In the past 50 years, the biggest gain of Asgard is not the abundance of resources and funds, but the success of the experiment of the fourth-generation warp engine.

Nuwa has a large amount of space data, and with a lot of space theories in this universe, on this basis, Yang Xiao has finally caught up, in the past 50 years, led a team of more than a dozen people, is focused on the improvement of the warp engine, in the twentieth year, the 9.99 warp engine research and development was completed, the speed reached nearly 8,000 times the speed of light.

Then thirty years, on the basis of this third-generation warp engine, the fourth-generation engine was finally developed, the space jumper, in fact, the space jumper is equivalent to the ten-level warp engine, because its movement effect in a short period of time is too good, reaching hundreds of thousands of times the speed of light, so it feels like a space jump.

However, the materials required by the fourth-generation warp engine are too harsh, and the entire Asgard Palace can be made according to the recorded stock materials, and it can make up to 200,000 at most, and these resources are not only for the spirit ship, and finally the fairy palace is ready to make 50,000 Golden Dragon-class spirit ships, which can play a role in raiding.

The third-generation engine can not be mass-produced, which must also use a few rare materials with scarce reserves, in the case of existing material technology, no substitute has been found, so according to the reserves, it can produce seven or eight hundred thousand ships, and finally under the argument of Tianfang, Ma Lao approved the production plan of 400,000 ships.

In addition to the engine technology, the shield technology combined with the research of the Demon's silver-white ghost mothership and the research of the Spirit Array, a new attached shield was invented, which can not only defend against the impact of ion and particle weapons, but also can be defended against most of the energy weapons. Combined with the strengthened solidification of the spirit ship's shell, the attack power of the energy-type weapon against the spirit ship is almost zero, and unless it is hit directly through the jet port in the tail, there will be almost no traces left.

There is also the evolution of weapon technology, after combining the technology of energy weapons, the spirit pill cannon has made several variants of energy weapons, which are extremely powerful, and the most powerful black hole star destroyer cannon will explode with a diameter of about 5,000 kilometers, becoming dust in the universe, and finally under strict control, only ten of them were made and installed, and the related technology was sealed, this thing is too scary, if it spreads, the whole universe will have fun in the future.

......

"There are two questions in front of us now, should we go all out to open up the core area of the Tianqiao Star Domain, or start fighting the remaining half of the Sky Explosion Star Domain?"

The strength of the entire fleet has risen to a higher level, but in terms of numbers, it has not changed much, and there are also significant savings in military spending.

"Actually, it doesn't matter if the two aspects are done together! The Tianqiao Star Domain is mainly a ground force operation, and now that the forward base has been built, just advance slowly, while the Sky Storm Star Domain is a fleet battle, and there is no conflict!"

"Also, I suggest that the Skystorm Star Domain be brought down quickly, so that it can be connected with the defense line of the Tianping Star Domain, and we can carry out a second vigorous enclosure movement!" Li Shimin's eyes were about to turn into amethyst coins.

However, it is also that the Tianping Star Domain has nearly one-third of the defense line due to the connection with the Heavenly Storm Star Domain, if this line of defense is not done well, the enclosure movement will be like the Heavenly Sword Star Domain at the beginning, encountering various problems, although now the Heavenly Sword Star Domain has been defeated, and the enclosure movement has also begun for more than ten years, but the senses given to each family are not good.

"The Skystorm Star Domain is definitely going to be fought, how to fight it exactly?"

The Heavenly Storm Star Domain and the Tianping Star Domain are intersecting, and on the other side is the big tail of the Demon Domain, and for some reason, the Demon Race doesn't seem to dare to attack the Demon Domain, or the wild aura of the Demon Domain makes the Demon Domain disgusted or fearful.

"If we make a detour to the Demon Domain, and then outflank the rear of the Heavenly Storm Star Domain from the side and rear, can you eat all the demon fleets in the Heavenly Storm Star Domain, there are about one and a half million fleets here, accounting for almost one-third of the strength of the entire No. 2 force! If we can eat it, it will play a great role in the recovery of the next few star domains!" Hao Zhan's eyes lit up, and he seemed to have ignored the problem of the Demon Beast Domain all along.

"It seems that we have been fighting for decades, and we have forgotten that we still have the ally of the Demon Domain?" Tianfang suddenly remembered which cute little white tiger, and he didn't know if he would know himself when he saw him now: "Now anyway, there are places bordering the Demon Beast Domain in the Heavenly Storm Star Domain, we can contact the Demon Beast Domain and see if we can borrow the Dao or something?"

"Your Chaos Immortal Palace is familiar with a few demon kings, why don't you send someone to negotiate?" Hao Zhan looked at Tianfang: "If it can really be done, we can pull out half of the fleet of the Tianping Star Domain, at least there is no threat in the direction of the Heavenly Sword Star Domain for the time being, and now there is a brand new spirit ship behind, once there is a problem, you can enter the battlefield at any time, the speed is definitely faster than the demon race, don't worry about the problem of the back line!"

"When the time comes, from the direction of the Demon Domain and the direction of the Tianping Star Domain, we will outflank both sides, and then carry out a strong attack on the front, which can be regarded as a siege of three missing one, if the Demon Clan does not retreat, then stay here completely, if the Demon Clan retreats, we will focus on the actual occupation, and destroy the Demon Clan's fleet by the way!" Hao Zhan pointed to the handover of the two star fields on the star map.

"Don't you think it's strange?" Li Shimin asked: "In the past fifty years, the defense line of the Sky Storm Star Domain has been relatively peaceful, we have counted, in the past fifty years, there have been more than 20 large and small wars, and the loss of the demon clan's ghost mothership is estimated to be about 300,000, so according to the past, the second force can net increase the ghost mothership by more than 100,000 per year, so are these ghost motherships there?

Speaking of this, a few people were shocked, if the demon clan really has such an overseer, the number is incredible, Tianfang here called up the statistics of Nuwa's side: "The number of ghost motherships of the demon clan is really unchanged compared to before, this is something wrong, you need to send a reconnaissance team to find some waterways to observe some data!"
