After everyone laughed enough, Song Qingge asked the system again, "The system, you just said, the world mission will no longer reward things about technology, so what will be rewarded?"

"I can't tell you the specific rewards for the time being. After the host completes the next world mission, he will naturally know."

"Tsk! You are sincerely trying to confuse my appetite, forget it, who made you the system?" Song Qingge couldn't help but be speechless.

Song Jinge took back the system task panel displayed for the ship's mother. After returning, a technology tree option appeared on the main panel of the system. After he tapped it with his finger, at the end of the tree diagram, he saw the familiar large characters, modernization, and modernization, and these large characters were golden. Next to modernization are several terms connected by horizontal lines, namely modern torpedoes, modern missiles, modern naval guns, modern carrier aircraft, and modern radars. And their respective classifications appeared above. For example, terms such as kinetic energy weapons, energy weapons, and ion weapons appeared on modern naval guns, while energy torpedoes, strong kinetic energy torpedoes, and ion torpedoes appeared on modern torpedoes.

With a somewhat familiar feeling, Song Qingge clicked on the modernization and found that the core of the transformation that could be exchanged with 3000 exchange points has now become a modern core material. Then, he clicked on the modern hull structure with the gray name and found that a special line appeared.

"Modern ship structure requires modernization (11) and modern core materials (03)."

Seeing this line of words, Song Qingge finally understood what the system just said about the science and technology tree. "System, you are a player of P Club? Otherwise, how do I feel that your science and technology tree looks like a group of stars?"

"Please don't slander the system out of thin air, and shoot all P players, none of them are wronged, and there are fish that have slipped through the net. As for those Class A war criminals, how can the system go with them?"

Song Qingge rolled his eyes, revealing the ingredients, my system. "Then can these materials be redeemed from the system store?"

"Yes, in principle, as long as you have redemption points, you can immediately organize a galaxy fleet."

Song Qingge nodded, and continued to look towards the science and technology tree, only to see an aerospace warship transformation above the modernization transformation, and beside it, there was a nuclear kinetic energy transformation. I clicked on the air-to-sky warship transformation and found that there were quite a few conditions needed inside.

"The transformation of air and space warships needs to achieve all the results of modernization (01), nuclear kinetic energy transformation (11), aerospace core materials (010)."

Song Qingge grinned and opened the system store directly. As the system said, the previous naval guns and other weapons had disappeared, and some materials were replaced. There are modern core materials, modern missile materials, modern torpedo materials, modern carrier-based aircraft materials, etc. and the prices vary. For example, a modern core material has now become 1,000 redemption points, but in general it is much cheaper than before.

"I found that the system is calculated like this, and the cost of renovation is much cheaper than before." Song Qingge said with a smile looking at the price of the material in the exchange store.

"Of course, the host now has a mature technology tree. The cost of making items by himself is of course much cheaper than the cost of buying them from others."

"That's what I said." Song Qingge couldn't help but nodded, then pointed to the aerospace core material in the exchange store and said, "Why does this core aerospace material cost one million? Are you blackmailing?"

"Aerospace is a new technology that the host hasn't touched before. It needs a little more resources to open it. Isn't it right?"

"Um... you're right..." Song Qingge said in a daze. After all, if you count it, the number of redemption points that aerospace transformation needs to open is at least more than ten million points. I originally thought I had more than 10 billion, and after redeeming my points, I was a rich man, but I didn't expect that the system would randomly release something like a science and technology tree, which made me feel like a poor man in an instant.

So Song Qingge looked at the smiling ship mother and said, "You have already heard the conversation just now. From now on, I will click on the technology tree as soon as possible, and then strive to make all the ship mothers in the port area aerospace transformation. Let you have stronger strength."

"It's okay, Commander, we now know roughly what the science and technology tree is. After that, you can decide the specific transformation direction. Let's take a look at the second reward of the world mission. "At this moment, Hood on the side said with a smile.

Song Qingge nodded, opened the backpack that came with the system, and quietly lay a bottle of medicine inside. Song Qingge took it in his hand and looked at the explanation carefully, "The life evolution potion, this potion is the commander's special potion, and must be taken after taking the evolution potion. This potion is extremely powerful. Please take it in a place where no one else is. Hurt the innocent."

"Is this life evolution potion the earliest follow-up potion of evolution potion taken by the commander before? Can you show it to me?" After hearing Song Qingge's explanation of this potion, the tester spoke to Song Qing Ge.

Song Qingge nodded, and handed the life potion in his hand to the tester sitting aside. The tester took the potion under the attention of the ship's wives and held the potion in his hand, flashing streams of light in his eyes from time to time. When everyone was puzzled, the observer on the side explained, "The tester is testing the ingredients in this medicine."

After listening, everyone nodded. In fact, everyone was very interested in the ingredients in this medicine. But because Song Qingge drank the earliest bottle of Evolution Potion, there was no chance to do a similar test again.

After a while, the light in the tester's eyes stopped, his eyes became flexible, and he spread out his hands and handed the medicine in his hands to Song Qingge. "I can't distinguish the ingredients in this life evolution potion. It is probably something from higher technology. However, I felt a violent force in it. After drinking it, I might become mad, so this is why this potion is used. The reason why you let the commander use it in an unmanned place."

Song Qingge took the medicine in the tester's hand and nodded slightly, "Don't worry, I have always been very knowledgeable about the quality of the system, so if I want to drink it, I will look for a place with no one."

"However, this medicine only wrote the precautions but did not write what its function is, which is really strange." The tester said.

"I think it should be the same type as the evolution potion I drank before, otherwise it is an evolutionary version of it." Song Qingge smiled, "It just so happens that I also feel that my strength is a little weak now, this potion The emergence of "to make up for the shortcomings in this regard, for the future world, then we will be more sure."

"Hehe, because the Lord is our pillar, I believe the Lord will take us to victory in the future!" Tiancheng smiled.
