Zhang Hong opened the system mall.

Zhang Hong found that due to the abundance of materials, many spirit weapons and spirit arrays in the system mall can be unlocked and refined.

Many high-grade spirit weapons and spirit arrays can also be unlocked.

Seeing this situation, Zhang Hong was not polite, and even sat down in this secret realm.

Zhang Hong opened the system array furnace and immediately began to condense the spirit array.

With a top-grade spirit jade, Zhang Hong can refine a top-grade spirit array.

Regarding Zhang Hong's actions, the old man and Tang Xiaoyue didn't have much curiosity.

The old man just took care of himself and began to refine his elixir.

Tang Xiaoyue was bored on the side.

Zhang Hong refined the formation and completely entrusted it to the system.

Zhang Hong doesn't need to worry about so many things.

After about three or five hours, the four powerful spirit arrays were all successfully refined.

These four spirit arrays are the Heavenly Waterfall Flowing Fire Array, the Blue Water Heavenly Prison Array, the Hundred Refining Jinsha Great Sword Array, and the Wutu Open Tomb Burial Array.

It can be said that these spirit arrays are actually upgraded versions of the magic array.

It's just that Zhang Hong replaced the magic jade with the spirit jade.

Now that the formation has been formed, Zhang Hong is also excited.

With these spirit arrays, Zhang Hong will only be an invincible existence when he walks on this Guizang continent in the future.

At that time, in the entire Guizang Continent, no one will be Zhang Hong's opponent.

Thinking of these, Zhang Hong's heart was a little fluttering.

Zhang Hong condensed the spirit array, and he also wanted to go somewhere to try the power of his spirit array.

At this moment, Zhang Hong actually heard two coughs from the old man.

"Grandpa, grandpa, what's wrong with you. Tang Xiaoyue snuggled up to the old man's side, patted the old man's back, and asked with great concern.

"It seems that Grandpa's time is running out!" the old man shook his head and sighed.

Zhang Hong saw the old man like this, and he also supported the system to scan the old man's symptoms.

Soon, the system actually gave a rescue plan.

"Master, there is a ghost bug Gu on this person's body, the ghost bug Gu is in the body, if it can't be expelled, its own essence and blood will continue to be sucked by the ghost bug Gu, and the body will never recover, the human body has no essence and blood, it is difficult for him to survive, if this old man has not cultivated to the realm of transforming into gods, I am afraid that he has already died under this ghost worm Gu. The system said.

"Is there a way to restrain the ghost worm Gu?" Zhang Hong asked.

"The master is an alchemist, and he only needs to condense a Thunder Blood Extinguishing Gu Pill to save this old man's life. The system said.

Hearing this, Zhang Hong's heart moved, and a Thunder Blood Extinguishing Pill immediately appeared in the system mall.

The pill recipe of the Thunder Blood Extinguishing Gu Pill is a medium-grade pill.

Because the materials are sufficient, Zhang Hong can purchase this pill to condense the pill.

Zhang Hong smiled, and walked towards the old man and Tang Xiaoyue.

At this time, the old man had already had luck suppressing the ghost cockroach Gu in his body, but his face, which was originally described as withered, became more and more ugly.

"Brother Zhang Hong, my grandfather said that his time is running out, if grandpa really goes here, then what should I do!" Tang Xiaoyue suddenly cried.

"Xiaoyue, grandpa is really afraid that he won't have a few days to live, if grandpa really goes, I'm afraid that you will stay here in the future and return to the Tibetan continent. As the old man spoke, he let out a long sigh and continued: "Actually, there is nothing wrong with staying here in the Guizang Continent, at least there are not as many disputes in the Shenghan Continent here. ”

"Grandpa, you'll be fine, you'll definitely be fine!" Tang Xiaoyue said hurriedly.

"What's the situation with grandpa, grandpa knows, grandpa is really not good, that Gu thing is extremely weird, if I can't kill it, I will eventually die, now this Gu thing is becoming more and more violent in my body, I feel that I am going to die. The old man said.

