The defeated giants tried their best to talk about idle days.

As if wearing an orange holy armor on his body, the defense of the Tanta giant increased dramatically, and Huang Fangxiang's fist hit it as if it hit a piece of fat, slippery and powerless, at least seventy percent of Huang Yu's strength was removed, and the remaining strength was no longer enough to make the giant retreat, and the Tanta giant slowly straightened up and pressed towards Huang Yu.

"Good. Huang Yu still had time to spare, and the next moment, the law minister crossed his arms in front of him, and he actually gave up the attack and defended.

Orange spiritual power protector, Tanta Giant's attributes have improved in all aspects, and when he hits a punch, Huang Yu also has to retreat, not to mention that he also played a set of combinations, and his fists and feet were used, but fortunately, Huang Yu's reaction speed was fast enough, and he defended them one by one, except for retreating, there was no defeat.

"It has been confirmed that the target is Huang Yu, another giant has no data in our database, it needs to be sent back to the headquarters for identification, Huang Yu has extremely strong combat ability, has reached the energy level of low-level battleships, can summon the law phase, and the duration is extremely long, the battle has been one hundred and ninety-five seconds so far, the fastest punch speed of the law phase is five hundred and eighty meters per second, the speed of the yellow language itself is slightly slower, the punch speed is three hundred and sixty meters per second, and the strength is ...... Huh?" "I don't know when a small flying insect that is difficult for ordinary people to see with the naked eye came to the edge of the battlefield of Huang Yu and the two, and actually recorded all the images of the two of them fighting until now, and analyzed it to the head, but at this time, it was grabbed by a hand, and the image became one of Huang Qiang's eyes.

"Micron-level spy machine flying insects, there are technological forces infiltrating, it seems that my monitoring scope is going to be expanded. The machine flying insect in Huang Qiang's hand was destroyed by a burst of energy, and he muttered to himself, it can be seen from this machine spy that the other party's technology level is not high, and he is more than enough to deal with it now, but he still feels a sense of urgency.

The Tanta Giant punched hundreds of punches and kicks in one go, and Huang Yu resisted them all, but after retreating more than a hundred meters, the Tanta Giant's attack did not stop at all, his power on the earth was unlimited, and he could maintain such an attack for several days.

"Huh" Huang Yu blew out a breath in his retreat, hitting the sole ......of the Tanta giant's foot, a hole appeared, and his law was also blown out in one breath, but it was the right shoulder of the Tanta giant, the giant moved, and the pain under his feet came and he almost fell, and involuntarily took a few steps back. The orange light on the giant's body not only increases defense, but also increases strength, but the defense is all-round, and small attacks can break through the defense, so Huang Yu's own attack can pierce his defense, but the breath of the law phase is only effective with strength.

"Fireball!" Huang Yu's right hand flipped, a football-sized fireball appeared above the hand, and then the left hand pointed at the left arm of the Tanta giant, the fireball flew away, accurately hit the giant, after the giant suffered a loss, he didn't dare to underestimate Huang Yu's own attack, so he consciously defended, the orange light of the arm flashed, resisting Huang Yu's fireball, but the fireball of the law flew immediately, there was a fireball the size of a small villa, the power was naturally much stronger than Huang Yu itself, and it hit the giant's shoulder with a bang, almost knocking the giant down.

"Ice Gun!" Huang Yu's previous fireball was just a small test, and he didn't expect that the power would increase so much when he put it in the law phase, this time the ice gun sent out seven points of force, aiming at the giant's left hand, and deliberately controlling the law phase to put the target there, he was quite afraid of hurting the giant at this time.

The explosion on the giant's shoulder has not completely dissipated, there are still flames, but the giant has already reacted at this time, his right hand is raised, and a huge wall appears between Huang Yu and him, Huang Yu's ice gun pierced the giant wall, but it can't enter again, the ice gun of the law is huge, directly smashing the wall, and then hitting the giant's left hand, although it did not cause puncture damage, but its entire left hand was frozen.

"Remarkable. Huang Yu praised it, he now felt that if he didn't use the law and weapons, he wouldn't be able to defeat the Tanta giant.

While praising and not idle, he pressed his hands on the ground, and countless ground thorns appeared at the feet of the giant, and the law was immediately launched, the ground thorns were high and low, large and small, and the highest had reached the giant's knees, but it did not cause any damage to the giant, but made it grow stronger.

"Uh......" Huang Yu was a little annoyed, he actually made such a stupid move, and the price he paid was that he was smashed by the giant several times, and he had to regain the initiative again in one breath, after this time, Huang Yu took turns to use the basic spells he mastered, and he didn't dare to release the earth attribute spells again, forcing the giant to retreat again and again, and the giant would occasionally release ground thorns, Earth walls and other earth attribute spells, but under the attack of Huang Yu and Faxiang, the role is extremely limited, and there is no possibility of reversing the situation, but Huang Yu pressed the giant to fight for at least three pillars of incense before he admitted defeat, the giant's endurance is too strong, Huang Yu suspects that he will not be able to survive if he continues to fight, and when he finally wins, he realizes that his spiritual power is only a little left, and he can barely fly back to his residence.

