Lu Feng explained: "The normal Yin Soldiers' Illusion Formation should be strictly considered a 'ghost formation'. The formation soldiers it arranged are not jade figurines, wooden figurines or soul beasts. Instead, they directly use the dead as soldiers, engrave the 'dead soul pattern' on the bones of the deceased, imprison the soul of the deceased in the backbone, and temper it into weapons, and then polish it into a formation soldier with the 'ghost pattern'."

"Not only that, this formation is also extremely harsh in the choice of the dead, requiring that it must reach the level of the Earth Soul Realm before death, otherwise the strength of the soul is not enough to complete imprisonment, and it cannot be further polished into a formation soldier."

After Bai Bing understood, his expression became even more serious, "No wonder the ghostly magic array is also at the lowest level of the earth soul."

Suddenly, two masked men, one left and one right, appeared at the same time, and attacked Lu Feng and Bai Bing at the same time.

"No, their strength has improved again," Bai Bing said in horror.

Lu Feng felt the pressure from the masked formation soldiers. From the beginning, it was just the Five Elements and One Qi Realm, but now it is close to the level of the Five Elements and Five Qi Realm.

"If we drag it down, we will die here," Bai Bing struggled to fight against the masked formation soldiers. At this time, the formation soldiers no longer had to use sneak attack methods, but chose to confront each other head-on.

Even the formation soldiers of the Earth Soul Formation would never increase their strength so casually. They also increased twice in a row. The only explanation was that part of the power dispersed from the formation disappeared.

In other words, if the five people were trapped in the formation at the beginning, then at this moment, at least one or two people were dead or out.

If this formation is at the level of the Earth Soul Formation, then as the trapped person dies, the power of the formation will gradually return to the level of the Earth Soul Formation. At that time, no one will escape.

Lu Feng held Canghaixiao and swung it again and again at the weakest place of the formation soldiers, but they only left a faint trace, which could not cause substantial damage to the latter.

The strength of the Five Elements and Five Qi Realm, and the defense at the Earth Soul Realm level!

"What kind of formation level is this?" Lu Feng was shocked. He was okay to use his current methods to deal with the Five Elements Realm. He was really powerless when facing a formation soldier with a defense of the Earth Soul Realm level and still had no life.

Lu Feng knew that Lu Qian must have come to the formation, and the improvement of the formation force's strength was most likely because of her departure. The reason why she guessed to leave instead of death was because of her body's formation plate. If the death array plate shattered, Lu Feng would definitely have some perception.

Lu Feng knew Lu Qian's strength very well when he was making a formation plate for him. She must not be able to go out to fight against the formation soldiers, and she must have other means or methods.

Lu Feng was brave enough to secretly visit the battle soldiers. It was very dangerous to do this when facing unknown formation soldiers. If the opponent's soul strength reaches the level of the Earth Soul Realm, then his test would be at the least the soul would be damaged, and at the worst the soul would be suppressed and destroyed by the opponent's soul.

"Huh?" A hint of joy and surprise flashed across Lu Feng's face. The soul strength of the two formation soldiers was only the Five Elements and One Qi Realm. Lu Feng felt a familiar breath from their souls.

"Is it the Shadow Killer Beast? Fortunately, it's not a real Yin soldier," Lu Feng breathed a sigh of relief. He found that there was no soul at the Earth Soul Realm level in the formation soldiers, but the aura of the Shadow Killer Beast was attached. To be precise, the main body of the Shadow Killer Beast was divided into several parts and hidden among the various formation soldiers.

"Did you find something?" Bai Bing stopped the formation soldiers with a sword and approached Lu Feng.

"Attach the sun essence in the Yanyang crystal to the sword," Lu Feng shouted, took out a piece of Yanyang crystal with his left hand, and quickly attached the sun essence in the crystal to Canghaixiao in his right hand.

If Bai Bing shone against the land wind, he quickly attached a layer of sun essence to the long sword.

"Slay the sun's essence into it," Lu Feng did not use his powerful sword skills, but chose the same formation soldiers to constantly detour. Although they could break through their defenses with all their strength, they could not hurt the shadow killing beast inside. Only by constantly consuming the sun essence to stick to the body surface of the formation soldiers can they consume the shadow killing beast inside to death.

If the strength of the formation soldiers has not improved, they are still like that. Then using the Sun Essence to use the powerful soul skills to attack, you can indeed kill the Shadow Killer Beast's clone in one fell swoop.

Although there is not much sun essence in the Yanyang Crystal, it is enough to deal with the Shadow Killing Beast's clone.

If the shadow killer beast is intact, Lu Feng's method will inevitably be discovered, but as a clone, its own intelligence has declined. At this moment, even if it senses the erosion of the sun's essence, it is powerless.

"Sir~"

A sirloin sound like ice water pouring on the magma came from the body of the formation soldiers. The two formation soldiers melted at a speed visible to the naked eye, and the surrounding environment began to change, and a layer of darkness rolled upwards.

"Ding~"

Two crisp sounds sounded, and two pentagonal black jade were added to the original position of the formation soldiers.

Lu Feng and Bai Bing approached and picked up the five-horned black jade. The scenery in front of them changed again. The two returned to their original location. There was still Han Xin Rock around them, and the red salt beside the wall did not change at all.

