There is no doubt that the Xirong Demon Domain is an extremely dangerous place, otherwise it would not have allowed the spies sent by the Qin State before to go and never return. Therefore, before going, Cheng Yue needs to make certain preparations.

Equipment is not a problem for him, except for the dragon bone Tianguang armor that can only use the right arm armor so far, his other equipment is in extremely good condition, there is no damage that needs to be repaired, it belongs to the kind that can kill people and sell goods when you copy it.

What Cheng Yue really needs to strengthen is actually his strength, since he came back from the Demon Kingdom, despite a series of fierce battles, his realm has never improved much, and it is only the eighth peak of the Huaxi Realm.

The realm needs a certain amount of opportunity and accumulation to improve, and now it's in a hurry, the only thing Cheng Yue can do is actually work specific moves.

The battle with Nangong Mei in the Human Palace, as well as the vicious battle with Zhou Bolong afterwards, made him feel deeply, especially using the power of the true yuan mana to guide the power of the law and casting skills similar to spell attacks, he was very interested.

For him, who is still in the Celestial Transformation Realm and has no large-scale spells available, this type of spell is very suitable. It's a pity that Yun Shengmen doesn't have the law skills that can cooperate with the Heavenly Sword Splitting Slash or the Demon Arrow Blood Annihilation, and he has more laws than ordinary people, there are two kinds of them, so if he wants to get the True Yuan Law Technique that can be used, he has to develop and create it himself.

Everyone in the world knows that it is easy to follow the trend, but it is difficult to create. What's more, he still created a spell out of thin air that could be used with the power of the law, and what Cheng Yue had to do was almost the same as the sect masters, and the difficulty could be imagined.

But despite this, Cheng Yue is still full of confidence, he is an ambitious person, if he wants to become the strongest in the world, then it is necessary to surpass most people in this world, including those grandmasters! If he can't even surpass these grandmasters, then his ambition can only be an absurd, impossible joke!

Cheng Yue didn't do it behind closed doors and groped around by herself, but went to consult Nangong Mei, wanting to find a little way out of her True Yuan Law technique.

Nangong Mei was already his woman at this time, so it was naturally impossible to hide it from him, so she immediately revealed her True Yuan Law Technique and taught it to Cheng Yue.

Cheng Yue benefited a lot from this and initially understood the theoretical basis of the True Yuan Law Technique.

In the past, he attached the power of the law to the martial arts, and it seemed that the power of the laws was attached to the martial arts, but in fact, it was only a very rudimentary application of the True Yuan Law Technique.

The true element law technique is a technique that can use the true element mana to guide the law power to make various complex changes and multiply its power.

Just like Nangong Mei's "Charm and Spirit, Thousand Souls Extermination", the Netherfire that was originally just the power of pure law, after being guided by the true yuan mana, not only still has the powerful lethality brought by the previous law attributes, but its killing range and attack method have undergone earth-shaking changes!

In fact, if Cheng Yue hadn't had a divine weapon like Tai'a, he wouldn't have been able to crack Nangong Mei's Thousand Souls Extermination so easily.

"It's not simply attached to the outside, but truly integrated and complementary...... Cheng Yue sat at the desk, muttering thoughtfully, suddenly, he stretched out his palms, and each held up a kind of law, the Taiyin method in his left hand, and the life law in his right hand.

"Taiyin can seal the enemy, and life can weaken the enemy. ”

As he spoke, Cheng Yue let the power of Taiyin in his right hand form a black ice crystal, and then tried to inject the life force of his left hand into the Taiyin ice crystal.

"Shh

Cheng Yue pursed his lips, this experiment failed without accident, the density of the ice of Taiyin is extremely high, once frozen, it is difficult for foreign objects to enter.

"Then let's adjust the order!"

Cheng Yue said to himself, shook his hand and threw the ice crystal, and his left hand re-held a ball of Taiyin power that had not yet been iced.

"Enter!"

Cheng Yue snorted lightly and injected the power of life into the power of Taiyin.

This time, there were some results, under the urging of Cheng Yue, the life force dyed half of the Taiyin force red, but the power of the Taiyin was obviously very resistant to this, and the place that had just been dyed red became as black as ink in the next moment.

Cheng Yue thought for a while and said, "It seems that there is a lack of the power of reconciliation. ”

This time, he sacrificed the true yuan mana, condensed into a true yuan needle, and then used his spiritual power tentacles to control this needle to pull out a slender line of energy from the law of life, and finally used the true yuan needle to guide this line into the law of Taiyin.

