The grassland is full of green grass, just past its calves. The breeze blows, and the grass sways and rusts.

"...The grassland long-eared velvet rat here has beautiful fur and plump meat. As the monster at the bottom of the food chain, they are also an introductory course for new adventurers. Being able to defeat the long-eared velvet rat alone is the first step to becoming an adventurer. In addition, the eggs of the long-eared velvet rat are very nutritious, and you can slightly improve your explosive power after eating - but you are not allowed to use a gun. I will demonstrate it first. Don't worry, I will reduce my strength to the same level as you."

After Ye Wan finished speaking, she took out a baseball bat from her backpack, listened for a moment, and then carried the baseball in one direction.

Ye Wan's running pace was very light, but it immediately alarmed a long-eared little dot in the grassland. The little dot ran quickly and made a clear mark on the grassland.

Ye Wan chased behind without any haste, and took the small spot to get a long distance closer every time she made a sudden turn.

The little one was very fast, but lacked endurance, so he couldn't run any longer. So it began to fight back to Ye Wan and rushed backwards.

Ye Wan waved the bat easily as if she was strolling in the garden, and just hit Xiaobudian's jumping leg. She immediately picked the little guy up and then knocked him out with a stick.

"That's it. Do you want to try?" Ye Wan threw the bat to Gu Qingchuan.

Gu Qingchuan took the bat, looked at the watch dial, and used the newly purchased infrared detection plug-in to patrol the grass.

"Don't look at me as if it was very simple just now. But in fact, it is very difficult to find the long-eared velvet rats hiding in the grass. If you want to find them..." Ye Wan was still waiting for a prompt, she saw Gu Qingchuan running quickly with the bat.

Ye Wan: “…”

Fortunately, Gu Qingchuan's performance was not that outstanding next time. No matter how weak the long-eared velvet rat was, it was a "warfare" and his strength and reaction speed were far beyond Gu Qingchuan's expectations. During the first encounter, Gu Qingchuan looked very embarrassed and clumsy in the face of the long-eared velvet rat's jumping and biting, and his pants were also cut by the long-eared velvet rat's claws, which was not as free and elegant as Ye Wan.

Ye Wan was afraid that Gu Qingchuan would be discouraged, so she quickly comforted her: "The training of adventurers cannot be achieved overnight. We are not in a hurry. Today you can catch one..."

"Catched!" Gu Qingchuan said.

Ye Wan: “…”

Gu Qingchuan grew up too fast.

Gu Qingchuan was very embarrassed when dealing with the first long-eared velvet rat, but when facing the second long-eared velvet rat, he was already very calm. The third long-eared velvet rat was just about to attack and was knocked down by Gu Qingchuan and fainted.

When the fourth long-eared velvet rat was reached, Gu Qingchuan first picked up a stone and then chased the long-eared velvet rat. The moment the long-eared velvet rat was about to run, he threw the stone directly in the direction of the long-eared velvet rat running, and smashed the long-eared velvet rat directly over with a stone.

Ye Wan: “…”

Gu Qingchuan fought faster and faster. From one of them at the beginning of fifteen minutes to one in the next minute, he could catch one in a total of twenty in half an hour! Ye Wan was stunned.

"Stop, stop! Enough, don't destroy the ecological balance anymore. Let's dig eggs." Ye Wan said.

Gu Qingchuan: "...Boss, do you have any misunderstandings about ecological balance?"

However, Gu Qingchuan still followed 32d happily, no, it was the boss lady who started digging eggs.

Digging eggs is also very simple: just find the rat hole and use a small shovel to dig it out. Generally speaking, parents of long-eared velvet rats will guard the hole entrance and fight desperately with the invaders. But now they are all wrapped in hunting bags with strings.

Ye Wan told Gu Qingchuan that the physical laws of the Yuan Universe are a bit strange, and it is difficult for living creatures to bring back to the real world. And bringing these meat and eggs back to the real world will also lose their magical effects.

So killing too much prey is just a waste.

"Have the boss's wife ever thought about placing a refrigerator at the entrance of the journey, or building a small farm, and then arranging people who are not adventurers but want to get the strength to come here to eat velvet rats and velvet rat egg dishes?" Gu Qingchuan asked.

