Too fast! From the beginning to the end of the battle, from the moment the six black leopards pounced to the moment the last black leopard died, it actually took only about three breaths. The black leopard, a soul beast that lives deep in the mixed zone and has multiple soul skills, is definitely not weak. But in the battle led by Zhao Xin, it was killed instantly like a dead tree or rotten wood. This was not a fight at all, but a simple massacre.

Zhao Changtian came to Zhao Xin and said, "Good job, do you need a rest?"

Zhao Xin shook his head silently. Killing five black leopards was just an ordinary thing for him. He had no intention of resting at all.

"Okay, let's continue on our way." Zhao Changtian said.

On the road again, Zhao Changtian was still in the front, but his speed was obviously slower than before. Zhao Xin was not in a hurry. They were about to go deep into the mixed zone and gradually approach the core area. It was not a bad thing to go slower.

Continuing to go deeper, their good luck finally came. Although they occasionally encountered soul beasts along the way, and there were also some powerful ones, most of them were not particularly aggressive. In addition, according to Zhao Changtian's mental detection, they deliberately avoided them, so they did not encounter any major problems along the way.

They walked for three hours, and it was not until almost noon that they stopped to rest.

Zhao Xin stood there, observing the plants around him, with a thoughtful look in his eyes.

"What did you see?" Zhao Changtian came to him with a smile.

Zhao Xin said: "The vegetation here is more lush than before, and it can be seen that it is not new. It is more primitive than the vegetation outside. It is indeed sparsely populated! If I am not mistaken, we should be very close to the core area of ​​the Xingdou Great Forest, right?"

Zhao Changtian nodded appreciatively and said, "Yes, we are approaching the periphery of the core area. Going forward, we will enter the core area, which is the most dangerous area of ​​the Xingdou Great Forest. Even the fierce beasts in the fierce land will occasionally come to the core area. So, you must be careful and stay with me later. Look, this snake dragon orchid is at least a thousand years old. If it was in the outer circle, it would be impossible to appear. Because the snake dragon orchid has a fatal attraction to low-level soul beasts. It should have been eaten long ago. The fact that it still exists proves that no one needs them here, and the soul beasts that need them dare not enter this area."

It is much better to take classes on the spot than to study rotely. Zhao Xin listened and memorized carefully. For him, these are undoubtedly extremely valuable experiences. He is only a fifth-ring, and he doesn't know how many times he will come to the Star Dou Great Forest in the future. Knowing the core area early will definitely be of great help to his safety in the future.

After eating, in preparation for the more difficult journey ahead, this time the rest time was exceptionally long, a full hour and a half. Only after Zhao Xin adjusted his condition to the best did Zhao Changtian set off again.

Continue to go deeper. As expected, the surrounding vegetation changes gradually become obvious. Between some towering ancient trees, it even feels a bit dark because the treetops are too dense. The breath of life in the air has also become obviously richer. Zhao Xin can clearly feel that the vitality of heaven and earth here is much greater than that of the outside world. If you can practice here for a long time, it will be a great state for any soul master to improve his cultivation. Unfortunately, no one will choose to practice here, it is too dangerous.

The number of soul beasts in the core area is not as large as that in the mixed area. Almost all the soul beasts that can survive in the core area are the first-line soul beasts in the Xingdou Great Forest. Most of them live here alone or in family units. Because of their own strength and pride, few live in tribes.

Some particularly powerful soul beasts would carve out their own territories in the core area. Anyone who dared to enter their territories, whether human or soul beast, would be regarded as an enemy and attacked fiercely by them.

Therefore, unless it is a soul beast that believes it is strong enough, other soul beasts rarely enter the core area. Otherwise, it is easy to encounter a disaster of death.

After going deeper for about half an hour, Zhao Changtian began to turn and no longer continued to go deeper into the core area, but instead moved sideways.

The area of ​​the core area is much smaller than that of the mixed area. With the abilities of the father and son, if they run at full speed regardless of everything, they can run from the core area to the fierce place in half a day at most.

Of course, this is only a theoretical situation, and it can only exist in theory. All humans who dare to try have become nutrients for this forest.

"Roar!" A low roar sounded from afar, and Zhao Changtian immediately stopped and listened quietly. Then, there was another "squeak". Compared with the previous one, this one was much sharper.

"The sound is not far from us. It should be that powerful King Kong Bear." Zhao Changtian thought for a moment and said softly.

Even as he was speaking, the roars of the two soul beasts began to become more and more frequent, and more and more impatient.

Zhao Xin said excitedly: "We are lucky, we seem to have found it. Moreover, it seems to be fighting with another extremely powerful soul beast. This opportunity is really great for us."

Zhao Changtian warned Zhao Xin, “Don’t rush to approach. Their fight hasn’t officially started yet. Wait a little longer to avoid being affected.”

"Boom——" The fight finally began. Even though it was four or five kilometers away, the violent roar was still clearly heard. But the strange thing was that such a roar did not cause any birds to fly away. The soul beasts that could live in the core area were definitely not something that could be easily scared away.

"Boom, boom, boom..." A series of roars continued to sound.

The sound of collision in the distance became louder and louder. Fortunately, the two unknown soul beasts did not move during the battle, which could be seen from the spread of the sound of their battle.

"Don't worry. If I'm right, it should be a fight for territory. This kind of battle will not end in a short time. But it's not a fight of life and death. They will probably hold back. Let's wait for them to consume some energy. We will go over there." Zhao Changtian said calmly.

Zhao Changtian could easily deal with the two soul beasts, but this was the core area of ​​the Xingdou Great Forest. Who knew if a 100,000-year-old soul beast would suddenly fall from the sky? If such a problem occurred, the result would probably be unpredictable! Therefore, the first thing to do in the core area was to ensure that everyone's combat effectiveness was in the best condition possible.

Suddenly, a deafening roar sounded from a distance. The sound was so strong that Zhao Xin subconsciously covered his ears and took a few steps back.

"Heaven-shaking roar?" Zhao Changtian was surprised and finally identified what one of the two soul beasts fighting over there was.

"It should be the Sky-shaking Roar, and it has activated its strongest innate ability. Let's go." Zhao Changtian called out, jumped up first, and rushed forward.

A distance of several kilometers was only a very short journey for the two of them, even in the Star Dou Great Forest.

The roar that shook the sky really frightened Zhao Xin. He was still several kilometers away at the time! His ears were ringing. Not to mention that he was so close. This was completely a sonic attack. The representative soul beast with this ability was the roar that shook the sky.

The collision between the two soul beasts continued, and the frequency was becoming more and more intense. Finally, they entered Zhao Xin's spiritual power range.

The forms of the two soul beasts also appeared in Zhao Xin's eyes.

One of them was naturally Zhao Xin's target this time, a powerful King Kong Bear that was nearly 40,000 years old. Its body was covered with golden light, making it seem indestructible. Its punches and kicks showed the violence of a bear soul beast, but it was entangled by the soul beast opposite it and was even a little exhausted.
