"System level 2, the exchange mall is opened", almost at the moment when Lin Fei chose 'yes', the cold mechanical sound of the system came again, "Haha", Lin Fei was overjoyed, and hurriedly opened the exchange center to check.

Drinking water, food, medicine, weapons, daily necessities, everything, it seems that only Lin Fei can't think of it, there is nothing that can't be bought here.

"System, how can I buy the things in this exchange mall", Lin Fei asked, "The host is currently zero in the transaction point, and it cannot be purchased", the system said.

"Huh? Trading Point"? Lin Fei was confused, his mind moved, and he carefully checked in the system interface, and sure enough, in the upper right corner of the exchange mall, he found the three words 'transaction point', and the '0' written on the back was eye-catching and dazzling.

"System, how do you get this trading point"? Lin Fei asked, "The host can use the energy crystal nucleus to exchange", the system said, "............", Lin Fei couldn't help but be speechless for a while.

"I originally thought that with the mall, I would have no worries about food and clothing, food and drink, but I didn't expect that the goods in this would have to be exchanged for energy crystal nuclei, which is really a profiteer", Lin Fei complained fiercely in his heart.

"By the way, system, why did Kuroko suddenly become stronger just now"? Lin Fei simply incarnated into 100,000 whys, that is, the system is an artificial intelligence, and he is tireless, if he were replaced by a real person, I am afraid that he would have been annoyed to death by him.

"Pet sunspots were stimulated, emotional, broke through their physical limits, and advanced to the middle of the first level, so their strength increased greatly", the system explained, "But, didn't you say before that you need energy to advance"? Lin Fei continued to ask.

"Humans and animals, in certain circumstances, will push the limits, and in this case, even if the energy is insufficient, they can advance," the system explains. "Oh, I see", Lin Fei suddenly realized.

"Jiang Yu! Jiang Yu, how are you"! After asking the system clearly, Lin Fei endured the pain on his body and walked towards Jiang Yu, "Brother Fei, I'm fine, I can hold it", Lin Fei walked in front of Jiang Yu and helped him up with great difficulty.

"Jiang Yu, it is not advisable to stay here for a long time, then Wang Hai said that most of their men have been sent out to fight against the people of the Xingbei Gang, let's leave quickly while they haven't come back yet, otherwise when they come back, we will die", Lin Fei said while supporting each other and walking towards the truck.

Because both of them were seriously injured, especially Lin Fei, who was covered in scars, it took a lot of effort for the two to climb into the high cab, during which Lin Fei almost fell.

Lin Fei climbed onto the tanker, Jiang Yu climbed onto the truck, "Jiang Yu, can you still drive?" Lin Fei asked, "Don't worry, Brother Fei, although I took a few punches from that guy, there is still no problem with driving", as he spoke, twisted the key, started the car, the engine roared, one after the other, and drove towards the pet store.

"Detected mid-level energy overflow, whether to absorb it", the system, which had been quiet for a long time, prompted aloud, "Wow! Brother System, you have been quiet for so many days without moving, I thought you had a short circuit", Lin Fei joked.

"Due to the lack of energy, in order to save energy, the system has entered a semi-dormant state, this system is a product of high technology, and there will be absolutely no failure", the system replied at a glance, and it was not a joke at all.

"Well, your system is a wooden head, no humor at all, what's that energy overflow"? Lin Fei asked.

"The energy of the evolutionary is stored in the body, and when used in battle, it can give the evolutionary different abilities, and after the death of the evolutionary, these energies are unbound and will dissipate between heaven and earth," the system explains.

"What? Will it dissipate? Then absorb it quickly, don't waste it", Lin Fei was startled, he and Heizi worked hard to kill Wang Hai, and now this energy will disappear, Lin Fei can't help but want to slap his two mouths, why is he talking so much nonsense, wasting this energy.

Since Lin Fei and the system were spiritual exchanges, although they seemed to talk a lot, in fact, it only took dozens of seconds, and the energy only dissipated a little, and most of it was absorbed by the system.

"Enough energy, do you want to upgrade the system", the system's prompt tone came again, "Oh? Can you upgrade? Killing a Wang Hai actually provides so much energy? Lin Fei was a little surprised and chose yes.

"System level 2, the exchange mall is opened", almost at the moment when Lin Fei chose 'yes', the cold mechanical sound of the system came again, "Haha", Lin Fei was overjoyed, and hurriedly opened the exchange center to check.

Drinking water, food, medicine, weapons, daily necessities, everything, it seems that only Lin Fei can't think of it, there is nothing that can't be bought here.
