The number of Zerg who attacked Xi'an was about fifty or sixty thousand, and after occupying Xi'an for two days, they divided a part of their forces to expand around, and when Lu Tianyu arrived at the outskirts of Xi'an, he found that the number of insects in the city was very small, and he didn't even see dozens of insects, so he hurriedly released an unmanned detector to look for traces of insects.

After more than half an hour of reconnaissance, Lu Tianyu found that the number of insects in Xi'an City was indeed very small, and the number of insects advancing in the east, west and north directions was not much, and most of the insects were moving to the southeast, and it seemed that they were either preparing to attack Lantian or wanting to attack Hanzhong again.

When the Zerg attacked Xi'an, they used wanderers to cross the Qinling Mountains from the south.

Lu Tianyu thinks that the main direction of the Zerg attack should be Lantian, of course, there is also Tongguan that can die in the east, but this gives Lu Tianyu a very favorable time to counterattack.

It is impossible for Lu Tianyu to recapture Xi'an with the troops in his hands now, but it is a godsend to block the small-scale troops sent by the Zerg, and he can use the small-scale Zerg as a whetstone for Zuo Gangchen's First Independent Division.

When Lu Tianyu was about to leave Xi'an, he found that thousands of insects rushed out of Xi'an City, and the direction was Sanyuan City.

"Is that the only one to reinforce the bugs?"

Lu Tianyu was determined in his heart, did not disturb this bug army, and even the wanderers who were the contact communication of the Zerg did not disturb, but only told Zuo Gangchen and Daniel Zhang the news of the bug reinforcements, so that the two of them could prepare in advance.

"General, the First Independent Division has not yet wiped out all the previous bugs, and the army also needs to take a short rest, preferably for half a day to a day?"

Zuo Gangchen also called Lu Tianyu a general, Lu Tianyu heard it a little strangely, but he also knew that Zuo Gangchen was starting to establish his prestige in the army.

"And what good advice do you have?"

Seeing that Lu Tianyu followed his advice, Zuo Gangchen said his thoughts and said: "The First Independent Division has now suffered hundreds of casualties and hundreds of wounded, the newly built army is not suitable for such an intense battle, many recruits are not even very familiar with the new weapons, and the cooperation between the various grassroots units is not very tacit, and at the same time, most of the soldiers have not entered the genetic strengthening, is it not to wait until the genetic reinforcement is carried out again, and then conduct a small-scale battle, which can allow the soldiers to have a new understanding of the genetic enhancement medicine." ”

When Lu Tianyu arrived at the outskirts of Sanyuan City, Zuo Gangchen's 1st Independent Division and Daniel Zhang's guard regiment had not yet finished fighting, and only after observing from a distance did they understand Zuo Gangchen's intentions.

The five or six thousand soldiers of Zuo Gangchen's First Independent Division were pressed and beaten by the Zerg, while the more than 800 soldiers on Daniel Zhang's side could chase the Zerg and kill, and the gap was too great.

Both sides are newly established armies, Zuo Gangchen's side still has a little advantage in weapons and equipment and numbers, but the combat effectiveness is much worse, Zuo Gangchen did not say it, Lu Tianyu now understands, he also wants to get the conditions and treatment that Daniel Zhang receives.

Indeed, in the battle with the Zerg, the quality of individual soldiers is very important, which is why Lu Tianyu did not form an army at the beginning, but organized the fighters into search teams and put them in various places for training.

In the short term, it is indeed not suitable for large-scale battles with the Zerg, and small-scale battles should be the mainstay, avoiding their edges, dispersing the forces of the Zerg, exchanging space for time, and not giving the Zerg a chance to mass-kill humans.

After thinking about this, Lu Tianyu came to Zuo Gangchen's side, sent all the First Independent Division into the array space, and under the cover of the guard regiment, while blocking the Zerg, he crossed Sanyuan City and retreated to Tongchuan City.

When the Qin army evacuated more than 100,000 recruits from Sanyuan City to Luliang Mountain, the first stop was passing by Tongchuan City, when Lu Tianyu threw off the Zerg behind him and followed him to Tongchuan City, most of the more than 100,000 civilians in Tongchuan City had fled, and some of the remaining people did not want to escape, but did not have time to escape.

When he arrived in Tongchuan City, the first thing Lu Tianyu did was to break up and reorganize Zuo Gangchen and Daniel Zhang's First Independent Division and Guard Regiment.

Although Zuo Gangchen was still the commander of the First Independent Division, the 5,000 or 6,000 soldiers in his hands were reorganized into 10 regiments, and there was no brigade commander level for the time being, and the number of people in each regiment was less than 600.

