A large number of mechanical insects flew towards the deep underground.
They were moving very fast, and in a short while they had crossed the downward passage and entered a significantly wider space.
These mechanical insects can also see a long list of signs hanging on the wall before entering the large space.
The two best-preserved ones, one at the top, are plaques engraved with the name of the laboratory.
Sand Sea Laboratory
The other one was at the bottom, and there was a claw mark on it that almost tore it apart.
Lu Qianyu could only barely make it out.
Cooperation and Exchange between Two Ethnic Groups... Advanced Collective
Since there is no light source, the mechanical insects can only rely on their own night vision function to vaguely observe the scene in this space.
The height of this space is about five meters, and many ventilation equipment can be seen installed on the top.
But the length and width of this space are difficult to estimate accurately in a short time.
The layout around the door is basically a long table with drawers at the bottom and a display shelf-style laboratory table at the top.
There are also many laboratory tables connecting the ground and the ceiling placed uniformly on the left.
In the very center of the space, an open area was specially marked out, on which twenty dissecting tables were placed at widely spaced intervals.
Looking further away, there seemed to be other experimental instruments and equipment.
It was obvious that the place had been abandoned for quite some time.
The tables and chairs were covered with thick dust, and many of the reagents on the display shelves had begun to lose their original function due to being left there for a long time.
Some relatively valuable scientific research equipment was abandoned here for some reason.
The metal components that originally contained high-difficulty spiritual energy can now only sense a little spiritual energy fluctuation.
However, when these mechanical insects dispersed and carefully observed the laboratory, Lu Qianyu keenly noticed something unusual.
She noticed that the blood stains on some of the dissection tables were unusually fresh.
Some of these bloodstains were formed by splashing, while others were caused by dripping, showing a heart-pounding crimson color.
Moreover, judging by the state of these blood stains, the earliest one may have been formed the day before yesterday.
Although Lu Qianyu is not an expert in this field, he has been hanging out in the well-ordered Chongming City in recent months.
And he is also an intelligence worker.
This means that although Lu Qianyu has been working for less than a year, he may have seen more crime scenes than some soldiers stationed in settlements with good public security.
So, facing the dried blood, he could roughly guess the time and reason of its formation.
Lu Qianyu immediately realized that this laboratory was not completely abandoned.
At least recently, some people have used it.
He immediately began to control the mechanical insect.
Part of the search is to see if there are any experimental data or record papers that have been missed.
The other part is to find a hidden location and lie in wait, so that they can monitor the movements here at any time in the future.
He had a hunch that he could dig up some important information in this laboratory.
…
The undercover intelligence team in Shahai City has made progress, but Zi Sui, who is doing experiments in Yin City, is stuck.
"Boom! Boom! Boom!"
The sound of explosions that came one after another was easily covered up by the thick fog.
The explosive power of the composite He Yu increased significantly with each debugging, and it only took a few hours for it to remain unchanged to the present day.
Zi Sui stopped bombing the abandoned buildings around him.
He frowned slightly, his eyes full of solemnity.
Without ideas for further improvements, continuing the experiment is just a waste of time.
Zi Sui began to collect the current finished product, and then gnawed on the flesh and blood crystals to ensure that the spiritual energy in his body was at its peak at all times.
While summarizing the current progress.
At present, the speed of his Heyu missile has already surpassed the speed of sound.
Using the knowledge from his previous life, he calculated that the maximum speed of the burst in a short period of time had reached about Mach 50.
You know, in the previous world, the most advanced missiles announced by various countries before his death had a speed of only around Mach 30.
The Zisui He Yu is smaller in size, and the spiritual energy used as a power source is more powerful.
When flying, all you have to do is make sure that He Yu can hold on and not be destroyed.
In this regard, Zi Sui has sufficient confidence in the strength of RC cells.
At a speed of Mach 50, He Yu will be able to directly smash the awakeners of the lower realm without any explosion.
However, facing the awakened ones who can already draw the psychic energy in the air, especially those who can condense psychic shields.
Physical attacks based on speed alone are not enough.
At this time, the explosion caused by the induction of psychic energy became their death warrant.
Zi Sui fully refers to the chain bombs of the human race.
Once the target uses his psychic energy to resist, the explosion will ignite his own psychic energy as well.
Unless the target is missed or the chain reaction caused by He Yu is suppressed in time.
Otherwise, the higher the spiritual energy content in the prey's body, the more explosive its death will be.
But the problem is, the above attacks are all aimed at the body.
Even due to the violent psychic fluctuations caused by the explosion, the prey's soul will also be affected.
But in essence, these do not fully count as attacks on the soul.
At most, it's just a slight damage, not even a fraction of the damage.
If you are facing an individual with a powerful soul, or a species like the elves who are already proficient in soul research.
There is a high probability that the Heyu missile can only kill their bodies, while their souls can escape by chance.
This is quite serious.
Therefore, after much deliberation, Zi Sui decided that the next direction of improvement would be to give the missile soul damage.
Anyway, the damage to the physical body has reached its limit at this stage, so it is better to make it mixed damage to increase the attack power.
But, "For attacks targeting the soul, there aren't many references."
If you start researching from scratch, it might take a long time.
Just when Zi Sui was in distress, He Yu, who had been scattered on the south coast of Kaiyangzhou, was suddenly alarmed.
An awakened being whose realm was close to the heaven landed from the south bank.
Zi Sui devoted a small amount of energy to the He Yu people buried on the seashore.
"Um?"
This aura seems to be a mixture of two races.
They were almost identical to the beastmen he had encountered in the Lingyun Rainforest before, as well as the insects that could control their own kind with soul energy.
"Wait, use souls to control your own kind!"
In other words, those bugs have the experience of controlling soul energy!
It really was effortless!
There was a hint of surprise in Zi Sui's eyes.
A huge area of fog began to surge and then spread towards the coast.
The prey must be trapped before it can react.
In the distance, Hua Yixuan was getting closer and closer to Yin City, completely unaware that he and the insect queen on his body were being targeted.
…
At the same time, in the eastern district of Lantiaozhou Shahai City.
Chi An landed lightly on the roof of the abandoned building opposite the shelter entrance.
He gazed down at the familiar streets nearby, the figures of patrolling soldiers reflected in his bloodshot eyes.
