The requirements of the first level are very simple. After releasing a sword energy with a specific method, it will not dissipate for five breaths, and can perform the simplest linear attack. This is naturally not difficult for Li Fei, but Li Fei increased the difficulty by himself, not only greatly strengthening the power of the sword energy, but also increasing the time for maintaining the sword energy to an incense stick of time, and also controlling the sword energy to attack from various angles.

Three days later, Li Fei had fully achieved the goal he set and began the second level of cultivation. The second level was just an extra sword energy, and so on. Due to the previous practice of Tianchen Shield, Li Fei was doing it smoothly on the basis of increasing the requirements.

Three months later, Li Fei successfully reached the fifth level of the "No Nameless Sword Score" and could control the five sword energy to attack. Considering the power of the sword energy, Li Fei reduced the time requirement for maintaining it and kept it for half an incense stick of time. This ensures that each attack can reach about half of the attack power of the silver sword, but the combined power can reach more than twice!

Starting from the sixth level, there is a qualitative change in requirements. It is no longer a simple attack requirement, but an accurate "fusion". Simply put, it is only necessary to control two powerful sword energy, but it is quickly fused before attacking the enemy, so as to release greater attack power. It is easy to say, but it is quite difficult to operate. Not only do you need to seize the opportunity, but you also need to accurately control the distance and speed of the two sword energy. As long as there is a slight mistake, all your previous efforts will be wasted.

After another half a year, Li Fei fully mastered the sixth level and tried his best on a rock. The effect was quite good. He could easily cut a large stone into several pieces, basically reaching about 15 times the attack power of the silver sword. Li Fei was not satisfied, because with this power, there was no advantage, and it was just slightly stronger than the same level, and it was not very meaningful.

Time flies, and in a blink of an eye, Li Fei and Yue'er stayed in this underground stone cave for almost five years, and only communicated with Yue'er a few times. Li Fei finally cultivated the "No Nameless Sword Score" to the eighth level, and could control five powerful sword energy to fusion attacks at the same time, but its power was more than three times the attack power of the silver sword! Li Fei was confident that with this strength, he should be able to fight against those "black robe men" of the counterfeit elixir masters. Of course, it is far from enough to defeat the opponent by this point alone. Li Fei finally gave this sword energy fusion attack a domineering name: Life-seeking Sword Thunder.

In addition to practicing the "No Nameless Sword Note", Li Fei naturally would not relax his own cultivation. He had used up all the top-grade spiritual transformation pills, and there were still many medium-grade spiritual transformation pills. After five years of hard work, Li Fei's cultivation has improved a lot.

According to Li Fei's original plan, he originally wanted to practice the ninth level of "Sword Thunder for Life", but unfortunately, after half a year of hard work, there was no hope at all. The main reason was that the divine consciousness was not enough to control the seven stronger sword energy. If the power of the sword energy was reduced, it could be barely achieved, but the power was even worse, so in the end, I could only give up temporarily.

Finally, it is worth mentioning that due to the practice of "Sword and Thunder for Life", Li Fei's use of the Tianchen Shield has also been slightly improved.

According to the old habit, after Li Fei finished his practice, he took a bath in the underground river. During the bathing process, he found that the water quality in the underground river was quite good and collected some. Finally, Li Fei went to see Yue'er and found that she was still practicing. She had a full meal and fell asleep after falling asleep.

Two days later, Li Fei woke up and felt in good condition. Looking at the gravels that were broken by him on the ground, he had the urge to try again "Sword Thunder for Life". Looking at the last largest huge rock leaning against the stone wall, the "Sword Thunder for Life" was quickly activated, and five bright sword energy rushed towards the middle of the huge rock at a lightning speed. At the moment of colliding with the huge rock, the five swords merged into one and burst out dazzling light. After a loud bang, the huge rock that exceeded several feet was cut in half!

Li Fei looked at Zhanguo and was very satisfied. He was about to leave and went to find Yue'er when he suddenly found that the huge rock was hollow. Li Fei looked at Yue'er and saw that she had not come out anyway. Out of boredom, he walked over and took a look, and soon showed a surprise expression!

When he came to the stone cave where Yue'er was practicing, Li Fei found that Yue'er was angrily pounding at the stone wall, with no rules at all, and advised him: "Yue'er, don't worry, you haven't practiced well for a while, just practice slowly."

Yue'er stopped attacking and said angrily: "This damn eighth level, I have been practicing for two years, but I still can't fully grasp it. I get angry when I see it."

Li Fei hugged Yue'er in his arms and comforted him: "Don't be sad. Didn't we discuss it last time? The main reason is that your spiritual consciousness is not strong enough, and your current practice is not in vain. I guess you will be able to perform it when you enter the late stage of Foundation Establishment. "

Yue'er's anger faded a little and said helplessly: "I also know the reason. I just want to practice the eighth level as soon as possible. It may not work if I have entered the late stage of foundation building for decades. By the way, Brother Fei, have you practiced the eighth level?"

