When there is pressure, there is motivation, Xu Hao changed his laziness in the past, and finally cared about his cultivation.

Xu Hao now wants to improve his strength, but he doesn't have peerless magic skills in his hands, and the magic tricks exchanged with Yuan Tiangang can only be cultivated to the earth immortal, and it is not very efficient.

Xu Hao has cultivated, even if he cultivates for a day, it can only increase his mana by a little, he calculates, even if he cultivates for a year, he can't increase his mana by one percent, Xu Hao, who is used to making rapid progress, really can't stand such a turtle-crawling cultivation growth rate.

Fortunately, Xu Hao has the magic weapon of quantum computer, after Xu Hao uses mana to refine, the quantum computer can be integrated into Xu Hao's body, and even Xu Hao can use it to control his own cultivation, just like hanging up, it can help Xu Hao absorb aura and refine mana when it does not affect Xu Hao's daily life, of course, but the efficiency is not high,

Xu Hao took Dao Yu as the unit of calculation, Dao Yu has been practicing for sixty years, which is regarded as a Jiazi mana, Xu Hao found that although his mana is of high quality, the amount is only more than ten times that of Dao Yu, which is about equivalent to a thousand years of mana.

And with his own immortal body, the speed of cultivation was about thirty times faster than that of Dao Yu. Dao Yu cultivation is also more diligent, unless there is something, he must practice for 8 hours a day, and Xu Hao is a plug-in for 24-hour cultivation, so Xu Hao's cultivation efficiency is only 10 times that of Dao Yu, but Xu Hao is an immortal, Dao Yu is not even a golden pill, such a comparison, Xu Hao has a very intuitive understanding of the difference in his qualifications for the first time.

But this is also a matter of no way, Xu Hao used to be just an ordinary person, and now even if he becomes an immortal, his qualifications are very poor, even now he is not too good, and he cultivates step by step, even if he cultivates to the level of an earth immortal for thousands of years, he may not even be able to reach the level of a heavenly immortal when the world ends.

Of course, there is also a way to improve Xu Hao's qualifications, which is to strengthen his body with aura, control the power of his bloodline, and then find the best bloodline from it, and constantly use mana to warm and refine, just like a snake and a dragon, so that his physique can be optimized by genetic mutation, but this method is not suitable for Xu Hao, because it not only consumes a lot of mana, but Xu Hao, a modern person, does not have a dragon and phoenix, fairy bloodline, no matter how to optimize his bloodline, at most there will be a Tyrannosaurus rex.

Xu Hao sorted out what he had learned and found that it was most suitable for a person with low qualifications like him, and to quickly improve his strength was to use merit in addition to the Demon Dao, and earning merit was Xu Hao's best thing.

But when Xu Hao's action had not yet begun, trouble found Xu Hao first.

The fact that he used the elixir of immortality for Wei Zheng was finally exposed, and there were monks in the imperial court, and these monks naturally knew that Wei Zheng's situation was fundamentally that his longevity was exhausted, and his illness was just an external manifestation, but later Wei Zheng not only recovered from his illness, but also became vigorous, and even almost made Li Shimin angry, these monks naturally began to suspect Wei Zheng's situation, and naturally found that Wei Zheng had increased his lifespan.

Wei Zheng's lifespan has been increased, these monks are crazy with jealousy, they have to pay countless years of penance to increase their lifespan to break through the realm, and even have to suffer 500 heavenly tribulations, but their souls are scattered, but now Wei Zheng is easy to obtain, how can this not make them jealous, jealous of the enveloping offerings, and immediately told Li Shimin the news.

Although Li Shimin is the emperor of the Xianxia world, he still can't live forever, knowing that the news is repaid, he immediately sent a hundred horsemen to let them check, and it was soon sent to Xu Hao.

immediately sent an attendant to invite Xu Hao into the palace.

Li Shimin is also a famous emperor in history who seeks immortality, but in the end he was poisoned by the pill, he came to invite Xu Hao with such fanfare, Xu Hao naturally knew why.

If there was no warning from Heavenly Dao, with Li Shimin's status as the top five emperors in history, the Immortal Pill would have been given, but now that Heavenly Dao has warned him not to mess around, Xu Hao naturally did not dare to give the Immortal Pill to Li Shimin again.

Xu Hao used mana to create a volume of "Recipe for Longevity", of course, it is not a technique, nor is it a recipe, but a method summed up by some modern experts to maintain longevity, it is better to have this than Li Shimin to poison him, and then Xu Hao handed over this "Recipe of Longevity" to Li Shimin's attendants.

Then he flew out of Chang'an City and disappeared in front of Li Shimin's attendants!

Li Shimin couldn't find Xu Hao's identity for hundreds of miles within a radius of Chang'an City, but he just looked at the "Recipe of Eternal Life" in his hand with disappointment! He wants immortality, not health.

And after Xu Hao flew out of Chang'an City, Dao Yu caught up, he finally hugged Xu Hao's thigh, how could he let Xu Hao go like this, he begged Xu Hao to accept him as an apprentice and learn the method of immortality, but how could Xu Hao accept a disciple who was more than 100 years old, but thinking that because of his drag, Dao Yu lost his Taoist temple, and the age difference between the two was not much, so he accepted him as a junior brother.

The two hid on Taiyi Mountain, and then used magic to establish a small Taoist temple, he didn't want to leave Chang'an City like this, because he walked the way of merit, and it was easy to earn merit in the public gate, in addition to invention and creation, it was obviously the best way to earn merit for the benefit of the official.

After thinking about it for a month, Xu Hao used spells to create a clone, set up a small vest, contacted Wei Zheng, and wanted to ask for a petty official, and Wei Zheng also knew the price Xu Hao paid for him, so he used his connections to make Xu Hao a small official of the Ministry of Works.

On the first day of the successful Ministry of Works, Xu Hao contributed a horseshoe, which could double the combat effectiveness of the cavalry of the Tang Dynasty, and Li Shimin was overjoyed and immediately promoted Xu Haoguan to a higher level.

In the second year, Xu Hao made a blast furnace to improve the iron-making efficiency several times, so that the soldiers of the Tang Dynasty could become an all-iron army.

In the third year, Xu Hao got out of the earth cement, which could not only build roads, but also quickly build fortresses and camps at the border gates.

Xu Hao's merits even Wei Zheng admired and said, "Brother Xu, it's really a waste to cultivate the Dao with your talent, but fortunately, now it's finally on the right path." ”

In the past three years, Xu Hao has made more than these three, such as the Quyuan plow and the waterwheel, and only then did he get out the glass and out-of-season vegetables, but not as much as the above, especially the glass, he thought that this was a money-making project, where to know that the monks in this world have already practiced the glass, everyone knows that this is made of sand, not very valuable, and it is not even as precious as porcelain in Datang.
