After the green sword energy was absorbed by the sword pill, some blue marks appeared on the surface of the sword pill.

When the sword pill rotates, these green marks detach from the sword pill and then wander in Ling Feng's dantian.

Some green marks, after touching Ling Feng's Dantian barrier, were instantly integrated into Ling Feng's Dantian barrier.

Ling Feng felt a slight chill coming from his Dantian.

Under the influence of this green mark, his Dantian transformed again.

As time went by, more and more green marks were thrown out of the sword pill.

These green marks traveled along Lingfeng's meridians and were continuously absorbed by his meridians. Finally, these marks entered Lingfeng's acupoints and were also absorbed by his acupoints.

His meridians and acupoints are constantly being strengthened by the green mark.

These green marks also entered Ling Feng's mind and merged with the origin of his soul.

These green marks contain powerful sword intent and can also make Ling Feng's soul origin become more pure.

And Ling Feng's physical strength is also slowly increasing.

After a while, Ling Feng stopped practicing.

"What's wrong?"

The spirit crab asked Ling Feng. It couldn't understand why Ling Feng stopped so quickly.

Lingfeng opened his mouth and said to Ling Crab: "Although the sword energy in this lake is stronger than the sword energy in the previous pool, its strength is not very obvious, and its effect on me is limited. In the core area of ​​​​the ruins of this city, there should be

For the more powerful sword energy, we can directly enter the core area and practice in the core area, and the effect will be better!"

"That's right!"

The spirit crab glanced at the lake below and said, "Then do I still need to absorb these lake water?"

Ling Feng shook his head slightly and said: "No need for now, there may be better ones inside! There is no need for us to waste time here!"

"good!"

The spirit crab responded, then left the suspended island with Ling Feng and continued flying towards the core area of ​​the ruined city.

In the core area near the city, various powerful seals appear constantly.

Those spirit sword creatures living in the city can freely cross these restrictions, but Ling Feng and the others cannot.

Fortunately, Ling Feng has the secret technique of Lingxi Finger, which can easily unlock these restrictions.

This time, Ling Feng activated the silk scarf's true spirit secret technique, restrained his aura, and slipped in quietly.

Because he didn't want to be discovered by those spirit sword creatures and cause trouble for him.

A month later, Ling Feng and Ling Crab finally arrived at the core area of ​​the city.

The core area of ​​the city is a giant lake hundreds of miles in diameter.

The water of this lake is silver, and there are many lotus flowers growing on the lake surface. These lotus flowers are all composed of spiritual swords.

Above the lake, there is a huge whirlpool, and above the whirlpool, there is a black waterfall hanging down.

The sword intent radiated from this black waterfall almost made Ling Feng feel suffocated.

"What a strong sword spirit!"

Lingfeng looked up at the whirlpool above the giant lotus, and said to the spirit crab: "This should be the core area of ​​the city."

The spirit crab also looked at the whirlpool and said, "I wonder what is behind this whirlpool?"

"Let's go up and have a look!"

Ling Feng's eyes narrowed slightly, and then he took the spirit crab and flew towards the vortex above.

"roar!"

When Lingfeng approached the whirlpool, the space in front of him distorted, and then a silver sword dragon appeared.

This silver stegosaurus is in the form of a true dragon, with a body length of over 10,000 meters.

The aura exuding from the silver sword dragon is very strong, and it has the strength of the Great Perfection level of a king.

Ling Feng felt a little pressure on this stegosaurus.

"It seems that if you want to get in, you must deal with this stegosaurus!"

Ling Feng stretched out his hand, and the Heavenly Snake Sword appeared in his hand.

The sword art in his body was operating to the extreme, white sword seals instantly poured into the Heavenly Serpent Sword, and a fierce sword intent burst out from the Heavenly Serpent Sword.

"roar!"

The silver sword dragon felt the sword intent emanating from the Heavenly Serpent Sword, and immediately roared at Ling Feng, and then the sword dragon flew towards Ling Feng with its teeth and claws open.

Ling Feng felt that the space in front of him was distorted. The Stegosaurus, which was still far away from him, suddenly appeared in front of him.

The sharp claws of the Stegosaurus slapped towards him.

This Stegosaurus is so big that Ling Feng is like a mosquito in front of the Stegosaurus's claws.

However, although Ling Feng is small in size, the aura exuding from his body is not weak at all.

He held the Heavenly Snake Sword in his hand, and then swung it violently, shouting in his heart: "Ziyun Sword Wall!"

A large amount of purple sword energy appeared, forming a sword energy barrier in front of Ling Feng.

This sword energy barrier is in the shape of a hemisphere, protecting Ling Feng.

The stegosaurus' huge claws slapped against the sword energy barrier.

"boom!"

The sword energy barrier was broken, and Ling Feng took the opportunity to retreat.

Just after Ling Feng retreated, the sword dragon swung its tail towards Ling Feng, but it was a step slower.

"Purple Cloud Sword Dragon!"

Ling Feng used the Fusion Sword Technique to the extreme.

The rotation speed of the sword pill in Dantian increased dramatically.

A large number of sword seals were thrown out from the sword pill, and then were instilled into the Tian Serpent Sword by Ling Feng.

"Buzz!"

The light of the Heavenly Serpent Sword instantly changed from red to purple.

A large amount of purple sword energy shot out from the Heavenly Snake Sword.

These sword energy condensed into a purple sword dragon in the air.

The purple stegosaurus continued to grow and became a stegosaurus that was 10,000 meters long.

The aura emanating from the purple stegosaurus is stronger than that of the silver stegosaurus.

"Ouch!"

After the purple Stegosaurus appeared, it immediately let out a loud roar and then rushed towards the Silver Stegosaurus.

"Ouch!"

Not to be outdone, the Silver Stegosaurus immediately struggled with the Purple Stegosaurus.

Two stegosaurs with a body length of more than 10,000 meters entangled and fought in the air, erupting into bursts of terrifying energy fluctuations.

The invisible sword intent affected the silver waterfall hanging down in the whirlpool.

The silver waterfall, under the impact of the sword, spread out in the sky, turning into silver mist that spread all over the sky.

"Ouch!"

"roar!"

The two stegosaurs are equally powerful.

Although the aura of the purple stegosaurus is stronger, this is the home of the silver stegosaurus after all, and it is more familiar with the space environment here.

Ling Feng, on the other hand, stood in the void and did not continue to take action.

After a while, the purple stegosaurus opened its mouth and bit the silver stegosaurus' neck.

"Crack!"

The silver stegosaurus' neck was bitten off.

"roar!"

The purple stegosaurus let out a roar, then grabbed the silver stegosaur's head with its front paws, and then used force to crush the silver stegosaur's head.
Chapter completed!
