"What are you? Although it doesn't look good, the structure inside is extremely complicated", Taishang Laojun was very interested in the energy tester in front of Dongfang Yu, and pointed to the tester and asked Dongfang Yu.

It looks like it's just a delicate and small glass, but the structure inside and the circuit board collection are extremely complicated, even Taishang Laojun is surprised.

That's right, the energy tester made by Dr. Gallo at the beginning only measured the upper limit of 10,000, and it was so huge that it looked like half a helmet on the head.

Then he came to the plane of death, and let Na Nirvana help him improve it, becoming much smaller, and the upper limit of measurement has reached the level of 30,000, but it is an improved version made by combining technology and ghost technology.

The current energy tester is a version that Boomer's father spent a long time improving, and the upper limit of the measurement has not only reached the level of 150,000, but also looks about the same size as a pair of ordinary glasses, which has a larger measurement range, and the volume is more refined, and the structure is naturally countless times more complicated.

Taishang Laojun swept his thoughts, and naturally found this seemingly delicate and small thing, and the structure inside was very complicated.

"Well, this is called an energy tester for me, which can measure a person's energy value, uh, in short, the high and low ...... of cultivation."

Taishang Laojun was actually interested in the energy tester, and he also found that this energy tester was unusual? Dongfang Yu was slightly surprised, but when he thought of Taishang Laojun's identity, he was relieved and explained.

Taishang Laojun has the top Samadhi True Fire, he is not only the top alchemy master in the Three Realms, in fact, relying on the Samadhi True Fire, he is also a top refining master, such as the legendary Zhu Bajie's nine-tooth nail rake, which was refined by Taishang Laojun in the Bagua Furnace, which can be seen.

"Oh? Can you actually measure the level of cultivation? Hearing the role of this energy tester, even Taishang Laojun's eyes lit up and he was very interested.

What the so-called energy value is, Taishang Laojun naturally doesn't know, but when it comes to cultivation, Taishang Laojun certainly understands.

Throughout the ages, great monks, with their qualifications and the length of time they have cultivated, of course, there will be high and low cultivation, but what is the specific comparison between high and low? But it can only be understood, not spoken, and now, there is something that can really measure the level of a person's cultivation?

"Come on, come on, let Lao Dao give it a try", full of interest in this energy tester, after asking about the use of this energy tester and the meaning of these Arabic numerals, Taishang Laojun quickly understood the meaning of the usage and value, wearing the energy tester, his eyes fell on Dongfang Yu's body.

“8520？ Is your cultivation represented by this number high or low? Looking at the number represented by Dongfang Yu's cultivation, Taishang Laojun didn't know why.

Of course, the level of cultivation should be compared.

While speaking, Taishang Laojun measured the cultivation of the Qingniu next to him, with a look of surprise on his face, and said: "The cultivation of my Qingniu is actually more than 43,000, hahaha, Dongfang Yu, I didn't expect your cultivation to be so low, much lower than my Qingniu mount, and your cultivation is not much different from those heavenly soldiers and generals."

After comparing the cultivation of his own green bull mount, Taishang Laojun almost had an idea of the meaning of this number, and said with a smile on his face, I didn't expect Dongfang Yu's cultivation to be so low, but from his own perception, it is indeed about the same.

Taishang Laojun's words made Dongfang Yu's face a little dark, but there was no way to refute his words.

Indeed, he has also been in the heavenly court for these days, Dongfang Yu also has an understanding of the strength of those heavenly soldiers and generals, the energy value of ordinary heavenly soldiers is generally above three or five thousand, and the energy value of some small leaders in the heavenly soldiers is even more than seven or eight thousand, Taishang Laojun said that his cultivation is similar to those heavenly soldiers and generals, and he is really not wrong.

"This is really a five-rank official in front of the prime minister, it's just a mount, and it actually has more than 40,000 energy values, even in the Lingxiao Treasure Palace, it can be regarded as a good general."

Seeing the energy value of 40,003 of this green cow, Dongfang Yu was secretly surprised in his heart, but thinking about the time when he learned scriptures from the west, this green cow could make some moves with Sun Wukong, and it was reasonable to have this level of cultivation.

"Come, let's see how high my own cultivation is", after measuring the energy value of his Qingniu mount and Dongfang Jade respectively, Taishang Laojun already knew a lot about the function of this energy tester, and also knew that this measurement was indeed quite accurate, and immediately, he measured his energy value.

"Well, the energy value of close to 120,000 is more appropriate, the more profound the cultivation, the more difficult it will be to go further."

After looking at his energy value, he probably compared the cultivation gap between himself and the Qingniu mount, and for his energy value of 120,000, Taishang Laojun also nodded and agreed.