Ye Wan glanced at Gu Qingchuan in surprise.

"You are very smart in business! But the people in Luzuo District probably don't have that much money. Rich areas, such as Boss Ma's Gaohua Tavern, are not bad... But they are not short of money. And there should be a lot of business in the rich areas."

After a meal, Ye Wan said to Gu Qingchuan: "I have been guessing whether you will be a young man from a wealthy area. Because your way of thinking about problems is really different from the poor people like us who have had a meal but no meal."

Gu Qingchuan shook his head quickly: "How could I be a rich man? It's impossible!"

Ye Wan did not continue to delve into it. The two began to allocate prey.

Because there were too many preys and they couldn't sell them for money, the two used the accidentally killed velvet rats as food rations, and the remaining ones were still alive and released them on the spot. The two dug a total of six nests, each of which had about seven or eight eggs. Gu Qingchuan and Ye Wan only took two at a time, and got a total of 12 thumb-sized velvet rat eggs, enough to eat.

In fact, Gu Qingchuan also dug a magical egg with a water-blue wave light, but Ye Wan asked Gu Qingchuan to return the egg. There are very few long-eared velvet rats who can do magic, so let them have some hope for their population.

Ye Wan took out the ingredients, and the two sat on the edge of the grassland and started to cook eggs and roast velvet rats, just like a wild survival version of the date.

But just as the two were having a happy meal, Ye Wan's cell phone ringed.

"Dingling ~ Dingling ~ Dingling ｈ (hang up)"

It was sent by Lei Zi.

The ringtone rang three times, which means "There is an emergency, and I don't have time to explain it in detail, in short, come and help my life."

Ye Wan frowned: "Lai Zi and the others are in danger? No way!"

After saying that, Ye Wan stood up, looked at Gu Qingchuan with a little hesitant expression.

"I'll go with you?" Gu Qingchuan said.

Ye Wan shook her head.

The situation where Lei Zi and his team of adventurers called for emergency help must be extraordinary. Gu Qingchuan went there and did not say that he was dragging his back, but he could only say that it was equivalent to killing him.

"Can you stay here and wait for me to come back? Promise me not to go anywhere. Although this is not a war zone, it is very dangerous for beginners to learn adventurers!" Ye Wan said solemnly.

"Okay." Gu Qingchuan said.

"I'm sorry." Ye Wan looked at Gu Qingchuan apologetically, summoned her antler horse, turned over the horse with a chic elegance, and quickly disappeared into the distance.

After watching Ye Wan's back disappear from sight, Gu Qingchuan became cheerful.

Just like a husband who broke away at home when his wife was out.

Because the boss's wife is not here, she can do some experiments that he has always wanted to do but has no time to do.

"Tin copper. Let's test the world's measurable physical parameters to correct simulation formulas." Gu Qingchuan said silently in his heart.

The first is gravity acceleration g.

g can calculate the gravity acceleration of the metaverse by picking up an item that has also been picked up in reality. Other macro parameters also have corresponding methods.

“Graining Acceleration: 9.81.”

"Atmospheric pressure: 1.01 standard atmospheric pressure."

"Kinetic energy e=1/2mv^2."

"Air density ρ=0.82g/l"

"Air resistance f=0.41*csv^2.2"

...

Wait! It seems that a strange formula has been mixed in...

Gu Qingchuan frowned and compared it with the real wind resistance formula.

The air density in this world is smaller than that in reality, and logically speaking, the air resistance should be smaller, but the relationship between wind resistance and speed is not square, but to the power of 2.2!

But don't underestimate the 10% difference between 2 and 2.2.

If the speed of a pistol bullet leaving the chamber is 400 m/s, then the wind resistance it will be 3.3 times that of reality! If it is an initial speed of 800 m/s, the wind resistance it will be 3.8 times that of reality!

If it is a hypersonic missile, the wind resistance it will be more than 4.4 times that of reality!

Including the resistance reduced due to the air density, we can know that any object with a movement speed of more than 10m/s will have greater resistance in the air than in reality, and the greater the speed, the greater the resistance!

No wonder kinetic weapons were discriminated against by adventurers...
