to change the next training method; every morning's physical reserve must let the brothers use up their internal strength, and then continue to cultivate in the morning to replenish their internal strength, so that they will grow very quickly, so we will let the brothers start climbing the mountain, because since those who have cultivated internal strength, running on the flat ground has no effect on their physical reserves"!

"What should we do? Are we going to climb the mountain?" asked Yinlong with a look of surprise.

"That's right, it's climbing the mountain, you go and call Lin Feihu, Deng Weichao, Mu San, Dongfang Xing and a few others, let's go to the mountain to explore the way together, and from tomorrow onwards, we will let the brothers start mountaineering training!" Zheng Fei finished saying and put his package in his room, and when he returned to the square from the room, Yinlong and the others were already standing there waiting for him!

"I didn't go, I went to Beishan first, and it looks like Beishan is relatively flat, which is relatively suitable for climbing!" Zheng Fei said and took the lead in walking towards Beishan.

"Jinlong, let's drive to the foot of the mountain, if we walk, it will take half a day!" Because this basin is so big, Yinlong will have to drive after walking a few steps.

"Okay, we'll wait for you here, you go drive, hurry up, it's not long in the afternoon!" Zheng Fei took out his cigarette and distributed it to everyone.

When Yinlong drove the car, everyone slowly walked towards the mountain, the mountain here is completely untouched, no one has walked at all, Zheng Fei and they stepped on the rotten leaves and found a lot of mushrooms, and they are edible kinds, they pick mushrooms as they walk; the trees here are luxuriant, the branches and leaves are intricate, it is very difficult to walk, and there are many wild trees with thorns, so they walk very slowly.

Suddenly Zheng Fei was attracted by a strange tree, this kind of tree is everywhere here, each tree is as big as a person hugging, the bark is all blown up, but there is a transparent film in the place where the bark is exploded, Zheng Fei tried it, this film is very hard, even Zheng Fei's military thorn can't be opened, you must know that Zheng Fei's special military thorn is specially made by the Xiahou family at the top of the world, all made of 10,000-year-old cold iron, sharpened iron like mud, but it can't break this layer of touch!

"Boss, what are you looking at?" Mu San was tired and panting, and came to Zheng Fei's side and asked.

"Mu San, find a way to get the membrane off this tree, I'll be useful!" Zheng Fei said, pointing to the tree.

"No problem, look at me!" After Mu San finished speaking, he took out his military thorn, the military thorn used by Mu San was just an ordinary military thorn, but the steel was much better than an ordinary knife, so his military thorn didn't even want to break the membrane, Mu San had no choice but to cut down the tree, and then peel off all the bark, and then took off the whole membrane.

Zheng Fei's idea today was to observe whether there were any large wild animals on the mountain, such as lions, tigers or something, and then to see if there were any poisonous snakes, but Zheng Fei and they had been wandering around the mountain for four or five hours and had not found large wild animals or snakes, and now they were hibernating, and seeing that the sky had darkened, Zheng Fei and the others turned around and walked down the mountain, and then returned to the station.

After dinner, Zheng Fei took the layer of tree film and cut it with military thorns and burned it, there was no way to take it, the toughness of this film is really good, not afraid of physical damage, not afraid of fire; there is really no way to take it, Zheng Fei immediately came to the square to release the spaceship, and came to the top of the world in the blink of an eye.

"Fei'er, why are you here again? Is there something wrong?" Sima Songzhi was also very strange.

"Mom, I found a strange thing, this kind of thing can't even cut through the thorns, and it's not afraid of fire, but it's very soft, if it can be made into soft armor and worn on the body, then our warriors' combat effectiveness will at least be doubled!" Zheng Fei said with a smile.

"What is it, show it to me!" Sima Songzhi didn't take it seriously.

"No, it's this kind of thing, it's not only soft, but also very light, but the toughness is really good!" Zheng Fei took out the film from the space ring after speaking.

"This, this is the silkworm membrane? Oh my God, how could you find such a thing? Where did you find it?" Sima Songzhi took the membrane and immediately recognized it.

"Heavenly Silkworm Membrane? It turns out that this kind of thing is called Heavenly Silkworm Membrane; there are such trees all over the north mountain where we are stationed, and the bark of the trees has exploded, and it is full of this kind of thing!" Zheng Fei said with a smile.

"Quick, take our people over, by the way, how did you get this membrane down, it can't be that you cut down the tree?" Sima Songzhi hurriedly asked.

"Hey, hey, hey, we tried a lot of ways, but we couldn't get it down, so we cut down a tree!" Zheng Fei smiled embarrassedly.

"You ruined child, this is really a tyrannical thing, the silkworm tree is full of treasures, its bark can be refined to detoxify the pill, the silkworm film is even more priceless, the silkworm tree can make natural spices, and all the mosquitoes and flies will escape when you light it; you wait a minute, I'll go find someone to collect the silkworm film!" After Sima Songzhi finished speaking, he ran away excitedly like a gust of wind; after a while, he brought a large group of people over, and even the flashlight was ready!

