For seven days in a row, Li Yuan stayed in his room for seven days! In addition to eating, sleeping, and cultivating, he downloads all kinds of high-tech materials on the computer! Among them, there are several technologies that make Li Yuan the most interested, one is the injection technology of electrical plasma jet mentioned earlier, this technology has been rotten on the street, that is, there is a huge amount of content, covering a wide range of application fields, and it has been downloaded for a long time; One is the manufacturing technology of the "Nimitz-class" nuclear-powered aircraft carrier, look at other people's space-class warships, this technology has become a child's toy in the federal era, and even in some online games, real data is directly used to design and produce; The last one is the full use of solar energy technology, the reason why the Federation of the Earth can achieve rapid development is inseparable from the unlocking of energy, after the full application of solar energy technology, many ideas have been realized, including the design of space warships.

The content of these three technologies is extremely huge, and even if the network on the battleship is already very fast, it still took Li Yuan nearly 4 days. In the remaining three days, he found a lot of scattered small inventions, but there were many things he didn't understand, so he could only download them first, go back and take them back and study them slowly.

"Hey! Far! We're leaving tomorrow, let's go, let's go have a drink! Duncan never gave up on Li Yuan, and came over every night to invite Li Yuan, although Li Yuan refused.

But this time Li Yuan gave Duncan a lot of face, and he also planned to go out for a spin, after all, he still had 250 in his pocket.

In fact, the allowance of the federal soldiers is still very high, but it was pitted by the system, and Li Yuan, who was only 250, became a poor egg.

Eating and drinking in the fleet are free, and the specially set up self-service shop has a wide variety of products.

Li Yuan glanced at it a few times, and spent 100 to buy a remote-controlled hovercar for children to play with, the principle is exactly the same as the big one they drive, but it is a miniature version, specially for these soldiers to buy to coax children, the army special!

In addition, I also spent 150 to buy a small plasma shield, which can protect the combat area of three people, and effectively defend against a shuttle fire equivalent to a large-caliber machine gun, that is, the bombardment of nearly 100 bullets, or the impact of a heavy truck, but because this thing is a one-time consumable, and it is not practical in the war of people and insects, once you are close to the insects, even if there are a hundred, it is useless, because you can't shoot back yourself, you can only watch yourself being swallowed up by the sea of insects!

After buying the two, Li Yuan lost the interest of continuing to wander around, so it was better to go back and download a few more high-tech courses.

Li Yuan has downloaded a full 7 storage terminals, and even the individual computer is full, you must know that these storage terminals are not simple mobile hard disks, in the technologically advanced federation, a storage terminal is equivalent to 10 DB, that is, 1024 to the 8th power of TB multiplied by ten!

And the individual soldier computer also has 8DB of storage space, Li Yuan didn't plan to leave it in the dormitory obediently, and it will definitely appear in Li Yuan's space when he leaves tomorrow.

After a night of silence, Li Yuan knew that he would not stay in this world for too long, and he didn't want to make trouble, so he simply refused other activities and rested for a night.

Early the next morning, the infantry in the entire battleship was busy, receiving armor, ammunition, guns, all of them were well-trained, without a trace of panic, and morale was extremely high.

The new generation of armor has a big difference, not only the protection is 30% higher than the previous generation of armor, you can take more travel spiders, but also a lot lighter, and the upper body is equipped with exoskeleton armor, which means that Li Yuan can carry more ammunition supplies, when shooting, the recoil is also greatly reduced, and the physical consumption is reduced by more than fifty percent!

The tough guy unit has been replenished once, but it is true that most of them are new recruits, all of them are children, and their combat effectiveness is worrying. As the commander, Lazak was naturally full of complaints, but he could only choose to accept it. In the space battleship busy doing carpet bombing, doing the final lecture, and at the same time asking the more than 50 veteran team members in his hands to take care of them more, no surprise this will be the last battle, he does not want these children to die on this strange planet.

It didn't take long for the airborne ship to kick in, spewing blue flames and sending the tough guy troops to the planet where the final battle would take place. On the planet that had just been assembled and was already devastated, a series of purple-white plasma suddenly shot out, pointing directly at the warship forces in the universe!

Everyone was stunned to see the transport ship that had been detonated by the plasma tail flame, if it had been launched when they landed, everyone would have to burp and catch a cold. It didn't take long for bursts of cries for help and roars from the communicator, and silent salute flowers bloomed in the sky, representing the destruction of space warships one after another!

In the silent firelight, a number of meteor-like escape pods broke through the atmosphere and crashed into the earth, the lucky ones could land directly near the ground troops under the operation of the survivors, and the unlucky ones disintegrated into ashes directly in the air, and the medium luck, such as Rico's ex-girlfriend Carmen and Sundel, who cuckolded him, directly crashed through the mountain and fell into the interior of the Zerg cave.

