Su Yaowen was working overtime to enter the contents of the book, but Bai Xingkong went to the treasure house and took the things away first. There were not many treasures in it, if not very few, a rough silver bracelet and a turquoise jade bottle, just these two things.

Seeing that there were only two things in the treasure vault, Bai Xingkong was not too surprised, Ouyang Blood's phantom had already been explained. That silver bracelet is a high-grade storage magic weapon, the magic weapon has its own space, which can store a large number of items, and the only remaining precious items of the Ouyang clan are stored in the bracelet.

And the bottle next to it is also not simple, it contains a large amount of spiritual water, it is the best spiritual water left hundreds of thousands of years ago, and its value is not lower than the contents of the silver bracelet. The level of spiritual water is very high, and the spiritual energy contained in each trace of spiritual water is no less than the entire superb spiritual stone. It's a pity that after so many years, the people of the Ouyang clan have also used a lot, and the only remaining spiritual water in the bottle is not much, barely enough for Bai Xingkong to use it until the merger period.

Su Yaowen and Bai Xingkong both got a good harvest underground, but the people of the major forces outside were extremely distressed, and they didn't have much income so far. The defensive formation outside the giant palace is very complicated, it is estimated that it was arranged by the Mahayana monks, not only the defensive strength is high, but it can also ensure that it is in operation for a long time, and everyone is also a little headache.

Although the scene gathered the formation masters who were in the top ranks of the current cultivation realm, their cultivation and knowledge limited their formation level. Even if these formation masters join forces day and night to attack, it will take two or three months to open a gap, and they can't rest and stop during this period, which is a great test of everyone's mental strength and endurance.

Knowing that this is hard work, these formation masters can't back down because of this, everyone believes it. There must be a large number of treasures buried in the giant palace to use such a powerful defensive formation to protect it, even if the formation masters of the major forces have the heart to give up, others will not agree.

Time has passed in this way, and more than ten days have passed in everyone's busyness, and Su Yaowen has not had a good rest in the past few days, although the work of entering the content of the book has bamboo puppets and scanning magic weapons to do it for him. But he can't take it lightly, Bai Xingkong is still underground, who knows when he will go to the library pavilion.

Bai Xingkong had spent more than ten days in the retreat room, and Ouyang Xue had left behind a technique that was specifically suitable for the cultivators of the Blood Spirit Root, and he still needed to spend some time studying and studying it. And the reason why he was able to cultivate this exercise was because he also contained a blood spirit root in his body.

Ouyang Blood had already mentioned before that the Blood Spirit Root was a hidden Spirit Root, which was different from the Five Elements Spirit Root. It cannot be verified by general methods. People who have blood spirit roots will also have explicit five element spirit roots, and Bai Xingkong is recognized as having dual spirit roots precisely because he showed two attributes of gold and water when he was doing the spirit root test.

In fact, Bai Xingkong had doubts about this a long time ago, logically speaking, he was just a monk with a double spirit root, but his cultivation improvement speed was not slow at all, much stronger than Qu Ruyan and Han Bing'er who had a spirit root. Although he has been all these years. There have been a lot of good adventures, but the speed of this ascension is still too terrifying. It's just that he couldn't find a specific reason.

Bai Xingkong also found that especially when fighting, as the intensity of the battle increased, the more serious the opponent's injuries became, and his cultivation always had the illusion of steady improvement. He didn't know it before, but after the description of the information left by Ouyang Xue. I finally understood what was going on. The owner of the blood spirit root, the body will unconsciously absorb the aura in the blood and replenish it into his body, so as to improve his cultivation. And the battle is when blood is most likely to flow.

Although the Blood Spirit Root is one of the mutated Spirit Roots, it is more like a latent disease, and it needs to trigger some kind of condition before it can be discovered by itself. A person with this spiritual root, if he has not sucked the blood of others, will not have any abnormalities in his body. Once the blood is ingested, it is as if some kind of shackle has been opened and it becomes Ouyang blood, and in a short period of time, the cultivation will inevitably rise sharply, but it will also be accompanied by huge sequelae.

The most common is that every month on the night of the new moon, the night when the yin attribute energy is greatly raging, it will have a huge impact on its body. First, the aura in the body is suppressed and difficult to control, and then it will gradually lose control of the aura until the night of the new moon passes. At this time, it will lose any strength to resist, like a lamb to the slaughter, at the mercy of the mermaid.

Bai Xingkong studied the information left by Ouyang Xue, and according to the method introduced there, he did a test experiment on the blood spirit root, and the results were self-evident. With the discovery of his own blood spirit root, Bai Xingkong also sensed that there was a special blood-colored aura lurking in his body. These blood-colored auras faintly reveal a yin and evil aura, which is obviously different from the righteousness and vigor of the aura of heaven and earth, and these auras are all aura that Bai Xingkong has unintentionally absorbed during the battle for many years.

Fortunately, these special blood-colored auras were only absorbed from the skin, not directly sucking blood from the mouth, so they would not have any bad effects on him. However, there is a powerful aura in the body, but it cannot be used freely, and it is not what vain Xingkong hopes.

Although Bai Xingkong did not suck blood, so as to speed up his cultivation, but some of the exercises left by Ouyang Blood were also about the control method of this special aura, as long as he practiced a little, he would be able to use it skillfully, and it would be good to master one more life-saving technique.

This special aura, called blood attribute aura by the people of the Ouyang clan, is the unique aura attribute of the blood spirit root monk, compared with the general five elements aura, both strength and quality, are much exceeded, when used in battle, can strengthen their strength, but unfortunately this aura is not very convenient to supplement.

If you want to increase the blood attribute aura in your body, either during the battle, your body will automatically absorb the blood spilled from the opponent's wound, which is safer and not addictive, and it will not have any side effects on your body later. The other more evil way is to suck blood directly from the mouth to achieve the best effect, but it is very addictive, and you need to suck fresh blood every once in a while, otherwise there will be the painful torture of aura backlash.

Knowing that sucking blood would bring all kinds of negative effects, Ouyang Blood still embarked on this path back then, and the biggest reason was because of his qualifications. Excluding the hidden blood spirit root, Ouyang Blood's dominant spirit root is a four-attribute miscellaneous spirit root, and his talent is not outstanding, and it can even be said to be very poor, relying on normal cultivation alone, his future achievements will definitely not be very high.

It was precisely because of this that Ouyang Blood was attracted by the many benefits of sucking blood, and fell into the Demon Dao, making himself break through to the Great Perfection Realm of the Merge Period in just over a thousand years, and become the strongest person in the cultivation realm at that time.

Bai Xingkong didn't plan to follow the old path of Ouyang Blood, but he was very interested in the higher-level aura of the blood attribute aura. If he could use those latent aura, Bai Xingkong was very confident that he would defeat the monks in the early stage of Yuanying with his cultivation in the late stage of the Dan Dynasty and create a new record in the cultivation realm.
