As a common skill, the cross engraving appears in artificial humans in luxury.

Of course, the artificial human belongs to Helena. Yun Qi's military rank is insufficient and he cannot have a new artificial human.

He made full use of the characteristics of cross-printing and handed over the process of strengthening bullets to artificial people to do it, and he just sat down and enjoyed the fruits.

The way to transform the bullet is very simple. As long as your finger touches the bullet and activates the cross marking skill, two vertical marks will automatically generate on the bullet head.

Moreover, the cross traces are perfectly comparable to mechanical processing, and the process flow line is unique and has no impact on the range and trajectory of the bullet.

This is where the cross engraving is perfectly better than the manual carving of marks on the bullet.

Of course, if you are not in your own hands, the quantity cannot be guaranteed.

In addition, Yun Qi also used the attempt to strengthen the bullet on Barrett.

If Barrett could also use the bullets engraved in cross, with Barrett's penetration, it would be a killing weapon in seconds.

But Barrett's bullets are automatically generated and cannot be directly removed and modified like other bullets.

Just when Helena and Tiefeng thought they wanted to give up this unrealistic idea, Yun Qi found a new breakthrough in a wild way.

He took great courage to remove Barrett.

Of course, he dared not to disassemble deeply. After all, he is not a professional firearms transformer, but he can still disassemble partially.

What he removed was the rear end of the barrel of the bullet that Barrett generated, and then someone made a man touch Barrett's special bullet with his fingers. Then, the special bullet was accompanied by the traces of cross-prints.

Barrett's power was cleverly enhanced in Yun Qi's hands again, but the problems that followed were also very significant. At least Yun Qi had to be cautious when using Barrett's first shot, and there was only one bullet engraved in the cross.

Moreover, because Helena's heraldry has not yet advanced to the level of the Human King's Emblem, it is impossible to store artificial humans, making this Barrett transformed bullet more precious.

"But how do you plan to repair this?" Tiefeng looked at the pile of complex parts on the ground. Because they were forcibly disassembled, many of the parts were deformed.

For Barrett's anti-equipment sniper rifle with complex structures, there is one feature: it is easy to disassemble and difficult to assemble!

Yun Qi smiled and said nothing, but just placed a bunch of small parts near Barrett, and then pressed his hands on the gun and small parts.

A gorgeous alchemy array emerged, emitting a dazzling light in his eyes.

Then Tiefeng found that Barrett was intact.

This is the wonderful effect of level 2 alchemy skills - the restoration.

This ability that was initially forgotten played an unexpected role under Yun Qi's wonderful use.

Time passed by minute by minute, and it was soon time to enter the mission world.

Unlike the initial space, the mission world of killing the city development is no longer single.

In front of a special portal, the world name of the mission that is open to the public is deliberately marked.

Today, three mission worlds are opened, namely "Spartan 300 Warriors", "World War" and "The Promise".

"How is it? Which mission world are you planning to enter?" Helena asked.

Yun Qi and the other three have seen the original works of these three blockbusters, and they are familiar to you.

The disadvantages of the main god giving multiple choices are reflected here, and more choices make people stand on both sides of the head.

Yun Qi's choice is very simple. Just wait patiently to see how many people are entering these mission worlds, or who are there.

Although this is time-consuming, it is a good idea to calculate when there is insufficient intelligence collection.

The three of them found a relatively hidden place and observed it quietly.

It was soon discovered that there were very few people entering the costume drama "The Promise" produced in China, which was probably related to its limited popularity abroad.

"World War" has entered the most people, and "Spartan 300 Warriors" is second.

Helena said: "In my opinion, World War is a science fiction world, so there is no need to worry about the damage of the system's weakening of gun weapons."

Yun Qi nodded. In the ninja world, he was also fed up with the weakening of the laws of space. Barrett, who was originally a killer weapon, played a role to be minimized.

"Okay, let's..." Just as Yun Qi made a decision, suddenly, a familiar figure flashed past Yun Qi's eyes, and then turned into the mission space gate not far away and disappeared.

"Why is it him!" Yun Qi frowned.

"What's wrong?" Helena said with concern.

"It's nothing. I met an old acquaintance. Helena, Tiefeng, I think my plan needs to be slightly adjusted this time..."

One minute later, the three of them stepped into the portal.

[No. a21379 enters the killing space "Spartan 300 Warriors".]

【Task Mode: Not Determined】

【Task Difficulty: Not Determined】

[Plot introduction: In 480 BC, the Persian king Xerxes I led an army of 300,000 (known as one million people), more than a thousand warships, and launched a large-scale attack on Greece. He went south to approach the Demobilis Pass. The arrogant Xerxes I also sent letters of persuasion to the Greek city-states, hoping that the small states would surrender without fighting. This naturally also included the city of Sparta. In order to resist the powerful enemy, the brave Sparta king Leonidas personally led about 7,000 Greek coalition forces gathered from all over the place, and took the lead in rushing to the hot spring pass, guarding the dangerous pass, and facing the massive Persian army's main force.

On the other hand, the powerful maritime troops of Persian Navy, commander Artemisia, approached Athens on the other side of the Aegean Sea. At a dangerous moment, the Greek hero Temistokles stood up again and fought with the Greek warriors in order to defend their freedom, Artemisia, who was flowing with the blood of revenge in his body. They spit out clouds and mists, and the waves were surging. The most cruel killing was carried out in the distant era.]

...

The strange plot introduction is called Spartan 300 Warriors. Judging from the content, it combines "Spartan 300 Warriors" (the first part) and "300 Warriors: Rise of the Empire" (the second part).

But when you think about it carefully, although the playback intervals between the two movies are five years apart, the plot takes place at the same time, both are classic battles in the Second Persian War, which determines the fate of the Persia and the Greek Federation in the future.

Therefore, it is within a reasonable range to combine two parts into one.

Seeing the words "The mode is not determined and the task is not determined", Yun Qi thought to himself: Could it be that the main god wants to play some new tricks?

Sure enough, the new task prompt was quickly connected.

[No. a21379, you and your teammates have just entered from the initial space and have been conducting the mission of killing the city for the first time. You and your teammates have not yet activated the official identity of the Killer.]

[Note: The Killer is an advanced title for the Reincarnator and has more powerful abilities than the Reincarnator.]

[Note: If the mission fails, you can also choose to continue to accept the related tasks of the Killer in the future mission world.]

【Are you and your teammates willing to accept the official mission of the Killer?】
