.Wilan Company South America Research Branch, on the laboratory analyzer table, there are: retractable double-headed spears with plasma launchers, razors, disc-shaped darts with telescopic serrated teeth, wrist cannons and other weapons obtained from the corpses of the Iron Warriors. Several researchers kept observing and analyzing through computers. Carlson looked at the monitor in the conference room and said: "Just from these weapons and that flight ship, these biological weapons and space navigation technology are significantly ahead of us. This creature is really strange. It has already revealed space navigation, laser weapons and stealth technology, but it seems that it retains ancient customs, and the infiltration methods and tactics are extremely primitive, and it is still mainly used for close combat with cold weapons."

"How have those weapons been studied? When can we independently produce all equipment so that our soldiers can also simulate the tactics of those creatures?" Lin Feng asked.

"The alloy composition of Cold War weapons has been successfully analyzed. We can produce these weapons at any time. Our technology can also do it, and it can even be better. It has alloy helmets that receive multiple spectrums and use various rays to observe targets. Now it can only be infrared and blue rays. Others should not be able to obtain complete helmets and cannot be analyzed in detail. The same is true for stealth functions. Only by obtaining intact equipment can it be studied. As for the ion emitters in the spear, although our current technology can be used to install it into the retractable spear, the internal energy can only provide 3, and the power is insufficient."

Lin Feng rubbed his frown and thought about the mixed news. Suddenly, the voice of the main god sounded in his mind: "The side mission Iron Blood Fortress is coming and opened. Survive under the attack of Iron Blood Fortress for 7 days. After completion, each person will receive a reward point of 1ooo. During this period, he cannot leave the South American research area and cannot return to the main god space. Kill an ordinary Iron Blood Warrior 5ooo reward point, kill an elite Iron Blood Warrior 9o reward point, destroy the Iron Blood Flyer 1ooo reward point, a D-level side plot, kill an Iron Blood Elder 12o reward point C-level side plot, and destroy the Iron Blood Fortress 5ooo reward point B-level side plot."

"Haha, it's finally started, Carlson, the implementation of the δ plan begins." Lin Feng said

"What! Now... I know." Although I was a little confused about why the δ plan was suddenly activated, Carlson, who had suffered, was just stunned and immediately went down to execute the plan.

Chu Xuan pushed the door open and said, "Although we can easily resist the small number of iron-blooded warriors and the flying ships with the Vilan Company, do you think this can resist the huge iron-blooded fortress? The large number of elite iron-blooded warriors may be fine to delay for 7 days with their bases, but will such a huge fortress have no large attack weapons? Even if you have any arrangements, it is probably impossible to complete the Iron-blooded attack before."

Just when Lin Feng was trying to say something, Northrend in white walked in as usual. "Reported, the radar suddenly showed a giant spacecraft approaching the outside of the base. The warning message we went there was no response. The air defense weapons we fired were all intercepted. Please transfer quickly. Judging from the current situation, we cannot resist for a long time."

"Okay, go out, I'll make arrangements freely, and continue to report if there is any situation." After knocking Northrend away, Lin Feng leaned back and buried his body in the large black leather sand behind him. He closed his eyes and stopped moving. Not long after, Zhan Lan, Erona, at midnight, the madmen walked in one after another. Although everyone was staring at him, Lin Feng just lay leisurely on the sand and closed his eyes to rest. After a while of silence, Zhan Lan couldn't help but speak: "Didn't we say that we can return at any time as long as we kill the aliens, what should we do now?"

Lin Feng opened his eyes and didn't speak, but just stared at Zhan Lan. She felt uncomfortable all over and Nana shrank back.

"Report, the giant spacecraft appeared in front of the base instantly, and the defense system had completely collapsed. Areas A to B-7 have completely fallen. Please evacuate quickly," said a scarred soldier.

Lin Feng and his men who had just arrived at the ground through the core passage had just walked out of the passage and were dark on the ground. The giant fortress that covered the sky and the sun completely blocked the vision of Lin Feng and others. A green light column shot towards the ground from the bottom of the fortress, and a loud "boom" sounded loudly, and the violent explosion spread out with the rolling smoke and dust.

A thick dark red mist instantly condensed around Lin Feng, and a small barrier was traveling. Arona's eyes were blue. She took out the white light of dusk to wrap herself. The strong light completely covered her body. Gradually, she couldn't see clearly. Zhan Lan took out two gloves and quickly patted the ground. Steel walls completely covered her in a semicircular shape. The madman squatted on the ground, protected her head with both hands, hid in a cover body in a ruin at midnight, dragged an alloy plate to cover her body. Chu Xuan pushed his glasses, without any defense measures, and walked forward slowly.

Not long after Lin Feng and others took the defensive measures, a violent explosion enveloped everyone, and even the earth was shaken. After the explosion stopped, the entire radius of 2 kilometers of the institute was completely turned into ruins. Arona squatted on the ground, and after a while, she "sprayed" a mouthful of blood. Although Zhan Lan's body was a little damaged under the completely broken steel wall, she survived. The madman's skin was completely burnt. From each wound, you can even see the general outline of the bones in his body. However, from his frequent twitching, it can be seen that he is still alive. The cover that was hiding at zero o'clock completely disappeared. Chu Xuan, this character who is very intelligent and close to the demon, had no resistance at the moment when the light column exploded.

The iron-blooded fortress will only arrive after the earth has delayed for a long time, and it is necessary to have certain strength to resist the attackers in the previous rounds. Such characters are likely to gain great momentum on earth. In order to avoid the Iron-blooded Fortress being destroyed by large strategic weapons at the moment of arrival, the fortress will definitely carry out unavoidable coverage attacks. Although the Research Center of the S-25 Branch of Weilan Company was under the control of Chu Xuan, he also destroyed all the alien primordials in the research center in advance, leaving only derivatives and some cell embryos, but in order to ensure the smooth plan, Lin Feng must have hidden aliens in secret, which is uncountable and cannot be avoided. Those who are not strong enough will die.

Faced with the heavy casualties of Lin Feng and others, the Iron Blood Warriors kept coming out of the landed Iron Blood Fortress. Now, the only combat-capable Lin Feng, who has the power, will not have any chance at all when facing such a number of Iron Blood Warriors. The only chance is to wait until the δ plan is successfully implemented.

Facing a large number of iron-blooded warriors, Lin Feng slowly walked forward, gestured with a kiss on his throat with his right hand, and pointed his hideous claws at the Iron-blooded warrior. The elder in the cloak, from the challenge of "Alien vs. Iron-blooded warrior, took off his armor and equipment to fight, it can be seen that the creature Iron-blooded has a knightly style in ancient times and is extremely proud. As an elder, he must be even more so. He could not escape the challenge in front of the warriors. Sure enough, the elder took out the main spear, and the short two-headed spear "rubbed" into two tridents that were 2 meters long, jumped up, and one attacked Lin Feng like a gust of wind.

Lin Feng condensed a thick purple mist on his right hand and faced the spear. Although the Iron Blood Elder was only over 2 meters tall and was extremely thin in front of Lin Feng's eyes, it was nothing different from the elder who had sneaked into the attack before. Although he grabbed the spear, the extremely strong force caused Lin Feng to retreat two parts, and a trace of scar appeared on his strong right claw.
