This is undoubtedly a pastoral time. When people come out of the interstellar gate, it is easy for primitive humans to have a feeling of worship. Under the influence of this kind of worship, it is not difficult to control the behavior of primitive people.

Aolu teaches these primitive human languages, trains them to abide by discipline, and most importantly, they continue to reproduce and prosper.

In just one month, this ethnic group expanded to more than 300 people, accounting for nearly half of the women of the right age. Any woman of the right age became pregnant.

This is an inevitable action for a population that is on the extinction line at any time. Although it has not received medical help from the reincarnationists, the medical knowledge and prior training of the reincarnationists allow them to ensure the health rate of the population, especially the health of pregnant women by maintaining hygiene, collecting herbs, etc.

The reincarnators stayed here for less than two months. Although their lives seemed very peaceful, the reincarnators knew very well that it was impossible for them to remain calm all the time. Staying here might bring misfortune to these people.

Returning to the Serbian, the interstellar journey set sail again. Now there are only seven people left in the huge spacecraft, and they suddenly appear lonely.

Lu Yu, Alice and Sims simply immersed in deconstructing this ancient interstellar exploration spacecraft and tried to digest the technology of ancient civilizations.

Arnold fiddled with the plantation and created a quiet small garden on the Serbian.

Nord, Xiaopang Brother and Chen Tianming occasionally pass through the interstellar gate to take an interstellar exploration journey full of unknowns.

On the 90th day after entering Serb, Serb detected an abnormal signal, and then a fleet appeared at a distance of 9,000 kilometers.

At this time, Nord and others were still exploring interstellarly but still returning. Lu Yu, Alice and Sims were busy working in their own laboratories respectively, and Arnold was building a carefully cultivated bonsai in small scale.

The alarm sounded on the Serbian, and Lu Yu and others rushed to the cockpit of the spacecraft. Arnold didn't even have time to put down his tools, and ran over with scissors in his hand and wearing an apron.

"The space fleet that appeared was approaching us, and the Serbian tried to establish communication with them, but received no reply.

Judging from the other party’s energy reaction, the person who came was not kind!

Serb, be prepared for combat!”

Lu Yu obtained command of the spacecraft and issued an order.

The Serb immediately entered an armed state, and the war-level energy shield was activated externally, and various weapons on the hull began to warm up.

Alice said: "We will have to maneuver. We may temporarily disconnect from the expedition team's star gate. Now we cannot contact them for the time being. We can only leave information and then maneuver. I hope we can come back and pick up the expedition team smoothly."

Lu Yu said: "If you do a triangular leap, you may be able to get rid of the enemy or kill them elsewhere. It will not be too late to pick up Nord and the others," he said.

Sims, is the jump engine ready?"

Sims replied: "There is no problem with the transition engine, but the spacecraft's strongest weapon, the energy cannon, requires a large amount of power. Some of the functions of the Serbian have not been repaired yet, and the energy cannon and the transition engine will affect each other.

Especially within half a minute before and after entering and launching a jump, we will not be able to use the energy cannon, or in other words, we will not be able to enter the jump half a minute after using the energy cannon."

"I understand. We will give priority to maneuvering and will not open fire for the time being!"

"Damn it, the opposite side opened fire!"

The holographic image of the Serbian shows that the enemy fleet has a total of six spacecraft, and the two of the first ones have opened fire on the Serbian.

"This is a tentative attack, and they must be trying to judge our strength.

Don’t play with them, just jump directly, and make the time difference with them."

Lu Yu directly launched the transition program and set the target point near a explored star system one light year away. In addition to taking advantage of the familiar space, he also needs to ensure that Serb has sufficient energy sources, because the power sources equipped by Serb are not suitable for long-term high-intensity combat, and may need to travel through stars to replenish energy at any time.

After the leap is completed, after reaching the new coordinate point, Lu Yu releases the Time Traveler in the warehouse.

