Jiang Chen only waited a little more than a day, and the robot factory in the Huaxia Zhihui base had been upgraded. Before it, the metal processing factory had also been upgraded, so the current metal collection capacity reached 240 units per hour.

It has to be said that setting everything according to the level is a very orderly behavior, and it is easier to calculate gains and losses. Just like a metal processing plant can be upgraded to a maximum of 20 according to the Acre Technology division, and the ability to collect ores will be greatly improved. Of course, its area will also be expanded to an unparalleled level, and the consumption will be even greater.

The same is true for the robot factory. The robots that can be manufactured will be different every upgrade. Even each upgrade can be used to change and strengthen the low-level robots produced before, greatly improving the work efficiency of the robots. After the level is high, it can even produce combat robots. In the later stage, there will be large robots with strong air-to-air ability, which is not inferior to human mechas.

However, this involves some technology and requires the support of high-level science and technology laboratories.

Fortunately, the "WD-1" mecha that Jiang Chen is going to transform now is actually only equivalent to a low-level robot of the Akeleton Clan. The only difference is that the low-level robots produced in the robot factory do not have a weapon system installed, because the value of these low-level robots in the Akeleton Clan is as low-priced labor. But this is actually irrelevant. As long as Jiang Chen makes a slight change to the structure of these robots, he can easily turn them into combat robots.

This is what he has started to do now, and at the same time, he has also begun to upgrade the technology laboratory.

At this moment, a slight tremor suddenly came from his fingertips, and Che Ying's avatar also appeared in front of Jiang Chen. During this period, because both of them were very busy, the number of contacts was greatly reduced compared to before. At least Che Ying's request for daily contacts has almost become empty words, so Che Ying's expression at this time is understandable. Jiang Chen was stunned at first, and then smiled embarrassedly. Yes, he was only concerned about too many things during this period, and even neglected Che Ying without realizing it.

"Hmph! If I don't take the initiative to contact you, will you forget me completely?" It's rare that Che Ying will have the same considerations as ordinary women now, and she actually cares if Jiang Chen has her in her heart.

"Ahem...Yingying's wife, I'm wrong. I've been too busy for a while. I'll be careful next time!" Jiang Chen was a bachelor and apologized decisively, because he also felt that he hadn't 'reported' to Che Ying for a long time, which was indeed a bit unreasonable.

"..." It seemed that Jiang Chen would take the initiative to admit his mistake. Che Ying was stunned for a moment, because Jiang Chen seemed to care about other people's eyes for a long time... Because of his inferiority, he was self-esteem, so even if he knew that he was wrong, he would not be able to hide his stigma. Such a person is not Jiang Chen. "Okay, since you already know that you have done something wrong, then I won't blame you. Is this the base you built during this period?"

"Yes, I'll name it...Huaxia Zhihui."

"Huaxia...zhihui." Che Ying pondered for a moment, "How could you give this name?"

"Because..." Jiang Chen showed a bright smile, "Wife Yingying, in the near future, I will give you a big surprise."

"Surprise? Do you have any new ideas now? Or... are you doing something hidden from me?"

"Well, um... I have many new ideas now and are putting into experiments. If you can confirm, your dream will become easy, I promise!"

“…”

“…”

"So, husband, can you introduce me to your secret base now?"

"sure!"

"Didi...Warning!Warning! UFOs jumped into outer space, coordinate XXX, and were quickly entering the planet's range!" Just as Jiang Chen introduced Che Ying to various building functions in the base, a sudden detection radar sounded a harsh warning and a prompt sound. Jiang Chen was stunned at first, and then looked at Che Ying, "Have your B-13 fleet sent a ship again?"

"No! We're all busy preparing recently..."

"Isn't your spaceship?" Jiang Chen's face condensed on the spot, then quickly connected to the computer of the college's underground base, and immediately turned on and triggered the college's defense system. Then, through the college's radar scan, it was discovered that this was a large main destroyer belonging to the Federation, but it deliberately eliminated all the signs, without numbers or banners, and even deliberately sprayed some colorful things on the outside, as if they wanted to disguise themselves as pirate ships.

But how could pirates get the main destroyer? There is no doubt that the arrival of this warship is absolutely malicious!

The college immediately issued a wireless warning signal, asking the other party to inform them of their purpose and purpose, but the other party ignored them at all. At this time, it was already quickly passing through the atmosphere to prepare to enter the inner space.

