Lin Feng withdrew his natal essence blood back into his body, and Mo Dongyu's mana was permanently sealed by him in the jade bottle, as long as the jade bottle was not broken and the medicinal liquid in the jade bottle was not lost, Mo Dongyu would never know that the mana he applied to Lin Feng's blood oath would be invalid from this moment on.

After the blood oath enters the body, it will have a strong impact on the monk's divine thoughts, so most disciples need to go through a period of adaptation after submitting the blood oath, which can be as short as a few days or as long as several months, which is an extremely small retreat to familiarize themselves with the changes that have occurred in their divine thoughts.

For Lin Feng, this time did not exist, he set up a strict defensive circle on the cave mansion, and after using the Extraction Technique to break the blood oath, he began to focus on his business.

The first thing to do is naturally to take out the void spirit bamboo full of Lanxi water!

Lan Xi Shui has incredible magical powers for the adsorption of spiritual power, if it weren't for the existence of the Void Spirit Bamboo, Lin Feng might not have thought of any other way to be able to smoothly take out such a large amount of Lan Xi Shui from the Netherworld.

It is almost impossible to transfer the Lanxi water, so even if a monk finds its traces, it can only be refined on the spot where it is generated, but in the process of refining, its consumption of spiritual power is extremely huge, and the environment in which it is located is mostly harsh.

Even if it is a Yuan Infant Stage cultivator, with his powerful mana, he barely succeeds in refining, the number is extremely rare, and it is inevitable that he will miss in a hurry, and it is difficult for the quality and attributes of the refined Lanxi Water to reach a higher realm.

Lin Feng used the Ancient Divine Wood Void Spirit Bamboo to easily take out the Lanxi Wastewater, in the Void Spirit Environment, the Lanxi Void Water could be well preserved, but Lin Feng did not dare to store it directly in the Sumeru Illusion Ring, because the Lanxi Void Water would adsorb the spiritual power of all nearby attributes without refining, and the large number of elixirs in the Sumeru Illusion Ring would also cause devastating damage as a result.

At this time, the Lanxi water was taken out by Lin Feng from the Void Spirit Bamboo drop by drop, and each drop was purified by excellence, and then refined in detail, so that its purity and attributes reached a realm of almost perfection!

Lan Xi water is the core material for casting the Wuji Water Yuan Sword, in order to find it, Lin Feng used to sell all kinds of sky-high elixirs at the boutique trade fair in Jindu City, but in the end he found nothing, he didn't expect that there would be such a rich harvest in the Silky Domain.

In addition to the Xuyuan Sword, the Shui Yuan Sword is the Zuihou sword of the Wuji Nine Yuan Sword, as long as these eight swords are gathered, the Wuji Sword Shadow can exert the highest power, and once the Xuyuan Sword is cast, it can give rise to the high-strength sword momentum of the Nine Yuan Sword Technique: Daze jianzhen!

It is worth mentioning that the Wuji Nine-Yuan Sword is a magic weapon of the original element, and the outline of the Nine-Yuan Sword Technique requires that each sword must be of the best grade, and urging it requires extraordinary mana strength and divine consciousness strength, and the power it can exert is completely different from other magic weapons, but it is progressive at any time!

In the later stage of the Nine Yuan Sword Technique, the power contained in each move is closely related to the monk's own cultivation realm, and the watershed of this stage is the third beginning of the Infinite Sword Shadow!

The Five Elements and Eight Yuan Swords are all together, and with the strength of the late stage of the Jiedan, they can urge the third sword momentum of the Wuji Sword Shadow, but with the improvement of strength, the third weight of the Wuji Sword Shadow spawned by the realm of the Yuan Infant Stage is far more powerful than the power generated in the late stage of the Yudan!

The power of the Primordial Magic Weapon will continue to improve with the nourishment of the monk, and the mana stimulated will naturally be even greater, so the Nine Yuan Sword Technique starts from the third level of the Infinite Sword Shadow, and the power is no longer static, but closely related to Lin Feng's cultivation.

In addition to the Lanxi water, Lin Feng had already gathered all the materials needed for the Wuji Water Yuan Sword, and now that everything was ready, and there was a temporarily stable environment, the refining of the Water Yuan Sword was naturally put on the agenda.

More than ten days later, in Lin Feng's cave mansion, the eight-handled Yuan Sword was suspended in front of him, and he was sitting in a precarious position, urging the magic technique to make the Five Elements Eight Yuan Sword rotate, forming a jianzhen form around the top of his head.

This so-called jianzhen, known as the Infinite Sword Domain in the Infinite Sword Shadow, is also a sword momentum that Lin Feng can exert the strongest power of the Infinite Sword Shadow at this stage!

