There are nine levels in the practice of "Green Lotus Heart Sutra". Each level is a checkpoint and a bottleneck. If you are unlucky, it is not uncommon to be stuck for decades or even hundreds of years.

The first level of "Green Lotus Heart Sutra" requires finding a piece of extremely high-quality casting material, which must at least be of Saint grade. This is the minimum requirement. However, if you only use Saint grade as the foundation material for "Green Lotus Heart Sutra", then it will be difficult to practice to the ninth level, and breaking through to the King level is even more wishful thinking.

The foundation determines everything. The higher the quality of the materials, the higher the height that the "Blue Lotus Heart Sutra" can reach in the future after consumption.

The only two masters of the Qinglian Sect who were able to cultivate to the ninth level and break through to the emperor level, all used materials of the avenue level to build their foundations;

However, precious materials of the Avenue level are not so easy to obtain even in the upper realm. And even if you use Avenue level materials, you must perfectly match them with yourself to have a chance of breaking through to become an emperor-level powerhouse.

In the entire Qinglian Sect, there are at least eight hundred people who use Dao-level materials to build their foundations, but only two of them can eventually become emperor-level powerhouses.

"The Green Lotus Heart Sutra is extremely profound. This is the first great Dao-level technique I have come into contact with. It's a pity that I can't use the Yuan Yangzi bond to directly upgrade it to the maximum level!" Xu Feng felt regretful and shook his head.

Moreover, considering the grade of the Green Lotus Heart Sutra, the "Eternal Devouring Art" is only an immortal-level technique. Xu Feng is not sure whether it can devour the Dao-level Green Lotus Heart Sutra.

"The most important thing now is to find a Dao-level material that suits me. Otherwise, I won't be able to get started with the Green Lotus Heart Sutra!" Xu Feng couldn't help but sigh, and put aside the scripture in his hand that had become wordless.

At this moment, Xu Feng suddenly felt that his secret realm seemed to move. With a thought, the realm suddenly expanded, and Xu Feng's thoughts swept across the entire secret realm in an instant.

“Eh? This is…”

Xu Feng's attention was immediately attracted by the green lotus in the central lake of the secret realm.

This green lotus was originally formed from the half of the black lotus platform obtained by Xu Feng. It was originally a black lotus, but at some point, this black lotus slowly turned green from the root and became a green lotus.

"Green Lotus Heart Sutra, haha, this green lotus is a black lotus platform made of magic grade material, which evolved in my domain and naturally matches me. This is..." Xu Feng thought to himself, "But the black lotus platform was only a magic grade material. If I use it as the foundation material for my Green Lotus Heart Sutra, my future achievements will be at most the peak of the king level. It will be difficult to break through the emperor level, let alone reach the emperor level!"

In fact, it is difficult for most people to reach the peak of the King level by using immortal-level, god-level, and demon-level materials to build the foundation. After all, the quality of the materials cannot support the improvement of strength. But Xu Feng is confident that if he uses this green lotus, he should be able to reach the peak of the King level.

At this moment, the sky crystal ore that was originally stored in the secret realm suddenly flew up automatically and flew towards the green lotus in the lake. Pieces of sky crystal ores of different sizes all turned into dazzling divine light and merged into the green lotus.

After a short while, spots of golden light appeared on the surface of the green lotus, like bright golden stars.

"This is..." Xu Feng showed a look of surprise on his face. He didn't expect that this green lotus could absorb materials to improve itself. This surprised him.

"The Dragon Blood Shura Vine showed the ability to devour before, and now this Green Lotus also shows the ability to devour. Could it be that all this is related to my "Eternal Devouring Technique"? " Xu Feng thought to himself.

Xu Feng originally thought that it was just a change in his technique, but he didn't expect that the devouring effect would actually appear in every aspect of himself! Thousands of Void Sky Crystals were devoured, and then a crystal shining with colorful divine light also began to fly towards Qinglian;

"This, this is my Tianjing Divine Essence!" Xu Feng suddenly felt a pain in his heart and subconsciously wanted to stop it. However, before he could make any move, the flying speed of the Tianjing Divine Essence suddenly increased and instantly sank into the green lotus.

"Hiss!" Xu Feng sucked in a breath of cold air. This piece of Heavenly Crystal Essence was extremely precious. It was sold by gram on the market. Such a large piece of Heavenly Crystal Essence would be worth a lot of Chaos Coins. Xu Feng was really reluctant to let it be swallowed by the Green Lotus.

The next moment, the golden spots on the surface of the green lotus began to slowly extend and formed strange golden lines. It looked extremely mysterious and exuded a thrilling aura.

"Has this been promoted to the Great Dao level?" Xu Feng frowned slightly and felt it carefully: "No, it has not been promoted to the Great Dao level yet. What a pity for my Heavenly Crystal Essence!"

Qing Lian at this time was already infinitely close to the Great Dao grade, but unfortunately, it was still a little bit short. This little bit seemed insignificant, but it was like a chasm that could not be crossed at all.

The golden lines on the surface of the green lotus became more and more dense, and the light became more and more dazzling. Unfortunately, when the light reached its peak, the golden lines on the surface of the green lotus did not undergo any qualitative changes.

Just when Xu Feng shook his head and sighed, thinking that Qinglian had failed to advance, countless Chaos Coins suddenly flew up and flew towards Qinglian.

"Oh my god, that money was saved by me with great effort..." Xu Feng's face changed drastically when he saw this. He wanted to stop it, but after looking at Qinglian, he finally gave up.

There is no wrong version in the 1619 book forum!

"Damn it, Chaos Coins can be exchanged even in the upper realm!" Xu Feng couldn't help but sigh.

The currency of the upper realm is spirit crystal, which is one level higher than the best spirit stone. Moreover, in the upper realm, other currencies, as long as they are valuable, can be exchanged for spirit crystals at a certain exchange rate. The exchange rate between Chaos Coins and Spirit Crystals is relatively high. One spirit crystal is equivalent to 3.7 Chaos Coins. Now Xu Feng has thousands of Chaos Coins in his hands. Even in the upper realm, it is considered a considerable fortune.

When all the Chaos Coins were swallowed by the Green Lotus, the Green Lotus suddenly burst into a dazzling divine light, and even Xu Feng's consciousness was pierced and couldn't open his eyes. When the light dissipated, Xu Feng looked at the Green Lotus again and found that the Green Lotus at this time had completely changed.

Although it still looks like the green lotus, the golden lines on the surface have completely disappeared, replaced by tiny golden runes that are faintly visible in the green lotus. At the same time, the color of the green lotus has become more transparent, and it looks like it was carved from a whole piece of jade, like a perfect work of art.

"Haha, Dao level. I didn't expect that you could actually be promoted to Dao level!" Xu Feng finally showed a smile on his face.
