The actual distance between the second target designated by Xie Guohui and the battleship was only about one light-year, but the star was not in the direction of Betelgeuse, and the fleet had to fly obliquely for one light-year to reach the second target.

If the distance between the fleet and Betelgeuse is constant, a light year of oblique flight is only a week's path closer to Betelgeuse.

An hour and eleven minutes later, the fleet was out of the speed of light.

Everyone looked around suspiciously, and everywhere they could see was red, and everyone invariably asked the same question: where are the stars?

"Xiao Xia, how far is our position off?" Ye Fei asked calmly.

When the battleship enters the superluminal speed, as long as the direction deviates slightly, the position away from the superluminal speed will be far away from the target, and there are many unknown factors affecting the course in the shock wave, and the battleship's unstoppable tremor makes the direction of each ship when entering the superluminal speed has obvious differences.

Fortunately, during the process of flying faster than light, each ship always turned on the magnetic engine, and the position of each ship could be detected through the guò magnetic sensor, otherwise when it was out of faster than light, no one in the sixteen warships would definitely be able to find anyone.

What is the point of deviating from the predetermined coordinates?

Xia Zhuoyan shook his head with a flat mouth: "Boss, the interference is too strong, there is no way to locate it, and I can't calculate the yaw number." "The position away from the speed of light is not near the predetermined star, but I don't know how far away from the star is, and I can't see the shadow of the star at all.

There is no target in sight, and the fleet cannot even correct the course.

Ye Fei had no choice but to turn his gaze for help to Professor Xie again: "Old Xie, do you have a way?" ”

Xie Guohui thought for a while and said, "Is there a way to test the direction of the shock wave?" ”

Ye Fei didn't understand what he wanted to do at all. I couldn't help asking, "Professor, what do you mean ......?"

"Even if we were to deviate, we wouldn't deviate too much, would we?" Xie Guohui asked.

"Under normal circumstances, it really doesn't deviate too much." Ye Fei replied carefully.

"The star I chose happens to be the largest one in the vicinity, although it is not as massive as the sun, but it is also 80 percent of the sun, its gravitational influence can reach an optical path of eight months, and the distance between the sun sheath and the star is about 60 to 80 astronomical units." Professor Xie carefully controlled the armor. Compare a large circle with both hands. "No matter how violent the shock wave is, it is impossible to turn a blind eye to such a large star, whether it is the confrontation of the solar sheath layer or the interference of gravity. There is always something that interferes with the operation of charged particles. As long as the location of the shock wave is measured, it is more confusing. That direction must be where the star is! ”

"Got it!" Ye Fei suddenly realized, "With this method, even if you can't see Betelgeuse." You can also guess the direction of Betelgeuse indirectly! ”

Professor Xie nodded with satisfaction: "That's it." ”

"Xiao Xia, do you understand?" Ye Fei raised his voice and asked.

"Understood, start detecting the direction of the shock wave right away."

"Liu Lei, send this news to the other warships, and let the other ships carry out the exploration together." Ye Fei ordered.

The detection direction of a battleship is limited, and all warships can be detected together, and a comprehensive analysis can be carried out from multiple angles, and the probability of finding an abnormal direction is several orders higher.

A few minutes later, the detection numbers of all the battleships were concentrated on the Xinyuan, and it only took more than ten seconds for the ship's computer to arrive at the accurate number.

The anomalous area is above the fleet!

As soon as the results were announced, all eyes were on the panoramic screen.

Ye Fei faintly felt that there was a shadow on it that was slightly darker than the other directions, so he ordered the fleet to set off there, but out of usual caution, he used a short distance to fly faster than light.

After the fleet flew over about 70 astronomical units, everyone was pleasantly surprised to find that the red outside the ship was much lighter, and after another faster-than-light flight, the fleet finally flew over the sun sheath layer, and saw the vague shadows of the stars outside the porthole.

The heliosheath is not completely immune to shock waves, but it is protected by the star's magnetic field, and the place close to the star is much cleaner than in interstellar space, and the stars at least twenty or so astronomical units away are no longer so indistinct. But no matter which direction you look, it's still a red color.

"Is the yaw number jù out?" Ye Fei asked.

"It's out!" Xia Zhuoyan immediately replied, "Yaw distance...... 0.33 light years. ”

"So far?" Ye Fei was surprised, "It seems that the impact of the shock wave on the flight is much stronger than we expected...... However, the position of the star can still be faintly seen from 0.3 light-years away, and the shock wave does not seem to be as thick as I thought. ”

As he spoke, he turned his gaze to Professor Xie.

"Of course." Professor Xie smiled slightly, "After the shock wave flew more than 200 light years, it was much worse than when it just erupted, in fact, the color of the shock wave we saw was very light, but we were inside the shock wave, and there was a lack of reference nearby, and the shock wave on an astronomical scale gave us the illusion that the shock wave was thick." ”

"I see." Ye Fei felt that he had grown a little more knowledge.

The fleet gradually approached the star, and the outline of the star became clearer and clearer, but Xia Zhuoyan looked like a ghost: "Boss, something is wrong!" ”

"What's wrong?" Ye Fei didn't notice anything wrong at all.

"You see, we are now less than two astronomical units away from the star, and at such a close distance, the impact of the shock wave is not much, but the picture is still so blurry......"

"Is the dust carried by the shock wave sticking to the lens?" Ye Fei's gaze stayed on Professor Xie as he spoke.

"How is that possible?" Professor Xie smiled suddenly, "The shock wave is the sum of matter produced by the explosion of a supernova and propagating at the speed of light, can this thing fly out of the shock wave at the speed of light for more than 200 light years?" ”

There is no need to answer at all, everyone knows that this is impossible.

Professor Xie continued: "In my opinion, it is probably the high-energy particles carried by the shock wave that eroded the anti-radiation glass of the ship's surface. ”

There are two kinds of radiation-related optical glass, one is anti-radiation optical glass, and the other is radiation-resistant optical glass, the former is used to manufacture shielding and window materials in nuclear industry, medical field and other industries; The latter is used in the manufacture of optical instruments and peep windows under high-energy irradiation.

Radiation-resistant optical glass has very little effect on visible light, similar to colorless optical glass, and radiation is ubiquitous in the universe, so the lens of the optical system of the battleship and other places that need to use glass materials on the surface of the warship are generally used in the latter.

However, although both types of glass can resist radiation for a certain extent, radiation is not completely ineffective on the glass, and it is clear that Professor Xie believes that the lens of the optical system has been severely damaged in the shock wave. (To be continued......)
