When Han Bai's brain gradually digested the foreign information, he was once again shocked by the powerful technological strength behind this doomsday killing game! Because even after he closes his eyes, he can still "see" the interface for redeeming rewards!

The reward redemption screen is as simple as the game promotion spray that day, and against the dark background of a lonely universe, there are various submenus, such as weapons, skills, functional items, team shops, forges, etc., including several labels "? The menu, but Han Bai can't find it. At the top of the interface, there is his basic information and two units, the survival point and the source energy. The "1000" is displayed after the survival point, and the source energy is empty.

"Skill? Is it really possible to use skills as in a game? ”

As soon as he thought of this, Han Bai directly put his spirit into the skill, and the next moment, rows and rows of long skill trees appeared in front of him, and he first started to look up from below.

"Normal person (functional), D-level, if your physical fitness is lower than the average level of that age group, redeeming this skill will restore your attributes to the average level of a normal person, note that this skill cannot repair physical disabilities such as broken limbs, blindness, burns, etc. Survival Points Required: 1000. ”

"Beginner shield (protection), D-level, to cast this skill, you need to consume a trace amount of psionic energy, the more psionic energy you infuse, the stronger the protective effect, but there is an upper limit and the protective effect is poor, the protection against blunt weapon damage is stronger than elemental damage, and there is no defense against mental damage. Survival Points Required: 500. ”

"Psychic Exploration (Support), D-Rank, this skill requires a small amount of psionic energy to be consumed. You begin to wake up in the psychic realm, gaining the ability to detect units within a radius of 100 meters, with poor penetration and inability to penetrate any psychic defenses. Survival Points Required: 400. ”

"Thunder and lightning mastery (support class), D level, to perform this skill requires a small amount of spiritual energy. You begin to wake up with the ability to convert your psionic energy into lightning and control it, either inflicting extremely small amounts of lightning damage or attaching it to an instrument. Redeem 300 Survival Points required. ”

……

"Can you really summon thunder and lightning after redeeming it? It doesn't make sense at all from a biological point of view......" Han Bai muttered to himself. He found that the most basic D-class skills were mostly support, and the other classes had fewer skills. He continued to browse upwards, and finally understood when he saw the C-level skills, it turned out that most of the D-level auxiliary skills were used to lay the foundation for more advanced skills, for example, the instructions on the C-level skill "Thunder Wave" were to be based on "Thunder and Lightning Mastery", and even if they exchanged "Thunder Wave" without learning "Thunder and Lightning", they could not be used. This type of support skill is equivalent to the lowest and most basic skill in the skill count.

Other skills, such as the "Beginner Shield", are not supportive, but you can still find the advanced skill "Low-level Shield" (C-level), but the functional skills are basically not advanced. However, at this stage, he doesn't have to worry too much about the exchange of advanced skills, but he has never seen any skills above level C below 1000 survival points. As for the B-level and A-level skills above, Han Bai can't browse it yet, probably because of the limitations of the system of the Doomsday Killing Game.

The exchange time was really limited, and Han Bai could only take a general look at the skill class, and then immediately transferred to the weapon class. The list of weapons was equally long, and he directly focused on the D-class classification, and those above the D-class simply didn't even look at it.

"Hey, this seems to be good, there are guns! Isn't that better than anything else at this stage? Han Bai exclaimed happily. What he has his eye on is a ** pistol.

**, Class D, range 200 meters, gun weight 2.05 kg, 200 rounds of normal ammunition included with the gun. Redeem 200 Survival Points required. ”

"Well, 200 points is very cheap, although 200 bullets are a little less, but saving a little bit may save a few lives...... Oh? Why does this knife also need 200 points? The same redemption points as a pistol? ”

The shape of the knife that Han Bai noticed was very ordinary, and when he looked at the introduction, it said: "Low-level spirit knife, D-grade, no attributes, can absorb trace amounts of spiritual energy, has poor hardness, and poor sharpness." Redeem 200 Survival Points required. ”

Han Bai continued to browse down and found that this phenomenon was not an isolated case! Among the C-level and D-level weapons, traditional weapons such as swords, bows and arrows, and hammer shields have higher exchange points than modern thermal weapons, and it can even be said that modern thermal weapons only occupy a small part of the exchange list, and their status is obviously not high! The most expensive weapon that Han Bai can find at a glance, the Barrett sniper, C-level, only needs 1500 survival points, which is basically the same as D-level firearms, and as C-level weapons, some expensive traditional weapons can even reach more than 3000 survival points!

