The explosion was so powerful that even though it was several kilometers away, the shock wave of the explosion still caused considerable damage to the camp.

After the aftertaste of the explosion dissipated, Su Wanxia immediately tried to contact others to confirm everyone's safety. In the end, only Xian Qianhua and Yan Sichen were in the camp.

Shen Yinuo, Xiaoxiao and Chu Xiaoming are all somewhere outside the camp, and they cannot be contacted for the time being.

"Can you determine what caused it?" Su Wanxia asked Samantha.

"The preliminary judgment is that the explosion was caused by the rupture of a highly compressed energy tank, but we are not sure where these explosives came from." Samantha quickly collected a large amount of useful data from outside the camp, and compared it to get the conclusion corresponding results.

Yan Sichen frowned and asked, "Could it be caused by the crash of the spacecraft?"

"The spacecraft crashed?" Xian Qianhua was stunned, and she asked Samantha, "Have any UFOs been detected approaching?"

"No, the explosion came from deep inside the earth's surface."

"Deep under the surface?!" This is more disturbing than a spacecraft crashing.

"Go take a look?" Yan Sichen suggested.

"Let's go." Su Wanxia had already planned this, but before leaving, he calmly said, "Sister Hua, can I ask you to stay at the camp?"

"Ah? Just let me stay here alone?" Xian Qianhua was a little unhappy.

"Isn't there still Samantha?" Su Wanxia said with a smile.

"Oh ho? Why do you still need me here when there is Samantha? Let's go together." Xian Qianhua had no intention of staying.

Su Wanxia had no choice but to agree.

The three of them changed into space suits with integrated exoskeleton systems, brought weapons, ammunition and various devices for collecting data, and then drove two terrain vehicles to the scene of the incident.

On the way, they finally contacted Chu Xiaoming and Shen Yinuo.

Fortunately, when the explosion occurred, they were in the Cuckstone Isthmus, thirty kilometers away from the center of the explosion, and the explosion did not have any impact on their outdoor activities.

However, I heard that Su Wanxia and the others were rushing to the explosion area, and Shen Yinuo and Chu Xiaoming were also rushing here.

…

In less than five minutes from the camp, Su Wanxia and the others arrived at the edge of the explosion area.

The impact crater was shallow but very large, and the entire explosion area looked like frozen ripples.

Samples collected from the periphery showed that this was a special energy residue that even Samantha didn't recognize. They were very clean, and of course their destructive power was amazing. Through the model demonstration of the calculation core, the thing that caused the explosion was probably only the size of a cherry.

This shocked Su Wanxia and others because they never expected this thing to be so small.

Continuing deeper, the undulations on the ground become more and more dense.

In the center of the explosion, Su Wanxia and others saw a blazing "spear" that was still rotating slowly.

It is 18 meters in length and 25 meters in diameter. It is red in color, with its spearhead pointing toward the ground, hanging twenty-five centimeters in the air, and at an angle of ninety degrees to the surface.

"What is this?" Chu Xiaoming saw this "spear" with the help of the recorder on Su Wanxia's shoulder.

This is what Su Wanxia and others want to ask.

Everyone consciously stood far apart.

Radiation detection showed that the amount of radiation at the center of the explosion was close to zero, which surprised Yan Sichen because it was impossible for such a large explosion to leave no radiation at all.

However, the energy amplitude data on Xian Qianhua's side showed that it was approaching the peak, which meant that the thing in front of him had not "calmed down" and it was still active.

"This thing is in very unstable condition and is likely to cause an impact. I think we should withdraw it first," Xian Qianhua reminded.

Su Wanxia looked at the spear. Although she didn't know what it was or where it came from, she felt a sense of déjà vu in her heart.

Just when Su Wanxia came closer to take a closer look, with a harsh "buzz", the spear suddenly rose into the sky and disappeared without a trace in the blink of an eye.

Everyone was dumbfounded.

Su Wanxia responded quickly, "Track its location, Samantha!"

"It's already being tracked, but it's about to leave my limit detection range."

What?!

Su Wanxia was shocked again.

It took less than ten seconds from the time he watched the spear take off until it left Samantha's extreme tracking detection range.

Three hundred kilometers in ten seconds?! A spear flying at the speed of light?!

Three minutes later.

"Lost target." Samantha tried her best, but it was too fast.

Yan Sichen looked up at the sky for a long time and said, "It's about to rain and the storm is coming... I think something like this will happen again in the next few days. We have to prepare in advance."

