Xu Fan saw the price on the exchange list clearly, and was startled, this price is simply a robbery, and the previous price is simply no way to compare, although the previous price is a bit high, but it is still within Xu Fan's affordable range, and now this price is simply to make Xu Fan vomit blood, no wonder the main program suggested that he exchange the Science and Technology Research Institute before the upgrade, and he thought that the Science and Technology Research Institute would not use too much energy, and when the space was harvested once, he would be able to exchange the Science and Technology Research Institute, I really didn't expect such a big change, now it takes 2000 space energy to even exchange a dog, and even a level 1 science and technology research institute needs one million units of space energy, which makes Xu Fan really feel that he can't afford it, at this time Xu Fan also feels that it is more reliable to upgrade, and he can upgrade the space by exchanging some things less.

Xu Fan suddenly thought of whether the human beings he had exchanged before wanted to make up the difference, so he hurriedly asked the main program, and then learned that all the things exchanged during the trial period did not need to make up the difference, hearing this news, Xu Fan's intestines were about to regret it, and he had always felt that the human and biological research institutes that were exchanged now were enough, so he did not exchange the others, but now he has to pay a greater price to exchange.

Xu Fan suddenly heard Wangcai's laughter, so he looked down, and just saw Wangcai in his arms covering his mouth with his two front paws, so Xu Fan patted it, "What are you laughing at?" By the way, you know in advance what will happen after the space upgrade, right? ”

Wangcai held back a smile and said, "Of course I know, I'm a space assistant!" ”

Xu Fan heard Wangcai's words, and angrily flicked his fingers on Wangcai's head, "You guy, I usually treat you so well, but you don't remind me at the critical moment, see how I clean you up in the future!" ”

Wangcai saw that Xu Fan was angry, so he didn't dare to joke anymore. Wangcai said aggrievedly, "Boss, this is not my idea, the rules of space are like this, the changes in space need to be discovered by yourself, boss, I can't remind it too obviously, otherwise my life will be difficult to protect, boss, can you bear to never see Wangcai again?" ”

"You guy, I'm really by you, okay. You go play with dog 1, I'll think about things. Xu Fan bent down and squatted down and put Wangcai on the ground, Wangcai thought that Xu Fan was still a little angry, so he ran around Xu Fan, Xu Fan waved his hand and let Wangcai leave.

Xu Fan is not disgusted with Wangcai, but he really wants to think about the future and upgrade from these spaces. Xu Fan also saw a little bit of the doorway, this space energy and space experience really can't be used at will, after getting out of the trial period, upgrading requires space energy and space experience. Spatial energy is required to exchange creatures and items, and it is really necessary to be cautious before using spatial energy in the future, so as not to delay major events.

Xu Fan took a closer look at the types of exchange and found an obvious difference. In the past, the levels of the creatures in the exchange list were defined by primary, intermediate, and advanced, but now the numbers 1, 2, and 3 are used to grade the creatures, and Xu Fan communicates with the main program. It is also known that the new exchange rules are different.

The primary creature that was exchanged before is equivalent to the current level, the intermediate level is equivalent to the current level two, and the senior level is equivalent to the current level three, the previous classification is relatively simple, and it is not worth dividing so finely, now each creature is rated by numbers, level 1 is the second, the higher the number, the higher the level, Xu Fan used to know that the bodyguards in the space are strong, but the specific data is not clear, after upgrading, there is a benefit, each creature will use data to display the level.

According to the information obtained from the external reality, the main program of the space determined the strength of the bodyguards in the space, and the normal combat effectiveness data of ordinary people in reality is about one hundred, which is still the data of people who are healthy and free of illness and disaster.

The combat effectiveness data of soldiers who have undergone three years of military training in China is generally about 500, the combat effectiveness data of China's general special forces is about 700, the combat effectiveness data of elite special forces can reach 1,000, and the combat effectiveness data of the most anti-heaven special forces should be between 1,000 and 2,000, but in the estimation of the main program of space, the number of such anti-heaven level special forces will definitely not be too much, because the training of each such anti-heaven level special forces requires a lot of financial investment. And the combat talent also has to be a particularly strong person to reach this step.

On the surface, the combat effectiveness of the special forces is not much more than that of ordinary soldiers, but the harsh training of the special forces has made them develop a more powerful combat instinct, and they have a great advantage in assassination and special operations, they can use their advantages, as long as they are not surrounded, the special forces want to deal with four or five ordinary soldiers It is no problem, but if the ordinary soldiers are on guard, with the cooperation of the team, the special forces are not the opponents of the five ordinary soldiers who are organized and defended.

The ability of elite special forces and anti-heaven special forces is stronger, and the number of general special forces is very large, the main program speculates from the information published on the Internet in reality that the number of general special forces in China is about more than 100,000, and the number of elite special forces should also be more than 5,000 people, as for the number of the most anti-heaven special forces, the number is less, but Huaguo has a huge population base, and this kind of anti-sky special forces must have at least more than 1,000 people in China, if Xu Fan provokes Huaguo's army, Based on the resources that Xu Fan has now, the main program can clearly determine that Xu Fan will be defeated.

After careful deduction, the main program specially instructed Xu Fan to try to provoke Huaguo's army if it was not very necessary, and now the space has just entered a normal state, and the main liliang is used to develop the space, and other aspects are exempt.

Xu Fan listened to the words of the main program, and repeatedly joked that the main program was too rigid, he was a Chinese, how could he do something to his own country's army, and he had no idea of rebellion, there was no dispute between the two sides, there was no conflict, and there was no chance to fight with the Chinese army, the assumption of the main program was too redundant. It's just that the world is unpredictable, and Xu Fan never dreamed that what he thought was superfluous would really be presented in front of him. (To be continued......)
