Return the same route.

When Shi Feng returned, Tie Zhan and others were still practicing. Relying on the top-grade earth beads, their cultivation speed was indeed amazingly fast, especially Qiu Yeyu showed talent beyond them. He actually reached the peak of a seventh-grade martial artist in just over a day, just one step away from an eighth-grade martial artist.

Others also have their own improvements.

However, Iron Battle, who had just broken through for a while, seemed to be enlightened, had actually practiced so fast than before. After a significant leap in the realm of the ninth-grade martial artist, Shi Feng judged that it was probably not long before Iron Battle could enter the realm of the Martial Master.

"Shi Feng is back!"

The first person to discover Shi Feng’s return was the autumn leaves rain.

She was always worried about Shi Feng, which led to not fully concentrating her cultivation. Now, she subconsciously regarded Shi Feng as her dependence.

The others woke up then.

"Fortunately it's Brother Shi Feng. If it were someone else, we would probably be in danger." Tie Zhan said with a little fear.

"This place is special. It has been searched by countless people and beasts. No one will come again, so it is correct for you to practice with peace of mind." Shi Feng said with a smile.

Tie Zhan nodded, changed the topic and said, "Has the Blood Yang Crystal been obtained?"

Shi Feng took out two blood Yang crystals.

"It's so big!" Tie Zhan shouted in a low voice.

Each piece of blood yang crystal is the size of a human head, which is a rare treasure. The hole under the stone tablet can occasionally accommodate such a sized blood yang crystal, which is very suitable for the requirements.

With the Blood Yang Crystal, the crowd was excited again.

They gathered in front of the stone tablet.

When I saw those words again, Shi Feng still felt like a peerless strong man was hidden in the stone tablet. Every stroke seemed to contain infinite power, intimidating others.

Shi Feng stared at him, and he had the urge to go deeper.

He tried hard to restrain this impulse.

For things like this, the Eight Desolate Refining Divine Cauldron once warned that if it were not for the very high level, do not want to go deeper, as that would be dangerous.

The soul may be wiped out by someone invisibly.

"Brother Tie, Ye Yu, you all retreat." Shi Feng said.

"You have to be careful." Qiu Yeyu said with concern.

Shi Feng nodded with a smile.

Under normal circumstances, there will be no accidents. If there is an accident, it is basically impossible to survive, so this action is also extremely dangerous.

Iron Zhan and others retreated.

"Gudong!"

Shi Feng swallowed a mouthful of dry saliva, and it was fake to say that he was not nervous. The simple handwriting on the stone tablet contained infinite power. It was probably released and could destroy a mountain of ten thousand meters. This is often the case when adventures to find treasures, life and death are in the forefront.

His eyes closed slightly, trying hard to calm himself down.

At this time, he will not retreat.

Two blood Yang crystals were selected, and Shi Feng slowly put them into the hole under the stone tablet's handwriting.

"Bang!"

When the blood Yang Crystal was put in, everyone was suffocated.

At this moment, there was no sound here, and even the heartbeat stopped. Everyone stared at the stone tablet, especially the place where the Blood Yang Crystal was placed.

Time passes by little by little.

No reaction.

Shi Feng and others couldn't help but wonder, was this a joke or was it put in the wrong place, and shouldn't be put here, why didn't there be any response?

Seeing this, Shi Feng tried hard to keep his mood stable. He stepped back first and watched quietly.

Just as they were considering whether they were looking for other places of blood Yang crystals, they saw the handwriting on the stone tablet suddenly burst into bright light.

A white light began to flow from the first word and the first stroke.

Before passing through a place, a sharp sword energy was sucking and spitting, as if it was about to leave the stone tablet and fly out, and the oppressing Shi Feng and others were about to suffocate.

When the white light reaches the last word and the last stroke, it turns into the hole below.

"boom!"

The blood yang crystal also exploded.

Countless fragments merged into the stone tablet, and the holes were filled again. Then the underground ancient city behind it shook violently, and a huge protective force appeared on the surface.

