Chapter 5540

Just when Yun Yi was about to collapse, Xiao Mango and Xiao Yining finally successfully shuttled back from the galaxy over there!

"This is the Earth Core Grass, which grows in the lava closest to the center of the earth. It has a strong and strong medicinal property and absorbs super strong light and heat in the lava all year round.

The Zerg are afraid of light and heat, and this medicinal herb can be regarded as a natural enemy for them.

They have no time to exert their super strong regeneration ability and will be destroyed by the medicinal properties of the Earth Core Grass.

The reason why the Empire and the Federation were able to unite the entire interstellar space to wipe out the Zerg hundreds of years ago was because they discovered the Earth Core Grass.

They first found someone to extract the medicinal properties of the Earth Core Grass, sneaked into the M2 planet, which was still the Zerg's mother planet at that time, and put the extracted concentrated Earth Core Grass juice into their drinking water source.

Overnight, most of the Zerg were killed and injured, and then they led the joint army to kill into the M2 planet and killed the Zerg by surprise.

This is why the Zerg was later destroyed and M2 was completely abandoned."

Xiao Mango opened a small box on the table, revealing the small culture dish inside, and introduced it to everyone.

The Zerg has super vitality and regeneration ability, and is extremely aggressive.

Before the discovery of the Earth Core Grass, the Empire and the Federation, including the residents of other planets in the entire interstellar, suffered greatly from it, but they had no way to deal with it.

The Zerg took over many affiliated planets, and the Shadow Clan is the best example.

If the Empire and the Federation do not resist, it will not be long before they will fall into the same fate as the Shadow Clan and become affiliated planets of the Zerg.

This war is just, but the act of secretly giving drugs is indeed shameful.

Therefore, regarding the history of the extermination of the Zerg, the Empire and the Federation, including other participating countries, have no relevant records.

Xiao Mango and Xiao Yining also spent a huge amount of money on this trip, and finally learned about this period of history from the Minister of the Empire's Military Department.

Of course, the minister must have some reservations about the truth of the year. The means used to almost completely exterminate the entire Zerg race are definitely not as simple as secretly giving drugs.

However, their original purpose was not for this history. Getting the news of the Earth Core Grass was the most important thing.

The growth environment of the Earth's Core Grass is extremely harsh, so the number of people who can successfully survive is extremely rare.

Ordinary people and ordinary spacecraft have no way to reach the location near the center of the earth.

Fortunately, the rare resources on the M2 planet are extremely rich. Little Mango has a weapons expert Yuan Fei and the master of the mecha manufacturing master, Master Lasen. Spacecraft and human body wear equipment that can withstand the high temperature of the Earth's Core are quickly manufactured.

But the most difficult part is that after the Earth's Core Grass is picked, the medicinal properties will be lost within 48 hours.

And they need to travel through time and space, and there is too much uncertainty in the middle. No one can be sure that they can get back within 48 hours.

That's why they will delay some time there.

In the end, Master Lasen sold a favor and found a plant expert friend of his to help them a lot and made this culture dish for them.

Yun Yi looked at the small bunch of fiery red Earth's Core Grass in the transparent culture dish, and pursed his thin lips tightly, "So, as long as you extract the liquid from these Earth's Core Grass and give it to your mommy to drink, you can kill the king egg in her body?"
