Liang Feng said with a smile: "This is the magic circle handed down by my family, young master, and I have been practicing this formation since I was a child. Practice makes perfect, and it's no wonder. ”

Yao Zhenzhen shook her head lightly and said, "That's also Senior Brother Qingfeng, your magic circle talent is very good! Zhenzhen I have also practiced drawing formation patterns since I was a child, but I can never let ordinary scratch paper emit a single light." ”

"Let's start learning the 'Forward and Negative Five Elements Array'. Liang Feng urged. He has studied for a long time how to superimpose the 'positive' and 'inverse' five elements array into a 'forward and negative five element array', but there is no progress, so now he is eager to know how his predecessors designed this 'forward and negative five element array' and how to solve the problem of the huge amount of computation for the superposition of the two arrays.

At noon on the second day, Liang Feng took out a few spirit fruits and handed them to Yao Zhenzhen, and said with a smile: "Master Zhenzhen, thank you for teaching so hard. ...... Well, you eat some spirit fruits first and rest, I'll think about it for a while and then we'll go down to the fifth layer!"

“...... What do you call me?" Yao Zhenzhen took the spirit fruit and said with a smile.

"This 'positive and negative five elements array' is my master!" Liang Feng responded with a smile, and said in his heart: "It turns out that this 'positive and negative five elements array' is not like what I imagined, one positive and one retrograde superimposed to form a circle-I then superimpose it one by one, and the positive and negative five elements of each attribute - for example, the 'positive and negative gold line' will have a 'mutual growth and mutual restraint and complementarity' connection between the other positive and negative nine elements, and the positive and negative feedback is entangled, so the calculation is extremely complicated." ”

"Originally, the 'Forward and Reverse Five Elements Array' is to superimpose four pairs of positive and retrograde genera - such as 'Zhengjin Xing' and 'Reverse Gold Xing', 'Zhengmu Xing' and 'Reverse Wood Xing', 'Zhengshui Xing' and 'Reverse Water Xing', 'Zhenghuoxing' and 'Counter-Huoxing' - superimposed into four points, and then the remaining pair of positive and retrograde lines form the other two points, and then these six points form a regular octahedron!"

"Well, in this way, the calculation of the properties of the five elements of the regular octahedron is much simpler than the calculation of the properties of the five elements of the regular decagon, and the influence of the properties between them is regular - the influence between the four pairs of positive and retrograde superposition into four points is in line with the 'Fourier series', and the influence of the other two points is more complicated, but it can still be calculated by partial differentiation......"

After summarizing the learning of the 'Forward and Reverse Five Elements Array' in the middle of the night, Liang Feng took out a stack of scratch paper and deduced the calculations on the scratch paper. After a long time, he put away the manuscript paper, also took a spirit fruit and ate it slowly, and said secretly: "There is no problem with his summary......! Hahaha, hahaha, Senior Sister Zhenzhen, do you think that young master I can only learn some fur and remember a few simple calculation methods in more than a day, right?"

After resting for a while, Yao Zhenzhen asked, "Senior Brother Qingfeng, are the calculations of the 'Forward and Reverse Five Elements Array' clear?

Liang Feng smiled and said, "No need, the maintenance will never be delayed." ...... Well, let's go now...... Wait, wait for me for another hour!" He remembered that there was one more thing he hadn't prepared perfectly-when he rescued Yao Zhenzhen before, he used the 'Nether Divine Sword' to destroy the Yaksha, but it also consumed two percent of his divine sense, so now he had to add back the divine consciousness of the 'Nether Divine Sword'-

The attack of the 'Netherworld Divine Sword' is really sharp, with Liang Feng's current cultivation to control the 'Netherworld Divine Sword', he feels that if he blows hard, he can kill the monks of the third rank of Jindan in seconds, so the difference between being able to send out three attacks or four attacks is still very big - perhaps, one attack is the difference between life and death, especially when it comes to the fifth-layer palace where there are many ghosts and things.

“...... Well, his Dao Mind realm has risen greatly, and he can control greater power, so the limit of his divine consciousness should also have risen a lot. In this way, now he should use the 'Yuan Soul Bead' to quickly increase his divine consciousness, and also feed more divine consciousness to the 'Nether Divine Sword'!" he said secretly in his heart. It turned out that he only dared to feed the 'Nether Divine Sword' ninety percent of his divine consciousness, because once the divine consciousness of the 'Nether Divine Sword' surpassed his own, it was possible to get out of control.

Yao Zhenzhen looked at Liang Feng and responded, "Okay! Zhenzhen, I also have to prepare." ”

So Liang Feng set up a defensive array, and then began to use the 'Yuan Soul Beads' in the magic circle to increase his divine sense—there were nearly twenty large and small 'Yuan Soul Beads' on his body now, but they were all level six.

After running the second half of the 'Holy Demon Refining Soul Cultivation Divine Skill', all the soul elements in a little thumb-sized 'Yuan Soul Bead' were absorbed and digested, Liang Feng's own divine consciousness increased by thirty percent, and the divine consciousness of the 'Nether Divine Sword' increased by fifty percent - equivalent to the original twelve percent, which was still less than his own thirteen percent divine consciousness.

Seeing that Yao Zhenzhen outside the magic array had been prepared, and was in a daze at the three-layer light curtain of the defensive array, Liang Feng knew that she must have discovered the strangeness of this defensive array, and sighed in his heart: "It's not easy to keep a secret......

He got up and put away the defensive array flags, took out another set of trapped array flags and handed them to her together: "These are two sets of defensive arrays and trapped array flags, which should be better than your double-layer light curtain, use them for you first, and return them to me when you get out of the dungeon!"

