The Four Spirit Eight Blades are not only the most common spirit blades, but also the first batch of spirit blades, and they are the ancestors of modern spirit blades.

They were the first Blades...... It also represents the first generation of sword masters, and there is only the choice of these four spirits and eight blades.

At the beginning, the resources and technology were extremely limited, and it was quite rare for them to be able to break through the first spirit blade to the limit, not to mention the free development and infinite self-evolution, it was already extremely difficult to develop the eight paths.

The Vermilion Bird Sword, the Vermilion Bird Qin, the Green Dragon Spear, the Green Dragon Whip, the White Tiger Fist, the White Tiger Bow, the Xuanwu Shield, the Xuanwu Hammer, and the Eight Blades are all the main weapons, and cover the most commonly used types of cold weapons and tactical needs.

The original sword masters were not as wealthy as they are now, and the spiritual energy system was not comprehensive enough, and raising a spiritual blade had already gone bankrupt, and all their net worth was invested in it...... Or to put it more bluntly, that first blade is their entire belongings, all their combat power.

Since the Eight Blades have become the only reliance, the first generation of sword masters have desperately tapped the path and potential of the Eight Blades, and have turned it into a typical example that is easy to learn and difficult to master, broad and profound.

From the current point of view, the Eight Blades are indeed a bit congenitally deficient, and they are definitely colorless spirit blades, but the more expansion routes there are in the later stages, from pure attribute psionic amplifiers to the most dangerous attack weapons, and even elemental amplifiers, it is possible to develop.

"Actually, the four spirits and eight blades have corresponding elemental attributes, and there are still many elemental masters who will take the initiative to choose the eight blades. The Vermilion Bird is fire, the Green Dragon is wood and wind, the White Tiger is earth and gold, and the Xuanwu is water (ice), they have an inherent element of mutual restraint attributes, with the green dragon as the base, the Vermilion Bird as the blade, the wood makes fire, and the wind extends the fire, which is also a set of classics in the past with ......."

Fusion Spirit Blade is an ancient technology left over from that year, according to the relationship between the elements, the two spirit blades are actually combined into one, so that their spirituality increases, and the combat power and potential are greatly increased in a short period of time.

“...... Hey, isn't that amazing? Why doesn't anyone see it now? I've never heard of it. ”

The head of the dragon room shook his head, this skill is actually a double-edged sword, not everyone can play it.

"After the two are combined, the biological energy feedback is still calculated according to two, and the materials required for promotion will be more than twice as much, and the feedback will be twice as much, but in actual combat, you are equivalent to permanently missing a spirit blade, and even, one less spirit clan that may awaken, even if the success rate of the eight-bladed spirit clan awakening is extremely low......."

And what the head of the dragon room said more and more quietly behind him was the fundamental reason why the eight blades were not treated well.

The ordinary spirit blade is the projection of the soul product of the sword master on the spiritual material, the four spirits only play the role of medium and help, the adaptability of the sword master and the spirit blade is the highest, and the spiritual energy of the sword master is the best nutrition for the spirit blade, and the growth rate is relatively fast.

The birth process of the Four Spirits and Eight Blades is reversed, with the Four Spirits being the dominant and the sword master becoming the auxiliary...... As a result, the Eight Blades are born with low spirituality, and their growth at the soul level is extremely slow, and the probability of awakening the spirit race is quite low.

There was no bottleneck before the three sudden developments in the early stage, only the spiritual materials at the material level were enough, but because of the systematic experience route, it grew extremely fast.

In the stage of the Four Bursts, the experience is still useful at this time, but it is prone to problems...... Just like a child, you can arrange what he eats and learns, and when he becomes an adult, he naturally has his own personality and pursuits.

Spiritually inadequate, it is completely self-conscious, unable to give back what you need to grow.

The efficiency of blind feeding is too low, and it needs to be repeatedly explored and adjusted, and it may be that the spiritual materials saved by the previous three bursts will be used all at one time in the four bursts.

This is also the Qinglong Whip that Zheng Li easily helped Hu Yisaki at the beginning, and she was so surprised that she doubted her life...... I don't know what materials I need for my sword blade, how do you know.

Actually, Zheng Li really knows.

Born in a civilian position, it is natural for him to expect to follow the path of the past in an unfamiliar environment...... In the beginning, he relied on sword gambling-related work, and he earned a lot of contribution points within the intelligence agency (mentioned earlier).

And since the system of only four spirits and eight blades in the spirit blade is relatively fixed, he naturally starts with that, and the latest version of the four spirit and eight blades low-consumption formula is the product he has handled.

But then I found out that the situation was wrong, and if I continued, I would expose myself....... And the utility of this ability and formula is really limited, and the spirit blade is more about long-term cultivation, and a high starting point may not have a high return.

When he found that the world was too unsafe, and that a researcher could be high-risk and low-reward, he didn't go there.

However, there is an urban legend left along the way, there is a metaphysical master in a white coat in a small alley, and he has a special secret method to increase the shipment rate of gambling blades 100%...... Well, now that it hasn't appeared for a second time for too long, the legend has been spread as another rumor of cheating money.

In this process, his understanding of the four spirits and eight blades is quite profound, and the performance of the samples is generally similar, so it is possible to have research methods and rules.

Together, he has mastered a lot of secret methods of the four spirits and eight blades from various sources, such as the "Blade Melting Method" that is now used on Hu Yisaki.