The Taiyin Law did not resist and drive out the Law of Life as before, but under the guidance of the True Yuan Needle, it continued to accept the power of the Law of Life and fused with it, and finally turned into a dark red energy body.

"It works!"

Cheng Yue was overjoyed, and hurriedly tried to operate the energy body of the three forces in one, urging it to produce various changes.

"Boom!"

The next moment, the energy body exploded without warning, and a powerful shock wave flew Cheng Yue away!

"Damn, why are you so unstable?" Cheng Yue said depressedly.

Nangong Mei heard the voice and walked into the study, and when she saw his embarrassed appearance, she immediately covered her mouth and laughed gloatingly.

"You still laugh when your husband falls like this!" Cheng Yue shouted in annoyance.

Nangong Mei hurriedly went over and helped him up, pretending to be concerned and asked, "What's wrong with you?"

Cheng Yue didn't hide it and told her about the experiment he had just done.

Nangong Mei was frightened, she didn't expect Cheng Yue to really make progress, she thought that Cheng Yue was just scared and couldn't make anything.

"Do it again and I'll see. She urged.

Without saying a word, Cheng Yue repeated the process just now, and handed the unstable mixed energy to Nangong Mei for her to see.

Nangong Mei didn't dare to be careless, and hurriedly propped up the True Xi Armor, and Cheng Yue used his two layers of True Xi Armor to cover her in order to prevent her from being disfigured.

"It's unbelievable!" staring at that energy, Nangong Mei's expression was full of surprise.

Cheng Yue asked: "Do you have a way to stabilize it? Just such a little energy is so unstable, if it is a spell-level attack, won't it up first before it hurts the enemy?"

Nangong Mei thought for a while and said, "You have an even configuration of the three forces, have you tried to adjust the ratio?"

"Proportion?"

Nangong Mei didn't say it, Cheng Yue really didn't expect it.

"Yes, just like the formula of the drug, a little more of this and a little less of that one, there must be one of the most stable proportions. Nangong Mei said with a serious face.

Nangong Mei's words gave Cheng Yue a lot of inspiration, and under great joy, he couldn't help but kiss Nangong Mei's pretty face fiercely, making Nangong Mei's face full of saliva and annoyed.

"You test slowly! I've got to go beforehand. ”

Nangong Mei took out a handkerchief and wiped her face, lest Cheng Yue kiss her like this again, she didn't dare to continue to stay, and left in a hurry.

Cheng Yue didn't keep her, he was completely immersed in the experiment at this time, and he couldn't wait to find the best energy ratio in the next second.

After three days in a row, the explosion in the study of the National Teacher's Mansion continued, just like thunder, the people in the house thought that the National Teacher had an accident, and they were terrified, and the news came out quickly, making the people of Pingjing panic, Lu Wenzheng was afraid that Cheng Yue would really have an accident after learning about it, so he came to see him in person, and finally learned that he was just experimenting with magic, and couldn't help but cry and laugh.

Inevitably, the rumors spread too exaggeratedly, and Lu Wenzheng hurriedly issued an order to refute the rumors, and spread the news that Cheng Yue was experimenting with magic, and the public opinion in Pingjing City stabilized.

Today, in the midst of the national disarmament, Cheng Yue, the national teacher, is the most powerful guarantee for the snow country to resist internal and external troubles (Tianchengzi: Ahhhh

"Haha, I made it!"

Three days later, in the evening, Cheng Yue's wolf-like howl came from the study.

Nangong Mei hurriedly entered the study to check when she heard the sound, and was startled.

The study is now in ruins, the original desks and bookcases have all become charcoal or wood chips, and the books are even more unbearable, they have all turned to flying ashes. As for Cheng Yue himself, it is simply impossible to describe it in words!

He was mostly naked all over his body, wearing only a pair of crotch pants, his hair was charred black, his body was full of fire marks, his eyes were still bloodshot, and he was still hysterically dragging a black thing and laughing, if someone who didn't know saw him, he would think he had just run out of the madhouse......

"How did you become like this?" Nangong Mei's expression was like a dog in the sun.

When Cheng Yue saw her coming, he ran up without saying a word, hugged her pretty face and kissed her, shouting while kissing: "Successful for her husband! Successful for her husband!Hahaha!"

Nangong Mei really couldn't stand this, so she had to flee and leave Cheng Yue in place.

"What's wrong with her?"

Looking at Nangong Mei's back, Cheng Yue muttered to himself with a confused face.