"Grandpa, you'll be fine!" Tang Xiaoyue shouted.

"Yes, old man, you must be fine!" Zhang Hong had already walked over and said.

"Boy, I know what I'm doing. As the old man spoke, he sighed faintly, and said: "Actually, the old man, my biggest instinct is to look at people's faces, I know, your kid is a kind-hearted person, so I think if I leave, I hope you kid can help me take care of my granddaughter." ”

"Old man, I said, you must be fine. Zhang Hong said.

"Boy, what do you mean by that?" the old man suddenly opened his eyes and looked at Zhang Hong.

"Actually, there is nothing special about it, I just think that the old man's illness is actually not so easy to solve. Zhang Hong said.

When the old man heard this, he couldn't help coughing twice.

"Boy, just you can help me heal!" the old man shook his head, just thinking that Zhang Hong was talking nonsense.

In the eyes of the old man, the Guizang Continent where Zhang Hong is located is just a low-level plane, in such a plane, even if Zhang Hong is an alchemist and knows pharmacology, there is no way to help him get rid of the pain on his body.

"Of course, the reason why the old man's body is like this is only because there is a ghost cockroach Gu attached to his body, this kind of ghost cockroach Gu parasitizes on the human body and sucks people's essence and blood for a living, which is also the reason why the old man's body is so thin. Zhang Hong said.

"Boy, you....... You can actually see the Gu things in my body?" the old man suddenly became excited when he heard this.

"Isn't it a ghost worm?" Zhang Hong said.

"You're right, the Gu thing on my body is indeed a ghost Gu. The old man nodded, looked at Zhang Hong again, and said: "This kind of ghost bug Gu is parasitic in the human body, it seems to be invisible, there is no way to get rid of it, I have traveled to more than a dozen continents, found more than a dozen methods, and finally failed to get rid of this ghost bug Gu." ”

The old man couldn't help but sigh when he thought of the ghost cockroach Gu in his body and the sins he had suffered over the years.

"Actually, to get rid of this ghost worm Gu, you only need to swallow one pill. Zhang Hong said.

"What elixir, what elixir?" asked the old man.

"The name of this elixir is Thunder Blood Extinguishing Gu Pill!" Zhang Hong said.

"Thunder Blood Extinguishing Gu Pill?" the old man was shocked when he heard this.

"The old man also knows about this Thunder Blood Extinguishing Gu Pill?" Zhang Hong asked.

"Of course I know, this Thunder Blood Extinguishing Gu Pill is known as the Gu Killer Buster, but it's a pity that this Thunder Blood Extinguishing Gu Pill is only recorded in some classics, but the real Dan Fang has long been lost. The old man said.

"I know this Thunder Blood Destroying Gu Dan's formula!" Zhang Hong said.

"What, do you know the pill recipe for the Thunder Blood Killing Gu Pill?" the old man couldn't help but be surprised when he heard this.

"Of course, the Gu extinguishing principle of this Thunder Blood Extinguishing Gu Pill is to use the generation of a ball of thunder essence blood in the body, and the Gu thing in the body will come to devour it when it smells this ball of thunder essence blood, as long as the Gu thing swallows this ball of thunder essence blood, it can attract mental power and detonate this ball of thunder essence blood, so as to bombard the Gu thing lurking in the body. Zhang Hong said.

"Boy, you're right, this is the principle of the Thunder Blood Killing Gu Pill, at the beginning, I had seen the record of the Thunder Blood Killing Gu Pill in an ancient book, but it's a pity that I searched for more than a dozen continents, but I never found this Thunder Blood Killing Gu Pill. The old man said.

"Old man, don't worry, I have collected a lot of spiritual materials on my body, and I have collected a lot of materials in the treasure house just now, which is just enough to refine the Thunder Blood Extinguishing Gu Pill, so I will help the old man refine the Thunder Blood Extinguishing Gu Pill. Zhang Hong said.