According to common sense, the lethality of a Barrett must be much higher than that of a cold weapon, and if a martial artist with a sword and a soldier with a submachine gun go head-to-head, the result can only be slaughtered!

In a game as dominated by ultra-modern technology as the "Doomsday Killing Game", there should never be such a big imbalance in any way. The most reasonable explanation is that with Han Bai's current cognitive ability, he can't fully comprehend the mystery in the cold weapon.

Could it be that it is because Barrett's thermal weapon can be obtained in reality, so the exchange system disdains to give it?

But in that case, aren't cold weapons even less technological?

Yes! By the way, how to forget the most important things! Han Bai really wanted to pat himself on the head!

Psionic energy! Psionics!

Almost all the cold weapons in the exchange system involve the use of "psionic energy"! Although Han Bai still doesn't know what it is at all, he can guess it just by guessing, it is definitely an energy that surpasses Han Bai's current cognition! Maybe it's the same as the magic, vindictiveness, and chakra in novels and anime, and it's another power system that is different from modern technology!

Another system that distinguishes it from modern technology...... Hehe, if someone took out such a thing and discussed it with Han Bai an hour ago, he would definitely think that person's brain was squeezed by the door, but after suddenly experiencing so many "supernatural" events, even if someone told him that God really exists, he might believe it!

However, in any case, as long as the existence of psionic energy is recognized, the cold weapons that can absorb and use psionic energy in the exchange system are definitely very different from traditional cold weapons, and may even be far superior to modern technological firearms, and the products of "ultra-modern technology" may not be!

In this way, the phenomenon of the huge exchange value of cold weapons can also be explained!

Thinking of this, Han Bai had basically determined the direction of the first exchange, that is, attack first, defense secondary, and it was best to be able to use that mysterious "spiritual energy"!

Seeing that there were less than two minutes left in the exchange system, he no longer hesitated, and immediately issued an order to the exchange system in his mind.

"I choose to exchange for the skill Beginner Shield Cloak (D Rank), Thunder Mastery (D Rank), and Weapon Low Rank Spirit Knife (D Rank)!"

"Your total of 1,000 survival points is consumed in this exchange, are you sure?" A metal chime pops up in my head.

"Confirm!"

"After the exchange, the items you redeemed have been transferred to your 'Multi-Dimensional Link Table', which can hold the items exchanged in the exchange system indefinitely, and the specific use method has been entered into your mind. Now that you are learning the skills, please do not step out of the photosensitive channel for the time being......"

Han Bai stood in the pillar of light, and suddenly the light of the pillar of light began to change again, flickering bright and dark, flickering red and purple, and sometimes disappearing, at the same time, Han Bai felt hot and cold for a while, as if he had been irradiated, and his whole body was itchy, especially at the center of his eyebrows and the floating place, there was a faint feeling that an awl was piercing, but he couldn't bear this discomfort. Fortunately, the process of radiation from the beam of light is extremely fast, and everything is back to its original state in only a few tens of seconds.

Han Bai didn't detect the changes in his body for the first time, he chose to immediately close his eyes and continue to browse the exchange list, in order to better understand this doomsday killing game, he needed more information. In the last less than a minute, he flipped through the team shop and functional items, among which the interface of the former was unexpectedly empty, while the latter contained countless exchangeables like the skill and weapon interfaces, and after Han Baiyuan quickly jotted down a few important items with his eyes open, the metal prompt sound sounded again.

"Your time for using the exchange system this time has ended, please wait for the next time it opens, and the time will be ...... after the next task is completed"

The pillar of light in the air dissipated little by little, Han Bai looked down at the watch on his wrist, and suddenly his heart moved, and he said, "Come!" Then, a small silver-white pistol with a futuristic technology style appeared out of thin air in his left hand, which happened to be the same color as Han Bai's watch, and it was the "psionic gun" mentioned by the system before!

In his right hand, he already held a crisp war knife, and although the appearance was a little simple, it could not hide the shining blade. Even if this war knife can't be said to sharpen iron like clay, it is not too easy to cut off flesh and blood!
