The response ability of the defense system is still very strong, of course, the premise of this defense system is also based on quantum communication, if there is no quantum communication technology that can communicate in real time, even if there is a strong defense system, relying on traditional electromagnetic wave communication technology, it is impossible to transmit the enemy's information back to the empire in time.

"The reaction was quite fast, and it was not in vain for the empire's large investment."

Li Fu looked at the virtual star map, the red dot on the star map was completely consistent with the position of the current spaceship, and the spacecraft was discovered as soon as it arrived here, which shows that the monitoring system is still very effective.

"Wu Gang, what do you need to go directly to Tu Xueli, what you have to do now is to build the entire monitoring system, so that a fly doesn't want to leak into the secondary spiral arm."

Li Fu told Wu Gang, and then the spacecraft flew at warp speed in the dark abyss very casually, and each time it would be discovered at the first time, and the position was calculated exactly at all, which was enough to prove that this system was still very useful.

Returning to the Sirero Galaxy, Li Fu quietly inspected the interstellar trade here in the Sirero Galaxy, which was very prosperous, and the civilizations from above the main spiral arm willingly accepted this huge scissors gap one by one, and exchanged the resources they had worked so hard to collect for the empire's powerful arms and weapons.

The situation on the main spiral arm is even more turbulent, over the years, the Kolov Empire has stepped up the plundering of various civilizations on the Orion spiral arm, which has made many civilizations under great pressure, and many times there is no way to complete the task pressed down by the Kolov Empire, so they can only choose to rob.

Coupled with the impetus of the empire's powerful arms and weapons, the entire Orion main spiral arm is like a huge battlefield, and there are flames everywhere, many originally weak civilizations have the advanced weapons of the Yanhuang Empire and have begun to retaliate and expand frantically, and those civilizations that are already powerful are even more so, wanting to have a larger territory and stronger strength.

The war on the main spiral arm has further promoted the prosperity of the empire's arms trade, the empire's arms weapons, powerful attacks, long attack distance, high attack frequency, the key is that even the energy shield, level 8 energy attack weapons are willing to be released and sold, many powerful level 3 cosmic civilizations are silently hoarding energy shield equipment and level 8 energy attack weapons.

What to do with hoarding these things, there is no doubt that they are used against the Kolov Empire, and according to past experience, once every 10,000 years, the Kolov Empire will increase the blood pumping of various civilizations on the main spiral arm to make up for the losses in the galactic North and South War.

In the past, there were no means and weapons to deal with the Kolov Empire, but now it is completely different, as long as there are enough level 8 energy weapons and energy shields, even if you can't beat the Kolov Empire, you can rely on the geographical advantage of the entrance and exit of the space-time ocean current to resist the exploitation of the Kolov Empire.

Therefore, whether it is an expensive level 8 energy attack weapon, an energy shield, a space battleship, or a level 7 and level 6 energy attack weapon that is relatively more intimate, it is a hot mess now, and it is simply in short supply, and the empire's military industrial enterprises are constantly expanding and producing at full capacity.

With this kind of hot trade, from the main spiral arm, a steady stream of massive materials were transported to the empire through three golden routes, which was also the foundation for the empire to carry out the great migration of the secondary spiral arm, the great expansion of the army, and the construction of a huge defense system, because there were enough financial and material resources to support it.

"Tsk, the arms trade has been the most profitable industry since ancient times, and without this arms trade, our empire would not be able to support everything now."

Yu Liang, who accompanied Li Fu to inspect the various areas of the second arm, looked at the dense space ports in the space of the Sirero Galaxy, and countless busy and abnormal spaceships, and couldn't help but let out a long sigh.

"Because arms are things that can directly increase the strength of a force, and power is a matter related to one's own survival, naturally, it has been the most profitable industry since ancient times."

Li Fu nodded, he was not too surprised by everything in front of him, among the seeds of civilization, he had seen too many such scenes, as a super civilized Han science and technology empire, ruling a universe, in the Han science and technology empire, a galaxy casually came out of it was not many times more prosperous than the current Sireluo galaxy.

"Brother Fu, where are we going to inspect next?"

This time, Li Fu plans to travel all over the sub-spiral arm, and this is only the first stop in the Xilieluo Galaxy.

"Go to the Imperial Institute of Quantum Science."

Li Fu thought for a while and said.

"Institute of Quantum Science? Brother Fu, do you want to see the research status of the quantum foam bomb? ”

As soon as Yu Liang heard it, he knew what Li Fu was thinking in his mind.

