At the beginning of the road, the two of them walked directly, without stopping at all, and the place near the border was turned over countless times, so naturally there would be no sand crystals.

After walking for nearly two kilometers, they stopped, and Yuan Yibiao took out a shovel-shaped magic weapon out of nowhere, and said to Li Shengtian: "Brother Li, let's look around here, and then go inside, it will take a lot of effort!"

As he spoke, he began to rummage on the ground.

Li Shengtian watched Yuan Yibiao digging aimlessly, and wondered: "Brother Yuan, is this sand crystal buried very deep under the red sand, why don't you use your divine sense to search for it, and then start digging?"

Yuan Yibiao smiled bitterly when he heard this: "It's not because this red sand is highly toxic, the divine consciousness falls on it, most of it is cut off by the poison, it is difficult to enter it, and after a long time, it will also cause damage to the divine consciousness, so everyone adopts this stupid method, although the efficiency is low, but it is better to be safe." ”

As soon as he entered it, he felt a foul air filling the underground red sand world, blocking his divine sense, and taking the opportunity to erode that divine sense, completely destroying it in just a breath, and even spreading poisonous gas along the divine consciousness quickly towards Li Shengtian's sea of consciousness, Li Shengtian hurriedly endured the pain to cut off the divine consciousness, which avoided the ensuing poisonous gas.

This poisonous gas was really powerful, Li Shengtian was surprised in his heart, and he stood in place for a while and forgot to move forward.

"Brother Li, what's wrong?" asked Yuan Yibiao on the side.

"It's okay, under the temptation of the divine sense, some of the power of the divine sense was lost. By the way, Brother Yuan, isn't there a cure for the poison of this red sand?" Li Shengtian came back to his senses from his surprise.

"Of course, as long as you take a Wei Ti Dan, Wei Ti Dan can not only detoxify erysipelas, but also dissolve the poison of red sand here. However, that elixir is too expensive for a minor monk like us to afford. Yuan Yibiao sighed.

Li Shengtian said in his heart, if he can refine the Wei Body Pill, then the danger of crossing the Red Sand Desperate Realm will undoubtedly be reduced a lot, but he does not have the corresponding Dan formula, I don't know if Yuan Yibiao knows if he knows, "Brother Yuan, I don't know if you know what spirit herbs the Wei Body Pill is refined, maybe I can try to refine some, so that we can be more handy here." ”

Yuan Yibiao said regretfully: "Brother Li, I only know what spirit grasses are needed to refine this pill, but I don't know the proportion of spirit grasses in it, I'm afraid it's useless." ”

Li Shengtian said happily: "It's okay, you just need to tell me the name of the spirit grass, and the rest will be studied slowly." ”

At that moment, Yuan Yibiao memorized all the spiritual herbs he knew, blood orchids, thousand feather leaves, wisteria roots, etc., a total of twenty kinds of medicinal materials, including sand crystals.

Yuan Yibiao only said these medicinal materials once, and Li Shengtian firmly remembered that he had all the medicinal materials, and the medicine garden in the Xuanhuang Pagoda had collected all the spiritual herbs he could encounter over the years, and these accumulations were not a joke. However, planting these rare spirit grasses also cost Li Shengtian a lot of spirit stone resources, and there is nothing wrong with this gain or loss.

In the next few days, the two of them searched for sand crystals in the red sand land during the day, and stayed on the mound ten miles away from the edge of desperation at night, Li Shengtian studied the refining of the Wei Ti Dan in his tent every night, and in the first few days, Yuan Yibiao would always hear the sound of a bang coming from Li Shengtian's tent, and then there was no sound, and he didn't know how Li Shengtian's Wei Ti Dan was progressing.

It has been eight days since they came to the Red Sand Desperate Situation, and they have also harvested five sand crystals, of which Yuan Yibiao's two have all contributed to Li Shengtian, in Li Shengtian's words, it is to invest first, and he will give him a big gift later.

In fact, even if there is no compensation, Yuan Yibiao has no intention of asking for it, after all, he owes Li Shengtian too much kindness, and I am afraid that he will not be able to pay it off in this life.

On the night of the tenth day, a strong scent of danxiang came from Li Shengtian's tent, and then the sound of Li Shengtian's laughter was heard.

Yuan Yibiao got up from his sleep and came outside the tent, he saw Li Shengtian laughing happily at the sky, seeing this, Yuan Yibiao understood, "Brother Li is really a good skill, but the Wei Ti Dan has been refined?"

Li Shengtian took out a white jade bottle and handed it to him, "Yes, the Wei Ti Pill has finally been successfully refined, Brother Yuan, look at this pill!"

Although he had already guessed the result, when Yuan Yibiao took the jade bottle in his hand and carefully looked at the three pills that emitted a soft light in the bottle, he still couldn't believe it in his heart, Li Shengtian's Dan Dao level was so high, I am afraid that he had already reached level seven or above, and the spiritual grass required for this health pill was all rare in the world, Li Shengtian didn't know how many spiritual herbs he used in order to refine the pill, he couldn't imagine what kind of wealth Li Shengtian had, so he had such courage.

He stared blankly at the vial, speechless.

"Try it, Brother Yuan, since we have the Wei Ti Dan, we are not afraid of the poison of the red sand, let's go, let's go to the red sand desperate situation to test it now!" Li Shengtian was so excited that he couldn't sleep at all, put the tent into the storage bag, and headed towards the land of red sand.

Sure enough, after taking the Wei Ti Pill, as soon as the poisonous gas in the desperate situation entered the body, it was dissolved, even if the two of them did not use the True Yuan to protect the body, they were still unscathed, and their divine sense burrowed into the sand, easily getting rid of the erosion of the poisonous gas in it, and extending to a depth of several meters.

After taking the Wei Ti Dan, Li Shengtian felt that all the pores of his body were dilated, and the wisps of gray substance were expelled from the pores, which was erysipelas in the body. Li Shengtian secretly said Fortunately, he knew about the Wei Ti Dan at this time, and he successfully refined it, and took it, it turned out that there were so many erysipelas accumulated in his body over the years, if he didn't cure it again, his cultivation path would become more and more difficult, until in the end, there was no hope of promotion.

"Brother Li, my divine sense can see three meters deep underneath, ah, a lot of sand crystals!" Yuan Yibiao was still saying happily one second, and the next second he screamed.

Li Shengtian seemed a lot calmer, he had long expected that under the red sand was definitely a treasure land that few people explored, and now it seems that this is the case, this time, he has to dig it well, otherwise he will be sorry for the hard work he has paid for these days.

One, two, three......

Their storage bag contained more than a hundred sand crystals in just one hour, and these harvests made Yuan Yibiao's eyes light up, as if he saw a way to make a fortune, and he didn't even bother to say anything, just digging sand crystals vigorously, like a gold miner.

The medicinal effect of a Guardian Pill could only last for a day, and when they left, the harvest of sand crystals had reached a terrifying thousand.

"Brother Yuan, I plan to leave tomorrow, what are your plans?" said Li Shengtian sitting by the fire on the mound.

"Brother Li, have you really decided to cross the Red Sand Desperate Realm, although you have the Wei Ti Dan, it is still very dangerous, but I believe in your ability! As for me, since Brother Li is leaving tomorrow, my brother will accept it when he sees it, so as not to be coveted by some villains. Yuan Yibiao groaned.

At dawn, Li Shengtian and Yuan Yibiao bid farewell to each other and embarked on their respective journeys.