The premise of its use is quite harsh, it must be almost the same as the spirit knife stage, and it conforms to the principle of mutual growth of native wood, wood begets fire, fire begets earth, native gold begets water...... In this era, one main weapon is difficult enough to raise, who will have nothing to do to get two four spirits and eight blades, and they have all evolved to a fairly high level.

Back then, this special technique was generally used when combat power was urgently needed, and it was used on a spirit blade with extremely low spirituality, sacrificing the future a little in exchange for powerful instant combat power.

In fact, strictly speaking, it can't be regarded as a sacrifice, after all, the two-in-one spiritual ascension can greatly increase the possibility of the awakening of the spirit race, and the main loss is actually to mean that the sword master will permanently have one less spirit blade that can be used.

"You're all four, too much. And I can't use it at all, it's not as easy to use as a 2-in-1 exchange, besides, you've been in contact with psionic energy for 17.18 years, not to mention that the spirit clan has awakened, and the consciousness of the spirit blade can't be perceived, and the spirituality is too lacking, what kind of garbage materials did you use to break through before......."

Zheng Li inquired, pulled a list, and determined that Hu Yisaki's spirit blade was indeed congenitally insufficient, the previous three spurts were all used as bargains, and the improvement of spirituality was quite limited, and there was no feeding of soul fragments (actual combat killing) on the way to promotion, in a sense, it had encountered the worst death bottleneck.

"I'm going to let the spirit blade break through again to get the improvement of the spiritual energy, to get the possibility of the fifth blade!"

"These four spirit blades have no sign of breaking through at all, and they are already 'dead'........ I want to have a fifth blade, and use the new blade to gain the possibility of a psionic breakthrough. ”

The eight-bladed choice that is too eager for quick success, as well as the repeated low-altitude and fast-level material selection that is eager to break through, makes Hu Yisaki's spirit blade extremely problematic, and the normal way can't solve it at all.

The weaknesses in this regard, one is that there are too many main weapons, and the human arm is limited, and more can only provide biological energy bonuses, which is almost equal to nothing.

And since the spirit blades are all weapons, and the defense and mobility abilities are all hard injuries, Zheng Li can't find a way to make up for it in a short time, so he can only take one step at a time.

The second is that if the spirit blade can't make the four sudden bursts for a long time, or the income is too small when the four sudden bursts are too small, she can't borrow every breakthrough opportunity to grow, and she will never be able to reach the fifth blade, even if she is completely stuck there.

This is a fatal wound for the sword master, but in this regard, Zheng Li is actually a little weak-hearted.

At that time, in order to prove his ability, the green dragon whip that helped Tiger Ichisaki break through four times..... The material used to pass through the lowest altitude is equivalent to giving up the qualitative change that this breakthrough may bring, and she is even more dead.

Now, even if the remaining three spirit blades successfully break through, they will still break through with thorough nutrition and sufficient materials, Zheng Li doubts that the spiritual energy evolution and upper limit of spiritual energy brought about by this will be enough to give Tiger Yisaki a chance to have the fifth blade....... Who said that no one has come to lay the foundation with all eight blades in these years, and they have passed all the way at a low altitude, and the foundation is really poor.

It stands to reason that the four three-sudden spirit blades should already have the feeling that they are about to break through, but Hu Yisaki always feels that the spiritual energy is insufficient, and the red phosphorus finger is still a big eater of spiritual energy, and the spiritual blade has been lacking spiritual energy for a long time.

In the end, after communicating with Hu Yisaki, he decided to adopt a mature and complete technical routine and try the blade melting method.

It took one night for Zheng Li to try out a lot of materials before he fused the Green Dragon Whip and the Vermilion Bird Sword together to achieve the current Flame Snake Belly Sword.

Until then, Tiger Ichisaki was still a little hesitant.

She wasn't worried about missing her primary weapon...... In fact, except for the White Tiger Fist, she didn't usually use any other spirit blades.

"What if..... If they have the potential to give birth to the Spirit Race......."

But Zheng Li bluntly told her that if she was spiritually strong enough to become self-aware, the integration would fail directly, and no one could accept being a part of others.

And if the fusion succeeds....... Well, this shows that the two blades themselves are spiritually deficient and dead, and they are congenitally deficient to a certain extent, and the crippled spirituality is eager to replenish itself.

Because the conditions of use are too harsh, it is also the reason why these skills are either stored or lost....... In the past, everyone was four spirits and eight blades, and no matter how harsh the conditions were, they could also be made up with numerical probabilities, but this year, those who have drawn out the eight blades have gone directly to the warehouse, and these secret skills and secret legends have naturally become the knowledge reserve of researchers.

There are only eight blades in total, and although the specific form of each eight-bladed is different, the weapon types will not be much different, and the Suzaku Sword may become the Suzaku Sword, but it is impossible to become the Suzaku Shield.

The sword whip (snake belly sword) that the Blue Dragon Whip and the Vermilion Bird Sword might produce was undoubtedly the result that Zheng Li most expected to see.

"31% of failures are unresponsive, 27% are unknown (many possibilities), and 42% are likely to have a sword whip. The time is too tight, or a little grinding, the success rate will be higher. ”

Undoubtedly, Zheng Li is also gambling.

But looking at the tiger Ichisaki who was chasing the other contestants on the screen in high spirits, Zheng Li knew that he had won the bet.
