As for Sun Bing at this moment, he also did not stay where he was. He entered the universe inside his body again with a thought.
After all, for the safety of the Sea of All Realms, he had left the Nuwa Stone, the Chaos Bell and even the Chaos Pearl here.
Now he only has Chaos Green Lotus and Kunlun Mirror in his hands.
They seem to be two chaos-level treasures, but the Kunlun Mirror is good at assassination. Once there are many enemies, its greatest use is to save one's own life.
But it can be foreseen that the number of enemies will definitely not be small. Once he goes back in time, the Jiuli clan will be surrounded and suppressed by the enemies.
Moreover, without the restraint of an opponent, the enemy can also go back in time to intercept his attack.
All in all, for Sun Bing, the effect of the Kunlun Mirror is really useless.
The main reason why this treasure is not left in the Sea of All Realms is to guard against Kunlun Heaven.
Even though Sun Bing has refined the Kunlun Mirror, he is still very afraid of Kunlun Heaven, which gave birth to this treasure.
But as a result, the power he carries with him at all times has weakened a lot. Considering the battle he may encounter next, he must improve his strength as soon as possible.
Sun Bing gave up on improving his cultivation. Even though he was extremely talented, he never found a chance to make a breakthrough.
The only way is to get a magic weapon.
Following a dull sound, the sword box behind Sun Bing opened directly, and thousands of flying swords soared into the sky.
The most eye-catching thing is the four divine swords that shine with a cold light. Even if they are far apart, they are still like lights on their backs.
Looking at the scene in front of him, Sun Bing felt filled with emotions.
The Four Swords of Zhuxian have been with him for endless years, and they have always been regarded as life-saving trump cards.
It's a pity that as his cultivation level increases, the enemies he encounters become more and more powerful, so that the Four Swords of Zhu Xian are gradually unable to keep up with him.
Many thoughts flashed through his mind, and then he could be heard sighing:
"Old man, I will not give up on you, and I will let you transform next."
At this moment, the Four Swordsmen of Zhu Xian seemed to have heard this burst of instructions and made a very loud sword sound.
At this moment, Sun Bing no longer hesitated. With a thought in his mind, all the sources of Heavenly Dao that he had killed during this period, except for the Source of Weitian that had been used and sacrificed, were all here.
Such a huge gathering of the origins of heaven, not to mention the Four Swords of Killing Immortals in the void, even the universe within the body gave birth to a greed.
After all, for the inner universe, these origins are also unimaginable treasures.
Fortunately, Sun Bing, as the master of the entire inner universe, possesses supreme majesty. With a thought, he forcibly stopped the greed of the inner universe.
Then, he waved his big hand, and the majestic source of heaven immediately flew towards the Four Swords of Killing Immortals.
Feeling the extremely rich Taoist charm and rules around them, the Four Swords of Zhu Xian seemed very excited, like hungry fish, crazily devouring all the power around them.
For a time, the Four Swords of Zhu Xian, which were already filled with cold light, were now surrounded by many Dao rhymes intertwined and various rules criss-crossing them, making them look very spectacular.
The most important thing is that as the source of Heavenly Dao devoured increases, the momentum displayed by the Four Swords of Zhu Xian becomes more and more powerful.
Among them, the one that Sun Bing pays the most attention to is the Immortal Sword.
After all, among the four swords, only the Immortal Sword is still at the level of an imperial weapon.
It is precisely because of this that the power of the once invincible Zhuxian Sword Formation has been greatly reduced. On several occasions, the enemy has even escaped from the position of the Zhuxian Sword.
Now, under the infusion of the infinite source of heaven, one can only feel a sharp edge suddenly erupting.
The Immortal Sword, which was just an imperial weapon before, immediately transformed into an innate spiritual treasure.
"Boom"
All that could be heard was a dull sound, thick clouds gathered in the sky, and a catastrophe followed.
In this regard, Sun Bing showed no fear on his face, and he did not even deliberately activate the Immortal Sword.
But this divine sword turned into a stream of light and flew straight towards the nine heavens.
Earth-shaking roars continued to sound, and the sky was filled with endless thunder dragons.
Although he had witnessed it several times with his own eyes, Sun Bing still marveled at the power of the Heavenly Tribulation when looking at the scene in front of him.
Fortunately, it was him. If he were an ordinary person, facing such a terrible thunder disaster, he could only end up with hatred.
In just a short moment, the thunder calamity that was so powerful just now had completely disappeared.
As for the Absolute Immortal Sword at this moment, it was shining with a cold light and flew towards the origin of heaven again.
Even after helping the Juexian Sword transform into an innate spiritual treasure, there is still a lot of the original source of heaven left.
After all, during this period of time, there were not a few Tiandao who fell under Sun Bingjian, and they were all very top Tiandao.
It is no exaggeration to say that every source of heaven can cultivate an innate treasure.
But now, all the origins of Heavenly Dao have been turned into food for the Four Swords of Zhu Xian.
I saw that the four swords were wrapped in endless Taoist rules, but their own sharp edges became sharper.
If the original four-handed swords could only be regarded as the most common innate spiritual treasures, then the current level has obviously improved a bit.
This is just the beginning.
For his four swords, Sun Bing was not stingy at all. Not only the huge source of heaven, but also the power of the entire universe was constantly refining these four swords.
In addition, Sun Bing waved his big hand in front of him, and various precious magical metals and irons appeared one after another.
Most of these were obtained from Penglai Immortal Island, and a small number were accumulated by Sun Bing over a long period of time.
As soon as these magical metals and irons appeared in the void, heavenly fire would emerge from the vast universe and melt these magical metals and irons.
The remaining molten iron gradually flew towards the Four Swords of Zhu Xian under the control of Sun Bing.
Afterwards, many Tao rhymes surged and all kinds of rules criss-crossed, and the molten iron gradually merged with the four divine swords.
After absorbing these magical metals and iron, the four swords glowed with dazzling light, and their edges became sharper.
Seeing this situation, Sun Bing's heart was filled with joy.
It can be seen from the current fluctuations that he will soon be able to obtain the more powerful Four Swords of Zhu Xian.
Just when he was extremely excited, he suddenly discovered that the mark he had left had been activated.
In the end, he could only glance at the Four Swords of Zhu Xian, which was still in the process of transformation, and with a thought, he left the universe inside his body.
Just when he returned to Fei Lian's cave, he could see the other party right in front of him.
After seeing Sun Bing's figure, Fei Lian nodded calmly:
