Xiang Yihang fought and retreated, the only thing he was grateful for was that the unknown advanced civilization was that this place was big enough.

After a painful battle, Xiang Yihang finally slaughtered more than 10,000 sandmen.

Fortunately, the distance between him and the sandman was far enough, and there was a faint true qi shield blocking it, otherwise he would definitely be splashed with the sandman's flesh and blood.

Xiang Yihang swallowed a Guiyuan Pill, and this battle with Shamin made him a little prostration.

But the sandfolk are just an appetizer, and the next big prehistoric animals to deal with are the main thing.

Although the sandman had been wiped out by him, he still kept retreating so as not to be caught up by those large animals, and he had to delay time to allow Guiyuan Dan to fully release his energy.

But the prehistoric animals didn't give him much time, because there was already a whistling sound in the air, and it was a large group of pterosaurs!

Xiang Yihang had no choice but to sacrifice the flying knife again, wanting to kill the front pterosaur in the shortest possible time.

The speed of the flying knife was very fast, and Xiang Yihang also controlled it very precisely, and each flying knife directly cut into the neck of the pterodactyl.

However, what happened next shocked Xiang Yihang's heart, because the head of the pterosaur was not cut off by his flying knife!

According to Xiang Yihang's previous experience, Daomang could directly cut off the neck of Shamin, and he thought that against these prehistoric animals, Daomang could also cut off their necks.

The place where the flying knife passed was indeed cut off, but the place where the knife swept was not cut, only a small part was cut, and the flesh and blood of those pterosaurs could resist the cutting of the knife.

Therefore, those pterosaurs, although half of their necks were cut off, did not lose their ability to move, and still flew towards Xiang Yihang quickly.

"It seems that the skin and flesh of these prehistoric animals are too thick and thick, and where the blade is not reached, it cannot be cut, and the role of the knife is too limited. Xiang Yihang thought to himself, fortunately, his weapon is a superb weapon, if it is an ordinary weapon, not to mention the sword, it is the blade, I am afraid it may not be cut off.

Xiang Yihang sacrificed the best flying sword, and magnified it to the extreme, he hoped that with a sword down, he could cut off a winged dragon head.

His idea was indeed good, and he did it, and with a single sword, he cut off the neck of a pterosaur, and the pterosaur fell to the ground.

However, Xiang Yihang felt that according to this style of play, his spiritual power would not last long.

Even if you keep eating Guiyuan Dan, you may not be able to catch up with the consumption rate.

The only thing he felt slightly relieved about was that the large, wingless prehistoric animals could not fly into the air, but could only attack underground.

This is most likely due to the fact that its physical body is too large, and if it flies in the air, it consumes too much energy, so an unknown civilization has set it to be unable to fly.

However, winged pterosaurs and other animals were reckless in the air attacking Xiang Yihang.

Moreover, these flying prehistoric animals are as fast as lightning, comparable to Xiang Yihang's speed.

Xiang Yihang realized that there was no better way than to deal with it head-on, and if he blindly escaped, he was afraid that he would die faster.

He brace his spirits and control the flying sword and knife to constantly attack the pterodactyl in the air.

A flying sword kills a pterodactyl with a single slash, while a throwing knife takes two times to hack a pterodactyl.

As a result, there were more and more pterosaurs, because Xiang Yihang's speed of killing pterosaurs was too slow.

What to do?

If this continues, once it is surrounded, it will be difficult to escape.

"Smack!" Xiang Yihang was swept away by the wings of a pterodactyl, and this wing slapped so hard that his blood surged upward, and he almost spit out a mouthful of blood.

Fortunately, as soon as the pterosaur slapped him away, he was swept away by inertia, and if he didn't come again, Professor Pan would definitely die.

Xiang Yihang quickly returned to the flying sword and concentrated on coping.

However, due to the delay of being filmed and flying for a little time, the density of pterosaurs around him increased again.

At this time, a super-large pterosaur that was five or six times larger than the other pterosaurs suddenly flew rapidly from behind the encirclement, opened its big mouth and bit directly at Xiang Yihang.

Because the speed was too fast, Xiang Yihang didn't have time to recall the flying sword to fight, and saw that the two of them spun around out of thin air, and then happened to land on the back of the large pterosaur.