There are several major problems in the world of cultivating immortals, the first problem is how to open the two libraries of light and darkness, which is also the biggest problem that Huang Yu is facing now, since that day after a battle with the giants, Huang Yu feels that if he cultivates the two libraries of light and darkness to the peak, the law phase will be complete, then not only the cultivation will be improved, but the combat effectiveness of the law phase will be greatly improved, so from that day on, he has been working hard in this area, but it is a pity that the progress of a person's exploration is too slow, and he has searched through the classics of the Yaochi faction and has not found such experience, and he has no reference in front of him.

"The old dragon told me that the dark vault and the light vault are both at the top of the back of my head, and it wouldn't be wrong to look in that direction, but he didn't tell me which side was light and which side was dark, but fortunately I had one or two references to the "Dark Night Biography" by Suigetsuan. Huang Yu took out the biography given to him by the host of Shuiyue Nunnery, Jing'an, and studied it carefully, but he did not find any such records, most of them were dark attribute spells and the influence of dark attributes on people.

After that, during his cultivation, Huang Yu tried countless methods, but he couldn't open the two libraries of light and dark. Until the dawn of one day, the intertwined light and dark in Huang Yu's eyes gave him a hint of inspiration, perhaps, the light library and the dark library are opened at the same time, so that the two spiritual powers of light and darkness must coexist first, Huang Yu has done similar things before, but those are other attributes, the light and dark spiritual power will dissolve as soon as they meet, and the speed is so fast that he can't even react, this seems to be an unsolvable problem, but in addition, Huang Yu has tried almost all methods.

The retreat was fruitless, Huang Yu found Huang Qiang, and the two turned on the chat mode, while Huang Qiang turned on the bragging and teaching mode, which is what the two of them often do. Huang Qiang has always considered himself to be the instructor of those twenty young people, in fact, he did the same, and he was very responsible for customizing a cultivation plan for each of them, and strictly controlling the implementation and implementing militarized management, which has been quite effective.

"I don't see you cultivating, why did you reach the Jindan stage so quickly, and it's the middle stage. Huang Yu asked, he usually asked a word, and then there was nothing for him, and the following was all Huang Qiang's words.

"The principle, after figuring out the principle, it is implemented, this kind of problem is only a bit difficult to figure out the principle, as for the implementation, it will be replaced by the micron-level robots in my body, they will transform my body, find the Kumen, guide the spiritual power to enter, and slowly compress it into Jindan. So, do you know what Jin Dan is all about?" Huang Qiang asked, in fact, it was like asking himself, because he didn't give Huang Yu time to answer at all.

"Jin Dan is a solid spiritual power entity, there are aura in various spaces in this world, the so-called aura is a kind of extremely fine particles, which can be absorbed by the human body and converted into a denser spiritual power, spiritual power is a kind of dense spiritual energy particles, it is more appropriate to use a liquid metaphor for spiritual power, this dense degree of particles can be controlled by the human body, and in a certain way can be used to strengthen itself or compose a certain attribute of energy, the application is all about the heart, when all the space in the human body is filled with this kind of spiritual power, it will reach the peak of this stage of spiritual emptiness, that is, there is no space in the body that can accommodate spiritual power, It seems that the spiritual void should be the pinnacle of human monks, but we special people still have a mysterious space with us, that is, the existence of what is called the library, the spiritual power is compressed into the library, the library is very small at first, and it can't accommodate anything else, but the spiritual power can, and it must be extremely pure spiritual power before it can be pressed into the library, and the limited space of the library itself or a certain function will compress the spiritual power and compress it into a solid, which is the golden pill, so the spiritual power of the golden pill is much stronger than the spiritual power in the body, that is a difference in texture, understand?" Huang Qiang always slowed down with a question, and then continued. Huang Yu said in his heart, his own library is very wide, so it should be that the library itself has the function of compressing spiritual power.

"The robot in my body is not enough to capture that particle, but it can drive a large group of spiritual power, which means that I don't need to control the spiritual power myself like you to achieve the effect of cultivation. Hmph, my body has already completed the transformation of the micron level, with the assistance of robots, any part of my body can be turned into a weapon, and it is not limited to the cold weapons of this world, there are also various technological weapons, such as missiles, railguns, electromagnetic ballistic simulations...... Even lasers can be simulated, not forgetting the two little missiles I supported you before, those are my two fingers, and now the damage on my body can be repaired in a moment, and it is not an exaggeration to say that I am a robot, but I am really human. Huang Qiang said. Huang Yu nodded when he heard this, Huang Qiang is naturally a person, and there will be all kinds of problems with the robot.

Huang Yu and Huang Qiang have a lot of exchanges, and they already know what the so-called science and technology are. The technology of energy, which needs to be achieved with the help of external forces, is a way to seek strength from the outside, and cultivating immortals is the path to seek strength from within, which of the two is right and wrong, and it is difficult to judge which is better or worse, Huang Yu feels that both have merits, he chooses to take the road of cultivating immortals, but he will also learn from science and technology, which can be regarded as a major immortal sub-technology, and Huang Qiang now seems to be the main technology and a minor immortal.
