However, after Zhou Yang participated in the exchange meeting, he immediately returned to the cave he rented to check the harvest of the exchange meeting behind closed doors.

In this underground exchange meeting, he gained a lot.

Not to mention anything else, just that one Tsukidan completely earned back ten times or dozens of times the five hundred spirit stones paid for participating in the exchange meeting.

At this time, after he returned to the cave, he also took out the medicine bottle containing the Tsukidan for the first time, poured out the pill and checked it.

He once took the Tsukidan Tsukidan, and later obtained a Tsukidan from Cao Wenjin, so there is naturally no problem with the identification of the Tsukidan.

After careful inspection, Zhou Yang was sure that there was nothing wrong with this pill, and then his eyes flashed, and a pale golden flame suddenly appeared in his palm, and the pill bottle that was originally filled with the pill was directly burned into a puddle of jade liquid, and he replaced it with another pill bottle on his body to fill the Zhuji Dan, including the pill bottle containing five third-order mid-grade spirit pills "Peiyuan Dan", and he also disposed of it in this way.

This is done, of course, just in case.

He offended the Purple Mansion Alchemist at the underground exchange meeting, although the other party was warned by Tian Wenxuan at that time and did not have a seizure, but who knows if the other party will do anything on the elixir given to him?

Whether it was the classics of the Immortal Cultivation Realm that he had read himself, or the teachings and admonitions of his elders since he was a child, he had said that when he went out, he should not easily drink and eat the spiritual wine, tea, and food given by anyone.

Because there are many strange spells and methods in the world of cultivating immortals, it is possible to track down the people who have eaten and used these things through these seemingly inconspicuous things.

Zhuji Dan and Peiyuan Dan are both refined pills, and generally speaking, it is very difficult to do anything in this kind of pill that has already been refined.

Because the elixir is made from the fusion and refinement of various elixir essences, it pays great attention to balance and stability, and when foreign substances penetrate into it, it is easy to destroy and disrupt the balance point in it, causing the elixir to fail.

Therefore, if the Purple Mansion monk really wants to do anything, it is most likely to do his hands and feet on the Dan bottle.

After dealing with the elixir, Zhou Yang took out the four Yin Soul Stones to check them.

These four Yin Soul Stones, the three egg-sized ones in front of them belong to the lower grade, and they can only be used to refine the third-order lower grade and the third-order middle-grade puppet beasts.

And that fist-sized Yin Soul Stone was enough to refine a third-order high-grade puppet beast.

However, the puppet jade slip that Zhou Yang obtained only recorded the refining methods of two third-order lower-grade puppet beasts, and the current materials on his body were not complete, so he couldn't try to refine third-order puppet beasts for the time being.

Therefore, he could only carefully put away a few Yin Soul Stones, and then took out the sword trick jade slip given by Jia Yunzhen.

Jia Yunzhen said that his sword technique was a fragment, and this was true.

Zhou Yang took out the jade slip and studied it and found that the "Dayan Sword Technique" recorded in the jade slip really only had two layers, and there was no sword method in the Jindan period.

And after he studied the "Dayan Sword Technique", he realized why Jia Yunzhen said that this set of sword techniques was difficult to learn.

The sword trick is named after the word "Dayan", which actually starts by naming the essence of this set of sword tricks.

There is a saying: the number of Dayan is fifty, and its use is forty and nine.

The essence of this set of "Dayan Sword Technique" lies in the word "change", and there are more than a dozen kinds of flying sword change techniques recorded in the sword technique.

Zhou Yang had seen Jia Yunzhen cast his sword technique, and under his imperial envoy, the thirteen flying swords could not only make thirteen different changes in the combined attack, but also form a small sword formation to attack the enemy, and even the thirteen flying swords could be combined into one, bursting out with a powerful force that was enough to kill the fourth-order high-grade demon beasts.

And in fact, Jia Yunzhen hadn't gotten the true essence of this set of sword tricks yet!

