After hearing Lu Yuan's words, no one took them to heart. They each took their belongings and returned to the camp before heading to the next location.

After a day's work, they had collected nearly ten second-tier crystals, and everyone looked delighted.

"Great! I didn't expect the crystals to arrive so quickly. Nine in just one day! If this continues, everyone will be able to use crystals in just a few days!"

“That’s right, Lu Yuan. I think we can continue this business in the long term. Look, we don’t even have to lift a finger. In the past, it would take at least a day to kill one prey, and sometimes two days if we encountered a difficult one. It would take a whole day to get just one. Now we can get nine at once. This is a big business!”

"Yeah, yeah! I think we can finally get the freedom to use second-tier crystals. I just don't know when these bison herds will leave, or if they'll stay! I really hope they fight it out as fiercely as possible, so we can earn more!"

Seeing everyone's joyful faces, Lu Yuan was also filled with happiness.

He certainly hoped that the research would lead to more conflict, so that his group could reap the benefits.

So far, no military personnel have come to investigate this area, so they have practically taken over all the business on the entire grassland.

If they can't achieve second-tier crystal freedom while guarding such a precious land, what's the point of it in the future?

However, when Lu Yuan saw the few crystals on the table, he felt that they were still a bit slow.

So he looked up at Chen Yan while eating.

"By the way, how long has the bison migration been going on? Could they have stopped here for about half a year?"

Chen Yan stroked her chin and pondered for a moment before saying softly, "Well, the migration time of bison herds is roughly based on climate change. Every six months, they need to find a suitable pasture."

Sometimes, because they eat so much, they devour all the nearby grass, so they choose to migrate. This depends on the amount of grass available in the local area!

After listening, Lu Yuan nodded slightly. He was thinking that if all the bison accidentally left, their business would not be able to continue in the long term.

Although Lu Yuan did not intend to keep searching for second-tier crystals here, he would at least try to get as many as possible, since second-tier crystals would still be useful to them.

But how can we better obtain these crystals?

"Could we make our drones a little bigger and improve their battery life? Look, they only fly for a short while before having to return to base. This is having a huge impact on our work efficiency. Do you know any ways to increase the drone's flight distance and the time it takes to fly?"

Shi Quan, who was squatting to the side, ate his meal while lost in thought.

After a while, he shook his head again: "We've tried it before; if we make the drone too big, it's very likely to be spotted by birds of prey in the sky."

These birds of prey have a particular fondness for small creatures, especially small wild animals, which are their best prey!

At this point, Lu Yuan looked at Chen Yan again and asked, "Hey, who do you think is the fiercest bird of prey on the entire grassland?"

"Of course it's the golden eagle, no doubt about it. Golden eagles are among the fiercest birds of prey. They fly fast, have plenty of stamina, and are incredibly strong. They can even catch prey that is heavier than themselves!"

After hearing Chen Yan's words, Lu Yuan pondered for a moment and asked again, "Then, compared to the vulture, who is stronger?"

"Hmm? You mean we can develop in the direction of vultures in the future?"

"That's right. Vultures are scavengers, and they usually target dead prey, which is very useful to us."

We're looking for dead prey, and so are they. Wouldn't it be wonderful if we could find a vulture to help us?

After hearing Lu Yuan's words, everyone around him fell into deep thought.

Lu Yuan was right. Vultures are scavengers; they specifically target prey that has already been killed by other predators and then gnaw on the leftovers.

So everyone immediately imagined a scenario: attaching a surveillance camera or locator to the vulture so that they could pinpoint its location more quickly when it was eating.

Then find the location of the bones and take the prey's skull away. This is more efficient and you don't have to worry about running out of power.

So, when everyone finally understood what was going on, they all looked at Lu Yuan.

Lu Yuan glanced at everyone, then looked at Shi Quan: "This should be achievable, right?"

Shi Quan nodded vigorously, his face full of excitement: "I'll do it right now, right now! This method is definitely working."

As long as the communication information is sorted out, there shouldn't be any problems. We just need our first high-powered battery; nothing else is required. I recently acquired a transformer over there, which should be sufficient for our needs!

After saying that, Shi Quan excitedly ran to the garage and started fiddling with it.
