This kind of practice of using the Yuan Shen of the Foundation Building Period to shape auxiliary exercises is probably only possible for Lin Feng in the entire cultivation realm. Not only is it fast, but it is also more accurate, and it may not have taken him decades, or even hundreds of years, to shape the auxiliary exercises, but it only took him a few days!

When the auxiliary technique of the Nine Yuan Sword Technique was finally successfully shaped, the Yuan Shen of the Lewd Leopard had already consumed nearly half of the spiritual power essence, and at this time, Lin Feng also opened his eyes that he hadn't opened for a long time.

Sending the jade slip of the Nine Yuan Sword Technique into the Sumeru Illusion Ring, Lin Feng took out a low-grade flying sword from the storage bag, its style did not match the Nine Yuan Sword Technique, but in Lin Feng's storage bag, there was no more consistent sword-shaped attack weapon.

Lin Feng walked out of the cave and came to a remote foot of the mountain, urging the flying sword according to the technique of the Nine Yuan Sword Technique, but the flying sword did not move at all. It seems that if you want to use the Nine Yuan Sword Technique, you can only do it after the Qi training period.

However, Lin Feng didn't give up just yet, the devouring technique of the immortal net was activated again, and Lin Feng's primordial spirit was full of the pure spiritual power of a foundation building period monk, only to see him push it sideways, and the flying sword flew out with a whoosh!

There was an earth-shattering bang! The first form of the Nine Yuan Sword Technique, "Breaking the Yuan Slash", broke out successfully! Lin Feng was already standing on the spot!

Although he had already anticipated the extraordinary power of the Nine Yuan Sword Technique, when he saw it with his own eyes, he was still deeply amazed! On a small hill opposite, a large hole several zhang in size was pierced by the flying sword just now, and the top of the mountain looked crumbling!

The Yuan Breaking Slash performed at the Qi cultivation stage can all have such power, and the future achievements of the Nine Yuan Sword Technique will definitely be even more terrifying!

Next, Lin Feng tried to use the devouring miracle effect of the immortal net to perform the second form of the Nine Yuan Sword Technique, but the result was unsuccessful. [ ] The reason is actually very simple, because the second form of the Nine Yuan Sword Technique can only be used until the foundation building stage.

Although Lin Feng's immortal net had the primordial spirit of the foundation-building period monk, it was not the same as his own primordial spirit, and the transformed spiritual power could not reach the true strength of the foundation-building period monk, so the second-style sword technique could not be used.

Theoretically, if there is a Yuan Shen of a cultivator in the Yu Dan period, or a demon beast inner Dan above level 6, the second form of the Nine Yuan Sword Technique should also be able to be cast.

In fact, it was impossible, because even if there was such an inner pill, Lin Feng would not dare to devour it, his meridians would definitely not be able to withstand such a powerful spiritual impact, and once the meridians were broken, his life would be completely scrapped.

In fact, the spiritual power essence devoured through the immortal net was directly used to cast the Nine Yuan Sword Technique without refining, and its power was still greatly reduced. If Lin Feng reached the realm of the foundation building stage and used his own origin spiritual power to stimulate this type of Yuan Breaking Slash, the power would be even greater!

However, no matter what, Lin Feng was still very excited to be able to use the first form of the Nine Yuan Sword Technique at the stage of the rotation period. Although after using it, the spiritual power in his primordial spirit fell into a short-term empty state, and if he wanted to use mana at this time, he could only wait for the immortal net to inject the devoured spiritual power into the primordial god again.

Having learned the Nine Yuan Sword Technique's Breaking Yuan Slash undoubtedly made Lin Feng's combat ability a step further, especially in a evenly matched confrontation, this sword move was likely to have a miraculous effect of killing with one hit.

However, after it is activated, it will fall into a short emptiness, and it may also put itself in danger while severely damaging the enemy, so this move should not be used lightly until it is absolutely necessary.

Lin Feng was very interested in retracting the flying sword and was about to return to the cave mansion, but suddenly remembered that today seemed to be the day when the Dan Ceremony began, so he hurriedly set up the flying magic weapon and galloped away in a certain direction of the Qingdan Gate.

The direction that Lin Feng was heading to was the Dan Peak of the Qingdan Gate. This is a towering mountain, the aura of the top of the mountain is extremely rich, and the Dan Square of Qingdanmen is located on the top of this mountain.

When Lin Feng arrived, there were already a lot of people on Dan Peak, and it was impossible to use the flying magic weapon here, so Lin Feng had already put it away and climbed up step by step from the bottom.

In the bustling crowd, Lin Feng was actually very excited. Because he grew up in the Lin family in the Taiyi Mountain Range, he rarely had the opportunity to see such a lively scene except for hard cultivation, so he finally opened his eyes to all kinds of items.

Starting from the bottom of Nondanfeng Peak and continuing to the top of the mountain thousands of feet high, there are stalls of various sizes along the way. The monks who set up the stalls are also of all shapes and sizes, most of them are below the foundation building period, and some of them do not even belong to the Nanyue cultivation realm, but come from unknown foreign regions.

The Qingdanmen Lundan Ceremony, which takes place once every 60 years, is indeed an unprecedented grand trading event. The seven major factions in the Nanyue Xiuzhen Realm, the powerful Xiuzhen family, and the well-known scattered cultivators who traveled all over the world all set up their own special booths in conspicuous positions, and of course, they all needed to pay a certain amount of money to the Qingdanmen.

As for other ordinary families or casual cultivators, as long as they pay a very small amount of spirit stones, they will also have a place to set up a stall, where they can sell the materials in their hands at will, and the price is also determined by themselves, and the transaction process is absolutely fair.

Along the way, Lin Feng was dazzled by the dazzling array of cultivation materials, most of which he didn't know at all, let alone the price and use. At the same time, there were constantly all kinds of shouts from the bustling crowd, some bargaining, some boasting, and some monks who were similar to Lin Feng, seeing some kind of unknown material, curious and constantly asking.

Lin Feng looked at it as he walked, those strange materials made him dizzy, in fact, he knew that most of these materials he couldn't use at the moment, but with the improvement of his cultivation and realm, more and more materials would be used in the future.

It stands to reason that when his cultivation improves, he can buy relevant materials according to his own needs, but I am afraid that he will not encounter such a grand trade fair, and some rare or cold materials are often only seen at large-scale trade fairs.

Therefore, after Lin Feng's novelty passed, he began to think about buying some items that might be used in the future, especially those materials that were not often seen in ordinary markets or trade fairs. But the problem is that he doesn't know what materials will be used in the future, let alone which materials are not easy to see in ordinary markets.

Therefore, Lin Feng's attention began to focus on the stalls that specialized in selling jade slips, and those stalls were all placed with jade slips of different styles, and there was an eye-catching note on the surface of the jade slips, which was written with a brief introduction to the contents of the jade slips, which was for others to identify and choose.

However, Lin Feng searched for a long time, but he didn't find the kind he wanted. All he saw were introductions to some ordinary materials, or some auxiliary exercises that were not in the flow, and even some unknown major exercises, but the goods didn't seem to be very good.
