Chapter 402: Family Spiritual Veins and Family Protection Formation are both upgraded

Time passed quickly, and in a blink of an eye it was almost time for the Xu family to hold the family opening ceremony.

For more than half a year, Xu Feng has been working non-stop. Apart from sending invitations everywhere, he is also preparing for the ceremony.

There was no way, there were only a few people in the family, and the three Taoist monks had to take care of the Tongxin Pavilion business and the children, so he had to do many things by himself.

After sending the invitation, he went to the Jiugong Sect to find his two masters and told them about upgrading the family's spiritual veins.

He is now in the late stage of Foundation Establishment, and his second-level low-grade spiritual energy is not enough. Not to mention that Luo Xinran and the others are also in Foundation Establishment, and the spiritual energy flowing out is not enough.

In fact, he should have done this long after he returned from Song Dynasty, but at that time he had not yet found out the spies hiding in the sect, so in order not to alert the enemy, he delayed it until this time.

When he was in Taimang Mountain before, he actually used the spirit gathering array to practice. Not only did it consume spiritual stones, but the effect was very average.

Upgrading the second-level spiritual veins is not a simple matter. There are many things involved. Finally, under the advice of the two real people, he went to find Luo Bin, the deputy master of the third-level formation mage.

After learning about his intention to upgrade his family's spiritual veins, Luo Bin gave him a long list of spiritual objects, all of which were needed to upgrade his spiritual veins.

The spiritual object listed in the first item is naturally the spiritual stone.

To upgrade a second-level low-grade spiritual vein to a middle-grade one requires fifty thousand low-grade spiritual stones, and to upgrade a second-order middle-grade spiritual vein to a high-grade one requires one hundred thousand low-grade spiritual stones.

Since Xu Feng wanted to directly upgrade the second-level low-grade spiritual veins to high-grade ones, the total number of spiritual stones was 150,000.

In addition, upgrading spiritual veins also requires the use of other spiritual objects.

To upgrade from the second-level low-grade to the second-order high-grade, dozens of precious second-order spiritual objects are required, and their value is not less than 100,000 spiritual stones.

Adding these together, the total cost of upgrading the spiritual veins should be no less than 250,000 spiritual stones.

When he heard this number, Xu Feng was not too surprised. He was mentally prepared for it.

Other families have accumulated spiritual stones for decades before they can raise their spiritual veins to a small level. Why? It's because the cost is too high.

Since he wanted to upgrade his family's spiritual veins in a short period of time, it was only natural that he would pay a huge price.

But there is a problem involved, a very serious problem, that is, he has no spirit stones in his hand.

Originally, he was awarded 500,000 low-grade spiritual stones for finishing third in the Alchemy Conference. However, he did not keep these spiritual stones, and they were all 'borrowed' by Gao Ruoyun, the senior Yuan Ying.

So now he can't hold so many spiritual stones in his hands.

After much thought, he had no choice but to go to the sect's contribution hall, hoping to exchange his contribution points for some spiritual stones.

He has accumulated a lot of contribution points over the years. His salary of 500 contribution points a year, after more than ten years, in addition to the part that he usually uses, there is still a huge amount of 5,000.

In addition to the 10,000-point reward he received for contributing the 'Tiangang Puppet Talisman' before, he now has a total of 15,000 contribution points.

If these contribution points are exchanged at a ratio of one to twenty, he can get three hundred thousand spiritual stones, which is equivalent to solving the problem of lack of spiritual stones.

But for such a major matter, the leader of the Contribution Hall would definitely not dare to make the decision on his own. He reported it to the top of the sect, and Master Lu naturally knew about it.

After calling him to criticize him and telling him not to waste his contribution points, Master Lu spent 250,000 spiritual stones himself to upgrade the spiritual veins on Taimang Mountain.

The reason why he did this is also obvious. After all, Xu Feng saved his life, and doing this can be regarded as repaying his life-saving grace.

After getting the spiritual stones, he came to Fangshi and spent half a month collecting all the spiritual objects he needed before preparing to take several real people back to Taimang Mountain.

Unexpectedly, Su Zhenren's words directly caused him to bleed again.

"Feng'er, since the family's spiritual veins have been upgraded, shouldn't the clan-protecting formation also be upgraded? The defense of the second-level mid-level clan-protecting formation is too weak. It only takes a few early-stage foundation-building monks to work together to break it. ”

Upon hearing this, Xu Feng was stunned for a moment, then clapped his head in annoyance and said:

"Oh, I was so busy upgrading the spiritual veins that I completely forgot about upgrading the clan protection formation."

Needless to say, the importance of the family protection formation is the most important guarantee for the safety of the family monks. Not only must it exist, but it must also be good.

Thinking of this, he turned his head to the full-time formation master, Deputy Head Luo, hoping that he could give some advice.

"Junior Brother Xu, for the sake of safety, I suggest you set up a third-level low-grade protective formation on the family mountain, so that the safety of the family can be guaranteed."

"Third-level formation? Even after Taimang Mountain's spiritual veins are upgraded, they are only second-level high-grade. How can a third-level formation be deployed?"

Xu Feng was greatly puzzled. Everything in the world of immortality has strict correspondence. Which level of spiritual veins corresponds to which level of formation. It is very rare to surpass the level.

"Who said that the second-level high-grade spiritual veins cannot be used to deploy third-level formations? It's just that after deploying the third-level formations, if you want to run them, you will definitely not be able to rely on the spiritual veins alone, and you will also need to consume a large amount of spiritual stones."

After listening to Deputy Head Luo's introduction, he fell into deep thought.

From the perspective of the safety of the clan members, the higher the formation level, the better. However, this also involves an important issue, which is the consumption of spiritual stones to maintain the formation's operation.

If it costs 30,000 to 50,000 a year, he can support it with the speed at which he earns spirit stones, but if it costs more than 100,000 a year, then he has to think about it carefully.

"May I ask the head brother, after the third-level formation is set up, how many spirit stones are needed to maintain it for a year?"

"Not much, just 50,000."

Hearing this, Xu Feng wanted to slap him in the face. Is this human talk? 50,000 a year, how much will it cost in ten years?

"What if the family protection formation set up is a second-level top-grade formation, how much will it cost?"

"The spiritual energy required for the operation of the second-level top-grade formation can be borne by the second-level top-grade spirit veins, without the need to consume additional spirit stones."

One is free, and the other requires a large amount of spirit stones.

For these two options, there seems to be no hesitation. Normal people will choose the free one.

But after thinking it over again and again, Xu Feng still chose 50,000 spirit stones a year to keep his family safe.

The second-level superior formation and the third-level inferior formation are two completely different concepts. The defense power is very different. The former can only block cultivators below the Jindan level, while the latter can block cultivators in the early Jindan stage. The safety performance is improved by more than dozens of times.

Under the protection of the two masters, Luo Bin personally went to the depths of the spiritual vein and invested all the spiritual stones and spiritual objects needed to upgrade the spiritual vein.

Relying on the huge spiritual energy in more than 100,000 spiritual stones, it took only ten days for the spiritual vein grade on the Taimang Mountain of the Xu family to easily achieve two consecutive jumps and become the second-level superior.

At the same time, when the spiritual vein grade broke through, it also fed back a lot of pure spiritual energy. Xu Feng's three Taoist companions and a pair of children all benefited a lot and broke through a small realm one after another, which was an unexpected surprise.
