The two missiles exploded after they came into contact with the invisible barrier. The combined power of the warhead was still there. In an instant, the light of the explosion wrapped around the entire city, and the shock wave spread outward, so that the Blind Spot, which hovered hundreds of kilometers away, was also shaking.

However, this explosion did not produce mushroom clouds. The power of the explosion was evenly transmitted and diluted along the invisible barrier, but it did not successfully penetrate the barrier.

After more than ten minutes, the aftermath of the explosion had already spread to the distance and could no longer cause any turmoil. The Blind Spot was approaching the edge of the city and saw that the damage that seemed to be caused in the city was nothing more than some rockfall.

Lu Yu stared at the data detected on the screen: "The barrier does exist. Judging from the data, the 160,000-ton warhead cannot directly break through the barrier's defense, and the energy fluctuations caused to it are extremely small.

To directly break through the barrier, the defense of a real super bomb may require the use of a real super bomb, but the Blind Spot does not carry a weapon of this level.

Whether the barrier technology has always existed or our actions have aroused the alertness of pioneer civilizations, it has been further activated, which will have an impact on future plans.

At least we can't do whatever we want as we did before."

Julia said: "The more this happens, the more it seems to be valuable infiltrating. If you can help you steal this technology, it will also be of great benefit to our future adventures.

Take me to try to sneak into the giant flying monsters used by the ruling race, so that the chance of being able to successfully penetrate should be greatly improved!”

"Nothing can stop us from cracking their technology and then blowing up their city!" Lu Yu also became interested and pulled the blind spot all the way up.

After being attacked, the Giant Tower City began to be martial law, and hundreds of small flying monsters were organized into dozens of flying teams to inspect in different directions outside the city.

The monsters in that circle of guards suffered some minor injuries in the explosion, but now they are still rushing on the ground to search for possible threats.

A giant flying monster left the field at the top of the giant tower, and another giant flying monster flew towards the giant tower city.

Taking advantage of this opportunity, Blindspot accelerated to approach the giant flying monster. Julia jumped out of the Blindspot spacecraft and quietly hid in the shadow of the monster's crunching nest.

Julia's special ability successfully avoided the strict defense that could defend against ordinary nuclear bombs. This method of dimensional reduction in the dimensionality reduction strike really made the two of them a little obsessed.

After a walk around this magnificent city, Julia found that in many aspects, this place is actually no different from the most border and the most backward city.

Ascetics in religious temples gathered together to quarrel with the ruling ethnic group, the nobles who had just been attacked but were still singing and dancing, the busy engineers, and the ordinary residents who were busy.

The difference is that it is more magnificent, with more factories and social functional areas.

Higher-level monsters are produced here, and there are many powerful goods such as sickle heads that can become the main force invading the human world, and are also developing in monster factories inside the city.

Julia traveled all the way, and her most important goal was to have various high-tech technologies. She took Lu Yu's miniature robot subordinates from her portable space and went to the city to assist her in the infiltration work.

Remote-controlled bombs and time bombs are installed in inconspicuous but structurally active parts in the city.

This time Julia saw more social life in pioneering cities, and her evaluation of this was that she was completely uninterested.

Even if you cannot communicate, you can see in this city the bad habits that all civilizations have, such as greed and desires, such distortions and disguise.

After reaching the bottom of the city, Julia found a strictly guarded building, and the instruments she brought also showed that the energy fluctuated the most frequently.

After entering quietly, the inside and the outside are completely different.

The huge space inside was filled with blue fluorescence, and a creature that looked like a jellyfish was absorbed at the bottom of the city's energy source, and then extended tentacles continued to extend along the wall to the ground.

Julia followed her tentacles to find the point where energy waves emitted outside the city to form an invisible barrier.

"The energy barrier they use is actually made in the form of biological organisms? This is really incredible. Could it be that they use biotechnology to open wormholes, right?"

Julia couldn't help but sigh.

Lu Yu kept calculating the data collected by Julia, and then said: "I'm afraid you have to risk getting close to that 'jelly' monster. It would be best if you can collect some monster biological tissue samples."

"I'll try!"

The creatures that can generate super barriers undoubtedly attracted the interests of Lu Yu and Julia so much that they did not care whether they could obtain fragments of other technologies.

Julia ventured to lurk back to that space again. Here, because the "Jellyfish" monster is glowing all over and there is no other object, there is no shadow for Julia to use to lurk. It can be said that she is completely risking her life to collect samples.

But Julia didn't think there was anything wrong with this. As a hunter, all she had to do was to constantly challenge her limits.

She directly cut off a large piece of living tissue of the "jellyfish" with the hunting blade, then put it in a box and put it into a portable space.

And her rough actions seemed to have caused the monster's emergency response.

The regular blue light on the monster's body began to turn red and then flickered sharply, and the instruments that read the energy fluctuations also began to call the alarm.

"Julia, come out quickly!"

Julia didn't need Lu Yu to remind her that she had rushed out of the door quickly. At this time, she was discovered by the guards of the guards who controlled the monsters before she could even hide in the shadows.

A pioneer guard drove the small monster to attack Julia quickly.

Julia quickly took out her weapon, flashed by and killed a monster, and finally disappeared into the shadow, and then quickly rushed out of the giant city.

Due to Julia's actions, the city's energy barrier has become unstable. She escaped from the barrier guard and was rescued by the Blind Spot that had already arrived.

Lu Yu drove the Blind Spot toward the distance. At the same time, Julia also pressed the button of the remote-controlled bomb. Explosions began to occur inside the Giant Tower city. This time the energy barrier could no longer help them, and the entire city ushered in destruction.

In just a few days, Lu Yu and Julia drove the Blind Spot to destroy three pioneering civilization cities. The news was sent back to the Expedition to make everyone on the Expedition both happy and uncomfortable.