Li Fei knew that Yue'er was angry about the eighth level of things and replied vaguely: "It's similar to you, sometimes it's successful, sometimes it doesn't work, it depends on luck."

Yue'er suddenly gave Li Fei a pink fist and cursed: "I want to lie to me again! I know that your divine ideology is much stronger than mine, so I must have succeeded, hum..."

Li Fei quickly surrendered and said seriously: "Since Yue'er believes that I succeed, I must succeed! Haha..."

After a while of the drama, Li Fei said to Yue'er mysteriously: "There is good news. A close-range teleportation array is hidden in the pile of rocks opposite. Should we explore it?"

Yue'er said without hesitation: "Of course I'm going! If there is any danger, I just happened to try the power of the eighth level of the "No Nameless Sword Score" that I haven't fully practiced just now."

Li Fei echoed: "It's a must! If Yue'er's attack fails accidentally, I will make up for it immediately! By the way, Yue'er, I gave this unique skill a name, "Sword Thunder for Life". What do you think? In this way, we are famous."

Yue'er's eyes lit up and she agreed: "Okay! It's called 'Sword Thunder for Life'!"

Li Fei and Yue'er soon arrived in front of the teleportation array, cleaned up the dust, revealing the original appearance of the formation. This was a small teleportation array with a diameter of about half a meter and precisely positioned. Fortunately, it was not a key part. Li Fei and Yue'er copied it and took half an hour to repair it according to the original traces.

After repairing, Yue'er suddenly remembered something and said, "Brother Fei, this is a precisely positioned teleportation array. It requires nine ordinary spirit stones and one top-grade spirit stone. Since it was useless for me to have top-grade spirit stones before, there was no top-grade spirit stone..."

Li Fei didn't say anything, and took out nine ordinary spirit stones and put them in the formation trough, then took out a top-grade spirit stone and put them on it. He said seriously: "Yue'er, we are about to be teleported to an unknown place, so you must not be underestimated. I am responsible for activating the formation and resisting space pressure. You are responsible for vigilance to prevent accidents."

Yue'er nodded, took out a pair of green mother-child rings, held them in her hands, and stood back to back at the center of the formation with Li Fei.

Li Fei pinched the magic tricks and activated the formation, then quickly released the Tianchen Shield, wrapping the two of them tightly. A white light flashed and lost its trace. After Li Fei and Yue'er teleported away, the cave returned to peace. After a while, a light sound came from the cave, and the formation exploded on its own, becoming an irreparable fragment...

Not long after, Li Fei and Yue'er appeared in the fiery red. Li Fei instantly felt an unbearable heat wave around him, and he was still in the sky dust shield. Yue'er naturally felt it, quickly released the mother-child ring. The small ring tied the two together and flew to one side. The big ring formed a thick green protective light curtain, which felt a little better.

Only then did Li Fei have time to look at the surrounding environment, but after just a glance, he shouted that he was unlucky and had a strong premonition of being plotted against!

This space is not small, with a radius of seventy or eighty feet in a circle, and is a confined space. Below is rolling magma, surrounded by rock walls that are roasted red, and there is almost no place to settle down. If it weren't for the fact that this space was not large enough, Li Fei even suspected that he had been teleported to the center of the earth!

At this time, Yue'er's face was lost, but she was soon roasted and her face turned red, and she anxiously looked for a place to stay.

Li Fei forced himself to calm down and began to find a suitable place to settle down. Suddenly, Li Fei found a place in the middle of the stone wall opposite. There was a possible depression due to the collapse of the rock, which was several meters wide enough for the two to settle down temporarily. He hurriedly said to Yue'er: "Fly fly to the opposite side, there is a place where you can temporarily hide."

Yue'er had no idea at this time. After hearing Li Fei's words, he rushed over. After rushing through the center of the magma, Yue'er was impatient and lowered the height. A sudden upward magma hit the green protective light curtain, and the light curtain dimmed instantly. Yue'er was so scared that she exclaimed. Fortunately, with this momentum, Li Fei and Yue'er finally fell into the depression before the green protective light curtain completely collapsed!

When Li Fei approached the depression, his hands were swaying wildly, and he sprinkled a large amount of heat-resistant and heat-insulating debris into the depression, forming a loose accumulation. The bottom layer was bricks and ceramic tiles, and there were about a dozen bags of cement in the middle, two large water tanks on the cement, and thick solid wood boards on the water tank.

Just as they had hurry to prepare these temporary insulation measures, Li Fei and Yue'er landed on the top solid wood board, and the two of them breathed a sigh of relief. At this time, Li Fei was extremely glad that he did not throw away these seemingly useless things. Another very important reason is that the blue wrist guards are big enough.

After being down-to-earth, Li Fei took out a water tank and filled all the cement bags piled up in advance to prevent them from dissipating immediately after burning. In addition, considering that although this space is relatively large, the air is extremely poor, Li Fei took out a small oxygen cylinder to release most of the oxygen, and retain a small amount of oxygen for emergencies. Anyway, cultivators in the foundation-building stage don’t need much, so some of them can last for a long time.
