The spiral staircase leading to the basement of the castle is very long, and the stone slabs that have fallen into disrepair are covered with moss, and if you don't step on it well, it will slide down, if it is not for Lu Gang's cultivation, it is really very dangerous.

"The gravity here is getting bigger and bigger the further it goes, it has exceeded 20 times the gravity, and under such a large gravity, it can still emit such a hot energy impact! What's going on?" The more Lu Gang went down, the more thrilling he became.

"If you can withstand 38 times the gravity, you can see me, if you can't do it, go back to cultivation, when you can do it, come again!" A tyrannical voice rang out, followed by the sound of chains.

The words reached Lu Gang's ears, and the burning feeling became even stronger.

"It's already 30 times the gravity, and the pressure is really not small, it seems that I have to use my true yuan force to balance this powerful gravity, and this strong burning feeling makes it even more difficult for me to walk. It's just the right time to test my cultivation!" Lu Gang's unwillingness to admit defeat was aroused.

31 times, 35 times! Lu Gang had to stop for a while, and the True Yuan Power spread all over his body, allowing himself to adapt to this powerful pressure.

Today, no matter what, I want to see this fierce man underground, Lu Gang gritted his teeth and insisted on going.

Smack~ Lu Gang finally walked to the bottom, the 38 times gravity was too huge, so that Lu Gang's body on the 4th floor of the refining body couldn't help but tremble.

Looking up, Lu Gang was stunned by the scene in front of him.

Several thick chains were locked on the body of an old man, who was naked, and countless wounds showed the old man's bravery.

Powerful fluctuations were emanating from his body, making a cyan dragon tattooed on his body seem to come back to life.

With unkempt white hair and no wind automatically, the old man seemed to be in great pain and was trying to suppress something.

The body that had been burned red by the scorching energy was constantly emitting a stream of energy full of heat energy, and the thick chains on the old man's body were more like they had been smelted by a blast furnace and showed a dark red.

"More than 20 meters away from me, hold on for 20 minutes, and if you can't do it, you will die!" The old man's reddened eyes suddenly opened, these were a pair of angry and crazy eyes.

As the old man spoke, a powerful momentum rushed towards Lu Gang.

Lu Gang, who was already having some difficulties under 38 times gravity, had to sit cross-legged and strive to encourage his cosmic qi to run all over his body, so that he would not be injured by this tyrannical energy.

"Damn! You all deserve to die! Kill! I'm going to kill!" The chain made a loud noise, and the old man seemed to be unable to control the energy in his body, and roared loudly.

Lu Gang couldn't leave if he wanted to, the huge scorching energy swept in, and he could only continue to increase the cosmic qi, but when the old man emitted a huge coercive impact energy, Lu Gang's cosmic qi couldn't hold it, and it was about to be shattered.

When the cosmic qi and the true yuan force combined, the two forces were fused together by the powerful pressure, forming a light shield like an energy shield three inches outside Lu Gang's body.

Gravity, violent cosmic qi and scorching heat are three powerful forces surging throughout the basement, like a tide, wave after wave, wave after wave impacting the landing gang.

Poor Lu Gang felt like a small boat, floating on the stormy sea, threatening to capsize at any moment.

"The fourth layer of my refining body can't block the impact of this level at all, it's not good! If this continues, the shield formed by my True Yuan Force and Cosmic Qi will be broken sooner or later, and once the shield is broken, it will be the time when I die!" Lu Gang couldn't help but get anxious.

When the shield is broken, another shield is condensed, but the three forces outside are getting bigger and bigger, and the frequency of impact is getting higher and higher, and soon the condensation speed of the shield cannot keep up with the speed of the shield breakage.

There were several more turbulent energy impacts, Lu Gang's shield was already damaged, and seeing a powerful force rushing towards him, Lu Gang knew that his shield was going to be finished, click~ The energy shield was shattered, and a burst of unparalleled violent power rushed towards Lu Gang......

"Damn it! I'm not going to die like that!" Before the condensation shield could be completed, Lu Gang felt the arrival of the crisis.

Lu Gang's mind quickly flashed through the knight inheritance mastery he had learned.

"Unyielding!" Boom~ The inside of the body exudes a pure spiritual power, which is completely different from Lu Gang's cosmic qi and true yuan power, and it is a spiritual power that cannot be seen or touched.

When this pure spiritual power was entangled with the cosmic qi and the true yuan force, the three forces had an incredible chemical reaction.

Smack!~ After a soft sound, Lu Gang opened his eyes, all the turbulent waves disappeared, Lu Gang was shrouded in a glass cover with a diameter of about 3 meters, and the energy and gravity emitted by the old man could only rage outside the glass cover.

"Huh! What is this, I can't even feel gravity, haha! This energy mask is powerful! In this hood, I feel like I can exert 200% of my power! What the hell is this?" Lu Gang was pleasantly surprised.

"Ahh Elementary field!? You've actually practiced the realm?! Hahaha! Good, good. Haha, yes!" The old man under the chain was already a little crazy, and when he saw Lu Gang holding up the five-meter aperture, he roared even more crazily and laughed wildly.

