The next morning, there was a knock on the door on time outside the hospital.
Lu Heng collected the gray Dou Qi wandering inside his body and turned over to lie down.
Standing outside the door is Tang Huo'er.
Today she changed into a tight-fitting fiery red soft armor, her long hair was tied into a neat high ponytail, and a silver-patterned belt was tied around her waist, outlining her narrow waist.
Her long and straight legs were wrapped in deerskin boots, and her whole person exuded a heroic spirit.
Tang Huo'er was standing outside the threshold holding a heavy Rosewood box in his hand.
"Lu Heng Brother, Yao Cai My dad has prepared everything, three servings."
Tang Huo'er lifted the box upwards.
Lu Heng took the wooden box and weighed it.
"Valley Master Tang is really thorough in his work."
Then, the two passed through several heavily guarded corridors and came to a natural grotto in Red Cloud Peak Back Mountain.
A spacious alchemy room was opened deep in the grotto.
The surrounding walls are all made of heat-absorbing ink patterns Obsidian, and the surface is engraved with complex solid element formation patterns. There is a cool fragrance of vegetation floating in the air, which just neutralizes the heat coming from the ground.
Tang Zhen was already standing on the high platform in the center of the stone room.
He changed into a loose dark red robe, with his sleeves rolled up, and he stood up straight.
Seeing Lu Heng enter the door, Tang Zhen quickly came forward and hugged his fists.
"Little friend Lu, I have a favor for you today."
Lu Heng Put the Rosewood box on the stone platform, turn over and open the heavy box lid.
Dozens of Cold Jade small boxes are neatly stacked in the box, and various rare Fire Attribute and high-end Yao Cai exude a warm brilliance.
The most eye-catching one is a fruit the size of a baby's palm, dark red in color and covered with natural thunder patterns.
That is the main ingredient for refining Fire Bodhi Pill, Earth Vein Thunderfire Spirit Fruit.
Lu Heng checked the year and quality of Yao Cai and confirmed that there were no errors.
He sat cross-legged on the high-end soft futon in front of the stone platform and looked up at Tang Zhen.
"To refine Fire Bodhi Pill and Valley Master Tang, you only need to maintain the stable output of Nine Dragon Thunder Gang Fire. The rest of the steps of refining, fusing, and making elixirs are all left to me."
Tang Zhen straightened his sleeves and said seriously:
"In that case, I will fully cooperate with you."
He flipped his backhand, and a cluster of silver-white flames suddenly appeared in his palm.
A fine electric glow danced inside the flame, mixed with a faint muffled sound like a dragon's roar. The heat wave mixed with the thunder energy spread out, roasting the Obsidian on the surrounding walls to a sizzling sound.
This is Nine Dragon Thunder Gang Fire ranked twelfth among Heavenly Flame Ranking.
Tang Zhen turned to look at the red-armored girl standing aside, her tone became much more serious:
"Huo'er, retreat to the first formation gate outside the stone chamber and guard. In the next three days, anyone who approaches the forbidden area will be shot without mercy."
Tang Huo'er originally wanted to stay close and watch how Lu Heng operated, but after hearing his father's stern instructions, he had to curl his lips.
She lowered her head and patted the dust on her leather armor, and whispered:
"Just leave. What's so bad about it? It's not like I've never seen Heavenly Flames."
She walked towards the heavy stone door, the silver belt around her waist swaying slightly with her steps, and her two slender legs looked particularly well-proportioned under the long boots.
When she reached the stone door, she turned around and raised her chin towards Lu Heng:
"Brother Lu Heng, this is the wealth I have saved up with all my life. You must take it easy."
Lu Heng nodded and said:
"Don't worry, nothing will go wrong."
The heavy Obsidian door rolled shut, the outer isolation array was in full operation, and the stone room became completely quiet.
Lu Heng The sleeves of the robe were flicked, and the dark red Myriad Beast Cauldron fell on the center of the stone platform.
The medicine cauldron was heavy and made a dull sound when it hit the ground. The totems of beasts carved on the cauldron shone slightly in the heat wave.
"Valley Master Tang, pour 30% of the fire source into the cauldron and warm the cauldron first."
