"So you want me to try it, see if I can refine the elixir and open the cave for you, so that I can go in and get the treasure, right?" Zhou Lin looked at Su Wen with a smile and said slowly.

"Yes, and we have already collected all the pills that we need on the single side!Because it is at least a second-grade pill, and the Danfang has a high requirement for the year of the elixir! Therefore, we have used all the strength of the Wangyuan City Division, and we have only collected seven copies!"

"The master only needs to refine one pill, and the excess materials are considered to be given to the master, and we will pay the price of 50,000 spirit crystals, if the master uses up the seven materials and fails to refine the pill, then we can only consider ourselves unlucky!" Su Wen said sincerely.

"Okay! I agreed! But I still have one request, when I open the cave, I must be present in person, and I will take away anything related to the pill in the cave, you should have no opinion, after all, you don't have an alchemist at all!" Since there is no risk, Zhou Lin thought about it and agreed.

"This ······ Okay! Then I'll unilaterally promise the master first, and I'll try my best to convince our sect master! By the way, for the sake of insurance, let's take the master to the cave to see the stone wall first, so as not to miss anything!" Su Wen thought about it, and there was indeed no alchemist in the door, so he gritted his teeth and agreed.

"That's very good!" Zhou Lin had long wanted to see what this Yuan Dan Realm place was like.

As Su Wen walked out of the city, about half an hour's effort, the two came to a wasteland outside the city, but it seemed that they had gone a little far, Zhou Lin couldn't help but look in the direction of Zhou's house twice, and saw the thick fog from a distance, and some of the worries in his heart also disappeared a little.

Su Wen found that Zhou Lin's eyes kept looking in that direction, so he naturally glanced at it as well, and muttered in his mouth: It's really strange over there, I don't know when a heavy fog will blow, I heard that there are cultivators who have an air building layer and can't blow it away with spells.

I followed Su Wen for a short while, but came to a swamp, which is strange, the whole wasteland has no water source at all, where did the swamp come from, but found that Su Wen had already covered his whole body with his vitality, and said to him: "Come, this time I have to make you feel a little wronged, the cave is under this swamp, and it was also discovered after the disciples of our sect accidentally fell into it." ”

"Oh, yes, okay, but for the sake of the treasure of the Yuan Dan Realm, let's be dirty!" Although he said this, a trace of suspicion flashed in Zhou Lin's eyes.

Covering his whole body with Yuan Li, he jumped into the swamp with Su Wen, and continued to swim down for about a zhang, and finally found a hole that seemed to be blasted open by some brute force, and even around the cave entrance, he could still feel the fluctuations of the remnants of the prohibition!

After swimming into the entrance of the cave, they found that there was a formation to isolate the water inside, and the two walked in for a while, and finally saw the stone wall that Su Wen said, only to see that in the plain and unremarkable stone wall, there was a small rectangular and delicate box, and there was indeed a hole the size of a pill on the box.

Take a closer look, the stone wall is indeed densely written with a pill prescription and alchemy precautions, and it is clearly stated that this pill must be refined and put into the hole before the stone door can be opened, and forcibly breaking the door will destroy everything in the cave, because this pill is prepared by the owner of the cave himself, and I hope that only those who are destined for alchemy can get his inheritance.

However, seeing this, the suspicion in Zhou Lin's heart became heavier, so he took a closer look at Dan Fang.

Poison Stripe Pill

Three strains of 400-year-old sharptooth grass

Two hundred years of tiger heart leaves one or two

First-level spirit beast arrow snake venom

······

A lot of materials, whether it is the main medicine or the rest of the auxiliary elixirs, are highly poisonous!

This is a poison pill!

However, according to the refining materials, the difficulty of this pill is indeed among the second-grade pills, and it is much more difficult than the Huoyun Pill that Zhou Lin is refining now, but since the Great Sword Sect has collected as many as seven parts of the materials, refining the pill is naturally not a problem.

Keeping this Dan recipe and the refining experience of this very likely Yuan Dan Realm master in mind, Zhou Lin nodded to Su Wen and signaled that he could go back, but when the two of them left, Zhou Lin still looked at the stone wall with suspicious eyes, and his divine sense was even more concentrated, but unfortunately he didn't seem to find any useful news, so he shrugged helplessly, turned around and left.

However, after the two left, only a roar was heard, and the stone wall actually separated itself, and more than ten people walked out of it, among which the inconspicuous one was wearing a gray robe······

"Fish, hooked······" A faint voice echoed through the cave.

Zhou Lin and Su Wen returned to the Great Sword Gate, and after some discussion, in order to prevent this cave mansion that was not easy to find from being preempted by others, Zhou Lin finally promised Su Wen that the elixir would be refined within ten days, and accepted the seven elixirs, and Zhou Lin returned to the mansion of Tongsheng Commercial Bank.