"Boy, try to absorb the energy emitted by the old man, as much as you can absorb! Cheap you, ah! Ahh Kill you!" The old man seemed to be sober for a while, confused for a while, and spoke upside down.

"That's right, with so much excess energy in the sea, this is definitely an excellent place for cultivation!" Lu Gang, who was overjoyed when he heard the words, ran the Great Zhou Tian with all his might.

The surrounding heat energy and cosmic qi sea water like the sea were surging frantically towards Lu Gang, and these energies were different from the wild energy absorbed in the gravity chamber, which were all very high-quality cosmic qi that the old man had transformed.

The huge power was absorbed into Lu Gang's body, and the scorching energy was all absorbed by the True Yuan Force, and the incomparably cool cosmic qi rushed into the cosmic sea in Lu Gang's brain like water.

There is also a line of spiritual power that has also continuously rushed to the edge of the cosmic sea, subtly expanding the width of this land cosmic sea.

The old man in the frenzy, as those scorching and violent qi were absorbed by Lu Gang, his consciousness gradually came to his senses, and the old man who opened his eyes again was no longer tyrannical and crazy.

"Hahaha, there is no end to the sky, good boy, I want to thank you for fulfilling me! Suck it, suck it all you want! Hahahaha!" The old man laughed, the laughter at this time was completely different from just now, this time it was the excited laughter for the rest of his life.

"It's too powerful, these powers are too powerful and pure, even the scorching energy can nourish my cultivation force, and the energy filtered through the realm can also nourish the acupoints around me, so that I can absorb it boldly with confidence, it's so comfortable!"

"The Xiuzhen Force has perfectly condensed into a crystal state, this is really a perfect crystal! Keep pouring energy and see if there's any change!" While absorbing it, Lu Gang looked inwardly and paid attention to his dantian and spirit, and was very surprised to see this scene.

"The spiritual sea is actually expanding, the cosmic qi lake in the spiritual sea is almost nine thousand kilometers, this is no longer Hubo, this is simply the ocean of cosmic qi, and the cosmic qi sea is constantly increasing within the spiritual sea. It's incredible!" As Lu Gang continued to absorb, surprises followed.

Lu Gang fell into the pleasure of increasing strength, especially the astonishing speed of energy absorption in the spiritual sea, the huge lake formed by cosmic qi for nine thousand kilometers churned huge water waves, and the higher the water waves, the larger the area of the lake.

The cosmic sea of qi was turbulent, and there seemed to be a domineering white light passing above the sea of qi, and the white light was scattered everywhere and the waves were separated from the left and right, just like the ministers visiting the king.

"Huh? How could this white light be so similar to the fist print on the knight's stone tablet? Is this part of the legacy?" Lu Gang thought curiously, patiently and carefully observed the fluctuations between the flickerings, and slowly comprehended this style of boxing through careful observation.

I don't know how long it took, Lu Gang felt that the energy around him was getting less and less, and he couldn't help but stop absorbing it and opened his eyes.

Huge metal chains were scattered on the ground, and the old man under the chains was no longer there.

The gravity in the basement also returned to its due level, and Lu Gang stood up in wonder.

"Come and see me on the second floor!" An old voice came, and it should have been the old man in the chain just now.

Lu Gang, who felt that he was full of strength, waved his right hand and casually punched out, and heard the sound of air boom~ explosion.

"With a casual blow of his hand, he is no longer under the inch of strength that he used to use the full strength of the True Yuan Force to excite with all his might! The strength has increased by at least three times." Lu Gang shouted in surprise.

Following the scorching aura, Lu Gang came to a large room on the second floor of the knight's castle after a while.

The room was very simple, a huge practice platform with swords and shields around it. An old man wearing a cyan armor and a poker face sat on the practice platform, the old man was expressionless, and the only smart eyes on his face seemed to be able to see through people's hearts and lungs, and he was looking at himself at this time.

Lu Gang hurriedly took two steps forward, arched his hands and said, "Knight Academy student Lu Gang, thank you for the grace of your predecessors."

"Hey, pass on the gong? Forget it, but boy, the old man wants to tell you that the energy you absorbed saved the old man's life, you can say what you want!" The old man in Tsing Yi spoke in a simple and clear way, a typical military-style conversation.

Lu Gang touched his head and said, "I inadvertently saved my seniors, and the cosmic qi of my predecessors has also been absorbed by me a lot, so let's even do it!"

The old man in Tsing Yi looked at Lu Gang for a while, and probably felt that Lu Gang was not humble, so he said: "Okay, if you say it's flat, it's flat, Lu Gang, right!" Yes, from today onwards, you will come to the castle once a day, and I will guide you in your practice! You go back first!"

Lu Gang was overjoyed when he heard this: "Thank you senior!"

Lu Gang, who walked out of the knight's castle, suddenly felt a wave of hunger hit him, and the hunger was so high that he could swallow a cow.

Inside the Imperial Study.

"Your Majesty the Emperor, student Lu Gang has been in the knight's castle for a day and a night, and he hasn't come out yet! The other two academies came back the same day, and then they each started their retreat! In addition, the scorching energy emitted from the castle has disappeared inexplicably!" The vague figure beside the bookshelf said.
