Chapter 21 Love and hate, co-evolution! (Please collect and recommend)
This little Tyrannosaurus Rex was none other than Chu Xu, who had been secretly observing.

He also discovered that although the Triceratops' defensive formation was powerful enough to withstand a frontal attack from an adult Tyrannosaurus Rex, it also had a fatal weakness.

That means the rear is completely undefended.

Originally, Chu Xu had no intention of getting involved in this mess, but he was just in the direction behind the empty Triceratops group.

Because the father dragon was in front and attracted the attention of all the adult Triceratops, the few young Triceratops in the back were completely exposed to him.

Opportunities are rare and will never come back. In order to repay the kindness of Long Dad who occasionally sent him food in the past, Chu Xu decided to risk his life to accompany the gentleman.

Chu Xu chose a young Triceratops that was less than 1 meter long. Its neck shield shattered under his sharp teeth and fierce bite, and it was vulnerable. The neck below was also bitten through by Chu Xu effortlessly, killing it on the spot.

"Moo!!"

It was not until the adult Triceratops who were trying to resist the father dragon in the front heard the wailing of the baby Triceratops before its death that they reacted.

They never expected that the enemy would use such a tactic of feinting to the east and attacking in the west, with the adult Tyrannosaurus Rex attracting their attention in front, and then a little Tyrannosaurus Rex sneaking up from behind to attack them. It was so unethical!

Little did he know that when seeing this scene, Long's father was also confused. At first glance, he didn't recognize the huge change of Chu Xu at all. Then he smelled the familiar smell on Chu Xu, and then he reacted.

"Moo~~"

The female Triceratops that had been bitten by the dragon father let out an angry moo.
She was the mother of the young Triceratops. After seeing her child die tragically at the mouth of Chu Xu, she turned around and rushed towards Chu Xu without caring about the integrity of the defensive formation!

The two thick, long and sharp horns on the top of the female Triceratops emit a deadly cold light. If you are hit by them accidentally, the consequences will be disastrous.

In fact, generally speaking, Triceratops did not charge around with its huge horns like the rhinos of later generations. Their skulls and horns could not withstand such violent impacts, and they would often kill a thousand enemies but lose eight hundred of their own.

However, at this time, the female Triceratops, immersed in the grief of losing her child, had lost her mind. Her huge body seemed like an out-of-control truck, crushing towards Chu Xu.

In response, Chu Xu staged a Cretaceous version of a bullfight.

When the female Triceratops charged at him fiercely without thinking, he put down the body of the young Triceratops and dodged sideways swiftly, leaving her empty-handed.

While the female Triceratops was turning its head clumsily, Chu Xu suddenly swung out his claws, attaching fluid energy to the claw blades. In an instant, he tore seven or eight criss-crossing cracks on the female Triceratops's bucket-thick right hind leg!
The scales of the female Triceratops were hard and rough. Although the wound caused by Chu Xu's front claws was not deep, it was bleeding profusely, and the blood-red color gradually permeated her entire hind leg.

"Moo~~!!"

The female Triceratops howled in pain, but the injury was not fatal to her. She quickly turned around, swung her giant horn back, and rammed out hard, trying to give Chu Xu a fatal blow.

Seeing this, Chu Xu still nimbly stepped back to dodge, which made the female Triceratops so angry that it snorted continuously, and its engorged neck shield turned red, looking hideous and terrifying.

"Roar!!"

At this moment, seeing a gap in the defensive formation of the Triceratops, Dragon Dad, who had originally planned to give up, seized the opportunity, made a surprise attack, and broke into their formation in one fell swoop.

The young Triceratops fled in panic because of Chu Xu's attack, and the adult Triceratops also fell into panic because of the sudden appearance of the dragon father, and their formation was in chaos.

At this time, they could no longer care about stopping Dragon Dad, and prioritized the safety of themselves and their children, trying to stay away from the two Tyrannosaurus Rex as much as possible. Dragon Dad's target was not the young Triceratops, but the female Triceratops that was fighting with Chu Xu, with his cold vertical pupils fixed firmly, a strong smell of killing rising from his body, showing the wildness and dominance of the king of dinosaurs!
The female Triceratops's field of vision behind it is blocked by the huge neck shield on its head and neck, which is its most fatal blind spot.

The father dragon who attacked the female Triceratops from behind bit her right hind leg which had been scratched by Chu Xu.

Compared to Chu Xu's claws, Long Dad's bloody mouth is undoubtedly more lethal.
With one bite, the hard and thick scales and skin of the female Triceratops were bitten through, and a large piece of flesh was torn off, revealing the jagged white bones!
"Moo!!"

The intense pain made the female Triceratops howl miserably. Her bloody right hind leg was all over the ground, and she almost lost consciousness.

"Crack!"

Dragon Dad moved quickly and decisively. His bloody mouth suddenly closed like a trap and bit the broken neck shield of the female Triceratops.

This time, the female Triceratops' neck shield could no longer withstand the powerful bite force of the dragon father, and was directly bitten through by the banana teeth, piercing deeply into the neck muscles.

While biting the female Triceratops' neck, the dragon father was also pushing her heavy body hard, like a bulldozer, trying to completely knock the female Triceratops to the ground.

With Dragon Dad as the main attacker, Chu Xu no longer needed to be a bullfighter. He also used all his strength to push the female Triceratops together with Dragon Dad with a fierce collision.

"boom!!"

The female Triceratops had lost its support point on one side due to an injury to its right hind leg, and its center of gravity was somewhat unstable.

Under the combined force of Long Dad and Chu Xu, her huge dragon body, which weighed more than four tons, was shaken and rolled sideways, falling to the ground like a golden mountain or a jade pillar.

Falling sideways like this basically sentenced the female Triceratops to death, and it became a fish on the chopping board, to be slaughtered by Dragon Dad and Chu Xu.

"Moo!!"

The rest of the adult Triceratops had almost stabilized again at this time, with the female Triceratops protecting the surviving young Triceratops. The male Triceratops let out low howls and tried to rescue the fallen female Triceratops.

"Roar--!!"

But when Dragon Dad raised his head and let out an earth-shaking roar, he frightened the group of male Triceratops that were ready to make a move. They dared not to take the initiative to offend, but instead retreated timidly.

This is the fear that comes from deep in the genes of Triceratops. Ever since the Psittacosaurus, the ancestor of ceratopsians that lived in the Early Cretaceous, the ceratopsians have always lived in the shadow of the Tyrannosaurus.

Not only in the Hell Creek Formation of North America, but also in every corner and every period of the Cretaceous period, the love-hate relationship between the ceratopsians and the tyrannosaurus was played out.

For example, the Zhuchengceratops and Zhuchengtyrannosaurus from the Singerzhuang Formation in Asia, the Styracosaurus and Daspletosaurus from the Dinosaur Park Formation in North America, the Pachyrhinosaurus and White Bear Dragon from the Prince Creek Formation in North America, etc.

The two enemies, Ceratopsians and Tyrannosaurus, have been inseparable since their birth. They co-evolved in a life-and-death competition with each other. One side strengthened its defense while the other continued to attack, and they became the two most prosperous dinosaur populations in the long Cretaceous period.
