Chu Fei's goal is very clear: stay alive and then complete the mission; in the end, if there is a chance, collect some fountain of life or other resources, if not, forget about it.

The previous missions have made Chu Fei understand that only those who can live a long life can live long. The dragon believed in by the Yanhuang civilization can be big and small, and a man can bend and stretch...

Chu Fei comforted himself like this. After all, 'Gou''s life comes first.

Chu Fei just followed Yuan Mingyuan numbly, walked up the steps step by step, and lined up to enter the dimensional space.

There was a scream nearby, and the security gate glowed red, and then someone was kicked out of the queue. At the same time, the security gate sounded an alarm: a thermal weapon was found.

One of the guards maintaining order in Feihu City sneered: "Idiot, this is a security gate with intelligent detection. Thermal weapons, modified clothing, even hormones, illegal drugs, etc. will all be checked out."

Chu Fei lined up silently; when he passed through the security gate, a light swept across his body, and then a countdown was marked on his bracelet, which showed: 10200+130 minutes.

10200 minutes is the time when the dimensional space is opened, which is 170 hours, a little more than seven days;

The next 130 minutes are the time when the exit is open, which is two hours and 10 minutes.

The moment the countdown appeared, Chu Fei suddenly felt nervous.

After all, we are risking our lives, so I would be lying if I said I wasn't nervous.

Taking a deep breath, he gently stepped through the security gate and came to the whirlpool. Chu Fei was very familiar with this kind of whirlpool. It was like this when he entered the dimensional space of the Flying Tigers before.

I took two steps forward again, only to feel that my vision was hazy for a while. When I regained my vision again, I found that I had arrived at a square, a square with a concrete floor.

But perhaps because of the passage of time, the cement floor has already been mottled and weathered, with cracks everywhere, small grass tenaciously protruding from the branches and leaves, and there are sparse dead grass on the ground.

Centipedes half a meter long crawled by, palm-sized beetles were flying in the sky, and dragonflies more than one meter flew by, buzzing like small fighter jets.

Could it be a mutated bug?!

Also, this is winter, shouldn’t bugs hibernate?

But after careful observation, we found that there was no ferocious appearance after the mutation.

Take another deep breath, the fresh and vibrant air flows like a clear spring, washing your body.

Chu Fei immediately noticed something strange in the air: "The active energy content in the air is too high, it feels like a super potion!"

Yuan Mingyuan spoke, "The active energy content in the air here can reach 1 million calories per cubic kilometer.

One calorie is about 2 micrograms, and 1 million calories of energy is equivalent to 2 grams of pure energy.

The active energy content of the outside world is 10 calories per cubic kilometer.

The energy density difference between the two can be up to 100,000 times.

Because of the increase in energy, the growth patterns of animals and plants here have completely changed."

"So much energy difference?!" Chu Fei was surprised, but then nodded thoughtfully, "Yes, this is a 'lake' after all.

Just like the water vapor content in the air and the amount of water in the lake, the difference between the two is as high as... more than four million times."

Chu Fei quickly calculated in his mind:

The mass of 1 mole of water is 18 grams, and the volume is 18 milliliters, cubic centimeters;

The volume of 1 mole of water vapor under normal pressure is approximately 22.4 liters, which is 1244 times that of 18 ml;

The water vapor content in the air at normal pressure is 0.03%, which means that the difference between the water vapor content in the atmosphere and the water content in lakes is more than four million times.

Therefore, the difference in energy density is one hundred thousand times, which is completely reasonable.

Therefore, there is a reason why the creatures here grow extraordinarily large.

Looking in the distance, outside the square, there are towering ancient trees. Many buildings have been overturned by vegetation.

There were constant exclamations, and the teenagers who entered here were attracted by the fresh and vibrant air.

Some people say that it would be great if they could always practice in such an environment; some others say that there is no need to explore at all and they can just practice here for seven days.