The real essence of this set of "Dayan Sword Technique" is to control forty-nine flying swords to attack the enemy at the same time, and its biggest killing move is to use forty-nine flying swords to lay down the "Dayan Tiangang Sword Array", and the sword formation is one into one, which can be invincible at the same level!

However, at the same time, the forty-nine flying swords of the imperial envoy, even if it is a complete set of magic weapons, the requirements for divine consciousness and mana are extremely high, and without the strength cultivation of the Jindan period, they don't want to do this step at all.

This point is known from the fact that Jia Yunzhen is now cultivating at the fifth level of the Purple Mansion, but he can only command thirteen fourth-order lower-grade flying swords!

The most important thing is that the cultivation method of the "Dayan Tiangang Sword Array" and the third and fourth layers of the sword technique have been lost together, and there is no record in the fragments of the sword technique obtained by Jia Yunzhen.

As for Jia Yunzhen's statement that the sword trick he obtained was just a fragment, whether it was true or not, then Zhou Yang had no way of knowing.

After studying the "Great Yan Sword Technique", the more he studied, the more he couldn't put it down, and even every few days he would go to the city to test the sword with the demon beasts attacking the city protection array outside the city.

Of course, in order not to reveal his identity, he would take the initiative to avoid the immortal mountain where Jia Yunzhen was located, and specially choose some remote places to test his sword.

Compared with ordinary monks, Zhou Yang undoubtedly has many advantages in learning the "Great Yan Sword Technique", first of all, his divine sense is extremely powerful, far surpassing the monks of the same level, and secondly, the "Qianyang Immortal Sutra" he practiced is of extremely high grade, and his mana is much higher than those monks who practice ordinary exercises, and he often uses the "Qianyang Immortal Light" to refine his mana, and the quality of his mana is not comparable to that of monks of the same level.

The essence of "Dayan Sword Technique" lies in change, but if you want to comprehend the mystery of this change, it is still indispensable to comprehend and cultivate the sword moves recorded in the sword technique.

Zhou Yang's comprehension is not to say that it is at the top, there is still a middle and upper level, although the "Dayan Sword Technique" is mysterious, but he has already learned the family heirloom "Flying Star Sword Technique", and after spending about half a year, he still succeeded in getting started.

After the sword technique was introduced, when Zhou Yang made the two flying swords of "Chixuan Golden Light Sword" and "Taiyi Xuan Light Sword" at the same time, it was completely different from before.

Previously, under his control, he needed to divide two parts of mana and divine consciousness to control, but now by using the sword technique in "Dayan Sword Technique" to control the two flying swords, he is dividing one mana and divine sense into two to control the flying sword, which not only saves a lot of mana and divine sense, but also improves the flexibility of the two flying swords a lot.

When he used two flying swords to display the "Liangyi Splitting Sword Array" according to a basic sword formation change in the "Great Yan Sword Technique", the power of the two flying swords burst out, instantly strangling a third-order low-grade demon beast into several pieces.

Just strangling a third-order low-grade demon beast doesn't seem to be strong, but as long as you understand that this kind of attack move can be used as a regular means, you will know how powerful this move is!

This means that when Zhou Yang encounters the same situation as when the "Beast Tide" attacked the city in the future, as long as his mana and divine sense are not exhausted, with only two flying swords in his hand, he can instantly kill all the third-order low-grade demon beasts that have ascended to the top of the city!

The power of the first layer after the introduction of the "Dayan Sword Technique" is so powerful, which makes Zhou Yang even more determined to study this sword technique.

His current cultivation may not be able to reach the second level of the sword technique during the foundation building period, but as long as he can learn a few more sword formation change moves, it will be enough to bring his combat effectiveness to a new level.

However, the more mysterious the changes in the sword formation of "Dayan Sword Technique", the more flying swords are needed, Zhou Yang can only do it himself, and use the sword mouth of the third-order middle-grade demon beast "Sword Mouth Crane" that he killed at the beginning, and re-refine a third-order low-grade flying sword "Crane Mouth Sword".

Using high-level materials to refine low-level magic weapons can greatly increase the success rate of refining, of course, the premise is that you can refine that kind of high-level materials, and refining weapons like this, not to mention wasting materials, you can't improve your alchemy skills at all.

