Zhang Jun made a preliminary judgment, the depth of this puddle is more than ten meters, and his body length is more than ten meters, if he goes down to take out the glowing object, it should not be a big problem, he weighed the pros and cons, and decided to go into the water to give it a try.

Then Zhang Jun poked his paws into the water, to feel the water waves at the bottom of the water trembling, if there is a large creature in the water, it will definitely stir up a large water wave, he tried for a few minutes, found no threat, so he began to carefully jump into the water.

After a huge wave of water rippled out, Zhang Jun's body sank into the puddle, he began to aim his head at the bottom of the water, and his limbs began to paddle to get himself close to the bottom of the water, his body was huge, and the water depth of ten or twenty meters was not difficult for him, and he soon approached the bottom of the water.

Zhang Jun opened his eyes and saw the glowing object lying quietly in the mud under the water, only partially exposed, and immediately stretched out his claws to grab it out, and then found that it was just a strange square block, only about two inches long and wide, emitting a soft white light, it was not a five-pointed star leaf, and it could not be seen clearly in the water, so he wanted to surface and study it again.

Zhang Jun saw that there was indeed a dark river under the water, and there was a passage about fifty meters wide in it, and he didn't know where it led, so he didn't dare to explore inside, so he began to turn around and prepare to return to the water.

At this time, Zhang Jun's keen sense of touch felt that there was a sudden tremor in the dark river, as if some creature was approaching, he was not familiar with the surname of water, so no matter what the other party was, he had to return to the water.

Zhang Jun quickly turned around and paddled towards the water, and soon gradually surfaced, but the trembling at the bottom of the water became more and more violent, the creature seemed to have entered the puddle and began to float, at this time Zhang Jun was already lying on the edge of the puddle and climbed up hard.

As soon as Zhang Jun climbed up, he immediately jumped a step forward, because the creature behind him had already caught up, and then a huge splash burst out of the puddle, and a big guy suddenly rushed out of the puddle.

It was a yellow-skinned creature with four limbs, with a slender body, a body as thick as a cow, like a crocodile's streamlined shape, but not a crocodile, no crocodile-like armor on its back, and five claws on its limbs, very much in line with the characteristics of the killer last night.

The guy chased Zhang Jun's ass and bit it, most of his entire body was already exposed to the water, only the long tail was still in the water, Zhang Jun turned around, and after a closer look, it turned out to be a plesiosaur.

Plesiosaur is a marine reptilian, like ichthyosaurs, belonging to the amphibians, it is a monster that evolved after the terrestrial dinosaurs entered the ocean, the limbs became very short, almost turned into fins, some plesiosaurs' claws have disappeared, but this plesiosaur still retains its claws, the head is similar to the dinosaur, it can easily climb to the land, and move flexibly.

This plesiosaur is more than twenty meters long, almost close to thirty meters, it is a well-deserved giant, its head is two or three times that of Zhang Jun, its sharp teeth look very hideous and terrifying, and the blue eyes the size of a soup bowl are staring at Zhang Jun viciously.

Zhang Jun carefully put the square on the ground on the side, and then carefully looked at the plesiosaur that had not yet evolved a fin, compared the fit between its claws and the paw prints on the ground, and found that the wet marks left on the ground were consistent with the paw prints he saw, the size and length, and the gap between the claws were very consistent, and he immediately concluded that it was the monster that killed the evil dragon last night.

This plesiosaur was too large, estimated to weigh more than ten tons, and it was not an easy guy to deal with, and it had already climbed up, forcing Zhang Jun to retreat, and let out a few low roars from its mouth.

And after this plesiosaur forced Zhang Jun back for dozens of meters, he found that there were several Allosaurus in other directions, and these Allosaurus then surrounded him from behind the plesiosaur's ass.

The plesiosaurus turned its head and began to look around at the eight Allosaurus, although there were many Allosaurus, it relied on its huge size, and it didn't seem to take the dragons too seriously, and then turned its head and glared at Zhang Jun, the intruder, and opened its bloody mouth, ready to attack.

When the guy approached, Zhang Jun found some small paw prints on his body, although it did not break its thick skin, but left some marks, which looked like paw prints left during the fight with the evil dragon, which further confirmed the conclusion that the plesiosaur was the murderer.

This plesiosaur ate the leader of the evil dragon, and also ate the five-pointed star leaves together, and Zhang Jun only needs to kill it to get the leaves. Although this guy's size looks terrifying, in fact, Zhang Jun also faced a giant python last time, when he and the giant python fought alone, it was indeed incomparable, but now it has seven helpers, and the situation is different.

At this time, the giant turtle had already taken the opportunity to crawl into the lake, and the Allosaurus had already launched its usual encirclement attack formation, surrounding the legion-ridden plesiosaur in the center.

Zhang Jun deliberately retreated a long distance because it wanted to keep the plesiosaur away from the puddle, and if it was allowed to enter the water, no matter how many Allosaurus there were, it would not be able to defeat it.

Zhang Jun retreated while observing the terrain inside the cave, except for a few boulders, there was no terrain to rely on, and there were no stones of the right size to use, so he had to fight hard to solve this difficult guy.

Fortunately, this plesiosaur is an animal mixed in the ocean, its claws are not as sharp and slender as those of land animals, but its teeth are as good as those of terrestrial animals, and the longest front teeth are more than a foot long, nearly twice as long as Zhang Jun.

However, on land, this guy's flexible surname has been greatly affected, the degradation of its limbs makes it no longer able to stand upright on all fours, and its head cannot be raised to a certain height, at most it can only be raised up to two meters high, which is a big disadvantage, and the mouth of the Allosaurus can be raised to a height of five or six meters, and it can condescendingly attack the plesiosaur.

The plesiosaur encountered a small number of evil dragons and could easily bite their necks, but the lethal parts of the Allosaurus were out of its reach, and it didn't seem to realize it, because it had never been in this cave, and it had encountered so many tall dinosaurs at the same time, and it soon discovered that these dinosaurs were not herbivorous dinosaurs, and when they opened their mouths, their mouths were full of sharp teeth that proved their carnivorous dinosaurs.

"Roar!" After retreating to the right position, Zhang Jun immediately opened his big mouth and roared, showing his mouth full of sharp weapons to the plesiosaur, and then the plesiosaur saw clearly that Zhang Jun was not a soft persimmon that could be bullied at will, and seemed to regret chasing it out, but he was not very afraid.
