A few minutes later, the three Yin Demons returned to their original form, and the mass of souls was gone. However, the Yin Evil that was devoured was only a little larger than the original, and it was completely disproportionate to the strength of that mass of souls. You must know that after devouring the soul of the petrified lizard last time, Yin Sha suddenly changed from the size of a mung bean to the size of a broad bean.

"Damn!, so this little bit of spiritual energy!?" Su Ze was immediately disappointed, and couldn't help but look up to the sky and sigh: "It seems that the book is right, there is really nothing wrong with picking up cheap!"

Forget it, it's better than nothing, anyway, there are 11 more, no matter how thin the mosquito legs are, it's also meat. After about twenty minutes, the souls of the battlefield were swept away by the Shadows. Nourished by the souls of 12 petrified lizards, they were restored to the size of 2 broad beans, about half of what they used to be.

Su Xue secretly thought about it and felt depressed: "According to this calculation, the spiritual energy contained in the soul obtained by picking up cheap is only about 5% of the normal. It's really not cost-effective, no wonder the senior said that he didn't make a big deal when he picked up the cheap......"

After putting away the yin evil, Su Xue did not rush to collect "fairy mushrooms" and collect the corpses of petrified lizards, but came to the cliff where the flying dragon collected stones just now. The actions of those flying dragons just now made him very curious.

Su Xue came to the cliff and looked at it, and was a little surprised: "Damn, there are so many traces, are these stones still treasures?"

There were countless marks on the cliff, large and small, from paw prints to hoof prints, as well as bite marks left by various tooth shapes, and some unrecognizable marks, many of which animals had left their marks on.

"Da Mao, what are you doing? Da Mao!" Su Xue was observing, but suddenly saw that the three dogs actually ran to the cliff and ate those stones.

The wyvern had just sprinkled urine near the cliff, and the warning of this high-ranking creature was so strong that the dogs were scared. If Su Ze hadn't taken the lead, I'm afraid they wouldn't have crossed the "urine cordon" when they were killed.

Although loyal to their owners, the dogs can barely suppress their instinctive fear of superior creatures. But they all had their tails between them, their ears drooping, and their bodies couldn't stop shaking, like frightened birds.

Unexpectedly, as soon as they arrived at the cliff, these dogs were in high spirits, ran over with a smoke, and gnawed those stones vigorously. They purr excitedly as they eat.

"What kind of good thing is this stone, why is it all of them so virtuous?"

Curious, Su Xue picked up the saber and picked it up a little on the stone wall, this kind of stone is indeed not hard, and it is estimated that it is no different from sandstone. If you look closely, you can see that the stone is made up of many fine crystals, as well as some gravel and other debris.

Su Ze picked up a small piece of relatively clean stone and licked it lightly with his tongue......

....................................................................................

"Bah, bah~~~" He immediately spat and quickly drank saliva to rinse his mouth. Immediately, he smiled bitterly and said, "Damn, I thought it was some kind of treasure, it turned out to be rock salt...... Phew~~, the quality of this rock salt is not very good......"

That's right, these stones are rock salt! Moreover, the purity of this rock salt is not high, and there is a slight bitter taste.

For most wild animals, salt in their food alone is not enough to meet their physical needs. They usually look for soil and rocks that contain salt and eat them to replenish the salt. Therefore, in the wild, animals are sometimes seen gnawing on dirt and stones, and even domestic animals sometimes gnawing on mud.

Therefore, natural salt ponds are a rare treasure for wildlife. Its importance is not much worse than the status of oil fields and mineral deposits on the earth in the hearts of human beings. In the wild, near natural salt ponds, there are often bloody clashes between animals fighting for control of the area.

"Those petrified lizards are really unlucky, this is probably a crime...... Su Ze is now basically sure that the battle between the flying dragon and the lizard was the reason for the previous battle, it turned out to be a battle for the salt field.

At first, Su Xue was still strange, generally speaking, there are few conflicts between predators and predators, except for fighting for food and territory. Even if the dragons are fierce enough, there is no reason to prey on such a tough animal as the petrified lizard, and there are no other targets that are easier to bully nearby. It's not about fighting monsters in the game to brush up on experience points.,Carnivores are all animals that are easy to bully.,They'll never mess with their peers.。

He estimated that this natural salt field should be occupied by petrified lizards in front of it, and it can be seen from the traces on the rock wall that they have not occupied it for a long time, and it is estimated that it will not exceed a year. But their good days didn't last long, and this place was discovered by the two-legged wyverns, and the result was naturally a tragedy.

It may be that the terrain here is not suitable for the Wyverns to live in, so they just ran around to enclose the ground, and had no plans to move.

However, there is still a question here.

Su Ze looked at the dogs with some confusion: "Hey, you follow Lao Tzu every day to eat and drink spicy food, there should be no shortage of salt, why are you still interested in these low-quality rock salts?"

These stones are probably not just as simple as rock salt! Just now, Su Ze felt that the taste of these rock salts was a little weak, and there should be some other things mixed in them. However, Su Ze's tongue was not yet used as a laboratory instrument, and he couldn't be sure what it was, so he had to take some samples and take them away.

............................................................................................................

Su Ze took the dogs who had eaten enough salt and began to collect the loot.

"Malagobi, how can these fairy mushrooms grow in this kind of bird place!" Su Xue, who was collecting fairy mushrooms, suddenly scolded with a gloomy face.

This can't be blamed for his overreaction, anyone who catches a piece of while picking mushrooms will definitely scream and scold like him.

Just now he saw a piece of mushrooms that grew very luxuriantly, and even the smallest one was the size of a rice bowl. The last time he picked mushrooms, there were only a handful of mushrooms of this size. After repeated experiments, Su Ze found that the bigger the head, the better the quality and the more umami.

There are so many high-quality fairy mushrooms here, Su Ze was overjoyed and immediately started to collect them, but he didn't expect to touch a piece of when he went down for the first time.

This made Su Xue cry and laugh, and at the same time, he couldn't help but think: Could it be that this fairy mushroom still needs the feces of a petrified lizard to grow?

After careful observation, Su Xue had to accept the facts with an embarrassed face. His guess was completely correct: wherever the mushroom grows, the feces of the petrified lizard have been found, and the fresher the feces, the better the growth of the mushrooms.

Looks like I'm going to have to be a manure digger again. Su Ze thought depressedly. It is no wonder that the growth of the transplanted fairy mushrooms in the past is miserable, and it turns out that the key factor is the lack of petrified lizard feces.