"This power begins to weaken!" Tie Zhan said in surprise.

Shi Feng also felt that the guardian power was weakening at an astonishing speed, and this made him more deeply realize the horror of the guardian power.

As the protection power weakens, the fonts on the stone tablet gradually fade, as if they may melt at any time.

Rumble!

The vibration continued, and the underground ancient city was shaking slightly.

The guardian power gradually could be seen from the original thickness of dozens of meters to a few meters, and finally to a few centimeters, and then it stopped completely.

On the other hand, the handwriting on the stone tablet completely disappeared.

"It has not completely disappeared, the guardian power is still there." Iron Battle Road.

"It should be very weak." Xiao Qi said.

They walked forward and went to check. Shi Feng came to the stone tablet. He tilted his head and looked at the stone tablet. He always felt that it was not an ordinary thing.

This stone tablet seems to contain infinite mystery.

It should be a rare treasure. As he thought so, he reached out to take out the purple lotus divine water in the divine cauldron. Since it was a treasure, he would give it to the purple lotus divine water.

Shi Feng directly slapped the Purple Lotus Divine Water on the stone tablet.

The next moment, a shocking fighting spirit came from the stone tablet, as if a peerless strong man was hiding it, and at this time he released a huge fighting spirit.

This scared Tie Zhan and others so much that they quickly retreated, thinking something was going to happen.

Shi Feng also took a few steps back, staring at the Purple Lotus Divine Water.

"I'm looking at how powerful you are." Shi Feng stared at the Purple Lotus Divine Water to see what it would happen.

The Purple Lotus Divine Water is indeed powerful and penetrates directly.

There seems to be some mystery inside the stele, and it actually fought fiercely, causing the stele to shake.

"Look, that's sword energy!"

"Who actually left a sword energy inside and was immortal."

"It was left at least three thousand years ago."

"What kind of power is the sword energy left for three thousand years and will never be destroyed? What kind of power is this sword energy?"

Shi Feng recalled what the Eight Desolate Refining Divine Cauldron once said in his mind.

If a person surpasses the Martial Saint and reaches an extremely high level, he can seal his power in one place, immortal for thousands of years, and has a huge power. The life-saving trump card of some big families is that the supreme power left by his ancestors in his family. Once released, he can split the mountains with one sword, making the heaven and earth pale.

This sword energy has obviously reached that level.

Even such a terrible power is completely defeated in front of the Purple Lotus Divine Water. This kind of retreat is different from a normal retreat. It is refined by the Purple Lotus Divine Water. To put it simply, it is eaten by the inner Purple Lotus Divine Water.

It's indeed a mess.

A rare treasure, you can eat it!

Beast shadow demon soul, you eat it!

Now, even the power of sword energy can be refined and devoured to become your power.

The purple lotus divine water after the evolution of the purple lotus divine mud has not yet reached its ultimate state. Once it is completed, what kind of existence will it be? At least it is even more strange than the Lightning Silver Wolf.

Finally, everything was refined in front of the Purple Lotus Divine Water.

The stone tablet, sword energy, or other magical things inside were all refined and there was no residue left. Shi Feng took it back.

"Shi Feng, what is that?" Ou Qinglong couldn't help asking.

Tie Zhan turned his head and shouted, "Don't ask what you shouldn't ask."

Ou Qinglong was stunned for a moment, then suddenly realized and smiled dryly, "Secret, yes, everyone has a secret, we must respect each other."

Seeing this, Shi Feng put away the Purple Lotus Divine Water.

He didn't want to say it, because he couldn't explain what the Purple Lotus Divine Water was. This name was all given by him.

"The guardian power of the ancient city is already very weak. Everyone should be able to break it when they work hard." Shi Feng said.

"I'll try it!"

Ou Qinglong was a powerful soldier and rushed out first.

He had just broken through to the seventh-grade martial artist for a few days and was about to show his strength, so he swung his giant sword and slashed hard at the guardian power.
