The two subconsciously took half a step back before looking at Song Zheng with curious eyes. I guess the president may be performing some kind of ritual.

They did not dare to disturb, so they just stood and waited, and after a while, they heard a buzzing sound from under the cliff, like the sound of flies or bees flapping their wings.

As the sound grew louder and the movement became more pronounced, both men became nervous.

They didn't know what it was or whether it was harmful, so they could only tense their nerves and be ready to fight at any time.

Looking at the president again, Song Zheng still maintains that hugging posture and has not changed in any way. I had to be silent again.

However, as soon as their eyes left Song Zheng, Song Zheng opened his eyes, put his hands down, and said, "Okay, it's finally out." ”

"What's coming out?" the two of them hurriedly asked.

Song Zheng pointed forward: "See for yourself." ”

Airplanes!

A large canopy of unknown things poured up from under the cliff with a loud deafening buzzing sound, and at the same time a dozen torches were lit up at the same time, allowing them to see what was flying and what was happening on the other side.

Flying are bugs, lots of bugs, endless bugs.

They are slender insects with two pairs of wings, laughing like a sparrow, but longer than a sparrow, with a round head that does not see where the eyes are or where the mouth is, and no tentacles, if it describes their appearance, it is a large match with wings.

These flying insects gathered together in a dense fog as if they were scattered between the opposite cliffs. But they never fly to the cliffs on either side, as if there is a transparent protective shield on the edge of the cliff, so that they will never dare to cross the line.

It was also clearly visible from the opposite cliff because the torches were lit on the opposite side, where an altar was arranged, and in the center of the altar was a huge skull. The color of the skull has changed to black-brown, and it is not clear what kind of creature it is, except that it is definitely not a human skull.

Just by looking at it, Song Zheng's eyes shot a fine light. Secretly said in his heart, sure enough, it was correct as he guessed, and there were obvious traces of soul fire in that skull.

As he reacted, the sound from the iron pot also appeared in time. Let him be sure once again that there is really a particularly high-grade general ingredient there, from the soul fire of the abyssal black dragon!

The only question is how to cross the abyss between the two cliffs.

This abyss is a thousand meters long, even if Song Zheng borrowed the chain of spiritual power and swayed like Tarzan of the apes, it would never be able to swing over.

What's more, those flying insects in the cliff are not good men and women, don't look at them like matchsticks that burn themselves to illuminate others, in fact, they are all parasites in the abyss, powerful characters who can live on the body of the black dragon, if they really dare to swing over, it is estimated that even the bone frame will be eaten up in less than a second.

"President, do you want that skull, how do we get there?" Zhou Pan asked bluntly, still interested in the skull, "The owner of that skull must be very remarkable, such a big head, it seems to have horns, it can't be the legendary unicorn or dragon." ”

Song Zheng didn't expect that Zhou Pan would be able to guess it, and after being stunned, he smiled: "Your image thinking is good, that bone is the abyss black dragon, if you want to say that it is a dragon, it is not impossible." ”

"Damn, it's really fake, it's really a dragon!" Zhou Pan didn't expect him to just guess casually, but he even guessed correctly, and immediately became more interested.

"How do you get there, I really want to see the dragon's skull!" the little fat man was very anxious.

Song Zheng looked at Bai Xin.

Bai Xin held his head high: "President, what should I do?"

"Do you see those flying insects? You use net bombs and sticky sticky bombs, try to get them together and make a bridge out of them!"

As soon as Song Zheng said this, Zhou Pan and Bai Xin hurriedly swallowed a few mouthfuls of saliva and looked at Song Zheng with incredible eyes, which means that your brain hole is too big.

Song Zheng also saw their surprise, so he had to explain: "I can only think of such a way, don't worry about the number of flying insects is not enough, they are almost endless, and their body strength is definitely stronger than cement." ”

After such a wave of explanations, Bai Xin finally nodded suspiciously: "I'll try it." ”

He really didn't have much confidence, so he naturally didn't dare to make a guarantee.

Song Zheng rutted around the side, making room for Bai Xin, letting him wave casually and restart his brain.

Bai Xin stood on the edge of the cliff and thought for a while, and slowly raised the magic stone rifle.

Smack!

Two bullets in a company, one net bomb and one sticky sticky bomb.

Phew!

Two bullets exploded, but the sticky bomb exploded first. The slime spilled out, and many flying insects immediately stuck to it, and after the net exploded, it immediately wrapped the sticky flying insects inside. All at once, something like a sandbag was made.

Zhou Pan and Song Zheng almost cheered, they didn't expect it to go so smoothly!

But their happiness only lasted a second.

The sandbag-like thing fell into the cliff.

Song Zheng hurriedly said: "It's okay, go on, remember to stick to the cliff itself." ”

The failure just now can't be said to be a failure, it's just an oversight, Bai Xin forgot to stick the worm to the cliff first.

With that lesson in mind, the rest is much simpler.

Bullets are constantly being fired, and more and more flying insects are caught and glued together. and clinging to the cliff.

In a short time, a half-section bridge more than two meters long and one meter and five meters wide stretched out beyond their cliffs. It was all flying insects stuck together, and it was wrapped in a net, and Song Zheng even deliberately went up and jumped, and now the effect is very good, very strong, and he is immediately more happy.

However, only two meters of the bridge is obviously not enough, after all, the cliff is close to a kilometer, and two meters can only be a beginning.

And just relying on the viscous force of viscoelastic, it is still unknown whether it can support a kilometer bridge.

But as Bai Xin kept shooting, Song Zheng seemed to be a little worried.

Bai Xin actually has his own understanding of the structure of the bridge, and the adhesion of the flying insects is not simple and rude, but uses the wings of the flying insects to stick the flying insects by opening their wings, and the wings are superimposed and opened as much as possible to form buoyancy between the insect clusters, and at the same time, the insect clusters are spliced into hexahedrons and combined with each other.

In addition, the triangle is stable, so that the bridge made by flying insects is not only greatly reduced, but also the strength is not affected!
