The Grand Canyon is in the highlands of northwestern Arizona, cut by the Colorado River, and is a sight to behold.

Xia Fei built a tent on the side of a tributary of the Colorado River, lit a fire, and poured seven or eight boxes of canned food into the pot and made a pot of stew.

Since taking the cell activation potion, Xia Fei's food has increased day by day, and the muscle lines on his body have become more and more obvious.

The wound on his leg healed ten times faster than the average person, but it was still painful to walk.

Xia Fei devoured a pot of stew, picked up a bottle of mineral water and drank it all.

He wiped his mouth, took out a cigarette from his arms and lit it, and swallowed a big gulp, "Ghost, let's start cultivating now." ”

The ghost looked at the wound on Xia Fei's leg that was still oozing blood, and said a little worriedly: "Let's talk about it tomorrow, the injury on your leg is not healed yet." ”

"It's okay, I can hold on." Xia Fei said firmly.

Yesterday's fierce battle inspired Xia Fei's strong enterprising spirit, without strength, even the basic conditions for survival could not be guaranteed.

Ghost Shadow thought for a while, "I'll teach you the [Thorn] chapter in [Shadow Moon], when you killed those two people yesterday, the position of the knife was wrong, and it was still a lot away from the best entry point, if it weren't for the fact that this [Golden Spike] was sharp enough, I'm afraid you would have to make up for a few more knives." ”

"The so-called hidden killer, to put it bluntly, is two things, one is hidden and the other is killing, you have learned a little, it's time to learn how to kill."

Xia Fei frowned, "The Hidden Killing Technique is to kill a single target, what if it is besieged?" ”

The ghost laughed, "Who said that the Hidden Killing Technique can only kill one person? Your ability is speed, and your speed is combined with the deadly [Thorn] technique, which is a perfect match, assassinating one person is a fatal stab, and when you face a hundred people, give each person a stab! ”

Xia Fei listened to the ghost's words and thought for a long time, he stood up and threw the cigarette butt into the river, watching it float away quickly, "I understand, as long as the knife is a deadly knife, as long as the knife is a deadly knife, facing one person is no different from facing a hundred people, if necessary, assassination can also become open killing!" ”

"You're right, but now is not the time to cultivate [Thorn], take out that [Fire Dragon Thousand Flames]." The ghost said with a smile.

Xia Fei carefully took out this strange plant from the safe, [Fire Dragon Thousand Flames] exists in a smart plant growth container, this container can imitate the temperature and humidity that is most suitable for plant growth, even the composition of sunlight and atmosphere, and even the air pressure can be intelligently adjusted according to the needs of the plant.

Plants can be kept in such a box for a hundred years without wilting, and the value of this container alone is more than 200,000 star coins.

"Now you should tell me what this thing does, right? After spending so many star coins, I just hope that it is really worth the price, how can I improve it to the galaxy level after taking this thing. Xia Fei placed the [Fire Dragon Thousand Flames] and the refining utensils neatly one by one, and asked.

"This plant doesn't increase your speed level." The ghost said slowly.

"What!" Xia Fei was stunned suddenly, so he fainted, "Nine million star coins!" Spending so much money on this thing can't even level up! You're fine with your brain! ”

"What are you anxious about?" The ghost muttered, "Although this thing can't increase your speed level, it can increase your nerve reaction rate. ”

"When you're running at high speed, if there's a lot of obstacles in front of you and your nerves aren't fast enough, you need to reduce your speed to get through those obstacles and you can't keep going at full speed."

"This [Fire Dragon Thousand Flames] can greatly increase your nerve reaction speed when traveling at high speed, which is very helpful to you."

Nerve sensitivity is an important indicator of a fighter's combat effectiveness, and in battle, any slight difference is likely to lead to a completely different outcome.

Martial arts in the world, only fast is not broken!

Not only is it fast, but it also needs to be fast!

All the top fighters have far more sensitivity than ordinary people, and lightning speed of reaction.

Xia Fei didn't say anything more, any medicinal herb that can increase the reaction speed is sky-high, and it is hard to find, although this [Fire Dragon Thousand Flames] is expensive, but with the functions it provides, it is completely worthy of this price.

In order to be on the safe side, Ghost Shadow first used an analyzer to measure the drug residue in Xia Fei's body.

The mixing of different drugs can easily trigger a chain reaction, Xia Fei had just taken the cell active potion two days ago, and he had to wait until the medicine was completely absorbed by the body before he could take the next batch of medicine.

"There is still a little residue, it is estimated that it should be fine in a few hours, you first purify this [Fire Dragon Thousand Flames], and then take it at night." The ghost said.

Xia Fei nodded, gently pressed the code, and opened the plant storage.

A fragrant smell came to the nostrils and was refreshing, and in a moment, the whole valley was filled with this strange scent.

Fiery red rhizomes, fiery red leaves, fiery red flowers.

This [Fire Dragon Thousand Flames] is like a raging flame, and the beauty makes people's hearts palpitate.

The dragon Thousand Flames is not a plant on Earth, and is not adapted to the air pressure and air composition of Earth, and will quickly wither once exposed.

Xia Fei did not slack off in the slightest, and sent the entire plant into the medicine refining vessel as quickly as possible.

The alchemy vessel shook slightly, and a few minutes later, a bottle of bright red liquid arrived in Xia Fei's hand.

The blood is bright red, and there is a warm feeling in the hand.

"[Fire Dragon Thousand Flames] doesn't need to be combined with any medicine, just take it directly, take advantage of this time and I'll hand over the [Thorn] mental formula to you first." The ghost said.

……

At night, the stars are shining brightly and the canyon is silent.

At night, the surrounding mountain walls take on a completely different color from the daytime, and you will be amazed by the wonders of nature.

Xia Fei had already memorized the [Thorn] mantra, and now he was waiting for the drug residue in his body to dissipate, so that he could take the juice of [Fire Dragon Thousand Flames].

After a long night of unintentional sleep, Xia Fei simply put on a virtual helmet and logged in to the interstellar Internet.

As soon as I landed, I saw Avril's pink letter.

"Yesterday I finally went to the interstellar playground, it's so fun, if you promise to help me write poetry, I'll take you there, how about it?"

Belch...

Xia Fei was speechless, this girl was too childish, "Yesterday I was chased and killed, and I stabbed myself, if you don't bother me, I'll thank God." ”

Avril's email is different, it doesn't appear in the mail system, but directly incarnates a small pink envelope, flashing in the virtual system, flashing, if you don't look at it all the time, it will keep flashing.

"Enter the email system and block Avril." Xia Fei commanded to the intelligent computer.

"Sorry, the other party's customer level is unknown, and there is no permission to block it." The virtual system of the computer said coldly.

"Can't be blocked! Why? ”

"The level of authority is insufficient."

"Inquiry, Avril."

"Sorry, I can't query due to insufficient permissions."

Xia Fei was completely speechless, the mail system of the Star Network is really weird, and it is impossible to receive emails if you don't want to.

At this time, the ghost suddenly appeared and said to Xia Fei: "When the time is up, you can now take the juice of the Fire Dragon Thousand Flames." ”

Xia Fei nodded, "Do you know why the email system can't block a person's email?" ”

"I don't know." The ghost smiled evilly and said, "I just know that it might hurt a little when you take the [Fire Dragon Thousand Flames] juice later. ”

Xia Fei's heart tightened, and a bad premonition rose.