Because the Kolov Empire will raise troops to attack again at any time, Li Fu is also under great pressure, and the most important thing to inspect here in the Sirero galaxy is to see the construction of the secondary spiral arm defense system, and then inspect the Institute of Quantum Science, which is undoubtedly to see the research of quantum foam bombs.

"That's right, after all, the defense system is only able to detect the enemy, if you want to destroy the enemy, and reduce your own losses as much as possible, we need a cosmic-level mass killing weapon, and the quantum foam bomb is the most likely thing to be researched at present."

Li Fu nodded, the concept of the big killer was also put forward by Li Fu at the last high-level meeting, the original battle with the Kolov Empire in the Sirero system, although the empire won a brilliant victory, but its own losses were also Li Fu's heartache, Li Fu didn't want to repeat the mistakes of the past in the future war with the Kolov Empire, the big killer weapon is something that must be studied.

The spaceship that Li Fu was riding was constantly flying in the void, and the biological spaceship that combined the Empire's latest biotechnology with traditional technology was equipped with the latest 5-level warp engine, which could reach a range of hundreds of light-years at a time, and there was obviously no pressure on the secondary spiral arm.

With the expansion of the empire to the entire sub-spiral arm, the important research institutes under the Imperial Academy of Science have also moved out of the Centaur galaxy, and many important research institutes have occupied a galaxy as their own research base, and the same is true for the Institute of Quantum Science.

There are many advantages to occupying a galaxy alone as your own research base, first, it can be convenient to keep secrets, the entire galaxy is not open to the public, everything that comes and goes must be strictly checked, plus the selection of some remote galaxies, and the Imperial Time and Space Administration hides these galaxies on the star map, and the secrecy can be done very well.

The other is for safety, with the development of science and technology, all kinds of scientific experiments are becoming more and more powerful, and a careless accident may cause a devastating disaster, and it is much safer to let these scientific research institutions alone.

The galaxy where the Imperial Institute of Quantum Science is located is called the Quantum Cloud Galaxy, a name full of science fiction, but this name is only known to the senior management of the Empire, many scientists, even if they work and live in the Quantum Cloud Galaxy, do not know what it is called, and it is impossible to find the location of this galaxy from the star map released by the Empire, all the spaceships that come and go here are warp speed ships, and the space-time currents that connect the quantum cloud galaxy to the surrounding galaxies have long been blocked.

In the quantum cloud galaxy, Li Fu's arrival did not cause any movement, few people knew about it, and Li Fu didn't want to affect the normal order here because of himself.

"Your Majesty, teacher, why don't you notify me in advance, I'll be prepared."

Gong Gaofei, the dean of the Imperial Institute of Quantum Science, looked at Li Fu and Yu Liang who suddenly came to him, and hurriedly greeted him, this Gong Gaofei is Yu Liang's student, a genius scientist in the field of quantum research.

But at this time, he has red eyes, his long hair looks very messy, obviously he hasn't had a haircut for a while, and his long beard makes him look very old, but this Gong Gaofei can become the dean of an important research institute, his own Yuan Li cultivation is quite good, his skin is fair, and he still looks very young, these beards obviously haven't been shaved off for a while.

"Let's just come and see, don't say anything."

Li Fu gently signaled to everyone that he should not engage in it.

"Yes, yes."

Gong Gaofei instantly understood, and nodded again and again.

"Ah Fei, how is your research on the quantum bubble bomb lately?"

Yu Liang, who has always been disrespectful to the elderly, is very rare to show the appearance of an elder at this time, looked at Gong Gaofei, and asked with a smile.

"Still no, there is no substantial progress."

Speaking of the quantum bubble bomb, Gong Gaofei shook his head helplessly, this quantum bubble bomb is now the top priority of the research volume of the Institute of Quantum Science, and almost the vast majority of scientists in the quantum field have been concentrated to study the quantum bubble bomb, but there is still no substantial progress.

"Don't have too much pressure, a lot of things have to go with the flow, I think you better go and rest first, you look at your current appearance, where is there still the grass of Fuyun University back then."

Yu Liang looked at Gong Gaofei's appearance, and knew very well that once his student got serious about doing a research, he would really forget to sleep and eat, and he would be tireless.

"I'm fine, I've already gotten married and had children, I don't know how many children and grandchildren there are, where do I care about what I look like, it's better to have a beard now, so that I can look like an elder in front of my younger generations."

Gong Gaofei said disapprehantly, looking very happy to see Li Fu and his teacher coming.

"Your Majesty, teacher, I'll take you around first."