"Interesting thing, although this baby can't increase a person's ability, but being able to measure the opponent's cultivation level one step ahead can be regarded as a means to measure the difference in strength between the two sides to a certain extent, and it is indeed a good baby", this energy tester makes Taishang Laojun have a refreshing feeling, and he can't put it down.

"Moreover, this thing is not the appearance of a magic weapon, it does not contain aura, but other very rigorous and complicated structures, different from the means of refining, how did this thing come about? Can you explain it to me? ”。

As the top refining master of the Three Realms and Six Realms, the structure and principle of this energy tester itself attracted the attention of Taishang Laojun and was very interested.

"This ......", Taishang Laojun's words made Dongfang Yu a little embarrassed for a while, and he didn't know how to answer.

To put it mildly, although Dongfang Yu grew up in modern society, he has also studied some physics, chemistry and the like, but he is not a scientist after all, and for so many years, almost all the knowledge he has learned has been returned to the teacher, even if it is the periodic table, he may not be able to memorize it completely.

Let yourself explain it to him? Where does Dongfang Yu have this ability.

"It turns out that you just know it but don't know why?"

Seeing the embarrassed look on Dongfang Yu's face, Taishang Laojun didn't know how many years he had lived, of course, he was able to detect the reason for Dongfang Yu's reaction, and shook his head with some disappointment and said.

"Actually, although I don't know very well, but I have a woman, but I know very well, if you are really interested, I can take you to meet you?" Seeing that Taishang Laojun was very disappointed, Dongfang Yu pondered for a while, and then said, ready to introduce Boomer to Taishang Laojun.

This Taishang Laojun has an energy value of 120,000, his strength is amazing, and his status is also extraordinary, I don't know when I want Taishang Laojun to help in the future, if I can get his favor, this is definitely a great advantage for Dongfang Yu.

By chance, if he is so interested in science, let Boomer teach him well, this is definitely a good and harmless thing.

"Oh? It turns out that your woman understands this, you kid is so blessed, quickly bring her to Tushi Palace, I will wait for you in Tushi Palace ......", listening to Dongfang Yu's words, Taishang Laojun, who was still a little disappointed, said with great joy.

While speaking, he seemed to be afraid that Dongfang Yu would release his pigeon, shook the energy tester in his hand, and said, "This will be put here for the time being, you go and come back quickly."

Well, Taishang Laojun took his energy tester as collateral, which is enough to see that he attaches great importance to science and technology, of course, the more Taishang Laojun attaches importance to it, this is also a good thing for Dongfang Yu.

Therefore, Dongfang Yu didn't say anything, nodded and said goodbye to Taishang Laojun, and then went directly down to Nantianmen and returned to Huaguo Mountain.

Came to the Boomer in Huaguo Mountain, Dongfang Yu told Boomer about this matter, and also understood that it was very important for Dongfang Yu to have a good relationship with that Taishang Laojun, Boomer nodded and agreed.

As the top refining master of the Three Realms, that Taishang Laojun is very interested in this scientific method, in fact, in the same way, as a top scientist, Boomer is naturally very interested in the refining method of this mythical world.

Even if there is no relationship with Dongfang Jade, as long as there is an opportunity, Boomer is very willing to contact Taishang Laojun.

Here in the fairy world, after getting this energy tester, it was like a child getting a new toy, Taishang Laojun was not in a hurry to go back to his Doushi Palace, sitting on the back of the green ox, wandering around in the fairy world, and constantly testing the cultivation of those immortals with the energy tester.

"Well, the cultivation of this heavenly soldier is not low, it actually has 8200 points, which is quite good."

"Huh? Isn't that the Demon Rite Sea among the Four Heavenly Kings? Well, the energy value is 31,000, which is good."

"Huh? Why is the roaring dog of the Erlang God here? Let me see, oops, this Howling Sky Dog actually has 51,000 cultivation? Tut-tut, these four heavenly kings are really not as good as dogs."

Looking at the energy value of the roaring dog, Taishang Laojun said with some surprise, this Erlang God is indeed very capable, a dog is actually so strong.

Moo......

Listening to the roaring dog actually has 51,000 cultivation, which is a lot taller than himself, this Qingniu under the seat of the old monarch is a little unconvinced.

"Qingniu, don't be unconvinced, that Erlang God Yang Jian is the top god of war in the heavenly court, this roaring heavenly dog follows the Erlang God to fight in the south and the north, it is not surprising that he can have such a cultivation."

Listening to the unconvinced cry of his mount, Taishang Laojun said with a smile.
