It's reasonable for me to have a two-way foil for a second-level civilization, right?

……

a few minutes ago.

[Earth number] inside.

Seeing the ever-shrinking distance between the two fleets, everyone present secretly sweated.

Although they are not on the front line, their every order determines the life and death of countless soldiers on the front line.

"It always feels... a little weird."

A faint voice sounded from the side.

Before Lu Yongchang could react, Zhao Zijie beside him trembled as if he had been electrocuted!

"Fuck!"

Zhao Zijie looked at Gao Yang who was sitting next to him in horror, and shouted in a low voice, "Gao Yang, don't!"

Hearing this familiar name, Lu Yongchang only felt his heart skip a beat.

He still deeply remembered the last time Gao Yang spoke.

"I..." Facing Zhao Zijie's stop, Gao Yang's lips trembled a few times, trying to justify himself or herself.

The originally serious Zhao Zijie couldn't hold back at all: "At this critical moment, don't talk, okay?"

"Ahem!" Looking at Gao Yang whose eyes were full of anxiety, Lu Yongchang's eyes flashed with helplessness, and he coughed lightly to interrupt the communication between the two, "Gao Yang, tell me first, what's wrong?"

"Professor, so far, the other party has not produced anything new except the gravitational bomb. Don't you think it's a bit strange?" Gao Yang hastily opened his mouth to express his doubts.

Hearing this, Lu Yongchang was taken aback.

like……

Is this the case?

As a Level [-] civilization, so far, except for the gravitational bomb that was short-lived some time ago, the Bosa fleet used weapons and equipment similar to the human fleet for the rest of the time.

"Maybe there is a limit to the use distance of the gravitational bomb?"

Fang Xu interjected from the side: "The Bosa fleet used the gravitational bomb just now when the drone swarm was close to the face."

"We have reason to suspect that the stability of this gravitational bomb is not high enough to support long-distance launch missions."

Lu Yongchang didn't reply, just frowning and looking at the real-time picture in the holographic projection.

The fleets of both sides are charging forward with all their strength against each other's firepower.

Everything looks so normal.

"Fang Xu, have you observed any abnormal gravitational phenomena?"

Lu Yongchang pondered for a moment, and asked.

"Not yet..." Fang Xu said while turning his gaze to the holographic projection beside him, "Wait!"

Looking at the data in the holographic projection, the expression on his face gradually became serious.

"Not right!"

"What a problem!"

Fang Xu's words lifted everyone's spirits.

In less than a second, the atmosphere in the command center had become tense.

"What's going on?!" Lu Yongchang frowned, and his tone suddenly became serious.

"The probe has just discovered abnormal gravitational fluctuations in the Bosa fleet." As he spoke, Fang Xu projected the holographic projection picture in front of everyone.

Lu Yongchang looked at the gravitational fluctuation data on the screen, with deep doubts in his eyes.

"No, it's not a gravitational bomb reaction."

As he spoke, he raised his hand, swiped a few times on the holographic projection in front of him, and called up some data.

"Everyone can take a look."

"The gravitational fluctuations caused by the gravitational bomb are more violent and rapid than it."

"The two are not of the same magnitude at all."

"This pattern of gravitational fluctuations..." Lu Yongchang raised his hand and touched his chin, and said thoughtfully, "It's a bit like the gravitational fluctuations before the Lator civilization entered curvature navigation..."

Speaking of this, Lu Yongchang was already stunned.

A crazy idea suddenly flashed in his mind.

Before he had time to think about it, he turned around and shouted at Zhao Zijie who was beside him:

"quick!"

"Evacuate the fleet!!"

"Let all the warships disperse!!!"

Zhao Zijie was stunned.

Based on his trust in Lu Yongchang, he directly pressed the communication button of the entire fleet without the slightest hesitation.

"Attention all units, evacuate the fleet!"

"Repeat, immediately disperse the formation!"

Not long after the words were spoken, an extremely dazzling light appeared in the [Golden Crow] battleship group!

Almost at the same time, a harsh siren sounded in the [Earth] command center!

"warn!"

"Anomalous gravitational fluctuations detected!"

"Anomaly area: 1, 3, 9, 16..."

The ever-growing bright red fonts jumped into the eyes of everyone present, accompanied by dazzling rays of light, shaking everyone's hearts.

