"The highest level of formation can be arranged?"

As soon as he heard this, Lin Feng was also stunned.

What's going on?

Because when he left the earth, Xu Minjing was just an ordinary person, and he didn't even have the ability to cultivate, and besides, there weren't so many resources on the earth for her to cultivate, so how could she suddenly become an eighth-level formation master?

"Yes, Dad, don't you know? Although Mom's physique is not good, and her cultivation is only in the Jindan stage, her attainments in the formation are unmatched. The outermost sixth-level formation of Tianmu Peak is actually only the simplest, and the formation inside is even more terrifying. ”

Lin Bian said proudly, "Moreover, recently, my mother is still studying some ancient killing arrays, but it's a pity that there are not enough spirit stones to drive and test ......."

When he said this, Lin Bian also muttered and sighed: "The cultivation environment of our earth is really too poor, and there is not much spiritual energy in the air! There are basically no spirit stone mines, and spirit stones are too scarce......

"Spirit stones?"

As soon as he heard this, Lin Feng's heart was happy, fortunately, his father was prepared! When he first swept up, he got so many spirit stones and put them in his divine water space. There is also the one of the Pit Cangyun Sect, which has also accumulated a large number of spirit stones, just so that one day he can return to the earth and use these spirit stones.

Sure enough, even if ten years have passed now, the cultivation environment on the entire earth has not changed because of this. The scarcity of spirit stones has become a natural obstacle that restricts the cultivation of cultivators on the entire earth.

Perhaps, the physique of earthlings is very suitable for cultivation, and the difficulty of cultivation is one-tenth or even one percent of that of cultivators on other planets.

However, the aura on the earth is extremely scarce, and it is difficult for a clever woman to cook without rice, and the cultivation of the people on the earth, no matter how good the talent is, without the aura, must be absorbed from the breath little by little, and the speed is much slower.

And in this case, as long as there is a sufficient supply of spiritual energy, it is completely a matter of accumulation, and it will break through several layers of cultivation at once.

"Yes, Dad, don't look at me and my second brother's cultivation has reached the early stage of the Yuan Infant, that's because our physique is special, and we can quickly absorb spiritual energy to advance. Therefore, my mother and uncles saved the spirit stones for us, and with some spirit stones in the storage bags we snatched from those extraterrestrial demons, we could barely reach the Yuan Infant Stage ......."

Lin Sifeng also said with some hatred, "And damn the Outer Heaven Demon, since we knew that we lacked spirit stones, when all the disciples came out, there weren't many spirit stones in the storage bags......!

"It's just a spirit stone! children, don't worry! Dad doesn't have anything else, spirit stone...... Let's go back to the base first, and then think about it in ......the long run."

After learning about this situation, Lin Feng's heart was also happy, and now the cultivator door of the Great Sage Group on the earth is estimated to be ready, only the spirit stone is missing.

In this way, what is there to be afraid of?

Lin Feng looked at the piles of high-grade spirit stones in his divine water space, and there were countless middle-grade and low-grade spirit stones, even he couldn't count them.

After all, this is the accumulation of tens of thousands of years of accumulation between the two sects!

In that cultivation realm, there is a lack of exercises, magic weapons and formations, but there is no shortage of spirit stones, this is that things are scarce and expensive, there are many spirit stones, but they are not rare, and any disciple in that world will carry hundreds of thousands of lower-grade spirit stones when he goes out.

And hundreds of thousands of low-grade spirit stones, I'm afraid I can't even buy the most ordinary magic weapon.

Now, not to mention anything else, Lin Feng alone has almost tens of millions of high-grade spirit stones.

You must know that the exchange ratio between spirit stones is 100 to 1, that is to say, 10 million high-grade spirit stones are 1 billion medium-grade spirit stones, and 100 billion low-grade spirit stones.

A normal cultivator, promoted from the Qi cultivation period to the foundation building stage, only needs a thousand lower-grade spirit stones, and when promoted to the Jindan stage, it is only 10,000 lower-grade spirit stones, and when promoted to the Yuan Infant stage, it is only 100,000 lower-grade spirit stones.

In this way, the top-grade spirit stones that Lin Feng possessed alone were enough to cultivate one million Yuan Infant Stage cultivators.

The spirit stone is enough!

Immediately afterwards, the three fathers and sons flew to the top of Tianmu Peak, and the eldest son Lin Sifeng fell directly and came to the front of an old locust tree, and then turned left three times around this old locust tree, and then turned five times, and shouted: "Open!"

Then, Lin Feng was surprised to see that the rock behind the old locust tree actually cracked in the middle, and a secret passage appeared.

"Dad, let's get in! This passage is a one-time one, and every time we enter and exit the base, a unique return passage is generated through a specific algorithm. This is Min Jing's mother's special change to this formation, which avoids the possibility of being taken advantage of by the enemy to the greatest extent. ”

Lin Sifeng was the first to walk into the secret passage, followed by Lin Feng and Lin Bian.

Seeing the use of this formation, even if Lin Feng himself was a formation master, he couldn't help but feel ashamed. It can be seen that Xu Minjing's use of the formation has reached a level of supernatural ability.

Moreover, the secret passage inside is not so simple, all the way over, Lin Feng has seen no less than ten formations above level five inside.

These formations all have a common feature, that is, they don't need to consume any spirit stones and spiritual energy, and all rely on a kind of ferromagnetic energy released by the Xuaniron ore in the entire Tianmu Peak.

However, if you think about it carefully, it is not difficult to find that this is also because there are not many spirit stones on the entire earth, and if you spend a lot of spirit stones to run the formation, it will be too wasteful.

It is no wonder that Xu Minjing would find another way, but instead use the ferromagnetic energy of this kind of dark iron ore itself.

When the secret passage was halfway through, suddenly the aura in the entire formation suddenly changed, and a voice that Lin Feng was too familiar with to be familiar with couldn't be more familiar, and asked Lin Sifeng who was walking in front very sternly: "Sifeng, haven't I told you and Chang'er countless times? Without our permission, it is absolutely not allowed to bring outsiders to our secret base in Tianmu Peak? You are still young, and the hearts of people outside are too complicated, what if the people who come in are traitors who have taken refuge in the Corpse Yin Sect?"

"Minjing's mother, we are not bringing outsiders......"

"Mom, look at it...... Who's coming......"

……

Lin Sifeng and Lin Chang didn't have the usual sense of guilt for being scolded, but they both shouted excitedly.
