Both are crystal sources, and the red crystal source is a little different from the green crystal source. The Qingjing Source cannot be absorbed by the soul, and can only be repaired by the produced Qingjing Crystal, but the Red Soul Crystal can be used directly.

The crystal source is not a perpetual motion machine that can produce resources indefinitely, and the total amount of soul crystals that can be produced varies depending on the size. The small ones may be exhausted in one mine-drop period, and the large ones will not be exhausted in fifty mine-drop periods.

The piece of red crystal source that Bi Lingxiao took away was the only two storage of the thief group, and it was even larger than the piece of green crystal source that the four of them accidentally picked up in the green wolf territory when they first entered the thunder domain. With such a large crystal source, the number of red soul crystals that can be produced is also very large, and nearly one-third of the red soul crystals of the entire thief group are produced by it. Although it has been working diligently for more than 20 lightning reduction periods, the energy of this red crystal source is still very much, and if it is not consumed, it is completely more than enough to continue to produce more than a dozen lightning reduction periods of the red crystal source.

It's just that although the Red Crystal Source can be used directly and the effect is the same as the Red Soul Crystal, both of which can condense protective shells and weapons, but the strength has not reached the same height. It's not that the power of the Red Crystal Source is lower than that of the Red Soul Crystal, it directly absorbs the Red Crystal Source, and the shell it turns into is far superior to the Red Soul Crystal in terms of thickness and sharpness. However, if the red crystal source is left unplaced, it can continue to produce red soul crystals before the energy is exhausted, but if it is directly absorbed by the red crystal source, although it can greatly increase the strength of the shell and weapon in the short term, this level is definitely not comparable to the total energy that can be achieved by all the red soul crystals it produces.

Absorbing the Crystal Source directly is quite uneconomical, and in the long run, the benefits far outweigh the overall effectiveness of storing it to continuously produce Soul Crystals. Besides, the crystal source is so precious, and it is even more precious to be able to continuously produce more than forty thunder reduction periods, and no one would want to waste such an important resource if it were not for dealing with a battle with a huge difference in strength.

While this kind of behavior can almost be considered outrageous, it is an action that must be carried out for now. As the first group of the Qingyun Gang, the Green Wolf has a long history, a solid foundation, a large number of members, and a strong strength, even if most of the members were transferred to deal with the sudden attack of the Red Cloud Gang, there are still no less than two thousand members responsible for staying behind.

The establishment time of the thieves group is far less than that of the Qingyun Gang, and the number of members and resource reserves are far from comparable. The total number of people was only more than 5,000, and most of them were scattered to various strongholds to invade and guard, and in order to prevent the stronghold guards from escaping, these thieves were allocated far more supplies than before. These resources accounted for the vast majority of the expenditure, and the more than three hundred members who really went deep into the interior were not able to get too much rationing, even if they could deal with ordinary green wolf members, it would be difficult for a higher level of combat power to compete.

In addition to the few hundred people in the center, the main target of this team is the hundred elite guards in the storage area. In the case that one's own ration is not sufficient, and one's personal strength is slightly inferior, it is most important to avoid being consumed in advance. Since the reserves of the Red Soul Crystal in his hand are far from enough, and he has to deal with these hundreds of people on the premise of avoiding consumption as much as possible, at the moment, only the Red Crystal Source is the only choice.

Bi Lingxiao had just entered the realm of thunder, and even the Red Soul Crystal had not yet been able to control it proficiently, and he didn't know anything about soul power. The experience of fighting with Mochen from childhood to adulthood has profoundly taught him that in the face of absolute strength, all skills are floating clouds.

After absorbing the Red Crystal Source, the red spikes covering his whole body grew half a meter longer than the last time. The huge balls that were ejected from all sides were like explosions/bombs detonating in all directions of the field, and the speed was so fast that the explosion/explosion sound was almost connected. The resources of the green wolf members here have not been depleted, and the supplies can be said to be very sufficient, Rao is so, their protective shells are under the bright red sharp spikes, but there is almost no resistance!

Cries of pain rang out in all directions, and countless members of the green wolf were reduced to ashes under the bombardment of the giant ball. The entire central region was suddenly in chaos, and the members of these green wolves condensed various forms of weapons to try to attack, countless red rays of light flashed, but they did not reduce the impact of the giant ball at all, and only a few spikes that had been cut off had been quickly replenished at a speed visible to the naked eye. Eventually, they found that their own reserves of resources were far from being able to stop the ball's rampage.

They couldn't touch it, they couldn't hit it, they couldn't prevent it, and the souls who realized that the situation was critical had to give up resistance and hold their heads when they saw the orb flying. However, the speed of the stabbing ball was too fast, and many people couldn't dodge it, so they were pierced into a honeycomb on the spot and then scattered. Such a one-sided situation made the green wolves panic. They have no power to resist in the face of the attack of the giant ball, and can only be busy running to prevent themselves from being hit, and if this continues, they will be wiped out sooner or later!

"Don't panic, spread out, don't be targeted too much!"

In the midst of the panic, a spirit suddenly shouted. This person should be a captain-level person, hearing his words, the green wolves who were originally gathered together immediately dispersed, and in the process, several people failed to escape from the explosion/explosion and turned into green smoke.

