After leaving Gutaiguan, the surrounding mountains gradually decreased, and soon came to the endless prairie.

Fang Yan saw the grassland for the first time, although he had seen a lot of grassland pictures on TV in his previous life, but he did not have the opportunity to travel to the grassland, after coming to this world, it was also the first time to see the grassland, the endless withered grass continued to the sky, if it was not for the fact that he had not gone deep into the grassland, there were mountains around him as a reference, he would also wonder if he would have lost his way.

After entering the prairie, the five of them walked until the evening, but they did not encounter half a figure, giving people the feeling that it was like being deserted in the grassland.

"Feng Bao, where have we gone?How far are we from the nearest barbarian tribe?" After walking for a day without seeing a figure, Lin Feng felt a little disoriented. "On this prairie, everything looks exactly the same, and I can't tell the direction. ”

Fang Fengbao looked at it with an abstract picture, compared the surroundings, and looked up at Tiandao: "It's also the first time I've come to Guanwai, how do I know where this is, besides, the barbarians are all nomadic on the grassland, God knows that they will migrate in that direction." ”

Senior Sister Hu suddenly spoke: "I want to set fire to this grassland, this place is full of wild grass, and the spark can start a prairie fire, you say, what will happen to the barbarians then?"

Feng Yu and Lin Feng's eyes lit up, and they both felt that this was a good idea, and they had a lot of ideas for doing it.

Fang Yan said: "It's too early to set fire, we have to find the Jiuqu River first, and then we can set it on fire." ”

Senior Sister Hu heard something from Fang Yan's words and asked, "The task given to you by the general must not be only arson, right?"

Fang Yan didn't speak, and Feng Yu also asked: "Fang Yan, we are all our own people, and there can't be barbarians and spies here, what can't you say." Even if the mission is dangerous, everyone is out of the customs, and even if you want to go back, it is impossible. ”

Fang Yan glanced at a few people and continued to hurry: "What will happen if you set fire to the grassland?"

Feng Yu thought for a while and said: "The grassland is burned, winter is coming, it will definitely snow in this northern land, and in the spring of the next year, the grass will grow again, and the barbarians will definitely prepare grain and grass for the winter." The only thing that can affect may be the demon beasts on the grassland. ”

Lin Feng added: "The further north you go, the colder the weather becomes, and the demon beasts should also hibernate, and this fire, those who are asleep on the grassland should also wake up......"

Fang Fengbao interjected and added: "I know, it's a beast tide, there are wild grasses everywhere, if a fire is burned, all demon beasts will definitely be driven away by the wildfire, and the nest may be burned, and the beast tide will definitely be triggered at that time." ”

Senior Sister Hu shook her head thoughtfully and said: "Even if you burn the grassland, the demon beasts on the grassland are mainly the fifth-level demon beast gray wolf, although there are a lot of them, but these demon beasts can't affect the main army of the barbarians, our task this time should be to stop the barbarian army from going south, even if it can't be stopped, let them lose their troops." ”

Fang Yan glanced at Senior Sister Hu with some surprise: "It is worthy of being a father and daughter, and they all have similar ideas." The first point of our mission this time is to set fire, drive away the gray wolf to cause the beast tide, as Senior Sister Hu said, the purpose is so simple, how to do it, it all depends on our own play, my idea is to do one without doing two endlessly, come to one pot end, along the Jiuqu River, to the black water and white mountain.

Didn't the barbarians say that the Jiuqu River is the root that gave birth to the grassland, I want to destroy this river, once and for all, directly let this grassland no longer support barbarians, and by the way, let the earth dragon come out for a walk, I remember that thing seems to have slept for many years, and it should be hungry. ”

Everyone was a little surprised when they heard what Fang Yan said, if they didn't know that he didn't like to talk big, maybe they would have wondered if he was delusional.

"Don't look at me like that, don't believe it's okay, you will believe it soon, if it wasn't for Feng Bao to hear the news, I wouldn't dare to think so. Fang Yan was smiling and confident.

Fang Fengbao asked puzzledly: "Brother Yan, I have heard a lot of news, I don't know which one you are talking about?"

"The barbarians have found oil under the black water and white mountains, oh, what you call black fire oil. Although Fang Yan knew very well what kind of impact his plan would have once it succeeded, and the heinous sin was not enough to describe, he didn't feel it at all, as if he was just treating it all as a game.

"What can black fire oil do? set fire to the mountain?" Fang Fengbao didn't understand. "Could it be that you can use the black fire oil to burn the black water and white mountain, and then trigger an even bigger beast tide?"

"The earth dragon is sleeping under the black water and white mountain, maybe this black fire oil can wake it up, it is relatively troublesome to set fire to the mountain, but it is not impossible, the only question is, how to destroy this Jiuqu River?" Feng Yu analyzed, and couldn't understand how to destroy the Jiuqu River.

This is the limitation of thinking, Feng Yu will never understand the problem of oil pollution, nor will he know the problem of soil erosion, let alone the dangers of desertification.

