The blue gold tree is more than 50 meters high, and the shade is more than 100 meters wide, so that several people can hug it.

Between the swings of the metal branches and leaves, the aura of heaven and earth and the essence of the Great Sun within a radius of ten kilometers were swallowed, and after refining and screening, the stars fell in dots.

Absorbed by a young man in Tsing Yi sitting cross-legged under a tree.

This is happening every day for decades.

Now, at last, it's time for a change.

The last bit of heaven and earth aura and the essence of the Great Sun Essence were swallowed up, and after the complex meridians of the "Wanhua Magnetic Yuan Sutra" were refined, and finally turned into a tiny drop of mana beads dripping into the dantian.

Tick!

In the dark, a clear voice was heard, the big beads and small beads were as crisp as falling on the jade plate, and the mana in the dantian reached two-thirds of the level, and it encountered a layer of tough film, and it could not be increased by a fraction.

"It's the peak of the middle stage of foundation building."

Jiang Ding opened his eyes, and the blue light in his eyes flashed.

"Broken."

He said softly.

There is nothing to prepare for, and since he has cultivated so far, he has never experienced what is called a bottleneck, but he just regards it as a sign that he is about to break through to the next realm.

The blue sea of dantian was restless at this time, tumbling, and countless waves rose and fell.

If you look closely, you can see that drops of mana are condensed into a sword shape, densely packed, and countless silver fish surge, breaking the sword intent contained in it.

The waves roll and accumulate a huge wave,

Slam into the transparent bottleneck!

Click!

The solid bottleneck appeared in dense cobweb-like cracks under the impact of the huge force, and fine sword qi poured into the cracks, consuming them, devouring them, and cutting off the last small fragment.

Then, the sea of dantian was no longer hindered, and happily poured to the place where it had never been.

Jiang Ding's aura also skyrocketed, and his divine sense was also changing, from a six-kilometer radius to an eight-kilometer radius, which was already close to the sensing range of the sword intent.

The biggest movement is the blue and gold tree.

In the rumbling sound, the trunk of the tree that can only be hugged by several people broke through the ground and grew into the sky, rising more than ten meters in just a few breaths, and becoming a tree more than sixty meters high.

The shade of the tree spreads outward, grows, extends more than 20 meters, and becomes a canopy of blue metal branches of more than 120 meters, swallowing the aura of heaven and earth and the essence of the great sun within 10 kilometers, and the blue sun between the shades of the trees is a little brighter.

"Sixteen years old, late stage of foundation building."

A few days later, Jiang Ding's breath stabilized, and he opened his eyes, revealing a hint of joy: "The strength has increased a bit." ”

He was not in a hurry to get out of the customs, but after steadily cultivating to the realm for more than ten days, he took out a jade bottle, and his divine consciousness and sword intent poured into it.

Sonor!

A sword roared.

Only a small half drop of the molten magnetic crystal nucleus was cut off, and the blue gold branches hung down, collapsed straight, pulled up the gray mist, and sent it into the shade of the tree, in the blue sun.

Splitting, melting, absorbing.

Within a quarter of an hour, the gray mist had been absorbed and melted into the leaves and bark, forming wisps of undetectable gray imprints on them.

After more than 20 years of accumulation, it has finally undergone qualitative changes again.

Rumble!

The blue and gold tree seemed to explode, and the branches of the tree collapsed straight, and then formed parallel lines, like the magnetic field assisted the dotted line, and the meta-magnetic light visible to the naked eye erupted between the branches, allowing the branches to follow the movement of the planet's magnetic field, completely uncontrolled.

After a long time, it finally calmed down, and the branches fell down, returning to their usual swaying in the wind.

"Integrate 6,000 strands of melted magnetic crystal nuclei, Dacheng."

Jiang Ding closed his eyes for a moment and opened his eyes: "Affected by this, the ampere force of the electromagnetic cannon has become stronger, and the speed of the flying sword has increased by a bit. ”

In his heart, he faintly wanted to pull out the blood transformation ancestor Mu Tianxue and kill him.