After the previous battle, Zuo Gangchen also found that it was not realistic to fight against the Zerg on a large scale, and it was better to break it into pieces and improve the combat capabilities of each grassroots level.

Lu Tianyu asked Zuo Gangchen and Daniel Zhang to recommend ten acting regiment commanders, and even asked Luo Jianda, the newly appointed deputy division commander, to personally select a regiment of soldiers to form the first independent regiment, and with Daniel Zhang's guard regiment to be responsible for the defense of Tongchuan City and defend against possible attacks by the Zerg.

The remaining soldiers were all screened for qualifications, and after lowering the awakening standards again, the soldiers who did not meet the qualifications were injected with the first stage of enhanced genetic medicine, and the remaining soldiers began to carry out awakening experiments.

"What do you suggest for me to do this?"

Lu Tianyu doesn't think that what he is doing is right, it is very necessary to listen to different opinions three times a day.

"General, is it really good to break up the guard regiment like this?" Daniel Zhang put forward his opinion.

Zuo Gangchen was very satisfied with the plan to quickly improve the first independent division, "It's not time to improve the strength of the guard regiment now, and after the strength of all the armies is improved, you can select excellent soldiers from our soldiers to supplement the guard regiment, and the overall improvement of the army's strength is the key." ”

Daniel Zhang's previous guard regiment had transferred a group of soldiers to supplement the First Independent Division, and now a large number of soldiers were being transferred, which made Daniel Zhang very unhappy.

Seeing that Daniel Zhang still wanted to fight for it, Lu Tianyu raised his hand to stop it and said: "Zuo Gangchen is right, in my opinion, the guard regiment and the first independent division are the same, there is not much difference between the two, and I don't need your protection, if there is really danger, you can't protect my ......." ”

Lu Tianyu figured out that what he lacked was real high-end combat power, if there was really danger, it must be an existence that even Lu Tianyu couldn't fight, so the real purpose of Lu Tianyu's establishment of the guard regiment was not to protect himself, but to protect his relatives.

Lu Tianyu knows very well what he is doing?

In troubled times, you must have the strength to stand in the world, if it weren't for the lack of skills in your own body and the inability to take care of too much, I'm afraid that even the army Lu Tianyu would not have formed.

"Tianyu!" Zuo Gangchen and Lu Tianyu sat together and chatted, and then changed their titles: "Vinyl Island is already forming an army, but the number of people is too small, and even the few sub-bases that have just been built cannot be defended, shouldn't we start expanding the army?" ”

Daniel Zhang had only known Lu Tianyu for a few days, and he didn't dare to trust the road: "General, what Commander Zuo said is right, I heard that the general has now gathered more than 200,000 people, but the number of troops together is less than 10,000, so if there is something, who will protect the safety of the base." ”

Lu Tianyu gathered nearly 100,000 people in Xi'an, Zuo Gangchen gathered 30,000 or 40,000 people in Xianyang, plus nearly 100,000 people on Vinyl Island, and now Lu Tianyu has more than 200,000 people in his hands.

However, among so many people, all kinds of technical personnel account for more than 30 percent, and the population under the age of 18 accounts for more than 30 percent, and excluding women, children and the elderly, the number of soldiers that can be recruited in their hands is indeed very small, and there is no way to do it.

The number of troops is insufficient, Lu Tianyu has always made up for it with quality, and inland Tianyu does not want to expand the army in a short time.

"The issue of army expansion will be discussed in two or three months!" Lu Tianyu said with a final word.

"You still don't know about Vinyl Island, after this mission is over, you will understand when you go back to Vinyl Island to rest for a while", Lu Tianyu understood Daniel Zhang's concerns, but never thought that the source of soldiers was the main problem restricting his development, because the most important thing in the end of the world was population.

Compared with Daniel Zhang, Zuo Gangchen was more concerned about the array space: "Tianyu, I think the array space is the main direction of our future development, the submarine base can only be used as a military base, life and research work should be gradually transferred to the array space, and the construction in the array space should be accelerated!" ”

Lu Tianyu also knows the importance of the array space, and it is similar to what Zuo Gangchen thought, the array space will gradually be planned as a living and research space in the future.

However, the array space is not big, it is not small, subject to resource supply and other problems, it is unrealistic to plan the array space in a short period of time, this is where Lu Tianyu really has a headache.

Lu Tianyu and Zuo Gangchen chatted for a while, then took Yue Yue and Zhao Yaqin into Tongchuan City, collected some materials casually, and entered the gravity ball to start their own cultivation.

