Half a month passed, and Old Man Murong rushed out of the alchemy room with an extremely excited expression, handed over the nearly three thousand Phantom Yuan Pills refined this time to Ye Boyun, and said, "Boyun, these pills Tianchen hopes that you will share them equally with Fan Niang and Liang Zheng, and unify to improve the strength of our side." However, it must be remembered that this elixir only takes effect once for a martial artist, so it must be distributed carefully. Also, although the elixir this time has been improved, it can only be taken by those who have reached the strength of a martial artist. ”

"Yes. Ye Boyun still has a lot of respect for Old Man Murong, and after respectfully taking the elixir, he distributed it with Fan Niang and Liang Zheng on the spot.

Seeing this, Murong Hai nodded with satisfaction and said, "Tianchen has thought of a new pill in the past two days, I will go in and develop it with him, this time it may take a long time, before we come out, we must not come in and disturb, you know?"

"Yes. ”

Ye Boyun nodded heavily again, and then watched the old man enter the alchemy room.

The three daughters of Mu Ningxue, who were not far away, stopped Old Man Murong's words clearly, and after glancing at each other helplessly, they sighed at the same time.

"Old man, come and see how this recipe of mine is. ”

Seeing Murong Hai walk into the alchemy room again, Ye Tianchen hurriedly beckoned the old man over.

Murong Hai took the formula, nodded while looking at it, and said, "Tianchen, your formula is really good, but if you want to condense the Yuan Force Vortex in the martial artist's body, this is really a bit risky." ”

"I know. Ye Tianchen's expression was extremely serious, in fact, this formula could not be said to be something he came up with, but according to the formula of the Zhuji Dan of the cultivation world, after improvement, combined with the cultivation methods of the martial artists in this world, he came up with a formula. Tsukidan is not difficult to practice, the difficulty is that after the martial artists of this world inhale the energy into their bodies, they directly transform it into their own energy. From a certain level, this practice is actually to divide one's own energy into two with the energy of heaven and earth, essentially disconnecting from each other.

Therefore, if you want to gather an energy vortex in the body of a warrior, you must form a prototype in the body of the warrior through the energy of the elixir, and then support the operation of the vortex by the Yuan Force of the warrior itself, so that you can pass through the operation of the vortex, absorb the energy of heaven and earth into the body, and absorb the energy of heaven and earth anytime and anywhere, and then transform it into your own energy through the vortex, which is equivalent to every martial artist who takes this elixir can maintain a state of cultivation anytime and anywhere, greatly improving the speed of cultivation of the martial artist. It is similar to the Holy Spirit Bead in Ye Tianchen's body.

After Ye Tianchen was silent for a while, he said slowly: "At present, there is less and less time left for us, simply relying on elixir to improve our strength, although we can create batches of masters in a short period of time, but after all, it can't compare to a great force like Stormwind City that has been inherited for thousands of years." Moreover, the strength gained by taking pills is actually equivalent to squeezing out the potential of martial artists in advance to a certain extent, so that it will be even more difficult for them to improve their strength in the future. Therefore, we can only fundamentally improve the strength of each martial artist, which is the real long-term method. ”

"Yes, you're right. "Murong Hai is already proficient in the way of pills, so he naturally knows the truth. It's just that the idea proposed by Ye Tianchen is really too appalling, and the amount of yuan power in each martial artist's body is different, even if it is a martial artist of the same level, the amount of yuan power stored in his body is more or less. This way of relying on one's own yuan force to support the formation of the vortex is too risky, he sighed, shook his head and said: "The old man naturally understands, but if the martial artist after taking the pill cannot support the formation of the vortex, then he will be squeezed dry by the vortex and die!"

"Since ancient times, it has been an eternal law that if you want to get, you have to give. Ye Tianchen nodded, a fierce glint flashed in his eyes, and said, "Even if you don't use this elixir, aren't the martial artists always facing all kinds of dangers in the process of cultivation? The difference is that this time the danger comes from within them. ”

Murong Hai couldn't help but be a little stunned, seeing Ye Tianchen's expression, he knew that he couldn't persuade him, so he could only sigh in the end and said, "Okay, since you are so determined, then let's give it a try, but we must try to reduce the energy required to form a vortex as much as possible." ”

"Hehe, don't worry, boy, I already have a plan. ”

Ye Tianchen chuckled, as long as the old man agreed, he had also taken Zhuji Dan in his previous life, so he naturally had a certain understanding of this pill. In the previous life, the requirements for taking Tsukidan were not high, and the threshold for transforming into this kind of pill that can form a whirlpool will not be high. Said slowly: "If we want to reduce the energy required when the vortex is formed, as long as the energy of the elixir energy is sufficient, and to control the energy balance in the elixir, we can add some Heavenly Star Grass immediately like the last time we refined the Phantom Yuan Pill." What do you say, old man?"

