Shi Guoshi served as a national teacher for several years, during this period, he supported many ordinary people with potential, flexible minds, and familiar with medicinal materials, searching for spiritual grass for him, in addition, the royal family of the Great Chu State, every year, in accordance with his requirements, throughout the country, handed over all kinds of spiritual grass, although the grade of spiritual grass is low, but the number is huge.

Shi Guoshi is not a fool, and even he is not shrewd by anyone. If you want to leave the Netherworld Hell, and if you want to unlock the prohibition on your body, there is only one way, and that is to improve your strength! As long as your strength improves, if he can reach the realm of Zhengang, then the prohibition on his body will naturally be solved.

Therefore, in the massive amount of spirit grass handed over by the royal family every year, Shi Guoshi would secretly deduct a large amount of spirit grass and accumulate it for himself, refine the pill, and improve his cultivation. Therefore, Shi Guoshi's collection of things is very much, if he wants to dedicate these massive spiritual grasses to Xu Feng, it means that he has been working hard to make wedding dresses for others for several years.

You must know that those pills and spirit herbs together can be described as priceless resources, and they are even enough for a third-rate sect to open up the supply and let the disciples of the sect cultivate for more than a year!

Moreover, what made Shi Guoshi jealous was that he was not Xu Feng's opponent at all, if after handing over his treasures, if Xu Feng turned his face and killed the killer mercilessly, he still had no choice.

To gamble, or not to gamble?

Shi Guoshi hesitated and couldn't decide.

"What's the matter, looking at your appearance, it seems that you are very dissatisfied?" Xu Feng looked at Shi Guoshi's uncertain face, a glint shot out of his eyes, and said coldly: "In that case, then I'll kill you, and then, I'll go to find your treasures, you have to think clearly, for me, it's just a waste of time, as long as I'm willing to spend some time looking for it, the treasures you have looted will definitely be found by me!"

Feeling the murderous intent emanating from Xu Feng's body, Shi Guoshi was helpless, so he could only nod and agree: "Okay, I promise you that I will dedicate all the treasures and resources I have treasured over the years to you, but I hope that you can use your natal divine seal to make a poisonous oath, after you get the treasure resources again, you will give me a way to live, you can't kill me, only in this way can I believe it, otherwise, I would rather be killed by you now, and then let you find it yourself, and I will not take the initiative to dedicate it to you!"

Oath to the natal gods?

Xu Feng raised his eyebrows and said, "Okay, since that's the case, then I'll promise you." ”

"I swear by my natal divine seal, after getting the treasure resources of Shi Guoshi, I will let Shi Guoshi leave, and in the future, I will never look for him to retaliate, if I violate the oath, let my natal divine seal break!"

Xu Feng soon made an oath.

On the Tian Yuan Continent, the oath issued by one's own natal god is the most serious and formal oath. If a person violates this oath and commits something treacherous, then the natal seal will really break.

There is no doubt about that.

The god seal has a spirit, and the natal god seal is even more magical.

As Xu Feng's words fell, suddenly, he felt that in the surrounding void, there seemed to be an invisible force that came through the void and entered his body.

Immediately, Xu Feng felt that this force seemed to be near the Divine Seal in the depths of the Sea of Knowledge, forming an existence similar to a prohibition, but it was definitely not a prohibition. He could feel that if he violated the oath he had just made, this power would explode and be countered by the oath.

"I see. No wonder this guy, let me swear by the Natal Divine Seal. "It was the first time for Xu Feng to swear with the Natal Divine Seal.

"Okay!" Shi Guoshi's expression relaxed, "The oath has been fulfilled, I believe you also feel the power of the oath now, if you want to kill me after you get the treasure resources, then even if I die, the power of the oath will make your divine seal broken, and your cultivation will drop to the realm of body refining, and in the days to come, even if you get a great adventure, it will be impossible to resume your cultivation!"

"Hmph, don't talk nonsense, where are all the treasure resources you looted?" Xu Feng looked at him coldly, and laughed secretly in his heart.

"In a barren mountain near the Great Chu Kingdom, I'll show the way, and you can fly me over!" Shi Guoshi hurriedly said.

Xu Feng raised his eyebrows, and secretly thought in his heart, this guy is really cunning, logically speaking, most people will hide such things not far from their neighborhood, preferably in a place where they can see it every day, so that they can rest assured. And this guy actually hid something in a barren mountain, if he hadn't taken the initiative to say it, he would definitely not have found it!

Shi Guoshi's meridians were all imprisoned and blocked by Xu Feng, and his cultivation could not be exerted at all, Xu Feng picked him up, and under his guidance, he flew hundreds of kilometers to the east, only to see seven or eight barren mountains of varying heights.

These are really a few barren mountains.