"There is only one person on the other side, and there is always a time when it is exhausted! Everyone enters the tunnel to attack from a distance, and this guy can't do it in the narrow terrain!" Even in this situation, the man was very calm, and after a short analysis, he quickly gave the order. "One group, two groups, three groups set off from different routes and immediately deliver the message to the center, and the others quickly retreat!"

"All of us together can't solve this thing, why send three groups of members, if just one person is enough to deliver the message?" There were so many of them who couldn't deal with this thorn ball, and now they had to take almost half of the team, how could the rest of the team deal with?, but the man shook his head when he heard this.

"Since this guy can get here, he must have passed through the previous stronghold. We didn't hear anything until he broke in, don't you think it's strange, the outside stronghold must have been occupied! If you send only one person, you will be stopped, and if three groups of people go from different roads, one group will always succeed in passing the information out!"

Only then did the soul understand what his captain meant. Indeed, this is the center of the western district of the green wolf, and it is impossible for one person to walk here unharmed, and there are definitely many comrades behind him.

After receiving the order, the green wolves fled in the direction of the tunnels scattered on the stone wall, red light flashed, and the impact swept away the nearest few souls. The spikes almost touched the side of his face, and he couldn't escape the fate of being scattered if he took one more step. As one of the largest forces in the Thunder Domain, the Qingyun Gang, as the deputy captain, how could he ever be chased and run for his life like this?

"These hateful guys are really good at picking, just in time to start when our defense in the West Side is weak, it's shit luck!"

"Shit luck?" the captain looked bad. "You should hope it's just shit luck!"

The Red Dragon invaded, and the royal treasury mobilized most of the members of the western district to the eastern district to support, and this matter should only be known to the royal treasury himself and the people in the western district. As soon as the Green Wolf's troops and the Red Dragon fought, the Western District suffered an invasion, so quietly that no news came from the central area. Alone dares to break in, and the members who stay are really helpless against it. Could it be just a coincidence that such a bold action and accurate timing were made? If not, how did the news of the emptiness of the Western District's defense leak out?

By the time everyone entered the tunnel, the green wolf had lost nearly a hundred members. There was no target in the middle of the vast clearing, and the ball fell to the ground and stopped bouncing. The people in the tunnel didn't dare to act rashly, fearing that the thing would make some sudden move. In the center of the pitch-black field, the sphere stretched out, and the spikes around it slowly dissipated.

Bi Lingxiao, who revealed the true face of his soul, stretched his waist, rolled up the remaining half of the Chijing Yuan with his tail, then rubbed his hands, and rushed to the ground to take over. The crowd in the walls looked at the guy who was frantically collecting soul crystals scattered on the ground, and they were dumbfounded.

Stuffing the last crystal into his soul, Bi Lingxiao touched his stomach and was satisfied. Although these green wolf guards are just ordinary members, they should still have mastered the use of soul power. Although the bombardment of the thorn ball could easily kill anyone, Bi Lingxiao still received the rebound damage from the penetration. Although these injuries were far inferior to the elite team of the Royal Treasury, they still caused a lot of wounds to the soul, and it was only with the help of the Green Soul Crystal that it was able to maintain stability.

Although the strength of the thorn ball's ejection was extremely high, the cost was also extremely high, and after such a while, the two-color soul crystals he carried on his body had basically been exhausted, and even half of the red crystal source was left. The Red Soul Crystal is just that, and when it is used up, there is still a crystal source to squander, but the Green Soul Crystal has nowhere to replenish. Every time he hits a member of the Green Wolf, he will also be traumatized by his soul power, and if he doesn't have the support of the Green Soul Crystal, he will definitely not be able to support it for long. Just when Bi Lingxiao was distressed, he didn't expect the green wolves to choose to disperse in order to avoid the attack of the giant ball, and everyone entered the tunnels scattered all over the walls. This is simply a resource given for nothing, huh?

Without an opponent, Bi Lingxiao immediately withdrew the shell to collect supplies. This is all an additional supplement, with these soul crystal offerings, he can support it for a while! Right now, these green wolf people have been frightened by the indiscriminate bombardment he just had, and they don't know that the attack of the thorn ball also has a backlash against themselves, and now they have sent half of the members out to report the news, and they should not dare to act rashly for a while.

Now, his mission is to get rid of the guys in their retreat route before the vault is stolen. Looking at the green wolf members scattered on the opposite stone wall, Bi Lingxiao thought secretly. Behind him, in one of the tunnels leading to the storage area, thieves walked in between.

The giant ball rushed into the center, and with its almost unreactive speed and irresistible force, it shocked the members of the Blue Wolf on the spot. Everyone's eyes were on this huge ball of thorns that suddenly appeared for a while, for fear that if one of them didn't pay attention, the next one to be pierced into ashes would be himself. Not only the green wolves, but Tang Li, who was hiding in the tunnel and watching the battle situation in the center, was also frightened.

The thorn ball rushes into the central area of the green wolf, like a fireball falling into an anthill. The members of the green wolf had no resistance in the face of the sharp spikes, and at first they wanted to provide cover for their compatriots who were attacked, but they could only hug their heads and take care of themselves in the back. The first large group under the dignified Qingyun Gang, the core of the Western District of the Green Wolf, was actually single-handedly turned upside down by a soul carrying the Red Crystal Source!

Tang Li finally understood how the previous hundred-member thief squad escaped from the elite team of the royal treasury. This newcomer, his soul strength is extraordinary!