Therefore, Zhou Yang succeeded in refining the weapon once, and he did not have any sense of accomplishment, but only helplessness.

He has a lot of good materials on him now, but because of his own level of alchemy, he doesn't dare or want to refine them easily, so as not to waste the materials.

If this is in the Boundless Sand Sea Immortal Cultivation Realm, these materials will be handed over to the old patriarch Zhou Minghan, and there will be seven or eight more third-order magic weapons in the treasure house of the Zhou family.

For the next two years, in addition to his daily practice, Zhou Yang spent most of his time studying the "Dayan Sword Technique".

Whenever he has something to gain, he will go to the city wall to find the demon beasts attacking the city to test his sword and sharpen his sword skills.

During this period, the Great Protective Array of Zhenyue Immortal City was also closed twice, and each time the Great Array was closed, the demon beasts outside the city would launch a huge offensive.

It's just that every time a wave of demon beasts recklessly enters the city, the closed array will suddenly open again, suffocating those demon beasts that rush to the city.

After repeating this twice, when the city protection array was closed again, the demon beasts outside the city did not dare to attack the city again.

Because those high-level demon beasts have already discovered that if they launch another demon beast attack on the city, they may not even have enough power to encircle Zhenyue Immortal City in the future.

For a while, the situation was a little funny, the scene was like an old cat on a tree and an old dog on the ground, on the one hand, you have a kind of city wall, and on the other hand, you have the courage to go out of the city to fight.

When the two sides are afraid of each other, it will be difficult to fight a large-scale war.

Zhou Yang participated in the two siege battles, and won a lot, and killed seven third-order demon beasts in total, and the corpses of the demon beasts were also collected by him by finding someone to refine them into "Jingyuan Dan" as usual.

At this time, after more than two years of recuperation, the Gripen beast that had surrendered to him finally recovered from the injuries left by the battle with him and regained its strength in its heyday.

As soon as he regained his strength in his heyday, this beast was really not as honest as when he was injured before, and he actually had the will to resist Zhou Yang's behavior of putting him into the spirit beast bag and refused to enter the spirit beast bag.

Seeing this, Zhou Yang decisively took out the two swords together, and used all the "Qianyang Heavenly Sword" spells that he had re-cultivated on the body of this beast, and seriously injured him again on the spot.

Once again, it was burned into a roast chicken by the "Qianyang True Fire", and the Gygius finally understood that it could not kill this human in Zhenyue Immortal City.

It had the experience of surrendering for the first time, but this time it was faster to admit it, and as soon as it was burned by the real fire, it immediately knelt on the ground and wailed and begged Zhou Yang to take back its magical powers.

It's a pity that Zhou Yang made up his mind to punish it this time and let it have a long memory, and he waited until its feathers were about to burn out before he withdrew his magical powers.

After being beaten by him like this, the Eaglelion Beast was finally much more honest, and after eating the third-order "Jingyuan Pill" he gave, he was obediently put into the spirit beast bag to recuperate.

It's just that it doesn't know, because of its behavior of betraying the lord this time, Zhou Yang has already decided, after leaving Zhenyue Immortal City, the first place to go is where the Royal Beast Sect is located, and he must plant a "Demon Soul Contract" for this beast, so that he can rest assured that he can bring this beast back to the family.

At this time, Dong Jianping, who had been recuperating from his injuries for nearly two years and had not even participated in the two demon beast siege battles, came to the door again at this time to bring him good news.

"Brother Zhou, didn't you ask me several times when I could leave Zhenyue Immortal City? Now that the opportunity has come, the Divine Soldier Workshop needs to transport a batch of materials back to Yunzhou, and has obtained the permission of the City Lord to go out of the city, and now they are preparing to recruit some people to go out of the city as accompanying guards!"

In Zhouyang Cave's mansion, when he opened the formation to receive Dong Jianping, who came to visit, as soon as the other party opened his mouth, he said something that made him ecstatic.
