The underground tunnel is winding and difficult to walk.

However, Cheng Feng has gone through it once and is familiar with the general route, so the speed is much faster than when he came here.

But even so, it will take him a long time to get to the other end of the tunnel.

Therefore, Cheng Feng combed the gains and losses of the rescue operation while on his way.

"Although there were some twists and turns in rescuing my master this time, they were all in danger."

Cheng Feng whispered, "it's the blood god sect. On the contrary, it has suffered a little heavy losses."

"First, in Shilipo, I destroyed the plan of yumiantang to capture long Aotian, so that it could not refine the 'Tianlong Guiyuan pill', which greatly delayed the healing time of Yumian Dharma protector."

"Secondly, I killed manager Pei of yumiantang and got a semi-finished ultimate mechanical puppet and a pair of Dragon Skin guards."

Cheng Feng thought: "in addition, I took the opportunity to blackmail long Aotian and got half a kilo of Tianlong blood, which not only made Tianlong lice return to the peak, but also broke through to the king level."

Cheng Feng couldn't help but take out the empty pot, open the lid and look inside.

We immediately saw that the Dragon lice was lying on the second floor of the Dragon lice hall, and five white lines had been born on its back.

"Five King level white lines?"

Cheng Feng raised his eyebrows: "it seems that the Dragon lice has reached the middle level of King level, and the dragon blood in its body has not been digested."

"Nine times out of ten, he will be able to reach the king level after he has refined and absorbed all the Tianlong blood."

"At that time, even the strong who half step into the sky will be afraid of three points."

Thinking of this, Cheng Feng's face showed a smile.

Then plug the lid of the empty pot again and put it away.

But at this time, the voice of hell came from the void pot.

"Cheng Feng, just now you used my source of fire for 16 minutes and 43 seconds."

Hell's black fire said, "you have seven hours, forty-two minutes and eight seconds left!"

Hearing this, Cheng Feng's good mood was immediately destroyed.

"Hell Heiyan, your time card is too accurate? Even seconds are used!"

Cheng Feng raised his eyebrows: "I don't think it's necessary to be so fine. Give me a few more seconds and it won't have a great impact on you."

When he was in the ancient jungle, Cheng Feng had an agreement with hell Heiyan.

The time that the other party has protected him for ten years has been replaced by ten hours of pouring the source of fire.

In other words, Cheng Feng only had ten hours to use the source of hell's black fire.

Now, it has been reduced to seven hours and more than 40 minutes.

"An agreement is an agreement and cannot be changed at will."

For Cheng Feng's request to take a few more seconds, Hellfire flatly refused.

"So stingy?"

Cheng Feng frowned: "you know, you still need me to exchange something for you in the Royal treasure house. Isn't that right?"

"Cheng Feng, one yard to one yard."

Hell's black inflammation said, "besides, I've helped you a lot this time."

This is true. In the Qianhe Island basin of the Yucang River, if it were not for the hell Heiyan, he would search the soul of the black faced Xuan sun Xuan in time, and then tell Cheng Feng the information he found.

Then maybe Cheng Feng has been exposed on Qianhe island.

"Well, just think I didn't say anything just now." Cheng Feng was speechless.

In fact, hell's black inflammation improves Cheng Feng's cultivation with the origin of fire, which can be called a super bottom card.

Although the time is a little short, use it less once.

But the effect is wonderful!

For example, this time, Cheng Feng not only killed a large number of blood god sect martial artists in a short time of more than ten minutes, but also killed Xiao Yun, one of the ten true stories of blood god sect, and the strong green robed helmsman who half stepped into the sky.

It was a great setback for the blood god religion.

At the same time, Cheng Feng also got several treasures.

First, the soul locking disc of the top Taoist instrument; Second, the defense treasure dragon turtle shield; Third, two high-level Taoist swords.

In the underground tunnel shuttle, Cheng Feng picked up a silver sword.

I saw this silver long sword. The body of the sword was silver and bright, with a layer of fine dragon patterns, just like a silver dragon.

In fact, the green robed helmsman subdued a mysterious silver dragon with the limit of nine grades and forged it with its keel and many precious materials.

The sword is still shaking violently when Cheng Feng holds it in his hand. He wants to get rid of Cheng Feng's suppression.

"Good sword, what a good sword."

Looking at the silver dragon sword, Cheng Feng couldn't help praising: "it's a pity that I'm not good at using the sword."

"And elder martial brother Jian also has the weapon 'body killing sword', which is higher than the silver dragon sword."

"In that case, I'll take you to repair the chopping magic knife!"

Cheng Feng whispered, "the damage of the cutting magic knife has been delayed for a long time. Swallowing this high-level Taoist soldier must make it return to its peak."

The chopping magic knife is connected with Cheng Feng's heart. When he hears Cheng Feng's words, he gets excited immediately.

The Dark Blade trembles and emits a lot of strange black gas.

As for the silver dragon sword, after hearing Cheng Feng's words, the struggle became more intense. He wanted to break away from Cheng Feng's repression and then run away.

But I can't get rid of it at all.

Although Cheng Feng has dissipated the origin of hell's black fire at the moment, his cultivation has fallen back to half a real dragon level.

But as the power of the real dragon broke out, it also pressed the silver dragon sword to move.

At the same time, the chopping magic knife flew spontaneously, and a large amount of strange black gas spewed from the blade, which directly shrouded the silver dragon sword.

Roar! Roar!

After the silver dragon sword was wrapped in black gas, the sword body trembled.

At the same time, there were bursts of dragon chants coming from the black air.

However, the sound of dragon chanting lasted only half a minute and weakened.

Like a silver dragon that has been cut off, it is dying as the essence of blood goes.

"Silver dragon sword's luster is dim, essence is rapidly losing."

Cheng Feng's body has a divine eye. As soon as he opened it slightly, he saw the situation of the silver dragon sword.

The silver dragon sword was wrapped by the black air, and the silver luster of the sword was rapidly dissipated and absorbed by the black air.

In just half a minute, the whole sword was dim, as if it had been buried in the soil for thousands of years, revealing the old air.

In contrast, the situation is just the opposite.

The black on the blade is thicker, just like the embodiment of the night, which makes people unconsciously ignore it.

At the same time, a strong spirit of deforestation is slowly recovering!

The killing Qi was so strong that even Cheng Feng felt a little frightened.

Once the spirit of killing and cutting is completely revived, those who are afraid of going to heaven must be afraid of it!

"What a powerful felling spirit!"

Cheng Feng was moved and said, "from this spirit of killing and cutting, I feel a crazy bully who stops killing gods and kills demons."

"Is this the real power of the magic knife?"

"Cheng Feng, the origin of cutting magic knife is extraordinary."

Nalan said, "maybe when it was in its heyday, it really killed 'demons', the real demons in the demon world!"

"True devil?"

Cheng Feng was surprised and said, "Uncle Nalan, do demons still distinguish true from false?"