Lu Feng looked at the black jade in his hand and suddenly heard Bai Bing's voice sound.

"The stone wall over there seems to have two grooves."

Bai Bing looked at the groove, then looked at the five-horned black jade in his hand, and said, "This seems to be a key. Let's try embedding it on that stone wall?"

The two put the five-horned black jade into the groove of the stone wall, and a terrible suction force came from the stone wall. The next moment, Lu Feng and Bai Bing, who had not left the black jade, were sucked into the stone wall.

Lu Feng stood firm and found that he had arrived in an independent secret room. He did not see anyone except him. There were five jade boxes in the center of the secret room.

"Congratulations on passing through the Yangyang Gate Trial Secret Realm, you can choose any prize and leave."

Lu Feng suddenly remembered such a sentence in his mind, and was shocked. He didn't know the soul thoughts left by any ancestor.

Although I have never heard of the Yangyang Sect, if I can create such an environment for the children of the sect to try, the sect will definitely not be weak. Nowadays, super forces and first-class sect Lu Feng on the mainland have heard of it, and there is no Yangyang Sect existence.

Therefore, Yangyang Men's Agent may not be this era, and may have been submerged in the long river of history until now. However, this secret trial realm has been preserved and was accidentally discovered and mistakenly recognized as a treasure land.

Lu Feng checked the jade box and found that there were complex patterns on it, which were connected from the surface of the box to the ground.

"Can you only choose one?" Lu Feng raised a smile on his lips. He didn't like to make choices. He came here for a lifetime, so he naturally wanted it all!

Although the patterns on the box are extremely complex, Lu Feng is confident that he can crack it. In order to ensure that there is no accident, Lu Feng uses purple eyes to perform the charming eye technique and begins to carefully check the structure inside the five boxes.

After some inspection, Lu Feng was sure that there was no restriction inside the box, so he immediately began to carefully decompose the patterns layer by layer, and operate the spiritual energy to dismantle them.

These may be extremely difficult for the outside world, but Lu Feng has the knowledge of array arts learned by Linglong Gu, and it is only a matter of time to unlock these jade boxes.

"Huh~ Fortunately, I didn't open a box first," Lu Feng spent more than two hours untie the patterns. He found that these patterns were secretly closely connected. Once a box was opened, the nodes in other patterns would be blocked. It would take less than a few hours to crack them.

"Look at what's hidden inside?"

Lu Feng smiled and opened the first jade box. Looking at the things hidden inside, he couldn't help but feel a little disappointed.

"menu?"

There is only a hand-painted classic with the word "recipe" in the first jade box. Lu Feng flipped it out a few randomly and recorded many ways to make and cook spiritual food, but it was not very attractive to him. Although the spiritual food recorded at the end of the book can play a certain role in the Earth Soul Realm and even the Heaven Soul Realm, the energy and time spent to reach this level are also extremely hard.

After putting away the recipe, Lu Feng was already mentally prepared when he opened the second jade box, but when he opened the second jade box, he couldn't help but feel disappointed again.

"Are you mistaken? After all, this is a very dangerous trial secret realm. Why is the reward so bad?"

Lu Feng sighed at the elixir bottle placed in the jade box. Although he didn't know much about elixirs, as a basic common sense, he could also see that the elixirs in the bottle had rotted and had lost their medicinal properties.

If he didn't understand the secret method of unzipping the sealing pattern and unfortunately chose this box, his luck would be too bad.

He casually put away the pill bottle, and Lu Feng opened the third box casually, his eyes lit up, but then he sighed again.

The bottom of the third box is empty, an ice-blue long sword is vertically in the box, and the bottom is connected to the ground.

Lu Feng wanted to pull it up, but after trying it a few times, he found that he didn't move at all. Instead, his palm was injured by the cold air coming from the sword body.

"The long sword made by Han Xin Jing Iron?"

Lu Feng was surprised. The value of this long sword was comparable to the swords of his senior brothers when he was in Qinghe Sect. It was the sword of the soul master of the Heavenly Soul Realm, and the quality can be imagined.

"What a pity, if it was a soft sword, it would be perfect," Lu Feng shook his head and used the Qinghe sword intent, exuding a creeping chill. He easily pulled up the long sword. Looking at the three words "Kanxin Sword" engraved on the sword, he couldn't help but think of Bai Bing. If she had used the White Lotus Sword Technique and this Hanxin Sword, she might not have beaten her in a short time.

"I hope the remaining two boxes can bring something useful," Lu Feng prayed for a moment, opened the fourth box, and his expression became serious in an instant. After seeing the things hidden, a smile finally appeared.

Inside the box is a knife with a sharp and cold light. The blade is only the size of a palm, and looks like a reduced version of a dagger, but it has a very beautiful texture.

"Fu Xun carved sword, Linglong treasure arc ranked ninth, cast by the Five Elements Heavenly Crystal, can transform the five elements qi on the blade. The spiritual energy consumed when laying the Five Elements Formation is reduced by 3 to 70%, and when laying the ground and heavenly Formation, the spiritual energy consumption is reduced by 1 to 30%..."
