From noon on the day they came back until the morning of the next day, Xue Qiong and Xiaoyun stayed in the room and never went out.

After breakfast, Xue Qiong went alone to the laboratory where Cha Yao used to experiment with weapons, where he began the cultivation he was now accustomed to.

For some reason, after the beacon prompted him to complete the strengthening task, there was no way to continue to improve his mental power by mere meditation, and now the only way to use training to prompt mental power is to keep repeating the process of draining his mental power, and then meditating to recover.

Combat may speed up the process, but not too much. Relying on such a little bit of accumulation, when Xue Qiong left Arad, his spiritual power level had reached the current level 21 from the 18th level of Arad assessed by the beacon.

As his mental power increases, some skills are unlocked. However, although the skill tree in the game can now point out a lot of skills, the current Xue Qiong can only use the Nian Qi Wave, the Nian Qi Wave Advanced Mind Cannon, the status skill Light Blade, and the simplest and no practical, at most as a clone for a temporary meat shield.

The reason is that Xue Qiong's own physical fitness, especially the flexibility of muscles and ligaments, is so poor, so she can't learn those foreign kung fu at all... Especially Xue Qiong was originally looking forward to the steel and iron bones that can passively improve the body's defense, as well as the housekeeping skill of female fighting in the game, so even if the advanced thunder back fall of the back fall has been unlocked, he still can't use it.

In addition, there is also the advanced phantom explosion of the clone, which can make the mental qi clone directly explode and cause damage, Xue Qiong also learned it, but... Unlike in the game, these clones actually hurt themselves when they explode!

With Xue Qiong's current mental power, he can already create six clones, but he can't control one more or less, and he can't control the location where they appear, that is, no matter how he thinks of it, these six immovable clones will surround him at an even thirty-degree angle of less than a meter... And it just so that he couldn't get out of the gap between the doppelgangers. In fact, the first time he unlocked this skill, he wanted to try the effect, but when he found that he seemed to be able to be blown up too... It was very aggrieved and stupid to stand in the middle of the six clones, and waited until the clones dissipated naturally before daring to come out.

It seems that the skill of phantom explosion can only wait until Xue Qiong's strength continues to improve, and he can only try again when he can use the Nian Qi Hood... I just hope that the effect of the air mask is not to be protected indiscriminately within the scope of the pit father.

In this way, Xue Qiong began to mechanically shake the air waves against a test steel plate... And he can't use the advanced Nian Cannon here, he can only use the most ordinary Xiao Nian Qi Wave to shake it one by one.

After the test of actual combat, the power of Nian Qibo was not as unbearable as Xue Qiong had thought before. Although its power is not large, it will not be directly fatal when it hits people, but ordinary people will at least lose their combat effectiveness when they are hit by the impact of this high-temperature energy group. Moreover, although the mind qi wave is an explosion that produces damage, the burns caused to people are more like the kind of burns caused by electric shock, and at the same time, it will also cause a paralyzing effect to the attacker, that is, even if the person is not blown down, the other party will temporarily produce a short movement out of shape or slow down because of this paralysis, and even be directly electrocuted to the ground.

In addition, there is another very interesting thing about Nian Qibo.

He had always been curious about what the "Shock State (a negative state, after this state, each time you are attacked)" that can be caused by the in-game Nian Qi Wave after it becomes an actual enhancement item, what will it be, but once when he was dealing with a demon wolf with some magical abilities, he found that the other party was relying on his natural magic protection power, and after eating a few of his own Nian Qi Waves, the protective energy layer on his body suddenly flowed chaotically... And when this happened, its original fur, which couldn't even cut into the strengthened bald head, was actually pierced by a small pistol that Xue Qiong took out temporarily.

Moreover, when the uncontrollable energy layer was pierced by bullets, those chaotic energies seemed to have found a catharsis point, and poured into the wound uncontrollably, causing secondary damage to the demon wolf...

Unlike in the game, this effect of interfering with the enemy's energy protection and causing them to take extra damage during the next attack can only affect enemies who have energy protection themselves, but not on targets that have no protection against energy attacks.

Xue Qiong also followed the statement in the game, let's call this effect an electric shock.

The boring waves lasted for about three minutes, and during this time, Xue Qiong threw out seventy or eighty memorial waves in a row, and his mental power bottomed out, and then he sat down cross-legged on the spot and began to meditate.