"First let the Crossover hide near the planet and attack them in an ambush. We will circle behind the stars and hit the final sniper."

After a period of research, the height of ancient human civilization really surprised Lu Yu and others. Even if Lu Yu had the knowledge of two civilizations, the power system and weapon system built for the Time Traveler were still far from the height of the Serbian.

However, the situation of the enemy's fleet is unknown. The Serbian has undergone a long voyage and some key systems have not been repaired. Lu Yu is unwilling to take risks with the Serbian.

When the Serbian and the Crossman were both ambushed, the enemy fleet also jumped over.

Sims controlled the Crossover in a remote manner. When the enemy fleet was looking for Serb and passing by the planet that Crossover was dodging, the Crossover flew out from the back of the planet, shining light on the inventory of missiles. At the same time, he continued to bombard the enemy fleet with electromagnetic cannons until it was overheated, and then he took advantage of the enemy fleet's failure to react and fled.

The strength of the enemy fleet cannot be underestimated. The Crossover made a fierce operation, and the initial electromagnetic gun attack failed to tear a hole into the enemy fleet's energy shield.

Immediately afterwards, only one-third of the missiles arrived near the fleet under the active defense of the enemy fleet and detonated.

It was a concentrated explosion of nearly 100 million tons of equivalents, but it only tore a hole in the enemy fleet. Two of the spacecraft were affected by some shock waves and slowly retreated behind the fleet, but the entire fleet still maintained its formation and continued to move forward.

At this time, the Serbian's energy cannon was also ready. When the technology reaches a certain height, the principle of the weapon will look a bit simple and crude.

The energy cannon locked in the local fleet. The moment it was launched, Lu Yu and others in the cockpit felt a burst of high pressure.

The Serbian artificial intelligence reminded: "The spacecraft's internal protection structure has defects and cannot completely shield the side effects of energy weapons when launching, please be cautious."

All were launched, and the reminder was useless.

Fortunately, the high pressure passed in an instant, and the four people who stayed on the spacecraft were all tenacious enough.

When they checked the effect of the energy cannon bombardment, they were stunned.

At this time, where is the signal of that fleet in space? Even a planet close to the fleet and the Serbian disappeared.

But Lu Yu and the others didn't have time to review, and the Servi continued to warn: "The energy of the spacecraft reaches the threshold and will enter the charging program."

After entering the charging program, the electronic system of the Serb spacecraft will be temporarily turned off, and artificial intelligence drives the Serb through the stars for energy recharge.

Lu Yu and others could only wait patiently for the charging to complete.

After the charging was completed, everyone was surprised after the previous scene was called up.

In just a moment, Serb's energy cannon wiped out the fleet that had come from badly, and at the same time wiped out all the celestial bodies in the orbit of the energy cannon, including planets, satellites, and meteorites.

The distance to be erased reached one tenth of the light-year, and several galaxies in orbit were hit by undesirable disasters.

Is this strength?

The three of them did not rush back, but instead inspected the entire Serbian system. Some control modules on the Serbian were not repaired, which led to the inability to make accurate predictions when entering the armed state and attacking enemy targets. They could only make full attacks, which caused huge side effects.

However, to fix these loopholes, Lu Yu and others need to continue researching them.

The Serb returns to the coordinates that can connect to the stargate.

Nord, Chen Tianming, and Little Fat Brother returned to the Serbian, but they looked dusty, their protective suits looked old, and after taking off their masks, they were even more unshaven and tired.

"The flow of time on this planet is twenty times faster. Damn...we're spending more than a hundred days on it."

The first thing Nord did was to find Arnold's greenhouse and get some fresh fruits to eat: "The plants on this planet are not what we are used to. Although they can produce the food needed by animals, none of them are suitable for our tastes. During this period, we can only eat canned food to satisfy our hunger, but I'm so hungry."

Chen Tianming said: "The indigenous living organisms on this planet are a kind of flying humanoid creature. At first I thought we were enemies and chased us for a long time.

