So that the thing is crystallized.

What exactly is this crystal? No one can say for sure, anyway, the pre-civilizations only mentioned stones, all kinds of stones that would occur in animals and people.

Such as gallstones, kidney stones!

Crystallized? I don't know if that era was not faked, but whether the relics that really came naturally were counted?

Tang Ling is not a science and technology scholar after all, although he is curious and explores knowledge, but after all, he does not have the time and environment to study it thoroughly.

It can only be said that crystals are unique to this era, and they generally appear in the major muscles of the heart.

Tang Ling hadn't really seen the crystal, but according to the query information, Tang Ling learned that this kind of blood-red crystal with a hint of purple was not abrupt, just like a stone embedded in the heart.

It's more like growing in the heart and connecting with the blood of the heart.

The major cardiacis muscle around the crystals also changes and becomes tougher, and the closer you get to the crystals, the more you become more prominent.

It feels like the cells of the heart are slowly mutating and eventually forming crystals.

And what is the essence of crystallization? Tang Ling still doesn't know, and he doesn't know if the cells can be observed in it?

However, it makes sense for such a change to occur, otherwise the heart of the flesh and blood of the previous civilization is simply not enough to support the strength, speed, and so on of modern people...

At least that's true for humans, at least the stronger the creatures, the more likely they are to crystallize.

As for insects... Tang Ling thought about it as he bandaged his wound simply and quickly, and then smashed the black-winged mantis to death, after all, with his strength, it was still possible to deal with a black-winged mantis that couldn't move.

Next, it's time to look for crystals.

Insects do not have a heart like humans, but along the midline of the back, there is a body called the dorsal blood vessels, which can be seen as a combination of the heart and blood vessels, similar to the major cardiac muscle, and the muscles that have the function of compressing and beating to transport blood are also here.

Tang Ling was bent on finding crystals, and it was impossible not to pay attention to such knowledge.

Without half a minute of delay, Tang Ling used the sharpest one in his hand to ask Auston to borrow a week's military thorn and began to simply dismantle the black-winged mantis.

When the exposed dorsal blood vessels showed the characteristics of toughening, Tang Ling's heartbeat accelerated.

He groped for these tenacities, looking for their central point, but the center point of his prayer had crystallized mutation.

At this time, Tang Ling's movements became extremely slow, and it was not until there was an unusual hard feeling in his hand that Tang Ling suddenly stopped, almost impatiently looking towards that hard place.

Very small, only half the size of a thumb.

The strange blood red color exudes a faint fluorescence, and the texture is very delicate and semi-transparent.

When I took it out, I could see a few very, very fine purple filaments in it in the sunlight.

Is this a crystallization? That's the crystallization of every gram worth 50 hope points? Holding almost three grams of crystals in his hand, Tang Ling had an unreal feeling, he quickly calculated that even if he didn't stop doing all the tasks he could complete in the past twenty days, he wouldn't be able to earn 80 hope points, and such a small thing was worth at least 150 hope points?

Tang Ling immediately tightened his fingers and held it tightly, it didn't feel like holding a stone at all.

Its warmth and delicacy are like life, which makes people love it from the bottom of their hearts and want to have it.

What luck!

You must know that even a Level 3 mutant beast may not definitely produce crystals, if it is the premise that the whole heart begins to harden, rather than part of it hardens first.

And I got it on a third-level mutant insect.

What's more, depending on the grade, this crystallization should at least reach the level of a good product.

It's just that now is not the time to indulge, even if this place is close to the edge, it is still on the battlefield, and accidents can happen at any time.

Moreover, this black-winged mantis is a high-value insect among the third-level mutant insects.

Its forelimbs and wings are all within the scope of the Hope Barrier Society's acquisition of Hope Points.

Its meat volume is definitely not much, and it also belongs to the scope of the Hope Barrier Society.

Obviously, I can't dispose of the corpse of the Blackwing Mantis here, and if I am unlucky enough to meet an accident, the injured myself will obviously not be able to maintain the best fighting condition.

What's more, there are no weak guys who appear on the battlefield.

After putting away the crystals, Tang Ling couldn't think of a better way, so he simply picked up the corpse of this praying mantis and quickly rushed towards the manglin.

The Black-winged Mantis weighed about 100 kilograms, but it had lost so much blood and was already weightless, coupled with Tang Ling's strength, this weight was nothing.

**

The place that Tang Ling considered to be a 'feeding ground' was obviously the best place to dispose of the corpse of the Blackwing Mantis.

And it's close to the battlefield.

The god of luck favored Tang Ling this time, running at full speed, coupled with taking the tactical backpack hidden in the tree, Tang Ling only took about five minutes to successfully run to the 'eating place'.

There is no risk along the way.

But dissection is a troublesome thing, there are a lot of hard places on the body of the black-winged mantis, fortunately there is Auston's treasure army thorn, otherwise Tang Ling doesn't know how much more time it will take to use his stainless steel dagger.

Even so, this praying mantis was also dismembered very roughly, but the small piece of hard armor on the important chest, the forelimbs that had been cleverly hollowed out, as well as the wings and a few legs, Tang Ling did not miss one.

Tang Ling tried his best to put it in the elastic tactical backpack, but the huge forelimbs and wings could only be hung on the hook of the backpack, which was also a helpless choice.

But fortunately, it was rare to meet people in the North Wing Forest, and Tang Ling didn't believe that he could still meet robbers.

As for the meat, after Tang Ling cleaned it, he roasted it all and ate it.

After the battle, it needs to be replenished, even if it exceeds the body's needs today, but with the feeding method taught by Su Yao, it can also be quickly digested and decomposed, and turned into energy and stored in the body.

Patting his stomach with satisfaction, Tang Ling felt the power of this third-level mutant insect meat, although dozens of kilograms of body were cleaned of the cracks, there was only less than five kilograms of flesh.

But these five kilograms of meat at least let him not fall into the trouble of hunger for two days, and he can also have time to do some tasks and accumulate some hope points.

The point is that the improvement of the body of this quality of meat is stronger than that of the king beast.

To become stronger, start by eating! Start by being able to eat.

Tang Ling was satisfied, with the harvest, endured the exhaustion, and decided to be in that place... His 'secret base', after hiding the harvest, will return to the Fortress of Hope.

A rich harvest may give him a chance to sleep for a few hours tonight.

However, the time on the road must not be wasted, and the gains and losses of this battle must be summarized as soon as possible!
