The expansion of underground people made the construction of strongholds very simple. Although it was difficult for them to understand that these aliens dared to build houses in broad daylight, they still gave Duda everything he needed.

When they were with them, Duda felt that he had been purified and had no idea of ​​trading at all, so he could only take what he needed. For this reason, Duda sent them a large amount of fresh vegetables. This made Karami feel very embarrassed and gratefully brought her own exclusive hangar stationed on the moon base to provide sufficient brain power for Duda's scientific system construction.

For Pegdragons, thermonuclear energy is a dangerous and wasteful energy, and they prefer to use Gorou multi-mineral and geothermal energy.

"We once had an idea, just like using Geliuduomine to wrap the stars, so that the star energy can be converted into energy and transmitted back to the maximum extent." Karami sat on the podium and said to the scientists below. Zhang Tianyu and the others could basically understand what she meant through the translator.

"We call the one you said Dyson Ball," said Zhang Tianyu, "We have considered it too."

Dyson's ball was a theory proposed by Freeman Dyson, who had been Einstein's assistant, in 1960. He envisioned using a ball with a diameter of 200 million kilometers to wrap stars as a source of power.

"Didn't you do it?" Karami asked curiously.

"This is just an idea, and it is not technically successful." Zhang Tianyu said helplessly, "At that time, we had just landed in space and couldn't even get close to the stars."

"Well, our problem is the same as you." Karami said. "We are about twenty years away from the nearest alien star, but it turns out that we encountered the Zerg War, which is really frustrating."

Zhang Tianyu thought to himself: We are still a little far from the star we live in...

"We are so stupid. We can't fly the star system yet, so we started to study it, uh, Dyson's ball?" Karami felt a little inferior in front of Earth scientists. She mistakenly thought that the technology of Earthlings was much higher than that of them. So many difficult problems were simply a piece of cake when putting them in front of Earthlings.

Little do they know that these scientists are just good at playing platter games.

"Don't say that, the development of science has never been produced by lined up." Zhang Tianyu comforted. He suddenly remembered the recent war situation and asked, "You have even developed Dyson's balls. So isn't it easy to use geothermal energy?"

"Of course, 45% of our current energy use is geothermal energy." Karami became more and more ashamed. This number was counted by Earthling scientists.

"So, why not build a large surface city?" Zhang Tianyu stood up, "Use your shield technology to cover the entire city! Then directly extract geothermal energy to support the shield from the volcano! The geothermal energy replenishment rate is extremely high, and then use Geliuduomines to supplement it. Isn't this making the Zerg unable to break through?"

There is such a virtual city, which is enough to cover small strongholds and attract a large number of Zerg combat power.

"Our shield technology is completely incomparable to the ancients." Karami said, "It cannot automatically sense the changes in the surrounding energy. It can only be turned on manually. The energy conversion rate is low, the energy consumption is huge, and it is easy to be broken. The Iron Fortress almost fell because the large shield could not support it."

"There were twelve dragon insects at that time, but now there are only three." Zhang Tianyu stood up excitedly. "I think this method can be tried! Even if it is broken, it will only be a loss of some building materials." Karami looked at the genius scientist with admiration, but her mind was so chaotic that she could not clarify the logical relationship between the front and the back.

Zhang Tianyu's idea certainly received support from Duda, but only spiritual support.

"Now everyone is concentrating on breaking through the individual shield technology. It would be a waste of resources to build such a large city shield." Duda said. "And we don't need big cities to attract firepower. Anyway, in two months, will the hydrogen bomb be created?"

"It's better to have it than not. For example, the Kada stronghold you want to build, with multiple covers, so that people can retreat calmly?" Zhang Tianyu insisted.

Duda thought for a while and said, "Then let's start with the stronghold first. We will continue to hunt north. For specific materials and funds, please ask Tianwen."

Only then did Zhang Tianyu put down his communicator and turned around and made a gesture of ok to Karami.

Duda ended the conversation with Zhang Tianyu, looked at the people around him, and said, "Stay going."

The mechanical roaming bird is somewhat like an ostrich, but the beautification design on its head is more like a duck. This kind of transportation is most suitable for a natural environment without a road, and it can be said that climbing a mountain and going downhill is like walking on flat ground. The group of people rode the roaming birds for three days and harvested nearly one ton of tank bugs.

The crew captured many exquisite pictures, and even spectacular scenes of Huo Jia and Feihu fighting against a tank bug. The two soldiers used cold weapons almost art, which made the onlookers forget that they were in war now.

"If everyone uses cold weapons, the military will suffer a lot." Bai Ling joked.