At this moment when the Shui Yuan Sword was cast, Lin Feng truly realized the powerful power contained in the Infinite Sword Shadow, but in the current Cave Mansion, he couldn't test it at all, but the joy that the Five Elements and Eight Yuan Sword brought to him was extremely exciting!

Whether it is a natal magic weapon or a natal magic weapon, it must be cultivated in the Yuan Shen for a long time, and with the continuous improvement of the monk's cultivation, the Yuan magic weapon and the natal magic weapon must also be continuously upgraded, and each level up, a specific high-level material needs to be added to strengthen the power and strength of the magic weapon.

Lin Feng's natal magic weapon contains nine swords, if he refines the natal magic weapon blood dragon silk in the future, then the future upgrade will be extremely financially expensive, ordinary monks, to improve a natal magic weapon with all their might, it is enough to make financial resources more and more scarce, because the high-grade materials that improve the level of the magic weapon are the most difficult to find and have no price.

Lin Feng didn't take financial resources to heart from beginning to end, for him, the improvement of strength always comes first, but unfortunately, with his current strength, it is not enough to refine the Void Spirit Bamboo, let alone refine the Dragon Tendon, so the Void Yuan Sword and the Blood Dragon Silk can only be planned after the baby is married, and even if it is refined into the Void Yuan Sword, without the mana of the Yuan Infant Realm, it will not be able to urge Daze Jianzhen at all.

Lin Feng's yearning for Daze Jianzhen and Blood Dragon Silk had long been admired in his mind, and these two killing techniques and killing weapons, in the Nine Yuan Sword Technique and the Quenching Dragon Technique, had a clear hint, and the power they erupted would definitely be extraordinary!

The eight Yuan Swords were withdrawn from his body, and Lin Feng then swallowed several cowardly miscellaneous elixirs, trying to get rid of the miscellaneous yuan cowardice that had accumulated in the Yuan Shen for a long time, cowardice is a very long and difficult process, it requires an extremely long retreat to complete, and even some stubborn miscellaneous elements, if there is no super strong elixir, they will never be able to get rid of cowardice from the body.

Lin Feng knew that he couldn't achieve it overnight in the short term, and there was not enough environment to enter the retreat, but in the Realm of Silk, he had already accumulated too many miscellaneous elements in the Yuan Shen, which not only had a great impact on the power of mana, but also at this stage, he could no longer continue to devour, so he took this opportunity to get rid of those miscellaneous elements that were easier to get rid of first, so as to reduce the burden of the Yuan Shen.

Three months later, Lin Feng opened his eyes, and the miscellaneous elements in his body had been eliminated seven or eight out of ten! In such a short period of time, to eliminate a huge number of miscellaneous elements, the only condition he relied on was a large number of incomparably precious miscellaneous elixirs!

What Lin Feng uses is the large-ripe state of the meal grass, and the medium-ripe ice banana fruit, which is close to the realm of the large-ripe realm!

The large-ripened meal grass is suitable for the cowardice of the Dan period, and its effect is medium, but Lin Feng completed the Dan and took it with the Hua Dan that was refined into Dan, and the effect of cowardice and miscellaneous was doubled several times!

As for the Ice Banana Fruit, it is suitable for most of the difficult and miscellaneous elements, and the effect is even better, but in the state of large ripeness, the medicinal power is extremely fierce, and it is the mana of the Yuan Infant Stage Monk that can control it, Lin Feng naturally does not dare to trespass, so he can only limit it to below the great ripeness.

The Meal Pill and the Ice Banana Fruit basically removed seven or eight out of ten of the miscellaneous elements in Lin Feng's body, and the remaining less than thirty percent were all with special attributes, which were too closely combined with Lin Feng's origin spiritual power, and it was extremely difficult to get rid of it, without a stronger elixir, and for a long time, it was impossible to eliminate it at all.

Therefore, Lin Feng had to give up for the time being, and once he had a stable environment, he immediately entered the Great Retreat and made every effort to clear these miscellaneous elements.

Next, Lin Feng sorted out a large number of items in his hand, re-refined a batch of commonly used materials, and then carefully flipped through the many ancient books obtained from Jin Zhen Ancestor, one by one.

After another month passed, Lin Feng went through all the contents of the jade slips, these ancient books collected by the Jin Zhen clan involved a wide range of fields, whether it was exercises, secret arts, rumors, anecdotes, materials, strange arts, and even divination, etc., almost everything.

And the one that Lin Feng paid the most attention to was an ancient text called "Annihilation Mantra".
