When he couldn't use them before, Luo Yu hadn't studied these spells carefully. He only vaguely remembered that there was such a method of attacking in a large area, which could automatically distribute forces according to the strength of the targets in the coverage area, and accurately hit each target with thunderbolts of varying strength.

In order to prevent the power of thunder from being too scattered, Luo Yu had already begun to use his mind to guide and imprison the main power of the thunder cloud within a radius of ten miles from his location, so as to ensure that he would have enough strength to deal with the alien beasts within his range at that time.

Naturally occurring thunderclouds are thin on the periphery and thick in the center, and the speed of aggregation is still within the acceptable range.

But since Luoyu had this thought, Xia Yanyin was shocked to find that the thunderclouds were compressing at a very unnatural speed!

Within a radius of ten miles, thunderclouds had doubled in thickness in a few breaths, forming layers of mountain-like clouds. The thickness of the "mountain" soon outweighed its width, and the thunderclouds were overwhelmed and soon changed shape under high pressure!

To the naked eye, the color of the clouds suddenly turned gloomy, and there was an unusually white in the leaden gray. The feeling in the mind of God changed from a faint sense of crisis to a rapid transformation into a catastrophe!

Xia Yanyin's heart was awe-inspiring, he knew that Luo Yu often borrowed the Spirit Gathering Array to increase his strength, but he didn't want him to use this method to such an extent!

Doesn't this mean that as long as Luo Yu is given enough time to gather strength, he will be invincible in the same realm? Because no matter how clever the exercises and techniques are, under the absolute power gap, they will not work.

Like all people with a strong fighting instinct, Xia Yanyin saw this situation, and subconsciously began to calculate, what should he do if he encountered such an opponent.

Although he didn't think that there would be a day when he would face each other with Luo Yubing, he just had this idea, and his heart was cold, because he couldn't imagine how he could win the battle!

Under normal circumstances, Xia Yanyin must use the fastest speed to close the distance and fight in close quarters, on the one hand, he can give full play to his advantages, and on the other hand, it is to not leave enough time for the other party to brew spells.

But this kind of general method is put on Luoyu, and it is immediately inapplicable.

If he just used ordinary spells, Luo Yu would almost always be instantaneous, and by the time he closed the distance, he might have taken several attacks. Even if he can hold up to close quarters, the advantage in martial arts fighting is unlikely to be so great that he will win, after all, Luoyu's body refining technique has improved rapidly, but his martial arts moves are difficult to win by surprise.

The reason why it is difficult to win by surprise is also very simple, that is, because Luoyu was taught by him. The two of them are too familiar with each other, if it weren't for the difference in body refining techniques, the two of them would be able to fight for three days and three nights without winning or losing......

After thinking about it again and again, Xia Yanyin could only rejoice that the two were friends and not enemies, and thought to himself, what about him!

After reading the description in the notebook, Luoyu looked at the thunderclouds in the sky that were ready to go, and his eyes showed confusion. He was pretty sure that even if he used the spells in the note, he wouldn't be able to achieve the effect described in the note.

Why is that?

Just as he was confused, a thunderbolt took advantage of the loophole, escaped from the range of the thundercloud, turned into a silver snake, and landed on the mountain next to it, causing a large number of trees to burn and catch fire.

This scene came into Luoyu's eyes, and he woke up instantly!

The thunder he used was just the most ordinary thunder, and even if he used the means in his notes to release the power of the thunder, it could only form a thunderbolt that set trees on fire in nature. To achieve a different effect, he must change the nature of the thunder!

However, according to his estimates, even if all the energy in this thundercloud was converted into the Nine Heavens Divine Thunder, it would not be able to achieve the lethality described in the notes. He immediately understood that this senior must have used some special means to make this spell exert an extraordinary effect.

Quickly flipped the notes to the front, Luo Yu carefully studied the basic exercises practiced by his predecessors, and then suddenly realized.

It turned out that this senior was also a careerist who disdained to practice the existing exercises, so he had to find another way to find his own path. He experimented and summarized countless related exercises, and incorporated his own comprehension of the Heavenly Dao of Life, and finally succeeded in creating a special thunder of his own.

This sect senior is one of the two super powerhouses of the thunder attribute that the Qingning Sect once appeared, as the deacon said in his mouth.

Ever since Luo Yu got the notes of his predecessors, he had checked the records related to him, and only then did he know that the pride in the hearts of the disciples of the Qingning Sect was actually the "devil" of the cultivation world at that time, and he was nicknamed "Thunder Prison Envoy" by the monks of the outside world.

He is not a demon who cultivates evil laws in the ordinary sense, but a righteous person who is jealous of evil and hateful, and decisively kills. It's just that what he believes in is the thunderous method of killing and stopping!

With his supernatural thunder method, coupled with his upright and violent temperament, he was stunned to kill all the crooked and evil ways at that time, including the righteous monks who did not do their jobs. Back then, the name of the "Thunder Prison Envoy" was enough to stop the baby's night cry! Of course, this had to be a baby in the cultivation world who had heard of this person's name.

This senior has no regard for the background of others, whether it is a real crooked sect, or a loose cultivator in the mountains and fields, a bad gentleman of a cultivator family, or an unscrupulous disciple of a famous righteous family, as long as anyone who is seen doing unrighteous things is seen by him, he must accept his discipline! If the bad deeds have already caused evil consequences, they must also pay the corresponding price!

His cultivation is extremely distinctive, and it is said that because of too many killings, even the usual silver-purple thunder is dyed with a layer of blood.

The book even describes that the blood-colored thunder represents justice and judgment, and as long as the person with a ghost in his heart sees the blood-colored lightning passing across the sky, he will be frightened and urinate, kowtow and apologize...... Every time Luoyu reads this, he thinks it's very funny. However, he knows very well that the reason why his predecessors were able to "run rampant" in order to uphold justice was because of his absolute strength!

Thunder naturally has the properties of deterring demons and destroying demons, but according to a cultivator's understanding, it can also derive many different traits.

For example, Luo Yu has a peaceful temperament and does not have some particularly strong likes and dislikes, plus he is not based on cultivating thunder methods, so the power he uses is not much different from the thunder in nature.

And this senior conformed to his wishes and gave full play to his upright, decisive and decisive character, so that he trained the bloody thunder, which can be said to have stimulated the swiftness and murder in the power of thunder to the extreme!

When Luo Yu understood the truth, he left behind the divine thoughts that could control the thunder clouds, and instead focused most of his energy on imitating the artistic conception of his predecessors.

In order to give full play to the effect of the spell, and also to release Ling Bingyu, no matter how much Luo Yu is not used to this intense emotion, he must also give it a try!
