After a brief rest, Lin Feng set off from the cave early in the morning with the little silver wolf. If he had known that the little silver wolf was so powerful, Lin Feng would not have locked him in the doomsday watch in the first place. There was no one else in the Tianheng Mountain Range, so putting the little silver wolf outside and following Lin Feng could predict the danger in advance.

Continue to follow the flow of the clear spring and look for mandala flowers downstream. Zombies walking on both sides of the river bed in twos and threes may be the reason why the little silver wolf has not grown up. It does not have the aura of the silver wolf yesterday, so it did not see the zombies running away when they met Lin Feng and the little silver wolf.

Due to the reason why he was surrounded by zombies yesterday, now Lin Feng has to carefully observe the distribution of zombies around him every time he walks, and use a telescope to see if the zombies of all levels around him are reasonable. Lin Feng does not want to repeat the same mistakes.

Datura itself is rare. It is said that there may be only one or two plants in a mountain, and Datura grows in the valley, and the valley is the deepest part of the Tianheng Mountain Range. At present, Lin Feng's position is not far from the valley.

Along the way, Lin Feng minimized the number of shots he fired. Even though the guns were equipped with silencers, shooting casually would still attract a lot of zombies. Now that Lin Feng's energy level has been raised, even killing low-level zombies with a bayonet is much easier.

The Tianheng Mountains stretch for more than 100 kilometers, and the distance to the valley is tens of kilometers. Apart from unavoidable situations, Lin Feng tried to kill as few zombies as possible, and the main focus of his work was on finding mandala flowers. .

Until the third morning, Lin Feng finally came to the edge of the valley of the Tianheng Mountains.

What Lin Feng didn't want to see happened. Lin Feng didn't even see an ordinary zombie in the Tianheng Mountains and valleys.

If it was said that there were all kinds of zombies scattered here like other places, Lin Feng would feel more at ease. But seeing the current situation now, Lin Feng's heart was raised again.

This was the case with the mutated black panther I encountered before. At that time, there was not even a single zombie in a large area around, and then I met the mutated black panther.

This situation basically indicates that there will be high-level zombies or mutant beasts around. Only in this way, some low-level zombies will not appear in their range of activities because they are afraid of high-level zombies or mutant beasts.

The higher the level of zombies, the more intelligent they are, and the status level of zombies is very strict, and low-level zombies will obey high-level zombies. Ordinary zombies dare not enter the territory of some advanced zombies. However, this limitation is above level 4 zombies, and only level 4 zombies will mutate. Only mutated zombies can deter ordinary zombies. Zombies below the third level do not have this function, so it is normal to see some second- and third-level zombies together in the wild with zombie groups.

The same is true for mutated beasts. Zombies and mutated beasts are not originally based on an alliance, and often there will be fights between zombies and mutated beasts. Similarly, low-level zombies also dare not enter the territory of high-level mutant beasts.

In this way, it is possible to understand Lin Feng's current situation. There is not even a single ordinary zombie around, so it can be seen that there must be powerful zombies or mutant beasts in this valley.

Seeing this situation, Lin Feng couldn't help cursing secretly in his heart. Datura is not a precious medicinal material. As the saying goes, ordinary treasures of heaven and earth are guarded by powerful beasts. But mandala flowers are not very expensive, so it stands to reason that this kind of thing shouldn't happen.

Now Lin Feng is in a dilemma. If he goes back, this trip will be in vain, and all the dangers he experienced before will be in vain. But if you continue to go deeper, you may encounter powerful zombies or mutant beasts. Lin Feng was tangled in his heart and felt a little troubled.

"Roar!"

Just when Lin Feng was hesitating, a loud roar came from the depths of the valley.

Hearing this voice, Lin Feng's heart sank. It was obvious that the sound was not from a beast, but from the mouth of a zombie.

"Aw..."

At this moment, another roar came from the depths of the valley.

Hearing the previous roar, Lin Feng still hesitated, but after hearing the second roar, Lin Feng's face changed to reveal joy.

Without hesitation, Lin Feng walked cautiously towards the direction of the voice, while the little silver wolf followed behind Lin Feng, jogging.

From the first roar, Lin Feng could hear it coming from the mouth of the zombie. Moreover, it must not be a low-level zombie that can be heard from so far in the valley.

The second roar was made by a mutant beast, and it was impossible for a zombie to make such a sound. In the same way, the level of the mutant beast will not be low if the sound travels so far.

Judging from the strength of the two voices, neither of them is low-level, and there are no zombies in the entire valley, which is obviously the reason why the owner of the two voices just now is in the valley.

And listening to these two roars, it was obvious that they were both roaring. And the zombie and the mutant beast are not allies, which shows a problem, that is, the high-level zombie is fighting with the mutant beast.

As for the fight between zombies and mutant beasts, Lin Feng would naturally not be concerned about it. He could take advantage of this time to look for mandala flowers. Of course, Lin Feng had to find the mandala as quickly as possible and leave, otherwise, after the battle between the zombies and the mutant beasts, it would be more dangerous for him if he found Lin Feng.

There is only one road to enter the valley, no matter what, Lin Feng must go deep into the valley from this road. Lin Feng was looking for mandala while walking.

"Roar!"

As Lin Feng advanced, a loud roar came again.

Oops!

Listening to the direction of the voice, it was not far from Lin Feng. But there is only one road in the valley, and Lin Feng has not seen the shadow of the mandala along the way. Only by continuing to move forward can he find the mandala. And not far ahead is the place where the zombie roared. In this way, Lin Feng encountered another difficulty.

Turn around and put the little silver wolf in your doomsday watch. If the little silver wolf roars at this time, it may attract the attention of the other party, and it will be dangerous.

After picking up the little silver wolf, he walked slowly towards the direction where the zombies were roaring. Curiosity prevailed at this time. Lin Feng was very curious about what kind of zombies and mutant beasts could make the entire valley without zombies.

There was a dense forest in front of him, and he felt that he was almost close to the place where the incident happened. Lin Feng came to the back of a big tree and looked forward with his head.

Looking at it, Lin Feng couldn't help opening his mouth, regretting the decision he made just now, why curiosity made him come here to find out.
