From the record point of view, the relationship between the four spirit kings at that time was very close and mutual trust.

There is no limit to the fusion of the origin of the blood, any creature in the four spirits can try, get the ability of the origin of the blood of God.

After the strength of the four Lingmen Gates increased, it began to expand continuously, and the model was getting bigger and bigger.

At the same time, the demand for the origin of the blood is growing.

Even the geniuses in the four spirits can only be merged with a small number of people.

Most of the people of the four Lingmen tried many times and all ended in failure. The failure rate was extremely high.

The transfer came from an attempt at the bitter tree.

He subdivided the origin of the gods!

The method of separation is not complicated.

The human spirits captured a large number of "herons" for experimentation. This white-skinned, bi-winged rat was forcibly injected with a drop of originated blood.

How powerful is the energy of the origin of the gods?

This heron is simply unbearable.

After the huge part of the heron rat absorbs the origin of the blood of God, there is only one consequence, which is the explosion and death.

The hundredth time is the same, the same is true for the first ten thousand times, and the ten thousandth is still the same.

Fortunately, the number of herons is very large, and tens of billions of herons are found in the forest closest to the four-door gate.

For decades, the most important task of the monkey spirits in the Monkey Gate was to catch the heron...

When the dead heron was close to a million, finally a heron survived!

It is not that this heron has anything special, but that the origin of the **** of blood is "tired".

At the beginning, both "孽" and "hound" believed that the power of the origin of the gods was endless, but the bitter tree did not take it for granted. He felt that everything had limits.

As for the Monkey King, "胤斟" is completely uninterested in the mystery of the origin of the blood, and is not willing to understand, so what is bitter tree said.

Therefore, the study of the origin of the blood of the gods, only the human spirit door and the monkey spirit door support, the bird Lingmen and the snake spirit door lack of interest.

When the bitter tree directly poured the blood of the origin into the body of the heron, it was keenly aware that there was a slight change in the blood of the origin.

The endless energy of the origin of the blood of God does not apply to the process of merging blood!

The bitter tree even assumes the ability to originate from the blood of the gods, can be seen as a kind of "poison", a poison of rejection.

And this "rejection of poison" is not endless.

After the poison of rejection caused countless herons to explode and died, the "toxicity" weakened. The drop of originated blood finally surrendered and successfully merged into the "heron".

When this heron rat merged with the origin of the blood, it immediately showed incredible power!

It directly acquired some of the power of the origin of the gods!

Be aware that at that time, the ability to acquire the blood of the origin of the gods will immediately become an elite.

After the ability of this heron to gain strength, the strength and speed have been greatly strengthened. After killing the three human spirits, they intend to escape. Fortunately, the bitter tree came to the news to be able to subdue the heron.

At that time, the bitter tree was overjoyed.

After all, this "rejection of poison" is only a conjecture of bitter trees, and this conjecture is finally justified.

From this heron, I got a new blood.

The human spirit called it the source of blood!

This source of blood has a single ability to originate from the blood of God, but even this ability is not complete.

Some sources of blood inherit one-tenth of their own abilities, and some are only two-tenths...

Compared with the ability given by the **** of the origin, the power of the source blood is indeed greatly reduced, but its adaptability is very good!

Most of the spirits in the four spirits can be merged!

The genius of the world is a minority after all...

The origin of the gods of blood can only be used in very few people, and now almost everyone can use it. As soon as this news comes out, the impact on the four spirits can be imagined.

However, the bitter tree was bent on it at the time and was only allowed to be used on the monkey door.

When Luo Zheng explained to this place, Yuan Shi Tianzun, who was listening to the audience, sighed softly. "I am afraid that the problem is here..."

"The four Lingmen is a whole. Although the monkey spirit is hard-working, it can be a partiality," said the son-in-law.

It is possible to decompose a source-level blood vein from the origin of the **** blood. The monkey spirit gate is indeed a great achievement. After all, they are tired of catching the heron and the bitter tree can complete this experiment.

However, the bird's door and the snake's door are inevitable.

Of course, this kind of emotion was nothing at the time, but it was not certain.

Now that the four Lingmen have come to this step, I am afraid that it is not decided by this matter.

After obtaining the first source of blood, the footsteps of the bitter tree experiment did not stop, and continued to capture a large number of heron experiments.

When the second million heron died, the bitter tree fruit did not have the second source of blood, and the second source of blood was completely different from the first.

Followed by the third, fourth, fifth...

The source blood of various abilities is concocted by bitter trees.

The only thing that has been ravaged is the heron in the forest, whose bones are piled up in the human door.

But soon the bitter tree is not satisfied with the power of the source.

The source blood can certainly exert the ability to originate from the blood of the gods, but the power exerted is only one or two.

Still too weak...

The bitter tree summoned a group of people's spiritual thinkers to discuss. They are all intelligent and superb people. After a few days and nights, they finally come to a conclusion.

The heron is too weak and the ability to acquire it is naturally weak.

In order to obtain a stronger source of blood, you must use a stronger life to integrate.

There are not many strong and numerous creatures in the main world, and the choice of the four spirits is not wide.

However, after some hunting, several targets were also selected.

If the body size is dozens of feet, but the number and number of "dark army ants", such as "black scorpion" and other main body creatures.

It is also difficult to capture these main creatures in large quantities, but both the Snake Spirit and the Birds Gate understand that the direction of the human mind is right, and they also lead the people to participate.

Under the cooperation of the four divisions, the efficiency is naturally greatly improved.

The fusion experiments for these more powerful creatures soon began.

The result was very smooth. When more than 100,000 "dark army ants" were sacrificed, the bitter tree once again gained the source blood. This time, the source blood was really much stronger, and the power was equivalent to 40% of the individual ability of the origin of the gods!

The power has more than doubled!

The bitter tree is named as the root-level blood, and the previous source blood is called the source-level blood.

With the popularity of source-level blood and root-level blood vessels in Silingmen, the strength of Silingmen has skyrocketed again.

After all, they are able to "produce" this kind of elite in batches, and there are few aliens in the main world that can compete with them.

Even so, bitter trees are still not satisfied.

He wants to get stronger blood and even directly integrate the method of originating blood. But this time, the bitter tree did not do so, because in the main world, there was no race that was very strong and numerous.
