With Gao Shan's company, Luo Tian looked at the various weapons in the armory. Although there were a lot of them, in terms of attack power, there was still a big gap between them and other star cities.

At this time, he received a message from Yelena, asking him to send his coordinates. After seeing the message, Luo Tian felt more at ease, which meant that Yelena's trip was safe.

Luo Tian sent his coordinates to Yelena through Kaiyuan, and Yelena soon arrived here, but because there was a firewall around the R&D base, people who had not been authenticated could not find this place.

"This is clearly an empty lot, where does the R&D base come from?" Yelena said curiously.

Luo Tian came out of the R&D base and saw Yelena looking ahead in confusion.

"Come here, I'll take you in. There's a firewall here, so you can't see it." Luo Tian said.

Yelena smiled and said, "You are amazing. The firewall settings actually escaped my eyes."

After Luo Tian led Yelena into the firewall, a huge spaceship appeared in front of them.

"What a beautiful spaceship! It looks a bit familiar." Yelena looked around the research and development base in front of her.

"This is our research and development base. I named it Red Witch. When I built this base, I thought I would never see you again, so I called it this name. Fortunately, you are by my side again now." Luo Tian said.

After listening to Luo Tian's introduction, Yelena suddenly felt a pang in her heart and her eyes became moist.

Seeing the sadness on her face, Luo Tian held her in his arms and comforted her: "Why are you still sad? From now on, we will be together every day and never separate."

Yelena nodded with emotion: "Never separate."

Luo Tian led Yelena into the base and showed her the armory.

"There are indeed a lot of weapons, but few of them are strong in combat. If we really encounter an attack from other star cities, I'm afraid we will find it difficult to withstand it." Yelena said worriedly.

Luo Tian nodded: "You really hit the nail on the head. What we lack now is high-tech weapons. Gao Shangang also told me that he hopes you can lead them in weapons research and development to develop weapons with stronger combat effectiveness."

Yelena laughed after hearing what Luo Tian said: "You really treat me as a teacher. I can teach you, but how are you going to repay me?"

Luo Tian said without even thinking: "I will repay you in the way you want me to repay you."

"Okay, it's a deal! How are you going to repay me? I'll tell you when I remember it." Yelena said.

"No problem. By the way, how was your talk with the Stargazing Society going?" Luo Tian asked.

Yelena pulled Luo Tian aside and whispered, "I have arranged a meeting with them and they agreed. The time is set for tomorrow morning. The meeting place will be randomly generated. The system will automatically send the coordinates at that time. This is also to ensure the safety of both parties. I feel that there is still room for cooperation."

"Then let's go to the meeting tomorrow. Do we need to bring anyone else with us?" Luo Tian asked.

"No need. Even if they want to frame us, they don't have the strength to do it." Yelena said confidently.

At this time, Gao Shan came up and greeted her, "Greetings, Queen."

"I just heard from Your Majesty that you wanted me to teach you how to make high-tech weapons, is that right?" Yelena asked.

Gao Shan nodded quickly and said, "That's right. We are now stuck in a bottleneck and can only stay at low-end weapons. Especially after reading your weapon secret book, I have a lot of questions. If you can help me answer them, I believe our research and development progress will be faster."

Ye Yiliana said: "Okay, then let me see where your doubts are, and we will study them together."

Gao Shan saw that Yelena agreed to his request and jumped up happily: "Thank you, Queen, that's great!"

Yelena and Luo Tian followed Gao Shan to the weapons research and development room and began to discuss the technical difficulties in the weapons secrets.

Gao Shan realized Yelena's broad knowledge and technical depth, and quickly opened up his research and development ideas. The two discussed for several hours without feeling tired at all.

After solving each problem, Gao Shan immediately called in engineers to work out the technical details. The entire team was like chicken blood, working at full speed. Before they knew it, it was already late at night, but they had no intention of stopping.

Luo Tian was worried that Yelena's body could not withstand it, so he said: "It's getting late, let's stop here and continue tomorrow."

Gao Shan looked at the time and realized that it was already very late, so he said, "Your Majesty, Queen, I'm sorry to disturb your rest. We have indeed gained a lot today."

Luo Tian waved his hand and said, "We are all here for Uranus City, so it can't be said that we are delayed. In fact, you are the ones who are working harder. It's already late at night, so you should go to bed as well."

"Yes, sir!" Gao Shan said and went out, telling the engineers that they could rest.

"I didn't expect that we've been chatting for so long today. I'm actually a little sleepy." Yelena stretched.

"I'm worried that you're tired. Let's go back and rest now." Luo Tian said.

The two quickly left Kaiyuan, returned to the bedroom, and soon fell asleep.

The next morning, Luo Tian woke up from his sleep and found that Yelena had prepared breakfast for him.

"Come and eat, try my cooking." Yelena said gently.

This was the first time that Luo Tian had eaten the delicious food made by Yelena herself, and he quickly finished it all.

"This is the most delicious breakfast I have ever had." Luo Tian exclaimed.

"You just know how to coax me. No matter whether it tastes good or not, you have to say it's delicious, because I am your queen!" Yelena said.

After breakfast, the two entered Kaiyuan and came to a secret room according to the random address assigned by the system.

"Have they arrived yet?" Luo Tian asked curiously.

"I'll go check it out." Yelena walked to the wall of the secret room and pressed a red button. A voice came from the other side of the wall: "We're here, we can start."

Luo Tian understood immediately that in order to ensure the safety of both parties, neither negotiating party would show up and would only communicate through the intercom on the wall.

An astronomer said, "Red Witch, what do you think of the conditions we proposed?"

Yelena then told Luo Tian the result of the discussion last night: "I'm afraid the current capacity of Tianwang Nova can't meet your requirements. It can only accommodate the residents of Tianwang District."

The stargazer said, "We can help solve this problem. And we also promise to provide you with digital reproduction technology. How about that?"

Yelena's eyes lit up when she heard this. She introduced to Luo Tian the power of digital replication technology. With this technology, the Kaiyuan world and the real world can be connected. Then the Tianwang District will surely usher in a technological explosion.
