At least by the name of Ye Wudao, it is relatively convenient for her to be able to go to various borders.

As for the price, it is naturally to help Ye Wudao to kill the beasts, and the four Eternals of the Red Dust Palace actually have hatred for the beasts.

He refused to help Ye Wudao before, just because Tianzun Yunshang was not to be provoked.

Staring at the map, Ye Wudao moved in his heart and suddenly thought of something.

"Drone."

Everyone was dumbfounded.

"What drone?"

"Desolate Heavenly Immortal, what are you talking about?"

"Is it a worldly thing?"

Ye Wudao smiled slightly, looked at Xiejiao, and asked, "Do you know what I think?"

Xie Jiao was slightly stunned and fell into contemplation.

After a while, her beautiful eyes lit up slightly.

"I know what you're thinking."

"Go ahead."

"You need to investigate more boundaries and draw an up-to-date map, and the Yan family's technology is what we need. We can explore and draw new maps with that kind of cheap gadgets."

"That's right, knowing oneself and knowing the enemy will never end in a hundred battles. It's impossible for me to ask Bingwu and Wanshen for a map." Ye Wudao looked extremely serious.

"Even if they want to give me a map, I don't believe that the map in their hands is the latest. In that case, use a drone and let the Yan family try it."

"Let Yan Xiya come over."

"Yes!"

Soon, Yan Xiya came to the council hall and saw a huge map surrounded by everyone, and there were still many blank spaces, she immediately understood.

"Excuse me, Sect Master, is it about the map?"

Ye Wudao nodded: "Don't know the enemy, that's a big taboo, don't know the terrain and orientation, it's also a big taboo, know yourself and the enemy, and we won't be in danger in a hundred battles. We only know ourselves, but we don't know the enemy's side."

"In today's battle, we are actually observing everything we have passed, but the map drawn is not complete. Some places still need to be recalled, and the description may not be very clear."

That is to say, in fact, the maps they drew are not the most detailed, and they can only know what one is about.

Yan Xiya took a deep breath and looked at the many eternities around Ye Wudao, only to feel that terrifying energy, as if it could shred everything, which shocked her a lot.

But she quickly adjusted her mind and said respectfully: "My Yan family is ready, we use the spirit stone as the driving force, and the maximum range of exploration can reach thousands of kilometers. If we use the power of the avenue as the driving force, the range will be bigger."

Ye Wudao frowned, squinted his eyes, seemed to think of something, and murmured: "The power of the avenue..."

I used to patronize the Yan family to build forts and projectiles, but I forgot that projectiles can be carried on other vehicles. If they fly in the air, they can raid the interior of the beast. Wouldn't it be surprising?

Although Ye Wudao understands that the beasts must also have strong investigators, they will not let the tribe go deep into their hinterland, and they will find out in advance.

But once the number of drones increases, what can the beast know about something that costs little anyway?

"You can't use the power of the avenue as an energy source, the power of the avenue will be discovered." Ye Wudao said solemnly.

"Then, there is no other energy." Yan Xiya hesitated.

Obviously they have more Shocking Weapons, and even have a special resource that can be used as an energy drive.

This kind of energy Ye Wudao can also guess, it is the energy related to fusion, this is the most terrifying weapon, in the world, it is a big killer.

After coming here, it actually has a great effect.

If this energy is used, the exploration of the drone will surely be extended a lot.

"Disguised as flying insects and other small things, make more and experiment." Ye Wudao ordered: "Give you three days, I know you may have prepared in advance, so you can take out anything that can come in handy. Go and try."

"Yes!"

"In addition." Ye Wudao thought for a while and said, "I need a map that goes from the border to the dark place for thousands of miles."

"The bigger the distance, the better, I need it."

"Yes." JrNovels.com
