Originally, the Allosaurus group had been running at the front, and the oak dragon and the horned nose dragon did not dare to steal the limelight from the dragon group, because the dragon group would not hesitate to eat them as a snack when they were hungry, so they deliberately held them behind this time and did not continue to advance.

Zhang Jun ordered the dragons to stop advancing, because he was looking for where to enter the seemingly closed hill in front of him, so he began to lead the dragons around the hill from the right side, and then the group of oak dragons also arrived in this area, they were also blocked by the hills, so they followed the allosaurus group around again.

After looking for about ten minutes, Zhang Jun saw an entrance, which was only a few meters wide and could only accommodate a large dinosaur, and the entrance was at a height of about 50 meters above the ground, leading from a very long slope to the bottom, which could be climbed up from the slope. The entrance looks like a notch, and from a distance, it looks like a notch left in a porcelain bowl.

Zhang Jun was about to lead the dragon group to climb up the slope, and when he walked up the slope for a few meters, he suddenly felt a violent tremor under his feet, as if the ground had been hit by something, and he suddenly felt that something was wrong.

A few seconds after the tremor appeared, Zhang Jun found that in the gap in front of him, a pillar of light that looked like smoke and dust shot out at some point, as if a strong belt of smoke and dust appeared inside.

Zhang Jun immediately made a decision, he faintly felt that something was wrong, and immediately retreated down the slope with the dragons, and then gave way to the oak dragon and stood a hundred meters away on the side of the slope.

Seeing that Zhang Jun's group of dragons had moved away, the group of oak dragons followed from behind and walked directly up the slope, which was high enough for them to resist the invasion of the magma torrent, so this was exactly what they had been waiting for.

There are more than thirty oak dragons, each of them looks light, the steps are light and powerful, and they jumped up and walked up, their body length is only about three meters, several stand together, and they can also enter the entrance side by side, and Zhang Jun has heard a strange sound near the entrance below, as if the wind is whistling, so he is even more afraid to approach the past.

When the group of oak dragons approached the entrance, several oak dragons rushed up and stood at the entrance, and the top of the column of smoke that Zhang Jun saw just now suddenly appeared near the gap.

The dinosaurs below may not have seen it, but the dinosaurs above could see it very clearly, and three oak dragons let out a few roars almost at the same time, and then began to turn and retreat, but their bodies then suddenly flew up and rolled down as if they had been thrown by some great force.

Then Zhang Jun saw the pillar of smoke that he had seen just now, and suddenly appeared from the entrance, the pillar of smoke was rotating rapidly, mixed with the sound of whistling wind, about 20 meters in diameter, and the entrance was suddenly filled with green smoke, flying sand and stones.

"Hurricanes?" Zhang Jun was very surprised, he didn't know how this kind of area produced tornadoes, and immediately ordered the dragons to continue to retreat to one side.

Then I saw the tornado of smoke rushing through the entrance, rushing straight out, throwing the oak dragon into the air, a wild sand, gravel, grass clippings flying everywhere, a mess.

The oak dragon group jumped up and down the slope and retreated wildly, with a frightened cry from its mouth, an oak dragon jumped to a height of several meters, and was suddenly caught up by a hurricane, and directly swept it in, a few seconds later, I saw that the oak dragon's body was suddenly thrown out from a certain angle, flew out directly for dozens of meters, fell to the ground, fell to pieces, lay on the ground and screamed twice and then stopped moving.

Then a hurricane that connected to the sky swept down the slope and into the jungle, knocking down rows of trees, uprooting others, and then dissipating the energy for kilometers away.

Seeing the group of oak dragons being swept away, Zhang Jun was glad that he was cautious, he observed, the oak dragon was swept into more than ten by the hurricane, there were more than a dozen oak dragons lying on the ground, and some were moving, a few struggled to get up, and a few were already dead.

"A big meal picked up for nothing, don't eat it for nothing." Zhang Jun immediately beckoned the dragons to run over, they had been running for so long, it was time to stop and have a full meal.

The remaining oak dragons were at a loss, they were a little afraid of the entrance, but the more than a hundred Allosaurus here were also crazy, which made them very frightened, and finally under the leadership of an oak dragon, about twenty oak dragons rushed up the slope again, this time they did not meet resistance, but all rushed to the entrance.

Zhang Jun was not in a hurry to climb up, the ceratosaurus in the distance had stopped walking, they did not dare to approach, expecting to wait for the Allosaurus to eat enough, and there would be some minced meat left for them to satisfy their hunger, but obviously the meat of the dozen or so oak dragons was not enough to eat, and they were soon gnawed by the Allosaurus until only bone residue remained.

Then Zhang Jun cautiously climbed the slope with the dragons, and at the entrance, he stood near the entrance with Qili and Bald Head and looked inside, carefully distinguishing whether there was any danger.

Inside is a huge meadow, the meadow looks relatively flat, this hill is indeed a huge circle enclosed, the valley inside the hill is very huge, it can be said to be a small world, but there is only a single wild grass, there are no big trees.

The twenty or so oak dragons that entered in front of them actually began to leisurely gnaw on the grass and began to eat wildgrass leisurely, maybe they were too tired, consumed too much energy, and really needed to replenish them, so they didn't care about the allosaurus behind them looking at them, and only cared about eating frantically a few hundred meters away.

Zhang Jun looked into the distance, and saw that there was a dirt slope in the middle of the valley, like a yurt, but it was several times larger than the yurt, and the rest of the place was flat.

The entrance can directly enter the flat grass, Zhang Jun is not in a hurry, he is worried that the height of the magma can break through this entrance, so he ordered the dragon group to stop, and then he himself took the bald head and Qili, from a slope on the left side, began to pass through several large trees, and climbed to the top of the hill.

There was vegetation cover, so there was no need to worry about landslides, and Zhang Jun and Lianglong soon reached the top of the hill and began to look around the surrounding landscape.

In the distance, the drooling horn-nosed dragons were still watching, they didn't dare to approach, and farther away, there were many large dinosaurs that began to emerge, and the dragon's heads were moving, there were more than a thousand of them, and they could get close in about half an hour.

The grass inside is closed, and if those thousands of brute beasts run inside, then this valley will definitely become extremely chaotic, and it will be dangerous for so many little dragons to be inside.

So Zhang Jun thought about it carefully and decided to take Xiaolong to the top of the hill to settle down, and not enter the grass for the time being, and wait for those big guys to come in, and then see the situation.
