Starting from Robinson Crusoe

As they set out towards the beacon hanging high in the sky, Chen Zhou discussed with Paul the possibility of avoiding another group of challengers on the road ahead.

Considering the other group had mounts, and the path to the beacon was particularly smooth, ideal for the Great Horned Deer to run, they ultimately decided to take a detour to avoid harassment.

...

Remembering the beacon’s appearance would inevitably attract challengers from all directions, Chen Zhou couldn’t help but feel a bit anxious.

Normally, he would consider the feelings of the three little Saw-toothed Tigers, putting them down to walk themselves when he saw them being uncomfortable in people’s arms.

This time, however, he disregarded the struggles and displeasure of the little guys, bundling them along with the marching pot, deerskin blanket, Hand Axe, and other heavy items onto his back and then sprinting forward.

Paul, relieved of any burdens and armed with only a Military Saber, dressed lightly and thought he could keep pace with Chen Zhou, only to find that even so, Chen Zhou’s speed and endurance were beyond his reach.

...

Chen Zhou, tall with long legs and large strides, moved quickly; it was more a jog than a mere walk.

He led the way with his head held high, and Paul only needed to follow behind.

For the first ten kilometers, Paul, who had undergone professional training, could barely keep up, but by the next ten kilometers, he was lagging more and more.

During this process, Chen Zhou slowed down multiple times to accommodate Paul, even helping him carry the Military Saber to minimize his load.

By observing the sun’s position, Paul roughly estimated their pace—

They had stormed twenty kilometers towards the beacon in less than an hour and a half.

To know that the world record for a 20-kilometer race walk is about 1 hour and 16 minutes, and race walking athletes have flat and unobstructed paths with no loads, their uneven grassland couldn’t be compared at all.

For Chen Zhou to achieve this speed while carrying tens of kilograms and stopping repeatedly to wait for him, he could probably easily break the world record.

Previously, Paul only felt that Chen Zhou’s strength, speed, and sensory acuity were unlike any ordinary person; it was only at this point he realized, this guy’s endurance was also far beyond normal.

During the training for the challenger reserve, through the materials in the textbooks and the "secrets" told by the instructors, Paul heard that heroes who completed a challenge could exhibit superhuman talents in various aspects.

Some had exceptional jumping ability; some had astonishing strength; some could hold their breath underwater for up to half an hour...

Each had their strengths, the medical school needed only to study their body structures, analyze their cells and unique DNA to unravel many medical mysteries, manufacture some imitation injections, greatly enhancing the physical qualities of Soviet soldiers.

However, these injections could only be administered one at a time, and soldiers with high tolerance could endure at most two.

The Soviet authorities have been trying to combine all the injections reasonably together to create a "simplified version of super soldier serum."

Looking at it now, Chen Zhou was very likely the serum prototype that the Soviet authorities dreamed of, and he was also an enhanced version of the super soldier, with physical qualities strong enough to affect the dominance of modern firepower over physical prowess.

Especially in combat zones where some electronic equipment is easily disrupted, soldiers like these could completely conduct solo incursions to execute decapitation tactics, even turning the tide of a small-scale conflict.

"It’s a pity, after this challenge ends, Chen Zhou will return to his world, and we may never meet again..."

...

The forced march continued until dusk.

When the beasts of the grassland began to stir, the Fear Wolves gathered, and predators like the Giant Hyena, Cave Hyena, and Saw-toothed Tiger left their lairs, Chen Zhou and Paul finally stopped.

By this time they had advanced about 50 kilometers, but still had not left the grassland, only getting closer to the distant mountains.

It was unknown what materials the Space-Time Administration Bureau used for the beacon or what technology it employed.

As the sun gradually sank below the horizon, the beacon hanging in the sky remained bright and dazzling, preventing the entire land from entering into night.

Due to this unusual change, the animals on the grassland appeared more restless than usual, even the usually steady mammoth herds were particularly uneasy.

Chen Zhou noticed a male Mammoth about 500 meters away, using its trunk to wrap around a branch of a large tree, then forcefully pulling it down, snapping off the whole section of the branch, until it stripped the tree bare, it then leaned closer to the tree, using its tusks to push the tree down alive.

Realizing the herd was acting atypically, Chen Zhou and Paul, who planned to set camp there, moved their campsite again to a higher Mound.

Usually, to avoid the wind, the two of them would light a fire on the side of the Mound, but this time, to better observe the movements of nearby beasts, Chen Zhou set the campfire on top of the Mound.

In recent days, the grassland had no rain, and the grass was nearing the end of its life, the entire grassland was particularly dry, so when building the fire, Chen Zhou had to be extra cautious, digging a ring of isolation around the campfire to prevent a prairie fire.

Whether this fire could endanger his and Paul’s lives was another matter, but once ignited, it would certainly spread over much of the grassland, affecting their advance.

...

Even if it was only two or three meters higher, the wind on the grassland noticeably strengthened.

The flames bent with the wind, providing only slight warmth, and even the speed of boiling water was slower than usual.

As for illumination—

Tonight, as well as the next half month or so, there probably was no need to consider night lighting issues.

The "new sun" hanging in the sky, although not radiating warmth, was no less bright than the sun in terms of brightness.