"Fuck!" Looking at the several gravitational anomalies that soared instantly in the holographic projection, Lu Yongchang knocked hard on the console in front of him with an ugly face, "Gravity bomb!"

On the side, Zhao Zijie's face was slightly pale, he pressed the communication button of the whole fleet, and shouted in a slightly hoarse voice.

"Attention all units, immediately disperse the formation!"

"First Fleet, Fourth Fleet, Seventh Fleet, please call back!"

"..."

"Yong, Yongchang..." Fang Xu's pupils trembled slightly, and he muttered in a low voice, "Hey, what's going on here?"

"All detectors have found no trace of the gravitational bomb reaching the fleet!"

"How on earth did they do it?!"

Lu Yongchang looked bitterly at the holographic projection in front of him. In the projection, there were a few inconspicuous gravitational fluctuation data.

He was silent for a while, then spoke softly.

"Curvature Navigation Technology."

"They apply curvature navigation technology to shells."

"I should have thought of it earlier." Lu Yongchang's eyes were full of regret, "This kind of attack method that exceeds the speed of light is the biggest gap between the fifth-level civilization and the fourth-level civilization!"

"Chi..." There was a loud voice from the speaker beside him.

"First Fleet, First Fleet received, please tell me!"

"Fourth Fleet, the Fourth Fleet received..."

"..."

Familiar voices sounded in the command center, bringing back a lot of blood on everyone's faces.

Outside the porthole, the dazzling glare slowly dissipated.

The tragic situation of the [Golden Crow] fleet was also clearly presented in front of everyone.

"Zero, report the battle situation."

Lu Yongchang said with difficulty.

Zero's electronically synthesized voice is as calm as ever.

"First Fleet, the battle loss rate is 23%."

"Fourth Fleet, the battle loss rate is 19%."

"..."

"The cumulative loss of warships is 623."

In the command center, there was a dead silence.

In just a few seconds, the human fleet lost more than 10% of its warships!

ps: It should not be from Xiaoyang, so it's not a big problem.

Chapter 551 Lu Yongchang: Simple Calculation

Unlike the human fleet, the Bosa fleet at this time is full of celebratory atmosphere.

"Commander, the results of the battle have exceeded our imagination!"

"They don't know the power of curvature weapons at all!"

Listening to the voices around him, Commander Bosa also slightly relaxed his originally stiff body.

It raised the two pairs of forelegs on its chest and moved a little.

Looking at the chaotic enemy fleet in the picture, there was a hint of regret in its eyes: "Unfortunately, we haven't fully mastered this weapon yet."

"Guaranteeing the stability of the curvature bomb is still an unsolved problem for us."

"Otherwise, we can use curvature bombs outside the star system."

"This is the hard-to-bridge gap between the fifth-level civilization and the fourth-level civilization."

While speaking, Commander Bosa gestured in front of him: "They don't even know where the attack is coming from!"

"Commander, if we fulfill the Lord's order this time..." the large stick insect said in a low voice, "We might be able to get some of the Lord's gifts again."

"Just like last time." The large stick insect turned its head and glanced around, and said in a lower voice.

Hearing this, Commander Bosa's eyes suddenly lit up!

It's extremely impressive.

In the last Gift Ceremony, the Bosa civilization successfully obtained a unified theory, and then became a fifth-level civilization!

If there is another gift ceremony like this...

Thinking of this, the breathing hole on the side of Commander Bosa's body instantly enlarged.

It breathed hard, and spewed out streams of scorching gas from the breathing hole.

"continue!"

"Continue to use the curvature bomb before they react!"

……

"Anomalous gravitational fluctuations detected!"

"The abnormal gravitational point is generated inside the Bosa fleet!"

Before the [Golden Crow] fleet regrouped, the piercing sirens sounded again!

In the command center, it has become a mess!

Every scientific researcher of related majors is engrossed in staring at the data sent back by various detectors, trying to find out the so-called laws from these complicated data.

On the side, the eyes of Zhao Zijie and the other military commanders were full of anxiety.

But no one urged.

All military commanders are extremely clear that the current battlefield cannot be saved by so-called tactics.

In the face of this brand-new attack method, the role of tactics is infinitely reduced.
