This wisp of medicinal liquid is a kind of left-path material refined from hundreds of strange things, and in the left-path blood order, Lin Feng can use this wisp of medicinal liquid to perform an ancient trick called "Extraction Technique"!

The liquid medicine penetrated into the jade plate, and soon penetrated every subtle place, the wisp of blood that Lin Feng had punched in before had already fused with the original magic in the jade card, and was firmly solidified in the inner layer of the jade card, but under the erosion of this wisp of medicinal liquid, it quickly softened and fluffed up!

As Lin Feng continued to inject the magic formula, the spiritual power of the medicinal liquid continued to exert miraculous effects, causing Lin Feng's wisps of blood to continue to separate from the deep layers of the jade plate, until Zuihou completely got rid of the restrictions of the original blood oath and floated up from the jade plate!

The wisps of blood that floated out were directly sucked back into Lin Feng's body, he originally wanted to use the Dome Mastiff Blood Yuan to hide from the sky and the sea, but the trickery in the Left Dao Blood Order was even more magical than the previous Left Dao fragment, and the extraction technique that Lin Feng had just performed was one of the magical tricks recorded in the Left Dao Blood Order.

The refining of the medicinal liquid required for the Extraction Technique is extremely difficult, and the materials required are extremely complex, Lin Feng has not been able to collect them all after months of collecting in Daoji City, but in the ruins of the Left Dao Gate in the painting, the few storage bags he obtained have completed his old grudge.

With the help of this unique potion, the Extraction Technique can extract the solidified blood element from the Blood Oath again, and the amount of liquid medicine used is also different according to the strength of the Blood Oath, and the larger the number of liquids, the higher the mana required.

The Jin Zhen clan's entry blood oath is the most loose one, because Lin Feng is a guest disciple, it can't be too many restrictions on him, and the only restriction of the Jin Zhen clan is that he must change the Demon Sect exercises, and use the magic trick to preset it in the jade card in advance, although the content of the blood oath is excessive, but the blood oath itself is relatively weak, Lin Feng can easily dissolve it with the extraction technique.

After the bloodshot was withdrawn by Lin Feng, Lin Feng injected a trick into the jade card, and the wisp of medicinal liquid gradually condensed, and finally turned into a blood-red color, fusing with the magic trick in the jade card, replacing Lin Feng's original bloodshot, making it look flawless!

After the completion of the extraction technique, the mana in Lin Feng's body was fully sixty percent, and there was no need to consume the best spirit pill in the cave, he absorbed the spiritual energy step by step to recover, and after a long meditation, he only opened his eyes on the second day.

After carefully examining the guest jade plate of the Jin Zhen clan several times, he really didn't see any flaws, so Lin Feng put it away, with this jade card, maybe when Bu Yuecheng was really attacked by demon beasts and couldn't defend it, Lin Feng was able to use the Jin Zhen clan to escape from danger.

In the next few days, Lin Feng selected a batch of magic weapons obtained by killing other monks, replaced the divine sense imprint in them, so that they could be used for his own use, and then refined a large number of spirit runes, about half a month later, Bu Yuecheng suddenly heard a violent attack.

The roar and vibration continued to come from outside the city, Lin Feng immediately pushed open the gate of the cave mansion, his divine sense quickly glanced around, his face suddenly changed, and then he packed up all the materials in the cave mansion, and then flew out of the cave mansion and came to Fang City.

Bu Yue City was already in chaos at this time, and there were monks from all sides who continued to attack outside the city, but they were soon forced back by a large number of demon beasts, Lin Feng saw the sudden increase in the number of demon beasts, and the change in the situation in the dark path was even worse than he expected.

The guest jade card of the Jin Zhen clan also sent a summoning message at this time, Lin Feng followed the guidance of the jade card, and quickly found a open valley in Buyue City, where the portal of the Jin Zhen clan was located, and at this time, a large number of outer disciples and guest disciples gathered in the valley.

The Yuan Infant Ancestor of the Jin Zhen Clan, who appeared in front of Lin Feng and other foreign monks for the first time, bluntly expressed his intentions, that is, he was ready to abandon Buyue City at any time and move to the center of the Miao Frontier.

This kind of ending has long been expected by many monks, but the foreign monks did not expect that the ancestor of Jin Zhen would be open and honest to them and clearly point out his intention to abandon the city, which made him feel good in the hearts of everyone, and because of this, he won the trust of some outer disciples.

After that, Jin Zhen Ancestor pointed out again that in the open valley where the Jin Zhen clan is located, there is a passage that can directly lead to the outside of Bu Yue City, when Bu Yue City is lost, when a large group of demon beasts break through the city protection array, Bu Yue City will fall into emptiness, and all the disciples of the Jin Zhen clan will escape from the secret passage of the open valley.

This piece of news came out of the mouth of the Jin Zhen Ancestor, which once again made all the disciples ecstatic, at least for now, the conditions of the Jin Zhen clan were very conducive to escape, compared to the other cultivators in Bu Yue City, joining the Jin Zhen clan was indeed a wise choice.

Jin Zhen Ancestor bought people's hearts with the grace of escape, and then began to put forward his conditions, once he escaped from Buyue City, all disciples must be transferred in a unified manner according to the route he specified, and all monks who acted without permission would be intercepted or expelled.

Zuihou, Jin Zhen Ancestor clearly pointed out that when all foreign disciples retreated, if they could receive and complete the tasks assigned by him, after arriving in the interior of the Miao Territory to repel the demon beasts, they would give them the exercises of the Demon Sect.

Zuihou is completely set up for the stronger monks of the Dan period, and all the disciples who join the Jin Zhen clan will inevitably be restricted by the blood oath, so no matter who it is, they must transfer to the cultivation of magic skills in the future, otherwise they will be restricted by the blood oath, and it is difficult to find rare superior exercises when transferring to the cultivation of magic skills, and this condition of the Jin Zhen Ancestor is undoubtedly extremely tempting.

The Jin Zhen Ancestor explained his intention in a simple and uncomplicated manner, and then turned around and left the open valley, and then several monks of the Jin Zhen clan in the late stage of the Jiedan classified all the recruited outer disciples and guest disciples according to different cultivation levels, and then were assigned to the corresponding clusters.

Lin Feng's cluster was led by Jin Zhengyu, there were a total of fourteen monks in this group, except for Jin Zhengyu and the other three, the other ten were all guest elders, but Lin Feng was the only one who cultivated in the later stage of the Dan.

Lin Feng noticed that there were about fifty people recruited into the other Jiedan stage monks in the Jin Zhen clan, and they were divided into five batches, each batch was about ten people, Jin Zhengyu led only one of them, and the other four batches were also led by the Jin Zhen clan's own Jiedan stage monks.

The Jin Zhen clan's own disciples in the Dan period, the total number is only about thirty, and more than half of the number is mixed with five groups of foreign monks in the Dan period, and the other part leads a huge number of disciples below the foundation building period, and after each of them clarifies the cluster to which they belong, the ancestor of the Jin Zhen clan issued the first order to them to defend the city.