Lu Heng rolled up his sleeves and ordered.
Tang Zhen didn't hesitate at all. He opened his five fingers slightly, and the silver-white thunder fire in his palm turned into a line of fire, which went straight into the fire hole at the bottom of Myriad Beast Cauldron.
The temperature inside the cauldron suddenly rose.
Nine Dragon Thunder Gang Fire has extremely strong violent thunder properties. For an ordinary alchemist, just suppressing the violent vibrations in the flames would take most of the effort, and it is impossible to accurately control the temperature of the medicine.
But Lu Heng placed his palm against the tripod's ears, and Mid-Spirit Realm's peak soul power was fully unleashed. The gray-white Chaos Dou Qi penetrated along the tripod's body, forcibly smoothing out the jumping thunder.
Tang Zhen The palms of his hands trembled slightly, and his heart stirred up.
As the owner of Nine Dragon Thunder Gang Fire, he knows the wild nature of Heavenly Flames best.
But under the suppression of Lu Heng's soul perception, the thunder fire was as docile as cotton that had lost its moisture, and even the originally sharp thunder became subtle and long.
"At this level of Soul Manipulation, even if several elders of Pill Tower take action personally, I'm afraid they may not be able to do it so easily."
Tang Zhen secretly calmed down, and the Dou Qi output in his body became more cautious and regular, for fear that his own rhythm would mess up the overall situation of Lu Heng.
Half an hour passed.
The medicine tripod is completely red and has even heat.
Lu Heng raised his left hand, and Earth Vein Thunderfire Spirit Fruit in the stone box flew into the air.
"Fall."
Spirit Fruit fell into the cauldron, and Nine Dragon Thunder Gang Fire instantly enveloped it.
During the interplay of thunder and fire, the peel quickly burned and peeled off, revealing the pith that was as sticky as red jade inside.
Lu Heng is concentrating on it, and the Green Lotus Core Flame and Sea Heart Flame in the body are quietly running throughout the meridians, secretly mediating the slight deviations in the heat in every inch of the cauldron.
In the world of alchemists, the slightest deviation will turn it into ashes.
Ordinary refining methods, using fierce fire to attack, can produce elixirs, but the elixir energy is dry and strong, which will inevitably damage the lungs and meridians of the person taking the medicine.
Since he had received the great benefits of Burning Flame Valley's Heavenly Flame Melt Abyss, he naturally wanted to make this elixir perfect.
Lu Heng flicks his fingertips, and dozens of auxiliary Yao Cai fall into the cauldron in sequence.
Green Ganoderma, Bai Lie Grass, Red Marrow Crystal...
Each rare Yao Cai was burned by silver-white thunder fire to remove impurities, and condensed into drops of rich medicinal liquid of different colors.
Time passes quietly.
After the first day, all the main medicines and auxiliary medicines were refined and turned into thirty-six groups of various colored medicines suspended in the cauldron.
Tang Zhen had fine beads of sweat on his forehead.
Continuously maintaining the high-intensity output of Heavenly Flames for a full twenty-four hours, even if he was Dou Zun expert, the movement of Dou Qi in the body began to have a slight blockage.
"Valley Master Tang, hold on Heart Fire, then start Pill Fusion."
Lu Heng's voice came out calmly.
He turned over his hand and took out a Sixth-Grade Energy Recovery Pill and stuffed it into his mouth. The speed of Five Spirits Chaos Art in his body increased.
Yin-Yang Twin Fish is swimming in Qi Vortex, and the Fire-Attribute Energy free between heaven and earth continuously flows into his meridians, replenishing the energy and energy that have been consumed for a long time.
It was early morning on the third day.
The thirty-six pills of medicinal liquid in the cauldron were finally completely integrated into one place under the squeeze of Lu Heng's huge soul power.
A ball of dark red jelly the size of a fist slowly rotated.
As Nine Dragon Thunder Gang Fire continued to be tempered, the gel gradually shrank, and layers of strange red Pill Pattern began to appear on the surface, and there were faint electric arcs beating inside the elixir body.
At the ventilated rock hole above the stone chamber, the rich medicinal fragrance has already penetrated the restriction and turned into fiery red smoke rising up visible to the naked eye.
