After getting the fire dragon lizard, Dong Lin and Xu Can entered the crypt where the fire dragon lizard lived together, and it was blown up by Dong Lin, and it was already chaotic, Dong Lin touched the depths of the crypt along the ruins and broken walls, and sure enough, a fire vein appeared in front of his eyes.

The fire vein was actually very similar to the underground magma on Dong Lin's side, like a small volcanic crater, and a large amount of fire aura emanated from the scorching fiery red magma flow.

As for the iron fire crystal in the memory of the fire dragon lizard, there is very little left, and it has been eaten by the fire dragon lizard, the king of big stomachs, since being chased and killed by the bald wind vulture all the way, the weak little fire dragon lizard no longer dares to easily step out of the cave.

Hungry, the little lizard swallowed the bald vulture, which had been roasted into jerky, and ate the bones and hair.

The energy rich in the body of the third-level demon beast and the demon pill was enough to raise the little lizard to the peak of the first level.

In the following days, the little fire dragon lizard ate some iron fire crystals every day according to the information in the memory that automatically emerged, until the little fire dragon lizard reached the peak of the third level, and when it was the same as the bald vulture that chased and killed him, he dared to come out, and at that time, no beast in this small valley dared to resist the coercion of the dragon beast, and the fire dragon lizard turned over and became the master, eating meat in large pieces, and never gnawing hard iron fire crystals again.

It's a pity that by this time, Tie Huojing had almost eaten, and the rest of the quality was not too high, Dong Lin didn't dislike it, and all of them were collected into the Qiankun Treasure Wheel.

In addition to the iron fire crystal, the fire dragon lizard's nest also found a lot of other ores, and a few large pieces of spirit stones, shiny, reflecting the whole nest red, very conspicuous, Dong Lin did not hesitate to put it away, it can be regarded as a small fortune.

After packing up the fire dragon lizard's nest, Dong Lin did not leave immediately, but regarded this as a place for himself to stay.

The key is the fire vein, as soon as Dong Lin got closer, he felt that the aura on his body was much more active, and when he tried to run the "Dao Classic", he found that the speed and efficiency of the operation had improved significantly.

Especially the fire aura on his body, the efficiency of absorption is doubled, how could Dong Lin give up this kind of good thing so easily, and simply let the Spirit Devouring Insect go out to explore the treasure, while he stayed to cultivate.

In fact, before the trial, Dong Lin had already reached the peak state of the late Peiyuan period through submersible cultivation, and this time when he saw the fire vein, Dong Lin couldn't help but have the idea of breaking through to the foundation building period.

Dong Lin laid a set of prohibitions outside, awakened Xu Can to help him protect the Dharma, Dong Lin chose a secluded and aura-rich room near the fire vein, and began to cultivate.

Dong Lin first tried the medium-grade Tsukujidan, and the process of taking the lower-grade Tsukujidan was similar to the last time, but this time it was more violent.

After a whole day of painful torture, the medicinal effect of Zhongpindan was completely refined by Dong Lin, but it was a pity, Dong Lin felt that he was just a little bit short of being able to break through to the foundation building period.

Although it did not reach the foundation building period, the effect of the foundation building pill is still very prominent, and the powerful medicinal power makes Dong Lin's body discharge a lot of impurities, which is black and foul-smelling, but it has made Dong Lin's physical fitness have been greatly improved.

And Dong Lin is more confident, because the effect of taking it is the same as Dong Lin's previous expectations, the Zhongpin Zhuji Dan contains more aura, the medicinal effect is faster, and the yin and yang qi contained in it has also doubled, no breakthrough is true, but it makes Dong Lin's cultivation more complete, and the real one is only one line away.

Dong Lin had a faint feeling in his heart that while the meridians had been almost impacted, as long as there was another medium-grade pill, he might be able to break through the foundation building period, but for the sake of insurance, Dong Lin still decided to take a top-grade pill to ensure that nothing went wrong.

But it was this seemingly safe move that almost put Dong Lin into a situation from which he could never recover.

The upper grade Dan is so much higher than the middle grade Dan, but in fact, there is a world of difference.

Dong Lin can say that there are a lot of Shangpindan, and it is estimated that the Shangpindan, which is eaten in the entire Manzhou, is also one of the best, and it is such an experienced old man who is a drug addict, and he is also careless.

Although Dong Lin had already estimated the efficacy of the top-grade Zhuji Pill very high in his heart, as soon as he took the top-grade pill, he immediately found that he still underestimated the power of the top-grade Xuandan.

A spiritual power dozens of times stronger than the medium-grade Zhuji Dan rushed into Dong Lin's eight veins of the Qi Sutra, and Dong Lin's cold sweat flowed all over the ground at that time.

Even if Dong Lin took the top-grade Peiyuan Dan before, its effect was four or five times higher than that of the medium-grade pill, so according to this analogy, Dong Lin felt that taking the top-grade Zhuji Dan would be ten times higher than the medium-grade at most.

It's a pity that Dong Lin ignored one of the most critical issues, that is, Pei Yuan Dan is just a yellow-level pill, and Zhuji Dan is a Xuan-level pill, don't look at it as just such a word difference, the gap is not an exaggeration to say that it is a chasm.

The difficulty of refining the top-grade Xuandan is too great, and it is estimated that in the entire Barbarian Prefecture except for Dong Lin, there is no alchemist who can pat his chest to ensure that he can refine it, and its effectiveness is naturally much greater than that of the yellow-level Dan, and it is nothing if it is dozens of times stronger, and at the advanced level, hundreds or thousands are possible.

Because the top-grade Xuandan is too scarce, there are even fewer descriptions of the top-grade Xuandan, Dong Lin did not follow the perception and rashly took the top-grade pill, and the consequences are very serious.

Almost the moment the Dan power was exerted, Dong Lin broke through to the foundation building period, and then there was a terrifying painful experience, and the excess spiritual power was filled in the meridian dantian, and Dong Lin couldn't control it at all.

Fortunately, Xu Can found out in time that with the experience of taking three Peiyuan Dan last time, Xu Can was also experienced, and quickly took the aura in Dong Lin's body to himself, and it didn't take a while for Xu Can to break through to the foundation building period, and this is not the end, a large amount of spiritual power with the exertion of the Dan effect, like a flood, constantly washed the meridians of Dong Lin and Xu Can, and one person and one ghost could not accommodate it.

As a direct user, Dong Lin needless to say, in the case of this kind of spiritual power explosion, he can only devote himself to the operation of the mental method of the "Taoist Classics", guide and control the medicinal power to wash and expand the meridians, and control the impact intensity of the spiritual power according to the situation of his own meridians.

The guidance and evacuation of the excess aura was all handed over to Xu Can to be responsible.

After all, the ghost body is not as good as the physical body, Xu Can himself can hold limited spiritual energy, Dong Lin's side is constantly transferring excess spiritual power to Xu Can, Xu Can will be in trouble, while running the exercise "Yin and Yang Jue" to drive his own spiritual power to operate, but also to distract others, thinking of passing on the excess spiritual power, the burden on the divine consciousness is very large.

In desperation, Xu Can simply transferred the spiritual power passed by Dong Lin to the incarnation, and while running the exercises himself, he also distracted the incarnation to run the "Nine Changes of the Spirit Fox" to absorb the spiritual power, under such great pressure, Xu Can's divine sense was very damaged, and his face was already pale, and now he was covered with a bleak yellow gas, and he still gritted his teeth and struggled to support it.

The house leak happened to rain overnight!

At this critical moment of cultivation, a dangerous aura suddenly came from outside the cave, which made Xu Can, who was already struggling, shocked!
