Fang Xiaoyu asked strangely, "Why are you so sure?" ”

Xiaofeng replied, "It's because of him, the heart of Aquamarine." The heart of blue crystal is the core of the coltan energy vein, it is slowly formed due to the high concentration of coltan energy ore, this core is not just a vein can be generated, only the scale of the vein exceeds 10 million tons, it is possible to form a blue crystal heart. The newly formed blue crystal heart is only the size of a grain of rice, it will not only slowly absorb external ability to grow, but also allow the reserves of coltan energy veins to slowly increase, to this core is the size of a basketball, it is estimated that the ore veins here can exceed 100 million tons. ”

"100 million tons? That's an exaggeration. Fang Xiaoyu grew his mouth in surprise: "This amount of energy is enough to solve the shortage of coltan energy ore when we have just developed the universe." ”

"Shortage? With such a large vein, you don't need to think about ore shortages. But I still have a way to upgrade without ores. Xiaofeng said with some excitement.

Fang Xiaoyu asked, "What method?" Is it good for me? ”

Xiao Feng replied: "It's very advantageous, but it's very dangerous, even if I put this blue crystal heart into my world, as long as I put it in, even if I don't absorb any ability at all within a year, I can be promoted to level ten." But if that's going to happen, you'll have to get your hands close to the Azurite Heart and let me teleport it. ”

Fang Xiaoyu said: "Great, let's dig the columbium energy ore and immediately take out the blue crystal heart." ”

"There's no way, the coltan energy ore is very hard, and with your current level of technology, you can't cut it and use it at all." Xiaofeng replied.

"So what should I do?" Fang Xiaoyu asked Xiao Feng to give him an idea.

Xiao Feng said solemnly word by word: "You must touch the coltan energy ore with your hands, and you will automatically absorb the ore." As the ore is absorbed, it will sink into the underbelly. The Aquamarine Heart is not far from the cave walls here, and you can easily reach it. ”

Fang Xiaoyu asked, "Didn't you say that as long as I touch these ores, this cave may collapse?" ”

Xiao Feng sighed: "That's why I said that this mission is more dangerous, and I won't blame you if you choose to leave, but there is only one chance." Because the Azurite Heart is active in the veins, I don't know where it will go next time. ”

Looking at the slowly rotating blue crystal heart in front of him, Fang Xiaoyu gritted his teeth and said, "Okay, I'll fight this time, but you have to teleport the rest of the expedition team and the spaceship back first." ”

Fang Xiaoyu turned his head and said to the others: "You guys close your eyes now, I'm going to send you to the Chongshan Military Base north of the Etu River." Before the expedition set off, Fang Xiaoyu had expected to teleport the spacecraft back, so he demarcated a large military restricted area in the area north of the Chongshan Military Base across the river from Tianjin City, and built a large semi-underground isolation area here to house the spacecraft, which came in handy now.

When everyone heard Fang Xiaoyu's words, they thought that everyone was going to evacuate quickly, they didn't suspect that Fang Xiaoyu was just sending them away, but they wanted to stay, so everyone closed their eyes obediently.

"Start teleporting." Fang Xiaoyu gave Xiao Feng instructions in his heart, and Xiao Feng immediately executed this order. The entire spaceship, along with everyone in the expedition, quickly vanished into the place, and the place that had filled the entire spaceship became a huge hollow.

Fang Xiaoyu's feet landed on the ground made of coltan energy ore, and slowly walked towards the heart of blue crystal. "The heart of aquamarine, the essence of the entire coltan energy vein, as long as we get it, we can go home." Fang Xiaoyu muttered, walking towards the blue rock wall.

"Can we get started now?" Fang Xiaoyu stretched out his hands and made all preparations.

The breeze was very cautious, and it instructed, "Before I begin, I must tell you a few precautions. The Azurite Heart always heads towards the place where the energy of the entire vein is most intense, just like the pattern of water flowing downward. Once you start absorbing the coltan energy ore, the energy concentration here will naturally decrease, and the Azurite Heart will leave for a short time, so you don't have much time. Once the absorption process begins, you only have a maximum of ten seconds, and if it goes beyond that, the Aquamarine Heart will disappear and we won't have a chance. ”

"I know it, I have to catch it as fast as I can." Fang Xiaoyu nodded with a serious expression.

Xiao Feng continued: "I have to absorb it with all my strength in a while, such an energy flow speed will inevitably make your arm hurt, you must be patient. And after the absorption begins, the cave will begin to shake and collapse, you don't need to worry about your safety, if there is danger, I will teleport you out of the cave as soon as possible, even if the Blue Crystal Heart is not in hand. ”

Fang Xiaoyu nodded and said, "Okay, I'm clear, let's start." After receiving Xiao Feng's affirmative answer, Fang Xiaoyu stretched out his hands and grabbed towards the wall. The coltan energy ore was cold to the touch, giving people a feeling of relaxation, but soon this comfortable cold touch turned into a blazing flame.

After Fang Xiaoyu touched the rock wall, the blue silk threads seemed to be summoned, coming towards Fang Xiaoyu's hands, and the hard rock wall actually began to soften and concave. The blue silk thread spread down Fang Xiaoyu's hands to his elbows, this was due to the fact that Xiao Feng Lian's absorption speed was too fast, and the chip had no time to transform energy.

The blue silk thread that invaded his arm stimulated Fang Xiaoyu's nerves, and the huge energy quickly entered the chip, emitting a lot of heat during the operation, making Fang Xiaoyu feel a burning sensation, and at the same time, a sensation like a pinprick came from his arm, making Fang Xiaoyu almost faint.

Enduring the sharp pain in his arm, Fang Xiaoyu gritted his teeth and slowly pushed his palm forward, something surprising to Fang Xiaoyu happened, his hands actually slowly penetrated into the rock wall, as if he was probing into a soft gel instead of a hard rock wall. At this moment, Fang Xiaoyu intuitively felt that his feet trembled, and the entire cave shook, making him almost fall to the ground.

"Has it begun to crumble?" Stabilizing his figure, Fang Xiaoyu turned his head to look, and he found that the entire cave was cracking and shattering, and large pieces of ore fell one after another, quickly blocking the entrance of the cave not far away.

"Don't be distracted, grab the heart of the blue crystal." Xiao Feng shouted in Fang Xiaoyu's head.

Fang Xiaoyu hurriedly turned around and focused his energy on the heart of the blue crystal, at this time, the heart of the blue crystal had already begun to vibrate, as if he was about to leave this place. Fang Xiaoyu's hands were strong, and the entire forearm quickly entered the rock wall, and his fingers gradually approached the heart of the blue crystal, but the closer he got to the heart of the blue crystal, the more hot the temperature on his hand became, Fang Xiaoyu felt that his arm was about to catch fire, and the feeling of acupuncture gradually extended to the entire arm.
