"If the ancient waterway cannot be used, is there a backup plan?"

Fang Yuan asked after reading the information on this ancient waterway.

Interstellar warfare cannot be completely bet on luck, there must be a backup plan to make a decision.

Lang Xiaonian picked up a pen, drew a few lines on the holographic star chart, and then explained:

"This is a backup plan I considered. Count Arnis's nest is in the square seat κ153.

"We are now in γ670 Scutum, from γ670 Scutum to κ153, the current channel needs to pass through 16 hyperspace nodes, and the whole journey takes one month and 21 days.

"Among them, there are two hyperspace nodes with the farthest distance, 2 light-years apart, which is the voyage from λ780 to κ115.

"Judging by the speed of the Arnis Earl's fleet, this voyage will take about 24 days.

"Therefore, we can take advantage of the speed to arrive at the ruler seat λ780 in advance, and then find a hidden spot to hide.

"After the Arnis Earl's fleet passes in front of us, we will continue to move forward and hit their old nest, the square seat κ153."

Fang Yuan frowned after hearing this plan, and said, "This plan is a bit risky, isn't it?"

"Yes, this backup plan is indeed a bit risky, and the chance of being discovered is very high. Once discovered, we will be pursued by the Earl of Arniss fleet. However, given our advantage in the'photon transition', being pursued will There is a loss, but it should be able to escape. Moreover, this is only a backup plan, and it is only used when there is no better way." Lang Xiaonian explained.

Fang Yuan thought about it and asked, "If the ancient channel is still there, how long will it take to walk the ancient channel?"

"Normal 30 times the speed of light, it takes five months, three times longer than the current channel, so it will be abandoned." Lang Xiaonian replied.

An ancient waterway is three times longer than a new waterway.

It's really not surprising that this ancient waterway was abandoned.

"It takes five months to travel at 30 times the speed of light, can we have time?" A staff officer on board expressed doubts.

Even if there is a "photon transition", it can double the speed at most, and it will take at least two and a half months.

Moreover, the "photon transition" cannot be maintained all the time, so it will take longer.

"Neither battleships nor cruisers. As long as we are high-speed destroyers and be ghosts, we must be the ultimate." Fang Yuan made a decisive decision.

Generally speaking, the speed of the advanced civilization fleet is usually 30 times the speed of light.

However, this speed is determined by the slowest warship in the fleet.

And it is usually the battleship that determines this speed.

The characteristics of battleships are thick armor and fierce firepower, but their speed is relatively slow.

The current speed of the main fleet of advanced civilizations is about 30 times the speed of light.

However, if the fleet does not bring battleships, or even cruisers, just wait for high-speed destroyers.

Then this curvature speed is not 30 times the speed of light, but 60 times.

Under the acceleration of the "photon transition", this speed can even reach 120 times the limit.

Even if the "photon transition" cannot be maintained forever, it can be slightly reduced, and the average curvature speed can reach 100 times the speed of light.

If calculated at 100 times the speed of light, then taking the ancient waterway, it is true that when the Earl of Arnis arrived at the Shield seat γ670, at the same time it reached the Count Arnis’s old nest square κ153.

However, this has a premise, that is, the ancient waterway still exists and is available.

"If we take the ancient waterway, when will we leave at the latest?" Fang Yuan continued to ask.

"In extreme cases, we still have 15 days. However, in order to reserve some time to deal with unexpected situations, it is better to leave within 12 days." Lang Xiaonian replied.

"Twelve days is enough. Mortgage all our battleships and cruisers to the photosynthetic civilization, buy and lease high-speed destroyers from them, and upgrade our destroyer formations to increase the speed and firepower as much as possible." Fang Yuan immediately decided.

...

The next 12 days.

The human Tianqing fleet began to adjust the formation, mortgage all battleships and cruisers to the photosynthetic civilization, in exchange for high-speed destroyers, and upgrade the resources, weapons and equipment of the destroyer formation.

According to the agreement, Piggs' Perseus fleet will be stationed in Shield γ670 for three days.

When conducting defensive battles, the thicker the armor of the battleship, the better, the more fierce the firepower, the better. Speed ??is not the most critical factor for defensive defense.

Therefore, the photosynthetic civilization can exchange destroyers for human battleships.

This can enhance their combat effectiveness in defensive battles.

Both sides are considered to take what they need.

Piggs saw the Tianqing that was incorporated into the photosynthetic civilization fleet and was a little puzzled: "Miss Eve, what are you doing? Give us all the battleships, and you will only have destroyers.

"The firepower of these boats is completely insufficient, and there is no way to fight. When they encounter a normal Palerce fleet, they will be torn to pieces by their battleships.

"The fleet of all-destroyers is very lacking in firepower. This has long been confirmed by actual combat."

Eve was very confident, even arrogantly patting her chest and said: "What we lack is firepower? What we lack is the opportunity to touch the enemy."

...

In the next 12 days, the photosynthetic civilization was very serious about helping mankind upgrade their warships.

With the current technology of mankind, it is very difficult to upgrade battleships technologically.

However, with the help of photosynthetic civilization, it is different.

If the Earl of Arnis can be repelled, it will be very beneficial to the photosynthetic civilization.

So photosynthetic civilization dare not neglect.

In 12 days, the human Tianqing fleet reorganized 12 high-speed destroyers, forming a new "ghost fleet".

After the reorganization is completed.

Fang Yuan ordered the fleet to set sail, went in the opposite direction, and disappeared into the dark space of Shield γ670.

From the direction of disappearance, the human fleet looked like a fleet that feared Earl Arnis and fled.

After passing through the first hyperspace wormhole, the "ghost fleet" of humans is completely separated from the surveillance of higher civilizations, and then turns to disappear into everyone's sight.

The fleet began to fly in the direction of the ancient channel according to the direction of navigation directed by Lang Xiaonian.

"You can start the'photon transition' here, and you won't be discovered."

Lang Xiaonian used his finger to measure the distance of the channel, and after confirming that this location would not be discovered using the "photon transition", Han Youwei immediately started the "photon transition".

The fleet speeded up again, rushing to the ancient waterway in the square seat, drawing a bright light band across the sky in the dark and quiet deep space of the universe.

According to the propagation speed of light, this light belt will be discovered by other advanced civilizations in three months, but at that time, everything will be settled.
