The sixth planet of β107 Perseus.

This is the planet closest to the capital of the Triad of Arden, except for the second planet.

The resource level of this planet is D, which is not recommended for mining.

On the resource star chart, such D-class planets are not classified as resource stars.

Because of the D-class resource star, the mining cost is too high, the amount of resources obtained is too small, and the waste generated is too much.

Therefore, D-class planets are generally regarded as planets with no mining value.

"Hey... Team leader, mark on the star chart that this planet is a D-class planet and has no mining value, but under my exploration ability, I found a mining engineering well." The ghost pilot was very puzzled. .

Xie Fengxing raised his brow and asked, "Where is it?"

"Just ahead, about two hundred kilometers."

The pilot stretched his hand in one direction.

He is the navigator of the Ghost and the explorer of the Ghost Team.

Under normal circumstances, the explorer has a broader vision than the awakened in other positions, and it is indeed more suitable to lead the work.

"Let's go and see."

Xie Fengxing made a decisive decision and led the ghost team through the Great Rift Valley and quickly approached the mining engineering well mentioned by the pilot.

It didn't take long.

The ghost team arrived not far from the mining engineering well and saw the engineering well built deep in the Great Rift Valley.

The navigator of the Phantom, using abilities to detect the inside of the engineering well through light reflection.

Ten minutes later, he reported: "Team leader, I saw it, it is the Star Source Mine. However, depending on the purity of the Star Source Mine, it is not necessary that the Star Source Mine of the Star Beast Planet is much better."

Star beast planets do have star source mines, but in fact, star source mines on star beast planets are between D and E in the resource star classification of higher civilizations, and have no mining value.

And the resource level of the sixth planet of β107 Perseus is D level, which is indeed not much better than the star source mine of the star beast planet.

"Isn't it that D-class resource stars have no mining value?" A team member asked.

Xie Fengxing pondered and shook his head and said: "The value of mining is not absolute. Whether there is mining value is actually the key to cost and profit.

"D-class planets do have no mining value, but there is a prerequisite, that is, the mining cost is too high, resulting in too much profit, or no profit.

"If the income can be increased and the D-level resource stars can also make money, then there will be a certain amount of mining value.

"In the mining cost, in addition to mining and purification, there is another cost that accounts for a large proportion, that is, freight."

The ghost pilot immediately nodded and answered: "Yes, in the Milky Way, mining resource stars often cross the star system.

"In this case, the time to transport resources and the energy consumed must be calculated in the cost.

"However, this sixth planet has an advantage, that is, it is very close to the capital of the triple star, and it is adjacent to the capital star No. 5.

"If you do this, the transportation cost from this sixth planet to the capital of the triple star is very low, and it is negligible.

"Looking at it this way, the transportation cost is omitted, so even for D-class planets, the mined mineral deposits still have certain benefits.

"However, looking at the mining engineering wells here, it seems that the level of technology is not high, and the profits should not be too high."

Advanced Civilization has a complete scoring system for rating resource stars.

However, in actual mining, transportation costs need to be calculated based on actual conditions.

Therefore, the sixth planet β107 Perseus, although the resource level is only D-level, but because of the low transportation cost, mining is indeed profitable.

However, mining revenue is not high, so there will not be high-end mining ships for mining, but some relatively low-end mining companies use slightly backward technology to conduct mining.

Take the technological level of Palestine civilization.

If it is a high-end mining project, engineering wells will never be used.

An advanced mining ship can complete all mining work.

While the ghost team was observing the sixth planetary mining well of β107 Perseus, a transport ship entered the planet's atmosphere, began to slow down and lower its altitude, and finally landed on a platform not far from the mining engineering well.

When Xie Fengxing saw this transport ship, his heart suddenly started beating wildly.

A dangerous thought suddenly appeared in his mind.

He looked back at the comrades in the group, took a deep breath, and said: "Our mission has not been completed. If the Xingyuan Mine transport ship here is heading to the Sanlian Star Capital, then this may be our last chance!"

When the group members heard his words, they immediately understood what he was talking about.

Everyone's breathing became heavy.

Xie Fengxing said solemnly: "This is our last chance to complete the task, and I have decided to make the last fight.

"However, basically there will be no chance of returning to Earth by doing so, so I will not force you.

"If someone is willing to be with me, then we will use our lives to accomplish our mission.

"If you choose to stay, it doesn't matter. If one day the living people return to Earth, remember to hand in our action files and don't let the sacrificed comrades have no names."

Everyone's breathing began to become heavy.

"Team leader, I am willing to participate. Even if I stay, I may not be able to live. The destroyer who hunted us will definitely get it back! Instead of this, it is better to let myself die more valuable." A ghost group 4 determined to follow. .

"I am going too!"

"I'll go too! The mission is not completed. Even if we can survive, there will be no hope for mankind and no hope for the family of the earth." Navigator Xiao Zhao stretched out his hand and shook Xie Fengxing firmly.

In fact, the will of each of the space soldiers who can be selected into the expeditionary fleet has been tested many times.

Everyone knows in their hearts that from the moment when the Purger civilization appeared, every step that mankind took was walking on thin ice, and any failure would cause mankind to lose hope of survival.

Therefore, when faced with the choice between life and death, they chose to fight their lives to complete their mission.

"If you can die with the triple star, it's worth it, I will go too!"

After Xie Fengxing pondered for a moment, he said: "You can't go all the way, you must keep one, and leave a spark for the ghost group. Xiao Zhao, you stay, you have the best talent and the youngest in the group, even if you leave the ghost, Also worthy of the position of fleet leader."

"Team leader!" Navigator Zhao Yifeng became a little excited.

"This is an order! You must stay, find a way to contact the fleet, report to the superior, our action plan." Xie Fengxing was tough, reaching out and pressing on Zhao Yifeng's shoulder.