Now that she had discovered the secret of this magic circle, and they were now close teammates, they were going to go to very dangerous places to carry out tasks, and he admired Yao Zhenzhen very much, so he felt that he still couldn't hide his secrets now, so he first lent her two sets of the latest 'Reverse Five Elements Circle' array flags.

Yao Zhenzhen fiddled with the flag a few times, and according to Liang Feng's appearance, she also set up a magic circle in the stone room-watching the three spiritual lights 'Xiu Xiu Xiu' rise extremely quickly, instantly closing into three layers of spiritual power light curtains, her eyes were full of surprise.

He also sacrificed two low-grade magic weapons that overflowed with colorful light, the 'Liulan Tianfeng Sword', and attacked the magic circle for a moment - it could only shake the second layer of light curtain violently, but it was not broken, her face was full of shock and disbelief, and she looked stunned.

Liang Feng probably understood the reason why Yao Zhenzhen was surprised—presumably because she was also proficient in the magic circle and also had a two-layer light curtain defense array, so she knew the difficulty of making a three-layer light curtain defense array.

Trying the light curtain again, Yao Zhenzhen muttered to herself, "Can it still be like this?...... How can this be?......"

Putting away the two sets of magic array flags, she shouted, "Senior Brother Qingfeng, where did you come from this magic circle?...... It's amazing, it's amazing!"

Liang Feng said with a smile: "Hey, hey, Senior Sister Zhenzhen, I got it all from the young master, do you say that the young master is powerful, is it better than your 'Brother Chen'an?" Facing Yao Zhenzhen, the young sect master of the Houtu Sect who was proficient in the magic circle, he couldn't find a suitable excuse, so he had to advance and retreat.

"You really did it?...... It's impossible, right?, I'm the first person in the Houtu Sect Technique, the first person in the magic circle, and my Tai Bozu has only created a magic circle with two layers of spiritual power light curtains!" Yao Zhenzhen looked at Liang Feng with a full gaze, as if she wanted to see something from his face.

Liang Feng had an embarrassed look on his face, and he laughed dryly and said: "Hey, hey, hey, 'Shenlongjiang back waves push front waves', it's also possible for me to surpass your Tai Bozu, young master." He just wanted to induce Yao Zhenzhen to think that he was talking big.

He said: "Whether you believe it or not, I got it from the young master, anyway, I just have this magic circle, and I have two other sets on the young master." ...... Don't say anything more, let's go down to the fifth floor as soon as possible, shall we?"

Yao Zhenzhen took a deep look at Liang Feng and responded, "Okay!"

So, the two of them assigned the array flags for maintenance, packed up their own, put away the formation flags at the entrance of the stone chamber and walked out.

Walking to the stone pavilion in the middle hall, looking at the shining spiritual light of the floor tile teleportation array, Liang Feng's heart moved, and he took out a stack of spirit runes and handed it to Yao Zhenzhen: "This 'Tianzun Vajra Fu' has four layers of defensive light curtains, which should be better than yours, and the speed of stimulation is very fast." When we get out of the circle, we need to activate this rune defense immediately. ”

“...... Okay!" Yao Zhenzhen took the spirit talisman and looked at Liang Feng deeply. Then the two of them stepped into the floor tile teleportation array at the same time—

When his head was dizzy and he seemed to wake up immediately, Liang Feng felt as if his body was immersed in ice water, and the chill was deep to the bone.

In an instant, a four-layer 'Tianzun Vajra Talisman' was activated, and he heard the sound of a sharp weapon breaking through the air, although he hadn't seen the situation in front of him clearly, he immediately threw out a few array flags and shouted: "Get up!"

"Puff puff!" "Boom Boom" "Fluff Puff!"

First, there was the sound of a series of spiritual runes' spiritual power shields bursting, followed by the sound of the spiritual power light curtain of the magic circle rising, and almost at the same time, it was the sound of a fierce attack hitting the light curtain of the defensive array.

Liang Feng finally saw the situation in front of him clearly—outside the magic circle, four black and white impermanence stood in a row, and they were attacking the defensive magic circle with two black lights and two white lights. There was also a purple ghost zombie standing next to the two white impermanences, and the corpse hands of the two zombies exploded, and they hit the light curtain of the third layer of the magic circle that had already violently shaken - with a 'peng' sound, the three layers of the light curtain of the magic circle were all shattered.

"Dangdangdang! Click!" There were several violent collisions, and the inferior defensive magic weapon 'Green Dragon Pattern Armor' in front of Liang Feng shattered into several pieces and fell to the ground.

Liang Feng's face changed, and he shouted: "Kill!" The fireballs of the 'Sun Devouring Soul Sword' and the 'Four Bursting Flame Talismans', and the golden light spiritual power swords of the 'Four Spirit Golden Sword Talismans' roared towards the two most ferocious Bai Impermanences-

Beside him, Yao Zhenzhen also shouted, and the two colored lights of the 'Liulan Tianfeng Sword' met the two black lights of the two black impermanent envoys, and at the same time, a cluster of two golden light spiritual power swords also shot out.

'Xiu Xiu Xiu' three times, after Liang Feng and Yao Zhenzhen resisted all the attacks of the four black and white impermanence, the light curtain of the magic circle finally rose and closed again.

Seeing that the magic circle was still closed under the attack of the two purple zombies, Yao Zhenzhen breathed a sigh of relief, and said to Liang Feng: "Senior brother, what should we do now? Although they can't help us for the time being, we can't kill the enemy." If this stalemate continues, we ...... We're going to die of exhaustion......"