The test plate in front of him, which had been simply inscribed with the protective circle last night, was the experimental work of the few members of the researchers who were now studying the magic pattern. This magic circle is also connected to the magic energy converter, which is directly powered by the power supply in the test room, but due to the electric shock effect of Xue Qiongnian's air waves, the steel plate with the protective circle has now been beaten into a piece of scrap metal...

In the next few days, Xue Qiong kept repeating this relatively rare routine... In addition to the necessary daily cultivation, other members who were studying the magic pattern also often looked for him to sense the flow of energy in the magic pattern.

And after a few days, with the assistance of Xue Qiong, Xiaoyun, and Bald Head, three people who already have energy in their bodies, the members of the researchers finally came up with some results.

The first is the improvement of the Magic Grenade. With most of the runes already available for analysis, and with some of the large equipment that had just been purchased, everyone was no longer bothered to make anything like the thigh bones they had before.

The new magic grenade has an ultra-thick stainless steel cylinder painted black as the shell, and the weight of the entire grenade is eighty percent... In fact, such a thick case is just meant to be used as a counterweight that can be thrown farther away when in use.

The real core of the grenade is a piece of Mithril that is less than ten grams. Mithril is laser-engraved with countless runes that can only be seen with a microscope, most of them are energy storage runes, a few heat output runes, and a few switch runes. The principle is that switching the runes can activate all the energy storage runes, allowing them to instantly release the stored energy to the heat output runes, and before the mythril is melted, this process will end directly, and then instantly cause a high temperature of nearly 10,000 degrees Celsius in a small area, and then vaporize most of the matter in that range.

This time, the magic grenade can be directly charged and stored, and even the core that has already been charged is directly added when it is made, unlike the previous work, which can only be temporarily charged and detonated. In addition, the explosion mechanism of the grenade has also been specially added to the runes from the original error, so that the magic stored in it is unstable, and then the explosion is different, the new magic grenade is to use heat energy output runes to convert magic energy into heat energy, although the explosion range is not much different from the previous model, but it has become more stable, and the lethality is also concentrated.

Several of them make the new Mana Grenade no longer a weapon that can be thrown out of place for a long time during a premeditated sneak attack, but a regular weapon that can be used in frontal combat.

It's just that the energy storage ability of these runes surprised everyone, and they used the AC power supply in the laboratory to connect the magic energy converter, and they didn't fill it for a night, until the next evening, after more than twenty hours, the crystal on the magic energy converter dimmed...

And I don't know what kind of black technology the magic energy converter that was mass-produced as a cheap product in the reincarnation has what kind of black technology, a plug like a copycat charger can still run at full capacity after being connected to the largest power supply in the researcher's station, and it is not hot at all.

"You know, that's a whole thousand kilowatts! One million watts! Originally, when I pulled this line, I said that it was too wasteful, but this is already enough power to supply an entire large factory, and we can't use that much at all! At dinner, Huang Honghong snorted and ate the food in front of him, and said with his hands dancing: "And when charging, all the components are not hot!" In other words, almost all of the used electrical energy is charged, and there is no heat loss..."

Echoing Huang Huang's words, Zha Yao also said fanatically: "If there is no loss, twenty hours is a full 20 million joules of energy. That is to say, such a piece the size of a fingernail, it explodes ~ at least three kilograms of TNT equivalent!! Three kilograms of TNT!! At the time of the explosion, it was at least a hundred meters away, and everyone was going to die!! ”

"Hmm. One hundred meters is the distance at which TNT kills people. Unlike Zha Yao, Lord Bao prefers to bomb buildings, he added: "The enemies they will face next are probably not ordinary people, and the killing mechanism of this is also different from TNT, which is to directly vaporize things within the range, so the data I gave is... Twenty meters. Within a radius of twenty meters, no matter if it's a building or a monster, it shouldn't exist. As for the killing radius of ordinary humans, it should be fifty or sixty meters..."

The hacker next to him tapped on the calculator and said, "In the future, you still don't need to charge it with a power supply, this reserve... It is probably enough to drain the leader's spiritual power twice, which is much more convenient, and it can also assist the leader's cultivation. ”

Originally, Xue Qiong still had some specific concepts, but as soon as the hacker said this, he understood that the power of this grenade was about twice that of his Turtle Sect Qigong that was recorded as dead...
