The root cause of the elixir's malaise was already obvious, and Fu Dongchuan and the three of them couldn't help but have a good impression of Lin Feng, but if they wanted to save this elixir, Fu Dongchuan and the three of them still had no clue.

Lin Feng said to them: "If I'm not mistaken, this miscellaneous qi contained in the soil layer of the medicine garden should be dissolved by the lonely cold water! Although it is very weak, it has fatal damage to the elixir, if it is not cleared in time, not only will the elixir in it not survive, but even this medicine garden will be destroyed in one fell swoop!"

Fu Dongchuan and the three of them were startled at the same time, their expressions became extremely strange, although no one spoke, but a tacit understanding had been expressed through their expressions, it was obvious that what Lin Feng had just said about the Lonely Cold Water had touched them, and they could no longer deny that the root cause of the death of the elixir was the Lonely Cold Water, but they had not discovered it before.

The expressions of Fu Dongchuan and the three of them, Lin Feng naturally saw it in his eyes, although he didn't understand what the three of them were thinking, but it was obvious that when Lin Feng proposed the lonely cold water, the three of them immediately behaved very vigilantly, fortunately, Lin Feng's cultivation was only in the foundation building period realm, otherwise, he was a foreign monk, I am afraid it would cause Fu Dongchuan and the three of them to be extremely nervous!

After being silent for a long time, Fu Dongchuan looked at Lin Feng and said, "It is true that the lonely cold water caused the elixir to die, your herb cultivation technique is really extraordinary, but next, is there a way to cure these elixirs?"

Lin Feng said calmly: "The soil layer of the entire medicine garden has been penetrated by the miscellaneous gas formed by the lonely cold water, although the number is very small, but it is extremely deadly, and as time goes by, the situation will get worse and worse, the only way at present is to clean up the leylines of the medicine garden, but the probability of success should not exceed thirty percent." ”

Fu Dongchuan was slightly stunned: "Cleaning up the leylines?" can expel the miscellaneous qi formed by the lonely cold water?"

Lin Feng nodded slightly: "Yes, it's just that it's extremely difficult, the lonely cold water can penetrate into the spiritual energy, it is not something that can be done overnight, this penetration is extremely slow, I must find out the situation of the leylines under the medicine garden, and find the source of the lonely cold water, and find a way to block it out of the spiritual veins." ”

As soon as Lin Feng said this, Fu Dongchuan's faces changed slightly again, and after a long time, Fu Dongchuan said slowly: "This batch of elixirs must be saved, otherwise, Yidaomen will face a great dilemma." ”

Bai Yi hurriedly said: "However, this junior just said that the success rate of being able to clear out the lonely cold water is less than thirty percent, and if he is allowed to enter the spiritual veins under the medicine garden, this is probably a little inappropriate......

Fu Dongchuan interrupted him and said: "There is no other way, a batch of these elixirs is about to be ripe, the ancestors of Yidaomen urgently need to use it, you and me, the peers of the Dan stage, must quickly break through the bottleneck, even if there is only a thirty percent chance, you must give it a try." ”

Bai Yi hesitated: "However, the spiritual veins and the lonely cold water below ......"

Fu Dongchuan quickly waved his hand to Bai Yi, "That's it!", then turned his head and asked Lin Feng: "What is the name of this little friend?" From now on, you are a foreign disciple of Yidaomen, but this is only temporary, when you save this batch of elixirs, I will immediately promote you to an inner disciple, and personally serve as your preaching master." ”

Lin Feng hurriedly said: "Senior Lin Feng, just to avoid the war, I want to rely on my little skill to come to Yidaomen to seek a place to cultivate with peace of mind, and I don't have any other luxury, and I don't dare to think of becoming a respected disciple of the senior in charge." ”

Fu Dongchuan's face has been tepid: "Since you want to join the Yidaomen, don't be arrogant, the Yidaomen is different from other sects, as long as you become a disciple of the inner sect, you don't need to be burdened by trivial matters, just concentrate on cultivating, I Yidaomen has many unique killing techniques outside the main exercises, which can greatly improve your actual combat power, the higher your status, the greater the possibility of getting the unique killing technique, and you will also get the careful guidance of the preaching teacher." ”

Lin Feng's face moved, thinking that the Yidao Sect was really different from other sects, the disciples of most sects could only get the main cultivation method from the teacher at most, and the subsequent cultivation depended on himself, and the master could not and did not have time to guide the disciple's cultivation, and the unique killing technique that Fu Dongchuan said aroused Lin Feng's curiosity even more.

When Lin Feng's heart was moved, Fu Dongchuan said solemnly: "From now on, you have officially become a disciple of the Yidao Sect, without my instructions, you must not leave the Yidaomen for half a step at will, otherwise, the two Sect Protector Spirit Beasts outside the door will kill all the disciples who leave without permission!"

Lin Fenglian claimed that it was, and Fu Dongchuan said with a majestic face: "Now, I will take you to see the spiritual veins under this medicine garden, which involves the core secret of the Yidao Sect, and all the foreign monks who have seen this secret have all undergone strict review.

Only monks who have passed the soul search verification can become disciples of Yidaomen, and those foreign spies who tried to explore the secrets of Yidaomen and plot against Yidaomen were all killed here after soul searching.

You are the only foreign monk who has not gone through the soul search verification and entered the inner core of the Yidao Gate, because after the soul search, it will cause a lot of damage to the sea of knowledge, and the recovery will be protracted, and these elixirs are in urgent need of treatment, so it is impossible to conduct a soul search verification on you, but if you have two hearts for the Yidao Gate, you will not be able to avoid being killed!"

Lin Feng was secretly frightened, if he really wanted to be searched for souls, many secrets that could not be passed on would inevitably be lost, fortunately he came at the right time, Yidaomen was most concerned about treating those elixirs as soon as possible at this time, and Lin Feng's soul search verification could only be stopped, and what puzzled Lin Feng was that exploring the leylines was not a secret thing, but in Yidaomen's opinion, it seemed to be very cautious.

When Lin Feng was suspicious in his heart, Fu Dongchuan had already used his spiritual power, flew up from the medicine garden, and flew towards the main hall outside the valley, Bai Yi and Zi Jiuqing followed closely with Lin Feng, and landed outside the main hall within a few breaths.

After Lin Feng followed Fu Dongchuan and the three of them into the main hall, he stood down in a circular area in the center of the main hall, as soon as Lin Feng stood firmly, Fu Dongchuan had already played a trick, Lin Feng only felt dizzy, and the ground suddenly fell at an extremely fast speed, bringing the four people above to the underground!

The prohibition that brought the four people underground turned out to be a cloud ladder thousands of zhang long! It's just that the top of the cloud ladder connects to the ground of the main hall, and the thickness can reach tens of zhang deep, and its existence cannot be seen through from the main hall at all.

The ladder stretched automatically, as fast as thunder, sending the four of them to the depth of the ground thousands of feet below, and then returned to the ground, and joined the ground of the main hall again, without any flaws.