Just kidding, Rico's flowery radish couldn't help it immediately, according to the plot, he insisted on leaving all the troops behind and going to Carmen, this time it was not the commander of the unit, but he was going to rush up single-handedly, without any scruples about the feelings of Deeds, who was still alive.

However, jealousy is jealousy, Deeds still married a chicken and a dog and followed behind Rico, and Duncan looked at Li Yuan directly, with the intention of breaking off friendship with you if you don't go.

Li Yuan was angry in his heart, I don't know anything else, this Nima is destined to die for a lifetime, and he can't harvest many killing points, how can he stay with the big army and harvest safely.

It was Razak who stepped forward and interrupted the crowd, "Carmen and Sandel once drove a spaceship to save our tough guy troops, we can't die without helping." The space of the Zerg cave is limited, and there are too many people to show it, Li Yuan, I will arrange six more people for you, ten of you are the chief officer of the operation, and Ruike is the deputy! Rico! You've lost your cool, Deeds, give me a good look at him! ”

Li Yuan also knew that he couldn't refuse when he heard it, this Razak had already spoken, and there was no point in talking nonsense, so he directly received the order from Lazak, "Sir, can you give me a few nuclear bombs?" That stuff works! ”

Razak was also generous, and directly took a nuclear bomb launcher and handed it to Li Yuan, which was also equipped with three miniature nuclear bomb warheads.

After the preparation, Li Yuan led everyone into the winding and complex wormhole, led by Ruike, who let him be able to sense Carl's location by the protagonist's aura.

"Hmph, big carrot, look back and see how you ended up with Deeds!" Li Yuan followed behind Rui Ke, thinking viciously.

After nearly two kilometers deep into the cave, "there are bugs in the back!" Yadel, the soldier in charge of the rearguard, shouted a warning while shooting!

Li Yuan only carried a rifle in his arms, but he and Duncan each carried a spare one on their backs. He sliced a side cloth away, and then fired at the rear, "Duncan, Yadel, Udir, and my Highness, Ricko!" Hurry up and find Carl! We must rendezvous with the big forces as soon as possible! ”

Thanks to the passage of the Zerg, which is only the size of a truck, Li Yuan and the four of them shoot alternately behind it, but they can also fight and retreat at the same time. But of course, Li Yuan is full of firepower, crazy harvesting and killing points, and no matter how hard he works, he can reach 100,000 points.

Advancing forward for more than two hundred meters, Li Yuan was fighting right here, and Ruike and they were also attacked by giant spiders in front, forming a two-sided attack for a while.

Li Yuan fought and retreated backwards, and suddenly hit a person in the back, startled, and quickly looked back, but it was Deeds standing in place and shooting forward, "Damn, Rico!" Hurry up and move forward! Is the guy in your hand a burning stick? "You can't blame Li Yuan for being angry, once this activity space is compressed, the shooting distance will be suppressed, and it will be troublesome if you want to move.

"Deeds! You come to my place! Li Yuan emptied the magazine, turned around and made adjustments, and went to the front of the team to find a way to open the way!

When they came to Rico's side, they resisted the attacks of many giant spiders, but the vitality of giant spiders is too strong, as long as they are not completely killed, even if they are paralyzed on the ground, they will suddenly bounce up and bite you anytime and anywhere, Rico is also very anxious, he doesn't want to risk other people's lives.

Li Yuan knew what the situation was at a glance, the insects on the ground were injured and not dead, they were all killing points, one was worth 500,000 yuan, it was all money!

Without saying a word, Li Yuan stepped forward with a rifle, each of which fired more than a dozen bullets into the head, and the rhythm of grabbing people's heads frantically. And Ruike and they continued to output behind Li Yuan, no longer trying to kill the giant spider, just scrap it, Li Yuan specially stepped forward to be responsible for replenishing the gun!

Duncan and the four of them only need to defeat the giant spider in the back and cause a traffic jam to complete the mission, and the safety of the team is guaranteed.

"It's right ahead! See! The passage through which the survival pod is smashed! Ruike suddenly pointed to a gravel passage in front of him and shouted, Li Yuan raised his eyes and saw that the passage was just the size of a taxi, people could turn around, the giant spider was enough to choke, as long as a few were killed, the hole could be blocked, and if it blew up, it could temporarily avoid the siege, and immediately shouted, "Hurry!" Assemble at the mouth of the passage! All enter the passage! ”

Li Yuan stepped forward and stood at the entrance of the passage in a few steps, took off another rifle on his back, and shouted "Duncan!" ”

Duncan also took off the two rifles and loaded them on their magazines, and responded, "Understood! Then he stood behind Li Yuan and continued to act as a secondary shooter!