As soon as I returned to Tongsheng Commercial Bank, I felt that compared with the Great Sword Gate, it was basically heaven and earth, maybe the Great Sword Gate was really an ascetic, but it may be that Tongsheng Commercial House deliberately curried favor with Zhou Lin, and actually made the alchemy room magnificent, and sent someone to clean it regularly, which really made Zhou Lin admire this Guo Ling a little.

The poison pill is a branch of the Fadan, but it is more insidious, after all, the poison pill does not require the use of a large amount of yuan power, it only needs to be sacrificed directly like a secret weapon, therefore, Zhou Lin also failed three times at the beginning, and after summing up the experience, he finally succeeded in refining a poison pattern pill for the fourth time, and originally wanted to refine it all in one go, but found that the divine consciousness and yuan power actually had symptoms of overdraft, and he was too obsessed with alchemy, and he didn't find such a serious thing.

simply went back to the room and slept first, got up the next day to continue practicing, and succeeded in two pills, and once failed because of the heat problem when condensing the pill, in order to prevent the cave from being discovered in advance, Zhou Lin directly used a transmission note to let Su Wenming go with him every day, so as not to have a long night and many dreams.

Su Wen and his group, who received the transmission note, naturally waited at the door of Tongsheng Commercial Bank early in the morning, as if they were afraid of trouble, but they did not go in directly, Zhou Lin came out of the trading house, and when he saw Su Wen and them, he was also taken aback.

I saw seven big men standing behind Su Wen, each with a big sword behind his back, although the cultivation is all a layer of Qi Layer, but standing together gives people a solemn atmosphere, although it is appropriate to enter autumn, but everyone is dressed in short shirts, and even the passing crowd does not dare to approach too much.

When Su Wen saw Zhou Lin coming out, he naturally greeted him, and the two nodded, in order not to attract attention, Su Wen asked his subordinates and Zhou Lin to go out of the city separately, so as not to attract the attention of people with hearts.

An hour later, everyone was already standing in front of the stone wall, Zhou Lin carefully took the poison pattern pill in the storage ring into his hand, and under the gaze of Su Wen and the seven people behind him, he was about to put the pill into the hole in the box, Zhou Lin's divine consciousness was released consciously or unconsciously, as if he was looking for something.

"Poof!"

The pill rolled into the hole, but the sound was as if it had been thrown into the water, and the nine pairs of eyes stared intently at the stone wall, the only difference was that Zhou Lin's whole body was running with Yuan Force, and he thought in his heart that no matter what the emergency, he would escape from this cave and rush out of the swamp as soon as possible.

"Boom!"

I saw that the box slowly shrank into the stone wall, and the stone wall seemed to feel something, and slowly opened like a door.

It worked?!

"The third child stays, in case there are other special circumstances, the rest of the others and Master Zhou will go in with me! The cave should not be too big, if it doesn't come out in half an hour, you will go and inform the branch master!" Su Wen seemed to have some experience in taking treasures, so he called someone to stay at the door, and took Zhou Lin and the others in.

"Brother Su Wen has arranged things very properly, but Brother Su Wen, there is one thing I still don't understand, I heard that your sect is already the seventh layer of the Qi Formation Layer, why not let him bring you directly to get the treasure, isn't it more secure?"

"This master doesn't know anything, originally on the importance of the Yuan Dan Realm Cave Mansion, it should have been our master in person, but it seems that the head of the Li family in Xicheng seems to have something important to discuss, and he has been talking in the restaurant every day for ······the past two days."

"Bang!"

I heard a loud bang, and the light behind me disappeared completely!

This is, the stone gate is closed!

Didn't people watch the entrance of the cave, could it be that there was a conflict outside?

Still, this stone gate was originally a mechanism!

At this moment, a sneer came from his ears.

"Hehehe, I'm sorry, whether it's all of you from the Great Sword Sect or Master Zhou, who has been going smoothly recently, you all have to hand over your lives here today!"

Zhou Lin contracted all his divine senses, carefully searched for the source of the pronunciation of the voice, and found it!

Almost as if instinctively, he instantly took out the Yutian Bow from the storage ring and shot out a fine steel arrow, under the operation of Yuan Li, the iron arrow rotated at high speed, and slashed through the air like a meteor!

The whole process takes less than two seconds!

"Poof!"

The sound of an arrow piercing flesh is heard.

"Ahh

A black shadow fell to the ground, Su Wen just recovered from the previous shock, and hurriedly stepped forward to turn the figure over, opened the mask, Su Wen actually knew!

"You're that junior, aren't you the one who discovered this cave? Who are you?"

It's a pity that the junior who was shot in the heart by an arrow coated with arrow snake venom couldn't answer his question and was completely dead.