When Su Wanxia heard this, she looked at Yan Sichen, who also looked up at the sky, but the thoughts in her heart were completely opposite to Yan Sichen's.

What he felt was not the turbulent weather, but the sky was clear after the rain...

…

Ten days later.

Su Wanxia, ​​who had just gotten up and was reading an ancient book, was startled by a loud noise.

This time the explosion occurred thirty-seven kilometers east of the camp.

When the five-person expedition team arrived at the center of the explosion, they found a spear that was almost identical to the last time, except that it seemed to be dimmer than the one they saw before.

Based on the last experience, the five people did not get closer. They waited quietly at the edge of the explosion area.

Sure enough, shortly after the explosion, the spear soared into the sky again, and once again escaped from Samantha's tracking range at a speed approaching the speed of light.

The same thing happened twice in a row in less than half a month. To say it was just a coincidence would be a bit unreasonable.

So this time, Su Wanxia and Chu Xiaoming decided to take the space elevator to the star port in Mars orbit, where they planned to install a new magnetostatic lattice radar to track these mysterious spears.

The installation process was relatively smooth.

And after the installation was completed, what was very disturbing was that Samantha's first extraterrestrial scan found multiple unknown objects floating in the orbit of Mars within a radius of 155 kilometers centered on the star port.

Through pattern collection, it was initially determined that they should be the wreckage of some kind of aircraft. However, from the analysis of the data, not only Su Wanxia and the others could not identify what kind of aircraft it was in the human space program, but they could not even be found in Samantha's database.

to similar aircraft.

…

"Do you think... could it be the wreckage left by aliens?" Chu Xiaoming asked Su Wanxia.

Su Wanxia was not very sure. He could only barely discern the shadow of aircraft as aircraft from these wreckage, and indeed he could not completely conclude that they were the remains of damaged aircraft.

"Not necessarily, unless we can collect some and take a look." After Su Wanxia finished speaking, she asked Samantha, "Samantha, how feasible is it for us to implement the recycling plan?"

"Less than 20," Samantha responded.

"Oh...that means there is still hope. I think we should take a gamble." Su Wanxia rubbed her hands and then looked back at Chu Xiaoming.

Chu Xiaoming was stunned for a moment and then looked at Su Wanxia in disbelief and said, "Brother, are you crazy? Are you betting on a chance of success of less than 20? Have you lived enough?"

Su Wanxia was silent. He looked at the dark space outside the star port. After a long time, he smiled and said, "I have indeed had enough life. Days like this, every day is like wandering in the dark woods.

I have had enough of being tortured by those endless stories every day...can you still endure it?"

Chu Xiaoming stopped talking. He knew what his brother was thinking, and he didn't think he should be called hypocritical at this time.

In fact, only people who are emotionally deficient will think that people with rich emotional experiences are hypocritical, and there is nothing to be proud of in that kind of rhetoric.

He folded his arms across his chest, covered his mouth with one hand and remained silent for a long time before saying, "But we can't tell Yinuo and the others about this, just the two of us know about it."

Su Wanxia's eyes lit up.

"certainly."

…

"There is a 20 chance of success, a 675 chance of the machine being destroyed, and there is some uncertainty left... Hmm... your death roulette is really big." Samantha was preparing the preliminary work for Su Wanxia and Chu Xiaoming.

I also didn’t forget to complain about them both.

Su Wanxia put on her helmet and said, "When the space elevator was built, the probability of success in the first trial run was less than 0001, but those lunatics still got on it themselves to prove that their design was perfect. Compared with this, a probability of 20 is enough."

Big."

"Yeah, that's right, but they have a chance of survival. As long as you fail once, you will die without a burial place." Samantha continued to complain.

Chu Xiaoming laughed, "You can't defeat her! But, Samantha, you can say something nice and send us some blessings."

"Okay, okay, I will pray for you, and you'd better be smarter. I'm not sure how long I can hide it for you."

"Don't worry, help us prepare champagne, we'll be back as soon as we go." Chu Xiaoming said and immediately entered the spacecraft.

Su Wanxia also followed, but before the spacecraft started, he re-determined the location of the wreckage, and then he said to Samantha, "If something really happens, remember to seal the elevator, and you must not allow any accidents to spread to the camp."

Go over there.”

"OK, all right."

…

Su Wanxia and Chu Xiaoming were still inexplicably excited as they started the "recycling" operation again after many years.
