Ning Xi took out a war beast chain to activate, and a small submarine with a length of more than ten meters appeared on the deck.

"This submarine is made of earth-grade materials. As long as it doesn't encounter a heaven-level monster, or encounters a group attack of earth-level monsters, one or two earth-level monster attacks cannot break such a defense."

"I also incorporated some deep-sea materials, so this submarine is very resistant to pressure. As long as it doesn't dive to a depth that even a heaven-level profound master can't bear, it won't be affected by the water pressure and gravity, and you can drive under the sea at will."

"You can also see that there are only ten positions in it, and the space is not large, so you can only sit and drive."

"But you are not here to have fun, but to find materials for experience and assessment, so this kind of small submarine is more suitable for you."

"If you encounter a monster attack, you can send the people inside to fight as long as you activate a special switch. It's easy to come back, and there will be no water leakage."

Ning Xi first introduced the functions of the submarine, and then said the price. "A submarine has 10 million power stones. Take what you want, and don't care what you don't want. Get off the boat and swim by yourself."

"What? Ten million is so expensive?"

"It's a bit overpriced."

"The price of a heaven-grade war beast is almost the same, Ning Xi, you are stealing people!"

Ning Xi rolled his eyes, "Is this submarine comparable to a war beast? Then why don't you buy a heaven-quality war beast and take you down there!"

All of them were choked up in an instant, the Heavenly Grade War Beasts do not have this function!

After sweeping the crowd, Ning Xi lazily walked to the submarine to open the hatch, "I'm really convinced of you, the arrogance of each big country is actually more stingy than the other."

"Look at me showing you the submarine's most powerful secret weapon, and see if you still think it's expensive." Ning Xi looked at the crowd with disgust, and got into the submarine.

"..." Everyone twitched the corners of their mouths, but Ning Xi was embarrassed to say that they were more stingy than each other. This was 10 million energy stones, not 1000. I don't know who got into Qian's eyes.

However, they were still very curious about the so-called secret weapon that Ning Xi said.

Ning Xi landed in the control room of the boat with her spiritual sense and flipped a few switches, and the small submarine she was sitting on was sent out of the cabin and appeared in the sea.

Everyone stood in front of the transparent floor-to-ceiling windows and stared intently.

I saw the small submarine driving extremely fast and flexible in the deep sea, and then a wave of strength spread around.

Before everyone could ask questions, a dazzling light burst out from the front of the submarine.

The group of rays of light went straight towards a large reef on the seabed in the distance, and then everyone saw that the big reef was completely submerged by the light group.

After the power light group dissipated, everyone saw that the previous big reef had disappeared, leaving countless gravel falling towards the sea, and their jaws could not help but be startled.

"This, is this the energy from that submarine?"

"My God! This power is so strong, it's almost the strongest blow from a profound master around the seventh to ninth rank."

"How did Ning Xi do it?"

"I felt the faint fluctuating aura of Lingyu in that power."

"I also felt it. It seems that this energy should be sent out at the cost of Lingyu." The presence of all the geniuses of various countries can still see a lot of doorways.

"Does that mean that as long as there is a supply of spiritual jade, such power can still be fired in bursts?"

"It's entirely possible, why hasn't Ning Xi come up yet! I really want to know."
