The equipment on the exploration ship was transported to this isolated island and started operations, it was already early in the morning.

At this time, Chen Jian slowly stood up from behind the reef and walked towards the direction of the cliff, preparing to start climbing the cliff and reaching the primeval forest above the cliff.

For such a long time, no ships came and no one appeared nearby. The wreckage of the yacht explosion had already sunk into the sea. It can be basically concluded that all traces were completely covered up.

The cliffs are very high and steep. If Chen Jian switches shapes, he can easily climb up.

However, Chen Jian did not do this, but climbed up in a human form with a backpack on his back.

Chen Jian knew very well that switching to the beast form would accelerate the consumption of nutrients stored in the body, while in the human form, that is, if not switching the form, it would not consume much stored nutrients.

Of course, everything has its pros and cons. Switching forms and increasing nutrient consumption will bring the benefit of saving time. Chen Jian can quickly climb to the top of the cliff.

On the contrary, if Chen Jian does this at this time, he will waste some time, but the nutrient consumption will be relatively less.

Although the cliff is very steep, there are places to rely on, which reduces the difficulty of climbing a lot for Chen Jian.

Chen Jian was not worried about any accidents. Even if he climbed to a high point and suddenly fell, Chen Jian would not be afraid, because he could almost say that he could complete the shape in an instant. Before falling to the end, Chen Jian could complete the shape in the air, so naturally he didn't have to worry about safety issues.

It took nearly an hour before Chen Jian climbed to the top.

After being infected by the virus, Chen Jian could feel that even under human form, his physical fitness improved. Before he was infected, Chen Jian would not be able to climb to the top of the cliff in one breath.

At this time, Chen Jian climbed to the top of the cliff. Although he was out of breath, he climbed up in one breath without stopping or resting.

Chen Jian was already on the edge of the primeval forest at the top of the cliff. However, Chen Jian did not immediately enter the primeval forest, but sat down at the top of the cliff, rested for a while, and looked into the primeval forest.

Although Chen Jian already has night vision ability, he can't see a very far area within his eyes.

The reason is nothing else. Not only are the trees in the primeval forest soaring straight into the sky, but they are still very thick, without any traces of human beings. It can also be said to be artificial planning. The trees grow very casually and are everywhere, directly blocking Chen Jian's vision.

Even if Chen Jian came to this primeval forest, he had a clear goal.

Because when Chen Jian watched the black and white documentary, although he was with Iga Lingko, others gave detailed explanations.

After the exiled noble couple had contracted the virus, her husband had to lock her up in a cave in the primeval forest!

Chen Jian’s goal is that cave!

After Chen Jian's breathing returned to a steady state, he walked into the edge of the primeval forest and began to climb a big tree in the edge area.

Not long after, Chen Jian climbed to the top, and half of his body poked out the area covered by leaves, and he could already see the area above the large area above the primeval forest.

Since it is a cave, it must be on the mountain. Chen Jian climbed to a high place in order to find the mountains in this primeval forest.

Standing high and looking far is undoubtedly a matter of no doubt.

Chen Jian's standing height was already high enough at this time, and he saw that the mountain range was also the only mountain range in this primeval forest.

The mountain does not seem to be very high, because only a part of the mountain top is exposed under the cover of the primeval forest.

Although Chen Jian was very far from the straight line of this mountain range at this time, the mountain was covered by a primeval forest, and the top of the trees was significantly contrasted with the top of the primeval forest. If the mountain was very high, most of the mountains would definitely be visible.

Only seeing some of the mountain tops means that the mountain must be not high, and the height is no more than 100 meters at most.

In addition, Chen Jian was away from the mountain range at this time, and the straight-line distance must be dozens of kilometers. The specific distance is difficult to estimate. The straight-line distance of dozens of kilometers can only be said to be a rough estimate.

Chen Jian identified the direction, came down from the tree, and headed towards the mountain range.

However, after walking for a while, Chen Jian stopped and frowned in confusion!

Something wrong with this primeval forest?

Chen Jian looked around, and it was quiet and there was no sound!

However, this is exactly what's wrong.

Since it is a primeval forest, there must be animals living in it. At night, it is time for many animals to move around, but Chen Jian didn't hear any sound.

This primeval forest is so quiet that there is no sound at all?

Even if there are no animals, there must be some insects or the like?

But there is no poisonous sound from any insects here.

To put it bluntly, there was a silence around him as dead as death!

At this time, Chen Jian not only had night vision ability, but his sense of smell and hearing had been greatly improved. Chen Jian was originally a trainee, and his hearing was much better than ordinary people. However, when Chen Jian's hearing was greatly improved at this time, he still could not hear any sound!

Chen Jian slowly shook his head and continued to walk forward.

There is a saying that goes, you are very skilled and brave!

This is the case with Chen Jian at this time. Even if there are ferocious beasts here, I am afraid they are not Chen Jian's opponent.

In other words, no matter what strange this primeval forest is, Chen Jian was not afraid and continued to move towards the mountain range according to his original plan.

A journey of dozens of kilometers is not something you can reach in a short time.

What's more, if you are in the primeval forest at this time, you will easily get lost.

Every time Chen Jian walked a distance, he would take advantage of the rest time to find a tall tree, climb to the top to determine the position, and then continue to move forward.

Fortunately, Chen Jian did not lose his direction and did not get lost in the primeval forest. After a few hours, Chen Jian walked almost half of the journey.

Chen Jian silently estimated the time. When he walked to the vicinity of the mountain range, he was afraid it would be until dawn.

While sitting under the tree to rest, Chen Jian listened to the movements around him. Just like Chen Jian had just stepped into this primeval forest, he had been walking so far, and this primeval forest was still silent like death.

What's going on?

Although Chen Jian didn't care, he also raised this question.

It is understandable that there are no living animals, insects and other animals in an area.

But after walking so far, there was no sound yet. Could it be that this entire primeval forest is like this?
