He Jun manipulated for a while, and the unchanged monotonous scenery made him a little impatient, so he gave the drone a cruise command and no longer controlled the drone manually.

The flight of the drone was not affected in any way, and it flew meticulously along the established route in accordance with the established procedures.

He Jun switched the display mode of the screen to red mode, and the originally green screen instantly turned into a red world with uncertain light and dark.

At this time, it was about 10 o'clock in the morning, and the temperature outside was about 30 degrees, but the temperature of the trees was lower than the ambient temperature, and the body temperature of the large dinosaurs inhabiting the forest was slightly higher.

He Jun touched his chin thoughtfully, it seems that the dinosaur is really a homeothermic animal, but unfortunately he can't catch one and test it well!

For a long time, the scientific community has several different views on the body temperature of dinosaurs, one view is that dinosaurs, like their close relatives crocodiles, are ectotherms that are greatly affected by the ambient temperature, and only in this way can their food consumption maintain the metabolism of their huge bodies, otherwise, dinosaurs must keep eating all the time to avoid starvation......

Crocodiles and snakes can go without food for a month after eating a meal, which is the best proof of this.

Another view is that dinosaurs, like mammals, were homeotherms with a constant body temperature, otherwise the speed of dinosaurs would have been fatally affected.

This perception is also well-founded – reptiles move slowly at low temperatures, and only when temperatures rise do they move flexibly and frequently.

There is also a statement that combines the merits of the first two views. Dinosaurs are thought to be ectotherms that can control their body temperature, so dinosaurs don't need to eat a lot. It can also maintain enough vitality.

He Jun always felt that the third view was very, but when he saw the bright red dinosaur outline on the screen. He prefers the notion that dinosaurs were homeotherms.

If dinosaurs were ectotherms, how could giants ride them to fight?

However, these three inferences are based on the study of modern animals, and they seem to be well-founded, but in fact they are all empty buildings.

About seven or eight minutes later, Bi Min suddenly said on the radio: "Hey, brothers, look what I found!" He shared the settings of the footage he received, and the others immediately received the real-time footage.

He Jun tapped a tap on the screen, and the red picture immediately returned to normal.

The dense forest is not visible on the screen. Instead, there was a verdant grassland, where several tyrannosaurus rexes with knights were running wildly, chasing panicked prey.

The dragon knight on the back of the tyrannosaurus was armed with a short spear, and one of them suddenly threw a short spear, and the short spear lightningly struck a fleeing dinosaur

The camera zooms in, and a forest of animal skin tents in the depths of the grassland comes into everyone's eyes, and in the camp, teams of giants wearing full-body armor can be seen everywhere.

He Jun's heart trembled: "The giant's barracks? Brother Min, distance. What is the distance? ”

Bi Min glanced at the screen: "Seventeen kilometers to the north, straight-line distance." ”

"Tell me, are they here to trouble us?" Zhou Yang said uneasily.

"Not really." Bi Min said, "Seventeen kilometers away from us." ”

"They have cavalry!" Zhou Yang reminded.

"What's wrong with the cavalry?" Ma Ning blew his beard and glared. "Cavalry is useful only on the plains, these seventeen kilometers are forests! Do you understand the forest? ”

I have only heard that the northern steppe is rich in cavalry, but I have not heard of the cavalry of the southwest jungle. The only class suitable for fighting in this environment is the mountain infantry. And not expensive heavy cavalry.

"Of course I do, but what about those dragoons yesterday?" Zhou Yang reminded again. "The cavalry you're talking about are riding horses, and these people are riding tyrannosaurs. Can it be the same? ”

Ma Ning was stunned for a moment, and rarely agreed: "It makes sense, the giant's matter is really uncertain." ”

Although he said this, he still believed in his heart that the community was not the goal of these giants.

The point is that the giant's camp is too far away from the community, the environment in the jungle is changeable, seventeen kilometers in a straight line, it is not strange to walk around thirty or fifty kilometers, if the giant wants to retaliate, there is no reason to place the camp so far.

Zhou Yang counted the heads in the camera: "There are almost one hundred and eighty giants I can see, and there must be some people in the tent who have not shown up, can we stop so many giants?" ”

"If you can't stop it, you have to stop it." He Jun gritted his teeth and said, "You can't leave even if you die." ”

"Hey, I've found something here, look!" Zhou Yang shouted to share the signal.

He Jun chose to receive it, and the picture lit up, and in the midst of a lush forest, a small lake with a considerable area appeared, and between the lake and the forest was a spacious sandy area, on which seven or eight animal skin tents were erected.

The shape of these tents was similar to the ones I had just seen, except that there were no giants or tyrannosaurus rexes nearby.

Probably because of the relative proximity, the details of the tent can be seen very clearly. He Jun felt that these tents were likely to be sewn from dragon skin...... The legendary cowhide tent is very remarkable, and the dragon skin tent is so tall and tall that there is wood?

He Jun can't wait to grab a gun and a shoulder cannon now, and rush over to grab one back!

This is a prehistoric antique from 100 million years ago, a good thing that the state doesn't allow to be bought and sold at all, a good thing that can't be found with a lantern, and a good thing that can't be found in this shop after this village!

Fortunately, he was impulsive, but he did not lose his mind and forcibly suppressed his greedy mind.

"How far is this place?" Ma Ning asked.

"It's just over six kilometers, less than seven kilometers." Zhou Yang replied.

"So close?" He Jun's brows furrowed, and he woke up from the dream of the treasure, "This place may be the camp of those dragon knights yesterday. ”

"Anyway, I don't understand, what do they mean by putting such a few people here?" Ma Ning raised his voice.

"What do you mean it has to do with us?" Bi Min pursed his lips disdainfully, "Is it not necessarily the tent of those people yesterday." ”

"Brother Min is right, let's look around first." He Jun suggested.

"Good!" Zhou Yang happily agreed, and set the drone to patrol and reconnoiter with the tent as the center.

Without waiting for Zhou Yang to find out again, Ma Ning suddenly said in an extremely serious tone: "Brothers, look at what I found!" ”

He Jun switches the screen for the third time.

The drone's camera is directed at a clearing overgrown with fern weeds below, and groups of small dinosaurs are jumping around in the grass, breaking into piles to feast.

The food they nished was actually more than two dozen mutilated giant corpses! (To be continued......)

PS: Today's state is still not good, I'm going crazy.