The mountain was barren and bare, and as far as the eye could see, there were stones everywhere, and there was hardly a tree, and there was not a single grass, except for a few eagles, hovering over the mountain. No one is interested in coming to such a place, and it is precisely because of this that Shi Guoshi has taken a fancy to this that he has hidden all the countless spiritual herbs and pills he has scavenged here.

"At the foot of the mountain on the left. ”

Shi Guoshi opened his mouth and said, Xu Feng followed his guidance, took him, flew over quickly, fell to the foot of the mountain, and threw Shi Guoshi to the ground casually, Xu Feng glanced around.

At the foot of the mountain, there are gravel and gravel of different sizes everywhere, and occasionally you can see the bones of several unknown animals, presumably the food captured by the eagles, and after eating, they are thrown here, and a smell of decay spreads in the air, making it look particularly barren and lonely.

Xu Feng raised his eyebrows, and his eyes looked at the place about a few hundred meters high from the foot of the mountain, which was empty, but he felt that the Heaven and Earth Yuan Qi there was slightly stronger than nearby. However, it is only at the foot of this mountain that you can feel that if you are a little farther away from here, unless you deliberately observe it, it is impossible to notice that there is a trace of unusualness there.

"Where is the thing?" Xu Feng turned his head and glanced at Shi Guoshi.

"Yes. Shi Guoshi sighed, and had some admiration for Xu Feng's keen attention.

Xu Feng didn't answer, he dragged Shi Guoshi, and in a flash, his body flashed, and he appeared in a place that was slightly different from the surroundings.

"Huh, it's a formation!"

After coming here, Xu Feng thought about it for a while and understood. Obviously, Shi Guoshi carved a formation pattern here, and arranged a formation that could cover people's eyes, covering this place.

After staying in the Qimen Ruins for a long time, Xu Feng also had some understanding of the formation. I know that there are some formations, which are not very powerful, but they can play the role of a mirage and obscuring people's eyes. For example, around a lake, the formation pattern is engraved to hook the vitality of heaven and earth, and the lake is hidden, and in the eyes of outsiders, the original lake has become a flat land.

If you want to break this kind of formation that covers people's eyes, you have to see how strong the person who inscribes the formation is, and how deep the understanding of the formation is. Luo Qi, the founder of Qimen, is a genius who comes out once in ten thousand years, and the inscribed array he arranges is infinitely powerful, and it can truly reach the point of covering the sky and the sun!

At the beginning, the people of the Rejuvenation Valley and the Blood Moon Sect entered the Qimen Ruins, and they didn't know how many powerhouses in the Divine Power Realm were trapped in the formation and couldn't get out. Just like Lin Ran, a powerhouse in the realm of supernatural powers, his cultivation reached the realm of illusionary gods, but after he activated the formation to open a defensive counterattack, he still died tragically in the formation.

"You set up this formation?"

Xu Feng did not rush to break the formation, but looked at Shi Guoshi with an inquiring eye.

"I'm not proficient in the formation pattern, this formation was arranged by my junior brother at the beginning. Shi Guoshi explained, and immediately, he honestly told Xu Feng where the entrance of this formation was and how to get in.

Xu Feng shook his head, "Don't be so troublesome, since it was arranged by your junior brother, then I will forcibly break this formation! Anyway, in the future, there will be no need for this place to exist!" As he spoke, he calmed down and carefully observed the changes and fluctuations of the surrounding heaven and earth vitality.

Without absolute certainty, Xu Feng would not enter the formation according to the method that Shi Guoshi said. Although, outside the formation, forcibly breaking the formation is much more difficult than forcibly breaking the formation after entering the formation, however, Xu Feng doesn't know what's strange in this formation, so for the sake of safety, he would rather spend some trouble and lose the true yuan power than go in to break the formation!

"Zhirou once said that the method of forcibly breaking the formation, the reason why the formation can have various effects is because the heaven and earth vitality acts on the formation! Heaven and earth vitality is the source of all things, the root of heaven and earth, it is extremely magical, and the formation can only exert the power of the formation after absorbing a large amount of heaven and earth vitality, so if you want to break the formation, as long as you prevent the formation from absorbing the heaven and earth vitality, you can achieve the purpose of breaking the formation!"

"There are many ways to prevent the formation from absorbing the Heaven and Earth Yuan Qi, for example, if there are two masters of the Divine Power Realm fighting, then the Heaven and Earth Yuan Qi will fluctuate violently and will be disturbed...... However, I can also use another method, which is to absorb, refine, and compete with the formation for the Heaven and Earth Yuan Qi here, so as to achieve the purpose of preventing the formation from absorbing the Heaven and Earth Yuan Qi!"

Xu Feng had an idea in his heart.

There are only a few barren mountains here, which are extremely barren, and in such an environment, the Heaven and Earth Yuan Qi is much thinner than other places.

With Xu Feng's terrifying cultivation method, once he cultivated, he would absorb all the Heaven and Earth Yuan Qi within a few miles of him into his body!