"They are not losing money," Duda said lightly, "Everyone uses cold weapons, and there will be more qualified soldiers, and after recruitment, they can greatly improve their own strength."

No matter when, the military will always be the most powerful armed force. Because they control resources, they can attract more powerful forces to move closer to it. Nowadays, many well-known hunters have been invited and are very popular in the army and the land warfare companies.

If it weren't for the spiritual ownership of the Nosippi regiment, the army wouldn't have let them go.

"We have almost finished taking pictures. It seems that the little dwarf is indeed an adventurer's paradise." Although Bai Ling did not really encounter any danger, she still experienced the feeling of living in fear. Every day she wakes up from the tent, she feels regretful of leaving her dream. And at night, she is worried that she won't see the sun tomorrow.

Duda thought to himself: I couldn't bear it after only three days of coming out. The longest record of an excellent hunter is to hunt outside for two months! It was just replenishing supplies and trading at the stronghold, and never returned to the city.

This planet also has no satellites, so there is no yellow-red angle and no distinct four seasons. In this continental plate where locals mainly engage in, it is basically in the spring climate, which is refreshing and pleasant. After experiencing the cold winter in the Arctic, Duda likes the scenery and temperature of this area very much, and even feels reluctant to go back.

Just as he was considering whether to bring Tao Jiu out together, the communicator sent an emergency call signal.

"Boss, there is a cluster of fifty tank bugs rushing towards you, a distance of fifty kilometers. At their speed, you can catch them in just one hour!" Song Yun said.

"Received, you can land and pick up the crew first." Duda said.

"clear."

Although the crew had only two photography and one host, the three of them were the ones who were the ones in the team. Because of them, the speed of the mechanical bird could only be maintained at 30 kilometers per hour. If it was faster, a sharp female would scream, as if she wanted to attract all the insects around her.

Song Yun took them on the Explorer and took the meat away as much as possible. The remaining teams could finally return to the camp by car at a light speed. The maximum speed of the mechanical bird can reach 80 kilometers per hour and has a strong endurance. Even if it is targeted by the tank bug, it can escape calmly.

Song Yun avoided two waves of harassment from floating mosquitoes in the air, raised her position, and still accurately reported the location of the tank insect cluster.

"Is it because we are too efficient in hunting? These guys seem to have bitten us!" Duda kept changing directions and found that the tank bugs were also changing directions.

"Kill them!" Huo Jia roared.

"Only kill them, otherwise they will follow us to the camp." Feihu also agreed with Huo Jia's opinion. If that was indeed an opinion.

"When I came here, there was a canyon, go there to ambush them." Duda said, "Save ammunition, boys, put it in and fight!"

"Oh!" The cavalry finally waited for the powerful enemy and cheered.

Duda took the lead, and Huo Jia quickly caught up. He looked at Huo Jia's maglev motorcycle from the corner of his eyes, and suddenly felt envious.

——This is what a man rides! Is it cute while riding a fool?

Duda thought to himself.

"Boss, there are four hunting teams around, with a total of 110 people. Should I call for help?" Song Yun contacted the distribution center and sought orders from Duda.

"We can tell us to divide the prey evenly and save it by calling for help." Duda said, "It's not that we can't eat it."

"It's fifty... it's better to be careful." Song Yun still sent a helping signal, indicating the coordinates.

Four hunting teams responded one after another, the fastest one could arrive within an hour, and the slowest one would only take two hours.

Duda and his group found the ambush position, arranged anti-infantry mines, and divided them into two teams. One team was responsible for long-range strikes on the key points of tank bugs, that is, their necks. If they were qualified snipers, they could even shoot one shot at a distance of 800. The second team was Duda, Feihu and Huo Jia, and the three were responsible for dealing with the bugs that broke through the fire blockade line.

The three of them are veteran insect killers and can fight against the existence of tank bugs alone. If the three of them cooperate, they can kill one in ten seconds on average.

Fifty tank bugs are just adding weight to the trophy.

"They are here. Get ready!" Duda suddenly felt something was wrong. Although there were indeed fifty tank bugs on the opposite side, it gave him a strange sense of crisis.

Tankworms stopped outside the ambush circle, and they did not rush into the minefield.

This is very unscientific. Facts prove that bugs do not recognize landmines. Since the earliest Earthlings used landmines to deal with tank bugs, they have not learned to avoid them so far. Obviously, they have not recognized the existence of landmines at all.

And today, these big guys who were rushing around were actually standing outside the minefield.

"Damn! They are not tank bugs!" Duda shouted, "Skyman!"!~!