Hurrying in the night, everyone relied on the stars to distinguish the direction, all the way forward, until midnight, Lin Feng suddenly stopped, and carefully sensed the surroundings: "The water vapor is a little heavy, maybe there is a water source around here." ”

"That's to the Jiuqu River. Fang Yan also sensed carefully to determine the direction of the Jiuqu River, and those who didn't know the way could only rely on the Jiuqu River as a reference when walking on the grassland, so that they could distinguish the direction clearly.

"Found it. Senior Sister Hu said, running quickly to the right, and everyone hurriedly followed, and after a while, they came to a river ten zhang wide.

Fang Yan washed his face and camped on the spot and said, "Rest first, find the Jiuqu River, and the rest of the road will be much easier." ”

"Don't light a fire at night, on the territory of the barbarians, we better be careful. Senior Sister Hu reminded and cleared out a piece of land.

The five of them walked for a day, and they had to hurry early the next morning, so they all rested quickly, so as not to delay the next day's trip, naturally, the five people chose to meditate instead of sleep, even Fang Fengbao was no exception, he was also forced, if he didn't work hard, it would be too hard to carry the dragon slaying knife.

There was nothing to do all night, and in the early morning of the second day, Fang Yan faced Dongfang early to breathe out and practice qi.

When the sun and moon converged, the sun had just shed its first rays, and a purple gas flew from the east along the sunlight and happened to fall on Fang Yan.

This is exactly what the Taoists say about the purple qi coming from the east, and the purpose of collecting qi and practicing qi is to harvest and practice this purple qi, but cultivation determines the ability to collect qi. This wisp of purple qi was the key to whether or not Fang Yan was extremely Tailai at this moment.

With the help of the purple qi of heaven and earth, and then supplemented by the vitality of the rising sun, under the sympathy of heaven and earth, the true qi in the body boiled up in an instant, and a qualitative change occurred.

The morning sun rises slowly, and when it is fully raised, the spiral true qi finally completes the final transformation, the two qi of life and death evolve into a simple yin and yang two qi, the true qi changes, the foundation building is completed, the gong is completed, and the subsequent exercises can finally be further practiced.

"Haha......" Fang Yan got up and laughed, facing the rising sun, he had an impatient mood, wanting to let noon come soon, so that he could collect the sun's qi from the heaven and earth to the sun.

"What's the matter, so happy?" Senior Sister Hu seemed casual, but she had a heart.

Fang Yan said with a smile: "It's nothing, it's just that the foundation is completed." ”

Feng Yu walked to the river to wash and said, "You work hard enough, and you work so hard to build the foundation, I don't have the patience as good as you." ”

"You and Lin Feng have already cultivated to a high level, although there are many promotions in the Taiwu Secret Realm, they are not like me, if you don't lay a solid foundation, it will definitely have an impact in the future. Fang Yan didn't want to talk nonsense on this issue either, so he said instead. "I'm going to catch fish, I'll be there early. ”

"I'll help you. Senior Sister Hu said and followed.

On the pristine prairie, the Jiuqu River is crystal clear, the river level is gentle, and there are many fish and shrimp in the water.

After eating the grilled fish, the five of them cleaned up the traces, and immediately went on the road, discerning the direction clearly, and headed towards the black water and white mountain.

As noon approached, Fang Yan stopped, cleared out a piece of grass, carved the formation, placed the spirit stones, and prepared for cultivation.

Lin Feng and the others didn't know what he was cultivating, and they watched curiously.

When noon came, since it was winter, the power of the sun was naturally greatly weakened, and because of this, Fang Yan was more sure, if it was summer, he would also worry about whether he would be burned to ashes by the power of the sun's true fire.

Practicing Qi is the so-called external service and internal training. Regardless of whether it is the qi collection method given by the Zhi Brain, or the people of this world who practice qi, they are actually collecting qi, but everyone is collecting spiritual energy to practice, and the advanced point is to collect special spiritual energy between heaven and earth.

Relatively speaking, the most abundant and easiest to obtain in the world is the sun and moon qi, that is, the power of the sun's true fire and the power of the Taiyin Xuanbing, which can be obtained everywhere day and night, but few people will choose these two kinds of yin and yang qi, which are the most common in the world and the world, just because although these two qi are easy to obtain, they are also extremely dangerous, and there are only a few who can use them.

When noon came, Fang Yan sat in the simplified magic circle and immediately collected the Sun Gang Qi as requested.

As soon as the exercise turned, in an instant, Senior Sister Hu and everyone who were watching suddenly felt that the light was dim, just like the sun hiding in the clouds, but the sun in the sky was very conspicuous, but the sunlight nearby was inexplicably reduced, and I don't know what was sucked away.

This change was only over in a moment, everything returned to normal, but the formation on the ground collapsed directly, all the formation foundation spirit stones turned into powder, Fang Yanpan sat on the ground, motionless, faintly, everyone felt as if his body was burning, but they couldn't see the flames, and there was no harm.

With the help of the power of the formation, combined with the method of gas collection, the sun gang qi is gathered, and the sun gang qi is breathed and breathed, and the sun gang qi enters from the nostrils, because the sun is rigid and turns left, so it only enters from the left nostril, and the right nostril is the way of the Taiyin Gang qi.

Sun Gang breathed into his nose, and in an instant, his nose and throat felt a burning pain.
