"So, what amazing and shocking discovery did you make?"

Fang Xu's eyes twitched repeatedly as he asked Lu Yongchang word by word.

Lu Yongchang chuckled and stretched out his hand to drag a holographic image.

With a few strokes, he sketched out a simple space-time model.

"Everyone, we have overlooked an important issue."

"When the curvature engine is started, under the action of two opposite gravitational fields at the front and back, a large number of particles will be sucked into the gravitational field in front of the starship."

As he spoke, Lu Yongchang tapped an area in the projection with his index finger.

"Eventually, these particles will converge in front of the curvature bubble."

"As the curvature navigation time increases, the number of particles will continue to accumulate."

"At the same time, during the process of curvature navigation, the energy they contain will continue to accumulate!"

"Wait!" He Bilin frowned and interrupted Lu Yongchang, "Where does their energy come from?"

"Warp drive?"

"Yes." Lu Yongchang nodded and confirmed He Bilin's words, "I just checked the energy consumption of [Warp One] after entering the curvature state, and found that it was slightly higher than I expected."

"At first I thought it was an error."

"Now it seems that this is not an error, but these particles are playing tricks."

"This is equivalent to additional resistance that the curvature bubble needs to overcome as it advances."

He Bilin nodded thoughtfully.

"I probably understand."

"When starships exit the curvature navigation state, they can still maintain the curvature navigation state for a short period of time because the particle mass and size are much lower than that of the starships."

"At this time, because the particles are still in the curvature navigation state, ordinary observation instruments cannot observe them."

"Moreover, it contains a lot of energy. Once it encounters an object blocking its progress, it will..."

He Bilin suddenly opened his palm: "Bang!"ъìqυgΕtv.℃ǒΜ

"It looks to us like we've been attacked by some mysterious attack!"

"But...Professor, how to verify this?"

Lu Yongchang smiled and pointed at the giant holographic projection in front of him: "Let's do the math."

"The interval between [Warp One] exiting the warp navigation state and the observation starship being attacked was 3.13 seconds."

"Resume the distance between the two."

"Exactly enough to get the speed of the attacking object: 1.1c!"

Hearing this, He Bilin quickly lowered his head and did some calculations.

"It's true!" Looking at the results in the holographic projection, he shouted in a low voice with some surprise.

Lu Yongchang laughed: "So, before proceeding with curvature navigation, we need to confirm the safety of the channel."

"Once any macro obstruction appears on the waterway, the consequences may be catastrophic."

Fang Xu on the side also added: "That means that in planetary systems with relatively rich interstellar matter, curvature navigation is strictly prohibited."

"certainly."

Lu Yongchang thought for a moment: "Not only within the star system, but also between star systems, we need to be more careful."

"After all, we currently do not have corresponding super-light observation methods."

"professor."

In the distance, Tao Yuda's voice came: "I have an idea."

"Do you think this characteristic of the curvature engine can be used to make weapons?"

Lu Yongchang was silent for a while, nodded, and then shook his head.

"Okay, but it seems...it doesn't have much effect."

"Before attacking, it needs to accelerate over a long distance to accumulate energy."

"In actual combat, it would be more efficient to use a curvature engine to launch anti-matter bombs."

"A weapon against low-level civilizations." Tao Yuda said softly, "If we want to absorb the other party as a subordinate civilization, the curvature engine should be a good weapon."

"Professor, think about our initial reaction."

"At that time, the Lator civilization did not use such methods against us." Tao Yuda shrugged, "Of course, the sailing distance of their flagship was not enough to trigger this effect."

"But what if..."

"Professor, what do you think will happen?"

"At least, the morale within the civilization will become a huge problem!"

Lu Yongchang's face changed slightly.

After pondering for a moment, he nodded: "In that case, I'll leave this research task to you."

Then, he turned and looked at the old man with gray hair standing not far away.

"Academician Cao Liangcai."

"You will be responsible for the task of modifying the existing starships."

…

After leaving the laboratory, Lu Yongchang, with the help of the robotic arm, directly boarded the robotic arm robot that had been waiting at the door.

The robot took him and drove quickly towards Lu Yongchang's office.

rear.

He Bilin looked at the robot's retreating back with envy.

"Xiao He, where is the robot you applied for?"

Fang Xu asked in surprise as he walked out of the laboratory door.

"...Academician Fang, my application was not approved." He Bilin looked at Fang Xu with a complicated face as he climbed onto the back of another robot.

"Oh, I'm sorry, I forgot."

Fang Xu smiled and raised his eyebrows at He Bilin: "Come on, make a few more big projects, and I will approve your application."

He Bilin: "..."

…

After returning to the office, Lu Yongchang quickly sat down in his seat.

"Zero, close the door!"

As he finished speaking, his consciousness had sunk into the depths of his mind.

Technology tree space.

In the mottled background, the technology tree outlined by white lines is particularly bright.

Looking at the extremely bright cursor, Lu Yongchang breathed a sigh of relief.

Curvature navigation technology has passed the "verification" of the technology tree.

A bright white line flows out of the cursor and stretches upward along the dim passage.

[Primary Gravity Shield]

【Grand unified theory】

These are the last two technologies for the fourth-level civilization to enter the fifth-level civilization.

Looking at the fog at the top of the technology tree, Lu Yongchang calmed down and focused his attention on one of the dim cursors.