Although they were in a relatively primitive civilization, they had a relatively good organizational degree. Among the population we first came into contact with, a great female leader led his tribe to fight together.

She was very strategic and beat us to run away, but later an adventure happened, which made us reconcile with them. Even Brother Nord had a relationship with the female leader..."

Nord's old face turned red, but he couldn't stop Chen Tianming and Xiaopang Ge from continuing to gossip, so he could only eat fruit in silence.

Brother Xiaopang has good painting skills, and he just took a look at a flying man. The faces of those flying man look very much like humans, and his body torso is not much different from those of humans, but his limbs are somewhat similar to those of pterosaurs.

"Nord and the leader should have descendants, and when we left, we also discovered that the clan had begun to record this myth in murals and ritual vessels.

If this ethnic group can really develop into a developed civilization in the future, perhaps Nord will become a patriarchal god in the civilization."

After hearing the trio of investigation talked about the interesting things about exploration, Lu Yu showed them the video of the previous firing.

It seems to be just an unintentional daily life, but there is a crisis buried in it.

The Serbian was conducting a long interstellar flight and did not deliberately use any technology to disguise it. It was normal to be coveted by other interstellar civilizations.

Nord decided to stop the inspection so as to give Lu Yu and the others enough time to fix the loopholes in the Serbian.

Lu Yu and others made good progress, and some key modules on the Serbian were repaired.

But life on the Serbian was not dead silent. After more than 120 days of voyage, the interstellar gate on the Serbian was dialed from the outside for the first time.

After the signal is dialed, the first thing that comes is an encrypted message.

However, it is not necessary to decrypt Lu Yu and the others. The artificial intelligence of the Serbian said: "This information is encrypted using some common encryption method that used to be, and the ancient civilization had not yet broken."

"Is this a signal from ancient times, or a signal from other branches of ancient civilizations?"

However, when the signal was decrypted, everyone was shocked when they saw the message of the signal.

"Don't come here!"

What's going on?

The information has no cause and effect, it is just a warning.

"This message also uses the highest level warning signatures of ancient times," Serbia reminded.

This is worthy of fun.

Next, Stargate was dialed again, and Serb asked: "Will the connection request from the same coordinate be made to connect?"

"Connection rejected."

Lu Yudao.

The connection was rejected, but after calming down, everyone became curious because of what just happened.

Curiosity is a terrible thing. After a while of silence, Nord said: "I really can't suppress my curiosity. When I think of this kind of time, I don't need to explain too much.

Maybe what I’m waiting for is destruction, but I really want to go and see it.”

After Nord finished speaking, everyone fell into silence again.

Lu Yu looked at everyone: "Who else do you want to go and see?"

It was silent again, and then Xiaopang Brother, Chen Tianming, and Arnold raised his hands.

Lu Yu said: "Go, maybe this is our meaning. You have to carry our best equipment, well... bring the Time Traveler with you, maybe it will come in handy.

If we can come back, we will send a message in our own way, and I will find a way to pick you up.”

Alice was surprised that Lu Yu did not stop him at all.

However, when I recalled the separation from Julia, Alice felt relieved again. Lu Yu had already made mental preparations. When everyone could be together, they would enjoy the time to accompany each other. When it was time to say goodbye, don’t drag it on.

If you change into the most stringent protective suit, it is not an ordinary space suit, but a powerful armor equipped with Pangu core, such as the Iron Man suit, which can allow Nord and others to survive in the suit for more than 30 days and block most attacks.

The Crossing World was also strengthened for the last time by Lu Yu, dismantling unnecessary equipment and facilities so that the four people can be easily carried and used.

Standing in front of the interstellar gate, Nord and others did not look back. If they turned back at this time, maybe everyone would feel uncomfortable.

The interstellar gate is dialed and can be transmitted in one direction, but the other end does not seem to have any obstacles.

Four people quickly passed the Star Gate.
Chapter completed!
