The purge lasted a week, with the Terminator spraying and disinfecting the entire area before setting it on fire, and so on.

Spencer was unlucky, he was now worse than dead, the expedition he brought was almost wiped out, and none of the survivors survived.

Then he was ordered by Qin Rongshuai to be detained for three months, under the name of "quarantine to observe whether it is contaminated with the virus".

After Qin Rongshuai obtained the Ladder of the Sun, he stayed in Dubai Yaruins for a while to clean up the virus, and then set off to return to Europe.

Leave Spencer and his party to Governas, who will be in charge of arguing with the Spencer family, and he himself will plunge headlong into the laboratory.

During his absence, the scientific research center made an important breakthrough, that is, it cracked the "super soldier" serum in the Marvel world and completed the replication.

Qin Rongshuai was a little surprised to hear the news, and the "Super Soldier" serum was one of his backup options.

When he was in the Marvel world, he took a sample from Dr. Erskine and left it in his personal space, almost forgetting about it.

After coming to this world, he set up a scientific research center and turned out the serum from the corner and handed it over to experts to study and replicate.

However, he is not very interested in the super soldier serum, in the Marvel world, the super soldier serum looks very powerful, and that is only for ordinary people, in fact, the enhanced ability is not ranked among superheroes at all.

PVA fighters who have reached level 10 are stronger than super soldiers, and any one of them can beat anyone who has been injected with serum.

Therefore, Qin Rongshuai pursued more powerful reinforcements to make up for the embarrassment of recruiting more and more soldiers and lacking his glory value.

This reinforcement must allow each soldier to achieve at least the same effect as the main class, that is, the strengthened soldier value must be more than 25 points on average in 3D.

With the large amount of capital investment from Qin Rongshuai and Kevinas, the research progress of the scientific research center is advancing rapidly.

The experts of the scientific research center have successfully extracted the essence from the blood orchid, which can greatly extend the activity and lifespan of cells.

However, neither the "Super Soldier Serum" nor the extract of the Blood Orchid could reach the level of the bloodline of Kovennath, and the gap was extremely obvious.

Qin Rongshuai began to play on the idea of old Kevenas, and spent all day thinking about how to obtain the blood of this undead ancestor and use it to improve his soldiers.

It's a pity that this idea is still unrealistic, not to mention that Alexander Kevinas is only one person, and there is not much blood even if it is drained, even if the energy source is constantly obtained from his blood, there is no way to directly use it on the body of the system to recruit soldiers.

In the end, he put his hope on obtaining the Ladder to the Sun.

After several weeks of hard work, the experts of the scientific research center finally isolated the strain of "Progenitor virus" on the solar ladder and began to cultivate.

However, the research got stuck at this point.

The Ancestral Virus was so domineering that all the animals injected with the virus were alienated, either dying on the spot or becoming crazy monsters.

After repeated experiments, the experts of the scientific research center agreed that this virus is too terrible, and it is better to destroy it directly, except for bringing disaster to mankind, there is no benefit.

If Qin Rongshuai hadn't known about the Ancestral Virus, he might have been persuaded by these experts to give up.

However, he also realized that the progenitor virus was very flawed, and there was only a chance of strengthening it when injected into the human body, and most of them would become monsters, and this chance was extremely low.

Therefore, it cannot be injected directly, and the destructiveness of the progenitor virus must be reduced.

Qin Rongshuai once again focused on Alexander Kevinas, and after obtaining a blood sample from him again, he put the Progenitor virus in it.

This time the Ancestral Virus mutated, and it began to stabilize, changing from a rampaging beast to a docile pet.

Qin Rongshuai had to sigh that Kevenas's genetic bloodline was really the most powerful bloodline in the world, it could perfectly fuse various viruses and transform them into viruses that were beneficial to the human body.

After preparing the modified progenitor virus, Qin Rongshuai couldn't wait to start human experiments.

After screening and rigorous preparation, the virus was injected into the volunteers' bodies, and soon the virus began to modify the volunteers' bodies.

The process was very violent and rapid, and we could see that the muscles of the volunteers' bodies were rapidly bulging and their body shapes were changing.

But after only a minute or two, the volunteer's body began to convulse, and then he fell unconscious, and by the time the experts rushed into the isolation room, the volunteer was bleeding to death.

Qin Rongshuai, who witnessed the whole process, sighed, it still looked like there was something wrong.

However, the results of the subsequent autopsy made everyone stunned, and the volunteers did not die of the virus, but of organ failure.

It turned out that because the process of strengthening the human body was too rapid and violent, the nutrients stored in the body could not meet the requirements, which caused the death of the volunteers.

The discovery made the experts at the research center extremely excited, which showed that what they had developed was not fatally problematic, but that the experimental design was wrong.

After learning the lesson, the experts selected volunteers to let them eat a large amount of nutrients before starting the experiment, and at the same time, when the virus was injected, a large number of nutrient solutions were injected at the same time.

After such a toss-up, the volunteers finally survived the strengthening stage and successfully completed the strengthening mutation.

The volunteer's body seemed to be stretched and magnified, his muscles bulged out, full of explosive power, his body was well-proportioned, and his eyes were shining.

After Qin Rongshuai saw this scene, he was extremely excited and excited, and immediately tested various data on the experimental subjects.

Strength, endurance, bounce, flexibility, balance, reaction speed, and even vision and hearing were all comprehensively enhanced, and preliminary measurements showed that the strengthened volunteers were more than six times more physically fit than the athletes.

"It's done!"

Qin Rongshuai clenched his fists very much, his plan was preliminarily completed.

Stimulated by the experimental results, the experts of the scientific research center began to frantically tackle key problems again, using the ingredients isolated from the super soldier serum and the blood orchid, and successively injected them into the virus.

Once again, the perfect bloodline of Kovinus played a key role, fusing it to mutate and evolve the virus again, named the "Super Enhanced Type 1" serum.

Qin Rongshuai directly summoned a lv.1 system soldier from the recruitment list, and then injected the serum into the system soldier.

Soon, it was time to witness the miracle.

The system soldier's body quickly digested the serum, and almost in the blink of an eye, it was strengthened.