So the battle alarm sounded immediately, and the firepower system of the academy was exposed from the ground, and the combatants immediately took their place. All the students were quickly transferred to the security cover facilities underground, and the small battleships of the academy were also ready to take off... But here Jiang Chen suddenly showed a strange look, because he scanned the academy's combat radar and found that the warship did not mean to invade the academy, but avoided the range of the academy's effective defense firepower from afar, and rushed towards the uninhabited area of ​​the academy planet...

But is it really a no-man? Of course not, because the Fourth Team is now outside the academy!

Or, this warship is just for... the glory of China?

Is there a traitor?

At this moment, Jiang Chen's eyes were opposite to Che Ying, and then he nodded to her, "You have to rest first, I will handle this matter!"

"The Jingyun has jumped away! My Jingchen account will jump in one minute..." Che Ying also nodded, his face cold. "I will arrive at the periphery of the academy planet in an hour. Husband, take good care of myself and wait for me to come!"

"Um!"

‘This…’ Jiang Chen’s video wave suddenly opened in front of Yue Bing, Wei Dan, Tang Qing and others. “Bingbing, quickly call everyone in the fourth team and let everyone leave the warship, hurry up!”

"What's wrong? What happened?"

"Enemy attack!"

"What?"

"Again, this is not an exercise! After everyone leaves the battleship, they will immediately put on the equipment and weapons in the badge, and I will arrive next!"

"Everyone, get up immediately and go outside the battleship to find a place to hide!" Yue Bing immediately issued an emergency assembly order using the watch in his hand, and then rushed out first. Then the members of the fourth team followed urgently one by one, but most of them still didn't know what was going on outside, until Jiang Chen finally appeared.

"Where is Instructor Xia Rui?" Jiang Chen looked around.

"I just went to her room to inform me, but she was not here..." Yue Bing frowned slightly, "What should we do now? Are we going to find her?"

"No need." Jiang Chen shook his head slightly, "The enemy has arrived. Now you all put on your equipment and turn on the signal shielding system on your left. From now on, all communication facilities will not be used. Similarly, the enemy will not be able to scan our traces. Now you all obey my command and go!"

...

Jiang Chen guessed right, the invading main destroyer was indeed coming to the Fourth Squad. After it arrived above the Fourth Squad camp, it immediately launched several small landing crafts. Then, a large number of landing combat team members quickly surrounded the small warships that the Fourth Squad had lived in before. However, they had found nothing when they forced into the warships. However, these people were not discouraged. Instead, they tied the small warships to the main destroyer brought to the air with several landing crafts. Then these landing combat team members dispersed around and began to search for traces of the members of the Fourth Squad.

Unfortunately, all members of the Fourth Squad are now wearing armor with shielded scanning, and the current federal radar scanning technology cannot scan their existence, so these landing combat team members have to use the most primitive means to find the escape traces of the members of the Fourth Squad, and they were really found, but...

Under Jiang Chen's huge mental power scan, every move of these people was under his full surveillance, and in fact, all the traces left were intentional...

"Zi...Si Wen, the target has one minute to enter your range and kill the one at the end!"

"Tang Zhen, your movements are smaller, don't make too loud noises. Remember, I want to live!"

"Nona, three people approach you and lead them to the trap!"

"Li Enzhu, shoot their legs!"

"Lin Zhen, are they in here, are they ready? Open the fire!"

"Guma, you take Lin Zhen away now! Speed!"

“…”

...

"Captain, our combatants are losing contact quickly."

"Hmph! A group of incompetent guys, but you can't handle the student soldiers? Send me two more squadrons!"

"Captain, it's been too long. There seems to be troops from the Huaxia Academy preparing to come..."

"They come if they are not afraid of death!"

"Captain! The detector we left behind discovered space fluctuations, and a large warship was jumping and teleporting over!"

"It was the B-13 fleet that arrived! They were still protecting this place... how many fluctuations have been detected?"

"One...wait, Captain, another one appeared!"

"Do you two warships? Notify everyone to return immediately and we will leave immediately!"

"Captain, I'm afraid that this time they will be alerted. They will be prepared in the future and will never have such a good opportunity next time!"

"I know, but we can't meet the B-13 fleet. They will know where we belong at just one glance! As soon as the combat team members return, we will jump and leave immediately!"

"Yes, Captain!"
