The flat terrain on the banks of the river, without complicated jungles, makes it very convenient for the dragons to walk, and the temperature during the day is very high, sometimes exceeding 40 degrees, so the dragons travel at night, and recently they start to rest in the afternoon and set off at night.

Every time he marches, Zhang Jun will divide the team into three roads, each road before, in the middle and back, there will be about three big dinosaurs in charge, the small dragon is sandwiched between the big dinosaurs, the three-way team maintains a close distance of dozens of meters, once there is a threat, he will summon all the small dragons to the center, and then let the big dinosaurs deploy to form a phalanx, which can deal with threats from all directions.

Of course, there are many dinosaurs who do not understand Zhang Jun's intentions, the phalanx will often be deformed and loose by them, which is also inevitable, every time Zhang Jun must personally supervise them everywhere, try to maintain the formation of the phalanx, but once there is a fight, the formation is difficult to maintain, there are many small dragons will rush out of the formation by themselves, run to the dangerous area, at this time no one can save them, they have to be left to fend for themselves, after all, their wisdom is too limited.

Three dinosaurs marched along the river bank in a long line, there were many insects in the jungle at night, all kinds of insects crawling among the weeds, there were insect chirping everywhere, there were also several flying insects flying around in the air, and the sound of Allosaurus flicking its tail to drive away flying insects could often be heard.

The dragons also had a way of dealing with flying insects, and they sprinkled some dirt on their bodies by the river during the day, so as to prevent the bite of bloodsucking insects that rely on their smell to find their feeding targets.

All the way to the west, the dragon group did not encounter much threat, occasionally a few Void Bone Dragons and Sabertooth Dragons came to attack, but they were all blocked by the mighty momentum of the dragon group, after easily killing a few bewildering dragons, the dragon group arrived at the area where the mountain peak was located after ten days.

The peak is also on the south bank of the river, about five kilometers away from the river bank, Zhang Jun arrived in front of him, only to see clearly that it was a dead mountain, that is, there was no sign of animal and plant activity on the mountain, it seemed to be covered with gray-black soil layer, the top of the mountain was conical, and the area was not large, which made him immediately think of a volcano.

This is the second time Zhang Jun has seen a volcano, he has seen a volcano group with several vents, but it is several extinct volcanoes, and there is no sign of activity for a long time.

The volcano also seems to be very quiet, at least there is still lush vegetation cover within a few kilometers of it, so it can be concluded that it has not erupted recently, Zhang Jun also relieved himself and continued to move forward, and the giant beast he heard the sound before was nowhere to be seen, maybe it has not been active in this area recently.

It is only about 200 kilometers away, Zhang Jun can reach the area of the prehistoric spaceship crash, originally after the spacecraft crash, this area around a few hundred kilometers, turned into a dead area, but after hundreds of millions of years, the soil here has been purified, the water source has been restored, the poisonous gas in the air has gradually dissipated, and the animals and plants have returned to the prehistoric prosperity again.

The river meandered and twisted into the depths of the mountain, the river in front of it became a little narrow, the river became turbulent, Zhang Jun could hear the roar of the river in the distance, some high cliffs and steep rocks on both sides began to increase, and some emerald green ancient pines growing on the high cliffs stood proudly.

This landscape reminds Zhang Jun of the Three Gorges of the Yangtze River, which is also home to a narrow canyon where the river is also fast and fierce, and such an area is not conducive to dinosaurs going down the river to drink, so it must be crossed as soon as possible.

After walking a few kilometers, the dragons arrived at the area where the cliffs were lined with high cliffs on both sides, and they walked close to the edge of the cliffs, and saw two high cliffs a few hundred meters in front of them, about fifty meters above the surrounding ground, symmetrically distributed on both sides.

The two cliffs are so steep and more than a few hundred feet wide that they cut off the communication between the jungle and the river, and most of the animals cannot get close to the riverbank, and the animals that live here have to make a detour of more than five kilometers to find a suitable place to drink.

When the huge gray-brown cliff was exposed in Zhang Jun's eyes, he immediately saw an amazing scene, because under that high cliff, there was a sparse jungle, about a few hundred zhang wide, there were no tall trees, only low ferns and wild grasses that were faintly distributed, and the field of vision was very wide.

Zhang Jun was not surprised by its topography, but he saw that there were more than a hundred various animals moving under the high cliff in front of him, and the black pressure flashed one by one.

"Beautiful dragon, stegosaurus, bewildered dragon, diplodocus, Augustinian, Chaoyang dragon, hedgehog dragon, earthquake dragon, ankylosaurus, virtual bone dragon, ......" Zhang Jun saw that among the dragons, there were many familiar figures in it, including many herbivorous and carnivorous dinosaurs that he had seen before, and several herbivorous dinosaurs that he had not seen before.

This is the first time Zhang Jun has seen so many varieties of dinosaurs gathered together, they are not gnawing on the weeds on the grass, but all facing in one direction, looking up at somewhere, from Zhang Jun's direction, you can't see what they are looking at.

"Roar!" Several loud roars suddenly came from the grass under the high cliff, and Zhang Jun looked up and saw that several dinosaurs had broken out in conflict on the grass.

They fought near the bottom of the cliff, it was not a carnivorous dinosaur, but a group of stegosaurus and a hill-like seismosaurus exchanged fire, the body length of the stegosaurus was less than eight meters, the body length of the seismosaurus was more than thirty meters, and there were more than twenty stegosaurus, relying on the dragons to crowd up, blocking the seismosaurus in the middle, and let out a roar.

Zhang Jun didn't understand why several herbivorous dinosaurs had a dispute, there were lush branches and weeds all over here, there should be no shortage of food, I don't know what caused this fight.

Stegosaurus and Seismosaurus were both herbivorous dinosaurs, they were four-legged walking animals, without claws and without fangs, and the confrontation between them depended entirely on strength and defense, in contrast, Stegosaurus had stronger dorsal spines and Seismosaurus had thicker skin and great strength.

The stegosaurus surrounded the earthquake dragon and began to roar around the earthquake dragon, and the other dinosaurs kept a certain distance from them, and the virtual bone dragon, as a carnivore, had no advantage in front of these big guys, and also retreated to the side to watch the battle.

Soon, only the dust in front of them was raised into the air, and the huge vibration emitted by the earthquake dragon made all the dinosaurs feel terrified, and they tried to maintain their center of gravity so as not to accidentally fall, once they fell, they probably couldn't get up, maybe before they could get up, they would be trampled to death by other animals.

"Roar!" Although the earthquake dragon was weak, but with its tall body, it began to gradually rage, it suddenly threw its long tail towards a stegosaurus close to it, and after a bang, the dorsal spines on the stegosaurus were broken in a row, and after moving a few steps sideways, it lost its center of gravity and fell heavily to the ground, blood immediately spilled from its mouth and nose, and it lay on the ground screaming.