"Forget it, limited by the previous promise, I have to find a way to get her out of the Chu State."

"It's too much trouble, I'll talk about it when I have a chance."

Gathering his breath, he turned into a gray-blue light and flew towards the sky-covered branches and leaves of the Divine Tree overhead, and found a leaf with the mark of the scorched black sun and flew into it.

"Welcome to the Seifuze University Science and Technology Building-Dainichi Ruins Laboratory."

The gray sky and the ruins of the explosion pits and sword marks came into view, and the air was filled with the smell of radiation.

flew dozens of kilometers, Zhang Junsheng and Wu Mengsha were all there.

"Hi, Jiang Ding."

Wu Mengsha threw over a bunch of ancient books that were specially sealed with a sense of ceremony: "Your electromagnetic sword is ready, and the magic array spirit tester of the Xianmen Academy of Sciences has not found any loopholes, you try it, there are still methods that need to be improved." ”

After more than ten years of research and development and testing, a Yuanying monk and a large number of Jindan monks participated, and with the assistance of various research institutions in Xianmen, a large number of library points and spirit stones were consumed.

The second-order electromagnetic system sword escape has finally been successfully developed!

"Thank you, senior sister, thank you mentor and senior brothers."

Jiang Ding's spirits perked up, and he took the half-person-high thread-bound ancient books, turning the pages one by one.

The sound of turning the pages was very fast, and it was almost swept at a glance, and the spiritual texts containing a huge amount of knowledge in the books were completely understood, and there was no special difficulty.

He was deeply involved in the research and development of the electromagnetic sword, especially the kendo part, and almost every change in direction was related to him, and he put a lot of effort into it.

A few days later, the last page of the book closed.

"Not bad."

Jiang Ding put his book aside and closed his eyes slightly.

The mana in the body quickly began to change in a complex structure, and the surface of the body lit up with gray-blue light, with the unique sharpness of the sword, and the ethereal electromagnetic system, thunder and lightning weather.

He won't take these books with him, and he will be in and out of the other world all year round, and there is a possibility of leakage.

Zhang Junsheng, Wu Mengsha and the others all looked over here, a little nervous.

No matter how correct the theory is, if it cannot be applied in practice, it will be useless, and more than ten years of hard research work will be in vain.

Airplanes!

After more than a dozen breaths, a blue flying sword appeared in Jiang Ding's eyebrows, and the dotted line formation of the surrounding Dao Dao Spiritual Energy Gathering Array flashed, but there was no attack, but the body merged with the sword light, and disappeared in the sound of the air explosion.

"This speed ......"

Wu Mengsha's expression was a little sluggish, and her divine sense swept over, only to see that in the sky in the distance, a sword-shaped gray-blue sword light shuttled up and down, and the speed was faster than that of the late Jindan monks.

"Da Ri Jianzi, worthy of his reputation, I guess I can't beat him now."

Another senior brother said, and there is honor.

Listening to the tone, it is a bit like showing off one of the top research results of his major, so that others will hurry up and come to me to envy and hate.

"You're only in the middle of Jindan, and you can't beat him alone."

Wu Mengsha glanced at him.

Shout!

A moment later, the gray-blue sword-shaped light returned, braked precisely in front of everyone, and the azure flying sword flew into the center of the eyebrows.

"No problem."

"The expected speed and flexibility have been met."

Jiang Ding said with a happy face: "Thank you, senior brother and sister, and mentor." ”

"Thank you, it's originally a research task that is part of our major."

"Keep working."

Zhang Junsheng waved his hand, and the others entered the research state again, discussing the progress of various research projects in this specialty, such as the Da Ri Yu Dan, the Dyson Sunglasses Sword Domain, and the rescue excavation of the Da Ri Tianchi.

"Okay."

Jiang Ding was also involved, he had an extremely keen intuition in the way of the sword, and he had a special attack on all the studies involving the Great Day Sword Pavilion, which could greatly speed up the progress of the research.

"Wasted Copper ......"

He muttered to himself.
