The fire burned all night, and in order to fully burn the corpses, the air tank kept taking off and dropping incendiary bombs on the two corpse piles to refuel.

The pungent smell of burnt corpses filled the vicinity of the burning corpses, and the thought of the source of the burnt smell was disgusting, and the space soldiers retreated far away in armored vehicles.

Bai Qi gave the cards he had collected in the cave to Barian and asked him to distribute them.

This time, Bai Qi and they assassinated a total of six plasma worms, but they were not the best results, the best results were the Nine Fortress team led by the knight, they killed a total of eight plasma worms.

According to the news that Amos heard, the No. 1 Fortress team led by the Freedom Alliance assassinated five plasma worms and barely completed the task, and the No. 3 Fortress team led by the Sword Cultivator and the Ice Bear had the same score as Bai Qi and them, which was six.

The six plasma worms left Bai Qi with a light black card and two dark blue cards.

Of course, this is not the most important, the most important wealth left to them by the plasma worm is a full ten plasma stones.

Plasma worms have three heads, and each head has the potential to dig out plasma stones, and six plasma worms, eighteen heads, have dug out ten plasma stones, which is not a low ratio.

The only light black card was left by the plasma worm that had been charged and almost killed Bai Qi, while the two dark blue cards were left by the plasma worm that had not been charged, which was obviously related.

In addition to the cards left by the plasma worms, they also killed a lot of guards in the caves, such as the Plasma Worms, the Knife Bugs and the Tank Bugs, as well as the sporadic Zerg encountered in the caves, and obtained a total of four dark blue cards. More than thirty light blue cards.

Of course, the black card belongs to Bai Qi, and no one has any objection to this. Next, Barian was also very fair in the distribution of blue and light blue cards, and everyone had no opinion.

Early the next morning. The rested human army set off again, and their target was not the miners' city behind them, or other base fortresses, but the Zerg lair in the north, which was part of Bai Qi's battle plan.

Before the human army came to the northern mountains, they did not attack immediately, but set up a defensive formation ten kilometers in front of the mountain.

At the same time, the military brought prospecting experts and a large number of advanced prospecting instruments from the city of miners to carry out a thorough geological reconnaissance of this mountainous area.

Although due to the fact that for thousands of years no foreign enemies have been encountered. The development of military science and technology of the Earth Federation is somewhat deformed, but in terms of civilian technology such as prospecting, the Earth Federation is not ambiguous at all, and after sacrificing a large number of prospecting reconnaissance balls, the specific geological conditions of this mountain range are completely displayed in front of mankind.

The Zerg's nest is not in the dense layer of caves in this section of the earth, three or four hundred meters above the surface, but in a solid rock formation five hundred meters below the surface.

At this depth, even the maximum yield of ground-penetrating nuclear bombs carried by human spaceships cannot penetrate it, not to mention that there is a five-hundred-meter-high mountain erected above the Zerg lair.

At this time, even if humans have completely occupied the surface, they are a little clueless about this turtle shell.

Drilling through the ground cannot penetrate such a thick rock formation.

The maximum yield nuclear weapons carried by the fleet frigates cannot penetrate such deep rock formations.

And even if humans really have the ability to blow up the Zerg mother worm five hundred meters underground. They're not going to do that, either.

Human geneticists have studied the genes of the Zerg, and they have found that the genes of this creature are unusually simple and uniform, as if they were artificial. Without any individual differences, such genes do not allow humans to explore the secrets of the Zerg.

A geneticist once proposed that the genetic secrets of the Zerg must be hidden in the body of the mother. Only by getting the corpse of a female worm can humans crack the genetic secrets of the Zerg. Development of targeted weapons.

Previously, kill a mother-queen. It was almost an impossible task to get its corpse, but today, this opportunity was placed in front of humanity, and of course they did not want to miss it.

The only way to do this is to send someone down.

In the end, Bai Qi's operational proposal was again adopted by the military.

Bai Qi's suggestion is simple, the federal military launches a frontal attack, attracts the main force of the Zerg, and sends special forces, that is, space warriors, to infiltrate and carry out a decapitation operation.

After the strategy was determined, all space soldiers received the challenge mission of their own space.

Challenge Mission "Female Worm Sample": Attract the attention of the Zerg army with the help of the Federation Army's frontal attack, infiltrate the Zerg lair, kill the Zerg mother worm that has descended on the planet, and bring the female worm corpse out to the Federation military.

This challenge was expected by everyone, and to everyone's surprise, the knight immediately called a virtual meeting.

Everyone said a word, and soon agreed on a battle plan.

No one asked Bai Qi's opinion anymore, the mission has progressed to this point, the human race has basically won the victory, if it is not for the rich rewards of this challenge mission, everyone can return to their respective bases and wait for the mission time to end.

Without the threat of total failure in the mission world, naturally no one cared about Bai Qi's opinion.

In fact, according to experience, most of the challenges are difficult to shortcut, at most you can only strive for some favorable conditions, and if you want to win, you have to rely on strength to speak.

The success of Bai Qi's previous strategy has actually won the greatest favorable conditions for this challenging task.

According to the underground topographic map provided by the military, after the military started a war against the hive, the space warriors dived into the ground from the rear of the battlefield and approached the lair of the zerg.

After the space warriors approached the defensive circle of the Zerg lair, the Darkwalker continued to infiltrate, planted bombs in the direction of the Zerg lair's attack by the Federation Army, blew up the cave, cut off the retreat of the Zerg who were fighting with the Federation Army to help the lair, and finally, all the members attacked the Zerg Lair and took down the mother worm.

Although the Tower of Babel does not encourage Space Soldiers to use technological weapons in formal combat, it is not within this scope to use technological weapons to create some favorable battlefield situations.

The plan was simple and effective, and it was quickly approved by all staff.

The federal military also quickly agreed to the battle plan of the space warriors, not only provided them with a large number of miniature nuclear bombs, but also analyzed the geological structure near the hive as quickly as possible, and gave dozens of points to place bombs, as long as the nuclear bombs can be detonated at these dozens of points, it can cause the complete collapse of the porous rock formation, so that the Zerg army entangled with humans cannot return in a short time.

It is inevitable that there will be many dreams at night, and once the plan is finalized, it will be launched immediately. (To be continued......)