Zheng Fei didn't hesitate, he took them directly to the spaceship, and in the blink of an eye, he came to the foot of the North Mountain of the station, and when the people on the top of the world saw the silkworm trees all over the mountain, they trembled with excitement.

"Then you guys take it slowly, I have to go back to rest, I have to lead the team to train early tomorrow morning, I don't know if there are any other three directions, and we haven't gone up yet!" Zheng Fei watched them use a strange method to collect the heavenly silkworm film and prepared to leave.

"You go, wait until we finish collecting the silkworm film and then look for you to send us back, now our chances are much greater, so many silkworm films can make hundreds of thousands of pieces of soft armor without any problem"! After Sima Songzhi finished speaking, he no longer paid attention to Zheng Fei, and watched them collect the silkworm film intently, and Zheng Fei didn't say anything more and turned around and left!

Early the next morning, Zheng Fei asked everyone to carry a weight of 35 kilograms and start jogging, because the people at the top of the world are still collecting silkworm film in Beishan, so Zheng Fei waited for everyone to warm up and then took everyone to start climbing to the east mountain; the mountain here is very steep, and it is also very suitable for training them, but the speed is very slow, and there are still some people at the foot of the mountain for more than an hour! But what makes Zheng Fei happy is that there are also silkworm trees on the mountain in the east, but there are fewer than those in Beishan!

Time is like an arrow, and four months have passed in the blink of an eye, during these four months, Zheng Fei has taken everyone around the mountains and forests every morning, meditated and practiced in the morning, and has been training formations and formations in the afternoon, and the top of the world has also sent more than 200,000 pieces of cold weapons, including knives, swords, axes, spears, and even maces, these weapons are made of 10,000-year-old cold iron, not only very heavy, but also very sharp! Since the weapons arrived, Zheng Fei also told the soldiers not to put down the weapons whether they were eating, sleeping or training, and they had to adapt to the weapons as soon as possible, including its weight, how to use it, and so on!

"Fei'er, come to me!" Zheng Fei had just finished lunch that day when he received a satellite call from Sima Songzhi.

"Okay, I'll be there right away!" Zheng Fei hung up the phone and flew the spaceship towards the top of the world, and in the blink of an eye, he came to the top of the world.

"Fei'er, I have found you a few instructors, they are all very good people who use all kinds of weapons, you bring them back and let them teach you how to use the weapons of those warriors"!

"That's really good, we don't use cold weapons, whether it's knives, swords, sticks, or sticks, we all use brute force to smash them all indiscriminately!" Zheng Fei smiled awkwardly after speaking.

"So, I've helped you find a few masters, by the way, Fei'er, according to the report of our first team stationed on Xiaoyao Island, the time for the demon clan to attack is likely to be advanced, because the sound of drums comes from the gate of hell from time to time, which is obviously the people of the demon clan are dispatching troops!" Sima Songzhi also took a sip of tea after speaking.

"Since it's ahead of schedule, then we're going to fight too, it's all about fighting sooner or later, how about you? Are the people of that legion still not moving after the death pass? And my father-in-law hasn't come out either!" In fact, Zheng Fei's understanding of the affairs of the demon clan is not comprehensive enough, so he can only do everything possible to let all the people survive.

"There is no news yet, you should bring people back first, and let your soldiers familiarize themselves with the weapons in their hands as soon as possible!" Sima Songzhi also sighed, hoping that this catastrophe would end as soon as possible!

Zheng Fei glanced at Sima Songzhi and didn't say anything, turned around and returned to the station with a few middle-aged men in their forties; two of them had knives in their hands, two people held swords in their hands, and several people held maces and iron rods respectively, basically there were two people for each weapon; when Zheng Fei returned to the station, he handed over the people to Yinlong, turned around and got on the spaceship, and returned to his home on Longtou Island.

Zheng Fei returned home, just in time to see his grandfather sitting on the lawn drinking tea, the current Longtou Island is really like spring all year round, and the snow is still white outside, but Longtou Island has always been like spring all year round!

"Grandpa, you're drinking tea, I'm coming back for something, and I'm going to be there soon!" After Zheng Fei finished speaking, he gathered all the people in his family and told them about the demon clan.

"I see, no wonder you've been mysteriously staying in the army to train soldiers recently!" Zheng Fei's grandfather wasn't too surprised when he heard about the Demon Clan!

"I'll open all the formations now, don't go out if you're fine, I'll buy you food and drink for you!" After Zheng Fei finished speaking, he took out all kinds of food from the space ring and put it in the basement, as for the vegetables, he could grow them on the island himself; Zheng Fei arranged everything and flew directly to Xiaoyao Island.