Lu Tianyu stayed in Tongchuan City for twenty-four hours, the reason why it took twenty-four hours, on the one hand, after ordinary people were injected with the strengthening gene medicine, it took some time to adapt to the changes in the body, on the other hand, the awakened people who had been catalyzed by Emperor Jing also needed to adapt to their new abilities, and the twenty-four hours time was already very short, under normal circumstances, it was necessary to conduct seven days of adaptive training in the virtual system before it could be put into actual combat, but unfortunately now Lu Tianyu can only use war to support the war.

According to Zuo Gangchen and Daniel Zhang's statistics, more than 600 soldiers had successfully awakened in the previous 24 hours, and more than one-third of them had awakened their abilities.

This number did not exceed Lu Tianyu's expectations, these people can only be regarded as ordinary awakened people, and there is not much room for development in the future, it is good to be able to be promoted to the middle level of cultivation to account for one-third, basically there is no hope of being promoted to the high level.

Compared with Lu Tianyu's calmness, those awakened soldiers were much more excited, and after discovering that they could also become awakened, the mental outlook of these people changed qualitatively, and they all gathered together to experiment with their new abilities, making the whole scene almost like a circus.

Once the Zerg occupied that city, they would immediately send a small number of bugs out to scout around, and there were not many bugs occupying Mihara City, in the past 24 hours, Zuo Gangchen had been observing the number of bugs around Mihara City, and found that the number of bugs in it had not increased, so he immediately sent three regiments that had just been formed to launch a sneak attack on the bugs outside Mihara City in the east, west, and north.

The effect is very significant, by attracting and irritating those bugs, arrange the ambush point in advance, if it is a few bugs, sniper and kill, if the number of bugs exceeds a dozen, then switch to the tactics of group beating, hundreds of soldiers sneak attack together, often those bugs have not yet reacted, they are served by the soldiers.

The direct consequence of this was that the Zerg in Mihara City sent two or three hundred bugs at once, wanting to launch a crazy counterattack against the sneak attackers.

Obviously, the Zerg has not yet learned the tactics of adding fuel in human warfare, and they don't know how many of their opponents there are, plus the wanderers don't dare to go too far from Sanyuan City, which means that the Zerg has lost their reconnaissance ability, and when they find out that the Zerg are also pitted, it will be too late to send backup bugs.

"The Zerg in Sanyuan City hasn't sent rescue bugs for an hour, so I think we should wait for reinforcements from Xi'an!"

After two hours of digging work, Lu Tianyu was taken aback when he heard Zuo Gangchen's battle report and said, "How many insects have you eliminated this time!" ”

"About four hundred, less than five hundred!"

Lu Tianyu was taken aback by this number and said, "Doesn't this mean that there are only more than five hundred insects left in Sanyuan City?" ”

Zuo Gangchen immediately heard the subtext of Lu Tianyu's words, and hurriedly shook his head and said: "It is difficult to recapture Sanyuan City from the hands of the Zerg, we sent people to approach Sanyuan City, and found that there are more than a dozen pterosaur beasts entrenched in the city, these insects are too threatening to the soldiers, and if they attack strongly, they will inevitably suffer heavy losses!" ”

Lu Tianyu had confronted the Pterodactyl Beast, this insect was like a human fighter plane, and if there was no weapon that could kill it, it would be a nightmare for the combatants on the ground.

"Is there no other way? I really can't do it, I'm going to attract those pterodactyl beasts? ”

"It's not like there's no way!" Zuo Gangchen seemed to be waiting for Lu Tianyu's words, "If you can give us dozens more miniature electromagnetic cannons, I can use the trick to attract the Pterodactyl Beast outside the city and kill them all?" ”

If Zuo Gangchen had his own way to kill the Pterodactyl Beast, Lu Tianyu would not be willing to take action himself, not because he was afraid, but because he didn't want to participate in such a battle.

Lu Tianyu transferred sixty miniature electromagnetic cannons to Zuo Gangchen in one go, and the number of miniature electromagnetic cannons in Zuo Gangchen's hands reached a terrifying hundred, so that Zuo Gangchen specially set up the first artillery regiment, and even because of the temporary formation, the number of artillery was far from enough, so he could only temporarily transfer some soldiers from other regiments to act as gunners.

After an hour of running-in, Zuo Gangchen deployed this artillery regiment in a bush ten miles in the northern suburbs of Sanyuan City, and sent a regiment of troops to attract insects in Sanyuan City.

Maybe it was because the insects in Sanyuan City were scared, or maybe it was the reason why the number of insects in the city had shrunk sharply, but as Zuo Gangchen had imagined, the insects did not send ground troops this time, but directly used eight pterodactyl beasts to attack ...... out of the city.
