I Guard the Country Gate with a Centenary Body

They also want to know what is so special about this exercise.

What they didn't expect was that after hearing the price, Chu Feng said without any hesitation, "Take it yourself, this exercise belongs to me."

"Mr. Chu Feng is really rich and self-willed. You can buy [-] dark crystals if you say you want to buy them."

"This is a contestant from any country, I'm afraid I have to hesitate for a while?"

"Nonsense, do you think everyone is as rich as the old man?"

"To be honest, in the entire Dark Tower, no one has more dark crystals than the old man."

"Yeah, I was so shocked when the old man took out those monster corpses!"

After successfully paying [-] dark crystals, Chu Feng successfully exchanged for this exercise.

After lifting the restriction, he can naturally start to read the second half of the content.

Chu Feng didn't waste any time, just sat on the ground and began to delve into the content of this "Hidden Killing Art".

His comprehension is not bad. If it takes a few hours, even if he can't master this exercise, he will definitely be able to reach the level of entry.

However, at this moment, the sound of dragon chant suddenly sounded in Chu Feng's ears.

I saw Xiao Jin hovering above a pile of crystal stones, making the sound of dragon chant continuously.

Chu Xia said softly, "Dad, Xiao Jin seems to be very interested in these crystals."

Chu Feng nodded, and picked up a spar casually.

Later, he was surprised to find that these crystals were all similar to the shape of a dragon!

He turned his head, looked at the black-robed businessman, and asked, "What are these crystals? How much are they?"

The black-robed businessman immediately said: "These spars are called 'Dragon Crystals', and they will only be produced in places where real dragons live, and they contain a small amount of dragon energy."

"As for the price, it's not expensive. You only need a hundred dark crystals to exchange for one dragon crystal."

One hundred dark crystals can be exchanged?

After hearing the price, Chu Feng couldn't help being slightly taken aback.

In this way, this dragon crystal is indeed not expensive.

Thinking of this, Chu Feng immediately said: "Then give me ten coins first."

Since Xiao Jin was so eager, Chu Feng naturally would not be stingy, and directly exchanged ten dragon crystals for him.

After taking the dragon crystal, Chu Feng directly picked up one from it, like teasing a dog, and casually threw it to Xiao Jin.

Xiao Jin let out a long roar excitedly, opened the dragon's mouth directly, and swallowed this dragon crystal in one gulp!

Chapter 69 Sign-in Reward: Enlightenment Tea!

"Crack, click..."

After swallowing the dragon crystal into his mouth, Xiaojin chewed it directly, making a sound like chewing potato chips.

In the process of chewing, Xiao Jin's face showed an expression of incomparable enjoyment.

Moreover, what surprised Chu Feng even more was that during the process of devouring the dragon crystal, Xiao Jin's aura was also gradually rising.

Obviously, as the black-robed businessman said, there is a certain dragon spirit in these dragon crystals.

After devouring the dragon energy, Xiao Jin's strength will naturally increase accordingly!

In this way, these dragon crystals are not just as simple as being able to satisfy Xiaojin's appetite.

After eating the dragon crystal, the little golden dragon smacked his lips, and cast his longing eyes on Chu Feng again.

Obviously, it wasn't full yet.

After thinking about it, Chu Feng grabbed another dragon crystal and threw it towards Xiao Jin.

Without the slightest hesitation, the latter raised his head again and opened his mouth to swallow the dragon crystal!

Under Chu Feng's uninterrupted feeding, in less than 10 minutes, all the ten dragon crystals he exchanged into Xiaojin's stomach.

Until this time, Xiao Jin burped contentedly.

I have to say, this little guy's appetite is really good enough.

It took ten dragon crystals to fill its stomach.

In this way, the dragon crystal I exchanged for is really not enough.

Thinking of this, Chu Feng immediately said, "Then give me another fifty dragon crystals."

"Thanks to your patronage, there are a total of five thousand dark crystals."

With a big wave of his hand, the man in black directly put five thousand dark crystals into his cuffs.

"Old man Chu Feng is arrogant, and the five thousand dark crystals are gone."

"It's really rich and willful. This dragon crystal is bought back, and it's completely for the little golden dragon to eat as a snack!"

"Don't tell me, after eating the dragon crystal, the little golden dragon looks more energetic!"

On the other side, Chu Xia also chose a suitable weapon for himself.

To Chu Feng's surprise, the weapon Chu Xia chose was actually a gun!

A scarlet spear!

This spear, named Chiyan Spear, was exchanged for three thousand dark crystals at the black-robed merchant!

"I didn't expect that you would choose to use a long gun."

Chu Feng smiled and said, "With your character, I thought you would choose a sword or a knife."

Chu Xia smiled: "Then dad, you don't know me very well."

"When I was young, I always yearned to be a great general with a silver gun and a white horse."

"What's more, it's not unreasonable to be one inch long and one inch strong."

Chu Feng nodded: "That's true."

After squandering the dark crystals, they can naturally leave this layer.

However, at this moment, Chu Feng suddenly said, "Okay, it's getting late, or we can sleep here for the night first."

Chu Xia was slightly taken aback: "Sleep for one night?"

"But the deadline for the Dark Tongtian Tower is only three days, and tomorrow is already the last day!"

Chu Feng said indifferently, "Yeah, isn't there still one day left? There's nothing to worry about."

"Good guy, what the old man said sounds quite reasonable, but there is always something wrong."

"Let me translate it for everyone. What the old man said is that the contestants from other countries are all a bunch of rotten fish and shrimps. When I wake up tomorrow, I will overtake them all!"

"Damn it, the translation is good! Brother is a genius!"

"Hahahahaha, it is recommended that Huaqing University's Department of Translation and Translation be admitted directly!"

"If you're so good at talking, why not publish a book!"

After Chu Feng expressed his attitude, Chu Xia naturally did not choose to object.

Although he was a little worried that the time might be too late, since Chu Feng wasn't worried, he wasn't worried either.

"Brother, you don't mind if we spend the night here?"

Chu Feng turned his head, looked at the black-robed merchant, and asked with a smile.

"Please help yourself."

The black-robed businessman didn't care about this, and immediately answered.

Afterwards, Chu Feng directly took out a mattress from the Sumeru Ring, spread it on the ground, lay down directly, and soon fell asleep.

Not long after, even snores sounded in the live broadcast room.

"Good guy, the old man's sleep is really good enough, he fell asleep in a second, without ambiguity at all."

"The old man really didn't regard this black-robed businessman as an outsider, so he almost dragged him to sleep together."

"That's not true, the old man is a big customer, and it's normal to have some unspoken rules."

"Hahahahaha, the unspoken rules are okay."

…………

Long night.

Soon, the night passed.

It's another day.

Chu Feng lifted the quilt, and after stretching, he stood up directly.

The man in black still stood where he was, just like an NPC in the game.

If Chu Feng guessed correctly, this guy should not need to sleep at all.

Now that a new day has come, the most important thing is to sign in.

After feeling that he was almost awake, Chu Feng immediately said silently in his heart: "System, I want to sign in."

In the next second, the system's notification tone rang in his ears.

"Ding, congratulations to the host for successfully signing in, the current age has been reduced by one year, and the reward: Enlightenment Tea!"

Enlightenment tea?

After hearing the system reward this time, a strange look appeared in Chu Feng's eyes.

Immediately afterwards, a cup of emerald green tea, still emitting steam, appeared in Chu Feng's hands immediately.

Enlightenment tea [special props]