Xiang Yihang was no longer polite, and plunged the flying sword into the back of the pterosaur, leaving only part for Professor Pan to stand on, while he stepped on the pterodactyl's neck.

The pterosaur was in pain, accelerated wildly, and directly crashed into the pinchosaur that came at extreme speed on the opposite side, instantly knocking over those pterosaurs that were smaller than it and falling down.

"This is a good way, let you go crazy again!" Xiang Yihang picked up the flying sword in his hand and kept stabbing the neck of the pterosaur at his feet, the pterosaur became more and more angry, and took Xiang Yihang on a rampage, and the pterosaurs that were hit by it fell down one after another.

In this way, Xiang Yihang drove this large pterosaur and rampage in the pterodactyl encirclement, and the pterodactyls that were hit fell to the ground one after another, and Xiang Yihang also saved a lot of effort.

All he needed to do now was to keep provoking the large pterosaur beneath his feet and causing it to crash into more pterosaurs.

Soon, however, Xiang Yihang couldn't laugh anymore because a larger pterosaur was speeding towards him.

If he collided with the pterosaur under his feet, with the speed of these two pterosaurs, they would inevitably lose both, and he and Professor Pan would definitely be knocked into the air or even killed.

But the bad things didn't stop there, Xiang Yihang found that as the large pterosaur on the opposite side flew towards him, the pterosaurs outside the encirclement also rushed towards him.

He became the center point of these pterosaur impacts!

If it is loaded, these pterodactyls swarming from all directions will inevitably knock him and Professor Pan into pulp!

"Are you really going to die?" Xiang Yihang muttered to himself.

Professor Pan, on the other hand, was already numb at this time.

said that the time was slow, but in fact, the situation that Xiang Yihang faced was only in an instant.

The speed of those pterosaurs was faster than that of civil aircraft, and in the blink of an eye, they were roaring from a few kilometers away!

However, Xiang Yihang had not thought of a way to escape, because the encirclement of the pterosaurs had been formed, and no matter which direction they fled, they would be continuously hit by a large number of pterosaurs.

When the pterosaur under his feet was killed, he and Professor Pan would be killed as well.

There is no time to delay, it has come to the time of life and death, but Xiang Yihang still can't think of a way!

Life and death are in an instant!

"Tianhuo, if you don't want to die, come out immediately!" Xiang Yihang shouted helplessly, but he didn't expect Tianhuo to save him.

After all, the heavenly fire is just a kind of fire, although it has the function of devouring souls, but these cloned prehistoric animals seem to be just loaded with chips and act according to instructions, these prehistoric animals are not actually living things, but dead things.

Their energy source is not food, but energy crystals implanted in the body.

Since the heavenly fire cannot devour the souls of prehistoric animals, there is only one way to burn them.

But so many prehistoric animals, with the small body of Tianhuo, will definitely not be able to burn out, so in the end there is still a way of thinking.

However, Tianhuo was his last straw after all, so at the last moment, whether it worked or not, he could only call for help from Tianhuo.

"What are you shouting, I've been paying attention to it!" Tianhuo's voice came, and its calm appearance made Xiang Yihang hear the most beautiful fairy sound!

The heavenly fire was floating above Xiang Yihang's head at this time, its flame had expanded a lot, its flame was similar to the flame of a lighter, and now, it was the size of a rice bowl.

The moment the heavenly fire appeared, the high temperature immediately spread to all directions, and the fast-moving pterosaur couldn't help but pause, but immediately continued to impact.

"Even if you burn them, with their inertia, the two of us will still have to die!" Xiang Yihang shouted.

"What the hell are you yelling at, just look at it!" Tianhuo said angrily, but it didn't stop moving.

As the Heavenly Fire Divine Nian spoke, it seemed that a lot of silk threads were emanating from its body, and then a miracle appeared!

I saw that those pterosaurs that were rushing towards them suddenly became chaotic, and I didn't know what they were stimulated, so they turned around one after another and crashed into the other pterosaurs next to them.

In this way, those pterosaurs who were originally besieging Xiang Yihang suddenly fought on their own, and in a moment, the pterosaurs around Xiang Yihang fell to the ground, and only a few hovered in the distance and did not dare to approach.

"How did you do it!" Xiang Yihang was stunned for a moment and asked.