Chu Fei was still observing the surroundings, but Yuan Mingyuan spoke up, pointed in one direction and said, "Let's go here."

The ancient trees are towering and the grass is three to two meters high. The road is barely distinguishable and not very easy to walk.

There are not many roads around. Fortunately, as we move forward, forks in the road continue to appear, and everyone gradually separates.

Chu Fei and others followed Yuan Mingyuan for more than two hours before they were completely separated from the rest of the team.

At this time, Yuan Mingyuan breathed a sigh of relief and said, "There is a rocky hill ahead. Let's go there and rest for a while."

As he spoke, he sighed again, "Thankfully it's winter now. If it were summer, it would be difficult to walk here."

Everyone nodded.

During the break, Yuan Mingyuan turned on her bracelet, projected a map, studied it for a moment and said, "Our direction is basically correct, and we will proceed 100 kilometers in this direction."

Everyone, work harder. If the mission succeeds this time, we may find the fountain of life. It is worth any risk!"

At this moment, Yuan Mingyuan finally stopped pretending and confessed. Then she briefly explained what the Fountain of Life was.

In fact, this is a wise choice. We are not fools. If we don't give everyone a carrot, we will inevitably feel dissatisfied - the dimensional space will only be opened in two to three years. If we miss this opportunity, we will become adults and never have it again.

Opportunity.

Sure enough, after hearing the news, the eyes of the two little bees, Zhao Yuanhao and others all shone.

The forward speed increased suddenly, and it was just one hundred kilometers. Although it was a little difficult to move forward in the wilderness, for many semi-awakened people, one hundred kilometers was really not much.

Especially those ordinary semi-awakened people, their faces turned red with excitement, and their small universes were burning.

Only Chu Fei remained calm.

It was in this calmness that Chu Fei's eyes gradually locked on a little bee - one of the noble princes who was circling Yuan Mingyuan.

Compared to others, this little bee is a little too diligent and occasionally makes some unnecessary little moves.

In the last battle in the underground world, Chu Fei had seen many small moves by the Golden Dragon Team. Compared to the Golden Dragon Team, this little bee's methods were a bit unfamiliar and could not escape Chu Fei's eyes.

But Chu Fei didn't say anything, and the team continued to move forward.

There are occasional fights on the road, mainly involving some animals, but they are relatively ordinary.

Compared with the dimensional space that Chu Fei experienced last time, it can be said that everything is calm here.

After running like this for more than three hours, we actually advanced more than 30 kilometers. After eating, we rested for a while and continued to move forward, striving to reach the target as soon as possible to avoid a long night and many dreams.

After advancing for more than an hour, it was sunset, and the night in the dimensional space fell instantly - it was really night, and I couldn't see my fingers.

At this moment, Chu Fei's ears moved, and silver-gray nanoparticles seeped out from his skin, attaching to his ears and increasing the ear's receiving area, allowing Chu Fei to capture more subtle sounds.

It seems like someone is approaching!

Almost at the same time, the young man pursuing Yuan Mingyuan appeared behind Chu Fei.

His actions when he appeared next to Chu Fei seemed very natural. He was approaching naturally because he was in a hurry.

However, Chu Fei had already paid attention to this guy.

Under the wind of perception, Chu Fei "saw" the dagger in his hand.

Chu Fei remained silent, but quietly activated the "Butterfly Transformation" spell to shift the position of his heart.

After taking a few steps forward, the young man suddenly said, "Chu Fei, use the wind of perception to explore the front again. You can't see anything."

Chu Fei snorted, "I'm very tired. I have been using the wind of perception for more than an hour now, and my body is exhausted.

Besides, we weren’t just exploring, you also have infrared equipment.”

While talking, Chu Fei took out a bottle of super potion and was about to drink it.

But at this moment, the young man suddenly pulled out the dagger and inserted it into Chu Fei's heart.

"ah……"

Chu Fei screamed in fear, echoing in the night.
Chapter completed!
