Chapter 1620: Three difficult problems (on)

Guo Yi had just returned from attending a meeting in the DPRK, and is now dealing with official duties in the study.
Recently, Chen Fan learned that Guo Yi was already more than 700 years old. This is probably the second oldest person Chen Fan has seen.
The first one is naturally the one who listened to the Lanzong inner world master to ask the sky, and realized the namelessness of the heaven and earth avenue.
But in fact, whether he can be counted among them is still worth considering.
After all, to Wuming, he no longer has the concept of time, he is immortal, immortal, immortal.
In terms of the age of ordinary monks, Guo Yi is definitely the biggest.
At such an advanced age, he still handles official duties in person every day, which is enough to see how hard Guo Yi has been.
At the same time, because of the Chen Dynasty system, Guo Yi, the prime minister, has no real power except for his high prestige. His rights are firmly controlled by Shang Shutai, and Guo Yi can only handle small things.
From this we can also see how difficult it is for this little old man who is always smiling.
Chen Fan came outside Guo Yi's study and bowed with a fist, "Grandpa Guo, Chen Fan has something to see."
After hearing the words, Guo Yi immediately put down the jade pen in his hand and said, "What are you doing so politely in your own house? Just come in."
Chen Fan opened the door and walked into the study to ask if he had time, and then slowly opened his mouth: "This is Grandpa Guo. I have almost recovered from my injuries recently. Can I practice my arm?"
Upon hearing this, Guo Yi sighed.
"Fan'er, it's not that I dragged you on purpose, but something went wrong about the sacrifice of the arm."
It turned out that half a year ago, when Guo Yi agreed to Chen Fan, he hadn't thought about the weapon arm refined by the One-armed Venerable, even if it could not reach the level of the ultimate magic weapon, how could it be casually sacrificed?
After many times of my own research and after consulting with a few trusted friends, everyone agreed that we should re-train this arm and make it come alive again.
Tiancai Dibao is essential.
First of all, it is necessary to purify the sand with the spirit of the soul, which is transformed by a ray of soul left in the world after the death of the monk in the realm of the emperor.
The whole body is crystal clear, like sand.
Generally speaking, the magic weapon for refining the spirit of the spirit, the soul cleaning sand is an indispensable thing, because it is the cleaning sand made by the monk soul, which can inject a touch of life into the dead.
And after having the spirit to clean the sand, a little ancient god's blood is needed.
This is even more difficult to find. After all, the ancient gods are a race that only exists in the long river of history. Legend has it that they were extinct in the Kyushu mainland before the ancient times.
Now only a few words in the fragments can know the power of the ancient gods.
Legend has it that the ancient is tens of thousands of feet tall, and the power of the flesh can open the sky!
Moreover, their corpses are immortal after death, and there are often body refiners who seek out the corpses of the ancient gods and bathe them in the blood of the ancient gods, which can cost decades of hard work.
Only in the Middle Ages, the last corpse of an ancient in historical records was also exhausted.
It's just that one or two bottles of ancient god's blood have been collected by some family or force once in a while, and every birth will cause earth-shattering waves.
The reason why the sacrificial arm needs the blood of the ancient gods is to use the blood of the ancient gods to thoroughly integrate Chen Fan's shoulders with the arms after the sacrificial practice, and never distinguish between each other.
If there were other heavenly materials and earth treasures to replace it, it was not impossible, but it would greatly reduce the flexibility of Chen Fan's arm in the future, and may even be unable to fight, which is definitely not acceptable to Chen Fan.
In comparison, the missing third kind of heaven and earth treasure is easy.
That is the fire of pure sun, specially used for sacred arms.
Guo Yi has a friend named Chunyangzi, and he enters the Tao with fire, so he can continuously generate pure Yang fire.
And this is the only one that Guo Yi has gotten among the three missing treasures so far.
Shenhunjingsha and Ancient God's Blood have even released news for half a year, and they have never given back.