"Well, that's a good idea. Murong Hai nodded, looked at the formula carefully, and then asked suspiciously: "Most of the elixirs in this formula are attributes that help refine and absorb energy, but there are not many elixirs that have a certain amount of energy in themselves!

"Hehe, I'm going to fill it with my own energy. Ye Tianchen smiled and touched his nose and said.

"What!?"

Murong Hai glared at him in horror and shouted angrily: "Are you crazy? Looking at the dosage in your formula, coupled with your magical refining technique, there are at least five or six hundred pills coming out of this furnace, so many pills are filled with your own energy, can you withstand it?"

Ye Tianchen had never told anyone about the existence of the Holy Spirit Bead in his mind, and naturally no one would know about the function of the Holy Spirit Bead to absorb energy on its own. Seeing that Old Man Murong really cared about himself from the bottom of his heart, his heart warmed, and he slowly handed his hand to the old man and said, "Old man, pass your mind into my body, and you will be able to know." ”

Murong Hai's body shook slightly, sinking his mind into the body of others, and both sides had to take huge risks. No matter which party has ulterior motives, it is not impossible that the other party can be seriously injured or even killed directly. Seeing Ye Tianchen's sincere gaze, the old man was moved by Ye Tianchen's trust in him, nodded slowly, and said, "Okay, you have to be careful yourself." ”

"Don't worry!"

Ye Tianchen chuckled, and after finding that the old man's mind entered his body, he said softly: "Don't resist, old man, the kid will take you to see something." ”

Murong Hai was puzzled in his heart, but out of trust in Ye Tianchen, he still relaxed his mind according to his words, and let Ye Tianchen bring his mind into his mind, and immediately sensed the huge energy in Ye Tianchen's sea of consciousness, as well as the strange black and white bead at the source of the energy, and felt the huge power faintly emanating from it, and suddenly his body trembled.

Ye Tianchen saw that his goal had been achieved, so he took Murong Hai's mind out of his mind, slowly opened his eyes, and said with a smile: "Old man can rest assured now, right!?"

"Hey, you kid...... Thinking that Ye Tianchen still had such a terrifying treasure hidden on his body, no wonder this kid could grow so fast, no wonder he could come up with refining this terrifying elixir.

"Hey, hey. Ye Tianchen sneered and said softly: "Old man, this is my biggest secret, boy, you can ......

"Hey, do you think the old man has lived in vain in this life?" Old man Murong glared, shouted angrily, and then sighed: "I know that your kid is a person with great opportunities, since you have such a treasure, then you must make good use of it." ”

"Hmm. Ye Tianchen smiled bitterly in his heart, he wanted to make good use of it, but the key was that the Holy Spirit Bead was willing to let him use it.

"Okay, since your kid has such a treasure to protect himself, then the old man has nothing to worry about. Murong Hai nodded and said, "Let's start!"

After the tedious research of the medicine and sorting out the required elixir, the development of a new elixir this time finally began.

During this period of experience in refining medicine, Ye Tianchen's control of his own energy and his experience in refining medicine have made great progress. The refining work began with a light car.

Time passed little by little, and the elixirs, with the tacit cooperation of Murong Hai and Ye Tianchen, gradually turned into a ball of crystal spiritual liquid.

Murong Hai watched Ye Tianchen slowly purify all the elixirs after being refined, and felt a lot of emotion in his heart. In just one month, two kinds of pills have been developed, which can definitely benefit all the martial artists in the entire continent. Compared to the peerless elixir he thought he had developed before, he didn't know how many times stronger.

Fortunately, Ye Tianchen developed the pill purely for the purpose of self-preservation. If Ye Tianchen was trying to dominate the mainland, it would definitely set off a rare turmoil.

However, Murong Hai's worries will be staged step by step in the near future. Although Ye Tianchen was forced step by step onto the road of dominating the continent, he did stage a huge turmoil, and this turmoil eventually became more and more intense......

"Condensation!"

The last one against Ye Tianchen
